Implementation of Sawtooth Wavelet Thresholding for Noise Cancellation in One Dimensional Signal
(Universiti Malaysia Perlis (UniMAP), 2019-01)
Wavelet families have different statistical characteristics and specifications which give
them a different response against the same signal or image when they are used for a
certain task such as signal denoising. Therefore, ...
Numerical Simulation and Comparative Assessment of DG-HEMT Device for High-frequency Application
(Universiti Malaysia Perlis (UniMAP), 2019-01)
The main objective of this paper is to investigate the DC and AC performances of GaN/InGaN/GaN Double Gate High Electron Mobility Transistor (DG-HEMT) based on innovative materials III-V in particular III-N materials ...
The Influence of Nitrogen Pressure on the Structure of a-CNx Thin Films Prepared by PLD Method
(Universiti Malaysia Perlis (UniMAP), 2019-01)
The structure of amorphous CNX thin films have a variety of chemical bond, and studies on these bonds ratios is very important because these ratios determine the appropriate technical use of these films. Therefore, this ...
Active Control of Silver Nanostructure Aggregates for Ultrahigh Sensitive SERS Detection of Organic Molecules: Single Molecule Approach
(Universiti Malaysia Perlis (UniMAP), 2019-01)
P-type and n-type of Porous Silicon (PSi) substrates have been prepared by electrochemical and photo-electrochemical etching processes, respectively. Unique morphological features of Psi were employed to synthesis efficient ...
Optimization of the Temperature Synthesis of Hydroxyapatite from Indonesian Crab Shells
(Universiti Malaysia Perlis (UniMAP), 2019-01)
Hydroxyapatite (HAp) [Ca10(PO4)6(OH)2] is a ceramic class of material widely used for
medical applications. The HAp has been synthesized from Indonesian crab shells using a
precipitation method at different temperatures ...
Examination of silver nanoparticles formation by laser ablation in organic liquids
(Universiti Malaysia Perlis (UniMAP), 2019-07)
Silver Nanoparticles (NPs) were prepared via pulse laser ablation in different organic liquids such as acetone, toluene, and cyclohexane. Particle size, optical and stability properties of synthesized colloidal Nanoparticles ...
Substrate temperature effects on optical properties and constants of ZnO
(Universiti Malaysia Perlis (UniMAP), 2019-07)
The preparation process of ZnO TCO (Transparent Conducting Oxide) thin films have been conducted in this paper. A Q-switched Nd:YAG laser of 7 ns duration and 1 joule of energy was utilized to perform the deposition process ...
Simulation of viscous fingering due to saffman-taylor instability in hele-shaw cell
(Universiti Malaysia Perlis (UniMAP), 2019-07)
We simulated the growth of the viscous fingers in a Hele-Shaw cell, a Laplacian growth, by a numerical solution. We solved a Laplace equation numerically with boundary conditions that indicated a pressure jumping due to ...
Studying the effect of synthesized Nano-Titanium Dioxide via two phases on the pseudomonas aeruginosa and portus bacteria as antimicrobial agents
(Universiti Malaysia Perlis (UniMAP), 2019-07)
The Titanium dioxide (TiO2) Nano-particles (NPs) is synthesized via the Sol -gel method by using titanium tetrachloride (TiCl4) as a starting material while varying the applied temperature in the range of (400-900)ᵒC. The ...
