|A Cost-Effective Approach for Migrating Enterprise Electronic Mail Systems|
Emmanuel Omojokun, Adeyemi A Adekoya, Ephrem Eyob
Electronic mail (E-mail) is one of the most utilized application
software systems in modern-day organizations. The major
messaging application programs used in the enterprise are IBM
Lotus Notes also known as Domino, Microsoft Exchange
Servers, and Novel GroupWise. For various reasons – such as
high cost of maintenance, undeliverable e-mail issue and loss of
attachments, companies find it necessary to either migrate to
newer versions of their messaging software or to an entirely
different software. In either case, the process must be carefully
planned, well designed and properly implemented to avoid
disaster. In this paper, we present a cost-effective approach for
migrating a particular messaging software. The approach was
implemented and tested for the migration of GroupWise 5.5 to
Exchange Server 2003. We present our success story and
lessons learned from the case. A six-week and one-year post
migration system-audits indicated that the organization derived
several benefits including significant cost savings as a result of
this particular approach. Chief information/technology officers
and e-mail administrators will benefit immensely from the “best
practice” strategy hereby presented.
A Fuzzy Spatial Querying Model for Improving Apartment Web Services
An apartment web service is a web site intended to provide
online services to the residents. With the availability of global
positioning systems and the development of new technologies,
the access of geo-spatial information has drawn great attention
for information retrieves. This research is focused on
developing an online service for an apartment to provide geospatial
information. In this paper, a fuzzy spatial querying
model under uncertainty is used to improve spatial querying.
An inexact inferring with the certainty factor is investigated.
An online spatial database for an apartment is implemented by
utilizing PHP with MySQL database. Demonstration shows
that the system can provide visitors with the amount of
significant geo-spatial information about the apartment.
Moreover, fuzziness and uncertainty are mainly concerned.
Querying examples are provided.
A Malaysian Vehicle License Plate Localization and Recognition System
Ganapathy Velappa, Dennis LUI Wen Lik
Technological intelligence is a highly sought after commodity
even in traffic-based systems. These intelligent systems do not
only help in traffic monitoring but also in commuter safety, law
enforcement and commercial applications. In this paper, a license
plate localization and recognition system for vehicles in Malaysia
is proposed. This system is developed based on digital images and
can be easily applied to commercial car park systems for the use
of documenting access of parking services, secure usage of
parking houses and also to prevent car theft issues. The proposed
license plate localization algorithm is based on a combination of
morphological processes with a modified Hough Transform
approach and the recognition of the license plates is achieved by
the implementation of the feed-forward backpropagation artificial
neural network. Experimental results show an average of 95%
successful license plate localization and recognition in a total of
589 images captured from a complex outdoor environment.
Combining Capability Assessment and Value Engineering: a New Two-dimensional Method for Software Process Improvement
During the last decades software process improvement (SPI) has been recognized as a usable possibility to increase the quality of software development. Implemented SPI investments have often indicated increased process capabilities as well. Recently more attention has been focused on the costs of SPI as well as on the cost-effectiveness and productivity of software development, although the roots of economic-driven software engineering originate from the very early days of software engineering research.
This research combines Value Engineering and capability assessment into usable new method in order to better respond to the challenges that cost-effectiveness and productivity has brought to software companies. This is done in part by defining the concepts of value, worth and cost and in part by defining the Value Engineering process and different enhancements it has seen to offer to software assessment.
The practical industrial cases show that proposed two-dimensional method works in practise and is useful to assessed companies.
Identification and Position Control of Marine Helm using Artificial Neural Network Neural Network
Hui ZHU, Yannian Rui
If nonlinearities such as saturation of the amplifier gain and motor torque, gear backlash, and shaft compliances- just to name a few - are considered in the position control system of marine helm, traditional control methods are no longer sufficient to be used to improve the performance of the system. In this paper an alternative approach to traditional control methods - a neural network reference controller - is proposed to establish an adaptive control of the position of the marine helm to achieve the controlled variable at the command position. This neural network controller comprises of two neural networks. One is the plant model network used to identify the nonlinear system and the other the controller network used to control the output to follow the reference model. The experimental results demonstrate that this adaptive neural network reference controller has much better control performance than is obtained with traditional controllers.
ITS Multi-path Communications Access Decision Scheme
Miroslav Svitek, Tomas Zelinka
Intelligent Transport Systems (ITS) require widely spread and
guarantied quality communications services. Method of ITS
decomposition to set of subsystems and quantification of
communications subsystems parameters is introduced. Due to
typical complexity of the IST solution and mobility as the
typical system elements property idea of communications
systems with multipath multivendor structures is adopted.
Resolution of seamless switching within a set of available
wireless access solutions is presented. CALM based system or
specifically designed and configured L3/L2 switching can be
relevant solution for multi-path access communication system.
These systems meet requirements of the seamless secure
communications functionality within even extensive cluster of
moving objects. Competent decision processes based on
precisely quantified system requirements and each performance
indicator tolerance range must be implemented to keep service
up and running with no influence of continuously changing
conditions in time and served space.
Method of different paths service quality evaluation and
selection of the best possible active communications access path
is introduced. Proposed approach is based on Kalman filtering,
which separates reasonable part of noise and also allows
prediction of the individual parameters near future behavior.
Presented classification algorithm applied on filtered measured
data combined with deterministic parameters is trained using
training data, i.e. combination of parameters vectors line and
relevant decisions. Quality of classification is dependent on the
size and quality of the training sets.
This method is studied within projects e-Ident, DOTEK and
SRATVU which are elaborating results of project CAMNA.

Topology Optimization of Structure Using Differential Evolution
Chun-Yin Wu, Ko-Ying Tseng
The population-based evolutionary algorithms have emerged as
powerful mechanism for finding optimum solutions of complex
optimization problems. A promising new evolutionary
algorithm, differential evolution, has garnered significant
attention in the engineering optimization research. Differential
evolution has the advantage of incorporating a relatively simple
and efficient form of mutation and crossover. This paper aims
at introducing differential evolution as an alternative approach
for topology optimization of truss and continuous structure
with stress and displacement constraints. In comparison the
results with other studies, it shows that differential evolution
algorithms are very effective and efficient in solving topology
optimization problem of structure.
|Using Agents for a Participatory Collaborative Media Sharing Experience|
Luigi Benedicenti, Songsiri Srisawangrat
This paper describes the architecture of an agent-based
music service that generates dynamic playlists based on
suggestions from multiple users. The system employs a
number of agents capable of autonomy, mobility,
scalability, collaboration and platform independence. In
the system, agents are classified into two groups:
requesters and music service team. Requesters work on
behalf of their users, and bring music suggestions from
the users to a DJ agent (DJ) which is part of the service
team. The DJ has a reasoning component responsible for
music selection and negotiation.
Music selection is the result of negotiation among agents
in sealed-bid auctions. The bidding strategy is specified
by users. The amount of a bid implies the value of a song
for a specific user; the DJ will evaluate this amount to
determine the winner of the auction, whose song will be
placed on the playlist. All agents interact with each other
using an interaction/negotiation protocol, through agent
A proof of concept implementation of this architecture
shows that agents in the A-DJ system automatically
perform tasks and collaborate with each other under the
proposed protocol. The implementation appears to be
scalable up to approximately 800 customers on a generalpurpose
Using Fuzzy SOM Strategy for Satellite Image Retrieval and Information Mining
Yo-Ping Huang, Tsun-Wei Chang, Li-Jen Kao, Frode-Eika Sandnes
This paper proposes an efficient satellite image retrieval and knowledge discovery model. The strategy comprises two major parts. First, a computational algorithm is used for off-line satellite image feature extraction, image data representation and image retrieval. Low level features are automatically extracted from the segmented regions of satellite images. A self-organization feature map is used to construct a two-layer satellite image concept hierarchy. The events are stored in one layer and the corresponding feature vectors are categorized in the other layer. Second, a user friendly interface is provided that retrieves images of interest and mines useful information based on the events in the concept hierarchy. The proposed system is evaluated with prominent features such as typhoons or high-pressure masses.

Adolfo Crespo Marquez, Benoit Iung
Within the era of e-manufacturing and e-business,
e-maintenance provides the opportunity for a new
maintenance generation. E-maintenance integrates
existing telemaintenance principles, with web-services
and modern e-collaboration principles. Collaboration
allows not only to share and exchange information but
also knowledge and (e)-intelligence.
This paper outlines the basic capabilities provided
by e-maintenance to companies as well as describes
emerging challenges to benefit from these new
operational improvement opportunities
Online Community Interaction - Revolution or Revulsion?
Marketing writers' assertion that online communities are the
future for organisations may be misguided, although
peer-to-peer networks are certainly the future for consumers.
Brands have experienced ‘consumer revulsion’ at their
poorly-planned attempts to enter online communities to interact
The Internet has facilitated a revolution amongst consumers,
providing a medium for online communities to thrive. Source
credibility is paramount and Internet users are being selective
with exactly whose message they are willing to accept, absorb
and ultimately, allow to influence their buying decisions.
The primary objective of this research is to undertake an
exploratory investigation into the dynamics of online
communities and how membership influences the buying
decision for consumers of genre novels.
Through the process of online focus groups and the completion
of online questionnaires, data on the dynamics of online
relationships between consumers and authors, the buying habits
of consumers and the acceptance of online word-of-mouth
(WOM) were extracted and analysed.
This research demonstrates that the dynamics of online
communities are highly complex and in no way inferior or less
fulfilling than real-life relationships and that the influence of
online relationships on our buying decisions have no less impact
than real-life encounters.
New Architecture of Optical Interconnect for High-Speed Optical Computerized Data Networks (Nonlinear Response)
El-Sayed A. El-Badawy, Farag Z. El-Halafawy, Hamdy A. Kelash, Ashraf M. Abou-Tabl
Although research into the use of optics in computers
has increased in the last and current decades, the fact
remains that electronics is still superior to optics in
almost every way. Research into the use of optics at this
stage mirrors the research into electronics after the 2nd
World War. The advantages of using fiber optics over
wiring are the same as the argument for using optics
over electronics in computers. Even through totally
optical computers are now a reality, computers that
combine both electronics and optics, electro-optic
hybrids, have been in use for some time.
In the present paper, architecture of optical interconnect
is built up on the bases of four Vertical-Cavity Surface-
Emitting Laser Diodes (VCSELD) and two optical links
where thermal effects of both the diodes and the links
are included. Nonlinear relations are correlated to
investigate the power-current and the voltage-current
dependences of the four devices. The good performance
(high speed) of the interconnect is deeply and
parametrically investigated under wide ranges of the
affecting parameters. The high speed performance is
processed through three different effects, namely the
device 3-dB bandwidth, the link dispersion
characteristics, and the transmitted bit rate (soliton).
Eight combinations are investigated; each possesses its
own characteristics. The best architecture is the one
composed of VCSELD that operates at 850 nm and the
silica fiber whatever the operating set of causes. This
combination possesses the largest device 3-dB
bandwidth, the largest link bandwidth and the largest
soliton transmitted bit rate. The increase of the ambient
temperature reduces the high-speed performance of the
Applying Service-Orientation Through a Reference Architecture
Helge Hofmeister, Guido Wirtz
This article investigates the application of the service-oriented
architectural style in the context of large organizations. It
introduces an architectural reference framework that allows for
a business process-centered development of composite applications.
The framework groups artifacts of similar abstraction
levels as well as concerns at five distinguished layers. This way,
the service-oriented principles of abstraction and autonomy
can be respected when designing applications. The layers also
correspond to phases of a design methodology and cover the
aspects of composite applications from process-centered orchestration,
over transactional coordination to data transformation
and connectivity. Based on the framework this article shows
as well how an integration design methodology can be used
to leverage the application systems in the context of a given
Trickster Fiddles with Informatics: The Social Impact of Technological Marketing Schemes
M Louise Ripley, Beverly J. Davis
“Information is power if and only if you have the
knowledge to know what it means, the will to use it, the
ability to apply it, and access to a channel of
communication” . We see this in current fields of
research as varied as Marketing, Philosophy, and
Communications Studies, and in current issues about who
owns and controls technology. But a character from a far
older tradition helps explain many problems in society
today with technology: Trickster, the mythical character
who confuses fact with fiction, makes good use of
Technoism, a term coined by Davis  in 1999 to denote
suppressed skepticism and blind compliance with the
chaotic and uncontrolled progression of technology in our
lives that leads to a dangerous split between the “haves”
and “have-nots” of the technology world. This paper will
discuss the use of Technoism to give the public and users
of technology a false sense of power and control over
their lives when in fact they are being duped into a
financially motivated campaign of consumer exploitation.
The paper makes some recommendations for establishing
a conscience in the use of technology.
