In this paper, we present an algorithm to classify single-trial electroencephalogram (EEG) during the preparation of self-paced key tapping based on common spatial subspace decomposition (CSSD). Resulting 28 features for a trial from CSSD are classified using three classifiers (1) linear discriminant analysis, (2) quadratic discriminant analysis and (3) support vector machine. For two class problem, linear subspaces are estimated using CSSD analysis that maximizes the variance of the signal for one class while minimizes the variance of the other. Improvement in the proposed work includes reduction in the number of features to 28 only that result in a significant decrease in computational complexity while improving the accuracy of classification from earlier reported 86% to 88% using data set IV of BCI Competition 2003.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"54 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131836079","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}

A transmission line based coupled model of interconnect is used for analysis. Peaks and delays at far-end of victim line are estimated for the conditions when the inputs to two coupled interconnects are switching in-phase and out-of-phase. Waveforms are analyzed in general with homogeneous and non-homogeneous drivers for unipolar inputs. Alpha Power Law model of MOS-transistor is used to represent the transistors in CMOS-driver. The comparison of analytically obtained results with SPICE simulations show that the proposed model captures noise peak and their timing; 90% propagation delay; transition time delay and waveform shape with good accuracy.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"42 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121004416","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 first phase preprocesses the faces with bin-based histogram approach and extracts the preliminary results which are rotation invariant in nature. The second phase verifies the face patterns with POC- based matching technique in order to obtain the exact results which are the same not only distribution-wise but also content- wise. Time effective preprocessing by bin-based histogram approach filters out the mismatches and helps in reduction of the overall complexity of POC. The empirical results obtained on ORL database shows the recognition accuracy of 99.5%, which is very promising and is comparable with any other face recognition scheme.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114380818","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 paper presents and evaluates a novel scheme called \"QoS aware Inter Piconet Scheduling in Scatternet (QIPS) \" tailored for interpiconet scheduling in small-scale scatternets and use hold mode. In QIPS, to provide the QoS, we divide the incoming traffic i-e best effort, audio and video data in to eight traffic classes on the basis of their QoS (delay and bandwidth) requirements. According to their QoS requirements different priorities are assigned to these traffic classes and phenomenon of packet forwarding and switching of the bridge node are dictated by these priorities. Using that QIPS provides an integrated solution for both intra and interpiconet scheduling, i.e., for polling of slaves and scheduling of bridge. It supports both delay and bandwidth guarantees according to the QoS requirement of the traffic classes and also aims to remain fair and efficient with asymmetric flow rates and also QIPs use low-power hold mode, which allows greater flexibility than other low- power modes. We have evaluated the performance of proposed algorithm by comparing with LLA [8] and EFSA [9] regarding efficient and fair inter-piconet scheduling via simulation.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133353461","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}

Angle resolution at array endfires is improved which is often encountered in direction of arrival (DOA) finding problems. The algorithm extracts the azimuth and elevation angles directly from the estimated time delays between the array elements using the crosscorrelation. This algorithm offers several advantages. First, it is more efficient in terms of computational load. Secondly, the azimuth estimator does not require the a-priory knowledge of the wave propagation velocity. Thirdly, this algorithm is suitable for applications where the arrival time is the only measured input. Results are asymptotically unbiased having zero variance, meaning to statistical consistency.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131541519","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}

Design of such system revolves around the selection of proper function. An ideal hash function is the one that will never cause a collision. Although separate chaining and other techniques can be successfully applied for collision resolution, it is still a challenging job to find a suitable hash function. In this paper, we propose a simple technique that is based on a matrix of hash functions. A hash function is selected from the matrix based on message contents. With different hash functions used in single communication scenario, it is possible to strengthen the overall security of the system. Even if one of the hash functions is compromised, it is not possible to predict the next hash function associated with the message to calculate the message hash.","PeriodicalId":346773,"journal":{"name":"2007 International Conference on Emerging Technologies","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123679846","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}
