This paper describes a silicon implementation of an Arti cial Neural Networks based on Coherent Pulse Width modulation techniques. Synapses use current generators controlled by an input Pulse Stream. Net charge generated is the product of synaptic current by pulse width. Neurons accumulate synaptic contributions and convert internal activation into an output Pulse Stream. A system optimized for...

in the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (hmde) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. the method is based on accumulation of thiosemicarbazide on mercuryelectrode. the potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...

In cricket calling songs, pulse rate is often the feature that allows females to home on the songs of conspeciÞc males while ignoring those of other species. A previous study of the sibling speciesGryllus rubensScudderandG. texensisCade&Otte fromwesternFlorida showedunexpected effects of developmental conditions and parental generation on the pulse rates of their songs. The current study tested...

We report results of experiments in which pulses of helium vapor are produced by a current pulse in a chromium film covered with superfluid helium at around 0.3 K. The pulses were detected by a titanium bolometer operating at 0.47 K. The shape of the detected signal is a strong function of the power of the initiating current pulse. For low powers the signal from a single current pulse also cont...

A sound-induced sympathetic tone has been used as an index for orienting responses to auditory stimuli. The resting testosterone/cortisol ratio is a biomarker of social aggression that drives an approaching behavior in response to environmental stimuli, and a higher testosterone level and a lower cortisol level can facilitate the sympathetic response to environmental stimuli. Therefore, it is p...

The torque generated by the transfer of spin angular momentum from a spin-polarized current to a nanoscale ferromagnet can switch the orientation of the nanomagnet much more efficiently than a current-generated magnetic field and is therefore in development for use in next-generation magnetic random access memory MRAM . Up to now, experiments have focused on spin-torque switching driven by simp...

To improve the static performance, dynamic and current balance of a current-source PWM rectifier with multi-modules, comprehensive control method passivity-based is proposed in this paper. Current control, which based on AC voltage sequencing, has advantages being easy to implement not limited by number modules. Mathematical modelling, controller design, simulation verification were conducted s...
