COMPUTER SMPS POWER SUPPLY
A power supply is the heart of the heart of the computer system. As a human being needs proper circulation of the blood for the human body to stay alive and work, a computer need a well regulated 5 volt and 12 volt DC power supply for the proper functioning of its various parts. These DC power are supplied to the computer by the power supply. As, without the proper functioning of a heart the human body can not work, without a good and proper power supply the computer system can not do an ....etc

1. ABSTRACT

microRNAs are small, regulatory ssRNA molecules involved in post-transcriptional gene silencing. Numerous miRNAs have been implicated in different types of cancers. The aim of this study is to create a bipartite graph connecting miRNAs and different cancers. We intend to identify miRNA hubs that are implicated in a large number of cancer types. Studying the function of such hub miRNAs is likely to shed light on the common pathogenesis mechanisms shared across the various cancer types .A combination of li ....etc

BACKGROUND

The significance of power factor (PF) correction is reflected in the large number of documents addressing this subject, in the engineering design effort, and in the numerous industrial plants that manufacture equipment for the control of reactive power and filtering of current harmonics . Some of the benefits derived from correct PF adjustment are:
1. reduced energy loss;
2. released generation, transmission, distribution, and substation cap ....etc

ABSTRACT
The objective of this project is to design an embedded system which can control appliances remotely. This project is designed to study the basic implementation of DTMF (Dual Tone Multi Frequency).
The DTMF signal is composed of high frequencies & low frequencies. Each key is assigned a low frequency and a high frequency. When a particular key is pressed, the frequencies those are specific to that particular key are transmitted. Therefore, no two keys will have a same set of low & high frequencies ....etc

POWER SUPPLY:
The input to the circuit is applied from the regulated power supply. The a.c. input i.e., 230V from the mains supply is step down by the transformer to 12V and is fed to a rectifier. The output obtained from the rectifier is a pulsating d.c voltage. So in order to get a pure d.c voltage, the output voltage from the rectifier is fed to a filter to remove any a.c components present even after rectification. Now, this voltage is given to a voltage regulator to obtain a pure constant dc voltage.
Transfor ....etc

Maximal Subspace Co regulated Gene Clustering - IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING, VOL. 20, NO. 1, – java
Abstract—
Clustering is a popular technique for analyzing microarray data sets, with n genes and m experimental conditions. As explored by biologists, there is a real need to identify coregulated gene clusters, which include both positive and negative regulated gene clusters. The existing pattern-based and tendency-based clustering approaches cannot directly be applied to find such
