There has been a clear and rapid development in signal processing systems, this development comes as a result of the availability of modern techniques in electronic systems and also as a result of achieving mathematical algorithms which were effective and perfect for signal processing. One of the most important application in signal processing is the digital image processing techniques. Sampling process is regarded as one of the basic and important operations in signal processing, from which we obtain samples that can represent the original image in perfect way. We present in this essay an affective algorithm which helps to arrange onedimensional samples from two- dimensional samples image. This enables to obtain a series of samples which has an ability of representing images with concern of their general structure. Also the neighborhood correlation of image points is respected, in addition to carrying out the subsequent treatments with less mathematical cost.

we seek to ensure laser stability , during its work , with time , and consistency of specifications and efficiency (returns), the cooling of the active medium and optical elements, are sensitive to the proper cooling method, in economic terms and in terms ease of work. Cooling technique helps prolonging the life of laser systems ,its stability and optimizing its operation. So the total cooling efficient lasers , Scientific and Industrial is essential when designing a laser and helps improving the specifications of lasers , gaseous or solid or semiconductor . In addition to that cooling has a good impact on the age of the laser , and safety of its use . The designed cooling system , necessary for a certain laser system , depends on the amount of heat generated from the system(in Joule), which must be removed by the cooling system to keep the laser at specific temperature
We extend the well Known Levi-Malcev decomposition theorem of finite dimensional Lie algebras to the case of pro-finite dimensional Lie algebras L = limLn (n ∈ N). We also prove that every finite dimensional homomorphic image of the Cartesian product of finite dimensional nilpotent Lie algebras is also nilpotent.
إعادة تشكيل وضعيات الإنسان ثلاثية الأبعاد من صورة واحدة ثنائية الأبعاد هي مشكلة تمثل تحديا للعديد من الباحثين. وفي السنوات الأخيرة، كان هناك اتجاه صاعد نحو تحليل الهندسة ثلاثية الأبعاد للكائنات بما في ذلك الأشكال والوضع بدلاً من مجرد تقديم مربعات مر بوطة. حيث أن التفكير الهندسي ثلاثي الأبعاد يؤدي إلى توفير معلومات أكثر ثراءً عن المشهد لمهام لاحقة عالية المستوى مثل فهم المشهد والواقع المعزز والتفاعل مع الكمبيوتر البشري، بالإضافة أيضًا تحسين اكتشاف الكائنات [3]، [4]. ولذلك كانت إعادة التشكيل ثلاثية الأبعاد مشكلة مدروسة جيداً، وكانت هناك العديد من التقنيات القابلة للتطبيق عمليًا مثل البنية من الحركة، والأنظمة الصوتية متعددة المقاييس ومستشعرات العمق، ولكن هذه التقنيات محدودة في بعض السيناريوهات. هنا في هذه الورقة، نعرض كيف تم التعامل مع المشكلة في العقود القليلة الماضية، وتحليل التطورات الأخيرة في هذا المجال، والاتجاهات المحتملة للبحث في المستقبل.
The oil reservoirs exploitation processes are one of very important steps of petroleum industry. The rentability of investor reservoir is related to correct planning and accurate understanding of rock properties and liquids flow in porous media. T he complexity of porous media contains hydrocarbon materials, with phases changes related to thermo-physiochemical phenomena, make the classical methods used to study the reservoir recovery are inaccurate and insufficient to predict the performance and behavior of reservoir. Recently, simulation and modeling are used to decrease the risks in the decision of the optimal recovery method, and achieve the best possible rentability. This method provides predictive capacity help us to better understanding of reservoir. By the suitable input data, we can solve the calibrated mathematical model analytically or numerically. We present in this research the formulation of mathematical model of isotropic-one dimension reservoir with single phase fluid flow. The numerical solution, the application of this model, and the mechanism of pressure diffusivity along productive formation, will be presented to simulate a reservoir with injection and production wells.
We prove that the sum A + B of closed subspaces A and B of the inverse limit of finite dimensional vector spaces, V = limVn (n ∈ N) over an algebraically closed field of characteristic 0 is closed. We extend also the basic fact that every ideal of a finite dimensional semisimple Lie algebra has a unique complement to the case of closed ideals of prosemisimple Lie algebras.
