Abstract: A data compression scheme suggested by Ziv and Lempel, LZ77, is applied to text compression. A slightly modified version suggested by Storer and Szymanski ,LZSS, is found to achieve compression ratios as good as most existing schemes for a wide range of texts. In these two methods and all other dynamic methods, a text file is searched from left to right to find the longest match between the lookahead buffer (the previously encoded text) and the characters to be encoded. The method suggested in this work depends the searching in two directions, from left to right and from right to left, although this process takes more time, better compression results were obtained

Abstract: Regression models are regarded as the most important ones used in statistical models in defining the relation among variables through the available data which can be applied to various sciences . In most of these applications , there is a dependent variable and independent variables and the linear relation between them represents multiple linear regression function . The values of the dependent variable can be predicted when the independent variables take definite values and the model's parameters are estimated through minimizing deviation of squares among the values of the real and estimated data. In this research we use the genetic algorithm to find the minimum sum of error squares, where they are applied to different data in many applications . The genetic algorithm is able to achieve the minimum sum of error squares and estimating the parameters of the model.

Abstract: This paper investigates the field of Video image analysis depending on texture for detecting a goal and tracing its movement in a video series. Analysing images depending on texture is better than depending on colour or shape , for the goal sometimes depends on different features . The aim of this study is to propose a method for tracing a goal within a video series after detecting it in each video frame. This study exhibits one of the techniques of extracting the image features depending on the signal frequency through using Gabor filter and in different trends for each frame. Then the histogram is taken for each frame and the frame given the best description for the goal is selected , in which case the threshold is depended . Then it is transformed into the binary form of the video frame ,to decrease time consumed short in detecting the object target . The algorithm is applied to part of the video frame . The location of the object target is determined through calculating the centre for part of the frame and the operation is applied to the series of the frames of the video film . Two films have been adopted as a research sample ,The first is a person„s movement by the traffic lights in al-Nabi Yunus area and the other are the students movement at the university of Mosul in the College of Education.
