يهدف هذا البحث إلى تطوير آلية التحكم بالمعابر السطحية في الخطوط الحديدية التي تدار يدوياً, بالاعتماد على أنظمة التحكم الحديثة التي تتضمن المتحكمات و المعالجات الصغرية و أجهزة التحسس و المشغلات و الاتصالات و البرمجيات لتشكيل نظم مؤتمتة ذكية يمكن مراقبتها عن بعد. تم وضع خوارزمية التحكم و المخططات 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 في هذا المقال تصميم برنامجٍ يحاكي جميع الإجراءات و التحذيرات الموجودة عند المعبر السطحي الحقيقي بالاعتماد على لغة البرمجة الرسومية (Laboratory Virtual Instrumentation Engineering Workbench, LabVIEW) مع إمكانية المراقبة عن بعد عبر شبكة تراسل المعطيات من قبل سائق القطار أو المحطة, و تمكننا من تحديد اقتراب القطار من المعبر بدقة أكبر باستخدام الطريقة المؤتمتة, و تأمين كافة التنبيهات و الحماية اللازمة لمستخدمي الطريق و سائق القطار, و بالتالي زيادة الأمان و تقليل حوادث التصادم بين السيارات و القطار.
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.

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.
