A finite element model is proposed to determine the residual strength and the evolution of damage area of indented sandwiches structures with Nomex honeycomb core and metallic skins indented by a spherical indenter under longitudinal compression load (CAI). The honeycomb is represented by a grid of non-linear springs which its behavior law is obtai

بما جرى على أرضها بين المهاجرين الأولين من المسلمين، والملك العادل النجاشي الذي يعد هو الأوحد من بين أقرانه من ملوك الأرض في حينه تقبلا لدعوة الإسلام، وفي هذا عظيم الشرف لتلك القارة التي انفرد

Activated carbons derived from oil palm empty fruit bunches (EFB) were investigated to find the suitability of its application for removal of phenol in aqueous solution through adsorption process. Two types of activation namely; thermal activation at 300,500 and 800°C and physical activation at 150°C (boiling treatment) were used for the producti

This paper presents how manufacturing engineering curriculum in International Islamic University Malaysia (IIUM) is designed to prepare its graduates fit for manufacturing industry. Since the inception in 1994, IIUM has been preparing its students through specialization in manufacturing engineering and precision machining. After 10 years, the curri

Bioethanol production was carried out by solid state bioconversion method utilizing lignocellulosic material, rice straw (RS) as substrate with the aid of mixed cultures of Saccharomyces cerevisiae, T. harzianum and P. chrysosporium. The mixed culture of the microorganisms was established to investigate their compatibility for direct bioconversion

The adsorption capacity of activated carbon produced from oil palm empty fruit bunches through removal of 2,4-dichlorophenol from aqueous solution was carried out in the laboratory. The activated carbon was produced by thermal activation of activation time with 30 min at 800°C. The adsorption process conditions were determined with the statistical

This paper discusses the investigation of geometrical integrity of micromold cavity produced by focused ion beam (FIB) sputtering slice by slice. Parabolic shaped micromold cavity was chosen as an example. Preliminary experiments were carried out to characterize the machine and select the optimum process parameters such as beam current, pixel spaci

A solid state fermentation method will be carried out for the production of citric acid from empty fruit bunches (EFB) by employing the potential fungus Aspergillus niger (A106). Statistical optimization was carried out in terms of media composition and fermentation time by central composite design (CCD) to evaluate the polynomial regression model

This paper discusses the application of conventional wire electrical discharge machining (WEDM) for fabrication of miniaturized components using low pulse energy. The surface finish of the fabricated microparts was investigated for different level of discharge current at constant gap voltage and pulse-on time. Miniaturized gears of 3.58 mm outside

This paper highlights the importance of providing scientific basis for traditional technologies.
