Software reuse is a very effective strategy for software industry to develop high quality software. To use software reusable components from the reuse repository, the selection of proper retrieval technique is very essential. The selection of best component or optimal selection from retrieved components is much more difficult than simple retrieval. This paper presents classification and retrieval of software reusable components by using integrated classification and also the selection of best component by using rank of the component. The retrieval of an optimal relevant component is one of the key issues considered in the proposed work. Finally experiments demonstrate results for displaying most relevant software reusable components with calculated grade.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108507","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 method uses a combination of various features derived from multichannel EEG signals. Features are extracted from a 4 second window to create a feature vector. Classifier (SVM/ANN) is trained using feature vectors from a carefully chosen training set. Feature vectors from a new data set when fed to the trained models will give an output which is then processed using different rules to remove interictal spikes and correctly detect the seizure regions. Results of applying this on long term EEG recordings of 27 epileptic patients revealed that, the proposed method is capable of very high degree of discrimination between the interictal region and ictal(seizure) region. The proposed method is a generalized seizure detection method which is not patient specific and has an average detection accuracy of nearly 75%.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130913203","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}

An edge driven device computes by setting inputs on one edge of the device, driving the entire system into a global ground state, and reading the results on the far edge. In the proposed architecture, the device is made up of an array of nickel dots and offers low power dissipation, high integration density, room temperature operation and simple fabrication steps. Current traveling down a nearby wire is used to set the magnetic polarity of dots on the input edge. The logical state of a dot is identified with the orientation of the dots magnetic field. The switching of polarity was attempted via a locally induced magnetic field generated by reversing the direction of the current in the nearby wire, a first step in the ultimate construction of an edge-driven device. The aluminum wire had dimensions of 250 nm in thickness, 8 μm in width, and 40 μm in length. The nickel dots, formed by electron beam lithography, had a thickness of 100 nm and diameter ranging from 300 nm to 500 nm. Switching of the magnetic polarity of dots near the wire was observed using magnetic force microscopy (MFM), with MFM cantilever phase images used to identify the reversals. In contrast, dots further away from the wire did not appear to be influenced by the direction of current in the wire, another requirement for edge-driven devices.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"601 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123195290","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}

There are various routing protocols developed for communication in a MANET. Owing to the basic characteristics of MANETs, designing an efficient and secure routing protocol is a daunting task. Ad hoc On Demand Distance Vector Routing Protocol (AODV) is one of the widely researched on-demand routing protocol for use in MANETs. But it is highly vulnerable to attacks as it doesn't have any security mechanism. In this paper, we study, security Issues, malicious node activity in AODV under different scenarios, network size, traffic load, and mobility which affect packet delivery ratio, reliability, throughput and end to end delay in MANETs to study the performance of this routing protocol.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123396145","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 substantially reduced leakage current leads to a high ON/OFF Current ratio. The transconductance of the device is found to be 6e-4S/μm at a gate voltage of 0.5 V. The rise in ON current is mainly due to the increase in the accumulation of the positive charges at the Si3N4/GaN interface which leads to the increase in the sheet carrier concentration in the 2DEG channel.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125777277","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}

The flux and instantaneous reactive power based sensorless speed estimation algorithms are designed and analyzed. In the flux based speed estimation algorithm, the estimated speed can be obtained directly from the flux and current relations. Mainly the speed error occurs between the estimated and the actual speed because of the errors in measurement of the motor parameters and the sensing errors of the line currents and input voltages. To minimize the speed error, the estimated speed error is compensated by the instantaneous reactive power. The reactive power based estimation algorithm improves the performance of the drive system by avoiding integrator's drift problem compared to flux estimation algorithm. The algorithms was verified by simulation in MATLAB /SIMULINK using SVPWM inverter.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125142480","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 strong designated verifiable group signature scheme","authors":"S. Mohanty, B. Majhi, V. Iyer","doi":"10.1109/IMAC4S.2013.6526468","DOIUrl":"https://doi.org/10.1109/IMAC4S.2013.6526468","url":null,"abstract":"This paper presents a strong designated verifier group signature scheme, in which signature is generated by any member of the group and it is verified by only a specific receiver, called a designated verifier using the public parameters of the group and his own secret key. The verifier assumes that the signature indeed is from the group itself, not from any individual group member. In this scheme, anonymity of the signer is completely preserved. The verifier cannot link a signature to the signer. The scheme is secure as an adversary cannot verify the signature even if the secret key of the signer is compromised or leaked. Also, neither the group manager nor any member of the group can produce a valid signature on behalf of another member. Only in case of legal disputes, the group manager can disclose the identity of a group member who has signed a document. The major benefit of this scheme is that the length of the group signature is independent of number of group members and it remains unaffected if some members left the group or new members join the group. Security of the proposed scheme lies in the complexity of solving three computationally hard problems, namely, Computational Diffiee-Helmann (CDH) problem, Discrete Logarithm Problem (DLP) and Integer Factorization Problem (IFP). This scheme can be useful in organizations where there is a need to send confidential documents to a specific recipient. This scheme can also be applicable to real life scenarios, such as, e-commerce applications, e-banking and e-voting.","PeriodicalId":403064,"journal":{"name":"2013 International Mutli-Conference on Automation, Computing, Communication, Control and Compressed Sensing (iMac4s)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121807699","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}
