Effects of MEMS Material on Designing a multi-Band Reconfigurable Antenna
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract—In this work, two adjacent patches and MEMS switches are proposed a reconfigurable antenna that is capable of operating at several frequencies. Optimization of wing patches is done to obtain more than three resonant frequencies of the antenna by selecting the MEMS cantilever bridge materials. The study shows that the material of MEMS swi

A fuzzy-Based Mobility Prediction in the Ieee 802.16e
Research Output | Dar Al-hikmah Library | IIUM Only

Intersystem mobility having no awkward transitions or indications of disparity, roaming across wireless access networks is one of the main features of Mobile WiMAX. In this paper, we propose a mobility prediction method based on fuzzy logic control and an algorithm similar to the fuzzy c- mean partitioning to predict the movement patterns and hando

Prospect for Nuclear Engineering Education in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

The use of nuclear power for electricity generation using nuclear power reactors are well-known. Malaysia is considering the use of nuclear power in her energy mix. Engineers with nuclear engineering background will be needed alongside other engineering disciplines. The planning window for a national nuclear power program is long, but the need to g

Adsorption of Chromium from Water by Carbon Nanotubes Grown on Powdered Activated Carbon
Research Output | Dar Al-hikmah Library | IIUM Only

Lab-scale experiments were conducted and the adsorption of chromium (Cr) from aqueous solution by using carbon nanotubes (CNTs) grown on powdered activated carbon (PAC). The product is named PACNT. The effects of pH, PACNTs dosage, contact time and initial Cr concentration were studied at ambient room temperature (±25° C) and with a constant agit

Hydrodynamic Effects During Waste Cooking Oil Transesterification Using Cfd
Research Output | Dar Al-hikmah Library | IIUM Only

This work is presented as part of a preliminary study to model transesterification of Waste Cooking Oil (WCO). A Computational Fluid dynamics (CFD) technique was used to simulate flow of WCO in a 2 Litre reactor. A turbulent model of the Naviers Stokes' equation was used to solve the transient form of the equation for an axisymmetrical 2-D mode

Effect of Process Parameters on Abrasive Contamination During Water Abrasive Jet Machining of Mild Steel
Research Output | Dar Al-hikmah Library | IIUM Only

In the area of grit blasting, it is well known that microscopically small abrasive debris gets trapped on the surface, and due to impact the grits might cause the surface to fracture and a fraction of it to be embedded. The same problem appears in abrasive water jet (AWJ) machining especially in the so-called deformation wear zone or striation zone

Optimisation of Arsenic Adsorption from Water by Carbon Nanofibres Grown on Powdered Activated Carbon Impregnated with Nickel
Research Output | Dar Al-hikmah Library | IIUM Only

Contamination of water due to arsenic (As) is increasing in many parts of the world. The removal of As from aqueous solution by using impregnated Carbon Nanofibres (CNFs) as the adsorbent is reported in this paper. The effects of pH, CNFs dosage, contact time and initial concentration of arsenic were studied at room temperature (± 25° C). The int

The Role of socio-Economic Factors on Household Waste Generation: a Study Hi a Waste Management Program in Dhaka City, Bangladesh
Research Output | Dar Al-hikmah Library | IIUM Only

Information on waste generation, socio economic characteristics and willingness of the households towards waste separation of waste were obtained from interviews with 402 respondents in Dhaka city. Ordinary Least Square (OLS) regression was used to determine the dominant factors that might influence the waste generation of the households. The resul
