Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc

Coherence in text and hypertext

Abstract:

The concept of text coherence was developed for linear text, i.e. text of sequentially
organized content. The present article addresses to what extent this concept
can be applied to hypertext. Following the introduction (section 1), I will define
different aspects of text coherence (section 2). I will then explain the importance
of the sequential order of text constituents for coherence-building, as explored by
empirical studies on text comprehension (sectio ....etc

ppt working principle of pulse tube refrigerator

Abstract

The working fluid for the pulse tube refrigerator is Helium, which is non-toxic to humans and harmless to the environment. The Pulse Tube Refrigeration unit offers a viable alternative to units that currently require CFC and HCFC working fluids. Pulse Tube Refrigerators can be operated over wide range of temperatures. These units can be used in numerous space and commercial applications, including food freezers freeze dryers. It can also be used to cool detectors and electronic devices ....etc

Optical Coherence Tomography (OCT)

Introduction
Optical Coherence Tomography (OCT) is an imaging technique that is similar in principle to ultrasound, but with superior resolution. It relies on exposing a sample to a burst of light and then measuring the reflective response from different depths and is therefore capable of scanning non-invasively beneath the surface of the sample. In ultrasound imaging, it is relatively easy to measure the time delay of each reflected packet. However, for light pulses, interferometry must be used to measure ....etc
