Abstract
Due to increasing demand for speech communications, efficient techniques in low-rate speech coding are of interest.Here a new compression technique using root cepstral analysis has been proposed. Implementing the proposed method causes the coder to deal with root cepstrum coefficients instead of speech samples. The main idea in using root cepstrum analysis is that some of the trivial coefficients can be ignored to send toward the decoder. Thus considerable reduction in the total bit-rate is achieved. Moreover it has the advanta ....etc

This paper deals with the methods to find out the margin to restore power system solvability (i.e. how much active and reactive power needs to be reduced so that an unsolvable power system can be brought to a stable operating point). The direction in which we reduce the power is important and is considered in the first method of approaching the closest bifurcation point. In the second method, a minimization technique is adopted to find the active and reactive powers at the buses in the power system if the power system had been operated very clo ....etc

MIMO Wireless Channels: Capacity and Performance Prediction


Multiple-input multiple-output (MIMO) communication techniques make use of multi-element antenna arrays at both the TX and the RX side of a radio page link and have been shown theoretically to drastically improve the capacity over more traditional single-input multiple output (SIMO) systems . SIMO channels in wireless networks can provide diversity gain, array gain, and interference canceling gain among other benets. In addition to these same advantages, MIMO links can ....etc

USING THE CONCEPTUAL COHESION OF CLASSES FOR FAULT PREDICTION IN OBJECT ORIENTED SYSTEMS

Abstract: High cohesion is desirable property in software systems to achieve reusability and maintainability. In this project we are measures for cohesion in Object-Oriented (OO) software reflect particular interpretations of cohesion and capture different aspects of it. In existing approaches the cohesion is calculate from the structural information for example method attributes and references. In conceptual cohesion of classes, i.e. in our project we a ....etc

Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ....etc
