ABSTRACT FULL TEXT
Giving the right information to the right person at the right time is one of the main factors contributing to the success of e-commerce applications. Existing applications of active views to e-commerce mostly generate application views based on user roles such as customers and vendors, so they cannot completely serve one-to-one marketing. Furthermore, the data controlled by the existing applications is limited to those retrieved from databases, but does not include other web contents such as pictures, descriptive information and hyperlinks. In addition, the integration of active views to existing e-commerce applications still presents some difficulties in tackling heterogenity. This work presents a model of the Active View Agents System (AVAS), based on a co-performance model of multi-agents, to resolve these problems.
 
Keywords: Multi-agent systems, electronic commerce, XML, active rules, active views.

ABSTRACT FULL TEXT
This paper describes the implementation of a multiplierless 1-D DCT which is also applicable to 2-D computation. The key idea is based on the binary DCT of which multipliers are replaced by lifting parameters that essentially are shifts and adds. For lower power applications and smaller hardware size, a bit-serial architecture was invoked in the implementation of such an algorithm. Varying data word length, MSE obtained from our approach and some similar algorithms are also investigated and reported.
 
Keywords: DCT, multiplierless DCT, binDCT, VLSI, image coding.

ABSTRACT FULL TEXT
This paper describes research on measurement of end-user computing sophistication in small-medium enterprises. It aims to define and identify an objective measure for EUC Sophistication that can be used by SMEs to assess the extent they are capable of developing their own applications. Measurement for EUC Sophistication was formulated using 3 dimensions of End-User Sophistication, Usage Sophistication and Application Sophistication that form the EUC Sophistication constructs. Using data from an EUC survey study, an instrument was developed to measure EUC Sophistication Index based on sophistication constructs. Stepwise regression analysis was used to predict measurement variables based on data points from the survey using the sophistication index as the dependent variable. Results show that the constructs were valid measurement for EUC Sophistication and among the EUC applications found to be significant are word processing applications, accounts/finance, spreadsheet applications, sales/purchase order, personnel, inventory control, customer, telecommunication, database and decision model.
 
Keywords: User-develop application, end-user development, sophistication index, end-user sophistication, usage sophistication and application sophistication.

 
RECONSTRUCTION OF VIRTUAL ENVIRONMENT USING CAD-VR APPROACH

Faculty of Information Technology, Universiti Utara Malaysia, 06010 Sintok, Kedah
 
ABSTRACT FULL TEXT
Virtual environment should be able to replicate real environment as realistically as possible. This paper proposes a design framework for constructing virtual environments using Computer-Aided Design (CAD) and Virtual Reality (VR) packages, or in short, the CAD-VR approach. This paper discusses the technical issues involved based on the experience in developing two prototype models of the Universiti Utara Malaysia Sports Complex and the Sultanah Bahiyah Library. The benchmark of the development is the compatibility of the three dimensional (3D) CAD models with VR packages. The CAD modelling issues that have been encountered throughout the development stages are also discussed for future guidelines.
Keywords: Virtual reality, virtual environment, computer-aided design, design framework, modelling issues.
 

 
SMART CARDS AND THE FINGERPRINT: A FRAMEWORK FOR USER IDENTIFICATION AND AUTHENTICATION

ABSTRACT FULL TEXT
Access control has been a great concern in this Information and Communication Technology (ICT) era. The need to control access to certain information and resources has been taken seriously by the ICT community. This research believes that no single security method, algorithm, key or procedure is entirely secure. Hence, a combination of multiple security components is mandatory to provide a high level of protection against fraud and other threats. This research combines two security components, which are the smart card and fingerprint recognition. It looks into the vulnerabilities of magnetic-stripe cards and Personal Identification Numbers (PIN) or passwords widely used in systems today. As a result, the research proposes a framework for user identification and authentication in automatic-teller-machine (ATM) systems using fingerprints and smart cards as opposed to the PIN and magnetic-stripe cards.
 
Keywords: Smart cards, the fingerprint, automatic-teller-machine (ATM), identification and authentication (I&A).
 

 
THE VIRTUAL CHEMISTRY LAB (VC-L): VIRTUAL REALITY AS A LEARNING TOOL FOR MALAYSIA’S SECONDARY SCHOOL

ABSTRACT FULL TEXT
Virtual reality (VR) and its related technologies have paved the way to new opportunities that can be applied to improve current practices and processes in a variety of fields, including education. This research paper presents the ‘Virtual Chemistry Lab’ (VC-L). The motivation for the research is the current challenges faced by students to learn and understand, and also by educators to teach chemistry using conventional and traditional means. The VC-L proposes a new method to assist current teaching practices. In supporting the VC-L proposal, issues such as cost, materials and time were among the elements studied and taken into consideration.
The steps engaged to accomplish the research objectives were: elementary research methodologies, preliminary studies that primarily concentrated on gathering information, prototype software application design and development, information analysis and documentation.
The WildTangent Web Driver and Autodesk 3D Studio MAX were the software development tools used to design and develop the prototype application.
 
Keywords: Chemistry, education, virtual lab, virtual reality, web-based, wildtangent.
