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

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

The term fair price is commonly used in retail business. To encourage retail business outlets to keep fair prices for their products, Malaysian Government has instituted Fair Price Shop Awards since 2003. More than 100 retail outlets win this award every year in 14 categories. The present paper attempts to identify the most common strategies that h

The paper discusses the processes of implementing virtual reality to highlight salient aspects of traditional urban planning and constructional aspects of a heritage complex; and the development of three dimensional (3D) user interfaces to view and navigate through the model.The interface allows flexible navigation to explore the space and construc

Modern wind turbines are categorized as horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs), which are currently being utilized for diversified applications. The basic theoretical advantages of VAWTs are: (i) they accept the wind from any direction, and (ii) the generator, gearbox etc. can be placed on the ground. Selectio

In this paper, a 1 kW straight-bladed vertical-axis Darrieus wind turbine is designed using the cascade theory. The effects of dynamic stall and flow curvature, in addition to solidity, design power coefficient, design tip speed ratio, design wind speed, cut-out speed, and blade supporting type (simple, overhang), have been considered. For the perf

Research on e-commerce adoption in SMEs has gained considerable attention in the past few years. However, most of them were conducted in developed countries such as USA, UK or Australia. This study attempts to understand ecommerce adoption amongst Malaysian SMEs, applying the persuasion stage of the Diffusion of Innovation Model by Rogers’s. The

Wife battering is a ground for divorce in the Malaysian Shariah Courts. Some husbands claim that it is their prerogative right to discipline their wives by corporal punishment based on their superficial understanding of the Qur’anic text 4:34 which seems to justify this argument. Some feminist organizations condemn this and allege that if physica

Selection of the airfoil is crucial for better aerodynamic performance and dimensions of a smaller-capacity SB-VAWT which can compete with conventional energy sources in niche markets like urban areas and off-grid remote applications for diversified applications. Airfoil related design changes also have the potential for increasing the cost effecti

This paper will discuss the present integration of sustainable features in a self-contained residential development in the growing urban density in Malaysia - consisting of 36 units semi-detached and 4 units terrace houses – within the constraints of commercial viability of such a project. The projects features the layout planning for green-share
