لعبة كرة السلة واحدة من الألعاب الجماعية التي تتميز بقوة وسرعة الأداء في المباريات، وهذا لم يأتي مصادفة وإنما جاء نتيجة لتطور العملية التدريبية من جانب ومن جانب آخر امتلاك اللاعبين لقدرات بدنية لها فاعليتها من الأداء ومنها القوة المميزة بالسرعة، إما أهمية البحث فتكمن في السعي إلى تطوير هذه القدرة ومعرفة تأثيرها في الأداء المهاري لتكون عوناً للمدربين في العملية التدريبية. أما مشكلة البحث فيمكن أن توضع في تساؤل هو هل يتم استخدام تمرينات نوعية متنوعة لتطوير القوة المميزة بالسرعة على وفق العتبة اللاهوائية في الأعداد الخاص لمعرفة تأثيرها في تطوير الأداء المهاري. يهدف البحث إلى إعداد تمرينات على وفق العتبة اللاهوائية لتطوير القوة المميزة بالسرعة، ومن ثم معرفة تأثيرها في تطوير الأداء المهاري الدفاعي ( حركة اللاعب المدافع، والسحب الدفاعي). أما فرض البحث فيشير إلى أنّ هناك فروقاً ذات دلالة إحصائية بين الاختبارات القبلية والبعدية في متغيرات البحث. أجري البحث على لاعبي الشباب لنادي الأعظمية الرياضي بعدد (12) لاعب وبنسبة (16.66%)، إذ تم إجراء الاختبارات التالية (القوة المميزة بالسرعة للذراعين والرجلين، حركة اللاعب المدافع، السحب الدفاعي) وأستمر البحث للفترة من (24/8/2013 ولغاية 26/10/2013)، فضلاً عن الوسائل الإحصائية المناسبة. استنتج الباحثون إن التمرينات المستخدمة في البحث على وفق العتبة اللاهوائية أدت إلى تطوير القوة المميزة بالسرعة للذراعين والرجلين ومن ثم أحدثت تطوراً في متغيرات البحث المهارية. يوصي الباحثون بضرورة استخدام التمرينات البدنية اللاهوائية في التدريب كونها فعّالة في تطوير القوة المميزة بالسرعة والتي بدورها لها تأثيرها في تطوير مهارتي (حركة اللاعب المدافع، والسحب الدفاعي)، وذلك من خلال تخصيص الوقت الكافي لها في الوحدات التدريبية.
The research aims at identify the role of the electronic trading system used in the Iraq stock exchange to promote trading activity for the stocks of listed companies in this market.

Show MoreThe paper presents the design of a system consisting of a solar panel with Single Input/Multiple Outputs (DC-DC) Buck Converter by using Simulink dialogue box tools in MATLAB software package for simulation the system. Maximum Power Point Tracking (MPPT) technique depending on Perturb and Observe (P&O) algorithm is used to control the output power of the converter and increase the efficiency of the system. The characteristics of the MSX-60 PV module is chosen in design of the system, whereas the electrical characteristics (P-V, I-V and P-I curves) for the module are achieved, that is affected by the solar radiation and temperature variations. The proposed design module has been found to be stable for any change in atmospheric tempera

The rise of edge-cloud continuum computing is a result of the growing significance of edge computing, which has become a complementary or substitute option for traditional cloud services. The convergence of networking and computers presents a notable challenge due to their distinct historical development. Task scheduling is a major challenge in the context of edge-cloud continuum computing. The selection of the execution location of tasks, is crucial in meeting the quality-of-service (QoS) requirements of applications. An efficient scheduling strategy for distributing workloads among virtual machines in the edge-cloud continuum data center is mandatory to ensure the fulfilment of QoS requirements for both customer and service provider.
