Bird voices were recorded in a highly noised municipal environment. High 96 kHz sampling frequency has been used in order to record birds' voices. As a feature set standard mel-frequency cepstral coefficients (MFCC) and recently proposed human-factor cepstral coefficients (HFCC) parameters were selected. Superior performance of the HFCC features over MFCC ones has been observed. Proper limiting of the maximal frequency during HFCC feature extraction results in increasing accuracy of birds' species recognition. Good initial results are very promising for practical application of the methods described in the paper in monitoring of protected birds' area.","PeriodicalId":274617,"journal":{"name":"Signal Processing Algorithms, Architectures, Arrangements, and Applications SPA 2007","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121638547","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}

It is supposed that a priori information concerning the signal duration and time delay is unknown. In this case the WVD of the signal can be splitted and performance characteristics degrade. The computer simulations are carried out for different values of the moving window width, search velocity and signal-to-noise ratio (SNR).","PeriodicalId":274617,"journal":{"name":"Signal Processing Algorithms, Architectures, Arrangements, and Applications SPA 2007","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125626890","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 key idea is to employ the redundancy of operators in the data path of a VLIW processor. I.e., every operation is executed twice by two different operators during normal program execution. Only in case a mismatch between both computed results occurs, the operation is executed by a third operator. Therefore, during most of the execution time, the third operator can be used for executing regular operations of the program. We propose modifications of the VLIW architecture in order to detect a mismatch in computed results. Necessary program transformations are introduced, in order to obtain an internal representation for fault tolerant programs that can be scheduled to the proposed VLIW architecture. Furthermore, we propose the program execution model that is used in case a permanent fault in the data path has been detected and give some preliminary results.","PeriodicalId":274617,"journal":{"name":"Signal Processing Algorithms, Architectures, Arrangements, and Applications SPA 2007","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127424677","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}
