Sustainable Design & Product and Health & Safety Awareness among Public University Students
No full textIn this article, the focus is on understanding the awareness of sustainable design & product and health & safety among engineering and architectural students at university levels as these young graduates are representative of the workforce. This survey was conducted at five public universities in Peninsular Malaysia. On average, the majority of respondents provided positive responses (more than 80%) on the needs of sustainable design & product and health & safety aspects in their workplaces. These figures bode well for such an ambitious country to be on par with developed countries. It is also noteworthy to highlight that a significant portion who are not comfortable with investing with sustainable features.Â

Burr Height as Quality Indicator in Single Shot Drilling of Stacked CFRP/Aluminium Composite
No full textIn drilling metallic parts, burr height is one of the quality indicators that is used for hole quality assessment, and burr height need to be minimized for best hole quality. This is important because the induced exit burr height usually causes serious problem for further assembly of the stack up during the riveting and fasteners installation. This paper aims to establish an appropriate choice of drill geometry and drilling parameters to achieve a minimum or eliminate the burr height formation when drilling stacked Carbon Fibre Reinforced Plastic (CFRP)/aluminium 7075 T-6 composite in a single shot drilling process. The two levels of fractional factorials method was used to determine the optimum setting that give minimum burr height and the percentage of significance for each parameter in drilling a stack up materials was further analysed. The results revealed that burr height formation for stack up materials can be minimized at 15° of helix angle, 8° of primary clearance angle, 130°of point angle, 30° of chisel edge angle at spindle speed 2600 RPM and 0.05 mm/rev. A minimum burr height of 133.62 µm was found at these optimized combinations of parameters.</jats:p
MHD Free Convection and Mass Transfer Flow through a Vertical Oscillatory Porous Plate with Hall, Ion-slip Currents and Heat Source in a Rotating System
No full textAbstractUnsteady MHD free convection and mass transfer flow through a vertical oscillatory porous plate with hall, ion-slip currents and heat source in a rotating system are studied. The governing equations of the problem contain a system of non-linear coupled partial differential equations. The coupled non-linear partial differential equations are solved by explicit finite difference method and the numerical results have been calculated by Compaq Visual 6.6a. For good accuracy, stability and convergence analysis have been analyzed. The results of this investigation are discussed for the different values of the well-known parameters and are shown graphically
A survey on engineering ethics and technological advancement among Malaysian public university students
No full textA survey at five public universities in the Peninsular Malaysia has been conducted to get a clearer statistics of students' understanding of engineering ethics, technological advancement and safety. Ethical issues, sometimes rampant, occur in the public and private sectors as well as in the society, these have caused poverty in the long run and to some extent the environment. The survey has been conducted over a period of almost one year with the respondents being the third and fourth year engineering and other technical equivalent students. Very significant number of participants i.e. 92.1% indicated their agreements that there exist ethical issues in the country and there are tremendous rooms for improvement. 89.0% respondents indicated that our ambitions towards a developed nation is possible if engineers and technical expertise in the government and private sectors embrace ethics awareness in their dealings. Responses of similar magnitudes also reveal that a lot of man-made accidents and disasters are avoidable i.e. if ethical awareness are put into actions
