Electrical Behaviour of yttrium-Doped Potassium Sodium Niobate Thin Film for Piezoelectric Energy Harvester Applications
Research Output | Dar Al-hikmah Library | IIUM Only

This study evaluates how the electrical characteristics of potassium sodium niobate, K0.5Na0.5NbO3 (KNN) thin film, are affected by yttrium doping. For the KNN thin films doped with yttrium, the secondary phase was not observed, which means that the films preserved the orthorhombic lattice. Yttrium doping affected the grain structure where microsco

Squalene Recovery from Palm Fatty Acid Distillate Using Supercritical Fluid Extraction
Research Output | Dar Al-hikmah Library | IIUM Only

The objective of this research is recovery of squalene from palm fatty acid distillate (PFAD) using supercritical fluid extraction (SFE). The extraction process was performed by using the SFE and recovered squalene was analyzed from total lipid extracts using HPLC. A central composite design was used to study the effect of SFE variables namely pres

Research Output | Dar Al-hikmah Library | IIUM Only

Previous studies have demonstrated that the seaweed, Gracilaria manilaensis, has a high potential of producing agar for the food industry, and is a promising candidate as a dietary supplement for treating cancer and neurological disorders. Unfortunately, not many farms culturing G. manilaensis existed particularly in Malaysia. One of the reasons is

Application of Permanent Magnets for Chatter Control in End Milling of Titanium Alloy Ti-6al-4v
Research Output | Dar Al-hikmah Library | IIUM Only

Machining of metals is generally accompanied by a violent relative vibration between work and tool, known as chatter. Chatter is undesirable due to its adverse effects on product quality, operation cost, machining accuracy, tool life, and productivity. This paper presents an innovative approach to chatter control during end milling of titanium allo

Study the Growth of Microalgae in Palm Oil Mill Effluent Waste Water
Research Output | Dar Al-hikmah Library | IIUM Only

This paper emphasizes mainly on the biomass productivity and lipid content of two microalgae strains known by their high lipid content namely: Botryoccocus sudeticus and Chlorella vulgaris. These starins were first screened for the highest biomass and lipid content, then Plackett-Burman design was used to evaluate the significant media for grown wh

Assessing the Effect of Mergers and Acquisitions on Revenue Efficiency: Evidence from Malaysian Banking Sector
Research Output | Dar Al-hikmah Library | IIUM Only

The article attempts to examine the effect of mergers and acquisitions (M&As) on Malaysian banks’ revenue efficiency. The data gathered in this study are divided into two event windows: the pre-merger (1995–1996) and post-merger (2002–2009) periods. The sample selected for this study comprised 34 commercial banks, including the control gr

Information and Communication Technology Workforce Employability in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose – The purposes of the study are to understand ICT workforce employability in Malaysia, to identify the causes that influence the growth of skill gaps in the ICT workforce, and to determine ways to reduce these gaps. Design/methodology/approach – The methodology of the study comprised project reports and a literature review. Findings –

Exploring Death Anxiety and Mental Health Among Adults Living in Lembah Klang, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

The study of death anxiety in psychology is increasing however, it is still at its infancy. Thus, this study aims to explore mental health (depression, anxiety and stress) and death anxiety among adults living in Lembah Klang, Malaysia. A number of 309 respondents volunteered to participate in this study and completed the questionnaires. The questi

A Real Time Deep Learning Based Driver Monitoring System
Research Output | Dar Al-hikmah Library | IIUM Only

Road traffic accidents almost kill 1.35 million people around the world. Most of these accidents take place in low and middle-income countries and costs them around 3% of their gross domestic product. Around 20% of the traffic accidents are attributed to distracted drowsy drivers. Many detection systems have been designed to alert the drivers to re

On the Evaluation of Negative Altitude Requirement for Flutter Speed Boundary of Transport Aircraft and Uav
Research Output | Dar Al-hikmah Library | IIUM Only

To maintain flight safety, all transport aircraft designs should satisfy airworthiness standard regulation. One fundamental issue of the aircraft design that relates directly to flight safety as well as commercial aspect of the aircraft is on the evaluation of the maximum speed within the designated flight envelope. In the present work, a study is
