This research aims to develop the control process of manned railway level crossings depending on the modern control systems that contain microcontrollers, microprocessors, sensors, actuators, communications and software to compose smart automated systems that could be remotely monitored. The control logarithm and flow charts for all the functions that occur on the railway level crossing were used, depending on European standards (Safer European Level Crossing Appraisal and Technology, SELCAT) that aim to develop safety technologies on European railway level crossings. We designed a program to emulate all warnings and procedures that happen on the real railway level crossing, depending on the graphical Programming language (Laboratory Virtual Instrumentation Engineering Workbench, LabVIEW) that insures local monitoring on the crossing, and remote monitoring at the station and on the train via data network. By using the automated method, we were able to determine the approaching train to the crossing precisely, and insuring the provision of all warnings to road users and train driver to increase safety and reduce collision accidents between automobiles and train.

Research summary
يهدف هذا البحث إلى تطوير آلية التحكم بالمعابر السطحية في الخطوط الحديدية السورية التي تدار يدوياً، وذلك بالاعتماد على أنظمة التحكم الحديثة التي تتضمن المتحكمات والمعالجات الصغرية وأجهزة التحسس والمشغلات والاتصالات والبرمجيات لتشكيل نظم مؤتمتة ذكية يمكن مراقبتها عن بعد. تم وضع خوارزمية التحكم والمخططات الصندوقية لكافة الوظائف عند المعبر السطحي بالاعتماد على المعايير الأوروبية (Safer European Level Crossing Appraisal and Technology, SELCAT) التي تُعنى بتطوير تقنيات الأمان في المعابر السطحية الأوروبية. تم تصميم برنامج يحاكي جميع الإجراءات والتحذيرات الموجودة عند المعبر السطحي الحقيقي باستخدام لغة البرمجة الرسومية (LabVIEW) مع إمكانية المراقبة عن بعد عبر شبكة تراسل المعطيات من قبل سائق القطار أو المحطة. يساعد النظام المؤتمت في تحديد اقتراب القطار من المعبر بدقة أكبر، وتأمين كافة التنبيهات والحماية اللازمة لمستخدمي الطريق وسائق القطار، وبالتالي زيادة الأمان وتقليل حوادث التصادم بين السيارات والقطار. تشمل الدراسة تصميم دارة تحكم بالمعبر السطحي باستخدام المتحكمات الصغرية، وتوفير مراقبة الإجراءات الحاصلة عند المعبر السطحي عبر الشبكة باستخدام برنامج LabVIEW، مما يتيح المراقبة والتحكم عن بعد.
Critical review
دراسة نقدية: يعتبر هذا البحث خطوة مهمة نحو تحسين الأمان في المعابر السطحية للخطوط الحديدية السورية من خلال استخدام أنظمة التحكم الحديثة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى التحديات المحتملة التي قد تواجه تطبيق هذه الأنظمة في البيئة السورية، مثل التحديات التقنية أو الاقتصادية. ثانياً، كان من الممكن تقديم دراسة مقارنة بين النظام اليدوي الحالي والنظام المؤتمت المقترح لتوضيح الفوائد بشكل أكثر دقة. ثالثاً، لم يتم التطرق إلى كيفية تدريب العاملين على استخدام هذه الأنظمة الجديدة، وهو جانب مهم لضمان نجاح التطبيق. وأخيراً، كان من الممكن تقديم تحليل اقتصادي أكثر تفصيلاً لتكلفة تنفيذ النظام المؤتمت مقارنة بالنظام اليدوي.

The target this paper is to evaluate the lateral resistance on CWR stability in curves under the conditions the Syrian railway net and to determine the minimum radiaus depending upon the numerical solution of the energy equation.
The building sector is considered one of the leading sectors in energy-consumption. In addition to lighting, heating and cooling systems have become important consumers in all buildings (both residential, administrative, and service both private and public) ensuring a comfortable environment for staff and workers and improving productivity at the lowest possible cost. This research aims to study the control quantities of fresh and exhausted air in large halls and auditoriums, where the occupancy level changes. This is done by adjusting the amount of fresh and exhausted air according to the occupancy via CO2 sensors, which measure the ratio of CO2 in the targeted places, controlling the volume of fresh and exhausted air according to the number of available people. A case study was done to use control systems; final results and conclusions have been illustrated.
This research serves the process of organizing the traffic by reducing traffic congestion, especially at peak times to a minimum, presenting an effective method is not used locally to automate traffic lights adoption concepts, image processing, con trollers, communication. It is organizing image capture processes on a regular basis in all the streets leading to the traffic node, and then this image was taken to the central computer, which is processes each image by comparing them with all the pictures taken at a certain moment and based on the comparison, the Central Computer conclusion of the new chronological order to change traffic lights in all the streets then sends the new update to the controllers in each signal light which leads to re- Automatics these signals,by reducing bottlenecks to the minimum level and repeat imaging processes and modernization of signals throughout the day we can have access to a system to automate the traffic contract is close to the ideal note that by connecting traffic contract with each other and with the main central computer we can solve other problems like emergency and firefighting. Key words: a traffic node, signal processing, camera, network, processor, microcontroller.
As known the electric energy is one of the most important factor of development, but using it causes bad environmental impacts due to depending on fuel as the source of electrical generation. Using renewable energy is still limited and needs a huge fixed costs, so it is important to reduce electrical consumption by monitoring and controlling equipment to achieve its function with lower consumption. HVAC sector is the most consumption part in buildings, therefor any saving in this sector will affect manifestly on the total electrical consumption in the building and this is done by control system. Control systems are in continuous improving, so it is needed to exploit them in saving electrical energy. In this research, studying control of VAV system and designing fuzzy logic controller to drive supply fan in order to reduce its electrical consumption, this is performed through designing practical prototype of the supply fan with its tools and software which are designed to view the electrical energy saving which we gain it by using fuzzy logic controller.
reliance on new and renewable sources of energy has grown in order to obtain electric power without the use of traditional fossil fuel sources. And thus solve the problems of the global energy crisis and also maintain a clean environment, through the fight against the dangers of global warming and its negative results Wind power is considered as one of the most important of these alternative energies. We will work in this research in order to be able to control wind turbine with variable speed through pitch angle control in order to organize power and control the rotational speed in order to make the power ideal. Where we will be using a fuzzy controller to control pitch angle instead of the traditional controllers, which is expected to improve system response and provide ease in the application and modification and reduction in the cost. By reference study we came to the result showing that most previous studies in advanced wind energy systems have addressed to control wind turbine using conventional controllers from PI or PID type. Show we have the problem of the need to know the exact mathematical model of the system. Where traditional controllers of wind turbines that operate at variable speed are based on mathematical models which may be complex and non-linear and neglect often physical phenomena, for example, magnetic saturation which leads to complexity in the calculation and unexpected performance of the driven system. The proposed research aims to provide a complete study through modeling and simulation using the Matlab about the use of fuzzy controller to control the wind turbine where traditional controllers of type PI will be designed to control the pitch angle and to control the rotational speed and fuzzy PI controllers to control the pitch angle. Results will be get and discussed and conclusion will be extracted from them. Research Results showed that the fuzzy control improves transient state behavior, but the steady-state behavior is better controlled when we use PI controller. So and based on the result we got, the PI controller can't be replaced actually with the fuzzy controller.
