The Effect of Particle Size Distributions on Dust Storm Attenuation Prediction for Microwave Propagation
Research Output | Dar Al-hikmah Library | IIUM Only

Dust storm effect on microwave signal attenuation has attracted many researchers recently. Many prediction models have been developed in order to predict microwave signal attenuation during the dust storm. Most of the dust storm prediction models have ignored the variation of the particle size inside the dust storms. Therefore, their predicted resu

Heavy Metal Contents in Highway Runoff in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Pavement runoff is considered as one of the major non-point pollution sources of heavy metals from typical urban areas. Storm runoff from five highway toll plazas located within the Klang Valley is being collected to study the heavy metal content. This study reports the initial findings on the common metallic pollutants, namely Lead (Pb), Zinc (Zn)

Teachers’ Attitudes Towards code-Switching in the English as a Foreign Language Classroom
Research Output | Dar Al-hikmah Library | IIUM Only

Code-switching has always been an intriguing phenomena to sociolinguists. While the general attitude to it seems negative, people seem to code-switch quite frequently. Teachers of English as a foreign language too frequently claim that they do not like to code-switch in the language classroom for various reasons – many are of the opinion that onl

Construction and Demolition Wastes and its Management: a Case Study in Klang Valley, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Many activities in construction and demolition projects are generally considered as complicated and unfriendly that may affect surrounding environment and public health. Construction, remodeling, repairing or demotion works of buildings and roads generate large amounts of hazardous and nonhazardous materials. This study highlights the major types o

Influence of Differential Spoiler Settings on the Wake the Vortex Characterization and Alleviation
Research Output | Dar Al-hikmah Library | IIUM Only

Experimental investigations using particle image velocimetry technique have been carried out for the evaluation of the differential spoiler setting capabilities in modifying the spanwise wing load and further reduce the wake vortex hazard. The aircraft half model (at high lift configuration) was investigated for two differential spoiler settings. R

Wireless decode-And-forward Relay Channels: Time Allocation Strategies for Cooperation and Optimum Operation
Research Output | Dar Al-hikmah Library | IIUM Only

Relay channels have been in use for decades as an effective means to tackle some of the challenges facing wireless transmission. Recent studies considered re-employing the relay channel to serve modern wireless systems. Material offered in this book was originally presented by the author as a thesis for the degree of Ph.D. to University College Lon

Dawah as the Prophetic Mission
Research Output | Dar Al-hikmah Library | IIUM Only

Dawah is an invitation to someone to participate in some event or to do something. Islamic Dawah is the call to the Truth, to the way of God, the straight path, as well as to the virtuous, dignified and contended life. It invites humanity to comprehend and invoke the ‘Absolute Reality’, a living force behind all realities that derive their stre

Quantum Properties of the three-Mode Squeezed Operator: Triply Concurrent Parametric Amplifiers
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we study the quantum properties of the three-mode squeezed operator. This operator is constructed from the optical parametric oscillator based on the three concurrent χ(2) nonlinearities. We give a complete treatment for this operator including the symmetric and asymmetric nonlinearity cases. The action of the operator on the number

Crime and the Planning of Residential Areas- a Comparative Analysis of Two Taman Melati Terrace Housing Units
Research Output | Dar Al-hikmah Library | IIUM Only

Globally, the design of the built environment has played a crucial role in preventing design. Increasingly, two school of thoughts namely Defensible Space and New Urbanism are seen as guiding the CPTED agenda for the coming decades. This paper aims to explore the relationship between residential crime and the design of the built environment in rela
