A finite element model is proposed to determine the residual print of sandwich structures with Nomex honeycomb core and metallic skins indented by a spherical indenter and to simulate its behavior when this indented structure is subjected to lateral compressive loading (known as CAI/ Compression after impact). The particularities of this model rely

Regional maps and equations for the magnitude and frequency of 1, 7 and 30-day low flows were derived and are presented in this paper. The river gauging stations of neighbouring catchments that produced similar low flow frequency curves were grouped together. As such, the Peninsular Malaysia was divided into seven low flow regions. Regional equatio

The effect of water vapor on high temperature oxidation was studied based on Wagner’s theory of binary alloy oxidation. The oxidation of Fe-Cr alloys was carried out at 1073K in dry and humid conditions. The oxidation was conducted in a closed apparatus at 1073K and the oxygen partial pressure of 1:1 � 10�14 Pa, which was fixed by a Fe/FeO bu

the microstructural features of the weld section which are controlled by the energy input and heat transfer factors. The welding current, travel speed and the material property govern these parameters. However, the specific influence of range of heat input rates on the microstructural features of FSS weld is hardly reported. This paper reports the

The total energy input and heat transfer factors influence the after-weld microstructural features and hence properties of the joint. Low heat input has been suggested for fusion welding in order to avoid unfavourable grain morphologies in the welds. Also, the weld cooling cycle is crucial in the control of weld microstructures, particularly the ti

HSBL University College is one of the privately runned institutions of higher learning in Malaysia which offers, among others, various programs in Economics, Accounting and Business Administration. A recent survey conducted by the Faculty of Business (FB) of HSBL found that the students were not fully satisfied in the teaching and learning system o

The fast growing palm oil industry in Malaysia generates, amongst other wastes, Empty Fruit Bunch (EFB) which consists of cellulosic materials. It is one of the major sources of Greenhouse Gases (GHG). However, the bioconversion of cellulosic materials in EFB, a renewable biomass, to valuable products will be the solution to the disposal problem an

Chemical vapour deposition (CVD) reactor is one of the processes commonly used for carbon nanomaterial (CNM) production. This method is economical and provides high yield of good quality CNM. However, improvement of the CVD reactor system was necessary due to its long time requirement to complete each batch of production. A two-stage CVD was design
