This paper reports on the introduction of microelectromechanical systems (MEMS) or microsystem technologies courses into the manufacturing engineering program at the International Islamic University Malaysia (IIUM). It includes both, undergraduate and postgraduate courses with MEMS topics. At present, topics and courses are included in the undergra

In this paper, various fabrication techniques for micromold cavity are reviewed and discussed. Silicon and lithography based fabrication were being used for years for the fabrication of micromold cavity. In the later stage direct fabrication techniques such as focused ion beam, micro electro discharge machining, laser micromachining, tool based mic

Immobilized enzymes, such as lipases, have diverse applications including chemical, fuel, pharmaceutical and food processing industries. In this study, commercially available lipase extracted from Aspergillus niger has been immobilized on (MWNTs). The enzyme was bound to carbon nanotubes by covalent bonding, in the presence of N-(3-dimethylaminopro

In this paper the machining condition to achieve nano surface roughness in finish cut micro electro discharge milling was investigated. The effect of feed rate and capacitance were studied on average surface roughness (Ra), and maximum peak-to-valley roughness height (Ry). Statistical models were developed using three-level twofactor experimental d

This paper reports the influence of micro end milling process parameters on surface roughness of beryllium copper alloy. A number of microchannels were fabricated in order to characterize the process parameters influencing surface roughness. Two-level four-factor statistical models were developed to predict the average (Ra) and peak-to-valley (Rt)

This paper discussed the investigation of the burr formation in micro end milling process on stainless steel. Thus, formation of burr after machined by micro end milling process was investigated and analyzed. Tungsten carbide end mill cutting tool of diameter 500 μm was used with depth of cut of 200 μm. A number of microchannels were machined to

This paper presents the results of experimental investigations conducted on a vertical machining centre (VMC) to ascertain the effectiveness of brazed circular polycrystalline cubic boron nitride (PCBN) inserts in end milling of hardened steel AISI D2 (60-62 HRC), under room temperature and workpiece preheated conditions. Comparison was made in ter

Objective: To analyse difficulties and outcome of pediatric laryngotracheal reconstruction using cartilage graft for severe subglottic stenosis Methods: Retrospective analysis of all laryngotracheal reconstruction since the past 3 years from 2003-2006. Results: Seven cases altogether, age ranging from one to thirteen years. All had grade iii and ab

This study examines the general perceptions of women towards their roles, their interpretation of progress, as well as the facilitating factors and barriers to their progress. Questionnaires were distributed to 1,000 Malay women in Malaysia from rural and urban areas, from various age and income groups. Interviews were also carried out on the selec

Purpose – This paper aims to examine the long-run and dynamic behaviors of real wage-employment-productivity relationship, using Malaysian manufacturing data, and to determine which related labor theories are supported. Design/methodology/approach – Time-series econometric techniques, which include stationarity and cointegration tests, vector e
