Effect of discharge power on the properties of GaN thin films on AlN-(002) prepared by magnetron sputtering deposition
(Universiti Malaysia Perlis (UniMAP), 2020-07)
Aluminum nitride (AlN) and gallium nitride (GaN) thin films were grown on silicon (Si) substrates using the conventional RF magnetron sputtering plasma deposition system. The growth rate of GaN increased as the deposition ...
Review on strain sensors for detection of human facial expressions recognition systems
(Universiti Malaysia Perlis (UniMAP), 2020-07)
Facial expression plays an important factor in human communication which helps us to understand the intentions and emotions of others. Generally, people infer the emotional states of other people such as fear, sadness, joy ...
Structural and morphological properties of Cu1-xAlxO nanostructures prepared by sol-gel method
(Universiti Malaysia Perlis (UniMAP), 2020-07)
In this study, the sol-gel process has been adopted for the synthesis of Cu1-xAlxO nanostructures (0≤ x ≤ 0.90, in steps of 0.10). The system revealed pure CuO phase with monoclinic structure. Al2O3 phase and copper oxide ...
Improving the optical properties of porphyrin ring with different substitutions: As candidate using in photosensitizer
(Universiti Malaysia Perlis (UniMAP), 2020-07)
In this research, different donor and acceptor substitutions were employed in attachment with porphyrin molecule and the optical properties improvement of it was studied. It was shown that the substituted porphyrin formation ...
Optical fibre sensor using frequency beating technique
(Universiti Malaysia Perlis (UniMAP), 2020-04)
In this paper, a new method to realize the optical fibre sensor using an optical heterodyne technique (OHT) is proposed and numerically demonstrated. In this method, the bandpass filter (BPF) was utilized as a reference ...
Synthesis and study the structural and magnetic properties of cobalt substituted strontium hexaferrite
(Universiti Malaysia Perlis (UniMAP), 2020-04)
A sol-gel auto combustion approach was used to synthesize Co2+ substituted M-type strontium hexagonal ferrite with the chemical formula Sr1-xCoxFe12O19 (x=0.0, 0.25, 0.50 and 0.75). X-ray Diffraction (XRD), Field Emission ...
Digital fringe projection system for round shaped breast tumor detection
(Universiti Malaysia Perlis, 2020-01)
The digital fringe projection has been widely used in the field of surface imaging however
its application in the field of body imaging especially for human breasts is still quite
limited. Currently, the common imaging ...
