Augmented reality(AR) is a technology that covers virtual objects into a real environment with real objects for better observer’s knowledge. Virtual Reality (VR) enables user to interact with a computer-simulated environment which is either a simulation of the real world or an imaginary world. VR and AR are the key to explore, and touch the past, present and the future. They are the basis of creating one’s own world, one’s own custom-built reality. It enables users to design a video game to have a virtual stroll around the universe, to practice their own dream house, to experience a walk on an alien planet. We can learn by experiencing the most threatening and difficult situations by playing safe. Very few really know the basic principles of VR & AR and their open problems. In this survey, we present the historical overview of Virtual Reality and Augmented Reality, characteristics, and types of VR and AR systems. The requirements and challenges of typical VR and AR systems are illustrated.

A study to Understand Malware Behavior through Malware Analysis 通过恶意软件分析了解恶意软件行为的研究
Om Prakash Samantray, S. Tripathy, Susant Kumar Das
Most of the malware detection techniques use malware signatures for detection. It is easy to detect known malicious program in a system but the problem arises when the malware is unknown. Because, unknown malware cannot be detected by using available known malware signatures. Signature based detection techniques fails to detect unknown and zero-day attacks. A novel approach is required to represent malware features effectively to detect obfuscated, unknown, and mutated malware. This paper emphasizes malware behavior, characteristics and properties extracted by different analytic techniques and to decide whether to include them to create behavioral based malware signature. We have made an attempt to understand the malware behavior using a few openly available tools for malware analysis.
大多数恶意软件检测技术都使用恶意软件签名进行检测。检测系统中已知的恶意程序很容易,但当恶意软件未知时,问题就出现了。因为,未知的恶意软件无法通过使用可用的已知恶意软件签名来检测。基于签名的检测技术无法检测到未知攻击和零日攻击。需要一种新颖的方法来有效地表示恶意软件的特征,以检测混淆、未知和变异的恶意软件。本文重点讨论了利用不同分析技术提取的恶意软件行为、特征和属性,以及是否将其包含在基于行为的恶意软件签名中。我们已经尝试使用一些公开可用的恶意软件分析工具来理解恶意软件的行为。

High Gain DC-DC Converter Based on Hybrid Switched-Inductor Topology for PV Application 基于开关电感混合拓扑的高增益DC-DC变换器在光伏中的应用
Gagandeep Singh, S. Srivastava, Radhika Lalwani, Nilanjan Tewari, M. Prabhakar
In this paper a non-isolated high gain DC-DC converter which is preferred for photovoltaic (PV) applications is proposed. This converter uses hybrid switched inductor technique to enhance its overall voltage gain. The inductors of the gain extension network are all charged together in parallel and get discharged simultaneously in series to obtain the high voltage gain (>10). Resultantly, the voltage stress experienced by the switches of the proposed converter are reduced to 55% of the desired output voltage. An experimental prototype version of the proposed converter yields the rated voltage gain of 10.8 and delivers 21OW at a maximum efficiency of 94.45% when excited from an input voltage of 35 V. Further, the operating range of the converter is demonstrated by experimental results which are obtained for an output power ranging from 90% to 95% of rated power.

Anuja Patil, Pooja Balkrishna Dhuri, Prachi Kushe, Pratibha Ashok Mondkar, Suraj Acharekar
The proposed device automatically corrects the power factor without any human presence. It consists of a microcontroller which detects the power factor value, if the power factor goes below 0.9(lagging) during peak hours it automatically connects capacitor banks to improve it. Now a days, one APFC panel cannot be used for different application. To make it universal we provide four keys UP, DOWN, ENTER, MENU. These keys are used to enter the capacitor values and to vary the CT ratio. As the capacitor values and current magnitude varies according to the application. The main aim of the proposed model is to maintain the power factor nearer to 0.9 which helps to increase the efficiency of the system.

Single Stage Dual Boost Inverter with Half Cycle Modulation Scheme for PV System Applications 单级双升压逆变器与半周期调制方案的光伏系统应用
R. Priya, R. Valli, P. S. Santhana Krishnan
The objective of this paper is to develop a new voltage source inverter (VSI) that acts as a boost inverter. The proposed inverter topology will acts as inverter and also boosts the output voltage with respect to the applied input. In general, the output voltage (AC) of a conventional full-bridge inverter is lower than the input DC voltage. Boost inverters are used in systems, where the output AC voltage is required to be larger than the input DC voltage. In order to obtain output AC voltage higher than the input DC voltage, an additional step up chopper is usually required at the front end, bestowing a two-stage power conversion which yields increased circuit complexity. Hence, in this paper a Dual boost inverter (DBI) has been developed, as a single-stage converter with advantages of a small structure, reduced power devices, and good buck-boost ability. The conventional modulation strategy (full cycle modulation) of the proposed circuit makes all the switches to operate in high frequency and leads to high voltage/current stress, which in turn results in heavy conduction losses and switching losses. The proposed system uses Half Cycle modulation scheme which use the power switches in half cycle, and can greatly reduce the conduction and switching losses of the power devices. In addition, an improved DBI with two clamping switches is also proposed in this paper, to reduce the current circulation losses in DBI with low switching stress. Thus our proposed topology will achieve higher efficiency with reduced losses and switching stress. The simulation results are presented for DBI model and improved DBI model. An experimental prototype is also developed to realize the Dual boost inverter output (without clamping switches) to validate the simulation results.
本文的目标是开发一种新的电压源逆变器(VSI)作为升压逆变器。所提出的逆变器拓扑将作为逆变器,也提高输出电压相对于应用的输入。一般来说,传统全桥逆变器的输出电压(交流)低于输入直流电压。升压逆变器用于要求输出交流电压大于输入直流电压的系统中。为了获得比输入直流电压更高的输出交流电压,通常需要在前端增加一个额外的升压斩波器,从而实现两级功率转换,从而增加了电路的复杂性。因此,本文开发了一种双升压逆变器(DBI),它是一种单级变换器,具有结构小、器件功率小、升压能力强等优点。该电路的传统调制策略(全周期调制)使所有开关在高频率下工作,从而导致高电压/电流应力,从而导致严重的导通损耗和开关损耗。该系统采用半周期调制方案,使功率开关在半周期内工作,大大降低了功率器件的导通和开关损耗。此外,本文还提出了一种具有两个箝位开关的改进DBI,以降低开关应力,降低DBI中的电流循环损耗。因此,我们提出的拓扑结构将在减少损耗和开关应力的情况下实现更高的效率。给出了DBI模型和改进DBI模型的仿真结果。通过实验样机实现了双升压逆变器输出(无箝位开关),验证了仿真结果。

Four configurations of (a) steel (M19) material with stator and rotor and (b) composite material with stator and rotor (c) Laminated steel (M19) material for Stator and soft composite material (SMC) for Rotor and (d) soft composite material (SMC) for Stator and Laminated steel (M19) material for Rotor have been studied to obtain their nodal temperature distributions by using finite element analysis in different parts of stator and rotor frames. The study tells that the steel (M19) and Soft composite materials (SMC) based stator and rotor frame has a good thermal capability and it provides better feature in electrical vehicles. It mainly deals with the analysis of magnetic field, magnetic Flux distribution, and current density in the core.","PeriodicalId":363880,"journal":{"name":"2019 IEEE International Conference on System, Computation, Automation and Networking (ICSCAN)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123824340","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}

Security Analytics For Heterogeneous Web 异构Web的安全分析
R. Padmanaban, M. Thirumaran, V. Sanjana, A. Moshika
In recent days, Enterprises are expanding their business efficiently through web applications which has paved the way for building good consumer relationship with its customers. The major threat faced by these enterprises is their inability to provide secure environments as the web applications are prone to severe vulnerabilities. As a result of this, many security standards and tools have been evolving to handle the vulnerabilities. Though there are many vulnerability detection tools available in the present, they do not provide sufficient information on the attack. For the long-term functioning of an organization, data along with efficient analytics on the vulnerabilities is required to enhance its reliability. The proposed model thus aims to make use of Machine Learning with Analytics to solve the problem in hand. Hence, the sequence of the attack is detected through the pattern using PAA and further the detected vulnerabilities are classified using Machine Learning technique such as SVM. Probabilistic results are provided in order to obtain numerical data sets which could be used for obtaining a report on user and application behavior. Dynamic and Reconfigurable PAA with SVM Classifier is a challenging task to analyze the vulnerabilities and impact of these vulnerabilities in heterogeneous web environment. This will enhance the former processing by analysis of the origin and the pattern of the attack in a more effective manner. Hence, the proposed system is designed to perform detection of attacks. The system works on the mitigation and prevention as part of the attack prediction.
最近,企业正在通过web应用程序高效地扩展业务,这为与客户建立良好的消费者关系铺平了道路。这些企业面临的主要威胁是它们无法提供安全的环境,因为web应用程序容易出现严重的漏洞。因此,许多安全标准和工具一直在发展以处理这些漏洞。虽然目前有许多可用的漏洞检测工具,但它们不能提供有关攻击的足够信息。对于组织的长期运作,需要数据以及对漏洞的有效分析来增强其可靠性。因此,提出的模型旨在利用机器学习和分析来解决手头的问题。因此,通过PAA模式检测攻击序列,并进一步使用SVM等机器学习技术对检测到的漏洞进行分类。提供了概率结果,以便获得可用于获取用户和应用程序行为报告的数值数据集。基于支持向量机分类器的动态可重构PAA是一项具有挑战性的任务,需要对异构web环境下的漏洞及其影响进行分析。这将通过更有效地分析攻击的来源和模式来增强前一种处理。因此,所提出的系统被设计为执行攻击检测。该系统将缓解和预防作为攻击预测的一部分。
