Message
from the Chairmen
The field of e-business, e-education, and
e-science in general is fast growing, and up to now it has been noticed that
there is a large body of unpublished knowledge that needs an appropriate forum
for its presentation. This was the main rationale behind the idea to organize
the IPSI-2004 international conference series. The theme of this particular
conference is synergistic interaction of Enterprise Knowledge, Modern
Technologies, and the Internet.
A sign of
appreciation goes also to all the people who worked hard for making this
conference a success: Nenad Korolija, Jelena Krunic, Miroslav Radakovic, Aleksandar Stanic,
Sanida Omerovic, Senad Omerovic, and others.
Welcome to the CAITA-2004 PURDUE conference. We hope you will all enjoy the event as much as
we have enjoyed in contributing to its preparation.

Neural
Network Analogs, Resource Distribution Theory, and Functional Evolutionary
Optimization Algorithms
Modern advances in economic
modelling coupled with computational string theory have led to highly
predictable emergent properties that arise under non-stationary vortices that
resemble neural networks in a surprising number of ways. Similar to computational networks, neural
networks can be modelled under evolutionary optimization schemes that, like
economic models, describe various attributes of cost- benefit analyses. Such paradigms are similar to behaviour
modification and assessment models, including the prisoners dilemma, and even
simpler associations, like tit-for-tat.
My research program takes a novel approach to evolutionary game theory
and resource optimization schemes by using string theory algorithms to
de-couple the resource allocation (inputs) from the resource uptake (outputs)
aspects of these types f associations.
I show that the optimization of resource redistribution schemes can be
modelled as a simple linear function, and that tests of the model fit
experimental data with statistical significance greater than six-sigma.
A Thin
Security Layer Protocol Over IP Protocol on TCP/IP Suite For Security
Enhancement
Mohammad Al-Jarrah, Abdel-Karim R. Tamimi
In this
paper, we proposed a thin security protocol (TSP) over IP protocol that
enforces a data security through encryption. This protocol consists of two
components. The first component manages and establishes a secure channel
between any two communicating hosts. This component uses three-way handshaking
and public key cryptography (PKC) to create virtual secure connection and
security entity (SE). SE holds the secret key cryptography (SKC), and addresses
of two hosts that share this SKC. The second component of TSP protocol encrypts
and encapsulates the coming transport layer packet into TSP packets. The TSP packet header consists only of two
fields each of them is one bytes. The first field identifies the TSP packet
types such as request, acknowledgement, transport layer data, or channel
terminating packets. The second field carries information about the transport
layer protocol.
Dynamic
Aspect Oriented C++ for Safe Upgrading Without Restarting
Sufyan
Almajali, Tzilla Elrad
This paper presents an extension
to C++ to construct easily upgradeable systems without restarting. With current
applications of the Internet, the need for new structures to achieve a high
degree of dynamic adaptability becomes apparent. Here we propose to address the
issue of modularization of Internet services whose implementation would
otherwise be scattered in many different places. The advantage of such
modularization is that these services become easier to control and adapt at
runtime. The cost of extracting what otherwise would be scattered code and
modularizing it is the need to provide mechanisms to quantify the points in the
program where the code needs to run. In addition, the issue of switching from
one system version to another safely is addressed. The paper presents the DAO
C++ language - Dynamic Aspect Oriented C++ system, its implementation and its
potential applications for dynamic applications upgrading.
Enviromentally-Induced
Vibroacoustic Disease
Mariana Alves-Pereira, Nuno
A. A. Castelo Branco
Vibroacoustic disease (VAD) is a
whole body pathology caused by excessive exposure to low frequency noise (LFN),
and characterized by the abnormal proliferation of extra-cellular matrices.
Research into the effects of exposure on humans began within occupational
settings, namely, aircraft technicians, pilots and flight attendants. However,
numerous cases have now been documented in individuals who are environmentally
exposed to LFN, and not occupationally exposed. The implications of an
increasing number of ill individuals added to the inadequacy of noise-related
legislation and policies, as well as the ignorance of mainstream physicians
regarding VAD, has led an unsustainable and unethical status quo.
Reformulating
Usability
David
Ambaye
Over the
past decade, the use of ethnography as a serious approach for narrating
technological intervention in organisations has been evolving very firmly in a
positive direction. In contrast, the use of ethnography for targeted research
objectives such as theory building and testing is less common. This paper
describes the design and implementation of a series of such ethnographic
studies aimed specifically at building a new understanding of what is meant by
the notion of system usability. The use of analytical techniques known as
usability scenarios that serves as the basis for this reformulation is also
described. Finally, a new definition of
system usability is proposed and twelve key dimensions are described.
Simulation
Supported Optimization of Container Storage Place
Krzysztof Amborski
Numerical optimization of all activities taking place in
container terminal enables among others proper design of routes for
terminal vehicles transporting containers to and from storage place and
performing loading operations on it. Storage place in container terminal is
used to store containers, which cannot be taken out within short time. Because
storage place is one of the parts of the terminal, its simulation should work
in a system describing whole terminal. In simulation of storage place there are
two crucial points: synchronization of events and optimization of vehicles
movements. Because some events can occur simultaneously, it is indispensable to
introduce priorities in their management. Therefore highest priority has been
attached to truck service (i.e. loading containers on trucks), lowest priority
to the transport of containers inside storage place. Optimization procedures
ensuring full dynamic evidence of containers being on the terminal enable best
use of terminal vehicles. In this paper two quality indices are taken into
account first minimizing energy, second minimizing time of the service. First
index is deciding when there is reserve in time and therefore cost of loading
is prevailing. Second when the terminal is almost full of containers waiting
for immediate service.
Using Pattern to Reduce Compilation Dependencies in Large
Scale C++ Project
Zeeshan
Amjad
Making large scale project is
challenging task. There are lots of problems in large scale projects, which are
not visible in small projects. One such problem is compilation time that became
very large if project is not organized properly. Design Patterns, which helps
to make logical design of project, can also be used to manage the physical
dependencies of a large scale C++ project.
An Experience in the Evaluationof
E-Learning for IT Training and Certification
Louiza An, Luis G.Restrepo
Looking to
promote within the country a socially wide ranging IT exposure that would be
sustainable and have a positive impact on the countrys development, the
Colombian Government was inspired by Indias experience in the development of
its own successful Information Technology sector and went on to construct a
programme called the Connectivity Agenda. This programme is comprised of the
following six strategies: infrastructure access; education and training;
e-commerce; e-government; boosting the IT industry and increasing Colombias
website coverage. One of the components of the Education and Training strategy
is the National Project of Training and Certification in Information Technology
which looks to train, to an international standard, some 5000 professionals
within 7 years. After a year of development the Projects advances were
evaluated in various cities around the country. Using the evaluation from one
of those cities we have set out the following, principal results which can act
as a reference for other countries who wish to implement similar IT projects.
E-Commerce:
A Brave New World
Timothy
Asiedu
The
essence of this paper is to explore the business and the technologies
associated with E-commerce in a developing like Ghana. In analysing the usage
of e-commerce in Ghana, a critical study of the target industries like Banks,
Mining, Insurance, Courier, Internet Cafes, etc will be carried out. In
considering the target industries, the category of users in those industries
will also be looked at. Although E-commerce hasnt been with us for long, the
rate at which it is being developed requires a study of its socio-economic
impact in a developing country like Ghana.
Weblogs,
RSS (Really Simple Syndication) Specifications, OPML, and the Development of
Weblog Ecosystems
Douglas
Bass
The
phenomenon of weblogs (or "blogs") has rapidly developed over the
past year, with the development of a number of technologies that not only
facilitate online journals, but promise to revolutionize the internet
experience by greatly increasing the speed at which new content is delivered
and received. This paper will describe
the development of the RSS (Really Simple Syndication) specifications, the
growth in the use of Outline Processor Markup Language (OPML), and the
development of environments for ranking the relative importance of blogs
(commonly known as blog ecosystems).
The relationship between the blog community and traditional media
channels will also be examined.
Managing
Contribution
William G. Beazley
This paper is an overview of a
management philosophy based on contribution, rather than cost. Contribution, as I define it, is intuitively
simple and satisfying: Contribution is the value added to an expected opportunity
to deliver products and services. For
comparative purposes, contribution is measured by the net present value of the
expected value of the value delivery. Contribution Analysis is the study of
activity impact on expectations of delivered (or returned) value.
NEESgrid Using Grid Technologies to Build the National
Virtual Collaboratory for Earthquake Engineering
Cristina Beldica
NEESgrid is the system
integration component of the George E. Brown, Jr., Network for Earthquake
Engineering Simulation (NEES), a national research facilities program supported
by the US National Science Foundation. Its objective is to create a virtual
laboratory for earthquake engineering research, by linking the state-of-the art
testing facilities distributed across the United States in addition to high
performance computational resources and data repositories. The key element of
NEESgrid is a powerful middleware architecture underlying the entire system
that supports higher-level information services accessible by end users; is
built upon the standards emerging from the Globus Project and the NSF
Middleware Initiative (NMI); and is designed to be scalable and extensible.
Impact of
E-business, E-education, and E-science Upon Traditional Native American and
Hispanic Cultures
Irene I.
Blea
This
presentation explores the impact of e-business, e-education, e-science upon
traditional Native American and Hispanic US cultures. More specifically, its focus is upon the gaps, lags and advances
of technological knowledge and implementation.
In some ways the advances have leveled the playing field between males
and females, but has distanced the young from the old.
Visual Literacy Merging Global Cultures
Peggy Blood
In the
increasingly digitized world of higher education it is time we rethink the
traditional education delivery system. Spurring of technology has contributed
to pedagogical delivery, not its structure advancement. Academia moves slowly in adjusting to
change. How can technology structure
and deliver really great learning experiences in the humanities? Teaching in
the humanities should be a global collaboration, i.e., a professor who has
lived, experienced and been educated in Russia would be the sole teacher of
Russian culture. Thus, students will objectively compare and contrast Russian
philosophical thoughts with those of Asians, Americans, and etc professors. The
bias is natural and is not skewed to one side.
The
Problems and Benefits of Outsourcing Technology Jobs
Thomas D.
Brumett
Much of
the discussion regarding the outsourcing of jobs by US companies is focused on
the resulting loss of jobs to the US workforce. This deeper look at this trend, particularly in the high
technology work place addresses the longer term impact on innovation,
competitiveness, productivity and education.
If properly applied, outsourcing can work to the benefit of technology
professionals and their employers; if misapplied outsourcing can be first steps
leading to technical obsolesce of entire industries in the US.
Formal
Description of the E-learning Adaptive Web System
Miroslav Bures, Ivan Jelinek
This article deals with formal
description of the adaptive web system. Adaptive web system monitors particular
users behavior and characteristics. Based on them, the system compiles a
resultant adapted document. This document corresponds to users qualification
and capability, preferences and his/her specific needs. For example, we can
adapt user interface of document, its information content and layout, topology
of hypertext or other features. The aim of using of adaptive approach to
student in E-learning is to increase effectiveness of E-learning process, to
improve its ergonomic quality and to adapt E-learning process for the disabled
students. The aim of our work is to create a system for automated
implementation of adaptive web systems. It represents a non-trivial engineering
process, which needs to establish a formal description of the system, like in
many other scopes of computer science. Beside that, formal description of
adaptive web system is needful in other cases, for example exact description of
adaptive document behavior.
Advanced Computational Modeling of Vapor Deposition in a
High-Pressure Reactor
Beatriz H.
Cardelino, Craig E. Moore, Sonya D. McCall, Carlos A. Cardelino, Nikolaus
Dietz, Klaus Bachmann
In search
of novel approaches to produce new materials for electro-optic technologies,
advances have been achieved in the development of computer models for vapor
deposition reactors under microgravity conditions. Numerical simulations are
invaluable tools for costly and difficult processes, such as those experiments
designed for high pressures or to be performed in space. Indium nitride is a candidate compound for
high-speed laser and photo diodes for optical communication system, as well as
for semiconductor lasers operating into the blue and ultraviolet regions. But vapor-deposited InN exhibits large
thermal decomposition at its optimum growth temperature. In addition, epitaxy at lower than optimum
temperatures and subatmospheric pressures incorporates indium droplets into the
InN films. However, surface
stabilization data indicate that InN could be grown at much higher temperatures
in high nitrogen pressures, with microgravity providing the necessary laminar flow
conditions. Numerical models for chemical
vapor deposition have been developed, coupling complex chemical kinetics with
fluid dynamic properties.
DSCP: A
Secure and Extensible Distributed Computing Platform
Paul James
Caritj, Nicholas Paul Johnson
Existing systems for distributed
computing all have critical failings that prevent them from becoming practical
computing tools; They allow for neither the secure execution of arbitrary
third-party algorithms nor the monetary reimbursement of end-users for the use
of their computing resources. DSCP has been designed to overcome these
failings; it allows for safe execution of third party code across the network,
while at the same time enabling providers of consumed resources to profit off
of membership in said network, yielding economic incentive to join. Public key
encryption is also employed to both secure and verify the sender of every
message passed within the system.
Sun Tzu and e-Strategy of Intellectual Property Right (IPR)
Muchiu Chang
In this paper, we explore the
philosophical foundation for the e-strategy of intellectual property right
(IPR) based on Sun Tzu: The Art of War. First of all, we find that using
modelling and simulation for evaluation and decision-making is a modern trend
of implementing Sun Tzu's concept of temple calculation. Our patent-pending
works in virtual validation and verification of product specifications by
modelling simulation have strategic importance in securing a market. Second,
Sun Tzu's defensive philosophy of securing ourselves first is preferable because
IPR is a protracted combat. From the human-brain orientation of IPR, we propose
to allow the individual member who creates the innovations to hold the IPRs of
his innovations and share the profits that come from his IPRs, which is a
corporation model of I pay, we work, we win and we share, so that there are
incentives to encourage people to think and offer the solutions, and let the
innovators free from the worry of being expendable. Finally, from our study of
US patent database, we notice that IPR can bring new opportunities to
individuals with know-how and skill, while INTERNET and world wide web (WWW)
along with open source software provide a new platform for innovators in
education (e-learning), creating innovation and manipulating marketing and strategy
with low cost.
Application of Web-Based
Electronic System to Diabetes Management
Jae-hyoung
Cho, Hyuk-Sang Kwon, Hee-Seoung Kim, Kun-Ho
Yoon
Considering
the recent dramatic increase in the number of patients and the medical cost, development of cost-efficient treatment modality for
diabetic patients is urgent need. So, we developed a web-based
electronic glucose monitoring system using internet as one of e-medicine systems.
With this system, we could show significant improvement of glycemic control by
randomized controlled trial and most participants were satisfied with this
system. Here we propose a framework to establish electronic medicine system for
chronic disease management. This system could become much larger and more brisk
with connection to mobile service system and with development of automatic data
analysis system.
A Study on the Impact of Organizational Learning to the Effectiveness of
Electronic Document Management Systems
Vincent
Cho
Processing documents
electronically can improve productivity, upgrade quality of product, avoid
redundancy and improve the customer service, etc. A popular system used in Hong Kong is Electronic Document
Management system (EDMS), which is an electronic way to manage and organize the
document more easily. It is an advanced solution
for companies to manage and organize tons of documents in the office.
On the other hand, organizational learning is the development of new knowledge of insights
that have the potential to influence behaviour. It was a measurable organizational capability one that could be
developed over time, and one that could be directly towards the achievement of
competitive advantage.
Data
Center Acceleration
Alan
Crouch
New services and growing
transaction volumes continue to accelerate data center networking requirements.
Todays multi-gigabit line rates suggest the messenger is plenty fast. The
solution to handling these volumes must therefore lie in how we handle the
message. Application consolidation, evolving workloads for Web services, and
other volume demands point to the need for protocol acceleration or offload to
efficiently convert network bandwidth into application performance. Intel
research and development believes the solution is new system technologies that
will help maximize CPU cycles for user applications while enabling the
processing of packet payloads at multi-gigabit line rates.
Water
Management in the Middle-East (GCC countries), Technological Perspective.
Anil
Dani
Water is the scares resource in
the Middle East. Creation of required water supply capabilities will be
consuming over 10 billion US Dollars in GCC countries. This region is very
active socio-politically for last several years. It is expected to remain so
for the next decade. New water resources development technologies will play an
important role in the life of a common person as well the local governments.
The paper is an effort to address possible impact of water purification, waste
water treatment and desalination technologies on environment, life style of a
common citizen. This may give an insight about local needs and key success
factors for new technological developments.
Combining Old Teaching Methods and New Technology to Create
Happier Students.
Anne DArcy-Warmington
The tacit dimension of teaching
and learning even with all the advances in technology still remains important
today. Emotions and environment whilst
learning mathematics become memories that are foundations to mathematical
comprehension. New advances with online
assistance and assessment serve to enhance teaching strategies not necessarily
replace them. The creation of friendly face for both lecturer and computer
means students can feel free to study further or may just leave with good vibes
about mathematics hence reducing the mathematics negativity cycle. The student may now see the mark of 5/10 as
halfway to success rather than halfway to failure
Concept Visualizations of
Computer Programs
Brian d'Auriol
A major issue facing the
programming world today is the quick and efficient understanding of existing
program code by programmers and software engineers. Visualization of concepts inherent in the program code is
proposed as a new mechanism to facilitate program comprehension. The premise of
this research is that program comprehension is primarily based on the reader's
conceptual formation of program code fragments. This paper identifies two novel
visualization models called the Program-Scientific and the Conceptual Crown
Visualization models; and presents preliminary visualization studies based on
understanding programs from data processing, high performance computing and
parallel computing applications.
Commonalities
in the Re-acculturation Process to the University Environment for Adult
Learners and Students with Diverse Backgrounds
Khaled Kevin Deeb, Adriana Cronin
This paper presents challenges
and practical techniques that adult educators must deal and incorporate into
their teaching and curriculum design in order to assist their students in the
successful integration into the classroom environment. There is no such thing
as the typical student in an adult education environment. The unique background of each individual is
as diverse as the south Florida landscape itself. A variety of cultures, races, ethnic and religious backgrounds
make up the population of this University. The Barry University community, for
instance, has been ranked, number one
in campus diversity in the South region, according to the U.S. News and World
Report 2004 Americas Best Colleges (US News, 2003).
This has been partially due to the diversified students backgrounds as well as
Barrys demographic landscape and multi-campus operational structure. The
School of Adult and Continuing Education, in particular, offers degree programs
to adult students at over 13 campuses throughout Florida. These adult learners
vary in ethnicity, race, and academic background, among others. Studies show
that minorities, especially females, are more likely to pursue their education.
Also, classrooms are becoming another form of United Nations in which
instructors should keep in mind the students cultural and educational
differences as s/he prepares and delivers their lectures (Figs. 1..4). Thus, students should receive personal attention from
their professors while building one-on-one relationships that help prepare them
to succeed.
Inquiry-Based Learning by
Students with Disabilities Using RemoteScope:
An Internet-Driven Digital Light Microscope
Bradley
Duerstock, J. Paul Robinson
Physical access to classrooms and
laboratories is important, but active participation of students with
disabilities is paramount for learning. For a comprehensive educational
experience, there needs to be interactions between students with disabilities
and their teacher and classmates, as well as the course material and laboratory
equipment. Inquiry-based learning is recommended as a standard of teaching
science to all students at multiple grade levels. This pedagogical approach
encourages students to actively explore and interact with scientific concepts
and phenomena in order to gain a more thorough understanding. Learning
science is something that students do, not something that is done to them.
(National Research Council, 1996) However, physical
disabilities require us to consider a significantly different approach because
their disabilities prevent many students from taking a traditionally active
part in classroom demonstrations and to perform laboratory experiments
Net-Conferencing as an
e-Learning Tool to Improve Retention Rates on a Mathematics Course Taught by
Distance Learning
J G Dyke, L D Jenkins
Communicating mathematically
by telephone or by correspondence tuition can be extremely difficult. In
addition, attendance at face-to-face tutorials can be difficult for many students
e.g. for those who are geographically isolated or for students with
disabilities. The net-conferencing
project discussed in this paper was undertaken to investigate how new
technologies, in particular a graphics pad used in conjunction with the Net-Meeting
conferencing system, could be used to improve communication between tutor and
student on a distance learning mathematics degree course and to investigate the
hypothesis that this improved communication would lead to higher average marks
and improved retention rates.
Growing the UKs Healthcare
Workforce through e-Learning
Maureen A.
Eby
The Open
University, the UKs open and distance learning university, has invested in the
developments of an e-learning environment to support work base learning initiatives
to increase the UKs healthcare workforce.
This initiative focussed on meeting the UK demand for nurses through the
development of the first work based pre-registration programme. This educational programme is drawing
substantially on the developments within the Open Universitys e-learning
platform. This paper will examine the
development within e-learning that help to support this programme as well as
focus on the educational pedagogy that supports robust and transparent learning
which provides the foundations for lifelong learning.
A Cooperative Human-Robot Learning System using a Virtual
Reality Telerobotic Interface
Yael Edan,
Uri Kartoun, Helman Stern
This paper presents the concept
of a cooperative human-robot learning system for remote robotic operations
using a virtual reality (VR) interface. The case-study task is to empty the
contents of an unknown bag for subsequent scrutiny. The system employs several
state-action policies. A system state is defined as a condition that exists in
the system for a significant period of time and consists of the following
sub-states: 1) the bag which includes a feature set such as its type
(e.g., plastic bag, briefcase, backpack, or suitcase) and its condition
(e.g., open, close, orientation, distortions in bag contour, partial hiding
of a bag, changing of handle lengths); 2) the robot (e.g., gripper
spatial coordinates, home position, idle, performing a task); 3) other
objects (e.g., contents that fell out of the bag, obstructions) and 4) environmental
conditions such as illumination (e.g., day or night). A system
action takes the system to a new state. Action examples include initial
grasping point, lift and shake trajectory, re-arranging the position of a bag
to prepare it for better grasping and enable the system to verify if all the
bag contents have been extracted.
Network
Adaptability in Clusters and Grids
Jeffrey J.
Evans, Seongbok Baik, Joseph Kroculick, Cynthia S. Hood
The acceleration in computational scale to solve problems in emerging computational fields from Nanoscience and Genetics to Astrophysics places increasingly heavy compute and data storage burdens on locally and globally distributed computer systems. We are focusing on the management of these loosely coupled systems (clusters and Grids) which are asked to behave as an increasingly large single entity, repeatably and reliably. Our approach explores several areas and levels, from low level detection and reaction of subsystems to application dynamics, including human factors. These areas are discussed and results from our work to date is presented. New questions to stimulate deeper thought and discussion into requirements understanding are then posed.
A
Collaborative Project for Developing Smart Residences for Aging Populations
Raymond A. Eve, Diane J. Cook,
Sajal Das, Karthik Gopalratnam, Abhishek Roy, Susan Brown Eve,
Kenneth Durand
This paper describes a
collaborative project involving engineering and social science faculty from the
University of Texas at Arlington and the University of North Texas working in
collaboration with a retirement community.
The focus of the collaborative project is a prototype smart house,
located at UTA. To assist the aging populations of post-industrial nations, the
current project goes beyond existing efforts.
It does so by integrating a total system of human factors assessment
through integrated data collection, remote monitoring, sophisticated prediction
algorithms, and advanced data-mining to provide predictive health monitoring
and daily living support for the aged and their caregivers.
The Internet's Role in Societal
Awakening
Jay Fenello
As we transition from an
Industrial Society, to one based on Knowledge and Information, many of our
previous institutions will be found obsolete and irrelevant. Not only will
institutions be impacted, but society as a whole. This paper will focus on the individual's role in, and experience
of, the process.
A Prolog-like Language for the Internet
Ulisses Ferreira
This paper presents a three-valued logic programming language, which permits definitions of clauses under closed-world assumption or without it, due to the presence of a constant (referred to as uu) at the language level. A third truth value is used to provide only one negation, defined here as abstract negation, while Extended Logic Programs adopt two kinds of negation. I present an operational semantics for both propositional and the predicate forms, including variables. The language can be seen as an adaptation of Prolog capable of capturing lack of information. In particular, the language can be viewed as an appropriate compromise solution between logic and a global structure such as the Internet. Little work has been done combining logic with such a platform.
New
Aspects of Software Quality in Components Base Software Engineering
Eva Feuer
Wide spectrum of web services are
available for the internet users. These services range from just reading the
web pages to doing in e-business and technical services. Web services are built
of grouped, reusable software components. The use of component based software
development (CBSD) was assumed to offer many benefits in software engineering,
including reduced time to market, reduced development costs, and improved
productivity on the other hand raises several issues. The components used are
often made by a third-party, sometimes unknown source black-boxes. In order to
take the advantages of component based development, it is very important to
have information about the quality of components. In this paper we describe how
the generic software quality models apply to CBSD and what special attributes
should be introduced for components.
Space, Time, Matter and Force
Peter G. O. Freund
Our understanding of the four
basic concepts of physics: space, time, matter and force, has undergone radical
change in the course of work on unification, beginning with Maxwells
unification of electricity with magnetism in the nineteenth century, all the
way to present day string theory. What started out as four independent concepts,
with space and time postulated and the forms of matter and force arbitrarily
chosen, now appear as different aspects of a rich and novel dynamically
determined geometric structure. I will present these new developments for an
audience of non-physicists.
New Space Technology: 1km Tether
to 100,000km Space Elevator
Hironori A. Fujii
Tether technology is a very old
technology used for human activity in fabric works for clothes, fishing and
hunting, building, and tethering horses and dogs. The tether technology is now
becoming one of new and promising technologies for human space activities as
spacecraft thrusters, power generators, and important elements of space
infrastructures. The present talk
includes some recent works of the speaker on the space tether technology
applied to an aurora experiment using a sounding rocket, a space solar power
satellite and a space elevator for lifting us from the Earth to the Moon.
The Estrogen Replacement Therapy
Brouhana
Judith
S. Gavaler
The controversy about estrogen replacement therapy (ERT) could have been avoided if the epidemiologists had been clever enough to confer with a knowledgeable endocrinologist who would have told them " measure estradiol levels", and avoid "form over substance", also known as intention-to-treat. That one biomedical consult could have nullified the controversy, the subsequent scientific hand-wringing, the waste of immense amounts of better-spent research funds, and the misery of women who have stopped using ERT. The estradiol levels achieved among ERT-treated women vary substantially and thus so do the results of these ill-conceived ERT clinical trials.
Health
Disparities Research
Judith
S. Gavaler
Health Disparities (HD) Research
(a politically-correct term for racial health inequalities) is difficult to do
effectively. First, using census-based sources involves merely organizing
existing data, which cannot permit identification/examination of potential
underlying factors and interactions. Second, meaningful research requires prior
multi-disciplinary thinking. Third, inherent investigator racism and fear must
be quelled, because minority participants will need to be recruited and
communicated with. Fourth, one may learn that HD research is largely another
politically-correct initiative, as little funding is actually available.
However, we few old civil rights activists are managing to learn substantially
about Health Disparities.
E-Psychiatry and the Online
Treatment Paradigm
Mitchell E. Gibson
The delivery of quality mental
health services to isolated and physically challenged populations has long been
a problematic issue in psychiatry. With
the advent of psychiatric service providers via the Internet (e-psychiatry),
this dilemma may now be addressed. However, the primary treatment paradigms
have not been well established and the resolution of issues such as
relatedness, transference, cost, safety, legal issues and efficacy are central
to the success of any effective online therapeutic relationship. In this paper I will examine these core
issues that plague the fledgling field of e-psychiatry. I will also examine the strengths and
weaknesses of several solutions to these problems in the clinical psychiatric
setting.
Tools for Telementoring and
Real-Time Telemedicine in Networks over Satellite
Georgi Graschew, Stefan Rakowsky,
Theo A. Roelofs, Peter M. Schlag
Modern information technologies
allow the realization of simulation, navigation and interactive communication
systems for an improvement of medical diagnosis and therapy. Using a specially
designed communication software (WinVicos) and standard hardware components
various telemedical applications (telementoring, teleconsultation,
teleteaching, etc.) have been enabled via satellite-based networks. Two
telemedical networks have been developed recently: MEDASHIP (Medical Assistance
for Ships) and EMISPHER (Euro-Mediterranean Internet-Satellite Platform for
Health, medical Education and Research) for real-time services for healthcare.
A high-immersive environment for training of surgical interventions is
supported optimally by computer-assisted simulation and visualization and
enables the surgeon to actively take part in the training and to work
collaboratively.
Geometric Methods in Finding
Intersections of Quadratic Equations and Their Applications in Improving GPS
Algorithms
Weiqing Gu
The problem of finding
intersections of a system of quadratic polynomial equations is a classical one.
It has many applications in real world problems, such as in computer aided
geometric design and in robotics. Recently, the author has encountered such
applications in improving GPS algorithms. Current search and rescue satellite
aided tracking systems can take several hours to determine the originating
location of a beacon signal. A new satellite array has been proposed which will
allow for nearly instantaneous detection. This new system calls for a different
set of quadratic equations to be solved in order to determine the beacons
location. In this paper, an elegant geometric method of finding such solutions
is presented. Closed formulas for finding the complete intersections are given.
The geometry of the intersection locus has been analysed systematically.

We will argue that that the
concept of agent autonomy is useful in complex, critically automated systems.
Autonomy is a key feature in trusted as well as autonomic computing. Whereas
autonomic is the self-regulatory property of a computing system,autonomy is a
property of individual computing units and embodies a host of important and
relevant concepts. Autonomous is an observer-centric attribution and can be
exhibited by properly modeling internal reasoning of entities regarding their
autonomy, which at times coincides with the notion of independence. In this talk
we review recent developments in agent autonomy and how this work can
contribute to autonomic computing.
Statistics Education Online: Challenges and Solutions
Erin Hodgess
Statistics education presents special challenges using
distance education. The development of
a fully online business statistics course is described, with emphasis on tools
such as website tutorials and graphics generation. Evidence on the effectiveness of the online course is presented
via analysis of course grades. As an extension
to the online course, an experimental procedure for generating multiple choice
questions for an online test bank is discussed.

technology as a common instrument for communication, mentoring, and
support for teacher educators; (2) how the RE3 project serves as a catalyst
to explore and develop innovative ways to use IBM new web-based tools to
creatively address specific needs of each partner, and achieve results that can
be replicated.
Some Possible but Avoidable
Negative Impacts of Internet on Education and Medical practice
Felix T. Hong
The
positive impacts of the application of Internet on education and medical
practice has been amply documented. A major strength of Internet application
--- the ease of data retrieving from vast sources at remote sites --- also
happens to have potential negative impacts on education and medical practice. A
glut of information tends to overwhelm the users: students and physicians.
Unless a preventive action is implemented early in the course of applications,
the risk of a reciprocal diminution of compression may defeat the purpose of
using machine intelligence to supplement and enhance human cognition. In
particular, excessive reliance on digital information may hamper humans analog
appreciation, thus contributing to unnecessary human errors. Our arguments are
based on new insights into the enigma of human creativity.
Combining
Modeling and Fault Detection in Automated Manufacturing Systems Based on Hybrid
Petri Net
Hu Hong
Automated
manufacturing systems, which is characterized by dynamics, concurrence and
synchronization, is a Hybrid dynamic system involving discrete and continuous
behaviours. The static attribute and the dynamic actions of automated
manufacturing system can be modeled through hybrid Petri net. This paper
describes a hybrid Petri modeling for automated manufacturing systems, based
hybrid Pertri nets, and capable of fault detection. A successful example of
automatic manufacturing system is presented and analysis of the model is given
using VisObjNet in this paper.
Asessment
System to Evaluate the Information Technology Skills of Students - Prepare for Future
Work in Accounting Industry
K.W. Hui,
W.K. Kan
Accounting
has large penetration rate to use of Information Technology in the business
sector. It is well known that computer has the power to process and storage
large amount of data. Therefore, it is more efficient to computerize the
accounting ledgers. Assessment System is to evaluate students' Information
Technology skills in order to prepare them for future work. The Assessment
System can assist teachers to know whether the Information Technology skills
for students are up to the skills for future work in accounting industry. It
can also indicate the weakness of students and thus teachers and students can
make improvement on these areas.
Renewable
Energy Technologies for Poverty Challenges in the Third World Countries
Lubna
Razia Ijaz
Effectively
addressing todays Poverty Challenges, in the third world we must address our
energy needs, which requires acquisition of advanced Renewable Energy
Technologies along with policies that influence economic markets while
advancing the public good through proper energy education and research
facilities. And to develop adequate infrastructure to facilitate the
establishment of renewable energy industries in the developing countries, which
could help solve the energy crisis in the country. Furthermore, increased green
house emission from fossil fuel combustion, dominates the climate change
debate. Green energy laws are being proposed at present for at least 5 percent
electric power generation through renewable energy resources and between 15 to
20 percent in 15 years increasing to 50 to 70 percent in 50 years to combat the
environmental crisis. Therefore, there is an urgent need for Transforming
Global Energy Scenario through renewable energy resources This will help
environment to become friendlier, cleaner and greener. This will also help the
energy sector to sustain energy prices, and ensure availability of clean energy
at all time to all people of the world at large.

displayed images of cell penetration and crystal manipulations.
High
Quality Image Watermarking on the Lowest Wavelet Subband
Sanghyun
Joo, Jin Woo Hong, Jaeho Shin, Hisakazu Kikuchi
In this
paper, we propose a robust blind watermarking that embeds a pseudo-random
binary watermark sequence into the lowest wavelet subband. Although it is known
that the lowest subband embedding cause severe degradation, we overcome the
degradation by employing two techniques. First, watermarks are adaptively
embedded by considering human visual system. Second, watermark embedding is
skipped for some coefficients that cause severe degradation. Owing to these
techniques, a good fidelity and robustness can be obtained simultaneously.
Mobile Telemedicine Super
portable Personal Systems - the Future of the Rural Health Care.
Salikh Kabulov, Alexander Ryzhov,
Vyacheslav Sharov, Anatoly Taran
Rural health care always had and has a main problem - a lack of
qualified specialists who are willing to leave big cities with their promising
opportunities for living and working in small towns and villages. There are no obvious signs of the change
of the situation for better, moreover, in spite of increasing budget to the
rural health care during last years all efforts to improve it became
ineffective. While administrators are
again busy with making decisions concerning new reforms of the rural health
care, it still differs strongly from urban one. More or less effective attempts
have been made in the 80-ies by the start of the use of mobile medical
technologies, for example, mobile CT and mobile MRT. But contribution of
rapidly developing telemedicine in the rural health care is hard to over
evaluate as well.

Manoj
Kumar Kashyap, Amit Kumar, Amit Kumar Yadav, Anjana Kashyap, Richa Kaushik,
Natalia Emelianenko
Most of the metabolic pathways
and their regulation is under the control of more than one gene or in another
word, these pathways are multigenic pathways.Gene microarray is a technique by
which one can identify the different genes involved in particular type of
diseases .A microarray is a tool for analyzing gene expression that consists of
a small membrane or glass slide containing samples of many genes arranged in a
regular pattern. This technique involve steps from preparation of DNA chip
using a chosen target DNA dissolved in a hybridization solution containing a
mixture of fluorescent labeled cDNAs followed by incubation with the DNA Chip
.The bound cDNA detected using a laser technology and data analyze by using the
computational methods.
Unrecognised leep Apnea in Perioperative Patient
Population
Roop
Kaw, J. Golish
The
symptomatology of sleep apnea may be difficult to distinguish from normal
variations in sleep behaviour. Clinical examination carries a sensitivity &
specificity of only 50-60% for definitive diagnosis of sleep apnea even by
experienced sleep physicians1. As such patients with sleep apnea may present
for surgery without a prior diagnosis. Data from the Wisconsin Sleep Cohort
Study estimate that 2% of women & 4% of men in the middle-aged work force
meet the minimal diagnostic criteria for the sleep apnea syndrome.2 Obstructive
sleep apnea is more common in patients presenting for surgery, 1-9% incidence,
although the more severe forms are less common.
Preparing
Graduate Students to Address Children's Need in Challenging Times
Lisa
Kelly-Vance
In my
presentation, I would outline some of the serious issues facing our society and
educational system that must be addressed by a generation of young people who
are capable of confronting these future problems in an intelligent and
humanitarian way. I will provide specific examples about how I approach these
issues from a graduate training perspective.
Action and
Entropy in Complex Systems and Their Role in the Morphogenesis of
Self-Assembling Structures
Ivan R.
Kennedy, Angus Crossan, Harold Geering
The action
resonance theory (ART) allows entropy to be estimated from a systems action, a
material property equivalent to angular momentum, or spin, as well as by
experimental third-law measurements of the total thermal heat capacity, or by
statistical methods. As a corollary,
ART proposes (Kennedy, 2001) that sustainable morphologies in ecosystems
depend on continuous balancing of action exchange forces generated by quanta,
with momenta corresponding to variations in energy diminishing by many orders
of magnitude from nuclear to gravitational states. Such sustainability has profound significance for the
stability of all self-assembling structures in biology and the environment,
with implications for processes such as the folding of newly-engineered
proteins in biotechnology to the vertical redistribution of atmospheric gases
in global climate change. These cross-disciplinary
implications of ART will be discussed.
Focused
Crawling Japanese Scientific Documents
Vitaliy V.
Kluev
According
to several estimations, the amount of data created in the last two years is as
big as the accumulated data in all human history. This exponential growth trend
continues. Finding appropriate
information on the Web is getting more difficult with inefficient tools
currently being used on the net. In
this paper, we advocate a distributed topic specific (focused, niche) approach
to build search engines. We discuss our experience in compiling a large
Japanese document collection of Algorithms. We have found that some of our
heuristics and techniques to crawl the Web have shown positive results.
A New Approach to Analyze Huge Internet and
Telecommunications Data
Victor Korotkikh,
Noel Patson
Huge data
sets associated with telecommunications and Internet systems can be viewed as
digraphs with hundreds of millions of vertices. These huge graphs are
cumbersome to process and difficult to visualize due to the size of computer
displays that are usually of the order of only one million pixels. In this
paper an approach is developed and explored that represents digraphs as 2-D
vectors, which interact to form a 3-D Lipschitz function surface. These surfaces can be efficiently encoded as
binary sequences and thus reduce the amount of memory required to visualize the
structural and geographical nature of the huge digraph data. It is believed
that the approach may assist managers in making decisions and strategic
planning, such as the optimum locations for future infrastructure. The approach
may also pinpoint and predict potential hotspots to assist in the maintenance
and development of networks and the Internet.
Mapping, Programmability and Scalability of Problems for
Quantum Speed-up
E. V. Krishnamurthy
This paper explores the reasons
as to why the quantum paradigm is not so easy to extend to all of the classical
computational algorithms. We also explain the failure of programmability, and
scalability in quantum speed-up . Also due to the presence of quantum entropy,
quantum algorithm cannot obviate the curse of dimensionality encountered in
solving many complex numerical and optimisation problems.
C2G, G2C, and C2C Communication in the Ubiquitous
Information Society
Masaaki Kurosu
Internet for desktops, laptops,
PDAs and cell phones are now growing in number and the variety of
services. In the ubiquitous information
society, people will be able to access to the internet wherever, whenever and
whatever they would like. We conducted
a field survey for local governments and the citizen in terms of what they
would like to communicate with each other in what kind of situation. Based on this survey, we proposed a concept
and created a prototype of Here-It-Is ("Koko-memo" in Japanese)
system. The prototype of this system is
composed of the cell phone with digital camera and GPS function that provides
an opportunity for them to send a multimedia message regarding anything they
found in town. Some may send a request
to the local government for the repairment of the road sign that is difficult
to recognize, and some may send a message that s/he found a good new restaurant
in town. We conducted a feasibility
survey of this system and confirmed its effectiveness.
Planning
in Practice: Action Research in Venezuela
Kusch,
Rebolledo, Ryan
Planning
and carrying out action research is seen by some authors to be described by a
linear or circular process. There are several tasks at hand in this paper. What
brought us together as a group was the desire to organise an action research
event in Venezuela. While our context may seem unusual, this strangeness helps
problematise some of the generic issues planning and carrying through action
research. We hope to take analysis of action research one-step further by
showing that there are parallel processes within the planning for such events,
the events, and in their subsequent analysis. In March 2000, the Collaborative
Action Research (CARN) Network (1) issued a call seeking people experienced in action
research, who might want to help plan and present an action research event for
elementary school science teachers in Venezuela, South America. By the time of
the Winchester Event, JK and CR had made preliminary proposals of possible
activities, without knowing much of the context where the workshop was to take
place. We asked questions about who would participate in the event, and which
purposes would be served by the event that we organised.
Evaluate Students Information
Technology Skill for Project Based Learning through the Use of Web-Based
Information Technology Skill Assessment System
T.S. Lee, W.K. Kan
This paper describes the development of a web-based
Information Technology skill assessment system. The main purpose of this
project was to evaluate students Information Technology skills in order to
prepare them for project-based learning. By the assessment system, teachers can
know whether the Information Technology skills for the students are enough for
their study purpose. It also indicates the weakness of students and thus
teachers can tailor made the learning material for them so that their
Information Technology skills are up to standard for their project based
learning.
Analysis of Social Science Theory
through Computerization of Representations in Formal Logic
Sheldon G. Levy
Social science theory is usually
verbally stated. This lack of formal
representation limits predictions to data and imposes limitation in identifying
contradictions. This contrasts with the
identity between mathematical models and physical science. Muncasters propcalc computer program allows symbolic logic propositions to be
examined for their deductions and consistency.
The authors theory of reduced
alternatives, posits psychological consequences to citizens whose outcomes
are low in institutional settings such as education, income, and status. The result is to increased rather than
decrease support of governmental authority.
The propositions of the theory are stated in symbolic logic and their
consistency and implications examined through propcalc.
Global Optimisation for Optical
Coating Design
Dongguang Li
The optimisation algorithms are
playing a significant role in the field of the optical coating design. Many
advanced local and global optimisation techniques, such as Gradient, Simplex,
Flip-flop, Needle , Genetic and Simulated annealing, have been successfully
applied to optical coating design. Any optimisation algorithm applied to a
particular design problem should firstly address the issue of choosing a
reasonable starting design, which is always a big obstacle to an inexperienced
designer. To find the true global optimised solution for a coating design
problem, we need to solve an array of interlinked multi-dimensional
simultaneous equations. For more than just a few layers, until recently this
has been a very difficult task, requiring the use of a supercomputer and highly
skilled programming. By using the orthogonal Latin Square theory and an
experimental design methodology in a search space reduction process, a Windows
based program has been written that can operate on even a desktop personal
computer. It can find the global optimum design for a 23 layers design using
any dispersive and lossy material within a period of several hours.
Additionally, this methodology (DGL-Optimisation, DGL is the short for D.G. Li)
allows the use of target spectra such as s & p polarisation, with
reflection and transmission simultaneously.
Firearm Identification System
Based on Ballistics Projectile Images
Dongguang Li
Characteristic markings on the
cartridge case and projectile of a fired bullet are created when it is fired.
Over thirty different features within these marks can be distinguished, which
in combination produce a fingerprint for a firearm. By analyzing features
within such a set of firearm fingerprints, it will be possible to identify not
only the type and model of a firearm, but also each every individual weapon as
effectively as human fingerprint identification. A new analytic system based on
fast Fourier transform (FFT) for identifying the projectile specimens by the
line-scan imaging technique is proposed in this paper. Experimental results
show that the proposed system can be used for firearm identification
efficiently and precisely through digitizing and analyzing the fired
projectiles specimens.
MS Windows Based Optical
Thin-film Design Software with DGL Global Optimization
Dongguang Li
The paper describes an innovative
global optimisation algorithm and commercialised optical thin film design software
using the discussed algorithm. The MS Windows software application has been
developed, which shows a great advantage in finding a best optical thin film
optimisation design over other conventional design methods. One real world
design problem is discussed in details.
Ballistics Image Visualisation
and Processing on Internet
Dongguang Li
The cartridge case image database
is a part of the ballistics firearm identification system, Fireball, developed
at Edith Cowan University (ECU) in Australia. Web based tools for querying,
visualising and simple image processing the cartridge case image from the
database have been developed. This paper will give a brief description of this
system and details of these tools.
Performance Comparison of Two
Delay Sensitive Multipath Routing Schemes in Ad Hoc Directional Networks
Yang Li, Hong Man
Applying directional antennas on
ad hoc wireless network has become an attractive research topic because of its
potential for increasing channel capacity through spatial reuse. However
conventional ad hoc routing protocols (e.g. DSR, AODV) based on the shortest
path metric usually suffers long transmission delay and frequent link breakage
over this type of networks. This is caused by a unique feature of directional
transmission commonly known as deafness'. In this paper we introduce a
multipath on-demand distance vector (MODV) routing scheme, which attempts to
explore the advantage of spatial reuse and to reduce per hop medium access
delay due to next-hop deafness.
Spatio-Temporal Web-Based Multimedia Information System
Hervé Martin, Jerôme Gensel
Web and multimedia technologies
enhance possibilities to develop software for managing, displaying and
distributing spatially-referenced information. More and more geographic
information systems (GIS) applications have to integrate both a temporal and a
multimedia dimension. Such softwares are required in various fields such as
E-mobility and risk management. In this paper, we present new trends in Web
cartography both from a formalism point of view and from a technology point of
view. We show how models and languages used in web and multimedia information
systems may be used to model and to navigate across spatio-temporal referenced
multimedia data. Actually, our team is involved in various projects related to
this problematic. We illustrate our presentation with some examples developed
in those projects.

Enhancing Access Dynamics for
Interdisciplinary Research and other Interactions through a New Range of
Simplified University Portals.
Albert E.J. McGill
Victoria University is a dual sector
institution (FE & HE) situated in the west of Melbourne on eleven campus
precincts serving more than 50,000 students within a region of broad ethnical
and cultural diversity. As a relatively
new university, although originating in 1916, new opportunities are being
developed not only to differentiate its activities from its neighbouring
institutions but also to provide an entirely novel approach to client
engagement. An number of institutes are being established, based on proven
research, teaching, training, consultancy and advisory skills that will allow
client issues to be accepted and a holistic range of initiatives to be
developed that deal with those issues completely. The first institutes
established include Biotechnology, Health, Sustainability & Innovation,
Integrated Transport & Logistics and Community Engagement and Policy
Alternatives. This approach will provide a single access portal for clients
from government, industry and community rather than through a complex directory
approach.
Global Monitoring System of a
Site of Communication Satellites and Transfers of the Information in a
Geostationary Orbit
M. Meshkov
The modern
satellites-retransmitters of communication systems using perspective Ku a
range, should be kept in a working point in geostationary orbit (GSO) with
accuracy ± 0,05 degrees and it is better. Ballistic-navigating maintenance of
similar communication satellites is offered to be executed with the help of
precision measuring instruments of the angular coordinates placed on the ground
and allowing to take the bearings of satellites on signals of telemetry to
within 5-8 angular seconds. In Russia the similar monitoring system is realized
by state enterprise "Space communication" for a satellite
communication system and telecasting with use of space vehicles of a series
"Express-AM". The offered global monitoring system of a site of the
communication satellites established in any point GSO, is extremely optimum and
will consist all of three ground stations placed any way enough within the
limits of a ring with breadth up to 500 on north and the south from equator (in
the report possible variants of accommodation of stations are resulted in view
of zones of overlapping and the basic technical and economic parameters of
these stations and systems as a whole).
Conservation and Establishment of
Medical Plants in Backyard Home Gardens in Tanzania
Mkangare M.J.Minja
The majority of plants used in ethnomedical and
ethnoveterinary practice in Tanzania are mainly harvested from the wild. The growing demand for medicinal
plants calls for enhanced conservation strategies.
In order to ensure that representative wild populations of vulnerable
medicinal plant species are conserved, there should be efforts aimed at
establishing sustainable medicinal plants base in the form of backyard home
gardens, to satisfy the health needs of both man and animals. Backyard home
gardens serve as alternative supply sources through cultivation in large enough
quantities and at a low enough prices to compete with prices obtained by
gatherers of wild stocks.
Broadband Infrastructure and
Rural Regional Development: in the County of More & Romsdal, Norway
Judith Molka-Danielsen, Ottar
Ohren, Bjorn Jager
This paper reports on findings of
two surveys conducted in April 2001 and November 2002 on broadband
infrastructure deployment and utilization of ICT services in 38 local
governments of one county in Norway. Services include internal administrative
services for the employees and services to the residents of the communities. We
examine how well actual adoption of services had met with expectations.
Findings show adoption and use was not as pervasive as expected. Our study is
compared to several other regional area studies carried out in Spain. Last, we
discuss how this can be an inhibitor to this area's regional economic
development.
Autonomy for System Assurance
under Evolving Situations
Kinji Mori
The markets have been changing
rapidly and the users preferences are much more difficult to predict. The technologies have been advanced
day-by-day. Under the evolving
situations, the heterogeneous systems are connected and the heterogeneous modes
and requirements coexist in the system.
Then the system is required to keep its operation under these dynamic
situations, that is, the system assurance.
For attaining the assurance, the system design view, technology and key issue
of the autonomy for the assurance are discussed with the real application
systems. These proposed assurance
technologies are shown to be effective in these applications.
Web-Based Information Systems in the Public Sector
Birgit Oberer, Alptekin
Erkollar
In this paper there will be shown
how electronic services within the public sector should be classified, how they
can be developed and how can the provision of these services be supported. To
support the classification of electronic services by the public sector there
has been developed a three-dimensional classification portfolio for electronic
services. Targets of the classification are the evaluation of main features of
procedures and the creation of comparable initiatives. There are two main views
within the schemes: the user-view and the IT-view. Within these views there are
two main features, which can be found in every scheme: User-view: The
online-availability of services; IT-view: The possibility for information
technology based e-government procedures. Using this portfolio analysis you can
redesign and support current public electronic services and evaluate
optimisation potential for these services.
Probing Neural Synchronization in
Psychiatric Disorders
Brian F. O'Donnell, Giri P.
Krishnan, Jennifer Vohs, Marcia Bockbrader, William P. Hetrick, Anantha Shekhar
Neurophysiological evidence
suggests that neural synchronization is integral to integration of information
within the brain. Synchronization of
neural activity at high frequencies (> 30 Hz) is thought to depend on
GABAergic interneurons, which appear to be affected in a variety of brain disorders. Electroencephalographic (EEG) recording
allows non-invasive evaluation of the frequency response of the human brain to
temporally modulated stimulation. We
report findings from a series of studies that show abnormal EEG synchronization
in schizophrenia and bipolar disorder, two severe psychological disorders. These disturbances in neural synchronization
at high temporal frequencies may contribute to disorganized cognition and
behavior, which are common in these mental disorders.
A New Image of the Cochlea and
Hearing
George Offutt
The study of hearing is based
upon the assumption that all sound recognition is the result of the detection
of mechanical stimuli in the cochlea. The foundation of that assumption was
built in part upon a hypothesis that uses a negative argument. When S.S. Stevens
(1937) published his hypothesis on electrical sensitivity there were no known
biological receptors for electrical potentials. He used that observation to
hypothesize that the ear was only sensitive to mechanical stimuli. However, we
now know of many receptors that are sensitive to electrical potentials, but the
assumption remains. An alternate is the electromodel that assumes that the
inner hair cells (IHC) of the cochlea are primarily electroreceptors. Many
areas of auditory research have been investigated using that model and no
conflicts with published data have been found (Offutt, book, 1984). The
concepts in the electromodel have also led to a successful treatment of
tinnitus using subthreshold sound (Frantz and Offutt, ITJ, 2003) and to a proposed
explanation for the symptoms of Menieres disease.
The Information Nervous System
Nosa Omoigui
The explosive growth of digital
information is increasingly impeding knowledge-worker productivity due to
information overload. Online information is virtually doubling every year and
most of that information is unstructured usually in the form of text.
Traditional search engines such as Google have been unable to keep up with the
pace of information growth primarily because they lack the intelligence to understand,
semantically process, mine, infer, connect, and contextually interpret
information in order to transform it to and expose it as knowledge. In this
paper, I introduce an end-to-end system and resulting knowledge medium, the
Information Nervous System that addresses precisely these problems. The system
provides intelligent and dynamic semantic indexing and ranking of information
(without requiring formal semantic markup), along with a semantic user
interface that provides end-users with the flexibility of natural-language
queries (without the limitations thereof), without sacrificing ease-of-use, and
which also empowers users with dynamic knowledge federation, presentation and
discovery for cases where the user might not know what he or she doesnt know
and wouldnt know to ask.
Collaborative Remote Monitoring,
Control and Visualisaton in Mixed Reality Environments over the Internet and
Grid
Milena Radenkovic, Steve Benford
The paper will provide an
overview of e-Science and Grid activities in the UK and give a give a short
evaluation of Open Grid Services Architecture (OGSA). Special focus will be put
on Mixed Reality interdisciplinary initiative that brings together leading
researchers from Computer Science, Engineering and Psychology to research new
technologies that merge physical and digital worlds. A number of projects and
future visions for collaborative remote monitoring, visualisation and control
in Mixed Realities over the Grid in different contexts will be explored in more
detail. The paper will introduce novel common infrastructures for supporting
such projects with particular interest on improved scalability, flexibility and
usability. We argue that our infrastructures and interfaces allow for more
effective synchronous and asynchronous collaboration among geographically
remote scientests and field workers.
Atorvastatin
Inhibits LRP5-Frizzled Mediated Ectopic Bone Formation in the Aortic Valves of
Hyperlipidemic Rabbits
Rajamannan NM, Subramaniam M, Gilchrest A, McConnell JP, Singh RJ, Sebo, MD
TJ,.Stock SR, Spelsberg TC
Calcific aortic valve disease is
the most common indication for aortic valve (AV) replacement in the USA. The
cellular mechanisms are not well known. A known low-density receptor-related
protein (LRP5) plays an essential role in skeletal bone accrual. We
hypothesized that ectopic bone formation in the aortic valve (AV) occurs with
the WNT coreceptor LRP5 and Frizzled regulation in an experimental
hypercholesterolemic Watanabe rabbit model.
Cytomics InFormation Repository
(CIFR): An Internet based Scientific Data Management System
B.
Rajwa, P. Varadharajan, J. Paul Robinson
A critical component for a net of
collaborating high-throughput biological laboratories is efficient information
retrieval and management. Data, protocols, standards and methods management is
an almost overwhelming problem where multiple data input sources and various
types of instrumentation are used. The problem of collaboration management of
individuals or groups working in physically separate environments is not new.
Similar issues are faced by many commercial organizations using contemporary
business models that encompass concepts like remote access to organizational
resources, telecommuting, etc. These enterprise business organizations utilize
a sophisticated database and data-mining technologies linked with a specialized
software packages capable of providing variety of functions including: document
management, knowledge archiving, calendar functionality, personal information
management, and so on. However, the case of biolaboratories is unique and
specific, because of the extreme variety of the stored, organized and retrieved
information. These data include textual data, images, algorithms, protocols,
and a number of proprietary binary formats
Web
Advertising Must Mature With Its Target Audience
John Reisner
Although
early predictions claimed internet advertising had great potential, initial
euphoria was later supplanted by much cynicism and doubt. Some have suggested that recent misgivings indicate
future trouble for companies seeking market penetration through internet
advertising. However, internet
advertisers should correct faulty assumptions about user behaviour and
reexamine how internet advertising investments are evaluated before abandoning
this growing marketplace. Internet
advertising can be worthwhile, but its benefits must be measured using
reasonable expectations and assumptions.
The so-called failure of internet advertising actually reflects faulty
and overly-optimistic assumptions and expectations. By examining these faults, adjusting expectations, and
redesigning the advertising model, the internet can indeed be an effective
advertising medium.
A Human Cytome Project: Reversing
the Analytical Strategy of Medical Eesearch
J.P. Robinson, G. Valet, R. F.
Murphy, A. Tárnok, A. Kriete
Biology is no longer a simple
non-quantitative study in live systems. It has become a complex world of large
scale, high throughput data manipulation environment. The ability to manipulate
gene sequences (Genomics) and identify proteins (proteomics) however is not
adequate to represent the cytome appropriately. New technologies that allow us
to critically evaluate mutliparameter functional states of cellular systems
have stimulated the development of new approaches for the collection of
information with more immediate biological or medical importance. Microscope-
or flow cytometry-based observation techniques have long proved capable of
unlocking molecular mechanisms and have the potential to generate phenotypic,
functional, and molecular information via quantitative assessments of
subcellular, cellular and tissue constructs. However, they have been used
primarily as part of hypothesis driven research and not as part of a systematic
"omics" approach. A human cytome project was recently suggested. Instead of expanding from genes as
elementary information units through the infinite network of highly redundant
molecular pathways to the cell and cell systems level, one can primarily focus
on assembled cells as elementary organizational units of organisms and
molecular consequence of both genotype and environment.
Modulation of a Dog's Internal Organ Function by Selective Stimulation of the Left Vagus Nerve
Janez Rozman
The superficial regions of the
left vagus nerves of a dog were selectively stimulated with 39-electrode spiral
cuffs having thirteen circumferential groups of three electrodes (GTE) to
modulate the function of the innervated internal organs and glands. Under
general anaesthesia, the cuffs were chronically implanted on the nerve at the
neck in two adult Beagle dogs. The regions were stimulated with biphasic,
rectangular and current pulses (2mA, 200ms, 20Hz)
delivered to the group of GTE being close to the region innervating the
specific internal organ or gland. The results showed that GTE No. 9 elicited
the highest influence on the heart function, GTE No. 4 elicited the highest
influence on breathing, GTE No. 1 elicited the highest influence on the
pressure within the bladder, and GTE No. 7 elicited the most acidic gastric
juice within the stomach. It was also shown that GTE No. 10 significantly
modified the endocrine function of the pancreas. Results of this study clearly
demonstrate that internal organs and glands can be selectively stimulated via
the selective stimulation of innervating superficial regions of the autonomous
peripheral nerve.
Rural Americas Access to
Broadband: A Preliminary Assessment of North Dakota and Pennsylvania
Sheila S. Sager, Marsha A. Tate,
Ted Alter, Jeffrey Bridger, Jorge Reina Schement, William Shuffstall
Today, the socioeconomic fate of
rural communities is inextricably linked to the quality and speed of access to
Internet services, and content.
However, a thorough understanding of the resources necessary for communities
to achieve full access to the network is necessary. These resources can be grouped into four determinants of access:
context; connectivity; capability; and, contenthere referred to as the 4Cs
theory. Using data gathered for five
rural counties in Pennsylvania and North Dakota, this paper frames rural
high-speed Internet access in terms of the 4Cs theory. Our analyses suggest
there are significant variations between the two states and among individual
counties. Moreover, in order to sustain
socio-economic success, each of the 4Cs must be considered both individually
and collectively.
M-Learning: 'The Real Thing', or
just a Fizzer?
Graeme Salter
The following paper investigates
the technical perspective of m-learning in relation to the educational
perspective. The paper asks the question - whether or not m-learning is a
viable learning environment for a genuine student learning experience given the
current level of available technology? To do this, the authors present a
summary of the technology and technology providers available that might be able
to support m-learning initiatives. From this summary, conclusions are drawn
regarding areas of technical improvement that would be required in order to
support a truly effective m-learning environment.
E-Learn and New Curricula in Biomedical Engineering
Gad Shani
Medicine has become very
technological. Dr.s offices, clinics and hospital rooms are loaded with
electronic devices where modern sensors are linked to computers which receive
the measured signals from the patient body, store them in memory and perform
data analysis immediately. The new development in electronics and material
science resulted in new, compact, sensitive sensors. The miniaturization of
computers, the ability of built-in large memory in a small volume changed the
shape of the medical clinic. In remote areas the signals are sent via telephone
lines to medical centers for analysis and experts interpretation. Results are
presented in a very clear and understandable manner.
Optimized Concrete Mixtures A
Worldwide Solution
James
M. Shilstone
Aggregates and water on the
earths crust are similar. Cementitious materials meet international
standards. A graphical means whereby
anyone in the world can evaluate local materials and select proportions to make
best use of those materials will be presented. The Coarseness Factor Chart has
been in use over 30 years across North America and 30 other countries. The American Concrete Institute and U.S. public
agencies are including the method in their documents. Profiles of mixtures used
for various project types have been assembled and can be duplicated anywhere in
the world where materials and needs are similar.
Interdisciplinary Research and
Speech Rhythm
Oleg
Skljarov
Speech rhythm is defined as sequence of the «Voiced
segment Unvoiced segment» duration.
After normalising, evolution of the rhythm is described by logistic mapping. Dynamical regimes of the rhythm in both normal
speech (chaotic regime) and stuttering speech (regular regimes) are described.
The causes which change these regimes are established. Results
allow using
the optimal
course
of treatment for
each stutterer individually. Such individual optimum course will allow to avoid
the basic shortcoming in correction of the stuttering group correctional
method. It gave us the possibility for carrying out individual studies with the patients with help of
the Internet.
For the Students, By the Students
A Win-Win Collaborative Project Model on Creating Media-rich Content in the Campus
Alan S. K. Soong, Daniel T. H.
Tan
At the Nanyang Technological
University, the student-led Computer Engineering Club in collaboration with the
Centre for Educational Development initiated a win-win collaborative project on
creating media-rich content using a user-friendly content creation system. Such
processes have typically been very expensive to sustain. The production process
also has a long turn-around time between the event and the availability of the
recording. The project is an example exemplifies how institutes of higher
learning can overcome these challenges: by working hand-in-hand with student
organizations on projects, which benefits students directly. In this project,
the student club was able to initiate a project, which provided meaningful
online learning service to the student population at large for the students,
by the students. The paper describes how the project was implemented
successfully and modeled by other school clubs.
The Written English Self-Efficacy
of Learning Disabled, Gifted, and Mainstream Adolescent Students
Claire D. Spicer
The structure of self-efficacy
has become increasingly important for educators. This pilot study examined the perceived self-efficacy and written
English self-efficacy of adolescent students classified as learning disabled,
gifted and mainstream. Participants in
the pilot program were 24, year 9 students.
Students first wrote a 10-minute essay on my favourite day to identify
their written English ability.
Following the essay, students completed a self-efficacy
questionnaire. To identify student
matches or mismatches between perceived ability and actual ability, the
students essays were compared with their self-efficacy beliefs. Analysis of variance revealed that learning
disabled students had the lowest levels of self-efficacy and lowest writing
ability. Mainstream students had the
highest levels of self-efficacy with higher writing ability. Correlations between students essays and
written English self-efficacy revealed no significant results.
The Regulation of the Response to
Self in the Prevention and Treatment of Disease.
John Stanford, Graham McIntyre, Cynthia Stanford, Oscar
Bottasso
Regulation of the response to
self with bacterial reagents offers a novel mechanism for the prevention and
treatment of many diseases. These range from chronic bacterial, parasitic and
viral infections to allergies, autoimmunities and neoplasms. The reagents are
prepared from a number of aerobic actinomycete genera, and consist of
heat-killed suspensions of whole bacilli. The mode of action is at least
twofold:- 1) An adjuvant effect,
regulating cellular immune responses. 2) Bacterial antigens crossreactive with
tissue antigens of mitochondrial origin. Preliminary results are available from
agricultural, veterinary and human medicine.
Faculty-Mentored Research and Project-Based Teaching
M. H.
N. Tabrizi
This paper concerns the
development of a faculty-mentored research and project-based software
development program, which can be an effective education tool in teaching new
software tools and languages in undergraduate and graduate studies. To
illustrate the effectiveness of this proposed faculty-mentored software
development program, a brief summary of the program along with evidence of the
effectiveness of ad hoc pilot progress are introduced here and the primary
methods are discussed. Evidence suggests that program works effectively when
the projects are designed to serve the interests of the students. Using students to "help" faculty
research or grant activity is not what this program is about. Instead, the
program is designed to place students in charge of the discovery process. Thus,
the students control the extent and duration of the undertaking.
Virtual Worlds, the Grounds of
Subjective Identity and Multi Screen Metaphor
Vitalij L. A. Tatko
To be able to watch an internal function or self-activity of living brain networks we used the ambiguous figures in psychophysics and event-related potentials (ERP) experiments. The results confirmed that decision-making process doesnt finish at the moment of the motor/verbal response. We conclude that the single decision act has no sense from the behavioural or statistical point of view. It psychological sense is proposed to be linked with the necessity of externalization of action in order to make intention clear for consciousness. An alternative explanation may uses the "bifurcation points in consideration of transition from internal to external sunjective world as well as formal and multiple logic representation of information, following by Prigigine's self-organization theory (V. Tatko, Perception, 1988, 17, 3: 399).
WEB Based Education of Robotics
and Mechatronics at the University of Maribor
Martin Terbuc, Suzana Uran,
Andreja Rojko, Karel Jezernik
Rapid development of informatics
technology has brought new ways to the teaching process. Book and personal
contacts are supplemented with electronic documents with moving pictures and
internet connections. So we have access from anywhere, anytime and from any
computer system. The content can be changed simultaneously. We introduce new
media to the study of electrical automation. Internet and World Wide Web are
new means in the teaching. The teaching approach, which is practiced at Institute
of robotics for last few years, is presented. It is shown how the teaching
material is prepared, how the homeworks are issued and the students training
for lab work and projects are presented. Using contemporary methods they get
used of up-to-date technology, which will be used in their profession. The
teaching means based on the new technology will not replace the traditional way
of teaching. However, it will supplement it and improve significantly.
A Strategy for Improving U.S.
Middle School Student Mathematics Word Problem Solving Performance
Valerie L. Thomas
U.S. middle school students have
difficulty understanding and solving mathematics word problems. Their mathematics performance on the Third
International Mathematics and Science Study (TIMMS) is far below their
international peers, and minority students are less likely than high
socioeconomic status (SES) White/Asian students to be exposed to higher-level
mathematics concepts. Research literature
also indicates that when students use both In-School and Out-of-School
knowledge and experiences to create authentic mathematics word problems,
student achievement improves. This researcher developed a Strategy for
improving mathematics problem solving performance and a Professional Development
Model (PDM) to effectively implement
the Strategy.
Quality of Service Requirements
for IP/MPLS Routers
Mehmet Toy
As high quality demanding
services such as VoIP are being offered over IP/MPLS networks, quality of
service requirements for IP/MPLS networks are becoming tighter. Best effort networking is no longer
adequate. Low delay and jitter for
premium traffic in the presence of bursty traffic, and 99.999% availability are
minimum requirements to support new applications. This paper will describe requirements
for IP/MPLS routers to support emerging IP/MPLS network applications. CapEx and OpEx impact of not supporting
these requirements are also explained.
Developing
Cognition Through Science Education
Nicos
Valanides
There is a need to design and implement
educational changes that empower future citizens to satisfy their basic needs
and be productive in a cultural and social environment that will be
increasingly dominated by science and technology. It is, furthermore, of utmost
importance to recognise that science education is an integral part of general
education that has no higher purpose than preparing people to lead personally
fulfilling and responsible lives. The goals of science education that stem form
this recognition go beyond content subject knowledge, or conceptual
understanding of science, and encompass understanding of the nature and
processes of science, as well as social values and responsibility, and the
personal development of the individual in terms of problem-solving and decision-making
capabilities, communication skills, epistemological development, and career
awareness. This framework determines the context of the on-going reform in
science education and dictates a real transformation of the teaching-learning
environment that should be based on constructivistic principles and alternative
evaluation strategies.
Desideratum: Simple Syntax!
André van Meulebrouck
This position paper asserts that
the computer industry suffers needless losses in man-hours and productivity due
to gratuitous complexity. One culprit is complex syntax. The antidote is
parsimonious syntactic constructs so that parsing does not become a science in
and of itself. I propose a two step parsing process. The preprocess phase
translates alternate syntaxes, macros, and other directives into engine
syntax. This allows verifying that alternate syntaxes produce equivalent code.
It is also in the best interests of accuracy, and expedites mechanized code
generation. The LISP s-expression would be the ideal lingua franca syntax for
software engines.
Comprehensive Databases of DNA
Gene Polymorphisms
Anna Vasku
During research work concerning
with associations among gene variations and
disease or some their characteristics, a large necessity of various
databases browsing with different
information content is needed. So far, I was not able to find any database
including all what I usually need: Information about all DNA polymorphisms in
all human genes (not only in coding sequences of the gene), metaanalyses of the
results and all known functional (functional genomic and proteomic)
consequences. Such a database would be very useful for the large professional
community.
Framework
for an Internet-Based National Electoral System: the Philippine Scenario
Al. S.
Vitangcol III
The Internet thrives on the
continuing stream of dramatic improvements in hardware, software, and
communications technologies. Another
important factor driving the growth of the Internet are the applications designed
for it, making information and delivery of services instantly and conveniently
accessible to geographically dispersed individuals. It is changing the way things are done, so to speak. These
dramatic changes are not confined to businesses alone but more so to the
efficient and effective delivery of public services, giving rise to G2C model
and E-Government. According to Deloitte Research [2001], there are six (6)
stages of E-Government, but this paper would center only on Stage 2 Official
two-way transactions between the government and its citizens. This paper
summarizes the related factors for developing local E-Government systems. One
important factor is the localization of existing standards or
internationally accepted websites, requiring a strategy for designing usable
web interfaces that can be accessed and understood by multi cultural
audiences, much more a multilingual society.
Redefining Specific Processes of
the Philippine Judicial System into Internet-Driven Paradigms
Al. S.
Vitangcol III
The Philippine legal industry has
been slow in integrating information technology into its basic operational
processes. The extent and
sophistication of court automation in the Philippine judiciary is at least a
few years behind as compared to their foreign counterparts. This paper focuses
on how existing Internet technologies might not only automate but also
transform the practice of, and access to law.
The Internet offers new and creative solutions to old problems dogging
the Philippine judicial system. It is hoped that the study will consequently
appeal to a very diverse audience of practicing lawyers, civil servants,
members of the judiciary, and fellow academics. Henceforth, the paper focuses
on the sole problem: How could specific
processes of the Philippine judicial system be redefined into Internet-driven
paradigms? The results of the study can be used to develop unifying
theories or models, which can be translated into mature methodologies for the
purpose of improving the administration of laws and ultimately dispensation of
justice in the Philippines.
Stroke in the Computer or Pie in
the Sky: The Need for Advanced Computing and Information Technology in the
Search for the Treatment of Brain Disorders
Dag K.
J. E. von Lubitz
Despite intense bench and
clinical research, the majority of brain disorders cannot be effectively
cured. The complexity of the brain
compounded by the complexity of the involved pathophysiologies result in
continuing failures of clinical trials testing therapeutic approaches that show
high promise in simple models of disease.
Computer-based modeling has been applied to the analysis of other
ultra-complex systems in physics, astronomy, engineering, etc. It is the belief of the author that similar
approach to the pathology of the brain may offer a highly promising approach to
better understanding of the involved processes, their relationships, and,
ultimately to the development of effective and less costly therapeutic
interventions.
Strategies for Distance Learning
Organizations Targeting Information Technology Professionals.
Jelena Vucetic
In the last decade, with rapid
development and deployment of Internet-based applications, distance learning
(DL) has emerged as a new paradigm in various aspects of education, including
the academia, corporate training, certification programs as well as K-12
education. In this paper, we shall focus on the applicability of distance
learning in the graduate education of information technology (IT)
professionals.
Life In Unusual Places
Milton Wainwright, S.
Al-Harbi
Microbes exist in the
stratosphere and ancient, 50 million year old, amber. Did our stratospheric
microbes come from, Earth or space? If from space, are they dangerous; could
they cause modern diseases like SARS? Microbes also occur in 50 million year
old amber. Like the fictional Jurassic
Park, could such ancient life, once we released be dangerous? Such studies may
deliver novel drugs and other chemicals and provide us with a better
understanding of what we are and where we came from.
Developing High Performance
In-Memory Web Database Techniques
Fangju Wang
Web databases have been broadly
used in e-education, e-commerce, and many Web related applications. The
response time in visiting a Web database includes network transmission time and
database search time. With the increase of network speeds, the transmission
time is getting shorter and shorter, and the database search time is no longer
a negligible cost. The in-memory database technique can help reduce database
search time. In this paper, two techniques are presented, which were developed
to build high performance in-memory Web databases. Experimental results are
presented and analysed.
Problems
and Prospects for E-Manufacturing
A.S.White
This paper will review the
current major issues in the implementation of e-manufacturing, particularly the
dynamic aspects. It will examine the
progress in the last few years, drawing out particular issues that need to be
addressed. A set of dynamic models of the way e-manufacture is affected by the
overall system set up by groups of manufacturers will be used to evaluate
general solutions for partial and complete e-based companies. Use will be made of the work by the author
and colleagues to devise rule-based design and internet based control of
machine to illustrate how these developments affect the integrated
e-manufacturing environment.
Geographic Information Sytem
(GIS) Models for Transit Benefits
Fred Laurence Williams
Cervero (1997), Lewis and
Williams (1999), and FTA (2000) reported methods for calculating transit's
economic benefits to passengers and other taxpayers. These methods included
Mogridge intermodal travel time equilibrium tests, econometric analysis,
hedonic analysis, budget audits, and consumer surplus calculations. Currently, on behalf of the U.S. DOT, the
author and his colleagues are exploiting GIS Internet technology to model these
economic benefits in real time--on the fly--for selected polygons. The goal is to generate convenient,
accessible, timely, and low-cost, economic valuations of benefits--as separate
GIS layersusing interoperable local data on property values, transit
performance characteristics, census-based transportation data, State highway
performance data, and other locally generated data. The GIS models are designed to meet the standards under
development for the Federal Geospatial One-Stop data initiative. The author envisages a presentation at the
policy analytical level, which includes a nine-cell public choice benefit
matrix that reflects transit's distinct market niches.
Intelligent Biomedical System of
Regularaties Revealing and an Estimation of Pathomorphologic Fluctuations in
Gaster Mucosa on Computer Morphometry Data
A. Yankovskaya, G. Chernogoruk,
I. Mandel
The urgent necessity of
correlating of the data obtained as a result of a computer morphometry (CM) of
a gaster mucosa (GM) with the histologists expert conclusion made on the basis
of alternative group of features is shown. Intelligent biomedical systems (IBS)
of regularities revealing and an estimation of pathomorphologic fluctuations in
a GM according to CM data are proposed. The IBS is based on matrix knowledge
representation, deep optimizing logical-combinatorial and logical-probabilistic
procedures, test pattern recognizing methods and cognitive means of decision-making
justification oriented on users of various qualifications. A new method of knowledge formation is
proposed. This method and modified algorithm of test pattern recognition allow
expanding fields of medicine investigations and application as well as to
reveal new regularities. The IBS is created on the base of the software tool
IMSLOG realized on the base of C++ classes system in the operation system
Windows 95/98/2000/NT
Transformation of the Solution Results of one Problem in the Solution the
Alternative ones Relates on Expert Conclusion: A New Paradigm of an Intelligent
Test Pattern Recognition System
A. Yankovskaya
It is shown importance of connection of various parameters received on the basis of measurements with the commonly accepted parameters, determined by experts on other characteristics. Transformation of the solution results of one problem in the solution of the alternative ones related on expert conclusion is a new paradigm of intelligent test pattern recognition system. It will allow revealing regularities in the data of each of the alternative problems, to define interconnection (cross connections) between components of the problem area (including an information component of these problems) and to realize possibility of decision-making on information component of each of the problems. The implementation of the transformation idea is proposed by modification of the test algorithms of pattern recognition and their realization in the intelligent system. The transformation idea of the problems solution is connected with practical necessity taking place in the field of medicine, management, psychology, education.
The Innovation System of
Knowledge Based Construction Management
Wang Yingluo
The innovation of knowledge based
construction management not only meets the demand of deeper reforms and
economic growth model change, but also is the important symbol of the
construction managements new stage. Knowledge has becoming the key element of
the technology and economic activity. The knowledge transfer is the base of
knowledge management. Knowledge management is the process to recognize
knowledge, acquire knowledge and apply knowledge. With appropriate organization
structure and business process design, organizational culture cultivation and
the support technology of modern communications, knowledge management will
build the environment and incentive mechanism, which speeds knowledge
innovation, knowledge exchanging, knowledge learning, and knowledge
application. It is important to fulfill effective knowledge management during
the process of organizational innovation and organizational leaning. Knowledge
network and sharing knowledge base is the new technology platform of knowledge
innovation and decision support system.
Back to the Future: Java, Stack
Machines and Instruction Level Parallelism
C K Yuen
After
being neglected for several decades, some revival of interest in stack
architectures is occurring because of the wide use of Java bytecode. Stack
programs may be mapped into register programs using a simple virtual register
scheme [1][2][3], with extraction of underlying instruction level parallelism,
containing use-once register contents achieving true dependences free of WAW
and WAR hazards. The resulting code may be executed using various hardware
designs, whether based on reservation stations, reorder buffer or EPIC type
register files. However, several problems need to be solved: (a) Branch prediction: the tag stack used in
the register renaming scheme must be saved during branch prediction so that it
may be restored to its original condition in case of a prediction failure; (b)
Value reuse: values that are repeatedly used in subsequent computation need to
be retaied in register/reorder buffer to avoid repeated loading from cache or memory;
(c) Instruction folding: Recognition of a set of stack instructions that
collectively correspond to a single arithmetic instruction; (d) Cache Load misses: Instructions delayed
by missing operands may need to be shunted out of execution pipelines and
re-inserted subsequently.

TV is Dead Long Live the WEB
(SSGRR-2000)
Harold
Kroto, Nobel Leaurate, University of Sussex, UK
Science,
Engineering and Technology are as vital to our intellectual and cultural
development (particularly our
childrens) as they are to our training to get along in the Modern World. Some efforts to redress the problems
involved in the general Public awareness and understanding of science and
engineering (PAUSE) issues are being initiated via the Vega Science Trust
(www.vega.org.uk), which aims to take advantage of the revolution in TV and
Internet communications technology to improve matters. The best scientists and science
communicators are being recorded and the programmes are being broadcast on
BBC-TV and the Internet. Furthermore School/University outreach programmes are
being developed and Vega is piloting ways in which members of the Science,
Engineering and Technology (SET) community can, as individuals and groups, make
important contributions. Excerpts from SET programmes will be presented. These
efforts present a perspective on SET which places the cultural factors in the
foreground and focuses on the intrinsic charisma of science which is hidden
from many. It is now cruical that the society in general and the scientific
community in particular accept that serious problems are involved in communicating
science and the Internet is set to play a major role. Before the invention of the printing press there was only one
book in the west the bible and it was hand-written by monks. After the
invention the printing press book writing and reading was democratized and
this was truly the beginning of general education. In a similar way the birth
of the Internet has democratized broadcasting
the broadcasting channels no longer control the dissemination of
recorded material individuals and groups of individuals can now do it
themselves and so the Internet has enabled broadcasting to fulfill the promise
it has always had to be a superb educational medium.

The Next Generation of IP Flow
Routing (SSGRR-2003)
Lawrence
G. Roberts, Father of the Internet, USA
For
the last 33 years IP routers have not changed, they still support only best
effort traffic. However, the bandwidth available to people has been increasing
rapidly with the advent of broadband access. The result is that many new
services are now desired that require far better QoS than best effort IP can
support. Also, with broadband, the problem of controlling the total usage and
carrier expense has become important. Thus, it has become critical to improve
both the delay performance and the control of bandwidth for IP service, much as
was accomplished in ATM. Also, call rejection for high bandwidth streaming
services like video is required instead of random discards if quality is to be
maintained. All these problems can be solved with no change to TCP/IP by
routing flows rather than packets. This requires keeping some state information
for the duration of the flow, but this information can be captured on the fly
as the first packet goes by. This permits an IP flow router to achieve all the
capabilities of an ATM switch, but without the call setup delay and at a lower
cost than a conventional IP router.
