Free Space Optics (FSO) communication is a technology widely used today. It involves transmission of data from a transmitter to a receiver. In order to achieve successful data transmission, a continuous alignment between the transmitter and receiver telescope is needed. If not, misalignment will happen due to certain factors. Vibration at the trans

This paper shows the simulation results of the effects of phase difference on the output ripple voltage of a low voltage power supply circuit. The circuit uses a rectifier circuit which adds the squares of two out-of-phase sine waves. The circuit focuses on the constraint of rectifying a low voltage input AC source while analyzing the ripple voltag

This paper discusses obtaining further results looking at the implementation of a full-wave rectifier based on phase-modulation. Phase modulation is used to obtain a low-voltage DC supply by controlling phase-angle through changes in a variable resistor and capacitor. This property allows for AC rectification along with an inherent voltage regulati

The Mechatronics engineering program at the faculty of engineering, International Islamic University Malaysia (IIUM) was established in 1994. It came into existence as a full-fledged department in 1998. Ever since its establishment, the department has produced the largest number of engineering students from IIUM and has been renowned as one of the

Stroke ranks top five causes of mortality in Malaysia with the rate of 8.3/100,000 population. Stroke are characterised by acute neurological deficits and mostly associated with vascular causes. Risk factors which contribute towards 90% of overall stroke are hypertension, unhealthy diet, physical inactivity, excessive alcohol intake, psychosocial s

Malaysia is moving towards improving its land administration delivery system by implementing electronic conveyancing. This is evident through the submission of a proposal paper forwarded by the Department of Director of Land and Mines, Ministry of Natural Resources and Environment. One of the proposals is concerning the implementation one title sys

The strata titles law in Peninsular Malaysia has been first embodied in its own statute namely the Strata Titles Act, 1965. Prior to the enforcement of this main statute, the law on sub-divided buildings stood as part of the types of titles in the National Land Code, 1965 which was known as “subsidiary title”. The Strata Titles Act, 1965 may be

Muslim consumers are beginning to be more concerned whether the current e-commerce processes are mixed with un-Islamic elements such as, riba (interest), gharar (uncertainty), and Maisir (gambling). To clarify the misconception, it is suggested that an assurance be given by a reputable Islamic religious authority to the effect that Internet seller

Purpose: Dry eye symptoms are commonly reported par- ticularly in women post-menopause. This study explored the relationship between levels of plasma sex hormones and dry eye symptoms. Method: A cross-sectional, single visit study was conducted. The study involved a convenience sample of 74 subjects without ocular surface disease, including 52 fema

This book presents the development of mechanical powered portable charger to charge mobile phone during disaster recovery. It emphasizes on efficient mechanical energy harvesting circuit for charging mobile phone battery with the utilization of intermediate battery. In this book, Sealed Lead-Acid (SLA) or dry battery was selected as an intermediate
