Reactively sputtered copper indium sulfide (CIS) chalcopyrite semiconductor has been actively studied as the potential absorber layer for solar cell thin film application. Using sputtering technique however could result in the formation of several types of defects for example microscopic defects. Microscopic defects are formed within the absorber layer due to the formation of pinholes after surface...
The revolution of modern radio communication application such as radar, electronic warfare and signal intelligence using SDR technology has open an interest among researchers to adopt the technology in wireless communication system. This paper is focused on mechanisms and methodology to implement a low complexity SDR transceiver using Simulink, Matlab and Xilinx for FPGA environment. In this design,...
Face recognition system is widely used for human identification due to its capability to measure and subsequently identifies human identification especially for security purposes. This paper presents the development of Graphical User Interface (GUI) based on face recognition system and Peripheral Interface Controller (PIC) as an input/output carrier to switch on/off magnetic lock for door lock security...
In Malaysia, Halal Certificate can only be issued by Jakim. For the time being, there is no specific method to verify authentication of Halal Certificate displayed at food or service premises. Watermarking technique however, offered a solution for authenticity of the data and copyright protection. In this paper, an investigation on perceptual and robustness of least significant bit (LSB) digital watermarking...
The growth of media communication industry and demand of high quality of visual information in modern age has open an interest to researcher to develop varies method of image denoising based on DWT. The visual information transmitted in form of image is naturally corrupted by Gaussian noise which is classical problem in image processing. This additive random noise can be removed using wavelet denoising...
