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。

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.

This paper presents Nonintrusive Load Monitoring (NILM) for electrical home appliances network which consists of a known set of devices. Hidden Markov Model (HMM) is used for system modeling. The proposed method enhances determining and defining all states for each device. First we classify each device states into a set of states not only the ON and OFF states in the form of variations in its active power ranges. AMPDS collected dataset is used in training and testing for six selected home devices in a certain household and is also compared to GREEND dataset showing the advantage of the variable observed power readings with those of constant power readings. Each device has different number of states. Then the proposed mechanism is used to minimize these states after understanding the behavior of each state into OFF and ON states only. This method provides high accuracy on the system level, the device level, state inference, power and state sequence estimation.
本文提出了一种针对由一组已知设备组成的家电网络的非侵入式负荷监测方法。隐马尔可夫模型(HMM)用于系统建模。提出的方法增强了对每个设备的所有状态的确定和定义。首先,我们将每个器件的状态分为一组状态,而不仅仅是其有功功率范围变化形式的ON和OFF状态。AMPDS收集的数据集用于特定家庭中六个选定的家用设备的训练和测试,并与GREEND数据集进行了比较,显示了变量观测功率读数与恒定功率读数的优势。每个设备都有不同数量的状态。然后,在了解每个状态的行为后,使用所建议的机制将这些状态最小化,使其仅为OFF和ON状态。该方法在系统级、器件级、状态推断、功率和状态序列估计等方面具有较高的精度。

This paper presents an extensive study of the different ways the Internet of Things (IoT) applications exploit the recently developed blockchain technology. Even though the blockchain technology was originally presented as a security mechanism, its numerous benefits such as decentralization, immutability, persistence, anonymity and auditability can be used by IoT systems in different ways. More specifically, we classify the ways IoT systems exploit blockchain into three categories: resource management, decentralized information sharing, and IoT security. The comprehensive study of the applications of the blockchain technology in the different IoT domains presented in this paper sheds the light on the future research directions in the integration of the two technologies.

Due to the vast developments in the media communication field and the quality of the visual imaging, image data compression has been one of the most interesting field. The main purpose of the image compression is to produce a very low bit rate while achieving a high quality of the reconstructed images. Image compression are used for all fields of media communication such as medical image recognition, multimedia, digital image processing. There are different algorithms for compression and reconstruction. One of these methods is the Orthogonal Matching Pursuit that is used mainly in the reconstruction of the radar signal. This paper discloses a new methodology for image compression and reconstruction to enhance the performance while at the same time reducing the bit data size. This kind of reconstruction algorithm is based upon multistage compression and OMP reconstruction. The Matlab Simulation and the FPGA implementation will be provided in this paper to validate the concept of this paper.

Power transformer is an essential part in any power plant, so continuous check of its reliability should be kept up. Dissolved Gas Analysis (DGA) is one of the most important techniques for detecting incipient faults of transformer that immersed in insulation oil. Some widely used conventional techniques based on DGA such as Roger's and IEC methods were developed to diagnose faults of power transformers. These methods succeeded noticeably to detect transformer's faults. However, they fail to detect the fault type if the measured ratios of gases slightly deviated from the crisp boundaries of ranges assigned by these methods. An Artificial Intelligent technique based method called fuzzy logic approach, which is the field of study in this paper is used to overcome the above mentioned drawback by fuzzifying the boundaries of ranges defined by these techniques. This paper presents a comparison between the results of conventional Roger's, IEC methods and the proposed fuzzy logic.
电力变压器是电厂的重要组成部分,必须对其可靠性进行持续检查。溶解气体分析(DGA)是检测浸在绝缘油中的变压器早期故障的重要技术之一。基于DGA的罗杰法和IEC法等常用的常规方法被用于电力变压器的故障诊断。这些方法在变压器故障检测中取得了显著的成功。但是,如果测量到的气体比率稍微偏离这些方法所确定的范围的清晰边界,它们就不能检测到断层类型。本文研究的领域是一种基于人工智能技术的模糊逻辑方法,通过模糊化这些技术所定义的范围的边界来克服上述缺点。本文将传统的罗杰方法、IEC方法与所提出的模糊逻辑的结果进行了比较。

Solving the traffic congestion problem has many benefits financially and environmentally. The application of Artificial Intelligence to solving the traffic congestion problem has been going on for a while. However, most of the current research in this area depends on knowing lots of information about all vehicles in the network. While it produces promising results, applying these techniques in the current world is not easy. In this paper, we apply reinforcement learning to the field of traffic control under the assumption that only minimal information is available. Our approach produces results that are better than currently deployed fixed-time traffic lights without having heavy requirements. In our first test configuration, our agent's waiting time is 82.3% of the best fixed-time traffic lights' waiting time and the average CO2 emissions produced by our agent is 97.5% of the emissions produced by the best fixed-time traffic lights. This shows the potential of applying reinforcement learning to the traffic control problem with limited state.

Abstractive text summarization is the task of generating a novel summary given an article, not by merely extracting and selecting text to produce a summary, but by actually creating and understating the given text to produce a summary. LSTM seq2seq encoder-decoder with attention models have proved successful in this task, but they suffer from some problems. In this work, we would go through multiple models to try and solve these problems, beginning with simple seq2seq with attention models to going to Pointer-Generator, to using a curriculum learning approach called Scheduled-Sampling, till we reach the new approaches of combining reinforcement learning with seq2seq. We have applied these models on multiple datasets for multiple languages, English and Arabic. We have also introduced a new novel method of working with agglutinative languages, it is a preprocessing technique that is applied to the dataset which increases the relevancy of the vocabulary, which effectively increases the efficiency of the text summarization without modifying the models, we call this technique advanced cleaning, we have applied it to the Arabic dataset, and it can then be applied to any other agglutinative language. We have built these models in Jupiter notebooks to run seamlessly on Google colaboratory.11https://medium.com/@theamrzaki22https://github.com/theamrzaki/text_summurization_abstractive_methods
抽象文本摘要是为给定的文章生成新颖摘要的任务,不是仅仅通过提取和选择文本来生成摘要,而是通过实际创建和理解给定的文本来生成摘要。基于注意力模型的LSTM seq2seq编码器在此任务中取得了成功,但存在一些问题。在这项工作中,我们将通过多个模型来尝试解决这些问题,从带有注意力模型的简单seq2seq开始,到使用指针生成器,再到使用称为调度采样的课程学习方法,直到我们达到将强化学习与seq2seq相结合的新方法。我们已经将这些模型应用于多种语言(英语和阿拉伯语)的多个数据集。我们还引入了一种新的处理黏着语言的方法,它是一种应用于数据集的预处理技术,它增加了词汇的相关性,在不修改模型的情况下有效地提高了文本摘要的效率,我们称这种技术为高级清洗,我们已经将其应用于阿拉伯语数据集,然后它可以应用于任何其他黏着语言。我们已经在Jupiter笔记本电脑中构建了这些模型,以便在谷歌collaborabory.11https://medium.com/@theamrzaki22https://github.com/theamrzaki/text_summurization_abstractive_methods上无缝运行

We have also introduced a new novel method of working with agglutinative languages, it is a preprocessing technique that is applied to the dataset which increases the relevancy of the vocabulary, which effectively increases the efficiency of the text summarization without modifying the models, we call this technique advanced cleaning, we have applied it to the Arabic dataset, and it can then be applied to any other agglutinative language. We have built these models in Jupiter notebooks to run seamlessly on Google colaboratory.11https://medium.com/@theamrzaki22https://github.com/theamrzaki/text_summurization_abstractive_methods","PeriodicalId":136643,"journal":{"name":"2019 14th International Conference on Computer Engineering and Systems (ICCES)","volume":"223 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":"131546681","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}

This research focuses on using quantifiable methods for using the IoT as a main support to firefighting/intruder detection. From our research, we have found numerous researches associated to supplying remote services by means of portable sensors and communication technologies. We represent in our research a unique Smart Firefighting/lntruder Detection System with the support of Fuzzy Logic Decision Control (FIDFUZ). The projected system has an innovative value which is the Fuzzy Logic Decision Support System application that deals with the predicted inaccuracy and the doubt in the sensor's information acquired, as well as minimizing the rate of false positive and true negative. FIDFUZ full architecture is presented, applied and checked by simulation and using real data.
