Research summary
تقدم هذه الدراسة بحثًا نظريًا حول تحسين أداء نظام ضخ شمسي مستقل عن الشبكة الكهربائية باستخدام مضخة طاردة مركزية غاطسة متغيرة السرعة وألواح شمسية متحركة يتم التحكم بها بواسطة متحكم منطقي مبرمج (PLC). تم تصميم ونمذجة النظام باستخدام برنامج TRNSYS، معتمدين على معلومات الطقس لمنطقة دير الزور. في المرحلة الأولى، تم دراسة تأثير تغير الإشعاع الشمسي على أداء النظام والألواح ثابتة، مع تغير سرعة دوران المضخة. في المرحلة الثانية، تم تحريك الألواح من الشرق إلى الغرب بزاوية 110 درجات باستخدام نظام تحكم، مع تغيير سرعة دوران المضخة لتوافق الاستطاعة الكهربائية المتوفرة من الألواح. أظهرت النتائج أن استخدام منظم يعدل سرعة دوران المضخة وفق الاستطاعة المتوفرة من الألواح يزيد من عدد ساعات عمل المضخة خلال اليوم، مما يحسن إنتاجية الماء بنسبة تصل إلى 33% في الصيف و10% في الشتاء.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين كفاءة أنظمة الضخ الشمسية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل الرياح ودرجة الحرارة على أداء النظام. ثانيًا، يمكن أن تكون التكلفة الأولية المرتفعة لنظام التحكم المتحرك عائقًا أمام تطبيقه على نطاق واسع، ولم يتم مناقشة ذلك بشكل كافٍ. ثالثًا، الاعتماد على بيانات الطقس لمنطقة واحدة قد لا يكون كافيًا لتعميم النتائج على مناطق أخرى ذات ظروف مناخية مختلفة. على الرغم من هذه النقاط، فإن الدراسة تقدم حلولًا عملية لتحسين كفاءة أنظمة الضخ الشمسية وتساهم في تعزيز استخدام الطاقة المتجددة.

Nowadays, wireless networks are spreading more and more. The majority of installed networks have become wireless due to the simplicity of installation; where they do not need an infrastructure. This does not mean that the role of the wired networks i s being eliminated. Instead, the wireless networks are considered as a complementary of the wired networks. With all types of networks from personal and local area networks (PAN and LAN) to wide area networks (WAN) especially the Internet, research has become oriented to focus on the quality of service (QoS) and the integration among all these networks taking into account the Internet which is considered as the backbone for each network that wants to exchange the information with any other network all over the world. In our research, we take into account the quality of service in the broadband networks such as the WiMax network (Worldwide Interoperability for Microwave Access) with IEEE 802.16e standard which covers cities and supports the mobility. This network can be used to interconnect the rural zones with the center of cities, this kind is called point-to-point, or it can be used to cover the cities and is called point-tomultipoint, The last one is used to interconnect different wireless networks especially the local one which has infrastructure (Wi-fi: Wireless Fidelity) and networks which have many users and called hotspots. However, the cells of Wi Max in the cities are called hotzones. We propose a system model that performs the load balancing process between the base stations of WiMax network. This means, the proposed load balancing algorithm exchanges the terminals between the adjacent base stations in order to make the throughput in each base station equals to the throughput in the others. This will improve the performance of the overall network and increase the available bandwidth for each terminal; in addition, this will increase the number of terminals which can be served. On one side, these advantages return to the subscribers, they also return to the operator on the other side, not to mention the good renown that the operator will get from subscribers that will make more subscribers join to this network. The proposed load balancing system can be centralized; implemented in a centralized server connected to all base stations or distributed system implemented in each base station. The load balancing algorithm which consists of several steps is placed in a controller that achieves it. The load balancing process and the handover procedure have to be fast enough in order to prevent the adverse effect on the quality of service especially for the real-time applications users.

Adopted Find descriptive approach, and included the research community beneficiaries of the container port of Latakia agents offshore and sincerely customs agents terminal services, totaling (68) are working effectively, where BI views using the comprehensive inventory, has been restored (65) complete and valid for statistical analysis form.
This research aims to check the actual performance of the work of the propeller depending on series of results issued from Hamburg basins that are known by RANSE where the arcs analysis and the hydrodynamic characteristics of the propeller work in open water are done by using the commercial program CFD Analysis m by Hydro Comp. Thus, the results were compared with the experimental data and the study of fluently around the different parts of the ship and the definition of resistance values and friction factor CF. These values were compared with those issued by ITTC basins and coincidence was found between those of RANSE and the experimental values in the different stages of study. Therefore, a collection of solutions related to the work of propeller were achieved in addition to the evaluation of the level of interaction and the exchanged effect of the propeller work in different conditions, and the definition of degree of difference resulted from the values of the rotation moment and the factors of advance and control the are resulted from the use of CFD program. The numerical results and the syntheses data were discussed in case of working in open water.
This Research suggests a new mechanism that aims to increase the effectiveness of surveillance systems by extracting the moving objects coming from surveillance camera in order to identify them and propose a new mechanism for indexing and storing i n database and classified them according to the basic characteristics and strong indicators and retrieval when needed in less possible time. The basic idea lies in the combination of the basic characteristics of the goal (color, edges and texture) which ensures the best performance in extracting the basic target features and depend on it as indexes, then nonlinear transfers has been done on the edges of the target in order to get a picture bearing the minutest details, then conducted adverse transfers on the edges of the target during the process retrieved from the database. Finally, we propose a new mechanism for indexing all images tabase to Retrieval them in best accuracy and less time, and a program had been achieved to realize this idea.
This study aimed to answer the following main question: What is the role of kindergarten principals as resident supervisors in improving the performance of parameters from the parameters point of view? In order to achieve the objectives of the st udy, the researcher followed the descriptive approach, and designed a questionnaire consisting of (64) paragraphs divided into four areas: Planning, implementation of teaching, classroom management, evaluation.) The questionnaire was distributed to kindergarten teachers in Homs, (Government and private).
