Cognitive Radio (CR) has been proposed as a promising technology to solve the problem of radio spectrum shortage and spectrum underutilization. In Cognitive Radio Ad Hoc Networks (CRAHNs), which operate without centralized infrastructure support, the data routing is one of the most important issues to be taken into account and requires more studies

This research studies the application of hybrid algorithms for predicting the prices of crude oil. Brent crude oil price data and hybrid intelligent algorithm (time delay neural network, probabilistic neural network, and fuzzy logic) were used to build intelligent decision support systems for predicting crude oil prices. The proposed model was able

Kertas kerja ini bertujuan untuk membincangkan penggunaan bahasa oleh guru dalam pengajaran dan pembelajaran (PdP) kemahiran berfikir. Ia akan mendefinisikan konsep bahasa kognisi dalam PdP guru. Seterusnya, menjelaskan dan membincangkan aspek-aspek bahasa tersebut. Ketepatan menggunakan bahasa dalam menjana keupayaan berfikir akan memberi kesan ke

Cognitive Radio (CR) technology has been introduced to solve the problems of spectrum underutilization and spectrum scarcity caused by improper spectrum management policies. The main concept of Cognitive Radio Ad Hoc Network (CRAHN) is that, in a wireless ad hoc network, the unlicensed users (or Secondary Users (SUs)) are allowed to access the temp

Natural products are a promising area for researchers from various fields since there are many benefits exhibit from the application of the natural product especially in food application and medicinal purposes. Bioactive compounds, the natural products that mostly found in fruits and vegetables, has shown an increasing demand as one of the importan

Parallel to the achievement of the Takaful industry, agency system becomes the main medium utilised by the industry to educate the public and assist them about future financial preparation. As a mirror to an Islamic type of insurance, Takaful agents play significant role not limited to sell the Takaful products, but to behave base on the Islamic no

Introduction: Malaysia has experienced a significant expansion of dental schools over the past decade. Research into students’ motivation may inform recruitment and retention of the future dental workforce. The objectives of this study were to explore students’ motivation to study dentistry and whether that motivation varied by students’ and

This paper presents a conventional DC-DC boost converter for low and wide voltage supply range, suitable for energy harvesting purpose. The output voltage can be increased by controlling the transistor switching frequency, duty cycle,inductance, load capacitor, rise, and fall time. Both computer simulation and experiment results are performed in de

This paper presents a parametric sweep analysis discussion on proposed DC-DC boost converter circuit for low and wide voltage supply range. Analysis is initially done using computer simulation and then tested with experimental work. Results are combined and discussed in details. In this work, effect of parameter such as input voltage, switching fre
