Numerical modelling of reverse pulse cleaning on rigid ceramic filters
(The Institution of Engineers, Malaysia, 2005-03)Many industrial processes involve the generation of waste gases and particulates. Environmental legislation enacted as a result of government policy has compelled industry to pay a serious attention to the air pollution ... -
A generalised price-scoring model for tender evaluation
(The Institution of Engineers, Malaysia, 2005-03)This paper proposes a generalised price-scoring model derived from behavioural features of prospect theory for use in a tender evaluation program. It has the potential to overcome the limitations of existing price models ... -
Analysis of design parameter effects on vibration modes of a motorcycle drum brake and brake shoe using the finite element method
(The Institution of Engineers, Malaysia, 2005-03)The natural frequencies and vibration modes of the particular motorcycle drum brake and brake shoe have been determined using the finite element method. The results show that the drum brake has 42 mode shapes in the ... -
A study of the phenomenon of soil – reinforcement interaction
(The Institution of Engineers, Malaysia, 2005-06)The analysis and design of reinforced earth wall and retaining wall with reinforced backfill require the knowledge of the value of the coefficient of interfacial friction between soil and reinforcement. This coefficient ... -
Employing a failure criterion with interaction terms to simulate the progressive failure of carbon-epoxy laminates
(The Institution of Engineers, Malaysia, 2005-06)A failure criterion with the existence of coupling terms is employed to investigate the progressive failure in anisotropic laminated carbon-epoxy plates. The criterion is employed because it is developed recently. Moreover, ... -
