the microstructural features of the weld section which are controlled by the energy input and heat transfer factors. The welding current, travel speed and the material property govern these parameters. However, the specific influence of range of heat input rates on the microstructural features of FSS weld is hardly reported. This paper reports the

Regional maps and equations for the magnitude and frequency of 1, 7 and 30-day low flows were derived and are presented in this paper. The river gauging stations of neighbouring catchments that produced similar low flow frequency curves were grouped together. As such, the Peninsular Malaysia was divided into seven low flow regions. Regional equatio

An efficient, effective and sustainable water services are very crucial for human survival. The Malaysian government has recently restructured its legal and institutional framework of water supply services after realizing that the existing regulatory structure did not work effectively for the water industry. The restructuring process has necessaril

A Capacitive Micro-machined Ultrasonic Transducer (cMUT) is presented. It is a new type of transducer that can be used to transmit and receive ultrasonic signals in medical scanners and a variety of other applications. The behavior of cMUT is investigated based on a proposed model of an equivalent circuit by which the characteristics are predicted.

Carbon nanotubes (CNTs) are interesting materials which are being researched intensively in the past few year. Application of CNTs in water treatment with their unique properties has attracted the attention of many scientists and engineers. Moreover, manipulation of CNTs with other polymers has been done for different applications. This study descr

Purpose – The main purpose of this paper is to investigate the acceptance level of Islamic accounting course by undergraduate students at the Universiti Malaysia Sabah (UMS). The study used theory of reasoned action (TRA) to analyze the findings. Design/methodology/approach – The primary data for the study are collected using self-administered

The design of a prototype monolithic Micro Electro-Mechanical Systems (MEMS) electronic circuits, namely the Voltage Controlled Oscillators (VCOs) is presented. The components can achieve the stringent requirements of wireless communication applications such as GSM cellular telephony. The VCO meets the low phase noise specifications of -136 dBc/Hz

Modeling and design of a single photon detector and its various characteristics are presented. It is a type of avalanche photo diode (APD) designed to suit the requirements of a Quantum Key Distribution (QKD) detection system. The device is modeled to operate in a gated mode at liquid nitrogen temperature for minimum noise and maximum gain. Differe

The Performance of Orthogonal Frequency Division Multiplexing (OFDM) combined with Quadrature Amplitude Modulation (QAM) has been analyzed in presence of fiber optic dispersion. The influence of dispersion on the (OFDM) spectrum is investigated with fiber lengths, bit rates, no. of channels and source line widths. The inter-channel interference occ

Many configurations of EDFA producing triple pass EDFAs have been used, however, only two configurations are commonly used in the optical fiber communication system due to their high performance. Those two configurations are configured in a double stage EDFA. The first configuration is (configuration A) consists of a single-pass EDFA as the first s
