The contributions of this research can be divided into three main parts: 1) improving STIs estimation from BCG\u0026nbsp; using a high bandwidth force plate and leveraging the increase in accuracy to estimate per-subject stroke volume changes; 2) investigating the effect of different sensor placements on the accuracy of SCG-based PEP estimation, and devising a method to classify SCG sensor positioning in unsupervised settings to prevent misleading estimations; 3) Combining SCG signals from an array of multiple accelerometers to obtain a signal that is more representative of the response of the entire body from cardiac ejection, rather than of local chest vibrations.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Robust Estimation of Systolic Time Intervals using Ballistocardiogram and Seismocardiogram"}],"uid":"28475","created_gmt":"2016-11-09 21:49:10","changed_gmt":"2016-11-23 21:43:44","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-12-01T11:30:00-05:00","event_time_end":"2016-12-01T13:30:00-05:00","event_time_end_last":"2016-12-01T13:30:00-05:00","gmt_time_start":"2016-12-01 16:30:00","gmt_time_end":"2016-12-01 18:30:00","gmt_time_end_last":"2016-12-01 18:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
