Simulations of Surface and Bulk Acoustic Wave MEMS Biosensors
Research Output | Dar Al-hikmah Library | IIUM Only

Traditionally a telecommunication device, the emerging application of acoustic wave devices as sensors is rapidly gaining attention due to its high sensitivities. In this work, a comparative study of surface (SAW) and bulk (BAW) acoustic wave biosensors is presented. The MEMS SAW resonator is formed using a lithium niobate substrate with Al electro

Simulation of a Surface Transverse Wave Biosensor for Df-1 Cells
Research Output | Dar Al-hikmah Library | IIUM Only

A 250MHz Surface-Transverse Wave (STW) resonator is employed as a sensor element for the detection of DF-1 cells. STWs are horizontally polarized shear waves which are generated and detected by the interdigitated transducers (IDTs) similar to surface-acoustic wave (SAW) resonators. Detection of chemical and biological agents in aqueous solutions is

A New Method for the Analysis of Combined Operation of electro-Osmotic Dewatering and Mechanical Expression
Research Output | Dar Al-hikmah Library | IIUM Only

Electro-osmosis is especially effective in removing liquid from sludge of colloidal particles for which conventional mechanical dewatering is not very successful. This work presents results of experimental work carried out to study and analyze the combined operation of electro-osmotic dewatering (EOD) and mechanical expression (ME) by use of the Te

Fatty Acid, Mineral and Heavy Metal Contents of Different Malaysia Fish Species
Research Output | Dar Al-hikmah Library | IIUM Only

Fish are popularly recognized as an excellent source of lipids that are composed of a wide range of important fatty acids. Fish also contain good quality protein and are an adequate source of many vitamins (e.g. fat soluble A, D, E and the water soluble B-complex), in addition to important minerals such as calcium and phosphorous. We recently inves

Efficient Method for the Purification of Coagulated Sewage Secondary Effluent
Research Output | Dar Al-hikmah Library | IIUM Only

Constant rate microfiltration experiments are conducted in purification of sewage secondary effluent pretreated with polyaluminum chloride (PAC). Monolithic ceramic membrane having a nominal pore size of 1.0 micro meter with 19 tubular channels is used as a filter medium. The system is capable of selecting the required mode of membrane cleaning, i.

Acoustic Perception Features in Normal Hearing Adults and Children (Ciri-ciri Persepsi Akoustik di Kalangan Dewasa dan Kanak-kanak Yang Berpendengaran Normal)
Research Output | Dar Al-hikmah Library | IIUM Only

Psychophysical studies are elemental ways to describe sound perception which includes the identification of perceptual differences in children, young and older adults. This study summarizes various psychophysical abilities with aims to provide better understanding in the perceptual development of normal hearing subjects. This study investigated fre

step-Stress Model Using Logistic Regression Model and its Application in Medicine
Research Output | Dar Al-hikmah Library | IIUM Only

A linear logistic model is proposed for estimating the probability of survival to a specified stage using a step-stress model. Parameter estimates may be obtained numerically for the general case of the k-step model, and explicit solutions are given in the case of the two-step stress model. Of special interest to us is the application of this model

Prosedur Perkahwinan Melalui Wali Raja: Isu dan Penyelesaian
Research Output | Dar Al-hikmah Library | IIUM Only

Perkahwinan adalah merupakan satu ikatan yang suci yang dituntut oleh agama. Oleh itu, untuk memasuki perkahwinan, terdapat rukun-rukan dan syarat yang perlu dipatuhi. Salah satunya ialah persetujuan daripada wali pihak perempuan. Sekiranya persetujuan wali tidak diperolehi atau tiada wali, perempuan tersebut boleh memohon untuk melangsungkan perka

Towards a Long Term Development Vision for Bangladesh: Some Socioeconomic and Legal Aspects
Research Output | Dar Al-hikmah Library | IIUM Only

Following modernization paradigm and some local dynamics conducive to development, some Asian countries emerged as economic tigers in the world. Conversely, other Asian countries including Bangladesh failed to taste economic development despite having monetary and technological aids from some developed nations. Drawing on some social and historical

Privacy and Technology: Implications and Challenges
Research Output | Dar Al-hikmah Library | IIUM Only

The meaning of Privacy has been changed since the massive invasion of Information and Communication Technology (ICT) into our private life.The advances in technology have greatly expanded our ability to acquire private and confidential information. Increasingly, technology is being developed to expand our capacities to monitor ongoing actions. Maki
