Deep Web is an important topic of research. According to the deep web pages' complicated structure, extracting content is a very challenging issue. In this paper a framework for efficiently discovery deep web data records is proposed. The proposed framework is able to perform crawling and fetching relevant pages related to user's text query. To retrieve the relevant pages this paper proposes a similarity method based on the improved weighting function (ITF-IDF). This framework utilizes the web page's visual features to obtain data records rather than analyze the source code of HTML. To accurately retrieve the data records, an approach called layout tree is exploited. The proposed framework uses Noise Filter (NSFilter) algorithm to eliminate all noise like header, footer, ads and unnecessary content. Data records are defined as a similar layout visual blocks. To cluster the visual blocks with similar layout, this paper proposes a method based on appearance similarity and similar shape and coordinate feature (SSC). The experiment results illustrate that the framework being proposed is better than previous data extraction works.
深网是一个重要的研究课题。由于深层网页结构复杂,内容提取是一个非常具有挑战性的问题。本文提出了一种高效发现深度网络数据记录的框架。该框架能够抓取和获取与用户文本查询相关的页面。为了检索相关页面,本文提出了一种基于改进加权函数(ITF-IDF)的相似性方法。该框架利用网页的可视化特性来获取数据记录,而不是分析HTML的源代码。为了准确地检索数据记录,采用了一种称为布局树的方法。该框架使用噪声过滤器(NSFilter)算法来消除所有噪声,如页眉、页脚、广告和不必要的内容。数据记录被定义为类似可视化块的布局。为了对具有相似布局的视觉块进行聚类,本文提出了一种基于外观相似性和相似形状与坐标特征的聚类方法。实验结果表明,所提出的框架优于以往的数据提取方法。

Cryptography and cryptographic primitives are widely considered to be the most important fundamental of blockchain that provide secure and anonymity guaranteed decentralized solutions. In the history of papers study cryptographic primitives used in blockchain, the focus has always been in the use cases of blockchain in different aspects of industry, example health care, IoT, information security, consensus building systems and some other fields. To the best of our knowledge, current cryptography techniques used in blockchain, or still theoretical but the security proof can be proven under certain security assumption, so can be used in blockchain has gathered numerous awareness in the last five years. In this paper, we fully review and analysis some cryptographic techniques used in designing a distributed consensus protocol that is efficient, decentralized, and flexible as a framework which are already used in blockchain. Take in consideration deploying a permissioned consensus like delegated proof-of-stack (DPoS) in the decentralized IOT applications is hard. The IOT systems needs to consider a larger data size and a larger span deployment. With this in mind we point to the special challenge for the IOT applications related to blockchain. Several modern cryptography techniques have been adopted to enhance the consensus process with respect to the computational overhead vs communication overhead and storage cost. Additionally, we re-examine non-interactive signature and public key aggregation in digital signature on different messages types and present a change in the aggregation scheme, as far as we know this is the first time that pairing become more faster in verify signatures, and to enable more transaction in the block.
密码学和密码学原语被广泛认为是区块链最重要的基础,提供了安全和匿名保证的去中心化解决方案。在研究区块链中使用的密码原语的论文历史中,重点一直放在区块链在不同行业方面的用例上,例如医疗保健、物联网、信息安全、共识构建系统等领域。据我们所知,目前用于区块链的加密技术,还是理论性的,但其安全性证明可以在一定的安全假设下证明,因此可以用于区块链在过去的五年里已经聚集了众多的意识。在本文中,我们全面回顾和分析了用于设计分布式共识协议的一些加密技术,该协议作为已经在区块链中使用的框架,具有高效,分散和灵活的特点。考虑到在分散的物联网应用程序中部署像委托堆栈证明(DPoS)这样的许可共识是困难的。物联网系统需要考虑更大的数据量和更大的跨度部署。考虑到这一点,我们指出了与区块链相关的物联网应用的特殊挑战。在计算开销、通信开销和存储成本方面,采用了几种现代加密技术来增强共识过程。此外,我们重新研究了不同消息类型的数字签名中的非交互式签名和公钥聚合,并提出了聚合方案的变化,据我们所知,这是第一次在验证签名时配对变得更快,并且在块中启用更多的事务。

Reliability is a very important aspect in electronic components used in the Automotive industry. Due to the harsh environments in this industry, Printed Circuit Board (PCB) tracks are a very common cause of failure. This paper proposes a scheme that will increase the reliability of chip-to-chip interconnections. The scheme relies on the availability of unused microcontroller IO ports. It is shown how to implement a 1-out-of-2 (or even 1-out-of-3) fault-tolerant communication channel. To illustrate the advantage of the proposed scheme, communication channel reliability is calculated with and without fault tolerance and a use case indicates that the increase in reliability can be significant.
可靠性是汽车工业中电子元件的一个非常重要的方面。由于这个行业的恶劣环境,印刷电路板(PCB)轨道是一个非常常见的故障原因。本文提出了一种提高芯片间互连可靠性的方案。该方案依赖于未使用的微控制器IO端口的可用性。演示了如何实现1 / 2(甚至1 / 3)容错通信通道。为了说明该方案的优点,计算了有容错和无容错情况下的通信信道可靠性,一个用例表明,可靠性的提高是显著的。

With the rapid development of Big Data and the necessity for analyzing their huge volumes, the issue of Unstructured Data analysis in social media was appeared. The Data analysis process is very important in all fields as to make decisions at the right time and over certain facts. The usage of social media has become the latest trend in today's world in which users send, read posts known as ‘message’ and communicate with various groups. Users are sharing their regular life, posting their views on everything like products and locations. This data is extremely unstructured, making it hard to analyze. Machine learning technology offers important data preparation techniques for processing large-scale data to extract knowledge, e.g., classifying data. Extract useful information from social media data is essential to success in the big data age. Therefore, fresh strategies are needed for handling huge quantities of unstructured data and finding the hidden information in these data and achieving better data analysis outcomes, In this paper, the proposed framework recommends the construction of a machine-learning model capable of analyzing unstructured text data with highly accuracy compared to other machine learning algorithms.
随着大数据的快速发展和对海量数据进行分析的需要,社交媒体中的非结构化数据分析问题应运而生。数据分析过程在所有领域都是非常重要的,因为它可以在正确的时间和特定的事实上做出决定。社交媒体的使用已经成为当今世界的最新趋势,用户在社交媒体上发送、阅读被称为“消息”的帖子,并与各种群体进行交流。用户正在分享他们的日常生活,发布他们对产品和地点等一切事物的看法。这些数据是非结构化的,很难分析。机器学习技术为处理大规模数据提取知识提供了重要的数据准备技术,例如对数据进行分类。从社交媒体数据中提取有用信息是在大数据时代取得成功的关键。因此,需要新的策略来处理大量的非结构化数据,并发现这些数据中的隐藏信息,从而获得更好的数据分析结果。本文提出的框架建议构建一种机器学习模型,与其他机器学习算法相比,该模型能够以较高的精度分析非结构化文本数据。

Realthcare is one of the main domains where sharing information is an essential requirement. Medical information systems store all the clinical data in many different kinds of formats. Subsequently, there is an urgent requirement to address the semantic interoperability problem. This paper proposes a fuzzy-ontology framework that could integrate most existing EHR different data models. In the proposed framework, each input source is represented into an ontology representation. Those data sources may be relational databases, XML documents, Excel spreadsheets, CSV files, or EHRs standards. Second, all those output ontologies are merged and combined in only one ontology. DL-Query Protégé plug-in is used for providing specific queries. All the results are explained with the help of screenshots. We expect our framework to be a step towards solving the specific problem without losses of data and semantics.

Discretizing continuous attributes is one essential and important data preprocessing step in data mining. Various data mining techniques are designed to be applied to discrete attributes. There have been tremendous efforts to propose discretization techniques with different characteristics. However, a clear pathway that can guide the choice of the needed discretization technique for different types of datasets is lacking. This paper proposes a taxonomy based on the existence of class information and relationship between attributes in the analyzed dataset. We review different discretization techniques classified according to the proposed taxonomy. The proposed taxonomy emphasizes the advantages and disadvantages of each discretization technique to be able theoretically to find a suitable discretization technique for a particular dataset.
离散化连续属性是数据挖掘中一个重要的数据预处理步骤。各种数据挖掘技术被设计用于离散属性。为了提出具有不同特性的离散化技术,人们付出了巨大的努力。然而,缺乏一个明确的途径,可以指导选择不同类型的数据集所需的离散化技术。本文提出了一种基于类信息存在性和属性间关系的分类方法。我们回顾了根据所提出的分类分类的不同离散化技术。提出的分类法强调了每种离散化技术的优点和缺点,以便能够从理论上找到适合特定数据集的离散化技术。

An EBG is designed at the ground plane of a pentagon microstrip patch antenna for detecting brain tumors. Two circular EBG types have been introduced. The first type is a rectangular lattice of holes which produced an increase in S11 by 19% at the same resonance frequency which is 3.9 GHz with and without tumor. The second one is a squared lattice of holes that presented an increase of 27 % in S11. It also provides a 2.9% shift in the resonant frequency at −10 dB on a head phantom with a brain tumor compared to without a tumor. The electric field, magnetic field, and current density are calculated in each type of EBG. A remarkable difference has been observed between with and without tumor especially on the squared lattice. One-, two-and four- elements linear antenna arrays are designed to be put at a 10-mm distance from the head phantom. The purpose of antenna arrays is to provide sufficient energy to penetrate human tissues. The directivity was increased as 6.65 dB, 8.5 dB, and 12 dB in one element, two elements, and four elements respectively. The S11 is calculated for each antenna on a head phantom with and without tumor. The S11 values are increased by 1.05dB, 2.73dB, and 4dB for the three cases respectively. Finally, the E and H fields, current density and specific absorption rate SAR are also calculated.
在五边形微带贴片天线的地平面上设计了一种用于脑肿瘤检测的EBG。介绍了两种环形心电图类型。第一种类型是矩形晶格孔,在3.9 GHz的共振频率下,有和没有肿瘤的S11增加了19%。第二个是方形的孔晶格,在S11中增加了27%。与无肿瘤相比,有脑瘤的头部幻像在−10 dB时共振频率偏移2.9%。计算了每种EBG的电场、磁场和电流密度。在有肿瘤和没有肿瘤之间观察到显著的差异,特别是在方阵上。一单元、二单元和四单元线性天线阵列被设计放置在距离头部模体10毫米的距离处。天线阵列的目的是提供足够的能量来穿透人体组织。一种元素、二种元素和四种元素的指向性分别增加6.65 dB、8.5 dB和12 dB。S11是对有和没有肿瘤的头部幻影上的每个天线进行计算的。三种情况下的S11值分别增加了1.05dB、2.73dB和4dB。最后,计算了E场和H场、电流密度和比吸收率SAR。

The directivity was increased as 6.65 dB, 8.5 dB, and 12 dB in one element, two elements, and four elements respectively. The S11 is calculated for each antenna on a head phantom with and without tumor. The S11 values are increased by 1.05dB, 2.73dB, and 4dB for the three cases respectively. Finally, the E and H fields, current density and specific absorption rate SAR are also calculated.","PeriodicalId":136643,"journal":{"name":"2019 14th International Conference on Computer Engineering and Systems (ICCES)","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115005531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multivariate statistical process monitoring techniques have been developed to detect and isolate abnormal situations of modern industrial processes that became more complicated and are classified as large-scale systems. Several fault detection and isolation indices have been proposed for multivariate statistical process monitoring. This paper discusses these indices and compare their performances by applying for an industrial benchmark, the Tennessee Eastman chemical process. The efficiency of these indices is measured by four key performance indicators (KPIs), i.e., fault detection time delay, false alarm rate, missed detection rate, correct fault isolation.
多元统计过程监测技术的发展是为了检测和隔离现代工业过程的异常情况,这些过程变得更加复杂,被归类为大规模系统。提出了几种用于多变量统计过程监测的故障检测和隔离指标。本文以田纳西州伊士曼化工过程为工业基准,对这些指标进行了讨论,并对其性能进行了比较。这些指标的效率通过4个关键性能指标(kpi)来衡量,即故障检测时延、虚警率、漏检率、正确故障隔离。

Fish diseases are the major cause for increasing mortality in fish farms. Automatic identification of diseased fish at early stages is necessary step to prevent spreading disease. Fish disease diagnosis suffers from some limitations that need high level of expertise to be resolved. Recognition of fish abnormal behaviors helps in early prediction of fish diseases. Fish behavior is evaluated by analyzing fish trajectories in videos. Abnormalities may be due to environmental changes. This paper introduces a survey on what computer vision techniques propose in that field. A comprehensive comparison between different automatic recognition systems is included. Finally, our approach is proposed to automatically recognize and identify three different types of fish diseases. These diseases are Epizootic ulcerative syndrome (EUS), Ichthyophthirius (Ich) and Columnaris. Our approach shows the effect of different color spaces on the Convolutional Neural Networkk CNN final performance.
鱼类疾病是养鱼场死亡率上升的主要原因。在早期阶段自动识别病鱼是防止疾病传播的必要步骤。鱼类疾病诊断存在一些局限性,需要高水平的专业知识才能解决。对鱼类异常行为的识别有助于鱼类疾病的早期预测。通过分析视频中鱼的运动轨迹来评估鱼的行为。异常可能是环境变化所致。本文介绍了计算机视觉技术在该领域的发展概况。对不同的自动识别系统进行了全面的比较。最后,我们提出了一种自动识别和识别三种不同类型鱼类疾病的方法。这些疾病是兽疫性溃疡综合征(EUS)、鱼鳞病(Ich)和柱状病。我们的方法显示了不同颜色空间对卷积神经网络CNN最终性能的影响。
