In this communication, we propose a miniaturized rectangular dielectric resonator antenna (RDRA) for wireless communication services (WCS). The studied structure consists of a rectangular Dielectric resonator stacked on a thick layer of dielectric material that has very high permittivity. The numerical analysis was done by two different electromagnetic modeling software; Ansoft HFSS and CST. The obtained results are given in terms of the reflection coefficients and the radiation characteristics of the proposed antenna. The proposed antenna design operates around 2.314 GHz and provides an impedance bandwidth of 20 MHz.

To manage large crowded events is a very challenging task nowadays. People are looking for solutions in which they can easily monitor the crowd, trace individuals, study formation and deformation patterns of the crowd. Millions of Muslims from around the world gather and perform Hajj in Makkah, Saudi Arabia in the 12th month of every lunar year. To monitor the crowd during Hajj is a great challenge. In this paper, we are proposing an identifiable crowd monitoring framework named iCrowd. This framework collect, identify, infer, analyze, store and retrieve the real-time location information of each of the pre-registered participants (pilgrims), and provides a digital view of crowd in near real-time. iCrowd framework is designed on a three-layer approach, device layer, middleware layer, and the application layer. We demonstrate our proposed framework with simulated data in the context of the event of Hajj.
如今,管理大型拥挤的活动是一项非常具有挑战性的任务。人们正在寻找能够轻松监控人群、追踪个体、研究人群形成和变形模式的解决方案。每年农历的第12个月,来自世界各地的数百万穆斯林聚集在沙特阿拉伯的麦加进行朝觐。在朝觐期间监视人群是一项巨大的挑战。在本文中,我们提出了一个可识别的人群监测框架,名为iccrowd。该框架收集、识别、推断、分析、存储和检索每个预注册参与者(朝圣者)的实时位置信息,并提供近乎实时的人群数字视图。iccrowd框架采用三层设计方法,即设备层、中间件层和应用层。我们在朝觐事件的背景下用模拟数据证明了我们提出的框架。

As blogs widely spread, the need to extract information is necessary in order to deal with different issues such as social, political, criminal and others. This research takes off from Gharehchopogh et al. [2], [3] who used the C4.5 and K-Nearest Neighbor (K-NN) algorithms to classify bloggers whether they are professional or otherwise from the Kohkilooyeh and Boyer Ahmad province in Iran. As a comparative measure, this paper proposed the Random Forest algorithm to perform the blog classification using the same dataset. The results showed that ensemble classification via Random Forest algorithm is able to produce higher precision of 88% as compared to 82% by the C4.5 algorithm and 84% by K-NN in the previous research.
随着博客的广泛传播,为了处理不同的问题,如社会、政治、犯罪等,需要提取信息是必要的。这项研究源于Gharehchopogh等人[2],[3],他们使用C4.5和k -最近邻(K-NN)算法对博客作者进行分类,无论他们是来自伊朗Kohkilooyeh和Boyer Ahmad省的专业人士还是其他专业人士。作为比较措施,本文提出了随机森林算法,使用相同的数据集进行博客分类。结果表明,Random Forest算法的集成分类精度达到88%,而之前的研究中C4.5算法的准确率为82%,K-NN的准确率为84%。

With diabetes patients doubling every year especially in the UAE there is a need to curb this epidemic and help those who are affected to live an active life. Continuous monitoring of health indicators ensures prompt medical attention and reduction in fatalities. The primary challenge to continuously monitor diabetes is that glucose level measurement requires invasive methods. Moreover, continuous monitoring must happen remotely and therefore would require computing and networking technologies that is seamless, real-time, high speed, and with large storage capacities. With the increasing penetration of smartphones, especially in the UAE, we propose a framework for continuous monitoring of diabetes on the smartphone platform. We also survey the state-of-the-art in continuous health monitoring.
糖尿病患者每年增加一倍,特别是在阿联酋,有必要遏制这种流行病,并帮助那些受影响的人过上积极的生活。持续监测健康指标可确保及时就医和减少死亡人数。持续监测糖尿病的主要挑战是血糖水平测量需要侵入性方法。此外,持续监控必须远程进行,因此需要无缝、实时、高速和具有大存储容量的计算和网络技术。随着智能手机的日益普及,特别是在阿联酋,我们提出了一个在智能手机平台上持续监测糖尿病的框架。我们还调查了持续健康监测方面的最新技术。

Candidate document retrieval for Arabic-based text reuse detection on the web 基于阿拉伯语的网络文本重用检测候选文档检索
Pub Date : 2016-11-01 DOI: 10.1109/INNOVATIONS.2016.7880048

Given an input document d, the problem of local text reuse detection is to detect from a given documents collection, all the possible reused passages between d and the other documents. Comparing the passages of document d with the passages of every other document in the collection is obviously infeasible especially with large collections such as the Web. Therefore, selecting a subset of the documents that potentially contains reused text with d becomes a major step in the detection problem. This paper describes a new efficient approach of query formulation to retrieve Arabic-based candidate source documents from the Web. We evaluated the work using a collection of documents especially constructed for this work. The experiments show that on average, 79.97% of the Web documents used in the reused cases were successfully retrieved.
给定一个输入文档d,本地文本重用检测的问题是从给定的文档集合中检测d和其他文档之间所有可能重用的段落。将文档d的段落与集合中所有其他文档的段落进行比较显然是不可行的,特别是对于Web这样的大型集合。因此,选择可能包含使用d的重用文本的文档子集成为检测问题中的一个主要步骤。本文描述了一种从Web检索基于阿拉伯语的候选源文档的高效查询方法。我们使用专门为这项工作构建的文档集来评估这项工作。实验表明,在重用案例中,平均79.97%的Web文档被成功检索。

The prevalence of social media, in the whole world and the Arab region in particular, has fueled the active engagement and participation of large swaths of the Arabic society in current events. Social media has been used to rally public opinion, increase awareness, spread information/misinformation, and organize large events. Data analysis is necessary to drive decision making, advertisement, political campaigning, counter-intelligence, etc. The sheer volume of data and number of users calls for automated methods for analysis and classification of Arabic text. In this paper, the problem of analysis and classification of Arabic news reports was studied. Innovative methods, based on lexical analysis and machine learning, were employed to tame the complexity of the Arabic language. Different classification algorithms were compared and the classification accuracy results are promising. This research presents seminal steps toward specialized analysis of Arabic crowd-sourced data and social media.

Social networks have gained a lot of interest in recent literature due to the huge amount of data that can be extracted from them. With this ever growing data, emerged the need for techniques to handle it and analyze it. Several papers have proposed many techniques to analyze a given social network from several aspects. Communities are a crucial property in social networks and community detection is considered one of the most important problems in these networks. For this, many papers have devised algorithms for detecting communities. The issue with these algorithms is that they only take into consideration the relation (or distance) between the nodes for detecting communities. In this paper, a new algorithm is proposed to detect communities based on the interests of the nodes rather than their distances from each other. The paper carries out some experiments to test how well is the clustering algorithm in terms of the accuracy and the execution time.
由于可以从中提取大量数据,社交网络在最近的文献中引起了很大的兴趣。随着数据的不断增长,出现了对处理和分析数据的技术需求。有几篇论文提出了许多技术来从几个方面分析给定的社会网络。社区是社交网络的一个重要属性,社区检测是社交网络中最重要的问题之一。为此,许多论文设计了检测社区的算法。这些算法的问题是,它们只考虑节点之间的关系(或距离)来检测社区。本文提出了一种基于节点兴趣而不是节点之间距离来检测社区的新算法。本文通过实验测试了聚类算法在准确率和执行时间上的表现。

In this paper, a reconfigurable triple notched-band UWB (Ultra Wide Band) antenna is presented. This compact antenna covers the frequency range from 3.1 GHz to 11.21 GHz. In order to reject a three frequency bands including the WiMAX (3.2–3.6 GHz), WLAN (5.15–5.85 GHz) and X band (7.25–8.395 GHz), we have inserted three different slots in the radiating patch; two C-shaped slots and a rectangular slot. To achieve the reconfiguration in the notched-band antenna, we have added a PIN diode in every slot to control these slots. The proposed antenna has a size of 30×30 mm2. The simulated results show a bandwidth with VSWR less than 2 and the radiation pattern is Omni-directional in XZ plane and bidirectional in YZ plane.
本文提出了一种可重构的三陷波超宽带(UWB)天线。这种紧凑型天线的频率范围从3.1 GHz到11.21 GHz。为了拒绝WiMAX (3.2-3.6 GHz), WLAN (5.15-5.85 GHz)和X波段(7.25-8.395 GHz)三个频段,我们在辐射贴片中插入了三个不同的插槽;两个c型槽位和一个矩形槽位。为了实现陷波带天线的重新配置,我们在每个槽中增加了一个PIN二极管来控制这些槽。该天线的尺寸为30×30 mm2。仿真结果表明,该天线的带宽驻波比小于2,在XZ平面呈全向辐射,在YZ平面呈双向辐射。

We investigate navigation algorithms, and specif­ically path planning, a fundamental function of autonomous robots. We formally address the issue of enhancing reliability of the widely-used A∗ path planning algorithm. In our step-wise refinement process, we capture successively more concrete specifications by transforming a high-level specification into an equivalent executable program. To elaborate an initial repre­sentation of the A∗ algorithm, we express it in an abstract and intuitive, yet formal, description. We use traditional mathematical concepts, such as sets, functions and predicate logic to capture this description. We then use the Z specification language to effect the transformation from the mathematical description into Z schemas, thus obtaining a formal specification. We use CZT to perform syntax and type checking and the Z/EVES tool to automatically prove some properties about the specification. Subsequently, we use the Z formal refinement theory to generate the implementation specification. This stage involves both data and operation refinement and is carried out in several basic sub-steps. A Java-based simulation prototype that mirrors the implementation specification is developed in order to demonstrate the applicability of our software development approach.
我们研究导航算法,特别是路径规划,自主机器人的基本功能。我们正式解决了提高广泛使用的A *路径规划算法的可靠性的问题。在我们的逐步细化过程中,我们通过将高级规范转换为等效的可执行程序来获取更具体的规范。为了详细说明A *算法的初始表示,我们用一种抽象、直观但正式的描述来表达它。我们使用传统的数学概念,如集合、函数和谓词逻辑来捕捉这种描述。然后,我们使用Z规范语言实现从数学描述到Z模式的转换,从而获得形式化规范。我们使用CZT执行语法和类型检查,并使用Z/EVES工具自动证明有关规范的一些属性。随后,我们使用Z形式细化理论来生成实现规范。这一阶段涉及数据和操作的细化,并分为几个基本的子步骤。为了演示我们的软件开发方法的适用性,开发了一个反映实现规范的基于java的模拟原型。
