There are various ways to impose a potential variation in time, and subsequently a series of voltammetric methods. Cyclic voltammetry relies on linearly scanning the potential in time, observing a triangular waveform variation [1-3]. Differential pulse voltammetry is based on two samplings of the current intensity for each potential pulse: one measurement before applying the pulse, and the seco...

Extremely hard materials can be easily machined by Electrical Discharge Machining process due to its thermal erosion nature. In this process, the amount of material removed is directly proportional to the discharge current. Due to the stochastic nature of the thermal erosion process, the discharge current is varied for every applied electrical pulse. It results in different levels of material r...

this paper presents a novel control approach used in shunt active power filter based on variable structure control combined with random pwm technique (rvsc) that provides robust, fast, and more favorable performance for active power filter. this control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

We wish to comment on the assertion that a “short pulse width widens the therapeutic window of subthalamic neurostimulation,” as reported by Reich et al. In that publication, the authors defined “therapeutic window” in deep brain stimulation as the difference in current between the onset of full rigidity control and the onset of adverse muscle contractions at a given pulse duration. They determ...

We study the discrete-time Poisson channel under the constraint that its average input power (in photons per channel use) must not exceed some constant E . We consider the wideband, high-photonefficiency extreme where E approaches zero, and where the channel’s “dark current” approaches zero proportionally with E . Improving over a previously obtained first-order capacity approximation, we deriv...

We briefly summarized several new stimulation techniques. There are many new methods of human brain stimulation, including modification of already known methods and brand-new methods. In this article, we focused on theta burst stimulation (TBS), repetitive monophasic pulse stimulation, paired- and quadri-pulse stimulation, transcranial alternating current stimulation (tACS), paired associative ...

A propagation of pulse generated by an electric dipole is studied. A general formula for the electric field, which is uniformly valid for large distance and time, is presented. Fourier transform, stationary phase and simple contour integration methods are applied. 1. CURRENT PULSE AND FOURIER TRANSFORM Electric dipole is excited by a current I(t) = I0f(t) where f(t) is a pulse. The Fourier tran...
