3D Integral Imaging (also referred to as 3D Holoscopic imaging) methodology uses the principle of “Fly’s eye” and hence allows natural viewing of objects (i.e. fatigue free viewing); 3D-holoscopic technology produces images that are true optical models. This technology is based on physical principles with duplication of light fields. In this paper, a new method of visualization medical 3D integral images is proposed. Digital Imaging and Communications in Medicine data images (DICOM) taken from CT, MRI, PET and US images that produced by 3D-Doctor software to generate medical 3D integral images visualization of anatomy without glass in natural light. The method is mainly based on multiprocessor ray tracing system as renderer. The medical 3D content is captured in real time with the content viewed by multiple viewers independently of their position, without the needs of 3D eyewear. Experimental results show validation of the new algorithm and demonstrated that medical 3D integral images content can be displayed on commercially available multi-view auto-stereoscopic display. Medical 3D integral images content is parsed into multiprocessor ray tracing system, consequently, short time of medical 3D integral images movie of such pelvis scene is generated and displayed on PC screen, LCD and Holovizio display.

تناقش الورقة دراسة قبول موظفي الحكومة وتصوراتهم لإدخال انظمة المصادقة الحيوية Biometric” “Systems Authentication في مكان العمل. وتقترح دراسة العوامل التي تؤثر على قبول الموظفين للتقنية الجديدة حتى تسهل تبني واعتماد إستخدام التقنية الحيوية “Biometrics “في تطبيقات الحكومة الإلكترونية المختلفة. للتحقق من قبول الموظفين و استخدامهم لانظمة القياسات الحيوية “Systems Biometrics.“ الدراسات تشير إلى وجود فجوة رقمية وثقافية كبيرة بين الوعي باستخدام الموظفين للتقنية والحلول المفضلة التي تروج لها الإدارة لاستخدامها في المصادقة“Authentication “علي معاملات الحكومة الالكترونية وانعدام الثقة في التقنية واحتمالات سوء الاستخدام. دوافع الإدارة تعكس حاجة المديرين للنظر في هذه المسؤوليات لتضييق هذه الفجوات. يبدو واضحا أن التغلب على مقاومة الموظفين للتغيير, من استخدام الطرق التقليدية الي توظيف تقنيات جديدة هي قضية أساسية تواجه تنفيذ الانظمة الحيوية للمصادقة. استنادا إلى البحوث نوصي بأنه يجب ان تتم عملية التوعية والتوجيه حول الانظمة الحيوية قبل إدخال هذه التقنية وتقديمها في اي منظمة.

The advertising ecosystem faces major threats from ad fraud caused by artificial display requests or clicks, created by malicious codes, bot-nets, and click-firms. Currently, there is a multibillion-dollar online advertisement market which generates the primary revenue for some of the internet's most successful websites. Unfortunately, the complexities of the advertisement ecosystem attract a considerable amount of cybercrime activity, which profits at the expense of advertisers. Web ad fraud has been extensively studied whereas fraud in mobile ads has received very little attention. Most of these studies have been carried out to identify fraudulent online and mobile ads clicks. However, the identification of individual fraudulent displays in mobile ads has yet to be explored. Additionally, other fraudulent activity aspects such as hacking ad-campaign accounts have rarely been addressed. The purpose of this study is to provide a comprehensive review of state-of-the-art ad fraud in web content as well as mobile apps. In this context, we will introduce a deeper understanding of vulnerabilities of online/mobile advertising ecosystems, the ad fraud’s well-known attacks, their effective detection methods and prevention mechanisms. arabic 8 English 40
