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...

A unified framework is developed in which to compare several techniques for synthesizing sounds with desired spectra, using AM, FM, waveshaping, and pulse width modulation.

Sensitive Arecibo observations provide an unprecedented ability to detect nulls for an accurate pulse-modulation quelling (PMQ) analysis. We demonstrate that a number of conal pulsars show “periodic nulling” similar to the phenomenon found earlier in pulsar B1133+16.

This paper is a simple and systematic approaches to the design and analysis a pulse width modulation (PWM) based sliding mode controller for buck DC-DC Converters. Various aspects of the design, including the practical problems and the proposed solutions, are detailed. However, these control strategies can't compensate for large load current and input voltage variations. In this paper, a new co...

In this paper, we propose a software-oriented method for generating multiple pulse width modulation channels from the parallel port of a computer without using any additional interface. We have developed an algorithm to modulate different signals that may come from different sources and generate the corresponding modulated signals on the parallel port of a computer. Our approach is tested in re...

IR Sensor Based Fiber Communication System For Stepper Motor Control Using PWM Controlling Sequence/Signal. The Circuit Is Based On Optical Transmission & Can Be Operated With High Speed Fiber Connection or Properly Aligned IR Wireless Link.

This paper describes a complete silicon implementation of an Arti cial Neural Network based on Coherent Pulse Width modulation techniques. A chip set with di erent neural functions has been designed, manufactured and tested. Neural circuits have been optimized for lowest computation energy and highest recon gurability.

In view of X-ray Free Electron Laser (XFEL) intensity prospects, we reviewed the past and recent work in view of amplification of powerful XFEL laser pulse to achieve intensity in the regime of high field science. We report here some of the relevant work investigated in this field and predicted further scalings and possibilities for XFEL pulse amplification.

In this paper, a SEIRS epidemic model with two delays and pulse vaccination is formulated. The pulse vaccination strategy has been applied to control the spread and transmission of an infectious disease. The global attractivity of infection-free periodic solution are explored. We show that the disease is eradicated when the basic reproduction number is less than unity.
