The performance study on wavelet based OFDM and Fourier based OFDM with the focus on impulse noise effects is demonstrated. The models of the inverse and forward transforms are also constructed to show the OFDM system process. The BER performances in three scenarios when varying the Poisson recurrence parameter a from small to large are obtained. I

A performance study on wavelet-based OFDM, particularly using DWT OFDM as substitutions for Fourier-based OFDM with the focus on impulse noise effects is demonstrated. The models of the inverse and forward transforms are discussed. The details about each model and study the BER performance in two scenarios when varying the Poisson recurrence parame

Background: Auditory brainstem response (ABR) can be influenced by cognitive task due to the sensory inhibition process known as auditory sensory gating. The ABR wave V amplitude has been reported to decrease with cognitive tasks compared to the standard ABR. Any abnormality in the ABR cognitive task may suggest a possibility of auditory sensory ga

The truck chassis is a major component in a vehicle system. In the design process of the vehicle, the chassis frame is often subjected to refiiement in order to develop vehicles with reduced cost and weight [I]. The application of FEA is used to reduce component complexity, weight and subsequently cost.ADVANCED TOPICS IN MECHANICAL BEHAVIOR OF MATE

In common practice of education, we create learning objectives and assessment questions based on Bloom taxonomy of behavioral objectives. Bloom taxonomy has assisted teachers in transforming learning from low to high order thinking. Unfortunately, Bloom taxonomy has encountered a shortcoming of the assumption of men as merely the body and mind with

This paper discusses a study to find out whether philosophical inquiry (PI) can be used as a tool to develop critical thinking among the undergraduate students of the Faculty of Islamic Revealed Knowledge and Human Sciences (IRKHS), International Islamic University, Malaysia (IIUM). This qualitative study, involved two groups of students students w

In Islam, marriage contract is a sacred link that brings man and woman together. It gives the marital relation its legal cover. So, for this relation to be stable and fulfill its objectives, it should be established based on clarity and mutual consent between the two parties. Thus, if a party suffers a physical or mental defect of which the other p

Quality management is an important aspect in all kinds of businesses – manufacturing or service. Idea generation plays a pivotal role in managing quality in organizations. It is the new and innovative ideas which can help orporations to survive in the turbulent business environment. Research in group dynamics has shown that more ideas are generat

There are many ways of analysing effectiveness of learning especially in computer learning environment. However, not much attention has been given to analyse it from fuzzy theory perspective. Due to the fuzziness in perception toward learning, this paper presents an application of fuzzy set conjoint model in analyzing students’ perceptions on lea

Simulation approaches using MATLAB for wavelet based OFDM, particularly in DWT-OFDM as alternative substitutions for Fourier based OFDM are demonstrated. Conventional OFDM systems use IFFT and FFT algorithms at the transmitter and receiver respectively to multiplex the signals and transmit them simultaneously over a number of subcarriers. The syste
