conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

For data processing in conventional phase shifting interferometry, Fourier transform, and least-squares-fitting techniques, a whole interferometric data series is required. We propose a new interferometric data processing methodology based on a recurrent nonlinear procedure. The signal value is predicted from the previous step to the next step, and the prediction error is used for nonlinear cor...

In this study, two types of direct interface capacitive sensors, self- and mutual-capacitance, were developed and compared experimentally. Electromagnetic Compatibility (EMC) tests-International Electrotechnical Commission (IEC) 61000-4-3, IEC 61000-4-4, IEC 61000-4-6-were applied in an accredited laboratory to measure the immunity of the sensors against radiated and conducted interference. The...

FM modulators have been with us since the time of Major Edwin H. Armstrong (sometimes known as the father of FM) and his classic 1936 paper on the subject. He first put down on paper the fundamental concept of a fixed center frequency that is varied per a constant deviation ratio that is independent of the frequency of the modulating signal. FM became very popular because much of the noise gene...

After a short review of the state-of-the-art, a new low-power differential threshold logic gate is introduced: split-precharge differential noiseimmune threshold logic (SPD-NTL). It is based on combining the split-level precharge differential logic, with a technique for enhancing the noise immunity of threshold logic gates: noise suppression logic. Another idea included in the design of the SPD...

the paper is based on a study conducted in three different industries on 84.4 on their employees to determine the effect of over all noise intensity, length of employment and rest periods among them. it was found that the mentioned factors have direct effect on the induced hearing loss among the exposed workers. high noise level and long period of employment adversely affect the hearing ability...

Differential Cascode Voltage Switch (DCVS) is a well-known logic style, which constructs robust and reliable circuits. Two main strategies are studied in this paper to form static DCVS-based standard ternary fundamental logic components in digital electronics. While one of the strategies leads to fewer transistors, the other one has higher noise margin. New designs are simulated with HSPICE and...
