Purification characterization of a catalase from a halotolerant bacterium (Micrococcus sp.)

Some of the enzymes of the wild type Micrococcus sp. strain Gl were detected & it was found that strain Gl was positive for catalase <§c nitratase, then depending on a comparison of intracellular activities for each of catalase & protease enzyme in different NaCl concentrations (2, 10 & 20 %), catalase was choosed for the present study according to its importance & its highest production in all NaCl concentrations. However maximal function of catalase obtained from cells grown in 10 % NaCl as compared with catalase produced from 2 % & 20% NaCl grown cells.

Face recognition system based on radial basis function neural network

Abstract : The global development of security system around the world made the field of recognition most needed, and led the idea of recognition grew up in researchers work; many specifications were found in mankind to differentiate between one and another. However, some of them were old like finger print and other types were modern as iris print, face, sound, palm print and DNA print. This thesis proposed a face recognition system. It is based mainly on classifier unit, which had been chosen as Radial Basis Function Neural Network (RBFN).

Power line data transmission using an OFDM system

Abstract : Ubiquitous high-speed communication is desirable, may be even essential for acceptable quality of life, productivity of business and so on. According to this demand, Power-Line Communication (PLC) arises in this field as a feasible broadband connection. The backbone of this system is of course the PLC modem which its design is a challenging task, as it covers several layers of the Open System Interconnection (OSI) standard.

The morphology of the zygapophyseal joint in relation to biomechanical properties

Abstract : Zygapophyseal joints (or facet joints), are a plane synovial joint which located between the articular facet processes of the vertebral arch. These joints are considered freely movable; the degree of possible motion varies according to the individual structural design and facet planes. Ten dried vertebrae were used for each cervical, thoracic and lumbar regions (220 vertebrae). AutoCAD program finds measurement for the surface area, the curvature, and the angle of the facet processes in each region for the vertebral column.

Development of high performance PC clusters computing system for engineering applications

Abstract : Supercomputing technologies have been limited to the powerful first world nations for a very long time due to the extremely high costs involved in setting-up and maintaining supercomputers. Recently, the availability of high speed networks and increasingly powerful commodity microprocessors is making the usage of clusters, or network of computers as an attractive field for cost effective parallel computing.
