The Regression analysis is considered as a basic element of statistics science elements, and it is an important style of applied statistics when studying different social and economical phenomena. As well as it is considered the most statistical method used in different sciences and fields, and it determines in clear picture the relations among the variables in the form of equation replaced from the degree of parametric on the strength and the importance of this relationship .And ;also it repots the degree of prediction and response ;also ,it is necessary in regression planning and making decisions for finding regression equation .And it is one of modern styles which tak observable caring especially in artificial neural networks. Our main aim is using neural networks in regression in special visage comparison of neural networks styles with classical styles in analyzing linear and non linear regression of prediction in monthly production of electric energy for the seven years i .e from 2006 to 2012 . The research includes the method of analyzing prediction and regression by using the two methods, classic and neural networks and making comparison between the two methods , the 1st method involve the linear model by using the data of chemical operation as a dependent variable 7 reaction time ,temperature as an independent variables for 2 years while the 2nd used the data for seven last years to reach the best method in evaluating statistical parameters , to support the research we generate three types of data one for simple linear regression , 2nd for time series and 3rd for non liner data. The results prove that neural networks are the best method in non linear models while the reverse in the linear models explaining best ways their results.
A school uniform is an international educational phenomenon , and that each
state through its pedagogical educational system imposes uniform hopping for goals
and visions that complement their theoretical framework, because of its extreme
importance that benefits the school administration, parents and pupils . The carried
out researches unanimous in various parts of the world on its importance,
including : the achievement of equality between students and strengthen their
affiliation to the school as well as the good appearance , and reduces competition in
the clothing and the maintenance of order in the classroom and school as well as
increases the seriousness and focus of students to study and make them known bot
Developed the study idea to harvest torrential rains from the plateau of Western style economic cost little help to get the amount of water may exceed 2 billion m 3 per year (depending on the amount of rainfall in that year) has been exploited for agricultural projects or add water to the lakes and rivers. Adopted at the product issued by the oil company, the center (Daura Filtered) reduces the ability of soil to absorb and filter rain water to as much as possible and raise the proportion of surface runoff in addition to this that the product environment-friendly fades and evaporates within 3 years and recognized him in the states was used Successfully.
The presentwork is a theoretical study in the field of charged particle optics. It concentrates on the design of electrostatic enzil lens for focusing charge particles beams, using inverse method in designingthe electrostatic lens. The paraxial ray equation was solved to obtain the trajectory of the particles, the optical properties such as the focal length and spherical and chromatic aberration coefficients were determined. The shape of the electrode of the electrostatic lens were determined by solving poison equation and the results showed low values of spherical and chromatic aberrations, which are considered as good criteria for good design.
There are many teacher and parents suffer from reduce the ability of attention to the children, so the attention not settle on nothing not only to minute for time, so the research aim to following:
1-Is the using the positive reinforcement lunch in take attention of kindergarten visual? 2-1-Is the using the positive reinforcement article in take attention of kindergarten visual? 3-1-Is the using the positive reinforcement symbol in take attention of kindergarten visual? 4-1-Is the using the positive reinforcement action in take attention of kindergarten visual? 5-Is the using the positive reinforcement socialization in take attention of kindergarten visual? 6-what the most percentage obtain of the six factors of take attention?
Change the properties of the river hydrological and geomorphological during his career from its source to its mouth depending on the variables may be quick effect and short-term, addressed the study put the Tigris River geomorphological and hydrological and environmental in the city of Baghdad and found that most of the manifestations geomorphological indicate that the river enters the aging in the area were not so previously evidence suggests hydrological and environmental river that entered this stage long ago may be an extraordinary period. He found that the cross sections and locations of erosion and sedimentation size and type of flow patterns may change with moderate values to patterns with relatively abnormal values for the river.

Show MoreLiterature historians and researchers almost agree that literature is a product of the environment and it is the product of interaction of events and it affected by the direction of that environment and then the literature affects the its environment and the modern science confirms this fact until make the environment competes hereditary factor in its effect because that each environment has its characteristics which affect the literature and leaves its effect on it and even when a writer exaggerate in its monopolize and tyranny of selfin its literature, he cannot be away from affection by including around of literature because the literature is the mirror that reflects aspects of the environment. In other words, literature is expression

This requires that we first identify the concepts of making polices on the one hand, and of COs on the other hand. Initially, polices starts as personal ideas that are, later, turned by some groups of people into suggestions. When the governments adopt these suggestions, they become state policies as shown by the following: Idea ----------> Suggestion--------> Policy. COs are groups of free voluntary organizations acting to bridge the gap between the state and the public, and to respond to the latter's demands. The organizations includes, among others, trade unions and professional associations. In oth

Using this teaching strategy, teachers and students take turns leading discussions regarding sections of text using the four strategies: predicting, questioning, clarifying and summarizing. This study is an attempt to investigate the effect of using reciprocal teaching on improving female college students' achievement in reading comprehension. To fulfill the aim of the study, the researcher has adopted two null hypotheses: first, there is no significant difference between the achievement of students' who practice the reciprocal teaching technique and that of students who do not practice it. Second, there is no statistically significant difference

There are many sources of newspapers for obtaining local news, as these sources are distributed to the newspaper's own sources and external sources.
Self-sources are the newspaper's own sources, through which it is possible to obtain this news, such as the representatives of the newspaper and its correspondents and the journalists working in it. This is the example in this way.
The external sources are distributed to local and international news agencies and sa
Allah created the human from clay and made the system of marriage between male
and female as a reason for life continuity and human staying. This system produced an
organization called (the society) which is defined as a group lived in limited time and place.
Islam put fundamental and conditions of the righteous society in the Holy Quran and
prophetic sunna. Islam also put the solutions for problems (if they got) , naturally, these
problems may happened because of the nature of the life.
The problem of the research is summarized by that the problems of the society
enlarged in our Islamic society more than time ago. In the same time , some solution are
