The demand growing of energy is offset by the weakening of the generating capacity of power due to the war conditions in Syria. As the windows are the means of optical communication between inside and outside of the building, the source of the ventilation and the natural lighting, thus having an important effect on the thermal performance of the building, which affects the consumption of energy. so the search relied on proposing alternatives for glass to test its thermal performance, the choice of alternatives was based on the diversity between the values of solar radiation permeability and the visual light in addition to enumeration of the layers, to which end the computer simulation method was adopted and the results were compared to a model Standard (single-transparent). The results of the comparison showed that the amount of energy saving could be as high as 35% for the face of the sun-exposed facades directly. By reducing the permeability of the total glass of solar radiation and increasing the permeability of the visible light to increase the amount of natural illumination, plus the adoption of a Multi-layered glazing system , the study recommended that appropriate glass selection must be taken into account in the early design phase

Research summary
تتناول هذه الدراسة تقييم أداء زجاج النوافذ من منظور استهلاك الطاقة الكهربائية في المباني، وذلك في ظل الظروف الصعبة التي تمر بها سوريا بسبب الحرب والتي أثرت على القدرة التوليدية للطاقة الكهربائية. يركز البحث على أهمية النوافذ كوسيلة اتصال بصري بين داخل المبنى وخارجه، ومصدر للتهوية والإضاءة الطبيعية، وتأثيرها الكبير على الأداء الحراري للمبنى وبالتالي استهلاك الطاقة. يقترح البحث بدائل لأنواع زجاج مختلفة لاختبار أدائها الحراري، معتمدًا على قيم نفاذيتها للإشعاع الشمسي والضوء المرئي، بالإضافة إلى تعدد الطبقات. تم استخدام أسلوب المحاكاة الحاسوبي باستخدام برنامج DesignBuilder لمقارنة النتائج بنموذج قياسي (الزجاج الشفاف). أظهرت النتائج أن استخدام زجاج منخفض النفاذية للإشعاع الشمسي وعالي النفاذية للضوء المرئي يمكن أن يقلل من استهلاك الطاقة بنسبة تصل إلى 35% للواجهات المعرضة للشمس مباشرة. توصي الدراسة بضرورة اختيار الزجاج المناسب في مرحلة التصميم المبكرة لتحقيق كفاءة في استهلاك الطاقة.
Critical review
دراسة نقدية: تقدم هذه الدراسة مقاربة مهمة لتقييم أداء زجاج النوافذ من منظور استهلاك الطاقة الكهربائية، وتسلط الضوء على أهمية اختيار الزجاج المناسب في تحسين الأداء الحراري للمباني. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولية إذا تناولت أيضًا تأثير العوامل البيئية الأخرى مثل التلوث والضوضاء على أداء الزجاج. كما أن الاعتماد الكبير على المحاكاة الحاسوبية قد يكون محدودًا إذا لم يتم التحقق من النتائج من خلال تجارب ميدانية فعلية. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر فعالية إذا تناولت أيضًا تكاليف التنفيذ والصيانة لأنواع الزجاج المختلفة، مما يساعد في تقديم توصيات أكثر شمولية وواقعية للمصممين والمهندسين.

Batteries are energy storage devices that are particularly useful for powering small portable devices like phones, laptops and entertainment devices as well as mobility devices that travel over the earth's surface, through water and air. During the night, or during a period of low solar irradiation, energy is supplied to the load from the battery in solar electrical Power Systems, and that provides Continuity of power supply, and on the other hand boosts the Reliability of the system.
The target of this study is improving the electrical power systems performance estimation because of its importance in complex modern networks investment that have a lot of advanced equipments. Having a complete representation of the electrical sy stem makes diagnosis thing much accurate and reliable which is used in electrical networks operation and maintenance. We focus in this research on implying different conditions and factors which affect operation and we use fuzzy petri nets for that purpose because of its characteristics in handling with incomplete and uncertainty data . we make our simulation on a real diagram of a refinery to compute its truth degree and discuss the results , we match that adding changing factors at operation contribute in improving networks estimation accuracy and support decisionmaking process .
The re-use of return air in central conditioning systems is one of the most important procedures for saving power consumption. However, the requested fresh air of the people existed within the conditioning space imposes determining the number of ti mes to be used. This research aims to link the work of the central conditioning system (heating) of a facility with the number of people existing within this facility by modifying the ratio of mixed fresh air and return air to save the electrical power consumption. Also, to raise the temperature of the mixture air by controlling the flow of hot water continuously rather than using on-off technique. As well as, to respond to any change in the number of people and get rid of repeated machine starting. Our research has been done by using specialized physical model consisted of test room, heat and movement sensors, pump, water tank, heat exchanger and air mixing blades. These devices are controlled by microcontroller type PIC16F877A. The experimentally obtained results showed the ability of controlling the amount of return air depending on the number of people and controlling the speed of the pump continuously providing a saving of electrical energy consumption up to 68% compared with the case of full speed.

Wireless Sensor Networks (WSN) have applications in many different areas of life, such as health care, environmental monitoring, and military and economic areas and in industrial automation and many other applications. The development of these net works and the improvement of their performance occupy an important place of interest in research centers and specialized scientific institutes. The interest in these structures as a way to improve the performance of these networks leads to good results in this area. The cluster structure is one of the most important structures that have received increasing attention over recent years. This research suggested a modification of the structure of the cluster tree WSN dividing clusters into sub-groups, and each group of these sub-groups operates like a tree from a small amount of nodes. The results that have been obtained by means of simulation indicate a significant improvement in terms of reducing energy consumption and thus an increase in the lifetime of the network, as compared to traditional cluster tree WSN. But that was at the expense of slightly lower rates of transmission and delivery ratio in the nodes of these networks. This leads us to recommend using this method to build the networks used to monitor protected agriculture and other networks with low transmission rates.
