Thermal comfort assessment at parcel and logistic industry: A field study in Malaysia
(The Institution of Engineers, Malaysia (IEM), 2011-09)
This paper presents the workers thermal sensation votes and perception of the thermal environment in air conditioning at one
of the workspace in Malaysian parcel and logistic industry. The environment factors examined was ...
Flow streamlining for cooling improvement in ventilated brake disc using CFD as design tool
(The Institution of Engineers, Malaysia (IEM), 2011-09)
This paper presents experimental and Computational Fluids Dynamics (CFD) investigations of the flow and heat
transfer in ventilated brake discs. The validation CFD model is done using the straight blade (baseline design) ...
Zero discharge composting of palm oil mill wastes
(The Institution of Engineers, Malaysia (IEM), 2011-09)
The conventional methods of disposal and treatment of oil palm mill wastes are not environmentally friendly and they result in
large amount of Greenhouse gases being emitted into the atmosphere. The technical feasibility ...
The performance of a prefaricated vertical drain trial embankment
(The Institution of Engineers, Malaysia (IEM), 2011-09)
Two fuel scale trial embankments were constructed to a height of 3.65 m over the soft marine clay at Juru, Butterworth, Pulai Pinang. One of the embankments was improved using prefabricated vertical drain (PVD), and the ...
Reactions of used motor oil and residual oil using mesoporous MoAI₂O₃ catalyst
(The Institution of Engineers, Malaysia (IEM), 2013-06)
In the present study, mesoporous Mo-based catalysts of different pore size ranges were synthesized and investigated for its hydrocracking activity. Catalyst pore size has been considered a property affecting the_mass ...
Physical, geotechnical and morphological characteristics of peat soils from Sarawak
(The Institution of Engineering, Malaysia (IEM), 2011-12)
In Malaysia, Sarawak has the largest area of peat-land in the country, covering approximately 1.66 million hectares. With the
rapid industrialisation and population growth, construction is scheduled almost all over the ...
Numerical and experimental study of shock/turbulent flow interaction – A code validation test
(The Institution of Engineers, Malaysia (IEM), 2011-12)
A numerical code has been developed to solve the shock/turbulence interaction using grid adaptation technique. For the
code validation test, shock wave propagations through nozzle are studied experimentally and numerically ...
A multilevel multiplexing technique for high speed fiber optic communication systems
(Institution of Engineers, Malaysia (IEM), 2011-12)
In order to explore the potential of optical multilevel signaling for high speed optical fiber networks, a novel multilevel
multiplexing technique is demonstrated. Three users, each with data rates of 10 Gb/s were ...
Strength and deformation characteristics of cement treated soft Bangladesh clays
(Institution of Engineers, Malaysia (IEM), 2011-12)
The strength and deformation characteristics of cement treated soft Bangladesh clays are evaluated through a series of
experimental investigations. Based on the rate of strength development, the unconfined compressive ...
A metallurgical study of spot weld growth on mild steel with 1mm and 2mm thicknesses
(The Institution of Engineers, Malaysia (IEM), 2011-12)
Resistance Spot Welding (RSW) is an important welding technology for joining two or more metals in various manufacturing
industries. For instance, to date a car may contain an average of 3000-4000 spot weld joints and the ...
