Echo state network (ESN) is a relatively recent type of recurrent neural network that has proved to achieve state-of-the-art performance in a variety of machine-learning tasks. This robust performance that incorporates the simplicity of ESN implementation has led to wide adoption in the machine-learning community. ESN's simplicity stems from the weights of the recurrent nodes being assigned randomly, known as the reservoir, and weights are only learnt in the output layer using a linear read-out function. In this paper, we present a novel approach that combines ESN with support vector machines (SVMs) for time series classification by replacing the linear read-out function in the output layer with SVMs with the radial basis function kernel. The proposed model has been evaluated with an Arabic digits speech recognition task. The well-known Spoken Arabic Digits Dataset, which contains 8800 instances of Arabic digits 0-9 spoken by 88 different speakers (44 males and 44 females) was used to develop and validate the suggested approach. The result of our system can be compared to the state-of-the-art models introduced by Hammami et al. (2011) and P. R. Cavalin et al. (2012) , which are the best reported results found in the literature that used the same dataset. The result shows that ESN and ESNSVMs can both provide superior performance at a 96.91% and 97.45% recognition accuracy, respectively, compared with 95.99% and 94.04% for other models. The result also shows that when using a smaller reservoir size significant differences exist in the performance of ESN and ESNSVMs, as the latter approach achieves higher accuracy by more than 15% in extreme cases.
回声状态网络(ESN)是一种相对较新的递归神经网络，已被证明可以在各种机器学习任务中实现最先进的性能。这种强大的性能结合了ESN实现的简单性，在机器学习社区得到了广泛的采用。回声状态网络的简单性源于随机分配的循环节点的权重，称为存储库，并且权重仅在输出层使用线性读出函数学习。本文提出了一种将回声状态网络与支持向量机(svm)相结合的时间序列分类方法，将输出层的线性读出函数替换为具有径向基函数核的支持向量机(svm)。通过一个阿拉伯数字语音识别任务对该模型进行了验证。众所周知的阿拉伯语口语数字数据集包含8800个阿拉伯数字0-9的实例，由88个不同的说话者(44个男性和44个女性)使用，以开发和验证建议的方法。我们系统的结果可以与Hammami et al.(2011)和p.r. Cavalin et al.(2012)引入的最先进的模型进行比较，这是使用相同数据集的文献中发现的最佳报告结果。结果表明，ESN和esnssvm的识别准确率分别为96.91%和97.45%，而其他模型的识别准确率分别为95.99%和94.04%。结果还表明，当使用较小的油藏规模时，回声状态网络和esnssvm的性能存在显著差异，在极端情况下，后者的准确率达到15%以上。

Covert channels provide a medium for secret communication by exploiting caveats in common networking protocols to hide information exchanges within benign activities, without being detected by unsuspecting hosts and network firewalls. This makes covert channels a significant security concern. Therefore, it is of utmost importance to develop effective and comprehensive countermeasures. In general, the more secret data capacity a covert channel provides the higher its estimated threat level is, as it diminishes the time available to detect and disrupt such activities and prevent the information exchange. Hence, determining the capacity of a covert channel is important. However, most work in capacity estimation is specifically targeted at individual algorithms only, and thus is similarly in applicability. A general mathematical model that can predict the capacity of most algorithms is a key research need for effective covert channel prevention. In this paper, we have provided a general analytical model to determine the capacity of timing-based covert channels, and verified the model with computer simulations.

This paper introduces an approach that combines a set of semantic techniques to enhance traditional information retrieval for the Arabic language. The approach uses a set of linguistic techniques to deal with the Web content. It expands first the initial user's query with additional related words by using lexical semantic relations (synonyms) covered in Arabic WordNet thesaurus and by domain specific words and abbreviations collected from the corpus. Second, it makes use of linguistic methods to match semantically the query objective with the text content in the search results. The paper presents the approach used and also the implementation of the system. Experimental results show that semantic retrieval outperforms the traditional information retrieval which is based only on query keywords matching.

The physiotherapy and rehabilitation process is an expensive and time consuming affair. It also requires the direct supervision of the specialists for effective results. This high cost coupled with high demand prohibits many patients from receiving appropriate care. Moreover, the emotional and mental strain is excessive for patients and is counterproductive to the therapy. In this paper, we tackle the boredom aspect of the rehabilitation process wherein we develop a therapy system that uses computer games to emulate the therapeutic activities. We describe, in some details, the issues involved in the development process. Commercial of the shelf product is employed (the Xbox Kinect) so the cost is significantly reduced and the accessibility is greatly increased. The system was tested on children at a local hospital, and the feedback was highly encouraging. This work opens avenues for more research to be conducted in exercise development, movement emulation, and game design. Moreover, commercialization of these games is an interesting endeavor.

Modern Collaborative Virtual Environments (CVEs) are no longer developed as a one-piece to support specific applications such as online games, Virtual shopping, and E-health. In the traditional way, any modifications in VE applications require a service interruption in order to change both programming code and the supporting structure. As a consequence the ability to build and/or extend 3D VEs during the runtime becomes tedious task and requires long development time with advanced programming knowledge. Nowadays, it is important to offer an easy and rapid way for users and game developers to build and/or to extend CVE applications during the runtime without having the option to interrupt the system. In this paper, we propose a novel dynamic approach based on event atomic actions management, thanks to the state machine. We employ two different high-level scripting abstractions called class modeling and instance modeling. Class modeling controls what seems to be the simulation scenario, while, instance modeling controls objects and avatars behaviors in the virtual environment. Both class and instance modeling are implemented as a scripting plug-in and mastered respectively by atomic simulation and atomic behavior concepts. The atomic behavior concept is not only limited to object behaviors, it also handles the avatar facial animation parameters as defined in MPEG-4 SNHC standard. We evaluate the benefits of our proposed solution by describing a complex firefighter's game scenario. Through this scenario we explore the interaction between class and instance script modeling as well as the implication of atomic concepts on making code writing, when a VE application modification is required.

In this paper, we present a Lemma to achieve the upper bound of coverage for broadcasting relay in military ad hoc based wireless communications in critical battle field environment. Then, a scalable random directional broadcasting relay (RDBR) scheme based on the theorem presented in the Lemma is presented, so that a source node is able to effectively determine the forwarding nodes, especially when the density of nodes is high. The numerical results show that the proposed RDBR scheme associated with relative forwarding distance and angle is able to increase the successful delivery ratio up to 10% compared to conventional distance based broadcasting approaches.

Cloud computing and digital forensics are both developing topics and researching these topics requires an understanding of the main aspects of both cloud computing and digital forensics. In cloud computing it is necessary not only to understand its characteristics and the different services and deployment models but also to survey the underpinning elements of cloud computing such as virtualization and the distributed computing which are important to identify its impact on current digital forensics guidelines and procedures. Unlike papers discussing the challenges and opportunities presented by cloud computing in relation to digital forensics, in this paper, we will discuss the underpinning cloud computing elements which are required to provide forensics friendly cloud services. Furthermore, we suggest a set of questions that will aid in the process of cloud forensics analysis.

Digital in-painting is relatively a young research area, yet a large variety of techniques were proposed by the researchers to correct the occlusion. Image in-painting aims to restore images with partly information loss and tries to make in-painting results as these missing parts in such a way that the reconstructed image looks natural. Many different types of image in-painting algorithms exist in the literature. However no recent study has been undertaken for a comparative evaluation of these algorithms to provide a comprehensive visualization. This paper compares different types of image in-painting algorithms. The algorithms are analyzed in both theoretical and experimental ways, which have made the suitability of these image in-painting algorithms over different kinds of applications in diversified areas.

The widespread acceptance of SOA, as an architectural style to build solutions by composing loosely coupled, interoperable, distributed services, having separate concerns into solutions is promoting modeling of cross-organizations business processes (BPs). In these BPs, different participants from different organizations would like to participate and get involved in a collaboration to achieve a common goal. Meanwhile, Web Service Choreography Description Language (WS-CDL) is an XML-based language for describing peer-to-peer collaborations by defining from a neutral perspective their collaborative observable behavior. It defines a set of ordered message exchanges that accomplish a common business goal. Yet, this language lacks a standardized graphical description that would ease the understanding of the collaborative behavior, where different types of stakeholders need to communicate the collaboration. Our approach in this paper is to investigate the WS-CDL language and propose a graphical description by utilizing UML models.
SOA作为一种架构风格，通过将松散耦合的、可互操作的、分布式的服务组合到解决方案中来构建解决方案，它的广泛接受促进了跨组织业务流程(bp)的建模。在这些bp中，来自不同组织的不同参与者希望参与并参与到协作中，以实现共同目标。同时，Web服务编排描述语言(Web Service Choreography Description Language, WS-CDL)是一种基于xml的语言，通过从中立的角度定义可观察到的协作行为来描述点对点协作。它定义了一组有序的消息交换，以实现共同的业务目标。然而，这种语言缺乏标准化的图形化描述来简化对协作行为的理解，不同类型的涉众需要在协作中进行沟通。我们在本文中的方法是研究WS-CDL语言，并通过利用UML模型提出图形化描述。

This paper presents an efficient method for automatically annotating Arabic news stories with tags using Wikipedia. The idea of the system is to use Wikipedia article names, properties, and re-directs to build a pool of meaningful tags. Sophisticated and efficient matching methods are then used to detect text fragments in input news stories that correspond to entries in the constructed tag pool. Generated tags represent real life entities or concepts such as the names of popular places, known organizations, celebrities, etc. These tags can be used indirectly by a news site for indexing, clustering, classification, statistics generation or directly to give a news reader an overview of news story contents. Evaluation of the system has shown that the tags it generates are better than those generated by MSN Arabic news.
