M. Vinoth, R. Vallikannu
Different RMPA architectures are proposed in this paper to realize an antenna to operate in sub-6 GHz for 5G communications. The antenna design is optimized in steps to achieve a compact antenna with high performance. A basic Rectangular Patch Antenna (RPA) structure is initially presented, which operates in 3.13 GHz. The initial structure is examined and optimized by adding a Metamaterial (MTM) ground. The modified RPA with MTM ground exhibits resonance at 3.27 GHz, 3.78 GHz and 3.92 GHz. RPA structure is again tuned by adding three slots at top right edge of antenna patch and a Triple Slotted Rectangular Microstrip Patch Antenna (TSRMPA) with MTM ground is finally realized. The presented antenna is tuned to operate at sub-6 GHz by modifying the structure without altering the dimension. The TSRMPA with MTM ground resonates at 3.5 GHz with good return loss performance of -30.77 dB and gain of 5 dB. The dimension of compact TSRMPA with MTM ground is 30.2 x 36.4 mm2. These antennas are investigated using High Frequency Structural Simulator (HFSS) software. Finally, good concurrence between simulated and tested result is presented to prove the functioning of proposed antenna design.
本文提出了不同的RMPA架构,以实现5G通信中工作在6ghz以下的天线。天线设计是逐步优化的,以实现紧凑的高性能天线。初步提出了一种工作频率为3.13 GHz的基本矩形贴片天线(RPA)结构。通过添加超材料(MTM)地基对初始结构进行了检测和优化。采用MTM接地的改进RPA在3.27 GHz、3.78 GHz和3.92 GHz处表现出谐振特性。通过在天线贴片的右上边缘增加三个槽,对RPA结构进行再次调谐,最终实现了MTM接地的三槽矩形微带贴片天线(TSRMPA)。在不改变天线尺寸的前提下,通过改变天线的结构,将天线调谐到6ghz以下。采用MTM接地的TSRMPA谐振频率为3.5 GHz,回波损耗性能为-30.77 dB,增益为5 dB。带MTM接地的紧凑型TSRMPA尺寸为30.2 x 36.4 mm2。利用高频结构模拟器(HFSS)软件对这些天线进行了研究。最后,仿真结果与实验结果吻合良好,验证了所提天线设计的有效性。

Detection of Recoloring and Copy-Move Forgery in Digital Images 数字图像重着色和复制-移动伪造的检测
Jijina M.T, Litty Koshy, Gayathry.S. Warrier
Due to the availability of numerous image manipulation tools, fraud images can be generated very easily and effectively. These fraud images are quite difficult to recognize. A section of the image is copied and pasted at some other location on the same image in copy-move forgery to drop meaningful objects or to bring additional information which is not present actually in the image. Whereas, the image recoloring techniques normally change the images via a variety of mechanisms like contrast enhancement and colorization. In the proposed method, copy move forgery detection is based on similarities in the images and finding the forged part by using threshold and contouring techniques. Recolored image detection uses a convolution neural network with three layers which outputs the probability of recoloring. As the techniques for image forging are developing faster, the necessity of highly efficient and accurate image forgery detection also increases. Here, this proposed system focuses on both recoloring and copy-move forgery detection.
由于许多图像处理工具的可用性,可以非常容易和有效地生成欺诈图像。这些欺诈图像很难识别。在复制-移动伪造中,将图像的一部分复制并粘贴到同一图像的其他位置,以删除有意义的对象或带来实际不存在于图像中的附加信息。然而,图像再着色技术通常通过对比度增强和着色等各种机制来改变图像。在该方法中,复制移动伪造检测是基于图像的相似性,并利用阈值和轮廓技术找到伪造部分。重着色图像检测采用三层卷积神经网络输出重着色概率。随着图像伪造技术的快速发展,高效、准确的图像伪造检测的必要性也随之增加。在这里,该系统的重点是重新着色和复制移动伪造检测。

Twitter Hate Speech Detection using Stacked Weighted Ensemble (SWE) Model 基于堆叠加权集成(SWE)模型的Twitter仇恨语音检测
Sujatha Arun Kokatnoor, Balachandran Krishnan
Online Social Media has expanded the freedom of expression in the internet, which has become a disturbing problem if it has an impact on the situation or the interest of a country. Hate speech refers to the use of hostile, abusive or offensive language, directed at a certain group of people who share common property, whether it is their gender, ethnicity or race (i.e. racism), faith and religion. Therefore, auto detection of hate speeches has an increased importance in Online Social Media for filtering any message that has hatred language before posting it to the network. In this paper, a Stacked Weighted Ensemble (SWE) model is proposed for the detection of hate speeches. The model ensembles five standalone classifiers: Linear Regression, Naïve Bayes’, Random Forest, Hard Voting and Soft Voting. The experimental results on a Twitter® dataset has shown an accuracy of 95.54% in binary classification of tweets into hateful speech and an improved performance is noted compared to the standalone classifiers.
网络社交媒体扩大了互联网上的言论自由,如果影响到一个国家的局势或利益,这将成为一个令人不安的问题。仇恨言论是指使用敌对的、辱骂性的或攻击性的语言,针对拥有共同财产的某一群体,无论其性别、民族或种族(即种族主义)、信仰和宗教。因此,仇恨言论的自动检测在在线社交媒体中越来越重要,因为它可以在发布到网络之前过滤任何含有仇恨语言的信息。本文提出了一种用于仇恨言论检测的堆叠加权集成(SWE)模型。该模型集成了五个独立分类器:线性回归,Naïve贝叶斯,随机森林,硬投票和软投票。在Twitter®数据集上的实验结果显示,将推文分类为仇恨言论的二元分类准确率为95.54%,与独立分类器相比,性能有所提高。

GALB: Load Balancing Algorithm for CP-ABE Encryption Tasks in E-Health Environment 电子卫生环境中CP-ABE加密任务的负载均衡算法
M. Taha, Rasel Chowdhury
Security of personal data in the e-healthcare has always been challenging issue. The embedded and wearable devices used to collect these personal and critical data of the patients and users are sensitive in nature. Attribute-Based Encryption is believed to provide access control along with data security for distributed data among multiple parties. These resources limited devices do have the capabilities to secure the data while sending to the cloud but instead it increases the overhead and latency of running the encryption algorithm. On the top of if confidentiality is required, which will add more latency. In order to reduce latency and overhead, we propose a new load balancing algorithm that will distribute the data to nearby devices with available resources to encrypt the data and send it to the cloud. In this article, we are proposing a load balancing algorithm for EHealth system called (GALB). Our algorithm is based on Genetic Algorithm (GA). Our algorithm (GALB) distribute the tasks that received to the main gateway between the devices on E-health environment. The distribution strategy is based on the available resources in the devices, the distance between the gateway and the those devices, and the complexity of the task (size) and CP-ABE encryption policy length. In order to evaluate our algorithm performance, we compare the near optimal solution proposed by GALB with the optimal solution proposed by LP.
电子医疗中的个人数据安全一直是一个具有挑战性的问题。用于收集患者和用户的这些个人和关键数据的嵌入式和可穿戴设备本质上是敏感的。基于属性的加密被认为为多方之间的分布式数据提供访问控制和数据安全性。这些资源有限的设备在将数据发送到云时确实具有保护数据的功能,但它反而增加了运行加密算法的开销和延迟。最重要的是,如果需要保密,这将增加更多的延迟。为了减少延迟和开销,我们提出了一种新的负载平衡算法,该算法将数据分发到附近具有可用资源的设备上,以加密数据并将其发送到云。在本文中,我们提出了一种用于电子健康系统的负载平衡算法(GALB)。该算法基于遗传算法(GA)。我们的算法(GALB)将接收到的任务在电子健康环境中的设备之间分配到主网关。分发策略基于设备中的可用资源、网关与这些设备之间的距离、任务的复杂性(大小)和CP-ABE加密策略长度。为了评估算法的性能,我们比较了GALB算法和LP算法的近最优解。

A Comparative Assessment of Cascaded Double Voltage Lift Boost Converter 级联双电压升压变换器的比较评价
S. Radhika, V. Margaret
In several power conversion applications, dc-dc boost converters with voltage boost techniques are extensively used in order to meet the growing power demand. The main drawback of conventional dc-dc boost converter is obtaining high DC voltages, when operated at high duty ratio which causes switching losses and decreases overall efficiency because of the switch being used to be in ‘ON’ state for long time and voltage stresses across switch increases. The main objective of proposed converter is to obtain high voltage without extreme duty ratio. When input voltage of 15V DC is given, 201.1V DC output voltage is attained at duty ratio of 0.4 by the cascaded double voltage lift boost converter. To validate the performance of proposed converter, simulation is carried out in LTspice XVII and a comparative assessment of proposed converter with other converters at different duty ratio are realized.
在许多功率转换应用中,采用升压技术的dc-dc升压转换器被广泛使用,以满足日益增长的功率需求。传统的DC - DC升压变换器的主要缺点是在高占空比下工作时,由于开关长时间处于“ON”状态,导致开关损耗和整体效率降低,并且开关间的电压应力增加。该变换器的主要目标是获得无极端占空比的高电压。当输入电压为15V时,级联双升压变换器在占空比为0.4的情况下可获得201.1V的直流输出电压。为了验证变换器的性能,在LTspice XVII中进行了仿真,并与其他变换器在不同占空比下进行了比较评估。

Sonjoy Rana, Shounak Sengupta, Sourav Jana, Rahul Dan, Mahamuda Sultana, D. Sengupta
Traffic accidents contribute to an annual death toll of 1.25 million marking one of the primary causes of fatality. The Post Accident Response for such an alarming Figure calls for an immediate and effective Emergency Care which takes into account a series of time critical procedures beginning with the activation of the Quick Accident Response System (QARS) proposed in this communication. The implementation of Internet of Things (IoT) in QARS helps to detect an accident using multi-functional accelerometer and ultrasonic/proximity sensors. The video recording of the accident along with the exact location of the accident site fetched using a GPS-GSM module, along with the driver details will be immediately notified via internet to the nearest Emergency Response Units (ERU) through the Emergency Services portal of a dedicated mobile application. Pedestrians can also use the Pedestrian portal in the application to send live image and video feed to the Emergency services. An offline feature, allows sending accident alert and exact accident location to the nearest ERUs/pre-saved emergency contact numbers in the form of a simple text message. The work in this paper provides an automated system for emergency support in case of accidents.

Transparent Data Encryption: Comparative Analysis and Performance Evaluation of Oracle Databases 透明数据加密:Oracle数据库的比较分析与性能评价
K. Natarajan, Vaheedbasha Shaik
This Transparent Data Encryption (TDE) can provide enormous benefits to the Relational Databases in the aspects of Data Security, Cryptographic Encryption, and Compliances. For every transaction, the stored data must be decrypted before applying the updates as well as should be encrypted before permanently storing back at the storage level. By adding this extra functionality to the database, the general thinking denotes that the Database (DB) going to hit some performance overhead at the CPU and storage level. However, The Oracle Corporation has adversely claimed that their latest Oracle DB version 19c TDE feature can provide significant improvement in the optimization of CPU and no overhead at the storage level for data processing. Impressively, it is true. the results of this paper prove too. Most interestingly the results also revealed about highly impacted components in the servers which are not yet disclosed in any of the previous research work. This paper completely concentrates on CPU, IO, and RAM performance analysis and identifying the bottlenecks along with possible solutions.
这种透明数据加密(TDE)可以在数据安全性、加密加密和遵从性方面为关系数据库提供巨大的好处。对于每个事务,在应用更新之前必须对存储的数据进行解密,并且在永久存储回存储层之前应该对数据进行加密。通过向数据库添加这种额外的功能,一般认为数据库(DB)将在CPU和存储级别上产生一些性能开销。然而,Oracle公司反驳说,他们最新的Oracle DB版本19c TDE特性可以在CPU优化方面提供显著的改进,并且在数据处理的存储级别上没有开销。令人印象深刻的是,这是真的。本文的结果也证明了这一点。最有趣的是,结果还揭示了服务器中高度受影响的组件,这些组件在之前的任何研究工作中都没有披露。本文完全集中于CPU、IO和RAM性能分析,并确定瓶颈以及可能的解决方案。

Resiliency Analysis of ONOS and Opendaylight SDN Controllers Against Switch and Link Failures ONOS和Opendaylight SDN控制器对交换机和链路故障的弹性分析
M. Dagli, Selcuk Keskin, Yagmur Yigit, Adem Kose
Video conference applications require a high quality of service (QoS) from the point of latency, jitter, and bandwidth. As the QoS parameters seriously suffer from instant congestions and network failures, resiliency mechanisms utilized at network level have a direct impact on the experienced video quality. In addition to the solutions offered under traditional networking, software defined networking (SDN) paradigm also offers various solutions to keep quality of experience (QoE) at certain levels even in instant network failure situations. Different types of SDN controllers provide different resiliency mechanisms to recover from failures. Recovery time is an important parameter to keep video conference experience at satisfactory levels as longer recovery time causes frozen streams, streaming delays and even drops in video conferencing. This study gives a comparative analysis of the recovery time on ONOS and Opendaylight SDN controllers in case of the link and switch failures.
视频会议应用从时延、抖动、带宽等方面要求高的QoS (quality service)。由于QoS参数严重受到即时拥塞和网络故障的影响,因此在网络层面采用的弹性机制直接影响到体验到的视频质量。除了传统组网下提供的解决方案外,软件定义网络(SDN)范式还提供了各种解决方案,即使在即时网络故障的情况下也能保持一定水平的体验质量(QoE)。不同类型的SDN控制器提供不同的弹性机制来从故障中恢复。恢复时间是保证视频会议体验满意的重要参数,较长的恢复时间会导致视频会议流冻结、流延迟甚至下降。本研究对比分析了ONOS和Opendaylight SDN控制器在链路和交换机故障情况下的恢复时间。

As the QoS parameters seriously suffer from instant congestions and network failures, resiliency mechanisms utilized at network level have a direct impact on the experienced video quality. In addition to the solutions offered under traditional networking, software defined networking (SDN) paradigm also offers various solutions to keep quality of experience (QoE) at certain levels even in instant network failure situations. Different types of SDN controllers provide different resiliency mechanisms to recover from failures. Recovery time is an important parameter to keep video conference experience at satisfactory levels as longer recovery time causes frozen streams, streaming delays and even drops in video conferencing. This study gives a comparative analysis of the recovery time on ONOS and Opendaylight SDN controllers in case of the link and switch failures.","PeriodicalId":138966,"journal":{"name":"2020 Fifth International Conference on Research in Computational Intelligence and Communication Networks (ICRCICN)","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115734351","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}

OBSC:Osmotic BlockChain based framework for Smart City Environment OBSC:基于区块链的智能城市环境框架
Sourav Hati, D. De
Osmotic computing gives a novel worldview in brilliant city design. Numerous analysts have performed to create and to made sure about shrewd city engineering of the internet of-things (IoT) worldview. Security is the fundamental worry of the present exploration. In this situation, BlockChain starts in the time of the IoT worldview. In this proposed work, the creators concentrate on the information security, administration inertness and force utilization of the framework. The proposed feasible smart city technology has ordered into three unique levels, for example, physical level, edge level, and cloud level. Where the edge level is acquainted with the neighborhood BlockChain application and the cloud is utilized for worldwide and computational reason. BlockChain application is structured on the Amazon web administrations interface. The smart city engineering is ready to lessen error just as force utilization is diminished utilizing BlockChain applications. AWS CloudWatch observing apparatus and it additionally shows the status of the worldwide BlockChain database.
