Web accessibility concerns of building websites that are accessible by all people regardless of their ability or disability. The W3C Web Accessibility Initiative (WAI) has been established to raise awareness of universal access. WAI develops guidelines which can help to ensure that Web pages are widely accessible. Assistive technology is used to increase, improve, and maintain capabilities of disabled persons to execute tasks that are sometimes difficult or impossible to do without technical aid. Also it helps them achieve their scholar, professional and social activities. This paper exposes an approach to investigate accessible contents of educational websites to ensure and measure its compliance with accessibility standards for visually impaired people. This study focuses on studying existing standards and investigating its applicability on educational institute websites. This will increase accessibility on e-learning materials that are provided by educational institutes. In this paper a sample of websites at selected universities in Jordan are evaluated in terms of accessibility in comparison to some universities websites in England and Arabic region. Results show that accessibility errors of universities websites in Jordan, and Arab region exceed the ones in UK by 13 times, and 5 times consequently. Source

This paper presents a novel approach for computer viruses detection based on modeling the structures and dynamics of real life paradigm that exists in the bodies of all living creatures. It aims to develop an algorithm based on the concept of the artificial immune system (AIS) for the purpose of detecting viruses. The algorithm is called Virus Detection Clonal algorithm (VDC), and it is derived from the clonal selection algorithm. The VDC algorithm consists of three basic steps: cloning, hyper-mutation and stochastic re-selection. In later stage, the developed VDC algorithm is subjected to validation, which consists of two phases; learning and testing. Two main parameters are determined; one of them is setting the number of signatures per clone (Fat), while the other defines the hypermutation probability (Pm). Later on, the Genetic Algorithm (GA) is used as a tool, to improve the developed algorithm by searching the values of the main parameters (Fat and Pm) to reproduce better results. The results have shown that the detection rate of viruses, by using the developed algorithm, is 94.4%, whereas the detection rate of false positives has reached 0%. These percentages indicate that the VDC algorithm is sufficient and usable in this field. Moreover, the results of employing the GA to optimize the VDC algorithm have shown an improvement in the detection speed of the algorithm. © 2012 Elsevier B.V. Source

The current study examined some key developmental and individual differences in how elementary school-aged children evaluate sources of information. A sample of 130 children ages 6 to 9. years participated in a task designed to measure children's understanding of ways that claims can be distorted (i.e., biased decisions, skewed self-reports, and misleading persuasive claims). Children also completed several individual difference measures, including a brief intelligence task and an advanced social cognition measure (interpretive theory of mind). Overall, older children were less trusting and better than younger children at explaining the reasons to doubt sources that might provide distorted claims. Crucially, the results also suggest that beyond age, both general intelligence and advanced social cognitive skills play roles in children's ability to understand when and why they must doubt sources of distortion. © 2014 Elsevier Inc.

Summary The Optical Transpose Interconnection System (OTIS) optoelectronic interconnection network architecture is a promising attraction in the new era of parallel computing topologies because of its attractive topological properties. Recently, many enhancements were presented on OTIS topologies including the Extended OTIS-n-Cube interconnection networks. Therefore, all performance improvement characteristics of such a promising architecture need to be investigated; one of which is load balancing technique. This paper focuses on developing an efficient algorithm for load balancing on the promising Extended OTIS-n-Cube interconnection networks. The proposed algorithm is called Factor-Optical-Factor Exchange Model. Furthermore, this paper presents theoretical and experimental study on the proposed algorithm in terms of various parameters including execution time, load balancing accuracy, number of communication steps, and speed. Results show superiority of the proposed algorithm over the well-known Clustered Dimension Exchange Method (CDEM) algorithm in terms of execution time, number of communication steps, and speed, while maintaining the same level of accuracy.

Compression is a technique to minimize the quantity of image without excessively decreasing the quality of the image. Then, the translating of compressed image is much more efficient and rapidly than original image. Arithmetic and Huffman coding are mostly used techniques in the entropy coding. This study tries to prove that RLC may be added after Arithmetic coding as an extra processing step which may therefore be coded efficiently without any further degradation of the image quality. So, the main purpose of this study is to answer the following question "Which entropy coding, arithmetic with RLC or Huffman with RLC, is more suitable from the compression ratio perspective?" Finally, experimental results show that an Arithmetic followed by RLC coding yields better compression performance than Huffman with RLC coding. © Maxwell Scientific Organization, 2015. Source
