When the eyes were given maximum disparity, a good relationship was found between visual fatigue and the static or dynamic parameters of vergence and accommodation, as well as physiological signals and subjective evaluation value. The common experimental paradigm of asthenopia is to give the dynamic and repetitive stimulus. Therefore, the current research was proposed to devise a static and sustained...
This paper prepents monolithic microwave integrated circuits (MMIC) employing large size resonant tunneling diode (RTD) with high power at high frequencies. This is achieved by proper design of the resonating inductances which are realized by shorted microstrip transmission lines with low characteristic impedances (Z0 = 10.4 Ω). Two oscillators were fabricated using photolithography. Oscillation frequencies...
Excitation source with multi-frequency sinusoids is of importance for bioimpedance spectroscopy (BIS) measurements. This paper describes a novel and simple method to synthesize multi-frequency sinusoids with 2nth primary harmonics based on Walsh functions. The synthesis mechanism is presented detailedly, and after analyzing the Fourier series expression of the periodic signal, the expression of the...
A magnetic pulse compression topology is presented which does not contain external remagnetization circuits that are commonly used in magnetic compressors. Principle of operation of the compressor is described. A two stage compression system is designed based on the new MPC topology. To understand the magnetic switch operation in great detail and to model the performance of magnetic switches, a Pspice...
