المقدمة Introduction شهد العالم في العقود الأخيرة تطورًا مذهلًا في تقنيات الثورة الرقمية، وفي مقدمتها الذكاء الاصطناعي، الذي يُعد اليوم أحد أكثر مظاهر الكيانات الرقمية تقدمًا وإثارة للجدل. فقد تجاوز الذكاء الاصطناعي كونه أداة برمجية تُستخدم لإتمام مهام بسيطة، وأضحى فاعلًا رقميًا له تأثير حاسم في مجالات متعددة، كالصحة، والصناعة، والتعليم، والعدالة، والأمن، والعلاقات الاجتماعية، وغيرها. وقد بات من المألوف الحد

مارس العراقيون القدماء في حضارة ما بين النهرين الوانا من الانشطة الرياضية والتدريبات البدنية لتطوير لياقتهم البدنية حتى اصبحت تلك الممارسات جزءا من حياتهم ورافقت احتفالاتهم الدينية والاجتماعية والعسكرية، وكان للموسيقى حضور في العديد من المشاهد الرياضية كما كان استحضار العازفين والاتهم الموسيقية مع الجيوش دلالة على دورها الكبير في المشهد العسكري، لذا جاء هدفا البحث في تسليط الضوء على الادلة والشواهد الاث

المستخلص يتضمن البحث شرح موجز لمفهوم نظم المعلومات الجغرافية وعلاقتها مع علم الاثار والتاكيد على اهميتها في هذا المجال وكيفية الاستفادة من هذه النظم في مجال التنقيب عن الاثار مع الاستعانة بالعمل الحقلي المنجز في موقع تنقيبات جامعة الموصل عند تل قوينجق لتوضيح كيفية الاستفادة من مجموعة من مصادر وبرامج نظم المعلومات الجغرافية لسد بعض متطلبات عملية التنقيب عند تل قوينجق في مدينة نينوى الاثرية لعام 2011.

The fractional free volume (Fh) in polystyrene (PS) as a function of neutron -irradiation dose has been measured, using positron annihilation lifetime (PAL) method. The results show that Fh values decreased with increasing n-irradiation dose up to a total dose of 501.03× 10-2 Gy.
A percentage reduction of 2.14 in Fh values is noticed after the initial n-dose corresponding to a percentage reduction in the free volume equal to 42.14/Gy.
The total n-dose induces a percentage reduction of 7.26, corresponding to a percentage reduction of 1.45/Gy. These results indicate that cross -linking is the predominant process induced by n-irradiation.
The results suggest that n-irradiation induces structure changes in PS, causing cross-linking

This study aims to identify the degree of Arabic language teachers at the secondary stage possessing the teaching competencies necessary to develop the skills of literary savor among their students from the perception of educational leaders in Bisha Province. To achieve the objectives of the study, the descriptive approach was used by adopting a comprehensive survey method. The study sample consisted of (48) school principals and Arabic language supervisors in Bisha Province who supervise the teaching of Arabic language at the secondary level in Bisha Province. The necessary data was collected using a questionnaire. The results of the study revealed that the evaluation of the study sample for the degree to which Arabic language teachers

Abstract\

In this research, estimated the reliability of water system network in Baghdad was done. to assess its performance during a specific period. a fault tree through static and dynamic gates was belt and these gates represent logical relationships between the main events in the network and analyzed using dynamic Bayesian networks . As it has been applied Dynamic Bayesian networks estimate reliability by translating dynamic fault tree to Dynamic Bayesian networks and reliability of the system appreciated. As was the potential for the expense of each phase of the network for each gate . Because there are two parts to the Dynamic Bayesian networks and two part of gate (AND), which includes the three basic units of the

This research deals with a shrinking method concerned with the principal components similar to that one which used in the multiple regression “Least Absolute Shrinkage and Selection: LASS”. The goal here is to make an uncorrelated linear combinations from only a subset of explanatory variables that may have a multicollinearity problem instead taking the whole number say, (K) of them. This shrinkage will force some coefficients to equal zero, after making some restriction on them by some "tuning parameter" say, (t) which balances the bias and variance amount from side, and doesn't exceed the acceptable percent explained variance of these components. This had been shown by MSE criterion in the regression case and the percent explained

This research investigates modern linguistics in terms of the “universality” concept, through which linguistics shifted its attention from the description of the phenomenon into finding an interpretation of it. Then it investigates what needs interpretation in the language

The purpose of the current work was to evaluate the effect of Radiation of Gamma on the superconducting characteristics of the compound PbBr2Ca1.9Sb0.1Cu3O8+δ utilizing a 137Cs source at doses of 10, 15, and 20MRad. Solid state reaction technology was used to prepare the samples. Before and after irradiation, X-ray diffraction (XRD) and superconductor properties were examined. Results indicated that the tetragonal structure of our chemical corresponds to the Pb-1223 phase with an increase in the ratio c/a as a result of gamma irradiation. (Tc (onset) ) and on set temperature Tc (offset)) were also dropping from 113 to the 85.6 K and 129.5 to 97 K, respectively, for a transition temperatu
