In this paper, the maximum likelihood estimator and the Bayes estimator of the reliability function for negative exponential distribution has been derived, then a Monte –Carlo simulation technique was employed to compare the performance of such estimators. The integral mean square error (IMSE) was used as a criterion for this comparison. The simulation results displayed that the Bayes estimator performed better than the maximum likelihood estimator for different samples sizes.

... Show MoreThe study aims at analyzing the inconsistent structural and semantic aspects found in the plays of N.A Ostrovsky. The analysis, that includes all the linguistics schools of thoughts in modern Russian language, is performed chronologically to clarify all the ambiguities that the Russian language learners may face. Such difficulties lie in the use of inconsistent aspects with complete declarative sentences and adverbial clauses. Hence, it constructs a new sentence category that consists of secondary clause and its syncretism semantic.
The study illustrates the wide scope of both studying the sentence inconsistent

This study aimed at identifying the extent to which the social worker used the techniques of group discussion in the professional practice with the groups of school activity in the schools of Tubas governorate in light of some variables (gender, years of experience, academic qualification). The analytical descriptive method was used due to its suitability for the objectives of the study. A questionnaire was designed to collect data that included (30) items, distributed in three areas .The validity and reliability of the tool were verified and then distributed to the study sample.
The results of the study showed that the highest averages were in the discussion stage domain, where the pre-discussion stage was m

Show MoreThe destruction and protection of cultural property has been a feature of armed conflicts for thousands of years and it has received increasing international focus over the past two decades. This feature was clearly appeared during the recent armed conflict in Iraq. During the conflict, cultural property was subjected to intentional and organised destruction by members of ISIS. Although there are international legal norms to protect cultural property during armed conflict, however, this destruction has proven the failure of those rules to effectively deter these criminal acts. This Article analyses the framework of international law relevant to the protection of cultural property during of armed conflict in the light of that destruction,

Objective: to evaluate effectiveness of normal saline irrigation and povidone iodine soaking in decreasing the number of bacteria.
Patient and method: This was a prospective study of 100 patients who were admitted to Al Kadhimyia Teaching Hospital during the period from May 2012 and April 2013 with diagnosis of acute appendicitis. After appendicectomy was done, patients were randomized into two groups, fifty patients (group one) the subcutaneous tissue was irrigated by

The technology of reducing dimensions and choosing variables are very important topics in statistical analysis to multivariate. When two or more of the predictor variables are linked in the complete or incomplete regression relationships, a problem of multicollinearity are occurred which consist of the breach of one basic assumptions of the ordinary least squares method with incorrect estimates results.
There are several methods proposed to address this problem, including the partial least squares (PLS), used to reduce dimensional regression analysis. By using linear transformations that convert a set of variables associated with a high link to a set of new independent variables and unr
