Water quality study of Timah Tasoh Lake in Perlis, Malaysia
(Trans Tech Publications Ltd., 2014)
Timah Tasoh Lake is surrounded by various types of land use activities ranging from industrial, agricultural and quarrying activities. These activities will affect the water quality and a threat to the ecosystem of the ...
A novel heuristic for optimization aggregate production problem: Evidence from flat panel display in Malaysia
(AIP Publishing, 2015)
This paper contribute to the flat panel display industry it terms of aggregate production planning. Methodology: For the minimization cost of total production of LCD manufacturing, a linear programming was applied. The ...
Underwater femtosecond laser micromachining of thin nitinol tubes for medical coronary stent manufacture
(Springer-Verlag, 2012-06)
Microprofiling of medical coronary stents has been dominated by the use of Nd:YAG lasers with pulse lengths in the range of a few milliseconds, and material removal is based on the melt ejection with a high-pressure gas. ...
Optimization of blending parameters and fiber size of kenaf-bast-fiber- reinforced the thermoplastic polyurethane composites by Taguchi method
(Hindawi Publishing Corporation, 2013)
“Kenaf-fibers- (KF-)” reinforced “thermoplastic polyurethane (TPU)” composites were prepared by the melt-blending method followed by compression molding. Composite specimens were cut from the sheets that were prepared by ...
Measurement and optimisation of residual tensile strength and delamination damage of drilled flax fibre reinforced composites
(Elsevier B.V., 2015-11)
The advent of natural fibre as reinforcement material for polymer composites has gained much attention in recent years. Since composite materials made of natural fibres exhibited good and comparable mechanical properties, ...
Productivity theory for industrial automated lines
(American Society of Mechanical Engineers (ASME), 2013)
The basic attributes of any industrial machines and systems are productivity rate and quality of products. Attributes of productivity are related to the theory of reliability let alone the theory of efficiency of machines. ...
PID controller tuning using evolutionary algorithms
(World Scientific and Engineering Academy and Society (WSEAS), 2012)
This paper presents the implementation of PID controller tuning using two sets of evolutionary techniques which are differential evolution (DE) and genetic algorithm (GA). The optimal PID control parameters are applied for ...
Improving the quality and productivity of molded parts with a new design of conformal cooling channels for the injection molding process
(John Wiley and Sons Inc., 2015)
In materials processing, quality and productivity are notably important and must be controlled for each product type produced. In the injection molding process, quality is measured as the extent of warpage of molded parts ...
Classroom comfort ability assessment: A case study
(Praise Worthy Prize S.r.l., 2012-03)
his study was conducted to evaluate the comfort level of an air-conditioned classroom at the School of Manufacturing Engineering campus using objective measurement, subjective assessment and Computational Fluid Dynamics ...
Catalytic dehydrogenation of methylcyclohexane (MCH) to toluene in a palladium/alumina hollow fibre membrane reactor
(Elsevier Ltd., 2013)
A compact multifunctional Pd/alumina hollow fibre membrane reactor (HFMR) has been developed and used for the catalytic dehydrogenation of methylcyclohexane to toluene. The developed HFMR consists of a thin and defect-free ...
