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

Rukhsoh (permit) is a concessionary law, which oppose to azimah (enforced) in Islamic jurisprudence. It is considered as one of the important concept to be understood by Muslims physicians and scientists as its applications offer solutions for hardships and difficulties in performing practical acts of worship. However, discussions regarding this ma

Urinary bladder diverticulum tumour is rare. It has been estimated that only 2.6% of all bladder diverticulum develop malignancy and most were diagnosed late. Delay in diagnosis can be due to presence of intra-diverticular stone which can compress and hide any evidence of mucosal changes. We report the case of a 53-year-old man who presented with m

This paper presents the outcome of the experimental investigation conducted to control the base pressure for suddenly expanded flow for a fairly high area ratio of non-dimensional backward facing step height of 2.2. The Mach number range of the study were from 1.25 to 3.0 and the NPRs in the range from 3 to 11. The length-to-diameter ratio of the p

Malaysia has experienced a rapid expansion in the number of dental schools. Five factors have influenced their choice of professional career, with ‘academic’ factor being the most important. Research into the career expectations of emerging graduates is important to inform career planning and workforce retention. The objective of this study was

Over the last decade Islamic banking has clear taken root. What began as novelty has made major strides. The main purpose of this paper was to explain the applicability of ‘urf in Islamic deposit products. This study set about the application of ‘urf in Islamic law briefly, moreover, the concept of deposit products in conventional bank just ana

The main purpose of vehicle suspension system is to isolate the vehicle main body from any road geometrical irregularity in order to improve the passengers ride comfort and to maintain good handling stability. The present work aim at designing a control system for an active suspension system which is widely applied in today’s automotive industrie

This paper can be considered as a research on Algebraic Differential Geometry. It is about differential rational invariants of subgroups of the Affine group over the constant fields of partial differential fields (characteristic zero). The obtained results can be formulated in terms of Differential Geometry as follows: 1. For any motion group repre

A pure algebraic approach to differential invariants of curves and surfaces is presented. By the use of this approach the explicit formulae for the generating differential invariants and invariant differential operators for the generic curves in n-dimensional classical geometries are considered.2nd Reading October 8, 2014 14:47 WSPC/S0219-4988 171-
