Prosthesis hand is an artificial device which replaces missing hand because of human's hand may lost by trauma, disease or defect. From last decade, some researchers have been studying to invent and develop artificial hand. One of the most important step of bionic upper limb is developing surface electromyography (sEMG) signal analyzing methods. This pilot study is aimed to examine de-noising efficiency...
Electromyography (EMG) is a signal which produces from motor units (MUs) in the muscles during contraction activities. By detecting EMG, it can show muscle contractions and body members' movement such as hand, eyes and legs. Monitoring and analyzing these signals from the skin which called Surface EMG (SEMG) required some essential components, for example electrode, data acquisition (DAQ) system and...
Recording of biopotential signals is uneasy as interference and noise can come from the preparation of the subject, environment setting and other biological signal. The circuit design in acquisition system must good and meets specification as is not distort original signal and safe to patient. Classic design of biosignal acquisition system usually use third electrode as reference potential. The third...
In this paper, we propose a new design of Fiber-to-the-Home (FTTH) network based on Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA). The FTTH network based on SAC-OCDMA system is tested by employing the Dynamic Cyclic Shift (DCS) code. Whereas, the DCS code is selected due to reduced and mitigates the effect of Multi Access Interference (MAI) in comparing with existing...
The 5850–7075MHz band is profoundly utilized for the fixed service such as Terrestrial Systems (TS) and microwave access (WiMAX) in various parts of the world. Nowadays, the High Altitude Platform System (HAPS) became a recognized system in this band. Therefore, terrestrial links are one of the most considerable interference with the HAPS gateway (HAPSGS) links. Hence, the legitimated interference...
A new code family for Spectral Amplitude Coding Optical Code Division Multiple Assess (SAC-OCDMA) system has been proposed in this paper. The new code family we call it Dynamic Cyclic Shift (DCS) code. The DCS code has many advantages. However, the DCS code can be generated without code parameter limitation. In addition, the shorter code length and variable cross correlation (λc ≤ 1) of the DCS code...
This paper introduce the adaptive kalman filter to modeling dynamic background for background subtraction. Background subtraction is a method to identify object and famous used in moving object segmentation. In this paper we also investigate a comparison study on Gaussian subtraction method, frame differencing method and approximate median method. The detection of object will be shown in the result.
Gel electrophoresis (GE) is an important tool in genomic analysis. It is a process of DNA, RNA and protein molecules separation using electric field applied to a gel matrix. This paper describes the image processing techniques applied on GE image to segment the bands from their background. Numerous pre-processing steps are applied on the image prior to the segmentation technique for the purpose of...
Chatter is one of the unwanted noises generated during wiper operation. It is a low frequency and self-excited vibration that is often generated before and after the wiper reverses direction. This leads to poor visibility and an annoying sound to the driver and passengers. This paper intends to propose a control technique that is capable of reducing chatter noise and vibration in the automotive windshield...
