How grouping improves the categorisation of frequency in song birds and humans and why song birds do it better
Njegovan, M.; Dept. of Psychol., Queen's Univ., Kingston, Ont., Canada - Weisman, R.; Dept. of Psychol., Queen's Univ., Kingston, Ont., Canada - Ito, S.; Dept. of Psychol., Queen's Univ., Kingston, Ont., Canada - Mewhort, D.; Dept. of Psychol., Queen's Univ., Kingston, Ont., Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	There is evidence that song bird species produce, recognize, and discriminate song notes on the basis of frequency within a range. How song birds do this is unknown. One hypothesis is that song birds represent individual frequencies separately, somehow knowing…

A PC based measurement system for obtaining spatial information and objective room-acoustic indicators
Abdou, A.; Centre for Building Studies, Concordia Univ., Montreal, Que., Canada - Guy, R.W.; Centre for Building Studies, Concordia Univ., Montreal, Que., Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	Over the last twenty years, many subjectively relevant objective room-acoustics quantities or indicators for evaluating the acoustical quality of an enclosure have been introduced. Whilst indicators give new insight into the acoustical goodness of a receiver position, there is still…

From microstructure to acoustic behaviour of porous materials
Perrot, C.; GAUS, Mechanical Engineering Department, Université de Sherbrooke, Sherbrooke, Que. J1K 2R1, Canada - Panneton, R.; GAUS, Mechanical Engineering Department, Université de Sherbrooke, Sherbrooke, Que. J1K 2R1, Canada - Olny, X.; LASH, DGCB URA CNRS 1652, Ecl. Natl. Travaux Pub. de l'Etal, 69518 Cedex, France

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	A method to determine the macroscopic parameters of absorbent materials from the knowledge of their cellular microstructure, either identified by computer microtomography or scaled by macro-micro geometrical model is discussed. All the relevant quantities have been computed on cellular systems.…

Hearing protectors - Calculations of the noise level at the protected ear
Behar, Alberto; IBBME, University of Toronto, Roseburgh Building, Toronto, Ont. M5S 3G9, Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	The risk of noise induced hearing loss, when wearing a hearing protector, can only be calculated with the knowledge of the noise level at the protected ear. Several methods are available for calculating this level, from the hearing protectors' attenuation…

Parallel recognizer algorithm for automatic speech recognition
Agbago, Akakpo; Institute for Information Technology, National Research Council of Canada, Pavillon Lucien Brault, 101 rue St-Jean-Bosco, Gatineau, Que. J8Y 3G4, Canada - Barrière, Caroline; Institute for Information Technology, National Research Council of Canada, Pavillon Lucien Brault, 101 rue St-Jean-Bosco, Gatineau, Que. J8Y 3G4, Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	A parallel recognizer algorithm for automatic speech recognition (ASR) was presented. This algorithm uses the principle of best-fit in an open competition for all phonemes in the Knowledge Base of Reference Phonemes (KBRP). The phonemes were concurrently matched in KBRP…

Detection and classification of North Atlantic right whales in the bay of fundy using independent component analysis
La Cour, Brian R.; Applied Research Laboratories, University of Texas at Austin, P.O. Box 8029, Austin, TX 78713 - Linford, Michael A.; Applied Research Laboratories, University of Texas at Austin, P.O. Box 8029, Austin, TX 78713

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	A novel method of detection and classification for marine mammals is presented which uses techniques from independent component analysis to solve the blind source separation problem for North Atlantic right whales (Eubalaena glacialis). Using the fundamentally non-Gaussian nature of marine…
