المستخلص: Weibull failure model considered being one of the well known failure models because of its different applications in addition to its importance in the reliability field and life tests.This thesis focused on a comparison of standard Bayes estimators for reliability function of the two parameters Weibull distribution by usingsix different loss functions, three of them have been suggested by the researcher.And for that, the methodology of this thesis depended on the following methodologies : - First : - Theoretical study, the standard Bayesian estimations has been derivatives elaborately to reach the Bayes estimators forms for the reliability function of Weibull distribution by using symmetric and asymmetric loss functions which been explained elaborately, and these are quadratic loss function, logarithm loss function and precautionary loss function to reach to the standard Bayes estimators which called quadratic Bayes estimator (QB), logarithmic Bayes estimator (LB) and precautionary Bayes estimator (PB)) respectively. And those loss functions have been Modified by suggested three modified loss functions counterpart to the functions above to reach proposed estimators which called (modified quadratic Bayes estimator (MQB), modified logarithmic Bayes estimator (MLB) and modified precautionary Bayes estimator (MPB)) respectively.Second : - Experimental study by designing number of simulation experiments using various values of parameters and sample sizes, and with repetition of (10000) times for the comparison among the estimators and by using the mean square error (MSE) to reach efficient estimators with minimum variance. And a collection of real negative and positive values have been tried for the constant which is used in proposed loss functions to reach the best value may used in the comparison, and then a comparison between the six preference estimators is done to show which estimator is the most accurate to be used for estimation the reliability function of Weibull failure model, and best results have been obtained from those simulation experiments.The results of these experiments showed that the modified precautionary Bayes estimator (MPB) is the best for the reliability function of Weibull failure model than the other estimators which have been used in this thesis, and the second best method is the modified logarithmic Bayes estimator (MLB), and after that the precautionary Bayes estimator (PB) and then the modified quadratic Bayes estimator (MQB), also all proposed estimators are better than the logarithmic Bayesestimator (LB) and the quadratic Bayes estimator (QB) which results not to be shown in preferences.Also the results of these experiments show that every proposed estimator is better than its known counterpart.Third : - Application study by taking the best Bayesian estimator in the simulation experiments which is the proposed modified precautionary Bayes estimator (MPB) and applied practically on two experimental real data from WeatherFord company for oil well digging in the Bazergan area of Misan governorate which are represented by the time to failure of the operation of the drilling fluid pumps.From all above, the most important conclusions and recommendations have been offered from the results of this thesis as a specific contribution in the reliability field.

المستخلص: تعتبر دراسة الفقر وتحليل مؤشراته ومحدداته، من القضايا المهمة بالنسبة للعراق الذي يهدف الى تحقيق التنمية الاقتصادية والاجتماعية بصورة اكثر واقعية.لذلك اختار الباحث هذا البحث وبالاستعانة ببيانات المسح الاجتماعي والاقتصادي للاسرة في العراق الذي نفذ خلال الس | The present study deals with the most important issue which is of critical significance in Iraq - poverty - and its analysis, indications and determines since it tries to achieve the social and economic growth and development in a realistic way. The researcher selects this subject by depending on the social and economic data survey of the household in Iraq which is carried out in 2007 by the central organization of statistics and its subsequent building poverty line based on these data by using (spss) to arrive at the social and economic variables of direct impact on the poverty level. The indications of poverty in Iraq show that the poverty rate comes to 23% and this rate is centered in the rural increasingly than the urban since the poverty rate comes 39% and 16% respectively these indications also show that the size of poor household comes to 9.5 person and for other households 6.3 persons. The illiteracy ratio comes to (25 - 15) years among the poor - 27.1 %. The ratio of those primary school leavers or school - Not Joiners comes to 25 - 2% while other than poor households comes to 11 - 6% As for intermediate school poor - Joiners, the ratio comes to 79.5 % - the results show that 24% of those poor drink undrinkable water. The unemployment ratio for those adults whose age ranging from 15 and more 15% The Results also show that the Average of individuals, monthly Salary for those poor comes to 87 thousand Iraqi dinar while other's Salaries come to 149 thousand Iraqi dinars. The major differences between the a group of poor people and a group of Non - Poor people on the one hand, and on the other hand the main differences between poor people and non - poor people in cities and country sides for more than 20 variables by (T Test). The researcher comes to the fact that there are nine variable of different meaning - which are as follows : the Average of Household size, the ratio illiteracy, the ratio of non - advantage of health care during the period of pregnancy, the ratio of bachelorhood, the ratio of non - having drinkable water, the Average of individual's monthly salary, the Average of individual's monthly expenditure, the ratio of unemployment, Loans ratio to meet the needs of consuming families. The researcher uses the factor analysis to analyze the relationship among the nine Variables to come to the main factors that affect the level of poverty. The researcher also uses the cluster analysis and transferring the nine Variable data into the standard formula to eliminate the difference of measuring units of these Variables and consequently ensuring the Validity of carrying out the process of classifying the data and determining the relationship among factors in terms of similarity and differences and then going in to the clustering method and analyzation together with the way of comparison by means of Box plot which shows the symmetry of data inside the Variable

المستخلص: تحاول الدراسة الحالية بحث وضع الطفولة في العراق واثر الاوضاع السياسية عليه.فلقد تم دراسة وضع الطفل تحت سن الخامسة باعتبارها الفئة العمرية الاساسية للطفل لفهم واقع الطفولة في العراق ولبناء توجيهات علمية تسلط الضوء على المشاكل العديدة التي تواجه الاطفال بغي | This study attempts to study the status of the childhood in Iraq and the impact of the political situations on it.It tries to study the status of the children under the age of five years for it is the essential age of the child to understand the reality of the childhood in Iraq and to build the scientific guidelines that highlight many problems facing the children in order to have the documented procedure to improve their living conditions. The present study focuses on four fundamental axes.The nutrition axis, health axis, Educational axis, and the social axis. The study has calculated the indicators of these four axes relying on real data of a sample whose size is (18144) families obtained from the Ministry of planning and Development Cooperation/Central Bureau of statistics and Information Technology Data.The Data has been analyzed by the statistical program (SPSS VERSION 12.0) using two methods of statistical tools the field of analyzing data of multilateral variables (Multilateral Analysis) namely, cluster analysis and factor analysis.In the light of the results of the data analysis some conclusions are worth observing : 1. The conclusions showed that 840 of the Iraqi children whose age is under five years suffer from the medium or server weight, and that fifth of the children undergo from being pygmy (their length does not suit their age).2. The conclusions also showed that the majority of death cases of the children under five years 85% occur in infants only.3. 3% of the age (36 - 59 months) joins the education like nursing or kindergarten.4. There are differences among provinces in Iraq with regards to the proportion of orphans among children. The higher average is found in AL - Muthana province 9%, in kerbala 9% and in Diyala 8%. This proportion is a result of the unstable circumstances in these provinces which has been shown by the cluster analysis of this indicator.5. The results of the factor analysis showed that the variables (health effects) have a great effect (impact) on forming the first factor on Iraq in general and on the countryside environments, whereas the nutrition variable have a great impact on forming the first factor on urban environment.

المستخلص: ان الخاصية الاساسية لتمييز البيانات المكانية عن بيانات السلاسل الزمنية هي الترتيب المكاني للمشاهدات , وعينات البيانات المكانية تمثل مشاهدات ترتبط بنقاط او مواقع وتتميز هذه البيانات بان ارتباطها يضعف كلما بعدت المسافة وكذلك تتميز بتدرج المكان (( المناطقية | The main property to differentiate the spatial data from time series data is the spatial arrangement of observations and the samples of spatial data represent observations related to points or locations these data are distinguished with the weakness of their connection each time the distance getting far away and the place graduation (location)on the spatial relations of observations are represented in matrix named spatial weights matrix. The spatial econometrics is used in following up the spatial effects like the spatial dependence of observations in different points of place, and spatial heterogeneity arising from relations or parameters model that change with sample data in each time we move within the place , those two points have been neglected in traditional econometrics because of their sinconsistency of statistical assumptions and when taking those spatial effects into consideration ,the statistical influence will be of high efficiency. On the contrary, ignoring these effects will lead to loss the information and will not be as efficient as the dependant sample.Because of the difficulty of deriving the posterior function (on which the Bayesian inference depends) up on applying the Bayesian methods especially in cases that the number of probable models is very large as computing the posterior functions for all these samples requires integration for large dimensions functions which is very difficult Mathematically or inapplicable that requires proper methods can deal with such cases like Gibbs and Metropolis - Hastings sampling by analyzing the posterior distribution to number of conditional distributions for each parameter in the model and then the simplicity of inference for each parameter in the model.The matrix of spatial weights is built by registering the contiguity relations for each location with others in a matrix row (w?) and given (1) if there is a relation between two locations (wij=1) and zero, if it doesn’t (wij=0)as i and j refer to the rows and columns in sequence. For making the summation of each row in the matrix w? equal to 1 , the elements of matrix will be calculated according to the proportion : wij/ ?wij and i=1,2…,n j=1 Consequently, we will get the adjusted matrix W.The practical side was focused on the counting of spatial autoregressive model parameters, and these parameters is the vector ? and it is an ordinary regression parameters vector, and error variance parameter (?2) , and the most important of them is a countig of the parameter (?) which is represent spatial dependance parameter.In order to show the role of the spatial, the practical side included taking the real population for childrens between(1 - 19) year, that had iron deficiency anemia (due to from iron deficiency) that admitted to children’s hospitals in Kurkh district of Baghdad (which had been divided into five geographic regions) for 2010. We have suggested that computing the elements in the adjusted matrix to be on basis of the actual length proportion of the joint borders among different locations that lead to get the accurate estimated value of spatial dependence parameter، where value result of spatial dependence parameter (?) was (0.43) when use Metropolis - Hastings sampling method while value of this parameter when use spatial outoregressive function and by using the adjusted matrix was( 0.57) and value of this parameter when use the same regression function but by using the suggested matrix was (0.85).

It also assumes that the relationship between price and quantity is linear : Quantity is inversely proportional to the price. the researcher has developed a proposed model for the expansion of the model to include all the policies used by oligopoly companies such as advertising and others.The model of von Staklberg is applied when there is a market leader and the rest of the companies are subsidiaries It takes the same relationship between price and quantity in the theory of Cournot that is the second company determines. the quantity that it wants to produce which will be restricted to the first company. This will be the first company the leader, and the second company to be its subsidiary. The researcher also to included all the policies used by oligopoly companies after linking the model to theories of econometrics.The Bertrand model depends mainly on determining the prices not quantities, as in the models of Cournot and von Staklberg. It is supposed that the price of competing companies in some way affects the price of a single company. The researcher also included all the policies used by oligopoly companies after the model was based on the price, quantity and sale price of the competing company only by linking the model to theories of econometrics
