A Study on Problems, Roles and Factors Affecting Perceived Effectiveness of Course Leader Performance
Research Output | Dar Al-hikmah Library | IIUM Only

The present study examined problems faced by course leaders at three different stages (planning, during semester and post semester), their perceptions on their course leader roles and investigated their perceived role effectiveness in leading and managing courses as part and parcel of their role as lecturers. Fifty nine course leaders were involved

Optimization of Process Conditions for Lactic Acid Recovery Using Organic Base
Research Output | Dar Al-hikmah Library | IIUM Only

Lactic acid has a wide range of applications in food, pharmaceutical and cosmetics industries. The global market for lactic acid in foods is estimated at 275,000 tons with average annual growth of 10 per cent. The persistent demand of pure and naturally produced lactic acid in food and beverage applications attracted researcher’s interest towards

Employee Motivation: a Malaysian Perspective
Research Output | Dar Al-hikmah Library | IIUM Only

It is a challenging task for managers to keep employees motivated in their works in order to achieve the organizational goals. Due to the varied nature of human beings, a factor that can motivate someone, may not do so in others. Therefore, it is important for managers to know the ‘exact’ motivators for his/her employees. The present research i

Aerodynamic Models for darrieus-Type straight-Bladed Vertical Axis Wind Turbines
Research Output | Dar Al-hikmah Library | IIUM Only

Since ancient past humans have attempted to harness the wind energy through diversified means and vertical axis wind turbines (VAWTs) were one of the major equipment to achieve that. In this modern time, there is resurgence of interests regarding VAWTs as numerous universities and research institutions have carried out extensive research activities

Analysis of Control Policies and Dynamic Response of a q-Car 2-dof Semi Active System
Research Output | Dar Al-hikmah Library | IIUM Only

Several control policies of Q-car 2-DOF semiactive system, namely skyhook, groundhook and hybrid controls are presented. Their ride comfort, suspension displacement and road-holding performances are analyzed and compared with passive system. The analysis covers both transient and steady state responses in time domain and transmissibility response i

A New Airfoil for the Supporting Struts of smaller-Capacity straight-Bladed Vawt
Research Output | Dar Al-hikmah Library | IIUM Only

The primary sources of drag for a straight-bladed vertical axis wind turbine (SB-VAWT) are the blades which are also responsible for generating lift. The supporting struts of a SB-VAWT are also responsible for generating additional parasitic drag which reduces the overall power output. It is one of the major disadvantages of the SB-VAWTs as the los

An Assessment of semi-Active Suspension for Passenger Cars Using full-Car Model
Research Output | Dar Al-hikmah Library | IIUM Only

Several control policies of F-car 7-DOF semiactive system, namely skyhook, groundhook and hybrid controls are presented, as a continuation of the previous work on Q-car 2-DOF and H-car 4-DOF models. Their ride comfort, suspension displacement and road-holding performances are analyzed and compared with passive system. The analysis covers both trans

Device Characteristics of Carbon Nanotube Transistor Fabricated by Direct Growth Method
Research Output | Dar Al-hikmah Library | IIUM Only

We have fabricated carbon nanotube �CNT� ﬁeld-effect transistors �FETs� by direct growth of single-wall CNTs between the source and drain electrodes, and investigated their device characteristics. The FETs show ambipolar operation. The temperature and bias voltage dependence of device characteristics are consistent with device operation o

Integration of Environmental Performance in a Virtual Reality Framework: Case Study of Putrajaya
Research Output | Dar Al-hikmah Library | IIUM Only

Microclimate studies are commonly required for new projects especially urban masterplanning that involves the development of a sizeable area within a city. Basically data from microclimate studies gathered from semioutdoor spaces i.e. on airflow, sunlight, lighting and irradiation are typically gathered through field measurements and environment si
