يعتمد تطور البحث العلمي عادة على القياس. فبدون قياس لا يمكن معرفة مدى كفاءة أي نظام أو أداة مستحدثة. في هذه الورقة نعرض أدوات القياس التي يتم إستخدامها في تحديد كفاءة أنظمة إسترجاع المعلومات عموما و نركز على ما هو متوفر منها لقياس أنظمة إسترجاع النصوص العربية، ونبين مدى التطور التي أحدثه على مستوى إسترجاع النصوص العربية. تركز الورقة على عرض مجموعات الإختبار العربية المتوفرة حاليا, وتبرز القصور التي تعاني منه، وتظهر الحاجة الى وجود نجموعات اختبار عربية تتوافق مع واقع النصوص العربية الموجودة حاليا على شبكة المعلومات الدولية. كما نقوم بعرض مجموعة الإختبار التي قمنا بإعدادها لإختبار ظاهرة زيادة حجم النصوص العربية. ونبين أن زيادة الحجم في النصوص العربية يؤثر سلبا في مستوى آداء أنظمة الإسترجاع العربية. arabic 125 English 0

3D Holoscopic imaging (also known as Integral imaging) is a technique that is capable of creating and encoding a true volume spatial optical model of the object scene in the form of a planar intensity distribution by using unique optical components. It is akin to holography in that 3D information recorded on a 2D medium can be replayed as a full 3D optical model, Typically, moving from cylindrical lens to the next cylindrical lens is carried out knowing the lens width, Lw, which defines the translation of the camera along the x optical axis and hence the position of the new camera cylindrical lens. This new renderer is represented in the paper by the term integral ray tracing (IRT). In this paper, a method of generation 3D integral images camera file parameters is proposed. The camera file is an important part of the process of generating micro-images and set up the camera position. The method is mainly based on Parallel Multiprocessor Ray Tracing System adapted "Tachyon" as renderer. Experimental results show validation of the new algorithm and the lenticular lens can be set up and tested on small-balls, gears, room, tree and teapot scenes.

Biometric systems have a powerful potential to provide security for a variety of applications, systems are nowadays being introduced in many applications and have already been deployed to protect personal computers, Banking machines, credit cards, electronic transactions, airports, high security institutions like nuclear facilities, Military Bases and other applications like borders control, access control, sensitive data protection and on-line tracking systems. While biometrics may improve security in different environments and serve many purposes, biometric systems, like any other security system, have vulnerabilities and are susceptible to threats. they are susceptible to external vulnerabilities of biometric systems so that their weaknesses can be found and useful countermeasures against foreseeable attacks can be developed The increasingly high profile use of biometrics for security purposes has provoked new interest in researching and exploring methods of attacking biometric systems.
