The presented research describes a sequence of methods to synthesize the sensor measurements\u0026nbsp;and estimate the model parameters; implementation considerations and potential problems are also presented.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"System Configuration for Proportional Control of an Assistive Technology for Patients with Cervical Spinal Cord Injuries "}],"uid":"28475","created_gmt":"2018-10-24 18:14:56","changed_gmt":"2018-10-24 18:14:56","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-11-05T10:00:00-05:00","event_time_end":"2018-11-05T12:00:00-05:00","event_time_end_last":"2018-11-05T12:00:00-05:00","gmt_time_start":"2018-11-05 15:00:00","gmt_time_end":"2018-11-05 17:00:00","gmt_time_end_last":"2018-11-05 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"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":""}}}
