Steganography is a form of security technique through obscurity; the science and art of hiding the existence of a message between sender and intended recipient. Steganography has been used to hide secret messages in various types of files, including digital images, audio and video. The three most important parameters for audio steganography are(More)
—This paper proposes a model for fuzzy temporal knowledge representation and reasoning. It includes the frameworks that incorporate fuzziness with temporal intervals, representation of the knowledge and reasoning qualitatively and quantitatively. An interval-based fuzzy membership representation is defined as an extension to the precise temporal interval.(More)

A key event in the domestication and breeding of the oil palm, Elaeis guineensis, was loss of the thick coconut-like shell surrounding the kernel. Modern E. guineensis has three fruit forms, dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), a hybrid between dura and pisifera 1–4. The pisifera palm is usually female-sterile but the(More)

Research into the environmental effect of greenhouse emissions is now intense. One of the sources contributing to the effect is boil-off gas (BOG) flaring into the atmosphere. BOG formation is caused by heat leakage from the liquefied natural gas (LNG) storage tank. Heat leakages are determined by the effectiveness of heat thermal transmittance of the(More)
This study examines the relationships between leadership character, competencies and commitment on student leadership behaviour. A regression analysis is used to examine the relation among selected variables. The study was conducted among final year business school students in a university in Malaysia who are conducting their final year managerial projects.(More)
Implementing Ad hoc networks are becoming very prevalent during recent years. Security is the most important issue for developing mobile ad hoc networks (MANETs). They expose to various kinds of attacks because of their unique nature in which every node can easily join to network or leave it. Black hole attack is the most probable attack in MANET. In this(More)
The study examines the effects of board process and managerial ownership on company performance of Malaysian public listed companies. Unlike traditional governance models that emphasize on board structure, this study focuses on board process. Two types of data are used; a survey to Malaysian directors and company annual reports. In total, 175 companies(More)
