تسعى هذه الدراسة إلى تحليل مسار التحالف الاستراتيجي بين الولايات المتحدة الأمريكية والمملكة العربية السعودية، وتتبع تطوره منذ عام 2015 حتى الوقت الراهن، في ضوء التحولات الإقليمية والدولية المتسارعة التي أفرزت جملة من المتغيرات الجوهرية في طبيعة العلاقة بين البلدين وأطر التفاعل بينهما، اذ تتناول الدراسة الأبعاد المتعددة لهذا التحالف، وفي مقدمتها البعد الأمني والعسكري، والبعد الاقتصادي، والبعد التكنولوجي، بوصفها الركائز الأساسية التي يقوم عليها، مع تسليط الضوء على انعكاسات هذا التحالف وتفاعلاته على منظومة الأمن الإقليمي في الشرق الأوسط، وقد خلصت الدراسة إلى أن التحالف الأمريكي السعودي، على الرغم مما اعتراه من تباينات وتحديات جوهرية في بعض المحطات، ما زال يحتفظ بأهميته الاستراتيجية بالنسبة للطرفين، وأنه يتجه نحو عملية إعادة صياغة مستمرة لأولوياته وآلياته التنفيذية، بما يتواءم مع التحولات الإقليمية المتلاحقة، وتصاعد التهديدات الأمنية، وتغيّر حسابات المصالح المشتركة بين الجانبين.
The aim of this paper is to present a new methodology to find the private key of RSA. A new initial value which is generated from a new equation is selected to speed up the process. In fact, after this value is found, brute force attack is chosen to discover the private key. In addition, for a proposed equation, the multiplier of Euler totient function to find both of the public key and the private key is assigned as 1. Then, it implies that an equation that estimates a new initial value is suitable for the small multiplier. The experimental results show that if all prime factors of the modulus are assigned larger than 3 and the multiplier is 1, the distance between an initial value and the private key

Show MoreIn this research, a study is introduced on the effect of several environmental factors on the performance of an already constructed quality inspection system, which was designed using a transfer learning approach based on convolutional neural networks. The system comprised two sets of layers, transferred layers set from an already trained model (DenseNet121) and a custom classification layers set. It was designed to discriminate between damaged and undamaged helical gears according to the configuration of the gear regardless to its dimensions, and the model showed good performance discriminating between the two products at ideal conditions of high-resolution images.
So, this study aimed at testing the system performance at poor s

Moreover, the most common problem that must be resolved in face emotion recognition systems is the feature extraction methods, which is comparable to traditional manual feature extraction methods. This traditional method is not able to extract features efficiently. In other words, there are redundant amount of features which are considered not significant, which affect the classification performance. In this work, a new system to recognize human facial emotions from images is proposed. The HOG (Histograms of Or

واجه الاطفال في العالم العربي اليوم ثورة تقنية سريعة يقف على راسها ما يعرف بالشبكة العالمية "الانترنت" حتى اصبحت واحدة من مفردات ثقافة الطفل في كثير من بلادنا العربية. وتزايد عدد منسوبيها مع الوقت، ومع هذه السرعة في الانتشار بينهم يوما بعد يوم، بدأت مرحلة جديدة من التساؤل حول مخاطر هذه الشبكة على الاطفال، وكبف يمكن استثمارها وكيف يمكن مواجهتها وحمايتهم من اخطارها؟ وحاولت الباحثتنا الاجابة على هذه التساؤلات ح

The study handled two parameter and three-parameter Weibull Distribution in addition to five –parameter Bi-Weibull distribution. The latter being very new and was not mentioned before in many of the previous references. This distribution depends on both the two parameter and the three –parameter Weibull distributions by using the scale parameter (α) and the shape parameter (b) in the first and adding the location parameter (g)to the second and then joining them together to produce a distribution with five parameters.
