This paper focuses on a new framework for an Intelligent Environment to respond intelligently to persons being in a ubiquitous computing environment. The framework contains 1. context notations to have a three-key-predicate relations (location, activity and response awareness), 2. taxonomy of the context aware computing in responding to user activi

The past decade has seen a rapid development of many applications in the field of pervasive or ubiquitous computing. This is made possible by rapid development in mobile and handheld devices. Due to this widespread usage however, localization and positioning systems, especially indoor, have become increasingly important for resources management. Th

An approach to develop the FPGA of a flexible key RSA encryption engine that can be used as a standard device in the secured communication system is presented. The VHDL modeling of this RSA encryption engine has the unique characteristics of supporting multiple key sizes, thus can easily be fit into the systems that require different levels of secu

Since the advent of peer-to-peer (P2P) services and applications,they have kept on growing in popularity and more and more people are using them as time progresses. Currently P2P traffic occupies a significant fraction of nearly 70% internet traffic. With the traffic demand for P2P applications being the highest, the ISPs are facing problems to han

When the Internet is mentioned it is often assumed that users know how to search formaterials. Many though experience difficulties in searching for relevant materials. One of the reasons for this is the lack of knowledge on how to search effectively for information. This paper will discuss ways of searching materials using the advanced search facil

This study evaluate the performance of ultrafiltration UF membrane system in the treatment of biologically treated palm oil mill effluent (POME) by varying the effects of transmembrane pressure and using different molecular weight cut-off (MWCO). Flat sheet polyethersulfone (PES) ultrafiltration membrane of molecular weight cut-off (MWCO) 1 kDa and

In biomedical signal processing, the aim is to extract clinically, biochemically or pharmaceutically relevant information in order to enable an improved medical diagnosis. All living things, from cells to organism, deliver signals of biological origin. Such signals can be electric, mechanical, or chemical. All such signals can be of interest for di

This study aims to determine the phylogenetic relationship between Holothuria leucospilota (Echinodermata: Holothuroidea) from Malaysia and other Holothuria species using partial sequences of cytochrome c oxidase I (COI) mitochondrial DNA (mtDNA) gene. Holothuria (Mertensiothuria) leucospilota (Brandt, 1835) or locally known as bat puntil is curren

Discovery of new anticancer drugs is a daunting task confronting the scientists for a long time. Computer aided methods can provide important insights in this direction. In this work we have investigated the anticancer activity of aliphatic nitrosoureas using quantum chemical quantitative structure activity relationship (qcQSAR) approach. In this m

This study investigates the ethical awareness of computer use among undergraduate computer science students at two public Malaysian universities. One hundred and fifty-nine students were asked to evaluate the code of ethics pertaining to computer ethics. A comparison of undergraduate computer science students between two public universities was don
