Abstract: The databases technology has acquired a great deal of attention from the academic community and computer industry for their wide use and success; it can be described as the most developed growing field in computer or information system. Distributed database helps eliminating many of the shortcomings of centralized database This work concerns with the design and implementation of mark system in the college of engineering of Nahrain University.

Abstract: The extraction of roads from aerial and satellite images is an important task within cartography and planning of new road networks. The recent developments of the Geographic Information System (GIS) require rapid updates of roads all over the planet. Over the past few decades, many automatic and semi-automatic methods were developed for the purpose of road extractions which vary in planning, techniques and application from one to another. The objective of this thesis is to develop and implement a road extraction system.

Abstract: In recent years, the scale of power systems has been expanding and with that expansion stable power supply and smooth power system operation is becoming increasingly important. One measure for increasing stability is to improve the main circuits by raising the voltage or employing series capacitors in power transmission lines, but the generator exciter control method, which makes use of AVR (automatic voltage regulator), is attracting attention because of its inherent cost advantage.
