Ability of wavelet transform in accessing time and frequency information at the same time make it widely used in analyzing bio-signals like electromyography (EMG). Discrete wavelet transforms (DWT) and stationary wavelet transform (SWT) are examples of analysis based on wavelet. Both analyses are based on decomposition technique and splitting signals into few frequency band. The different is DWT will...
To obtain a high-quality surface electromyography (EMG) recording, the signal must be acquired as far as possible from the muscle innervation and tendon zone. This study presents a technique to indicate better electrode positions for surface EMG of the upper limb muscles during wrist extension and flexion. Ten volunteers participated in this research. Surface EMG signals were collected from flexor...
This article discusses the optical-SNR variation of Stokes lines in Brillouin-Raman fiber laser. This variation is partly attributed to the cavity modes interaction through intraline-FWM residing the same spectral width. The worst OSNR is obtained at 650 mW Raman pump power (RPP) and 1555 nm Brillouin pump wavelength (BPW). The improvement is obtained for the RPP beyond 650 mW.

Currently, the advancement in Ultra-Wide Band (UWB) technology has caught the attention of many researchers to explore it given that its ability to support higher data rate with low transmission power. In spite of this, its capability to share the frequency spectrum with current narrowband and wideband radio services raises interference concerns for radio services. This study concerned with the effect...
