Effect of using a wavelength shift keying (WSK) scheme is analyzed and compared to that of the conventional on off keying system (OOK) in respect of four wave mixing (FWM) cross talk. The performance results are evaluated at a bit rate of 10Gb/s taking into considerations the combined influence of photo detector shot noise, beat noise components arising out of the beating of the signal with accumulated amplifier's spontaneous emission (ASE) and cross talk introduced at each node due to four wave photon mixing. The computed results show that for 50 hops the bit error rate (BER) of the standard wavelength division multiplexing (WDM) system is higher than 10-12 while for the wavelength shift keying system, for the same received power the BER is lower than 10-16 for the hop length of 100 km. It is also shown that for a given BER, WSK-WDM technique provides higher values of both the maximum allowable number of hops and minimum required power.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114158940","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}

We use the HTK Toolkit in preprocessing acoustic signals including feature extraction from the Thai music collection. The training set consists of 250 songs -50 songs from each of the 5 genres. Training is divided into three phases using all or some of these songs. The test set consists of 10 songs selected from 5 genres which are not included in training. We trained and tested the music classifiers using both TreeQ and LVQ algorithms with varying parameters such as, Number of Codebook (NOC) and pruning thresholds to identify the effects of different parameters and features in the Thai music classification and retrieval. We observed that TreeQ-based experiments yield faster response-times than those of LVQ; and therefore, a TreeQ-based system maybe appropriate for online (real-time) music retrieval tasks. On the other hand, LVQ-based experiments consistently yield better accuracy than those of TreeQ; and therefore, a LVQ-based system may be appropriate in the music classification task since music classification can generally be performed off-line. We also outlined a Relevance Feedback based Music Retrieval System in this paper.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115852790","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}

Hence in this paper, we present a method of automatic detection and reduction of ECG artifact from EEG. ECG has its own spike like property and periodicity. Moreover, it also has lack of correlation with the EEG signal. We have utilized the aforementioned properties to detect ECG artifact in EEG and have employed a method to remove it automatically. In the first step of the algorithm, an energy function based method is used to emphasize the R-waves of contaminated ECG artifact and thereafter, an adaptive thresholding method along with clustering is used to detect contaminated candidate R-spikes of ECG artifact in EEG signal. After that utilizing periodic information of R-wave, a searching mechanism is employed as post processing to detect the R-peaks more accurately. Thereafter, noise model of ECG artifact contaminated with EEG is generated and finally it is subtracted from the EEG recordings to decontaminate it from the artifact. Before subtraction, a time varying alignment procedure is applied to increase the effectiveness of the artifact reduction method. Results obtained from our extensive experiments show that the proposed method is effective and encouraging in terms of automatic ECG artifact detection and reduction from EEG signal.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128495627","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}
