Attenuation of ultrasound waves varies with tissue composition, hence its estimation offers great potential for characterization and diagnosis staging pathology. We recently proposed a method that allows to spatially reconstruct the distribution overall attenuation in based on computed tomography, using reflections from passive acoustic reflector. This requires standard transducer operating pul...

The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...

The Functional Electrical Stimulator design using monophasic spike-exponential waveform was proposed and described in this study. The monophasic square waveform has benefit in generating an action potential, but it could cause side effects such as toxic caused by the electrode polarization. The square waveform signal which the frequency and pulse width could be modulated was manipulated to be t...

Due to the growth of high-frequency signal usage in recent years, limiting the coverage of these signals in the common household environment has become an issue. The paper proposes a set of simulations and measurements aiming to determine the attenuation of the GSM and Wi-Fi signals as they pass through different types of construction materials. Using MATLAB Simulink© and experimental studies u...
