A Planar Wideband Inductively Coupled Feed Patch Antenna for Uhf RFID Tag
Research Output | Dar Al-hikmah Library | IIUM Only

A planar wideband patch antenna for ultra�high frequency (UHF) radio frequency identification (RFI D) tag for metallic applications is presented in this research work. Three different shape patches are inductively coupled to a triangle loop to excite three resonances close to each other to f orm wide impedance bandwidth for universal application

A Planar Wideband Microstrip Patch Antenna for Uhf RFID Tag
Research Output | Dar Al-hikmah Library | IIUM Only

In this research, a planar wideband microstrip patch antenna for passive radio frequency identification (RFID) tag is proposed. To enable universal operation by covering the operating frequency of ultra-high frequency (UHF) RFID band from 860 MHz to 960 MHz, two C-shaped patches are employed. Both of the patches are inductively coupled fed by a rec

Comparative Study on Quality Awards
Research Output | Dar Al-hikmah Library | IIUM Only

Background: quality awards are known as one of the research interests in quality management sector. Objective: This study tries to compare quality awards. Results: In the first part we focused on Malaysian quality award, aim to introduce it as one of the successful quality awards systems. Then in the next phase of the paper we try to review the joi

An Iteration Problem
Research Output | Dar Al-hikmah Library | IIUM Only

Let F stand for the feld of real or complex numbers, \phi : F^n\rightarrow F^n be any given polynomial map of the form \phi(x) = x + "higher order terms". We attach to it the following operator D : F[x]\rightarrow F[x] defined by D(f) = f-f\circle\phi, where F[x] = F[x_1; x_2; ...; x_n]- the F-algebra of polynomials in variables x_1; x_2;..

Paint Palette Used by Iranian Masters Based on Persian Medieval Recipes
Research Output | Dar Al-hikmah Library | IIUM Only

Classical Iranian literary sources contain valuable information with respect to materials and techniques related to the art of book-making, including pigments and dyes. Some of these writings have been composed in the form of mystical poetry which needs professional research into the language and classical terms used. Studying these primary sources

Maqasid, Social Responsibility and Islamic Investment
Research Output | Dar Al-hikmah Library | IIUM Only

In view of recent debates and trends in Islamic finance, this paper seeks to reflect the practice of Islamic investment in the light of the Maqasid as-Shari’ah (objectives of the Shari’ah). Specifically, it attempts to argue for the incorporation of broader social responsibility concerns in the screening criteria of Islamic investment practices

Conceptualizing a Strategic Framework of Social Responsibility in Islamic Economics
Research Output | Dar Al-hikmah Library | IIUM Only

In developing Islamic economics as a discipline, its proponents have emphasized on religious and ethical postulations of its economic agents as the essential micro-foundation towards the realization of its normative goals. Nevertheless, recent debates have highlighted the growing frustration on the failure of Islamic finance in addressing ethical a

Kinetic Studies on Recombinant Stem Bromelain
Research Output | Dar Al-hikmah Library | IIUM Only

Stem bromelain is a plant thiol protease with several industrial and therapeutic applications. This current work presents kinetic studies of recombinant bromelain (recBM) expressed in Escherichia coli BL21-AI on foursynthetic substrates, N-α-carbobenzoxy-L-alanyl-p-nitrophenylester (ZANPE), N-α-carbobenzoxy-L-arginyl-L-ar-ginine-p-nitroanilide (Z

Wall Thinning and Creep Damage Analysis in Boiler Tube and Optimization of Operating Conditions
Research Output | Dar Al-hikmah Library | IIUM Only

The boiler tubes are operated continuously at high temperature and pressure. During operation,scales are formed in boiler tube due to tube geometries, flue gas and steam temperature. The remaining wall thickness decreases due to the formation of scale which eventually causes failure of the boiler tubes. In this investigation an iterative technique

Performance Evaluation of Pv Module Using Water Filters and Infrared Reflective Glass Covers
Research Output | Dar Al-hikmah Library | IIUM Only

The Photovoltaic (PV) system converts only a selected band (0.35μm to 0.82 μm) of solar radiation to electricity. The absorption of radiation outside this band leads to a temperature raise of PV module which affects its performance. Experiments were performed to prevent radiation outside the selected to reach the PV panel using water filtersand d
