The theme of the Abbasid Caliph and their children great interest in the knowledge and effective not only in the history of civilization but in the history of the humanity and the sublime values. Their interest and care for the scholar ulamaa and rendering help and encouragement by their caliphs were keen for science and knowledge because whatever the scholars have a status they cannot give help without and knowledge and the practice of their role in the interest and the care

In the spreading of the Internet, mobile smart devices, and interactive websites such as YouTube, the educational video becomes more widespread and deliberative among users. The reasons for its spread are the prevalence of technologies, cheap cost, and easy to use. However, these products often lack to the distinction in video production. By following videos of an educational channel on YouTube, some comments found to discuss the lack of the content presented to motivate the learners, which lead to reduce the viewers of the videos. Therefore, there is an important decision to find general standards for the design and production of educational videos. A list of standards has been drawn up to help those interested in producing educational

يعد الأمن البيئي موضوعاً حيوياً لا سيما في العصر الحديث، حيث بدأت تحديات التغير المناخي تتدهور وبسرعة متزايدة. وتزداد أهمية هذا الموضوع مع تصاعد تلك التحديات، أذ يتعين على الجميع لا سيما النساء منهم المشاركة في الحفاظ على البيئة لضمان استدامتها للأجيال الحالية والمستقبلية. ويُعد الحفاظ على البيئة والموارد الطبيعية أمراً ضرورياً لضمان استدامة الكوكب ومستقبل الأجيال القادمة. وفي هذا السياق، يأتي دور المرأة

Television white spaces (TVWSs) refer to the unused part of the spectrum under the very high frequency (VHF) and ultra-high frequency (UHF) bands. TVWS are frequencies under licenced primary users (PUs) that are not being used and are available for secondary users (SUs). There are several ways of implementing TVWS in communications, one of which is the use of TVWS database (TVWSDB). The primary purpose of TVWSDB is to protect PUs from interference with SUs. There are several geolocation databases available for this purpose. However, it is unclear if those databases have the prediction feature that gives TVWSDB the capability of decreasing the number of inquiries from SUs. With this in mind, the authors present a reinforcement learning-ba

In this research a proposed technique is used to enhance the frame difference technique performance for extracting moving objects in video file. One of the most effective factors in performance dropping is noise existence, which may cause incorrect moving objects identification. Therefore it was necessary to find a way to diminish this noise effect. Traditional Average and Median spatial filters can be used to handle such situations. But here in this work the focus is on utilizing spectral domain through using Fourier and Wavelet transformations in order to decrease this noise effect. Experiments and statistical features (Entropy, Standard deviation) proved that these transformations can stand to overcome such problems in an elegant way.
