Overcoming The Effect Of Jpeg Compression On Steganography, Imad M. Al- Hussaini, Hussain J. Abass, M. Al-Towayjri Jan 2004

Overcoming The Effect Of Jpeg Compression On Steganography, Imad M. Al- Hussaini, Hussain J. Abass, M. Al-Towayjri

Iraqi Journal of Computers, Communications, Control and Systems Engineering

This paper presents an intelligent modeling technique that combines the merits of Fuzzy Logic (FL), Neural Networks (NNs) and Genetic Algorithms (GAs), where the GA is used to train a Fuzzy Neural Identifier (FNI) to identify ill-defined dynamical systems using the series-parallel identification model. The parameters of the FNI (including the input and output scaling factors, the centers and widths of the membership functions (MFs) for the input variables, and the quantization levels of the output variable, that are subjected to constraints on their values by the expert) are modified by the real-coding GA with hybrid selection method and elitism …

Optimal Shunt Capacitor Placement In Power Distribution System Using A Genetic Algorithm, Akram Fajer Bati, Nawfal M. Taher, Hazem Mohammed Jan 2004

Optimal Shunt Capacitor Placement In Power Distribution System Using A Genetic Algorithm, Akram Fajer Bati, Nawfal M. Taher, Hazem Mohammed

Iraqi Journal of Computers, Communications, Control and Systems Engineering

The problem of optimal placement of capacitors determines the size, type (fixed or switched), and locations of the capacitors to be installed in a radial distribution feeder that will reduce power loss while minimizing the costs of investment and installation of the capacitor banks. The present work is devoted to determine the optimal locations and sizes of capacitors in radial distribution system with different load levels using a genetic algorithm, taking in consideration the economic saving and cost of the capacitor. The optimal capacitor placement consists of problem formulations (based on the load flow equations in distribution system), genetic algorithms …

Down Link Beam Forming For Capacity Improvement Of Wireless Indoor Communication Systems, Amin M. Abbosh Jan 2004

Down Link Beam Forming For Capacity Improvement Of Wireless Indoor Communication Systems, Amin M. Abbosh

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this paper, a beam forming method has been used to design sector antennas for the locally centralized radio communication system covering one building floor. Its ability to increase the capacity is investigated. The results show that the capacity can be increased by about (35%) when replacing the omnidirectional antennas by the designed antennas if the Dynamic Channel Allocation (DCA) is used. The increase in the capacity can be as high as (500%) when Fixed Channel Allocation (FCA) is used. This improvement really marks out the problem FCA has with the co-channel interference when using omnidirectional antennas. The results also …

Design, Implementation, And Testing Of A Control System For Heat Treatment Furnaces Crane System Based On A Single Chip Microcontroller, Ameera Ali Salman Jan 2004

Design, Implementation, And Testing Of A Control System For Heat Treatment Furnaces Crane System Based On A Single Chip Microcontroller, Ameera Ali Salman

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Design, implementation, testing, and installation of a control system for a Heat Treatment furnaces crane system are carried out. A simple structure for the control system is defined as to meet the hardware functional requirements of sensing the input variables, commanding actuators. The basic hardware parts of the control system are based on the single chip microcontroller unit and the associated logic circuit. Micro controllers are found in small, minimum-component designs performing control- oriented activities; these designs were often implemented in the past, using dozens or even hundreds of digital ICs. So micro controllers are suited to "control" of I/O …

Teaching Twice Exceptional Children: Gifted With Learning Difficulties: Professional Development And Provision In A Montessori School, Elaine Lewis Jan 2004

Teaching Twice Exceptional Children: Gifted With Learning Difficulties: Professional Development And Provision In A Montessori School, Elaine Lewis

Theses: Doctorates and Masters

This study seeks to investigate the teaching of gifted children in a Montessori school, with particular reference to gifted students with learning difficulties in writing. A review of the literature on the Montessori method of education and on provision for gifted children, shows considerable philosophical and practical overlap in these two fields. However, it appears that this theoretical overlap is not necessarily realised in practice. Furthermore, although considerable research has been conducted on the characteristics, identification and classroom provision for the gifted, very little has been undertaken on the actual provision for gifted children in Montessori schools or gifted children …
