The weigh feeders constitute an essential part of any production facility, where its control and supervision system is one of the important things that should be characterized by precision and reliability. From this research we will try to develop the unreliable control and supervision system of the weigh feeders in mills of raw materials department in Tartous cement and building materials company. The work Will focus on trying to avoid errors and problems that the old control system suffered in order to reach the best possible performance of weigh feeders, facilitate maintenance process and reveal the problems as they happen by proposing controlled weigh feeders by programmable logical controllers from SIEMENS corporation with processor (CPU 315-2 PN / DP), and design supervision and collection data system using software (WINCC Flexible sp3 2008). We'll apply the steps of the study practical on the weigh feeder of mill of raw materials, and we will conduct the necessary tests to ensure the validity and accuracy of the new control system, therefore the range of reliability.

Research summary
يهدف هذا البحث إلى تطوير نظام التحكم والمراقبة الخاص بقبانات التغذية لقسم مطاحن المواد الأولية في شركة طرطوس لصناعة الاسمنت ومواد البناء. يشكل نظام التحكم والمراقبة جزءاً أساسياً في أي منشأة إنتاجية، حيث يجب أن يتصف بالدقة والموثوقية. يعاني النظام القديم من مشاكل عديدة مثل تعقيد التوصيل الكهربائي، الاستجابة البطيئة، وغياب نظام مراقبة فعال. لذلك، يقترح البحث استبدال القبانات القديمة بأخرى حديثة واستخدام المتحكمات المنطقية القابلة للبرمجة (PLC) من شركة SIEMENS، وتصميم نظام مراقبة وتحصيل المعطيات باستخدام برنامج (WINCC Flexible sp3 2008). يتم تطبيق خطوات الدراسة بشكل عملي على قبان التغذية الخاص بمطحنة المواد الأولية، وإجراء الاختبارات اللازمة للتأكد من صحة ودقة النظام الجديد. يهدف البحث إلى تحسين الأداء وتسهيل عملية الصيانة وكشف العطل فور حدوثه، مما يؤدي إلى زيادة ساعات عمل الخط الإنتاجي وتقليل عدد مرات توقف المطحنة، وبالتالي زيادة الإنتاج اليومي والأرباح المادية.
Critical review
دراسة نقدية: يعتبر هذا البحث خطوة مهمة نحو تحسين أنظمة التحكم في المنشآت الصناعية، وخاصة في صناعة الاسمنت. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة. أولاً، لم يتم التطرق بشكل كافٍ إلى تكلفة تنفيذ النظام الجديد مقارنةً بالنظام القديم، وهو عامل مهم يجب أخذه في الاعتبار عند اتخاذ قرار التحديث. ثانياً، كان من الممكن تقديم المزيد من التفاصيل حول كيفية تدريب العاملين على استخدام النظام الجديد لضمان الانتقال السلس. أخيراً، يفضل أن يتم تقييم النظام الجديد على مدى فترة زمنية أطول لضمان استدامة الأداء العالي والموثوقية.

The administrative corruption phenomenon is global and is widely and deeplyrooted that takes a broad dimensions with various factors that are difficult to distinguish between them. The degree of coverage varies from one society to another. The deva stating effects and consequences of this phenomenon affects all life of all people, wastes resourcesand impede the fulfillment of responsibilities, functions and services, and thus constitute a system of sabotage and delay in construction and development process, not on the administrative and financial levels, but also political, economic, social and cultural levels, necessitating an effective independent regulatory system controls and follows-up practices of Ministers and officials in all ministries and institutions. Hence this research examines the role of administrative control in the fight against corruption in Syria industry companies (example about this companies Tartous companyfor Cement And Building materials Industry)in side and to evaluate the most important causes of corruption and the weakness and shortcomings in the regulatory procedures and processes in other side. The researcher addressed the concept of administrative supervision and its importance to the phenomenon of corruption and its causes, and how to address them, as well as the importance of control in the fight against corruption. The researcher concluded at the end of this research to a group of important conclusions: there are differences between control methods which have used tocombat corruption in Tartous Companyfor Cement And Building materials Industry, and the modern quantity methods and modern analyses control methods. In the end the researcher put forward a set of proposals and recommendations, including: the need to address the factors that contribute to the low level of control, and poor planning for effective control procedures, and lack of accountability and justice that could be the cause of corruption.
This paper presents a three phase shunt Active Power Filter (APF) for power quality improvements in terms of harmonics compensation. The compensation process is based on measure non-liner load currents and Active Filter currents, and then extract t he references from measured currents. Measured currents are then transferred from abc frame to d-q reference frame. A Synchronous Proportional Integral controller (Synchronous PI controller) is used. The control signals then drive the Pulse Width Modulation (PWM) routine, where its output controls the Voltage Source Inverter (VSI) switching devices. The performance of the Active Filter and the Synchronous PI controller is validated though the simulink results in MATLAB environment.
Traffic jam is a serious problem in our life, it causes waste of time and energy, conventional traffic light control system works with a fixed time and fixed cycle. This paper proposes an intelligent traffic light control system with a changeable gre en time and cycle depending on traffic density. Traffic parameters (cars’ numbers, density, flow) are collected by Loop Detectors located at each traffic signal, this data will be transmitted to the PLC controller then, PLC processes this data to produce controlling commands, it is also connected to a SCADA system which supervises the process and provides an automatic and manual control. The proposal system applies Green Wave method to connect between two junctions based on a real car velocity and sets priority for emergency car, when Loop Detector detects this car the program will be interrupted to open the traffic light needed. This intelligent system is experimented with conventional control system s’ data the obtained result is promising, it can reduce the green time, cycle time, and delayed time of each car at traffic light to its’ minimum value.
The main goal of this search is to design maximum solar power batteries charging system, Maximum power point tracking (MPPT) system is used in the photovoltaic (PV) system consisting of a buck-boost Direct Current DC/DC converter, which is controll ed by a microcontroller unit, The microcontroller is programmed with a simple and reliable MPPT called Incremental Conductance (InCond). The designed battery charger was tested, and the results obtained had insured about the permanent control on the battery charging. Comparison study was done, with PWM solar charger controller, it was obvious by The experimental results, that the battery get charged in a very short time period considering of the solar sun light hours per day, and the characteristics of the used solar panel, which confirm the reliable performance of the suggested charging system.
This paper shows how to design and implement control circuit in the movement of pv board to reach to maximal possible output, by designing a system to integrate several methods of of control with each other. During this work, we will design through formation a unified system combine control by light sensors, and control via data base on the other hand. In addition to compare pv angle in both ways. The proposed circuit designed, conduct a simulation, and implementation a miniature model simulates reality, and discussed the result to to conflict the advantage and the goal of using the proposed system. All that by using micro controller (PIC).
