A NOVEL METHOD OF COMPRESSING SPEECH WITH HIGHER BANDWIDTH EFFICIENCY
Abstract:
This paper illustrates a novel method of speech compression and transmission. This method saves the transmission bandwidth required for the speech signal by a considerable amount. This scheme exploits the property of low pass nature of the speech signal. Also this method applies equally well for any signal, which is low pass in nature, speech being the more widely used in Real Time Communication, is highlighted here.
As per this method, ....etc

A New Induction Motor V/f Control Method Capable of High-Performance Regulation at Low Speeds
Abstract
A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance drop and slip frequency. The scheme proposed fully compens ....etc

Design of Protection system based on post fault conditions obtained using symmetrical components method.

Modern power systems operate close to their security limits and require highspeed
fault clearing to preserve transient stability, reduce fault damage, minimize
outage duration, and improve power quality. To provide high speed tripping for faults
occurring at any point on a transmission line, there must be some form of accurate
protective relays which operate on the basis of post fault values.
Power ....etc

This method is also called potier method. In the operation of any alternator, the armature resistance drop and armature leakage reactance drop IXL are actually e.m.f. quantities while the armature reaction is basically m.m.f. quantity. In the synchronous impedance all the quantities are treated as e.m.f. quantities as against this in M.M.F. method all are treated as m.m.f. quantities. Hence in both the methods, we are away from reality.
Note : This method is based on the separation of armature leakage reactance and armature reaction effects. ....etc

THEORETICAL STUDY OF HIGHER ORDER NONCLASSICALITY IN INTERMEDIATE STATES



1 Introduction

A state of light is called nonelassieal, if its Glauber Sudarshan P function is negative or more singular than a delta function . In these situations quasi probability distribution P is not accepted as classical probability and thus one can not obtain an analogous classical state. For example, squeezed state and antibunched state are well known nonelassieal states. These two lowest order nonelassieal states have bee ....etc

Abstract
Bidirectional flexure analysis of functionally graded (FG) plate integratedwith piezoelectric fiber reinforced composites (PFRC) is presented in this paper. A higher order shear and normal deformation theory (HOSNT12) is used to analyze such hybrid or smart FG plate subjected to electromechanical loading. The displacement function of the present model is approximated as Taylor s series in the thickness coordinate, while the electro-static potential is approximated as layer wise linear through the thickness of the PFRC layer. ....etc
