Smart antenna system is a promising technology to provide higher capacity with more reliability. Adaptive beam forming capability is very significant in smart antenna systems. Maximum Signal-to-Interference Ratio (MaxSIR) and Minimum Mean Square Error (MMSE) beamforming algorithms were investigated using 16 elements linear array antenna. Both algor

We report the dependence of growth yield of single-walled carbon nanotubes (SWNTs) on heat-treatment time and catalyst film thickness by the alcohol catalytic chemical vapor deposition method. Three types of heat-treatment, synthesis of 30 min, synthesis of 30 min after annealing of 30 min, and synthesis of 60 min, were investigated. Thickness of C

This article briefly looked at the socio-politico-economic context of ancient Chinese,Greeks, Medieval Europe, the Muslims during the Medieval period and Postmodernism. The political thought of Confucius, Plato, St. Augustine, al-Farabi were surveyed in order to put into perspective the philosophy of higher education from 5th century BC to the 21st

Employee motivation is crucial for organizations to attain competitive advantage in the marketplace. Over the decades, industrial psychologists have developed theories that are purported to help organizational managers to motivate their employees. Employee motivation is also proved to be influenced by the local/national culture. In order to know th

Forty-six bacterial strains were isolated from nine different sources in four treatment plants namely IndahWater Konsortium (IWK)sewage treatment plant (STP), International Islamic University Malaysia (IIUM) wastewater treatment plant-1,-2 and -3 to evaluate the bioconversion process in terms of efficient biodegradation and bioseparation. The bacte

Microbial surface active agents (biosurfactant) have recently been recognized as important microbial products with properties applicable in a number of industries and processes. Being capable of lowering surface- and interfacial-tension, biosurfactants are today thought to be efficient replacers and possible enhancer of chemically synthesized surfa

A novel method to assess the complex Education process has been devised. The technique involves the quantification of Learning Outcome, which has hitherto been largely subjective and cumbersome despite the technological advance in learning and teaching aids. The new technique presents an objective assessment in a mathematical form. The approach is

Solid state bioconversion (SSB) of rice straw for bioethanol production by the compatible mixed culture of Saccharomyces cerevisiae, Trichoderma harzianum, and Phanerocheate chrysosporium was carried out in the laboratory. Design of the experiment and statistical analysis for optimization of bioethanol production was done using statistical software

A digital real time auto tracking robotic system is designed and analyzed. The tracking is based on passive detection using live TV imaging. The target coordinates are determined by an image processing technique and non-linear prediction algorithm. The control signals derived from the video signal set the azimuth ? and elevation f of the camera pos

This work investigated the optimisation of the fermented culture medium for maximisation of rhamnolipids production produced by Pseudomonas aeruginosa 181 using Response Surface Modeling (RSM). A two full factorial central composite experimental design was used in the design of experiments and in the analysis of results. This procedure limited the
