In this approach, the request transmits the password in plaintext and thus, it is not recommended due to security reasons. In this article, we proposed a mobile phone-based authentication with session key agreement approach that provides strong authentication services to SOCKS V5 protocol. The protocol is suitable for mobile users and makes use of International Mobile Subscriber Identity (IMSI) to provide unique identification. In this protocol, mobile phone is used to provide authentication between user and SOCKS proxy server when a user wants to access a Virtual Private Network (VPN). Easy availability and widely acceptance of mobile phones in comparison to smart cards is the motivation behind developing this authentication protocol. The proposed protocol establishes the session keys between mobile user and SOCKS proxy server as well as Application Server of the VPN. In the proposed protocol, multiple mobile users can simultaneously access the application server via a SOCKS proxy server. The proposed protocol is secure against known attacks.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114690432","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}

Being autonomous in nature, UGATVs are capable of operating over a wide variety of terrain, operating condition. Hence robust and precise control of UGATV is required. For developing a robust control strategy it is necessary to have an accurate mathematical model of UGATV. In this paper, nonlinear mathematical model of UGATV for straight and turning motion is presented and is implemented in MATLAB environment with various subsystems. Thereafter transfer function model of UGATV is obtained by linearizing. Using this linearized transfer function model conventional proportional integral derivative (PID) controller are designed and applied to nonlinear model of UGATV. Simulation results are generated for various transient conditions and disturbance levels.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"01 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130570614","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}

In such environments, the dynamic availability of resources can affect execution of parallel applications. Parallel applications modelled by Directed Acyclic Graphs (DAG) scheduled on a network of heterogeneous processors so as to minimize finish time is a known NP complete problem. The Heterogeneous Earliest Finish Time (HEFT) is a static task scheduling algorithm that assumes probability of resource availability is 100% whereas in real life situations the case is not true. The temporal availability of resources is to be considered in task scheduling decisions. We propose a new Probabilistic Availability based Task Scheduling Algorithm (PATSA) where tasks are scheduled not only based on earliest finish time of task but also on resource availability probability so as to minimize makespan. Our algorithm was compared with existing HEFT algorithm for a certain set of random DAGs based on performance metrics such as Makespan, Schedule Length Ratio and Speedup.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131828822","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}

Analog circuits need to often be handcrafted as opposed to software and digital design which can simply be recompiled following a change of parameters. Further, minor changes in design parameters can have unexpected outcomes on system performance, due to which manual design space exploration can be difficult except for most non-trivial analog circuit configurations. In this paper we explore different methods for numerical optimization based tools which are available to automate analog design so that the design in a pseudo sense can simply be recompiled following some changes. We explore genetic algorithms, geometric optimization as well as finding the minimum of constrained nonlinear multivariable functions. The findings provide guidelines to Op-Amp designers looking to automate the parameter selection process.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134019841","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}

In this research work, a high performance planar phased-array antenna has been designed using an 8×8 square grid of z-controlled antenna monopoles with a length of 0.482λ. The considered element spacing is 0.315λ and the average directivity of 22.0 dBi. The uniform current distributions and binomial current distribution has been used for the design. To minimize the side lobe level characteristic to a lower one of -20 dB with reference to the main beam, the binomial current distribution is preferred for the work. This approach for the synthesis of antenna's beam pattern reduces multiple interferences by installing nulls in the course of signals interference and putting the central beam pattern in the track of the targeted signals in phase and amplitude regulation.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114304001","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}

{"title":"A framework for the estimation of OO software reliability using design complexity metrics","authors":"R. Bharathi, R. Selvarani","doi":"10.1109/ITACT.2015.7492648","DOIUrl":"https://doi.org/10.1109/ITACT.2015.7492648","url":null,"abstract":"Reliability of a software product essentially denotes its trustworthiness or dependability. The stakeholder's requirement is normally a robust and highly reliable software product. Reliability is one of the dynamic characteristics of software, which can be quantitatively measured by analyzing the failure data. In order to estimate as well as to predict the reliability of software systems, failure data need to be properly measured by various means during software development. Most of the software failures happen due to poor design quality. Controlled and well-monitored design with respect to reliability can be achieved by quantitative analysis and appropriate mapping of design metrics. This analysis leads to the prediction of reliability at the design stage of Software Development Life Cycle (SDLC) of Object Oriented (OO) software, which will provide early information for software architect about the quality of the design with respect to reliability. Chidamber and Kemerer (CK) design metrics play a dynamic role to understand the design aspects of object-oriented software. In this context, we have proposed a framework for predicting reliability at the design phase of software development life cycle. Through empirical analysis, a valid hypothesis is established relating the design complexity metrics and reliability. A functional relationship is established through polynomial regression technique for selected design metrics. With these equations, an estimation model called R-MODEL is formulated through weighted linear combination of multifunctional parameters, which predicts reliability for any module of the OO software project. The R-MODEL is evaluated and validated with commercial software, which is found to be satisfactory. This quantitative empirical analysis provides an idea for the percentage influence of design metrics on reliability at the design level. The approach is to make, measurement as an integral part of the software design process to assist software designer to predict the software reliability at early stage and to improve the product quality.","PeriodicalId":336783,"journal":{"name":"2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123629173","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}
