Automatic Arabic sign language recognition (ArSL) and fingerspelling considered to be the preferred communication method among deaf people. In this paper, we propose a system for alphabetic Arabic sign language recognition using depth and intensity images which acquired from SOFTKINECT™ sensor. The proposed method does not require any extra gloves or any visual marks. Local features from depth and intensity images are learned using unsupervised deep learning method called PCANet. The extracted features are then recognized using linear support vector machine classifier. The performance of the proposed method is evaluated on dataset of real images captured from multi-users. Experiments using a combination of depth and intensity images and also using depth and intensity images separately are performed. The obtained results show that the performance of the proposed system improved by combining both depth and intensity information which give an average accuracy of 99:5%.

This paper presents a proposed adaptive technique for nonholonomic wheeled mobile robot (NWMR) using the sliding-mode control (SMC) method. The proposed control system based on the backstepping kinematic controller and PI sliding mode dynamic control. With an adaptive fuzzy logic to adjust adaptation gain of SMC for trajectory tracking control of nonholonomic mobile robot. Parametric and nonparametric uncertainties of mobile robot can be solved by using the proposed control which take advantages of stability and robustness in sliding mode control. The adaptation gain of SMC is adjusted by using Mamdani type inference system with adaptive tuning algorithm, which improves the adaptability for uncertainness and eliminate input chattering of the SMC. The stability and convergence of the control system are proved using Lypanouve criteria, and the comparison of the proposed controller with the other controllers ensures the validity and superiority of my own controller

Epilepsy is one of the most common a chronic neurological disorders of the brain that affect millions of the world's populations. It is characterized by recurrent seizures, which are physical reactions to sudden, usually brief, excessive electrical discharges in a group of brain cells. Hence, seizure identification has great importance in clinical therapy of epileptic patients. Electroencephalogram (EEG) is most commonly used in epilepsy detection since it includes precious physiological information of the brain. However, it could be a challenge to detect the subtle but critical changes included in EEG signals. Feature extraction of EEG signals is core trouble on EEG-based brain mapping analysis. This paper will extract ten features from EEG signal based on discrete wavelet transform (DWT) for epilepsy detection. These numerous features will help the classifiers to achieve a good accuracy when utilize to classify EEG signal to detect epilepsy. Subsequently, the results have illustrated that DWT has been adopted to extract various features i.e., Entropy, Min, Max, Mean, Median, Standard deviation, Variance, Skewness, Energy and Relative Wave Energy (RWE).

e-Government implementation and applications have gained a growing attention in the last decade. Countries seek to apply and extend the use of e-Government, and international organizations evaluate e-Government implementation and its impacts. The benefits of e-Government sound to be worthy while the costs of e-Government implementation sound to be costly. A clear implementation plan is a must to avoid financial loss. Countries should follow a road map compatible with their specific capabilities. Countries can depend on e-Government Maturity Models as guidelines for e-Government implementation. Available e-Government Maturity Models do not address the needs of individual countries. This article presents a new e-Government Maturity Model adjustable according to countries own capabilities through multi-layers, to ensure e-Government successful implementation within available resources. So this model is applicable for any given country, and it is even more useful for countries with limited resources.

Spectrum sensing is a key technology in establishing and developing cognitive radio networks. High efficiency, reliability and real time are the most important required parameters for accurate sensing process. Wideband sensing is the main factor to achieve reliability of sensing process. Shadowing, fading and aliasing problems of signals affect the performance of spectrum sensing process therefore; cooperative sensing is effectively used to overcome such problems. In this paper, a novel system is proposed to sense the free channels in a wideband spectrum over distributed cooperative sensing platform of Multi-Coset (MC) periodic non-uniform sampling technique with lower branches then lower complexity than conventional MC sampler. The proposed system is designed to receive a blind input wideband signal. In this work, a system consists of four cooperated nodes by sharing their sensing output data to achieve sensing process. The cooperation between cognitive radio users is executed via reporting channels that connect different nodes. The final decision is based on the majority rules of cooperative sensing. Simulation results illustrated that the probability of detection results from cooperative sensing is higher than the individual sensing by each user itself.

In this paper, we present a hybrid intelligent system based on Neutrosophic Logic (NL). In conjunction with Genetic Algorithm(GA) for classification. The neutrosophic logic is adapted for representing different forms of knowledge. GA is used to refine the generated neutrosophic rules. The performance of the proposed system is tested on three real-world databases Iris, Wine, and Wisconsin Diagnostic Breast Cancer (WDBC). In a series of experiments, we compare the performance of the proposed genetic neutrosophic rule-based classification system with that of the neutrosophic rule-based classification system. The performance of both classifiers is measured for the three real-world data sets. We have reached an average accuracy 98.39% in genetic neutrosophic against 94.78% for the corresponding neutrosophic.

Negotiation gets more attention in the field of business and becomes a more critical issue especially with the increasing use of services. In web services, negotiation is important for providers to meet consumers' expectation. For consumer and provider, security is an important concern. In this paper, an efficient genetic-based security negotiation approach for web service is proposed. A prototype is implemented for the proposed approach using JADE agent framework. To find a good fitness for the proposed genetic-based approach, we investigate different values for mutation rate and crossover rate. In addition, a comparison between the proposed approach, traditional time-based negotiation approach, and adapted traditional time-based negotiation approach is conducted. Furthermore, scalability tests, the execution time, and the success percentage of the three approaches are measured. From experimental results, the proposed approach outperforms the other two approaches.

Since Long Term Evolution (LTE) is a totally IP based cellular network hence, it only supports the packet switching (PS) function, which leads to the proposal of many alternatives for offering voice services over LTE to maintain the continuity of the most important cellular service over the new architecture of the celluar networks, these alternatives include Voice over LTE (VoLTE) which is the most cost and complexity ever for the voice service, also include the Circuit Switching FallBack (CSFB), the most widely deployed and currently exists alternative for voice service over LTE, meaning that it is the most preferable choice for many operators for its excellent circuit switching voice quality and SMS services delivering. The main drawback of the CSFB is the substantial call setup time delay, and if the worst fallback case happens, this time increased more, at this case the fallback happens at other MSC serving area than that MSC at which the registration was performed, therefore, at that case of fallback the Mobile Originating (MO) calls will need to perform inter-VLR location updating causing additional call setup time delay, on the other hand the Mobile Terminating (MT) calls will be dropped unless another functionality like Mobile Terminating Roaming Retry (MTRR) is adopted. This study is focused on the MTRR. MTRR is one of the 3GPP proposed solutions to solve the MT call dropping impact at MSCs boarders. Despite that MTRR found a satisfying solution for the problem of MT call dropping; on the other hand it made the call setup time nearly getting doubled. Therefore, it is important to analyze the fallback cases by giving a classification method for the fallback different cases, and the reasons cause that large additional call setup delay during CSFB. The paper also presents a new proposed sheme as an improved functionality to enhance the call setup time for both MT and MO calls during that case of fallback, caused by mismapping between Tracking Areas (TAs) and Location Areas (LAs) at MSCs serving area boarders, this new scheme with less procedures, reduces the call setup time for MT and MO calls at that case of fallback by finding a good method to perform the majority of the messages (causing that extra time) prior the MT/MO call procedures, and provide a solution for the limitations applied on MTRR, hence, improving the user quality of experience.
