While working and subsequent rest operator passes through the phases of mobilization, stabilization, work, recovery and the rest. The amplitude and frequency of non-stationary periods of cardiac rhythm indicates the human resistance to stressful conditions. We introduce and analyze a number of algorithms for non-stationary phase extraction: the different approaches to phase preliminary detection, thresholds extraction and final phases extraction are studied experimentally.<\/jats:p>","DOI":"10.3233\/978-1-61499-714-6-197","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:21:00Z","timestamp":1740133260000},"source":"Crossref","is-referenced-by-count":0,"title":["Adaptive Techniques for Extracting Mental Activity Phases from Heart Beat Rate Streams"],"prefix":"10.3233","author":[{"family":"Dubatovka Alina","sequence":"additional","affiliation":[]},{"family":"Mikhailova Elena","sequence":"additional","affiliation":[]},{"family":"Zotov Mikhail","sequence":"additional","affiliation":[]},{"family":"Novikov Boris","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Databases and Information Systems IX"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:21:52Z","timestamp":1740133312000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-713-9&spage=197&doi=10.3233\/978-1-61499-714-6-197"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-714-6-197","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2016]]}}}
