أن لعبة كرة السلة في تقدم وتطور مستمر حالها في ذلك حال الألعاب الرياضية الأخرى حيث أن الفضل في ذلك يعود إلى المعرفة بالعلوم المختلفة وكذلك البحث العلمي من اجل تحقيق نتائج متقدمة تنشدها معظم الدول ومنها العراق على الصعيد المحلي والعربي والدولي. ومما لاشك فيه أن متطلبات تطور مستوى نتائج القدرات البدنية في أيُة لعبة مرتبطة بالبرمجة والتخطيط الصحيح للمناهج التدريبية إذ تقودنا هذه الحقيقة إلى إجراء المزيد من الاختبارات بصورة دورية كونها كما أشار جونتربلوم Günter Blume (أداة لإثارة الدافع والتفوق واستمرار التقدم) ( )، ولكي يتم من خلالها الحصول على معلومات دقيقة يمكن استثمار نتائجها لغرض الحكم والتقويم والتوجيه بشكل منتظم. ويعد علم الاختبارات والقياس إلى جانب علم التدريب الرياضي والعلوم الرياضية الأخرى من الضروريات الأساسية التي يجب أن تؤخذ بنظر الاعتبار عند استخدام الوسائل التي من شأنها الارتقاء بالمستوى إلى ما يرضي الطموح مختصرةً في ذلك الجهود والإمكانيات، وقد برزت أهمية هذا العلم من خلال إمكانية التقويم الموضوعي لكل من النواحي البدنية والمهارية والخططية والوظيفية والنفسية والتربوية كمؤشرات للحالة الراهنة، وما يرتبط بها من واجبات العلم الثاني في تقديم الأساليب والطرائق المعتمدة في مناهج العملية التدريبية والارتقاء بها. أن هذا الترابط في الواجبات يساهم بصورة فاعلة في تهيئة السبل أمام التشخيص والتوجيه والتصنيف ووضع المعايير لرصد الجوانب الإيجابية والمحافظة عليها وتطويرها من ناحية وتلافي الجوانب السلبية من ناحية أخرى. وفي ضوء ما تقدم ومن اجل تحديد وتقويم تلك المعايير برز دور الخبراء والباحثين في وضع مجموعة اختبارات وبطاريات خاصة بكرة السلة متميزة بثقلها العلمي لمعرفة قدرات اللاعبين الحقيقية وصلاحية الأساليب والطرائق المستخدمة في التدريب. وبناءاً على ذلك فإن أهمية البحث تتجلى في تحديد المعايير وبصورة دورية لقدرات اللاعبين من أجل تحقيق الارتقاء بالمستوى التدريبي للمدربين والأداء للاعبين نحو الأحسن، وزيادةً على ذلك النهوض بمستوى لعبة كرة السلة العراقية.
In this paper, we derived an estimator of reliability function for Laplace distribution with two parameters using Bayes method with square error loss function, Jeffery’s formula and conditional probability random variable of observation. The main objective of this study is to find the efficiency of the derived Bayesian estimator compared to the maximum likelihood of this function and moment method using simulation technique by Monte Carlo method under different Laplace distribution parameters and sample sizes. The consequences have shown that Bayes estimator has been more efficient than the maximum likelihood estimator and moment estimator in all samples sizes

An efficient combination of Adomian Decomposition iterative technique coupled Elzaki transformation (ETADM) for solving Telegraph equation and Riccati non-linear differential equation (RNDE) is introduced in a novel way to get an accurate analytical solution. An elegant combination of the Elzaki transform, the series expansion method, and the Adomian polynomial. The suggested method will convert differential equations into iterative algebraic equations, thus reducing processing and analytical work. The technique solves the problem of calculating the Adomian polynomials. The method’s efficiency was investigated using some numerical instances, and the findings demonstrate that it is easier to use than many other numerical procedures. It has

Show MoreIn recent years, the positioning applications of Internet-of-Things (IoT) based systems have grown increasingly popular, and are found to be useful in tracking the daily activities of children, the elderly and vehicle tracking. It can be argued that the data obtained from GPS based systems may contain error, hence taking these factors into account, the proposed method for this study is based on the application of IoT-based positioning and the replacement of using IoT instead of GPS. This cannot, however, be a reason for not using the GPS, and in order to enhance the reliability, a parallel combination of the modern system and traditional methods simultaneously can be applied. Although GPS signals can only be accessed in open spaces, GP

Since the railway transport sector is very important in many countries of the world, we have tried through this research to study the production function of this sector and to indicate the level of productivity under which it operates.
It was found through the estimation and analysis of the production function Kub - Duglas that the railway transport sector in Iraq suffers from a decline in the level of productivity, which was reflected in the deterioration of the level of services provided for the transport of passengers and goods. This led to the loss of the sector of importance in supporting the national economy and the reluctance of most passengers an

Background: Juvenile idiopathic arthritis (JIA) is a chronic disease of childhood. Increased prevalence of periodontal disease and dental caries in juvenile idiopathic arthritis is due to difficulties in executing good oral hygiene. This study was conducted to assess oral health status in patients with Juvenile idiopathic arthritis according to age and duration of illness. Materials and methods: A research was conducted among Juvenile idiopathic arthritis patients attending Baghdad Teaching Hospital with different age and both gender, underwent a clinical evaluation of their dental and oral condition. Diagnosis of dental caries was done according to the criteria of WHO (1997). Dental plaque, gingival condition, calculus were assessed by PI/
