IMPROVEMENT OF DATA INTEGRITY USING DIFFERENT ENCRYPTION ALGORITHMS

Serwan Waleed Jirjees

Volume 11, Issue 2 , December 2011, Page 1-6

Abstract
  Abstract: Web services send and receive messages over standard Internet protocols such as HTTP. Plaintext messages can be intercepted by an attacker and potentially viewed or even modified for malicious purposes. By using message protection, we can protect sensitive data against threats such as eavesdropping ...  Read More ...

FUZZY-GENETIC CONTROLLER FOR CONGESTION AVOIDANCE IN COMPUTER NETWORKS1

Prof. Dr. Mohammed Z. Al-Faiz; MIEEE; Assistant Lec. Ali M. Mahmood

Volume 11, Issue 2 , December 2011, Page 20-27

Abstract
  Abstract: In this paper a fuzzy proportional-Integral (FPI) controller is designed as an Active Queue Management (AQM) in internet routers to improve the performance of PI controller for congestion avoidance in computer networks. Firstly the parameters of FPI controller are selected by trial and error ...  Read More ...

CONVERSION OF ENGLISH CHARACTERS INTO BRAILLE USING NEURAL NETWORK1

Assistant Prof. Dr. Mohammed Y. Hassan; Ahmed G. Mohammed

Volume 11, Issue 2 , December 2011, Page 28-35

Abstract
  Abstract: The Braille system is a method that is widely used by blind people to read and write. Braille generally consists of cells of raised dots arranged in a grid. The presence or absence of dots can be sensed by the blind people’s fingertips to give them the coding for the symbol. The electronic ...  Read More ...

Dr. Muna H. Saleh; Dr. Mazin Z. Othman; Dr. Arif A. Al-Qassar

Volume 11, Issue 2 , December 2011, Page 36-43

Abstract
  Abstract: Mobile robot is a mechanical device capable of moving in an environment with a certain degree of autonomy. The main goal of this work is to design, and simulate an intelligent controller for autonomous mobile robot named Fuzzy like PD Controller, as the test bed for future development of an ...  Read More ...

MEASUREMENT OF HUMAN LEG JOINT ANGLE THROUGH MOTION BASED ON ELECTROMYGRAPHY (EMG) SIGNAL1

Dr. Yousif I. Al-Mashhadany

Volume 11, Issue 2 , December 2011, Page 44-55

Abstract
  Abstract: Surface electromyography (SEMG) measurement technique for the signal was produced through the contraction of muscles in a human body. The surface electrode is connected on the skin of the muscle. This paper presents an off-line design for the estimation of the actual joint angle of a human ...  Read More ...

  Abstract: A Tuning Model Reference Adaptive Controller (TMRAC) for a synchronous generator is presented in this paper. The controller performs the function of terminal voltage of the machine. The proposed controller is used to overcome the problems of nonlinearities and parametric uncertainties for ...  Read More ...

LOW DENSITY PARITY CHECK (LDPC) CODES FOR A PROPOSED SLANTLET TRANSFORM OFDM SYSTEM IN A RAYLEIGH FADING CHANNELS WITH PERFECT AND PILOT CHANNEL ESTIMATION FOR M_ARY PSK MODULATION1

Lect. Ghanim Abd Al-Kareem

Volume 11, Issue 2 , December 2011, Page 65-78

Abstract
  Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high bit rate data transmission in a multipath fading environment that causes intersymbol interference (ISI). In this paper, two steps are used to improve the error rate performance of OFDM system. First, ...  Read More ...

Proposal of Creating Entity-Relationship Table from English Sentences Groups1

Maitham A. Naji

Volume 11, Issue 2 , December 2011, Page 79-88

Abstract
  Abstract: The aim of this research is to provide a computerized technique to build Entity Relationship Table (ERT) instead of Entity Relationship Diagram(ERD). The ERT contains Source Node Type (SNT) and Destination Node Type (DNT) which are either Entity or Attribute. Also, it contains the source and ...  Read More ...
