In this essay we will study the using of OPC standard in adapting and removing the incompatibility between different components and devices in the control system . The OPC works as a third party that connect between devices (data sources) and programs that require this data , in case those programs may can't connect directly with that devices as a result of incompatibility between them. This incompatibility happens because these devices and programs are from different vendors or because the devices are very old and can't connect with newer programs. OPC will be a suitable solution for communications problems between the devices and programs in the control system, the OPC will connect to each of them and transfer data as good as if the connection between them is direct without any third party. The importance of this suggested technique will be shown practically in this essay through the implementation of it in solving one of the pumping control system problems in the Syrian Company for Oil Transport (SCOT). the suggestion was to use a OPC Server program (Kepware OPC Server) and a SCADA program ( WinCC flexible) instead of the old SCADA program and keep the old PLC devices , in this way we can get rid of the problems that appear in the old SCADA program and therefore we can ensure that the system will work as wanted with no problem. That will bring benefits to the company and results to high reliability in the work.

Research summary
تقدم هذه الدراسة استخدام تقنية 'OPC Server' لحل مشاكل الاتصال والمواءمة بين الأجهزة المختلفة في نظم التحكم المبرمجة. تعمل تقنية 'OPC' كوسيط يضمن الاتصال بين الأجهزة التي تعد مصدرًا للبيانات والبرامج التي تحتاج لقراءة هذه البيانات، وذلك عندما لا يمكن لهذه البرامج أن تتصل بشكل مباشر مع الأجهزة بسبب عدم التوافق بينها. تم تطبيق هذه التقنية في الشركة السورية لنقل النفط في بانياس لحل مشاكل منظومة التحكم بالضخ باستخدام برنامج 'Kepware OPC Server' بدلاً من برنامج المراقبة والتحكم القديم، مع الإبقاء على تجهيزات 'PLC' القديمة. أسفر التطبيق عن التخلص من المشاكل السابقة وضمان عمل النظام بشكل موثوق وفعال، مما أدى إلى فوائد اقتصادية كبيرة وموثوقية عالية في العمل.
Critical review
دراسة نقدية: تقدم الدراسة حلاً عملياً لمشاكل الاتصال في نظم التحكم المبرمجة باستخدام تقنية 'OPC Server'. ومع ذلك، يمكن القول أن الدراسة تفتقر إلى تحليل شامل للتحديات المحتملة التي قد تواجه تطبيق هذه التقنية في بيئات صناعية مختلفة. كما أن الدراسة لم تتناول بشكل كافٍ الجوانب الأمنية المتعلقة بنقل البيانات عبر 'OPC Server'، وهو جانب حيوي يجب أخذه بعين الاعتبار لضمان سلامة البيانات وحمايتها من الاختراقات. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت مقارنة بين 'OPC Server' وتقنيات أخرى مشابهة لحل مشاكل الاتصال في نظم التحكم.
Questions related to the research
  1. ما هي تقنية 'OPC' وكيف تعمل؟

    تقنية 'OPC' هي معيار عالمي يسمح للتطبيقات الصناعية بمشاركة البيانات بشكل سريع وموثوق، حيث تعمل كوسيط بين الأجهزة المصدرة للبيانات والبرامج التي تحتاج لقراءة هذه البيانات، مما يحل مشاكل عدم التوافق بين مكونات منظومة التحكم.

  2. ما هي الفوائد الاقتصادية لتطبيق تقنية 'OPC' في نظم التحكم؟

    تطبيق تقنية 'OPC' يوفر الكثير من مصاريف الصيانة الكبيرة التي كانت تُصرف على تأمين مستلزمات النظام القديم ومكوناته، كما يقلل من الحاجة إلى استبدال البنية التحتية القديمة، مما يؤدي إلى توفير كبير في الجهد والوقت والمال.

  3. ما هي المشاكل التي حلتها تقنية 'OPC' في الشركة السورية لنقل النفط؟

    تقنية 'OPC' حلت مشاكل الاتصال بين برنامج المراقبة والتحكم القديم وتجهيزات 'PLC' القديمة، مما أدى إلى التخلص من مشاكل الصيانة والتوافق وضمان عمل النظام بشكل موثوق وفعال.

  4. ما هي التحديات المحتملة التي قد تواجه تطبيق تقنية 'OPC' في بيئات صناعية مختلفة؟

    من التحديات المحتملة التي قد تواجه تطبيق تقنية 'OPC' هي الجوانب الأمنية المتعلقة بنقل البيانات، التوافق مع الأنظمة القديمة، والتكلفة الأولية لتطبيق التقنية وتدريب العاملين عليها.

The study aimed to look at the reality of the application of information and communication technology in small and medium enterprises in Syria, and stand on the most important requirements for effective use of this technology is effective. The stu dy sample included an administrative 96 in a number of small and medium enterprises in the cities of Latakia and Tartous during the first half of 2015 represented. the most prominent results of the study that the most important requirements for activating the use of technology in institutions under consideration is the availability of qualified trained and reduce the cost of the use of technology and the development of the necessary infrastructure, In addition to the type of activity, which plays an important role in the extent of the use of technology.
The self-incompatibility problem appeared in the Khodeiry variety widely grown In Lattakia. When this phenomenon was studied on the Khodeiry variety in two areas (Jabla and Boqa), the results showed that this variety is self-sterile, i.e. it is not able to pollinate itself or the flowers of other trees of the same variety, and its fruit is very small and do not contain seeds. The results also showed that the flower abortion percentage in the Khodeiry variety is due to the genetic factor which varies depending on the variety. The study investigated the self-compatibility in some olive varieties in order to use them as pollinizers for the Khodeiry variety with the result that the Gellet, Soufrawy and Sourany varieties are particularly compatible and have a high compatibility with the Khodeiry variety. Based on these results, it is recommended that pollinated varieties are grown between olive orchards to improve fruit and to increase its production.
The solution to many of the issues in Descriptive Geometry is easy when the issue in a particular case، so methods are used Descriptive Geometry to turn the issue of the general case to the special case to facilitate the resolution، and usually th is is easy in some of the issues and the need for a set of steps in other issues، so we thought to take advantage of computer programs to solve some of these issues directly، or we will provide programming model on one of the issues to be resolved to facilitate and reduce the steps needed to reach a solution.
The problem of designing NLP solvers for math word problems (MWP) has seen sustained research activity and steady gains in the test accuracy. Since existing solvers achieve high performance on the benchmark datasets for elementary level MWPs containi ng one-unknown arithmetic word problems, such problems are often considered solved'' with the bulk of research attention moving to more complex MWPs. In this paper, we restrict our attention to English MWPs taught in grades four and lower. We provide strong evidence that the existing MWP solvers rely on shallow heuristics to achieve high performance on the benchmark datasets. To this end, we show that MWP solvers that do not have access to the question asked in the MWP can still solve a large fraction of MWPs. Similarly, models that treat MWPs as bag-of-words can also achieve surprisingly high accuracy. Further, we introduce a challenge dataset, SVAMP, created by applying carefully chosen variations over examples sampled from existing datasets. The best accuracy achieved by state-of-the-art models is substantially lower on SVAMP, thus showing that much remains to be done even for the simplest of the MWPs.
The problem of outliers values is considered one of the important objects that affect the estimation of statistical intermediaries specially regression model intermediaries. We have tried in this research to introduce a comprehensive study Of the outliers and some ways of exploring and treating them. In addition to , we have put anew algorithm that helps to find the estimation of the outliers. This matter helps in treating outliers and getting exact results in regression analysis.
