Compact Size Design with low side lobes of Fractal Linear Array Antenna

Fawwaz Jinan Jibrael; at Talib Hussein; Dr. Refa

Volume 9, Issue 1 , December 2009, Page 1-12

Abstract
  Abstract: In this paper, the fractal concept is used in the linear array antenna design to obtain multiband operation and reduced size. MATLAB programming language version 7.2 (R2006a) is used to simulate the fractal linear array antenna and their radiation pattern. Fractal Cantor linear array antenna ...  Read More ...

A Lab VIEW Based Data Acquisition System for Radial Temperature Distribution

Ali Farooq Lutfi; Hazem I. Ali; Ahmed Mudher Hassan

Volume 9, Issue 1 , December 2009, Page 13-21

Abstract
  Abstract: Lab VIEW (Laboratory Virtual Instrument Engineering Workbench) is gaining its popularity as a graphical programming language especially for data acquisition and measurement. This is due to the vast array of data acquisition cards and measurement systems which can be supported by LabVIEW as ...  Read More ...

Synchronization Capabilities of Heterodyne Optical Solid-State Laser Receiver Based On OPLL

Ghaida A. AL-Suhail

Volume 9, Issue 1 , December 2009, Page 22-33

Abstract
  Abstract: The coherent optical heterodyne receiver for a solid-state laser based on Optical Phase-Locked-Loop (OPLL) is investigated. The phase shift effect of IF-stage at the output laser frequency is proposed under noise terms conditions: shot noise and the components of laser frequency noise. Integral ...  Read More ...

Janan Ateya Mahdi

Volume 9, Issue 1 , December 2009, Page 34-50

Abstract
  Abstract: In this paper, a 128-bit block cipher B-R encryption algorithm is proposed which is an evolutionary improvement of 64-bits Blowfish designed to meet the requirements of the Advanced Encryption Standard. It is compact, speedy, simple and easy to understand. It is a Feistel network, iterating ...  Read More ...

Implementation of Genetic Algorithm Using FPGA with Applications

Omar Arif Abdul-Rahman; Hanan A. R. Akkar

Volume 9, Issue 1 , December 2009, Page 51-71

Abstract
  Abstract: This paper presents a design of a general purpose GA. It is described using the Very high speed integrated circuits Hardware Description Language (VHDL), which is one of the Hardware Description Languages (HDLs). The complete system is implemented in a single Field Programmable Gate Array ...  Read More ...

Design of a Stochastic Re-Configurable Artificial Neural Networks Using FPGA

Manal; Hannan A. R. Akkar; Mutaz S. Abdul-Wahab

Volume 9, Issue 1 , December 2009, Page 72-94

Abstract
  Abstract: This paper uses the theory of stochastic arithmetic as a solution for the FPGA implementation of a complex feed forward, multi layered neural network. Compared with the traditional digital implementations, the stochastic approach simplifies the computation involved and saves digital resources. ...  Read More ...

Design and Implementation of an Improvement Of Blowfish Encryption Algorithm

Janan A. Mahdi; Saleh M. Al-Qarrawy; Ashwaq T. Hashim

Volume 9, Issue 1 , December 2009, Page 95-109

Abstract
  Abstract: Block cipher is a major part of cipher algorithm like stream cipher and other techniques. Its power comes from dealing with plaintext as parts and operating on each block independently. Blowfish is a secret-key block cipher proposed by B. Shneier. It is a Feistel network, iterating a simple ...  Read More ...

A Modified Bisected-T Matching Network for Microwave Filter Design

Dr. Azad Raheem Kareem

Volume 9, Issue 1 , December 2009, Page 110-115

Abstract
  Abstract : In this paper, a proposed method to implement the image parameter filters is presented. It is based on cascading π-networks and using a proposed bisected-T m-derived matching section to the source and load impedances instead of the use of the cascaded T-networks and the classical bisected-π ...  Read More ...
