Effect of Modulation Index of Pulse Width Modulation Inverter on Total Harmonic Distortion for Sinusoidal New
Research Output | Dar Al-hikmah Library | IIUM Only

Knowing Total Harmonic Distortion (THD) content of voltage source inverter (VSI) is important and must be within the allowable range. Several schemes are suggested to mitigate THD and to produce as much a sinusoidal output signal as would be possible. One of such schemes is using a Sinusoidal Pulse Width Modulation SPWM-based inverter. SPWM is usua

Modulation Optimization Effect on Total Harmonic Distortion of Single Phase h-Bridge Inverter Based Selective Harmonics E Limination Technique New
Research Output | Dar Al-hikmah Library | IIUM Only

Specific odd harmonics can be mitigated by operating the simeconductor switches in H-bridge inverters at optimized switching angles of the PWM signals. These switching angles can be achieved by calculating a set of nonlinear equations using Selective Harmonic Elimination Pulse Width Modulation (SHE PWM) technique. Modulation index (m) is a signific

The Role of Training for Dental Students in Scoring Caries New
Research Output | Dar Al-hikmah Library | IIUM Only

INTRODUCTION: Training is essential in order to get a similar result in scoring caries. International Caries Detection and Assessment System (ICDAS) is used in this training. The objectives of this study is to examine dental students 3 months consistency in scoring caries after baseline training, calibration and retraining at 3 months time compare

Identification of an Unknown Bacteria and Evaluation of its Potential Use in Bioremediation New
Research Output | Dar Al-hikmah Library | IIUM Only

Enzymes are macromolecular biological catalysis that is important to speed up reaction. Enzymes can be found naturally from the microorganism such as bacteria, fungi and yeast which may not be genetically modified. In this perspectives, resorting to bioremediation to clean-up such environment may prove feasible and beneficial as microorganisms effe

Immigrant Entrepreneurs in Malaysia: an Exploratory Study on their Business Success and Prospects in Small Retail Business New
Research Output | Dar Al-hikmah Library | IIUM Only

International migration is increasingly prevalent in the global economy. Research has, amongst others, included their social experiences, cultural and psychological perspectives. Little is however known about their involvement in small businesses in receiving countries. The literature tends to suggest that decisions of immigrant entrepreneurs’ in

A Practical and Interactive web-Based Software for Online Qur'anic Arabic Learning New
Research Output | Dar Al-hikmah Library | IIUM Only

The intent of this paper is to summarize and analyze the data and experience earned from a practical implementation of online language learning approach specifically targeted to Qur’anic Arabic learning. The foundation of this work is based on the fact that in the current world, almost 80% of the Muslims are non-native speakers/users of Arabic la

Dynamics of Doubly Stochastic Quadratic Operators on a finite-Dimensional Simplex New
Research Output | Dar Al-hikmah Library | IIUM Only

The present paper focuses on the dynamics of doubly stochastic quadratic operators (d.s.q.o) on a finite- dimensional simplex. We prove that if a d.s.q.o. has no periodic points then the trajectory of any initial point inside the simplex is convergent. We show that if d.s.q.o. is not a permutation then it has no periodic points on the interior of t

Dynamics Classifications of Extreme Doubly Stochastic Quadratic Operators on 2d Simplex New
Research Output | Dar Al-hikmah Library | IIUM Only

We study the dynamics of extreme doubly stochastic quadratic operators (d.s.q.o.) on two dimensional (2D) simplex. We provide some examples of d.s.q.o. which have infinitely many fixed points. We prove that the trajectory of extreme d.s.q.o., starting at some interior point of the simplex is convergent. Finally, we classify the dynamics of all extr

Towards Devising a Fundamental Theory of Islamic Advertising New
Research Output | Dar Al-hikmah Library | IIUM Only

Advertising plays a significant role on socio-economic fronts. It not only lubricates the economic traffic, but also raises the standard of living by offering newer and better products. But at the same time advertising is not without criticism. Critics say advertising is the cause of many socio-economic evils. Polluting the moral and cultural value
