Numerical analysis of GNP/Ag Die-Attach adhesives with different thermal conductivity
(Universiti Malaysia Perlis (UniMAP), 2022-03)
The thermal conductivities of a multilayer model of GNP/Ag hybrid die-attach material are
explored using steady-state thermal modeling. The heat flux in multilayer GNP/Ag hybrid
structures is shown to be highly layer ...
Parametric analysis of sound transmission loss in a rectangular duct attached with resonator silencer
(Universiti Malaysia Perlis (UniMAP), 2022-03)
Noise is an existing problem that exist in the environments produced from vibrating sources.
In general, the common solutions for noise control are: (1) redesigning the system the system
for instance increasing wall ...
Electroencephalogram (EEG)-based systems to monitor driver fatigue: a review
(Universiti Malaysia Perlis (UniMAP), 2022-03)
An efficient system that is capable to detect driver fatigue is urgently needed to help
avoid road crashes. Recently, there has been an increase of interest in the application of
electroencephalogram (EEG) to detect ...
Effect of light intensity on indoor temperature and air velocity: a simulation study
(Universiti Malaysia Perlis (UniMAP), 2022-03)
It is essential to understand the factors influencing thermal responses to improve human
comfort and properly reduce energy consumption. It has been confirmed that parameters
unrelated to the thermal environment can ...
The effect of porous materials on temperature drop in a standing wave thermoacoustic cooler
(Universiti Malaysia Perlis (UniMAP), 2022-03)
Thermoacoustics is a principle of sciences that offers an alternative solution for cooling system with a technology that is green and sustainable. The thermoacoustic energy conversion takes place mostly within the area of ...
Mineralogical characterizations of Langkawi Ilmenite ore for carbothermal reduction
(Universiti Malaysia Perlis (UniMAP), 2022-01)
The mineralogical characterizations of Langkawi’s ilmenite were investigated using XRD, XRF and SEM/EDS for morphological analysis. The minerals mainly consist of the phases of FeTiO3, Fe3O4 and TiO2 by Rietveld refinement, ...
Hydro-mechanical properties of cement mortar using bentonite as partial cement replacement
(Universiti Malaysia Perlis (UniMAP), 2022-07)
With the present emphasis on sustainability, it is critical to produce ecofriendly building materials aiming to reduce carbon dioxide emissions from cement manufacturing process. Bentonite is one of the most essential ...
The impact of working gas on heat transfer performance of tube banks heat exchanger in a thermoacoustic system
(Universiti Malaysia Perlis (UniMAP), 2022-03)
Thermoacoustic system is a system introduced as an alternative technology for refrigerators
or heat engine because it uses environmentally friendly gases as a working medium.
Thermoacoustic system usually uses noble ...
Optically enhanced N doped ZnO amorphous nanostructures grown by low cost ultrasonicated sol–gel route
(Universiti Malaysia Perlis (UniMAP), 2022-07)
N doped ZnO amorphous nanostructures with excellent optical properties were grown by the ultrasonicated sol-gel route. The samples were characterized using structural, morphological and optical studies. XRD patterns confirmed ...
Correlation between surface texturing on pre-plated leadframe and delamination phenomenon in automotive packaging
(Universiti Malaysia Perlis (UniMAP), 2022-07)
Poor adhesion between mold compound and leadframe in integrated circuit packaging for automotive devices can cause serious reliability issue and degrade the package quality. This study aims to evaluate and understand the ...
