Research summary
تقدم هذه الورقة نموذجًا رياضيًا للاقط كهرضوئي يمكن استخدامه في الدراسات والتطبيقات التي تعتمد على اللواقط الكهرضوئية. يعتمد النموذج على البارامترات المتوفرة في نشرة الصانع الخاصة باللاقط. تم بناء محاكاة للنموذج باستخدام برنامج LabView، مما يتيح بناء نماذج تجريبية تعتمد على مفهوم (Hardware-in-loop) لتطبيقات الهندسة العملية. تم اختبار المحاكي على لاقط كهرضوئي من نوع Shell SP150-PC، وأظهرت النتائج دقة عالية مع خطأ لا يتجاوز 1%. يثبت البحث فعالية استخدام LabView في محاكاة التطبيقات الهندسية المتعلقة بالطاقة الشمسية الكهرضوئية. أعد هذا البحث كجزء من رسالة الدكتوراه للمهندس أيمن إدريس بإشراف الدكتور جبر الرمحين ومشاركة الدكتور محمد منذر القادري في جامعة دمشق.
Critical review
تعد هذه الورقة مساهمة قيمة في مجال نمذجة ومحاكاة اللواقط الكهرضوئية باستخدام برنامج LabView، وهو ما يميزها عن الدراسات السابقة التي اعتمدت على Matlab. ومع ذلك، يمكن تحسين البحث من خلال تقديم مقارنة أكثر تفصيلية بين نتائج المحاكاة باستخدام LabView ونتائج المحاكاة باستخدام Matlab لتوضيح الفروقات بشكل أوضح. كما يمكن توسيع الدراسة لتشمل أنواعًا مختلفة من اللواقط الكهرضوئية لتحسين شمولية النتائج. بالإضافة إلى ذلك، يمكن تقديم توصيات أكثر تفصيلية حول كيفية تحسين النموذج الرياضي المستخدم بناءً على النتائج المستخلصة.

The study of electromagnetism in electrical machines is critical, especially in the field of design, investment and optimal performance. To achieve this, there are many ways in which varying degrees of accuracy . The main aim of this piece of resea rch is to study electromagnetic fields distribution in 3ph-induction machines using computational numerical methods and proper software, because these fields form the basic principle in machine 's work. It has been used the finite element method aided computer to solve magnetic equations (Maxwell equations). The simulation of magnetic field in induction machine performed by ANSYS-software. The paper shows technique for finding the electromagnetic fields distribution in all parts inside 3phinduction machine to get optimal design.
As a result of increased environmental awareness and interest in the effective protection of the environment from pollution, the restrictions have increased on the disposal of wastewater, and the need to the treatment plants has arisen to treat the wastewater prior to disposal in water bodies, whether water from either large or small communities. As a result of the importance of these facilities and cost of material massive construction, operation and maintenance. In order to facilitate the design process and calculate the initial cost it was issued some software that helps engineer in the design of the various parts of the station, and in order to choose the equipments and comparison between several alternatives in objective ways to choose the most appropriate. Some of these programs are dynamics. It has the ability to simulate the work of the treatment plant along the time and predict its efficiency and performance. STOAT is a software that aims to model and simulate wastewater and industrial wastewater treatment plant, and it is one of the newest technology that uses the latest developments in process modelling, simulation and a wide range of tools that simplifies the model building and simulation and give the results in graphics and tables, allowing us to examine the complex interactions between the various units within the station by interactive and dynamic methods and this is important for the effective design, operation and management of wastewater treatment plants. Hence, we take the coastal area as a case study where there are number of modern wastewater treatment plants of small agglomeration and is being work, as Kherbet al-Maaze wastewater treatment plant in Tartous. Using STOAT, the study shows a good efficiency and performance of Kherbet al-Maaze WWTP using (ASM1,ASAL1) models, and we could build several scenarios like arrival of high pollution load to the station in order to evaluate and predict its performance.
The present paper provides a mathematical dynamic modelling and analysis of a newly developed electrical power supply system for petrol cars. The main goal of this research work is to improve the economic operation of the car’s electric power supply aiming at fuel economy improvement and for less gases emission. The proposed scheme has been studied and investigated using MATLAB/SIMULINK(R) toolbox and C language. The dynamic behaviour of the proposed system has been analysed for two different driving cycles and the results showed a fuel economy improvement in the investigated two cases. It is shown that the proposed approach is very superior to the conventional one, which is widely used in most of public cars. However, it also shows very encouraging results in terms of fuel save and less gas emission. The main advantage of the method proposed is its applicability to any first or second hand low cost cars.
The simplified dynamic mathematical model of hybrid stepper motor was studied in this research. The aim was to simplify the study and to concentrate on certain topic of this subject. The mathematical model which describes their mechanical and elect rical dynamic behavior of the mentioned motor was done. Whereas, the mechanical model can be derived by Newton law, and electrical model can be derived by Kirchhoff law depending on the electrical equivalent circuit to each phase.
