2017 2nd International Conference on Anti-Cyber Crimes, ICACC 2017 | Year: 2017

With the increased use of ICT in different areas of contemporary life, the widespread access to the Internet, and the use of social media, individuals and organisations face constant threats and challenges resulting from the bad consequences of cybercrimes. Research shows that the incidence of cybercrime is increasing. In response to these threats and challenges, government and law enforcement agencies in different countries around the world have enacted anti-cybercrime laws. The aim of this paper is to compare the existing anti-cybercrime laws in the Gulf Cooperation Council (GCC) countries. It adopts a comparative research approach. According to the findings, although these countries share common traditions and Islamic, legal, cultural and social values, there are some similarities and differences in their anti-cybercrime laws. Furthermore, there is variation in the scope of addressing cybercrimes. The paper highlights some issues related to these laws and provides suggestions for improvement and future research. © 2017 IEEE.

The bottleneck traveling salesman problem is to find a Hamiltonian circuit that minimizes the largest cost of any of its arcs in a graph. A simple genetic algorithm (GA) using sequential constructive crossover has been developed to obtain heuristic solution to the problem. The hybrid GA incorporates 2-opt search, another proposed local search and immigration to the simple GA for obtaining better solution. The efficiency of our hybrid GA to the problem against two existing heuristic algorithms has been examined for some symmetric TSPLIB instances. The comparative study shows the effectiveness of our hybrid algorithm. Finally, we present solutions to the problem for asymmetric TSPLIB instances. © 2013 ACM.

Research demonstrates that deaf individuals are undereducated and most of them are illiterate or at least semi- illiterate. Educating individuals with disabilities, in general, is a good investment. It doesn't only reduce welfare costs and future dependence; it reduces current dependence and frees other household members from caring responsibilities, as well as allowing them to increase employment or other productive activities. In this scope, a national funded project is launched to develop an environment for teaching and learning for Saudi deaf, using both automatic translation from Arabic to Saudi Sign Language and 3D animation techniques called Avatars. As part of the project, this paper presents the development of educational material to allow access to vital information for deaf people by presenting essential knowledge needed in their daily lives in an easy manner to grasp and comprehend. Resources for the subject of Islamic Education is collected and indexed based on levels and depths of information to accommodate needs of various types of users targeted by our works. © 2012 Springer-Verlag.

Background and aim. Effects of Ramadan fasting on health are important. Its effects on arterial pulse pressure (PP), lipid profile and oxidative stress were characterized in hypertensives. Methods. PP, indices of lipid profile and oxidative stress were measured pre-, during and post-fasting in equal (40 each), sex- and age-matched groups (age 55 ± 5 years) of hypertensives (HT) and controls (C). Results. Fasting reduced PP significantly by 17.2% and insignificantly by 9.3% in the HT and C groups, respectively. Total cholesterol (TC) was lowered insignificantly by 11.7% and 4.7% in the HT and C patients, respectively. Triglycerides (TG) and malondialdehyde (MDA) were significantly lowered by: TG: 24.5% and 22.8%; MDA: 45.6% and 54.3%; while glutathione (GSH) elevated by 56.8% and 52.6% in the HT and C groups, respectively. High-density lipoproteins (HDL) were raised significantly by 33.3% and insignificantly by 6.7%, whereas low-density lipoproteins (LDL) decreased significantly by 17.7% and insignificantly by 4.0% in the HT and C groups, respectively. At 6 weeks post-fasting, MDA remained significantly lower than the pre-fasting level by 24.3% and 25.7%, and GSH higher by 30.2% and 26.3% in the HT and C groups, respectively, while PP and TC returned to pre-fasting values in both groups. The post-fasting, HDL was significantly higher by 20.3% and LDL lower by 12.0% than the fasting levels in the HT patients. Conclusion. Fasting improves PP and lipids profile and ameliorates oxidative stress in hypertensives. © 2014 Scandinavian Foundation for Cardiovascular Research.

This paper presents detailed review in the field of off-line cursive script recognition. Various methods are analyzed that have been proposed to realize the core of script recognition in a word recognition system. These methods are discussed in view of the two most important properties of such systems: size and nature of the lexicon involved and whether or not a segmentation stage is present. Script recognition techniques are classified into three categories: firstly, segmentation-free methods or holistic approaches, that compare a sequence of observations derived from whole word image with similar references of words in the small lexicon. Secondly, segmentation-based methods, that look for the best match between consecutive sequences of primitive segments and letters of a possible word similar to human-like reading technique, in which secure features found all over the word are used to boot-strap a few candidates for a final evaluation phase; thirdly, hybrid approaches. Additionally, different feature extraction techniques are elaborated in conjunction with the classification process. In this scenario, implications of single and multiple classifiers are also observed. Finally, remaining problems are highlighted along with possible suggestion and strategies to solve them.

Time-integrated spatially-resolved emission spectroscopy, in the deep vacuum ultraviolet (VUV) region, of laser-produced plasmas was employed for the quantitative determination of the carbon content in steel targets. Six prominent VUV carbon spectral lines, representing three different ionization stages, were selected and proved to be spectral interference free. Several experimental parameters and conditions, including the focusing lens type, the laser power density, the background atmosphere and the pressure, were optimized, leading to an optimum limit of detection for carbon of 1 ppm obtained with the 97.70-nm CIII spectral line. Thus article presents a summary of the overall results obtained from this study.

We consider the clustered travelling salesman problem in which vertices (except the starting vertex) of the network are divided into some prespecified clusters. The problem is to find a least cost Hamiltonian cycle (tour) in which vertices of any cluster are visited contiguously and the clusters are visited in the prespecified order. The problem is NP-hard and it arises in practical transportation and sequencing problems. This paper develops a lexisearch algorithm for obtaining exact optimal solution to the problem. The efficiency of the algorithm against an existing algorithm to the problem has been examined for asymmetric TSPLIB instances of various sizes and clusters. Finally, we present solutions to some symmetric TSPLIB instances. © 2012 Operational Research Society of India.

A simple lexisearch algorithm that uses path representation method for the asymmetric traveling salesman problem (ATSP) is proposed, along with an illustrative example, to obtain exact optimal solution to the problem. Then a data-guided lexisearch algorithm is presented. First, the cost matrix of the problem is transposed depending on the variance of rows and columns, and then the simple lexisearch algorithm is applied. It is shown that this minor preprocessing of the data before the simple lexisearch algorithm is applied improves the computational time substantially. The efficiency of our algorithms to the problem against two existing algorithms has been examined for some TSPLIB and random instances of various sizes. The results show remarkably better performance of our algorithms, especially our data-guided algorithm. © 2011 Zakir Hussain Ahmed.

In this article, we discuss different approaches and mechanisms implemented in the social force model regarding its role in obtaining real-life data. In crowd evacuation processes, preserving normal crowd density at an exit is crucial. Here, we introduce a new mechanism for the reproduction of specific flow rate within the range stated in the literature. For the implementation of this mechanism into the social force model, an association between the pedestrians' social responsibility to relieve any unusual crowd density in front of an exit and a reduction in their competition behavior is presented, where the pedestrians' perception of what is behind them is the main factor in this association. Accordingly, a model is proposed for rear perception subject to the production of the fundamental diagram and the specific flow rate, while conserving the inter-pedestrian dynamics by which the social force model is characterized. Simulations are conducted to demonstrate the validity of this mechanism. © 2014 IOP Publishing Ltd and SISSA Medialab srl.

Methods: The current study was carried out in the city of Benha, Egypt, during the period from July 12, 2012 to October 4, 2012. This corresponds to 22 Shaban 1433 to 18 Dhul Al-Qi’dah 1433 in the Islamic Calendar. Two equal, sex- and age-matched groups (n = 40 each; age 55 ± 5 years) of non-diabetic subjects (ND group) and diabetic patients (D group) were recruited for this study. Parameters of glycemic control, lipid profile, and oxidative stress were measured pre-, during and post-fasting.Purpose: The effects of Ramadan fasting on public health are important. The present study characterized the metabolic effects of Ramadan fasting and evaluated its influence on oxidative stress in diabetic patients.Results: Ramadan fasting reduced fasting blood glucose (FBG) insignificantly by 5.8 % and significantly by 23.0 % in the (ND) and (D) groups, respectively. Serum triglycerides (TG) and malondialdehyde (MDA) were lowered significantly by: TG (22.8, 22.1 %), MDA (54.3, 46.6 %), and total cholesterol (TC) and low-density lipoproteins (LDL) insignificantly by: TC: (4.7, 6.1 %), LDL: (4.0, 5.1 %), whereas high-density lipoproteins (HDL) were raised significantly by 6.7 % and insignificantly by 2.2 %, and blood glutathione (GSH) significantly by 52.6 and 59.4 %, in the (ND) and (D) groups, respectively. At 6 weeks post-fasting FBG, TG, TC, HDL, and LDL returned to levels indistinguishable from their baseline values in both groups, while MDA was maintained significantly lower by (25.7, 22.7 %), and GSH significantly higher by (26.3, 31.3 %), in the (ND) and (D) groups, respectively.Conclusions: Ramadan fasting improves glycemic control and lipids profile and alleviates oxidative stress in diabetics. © 2014, Springer-Verlag Berlin Heidelberg.
