THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex ....etc

ABSTRACT

In this paper a new single phase to three-phase converter for ac motor is proposed. The proposed converter employs only six switches and incorporates active input current haping feature, which results in sinusoidal input current at close to unity power factor. The front-end rectifier in the proposed converter permits bidirectional power flow and therefore provides for excellent regulation against fluctuations in source voltage. This feature also facilitates regenerative braking of ac motor drive. An easy to implement control stra ....etc

Abstruct-
Analysis, design, and implementation of the space vector modulated three-phase to three-phase matrix converter with input power factor correction are presented. The majority of published research results on the matrix converter control is given an overview, and the one, which employs sheous output-voltage and input-current space vector modulation, is systematically reviewed. The modulation algorithm is theoretically derived from the desired average transfer functions, using the indirect transfer function approach. ....etc

Abstract
The ear is a promising candidate for biometric identification. However, in prior work, the pre-processing of ear images has had manual steps, and algorithms have not neces- sarily handled problems caused by hair and earrings. This seminar present a complete system for ear biometrics, including automated segmentation of the ear in a profile view image and 3D shape matching for recog- nition. and evaluated this system with the largest experimental study to date in ear biometrics, achieving a rank-one recognition rate of 97.6%.for ear ....etc

Securable Network in three-party Protocols

Abstract

This work presents quantum key distribution protocols (QKDPs) to safeguard security in large networks, ushering in new directions in classical cryptography and quantum cryptography. Two mediator protocols, one with implicit user authentication and the other with explicit mutual authentication, are proposed to demonstrate the merits of the new combination, which include the following: 1) security against such attacks as man-in-the-middle, eavesdropping and replay, 2) ....etc

1. INTRODUCTION

There is a saying in real estate; when land get expensive, multi-storied buildings are the alternative solution. We have a similar situation in the chip industry. For the past thirty years, chip designers have considered whether building integrated circuits multiple layers might create cheaper, more powerful chips.

Performance of deep-sub micrometer very large scale integrated (VLSI) circuits is being increasingly dominated by the interconnects due to increasing wire pitch and increasing die size. A ....etc

Three Party Authentications for key Distributed Protocol using Implicit and Explicit Quantum Cryptography
Abstract:
The combination of 3AQKDP (implicit) and 3AQKDPMA (explicit) quantum cryptography is used to provide authenticated secure communication between sender and receiver.
In quantum cryptography, quantum key distribution protocols (QKDPs) employ quantum mechanisms to distribute session keys and public discussions to check for eavesdroppers and verify the correctness of a session key. However, public discussions ....etc
