Galvanic Vestibular Stimulation Applied To Flight Training, Joel D. Hanson
Galvanic Vestibular Stimulation Applied To Flight Training, Joel D. Hanson
Master's Theses
Between 1994 and 2003 spatial disorientation resulted in at least 202 aircraft
accidents, 184 of them resulting in fatalities. Galvanic Vestibular Stimulation (GVS)
provides a cost effective and safe way to simulate spatial disorientation and
potentially test pilot’s vestibular system prior to aircraft operation. This experiment
investigates the use of GVS as an indicator of motion sensitivity and explores the
effects of GVS on flight simulation performance. Bilateral bipolar rectangular pulse
electrical stimulations were given to subjects via skin-mounted electrodes placed over
each mastoid process to stimulate the vestibular system with roll and yaw sensations.
Two studies were conducted in …
Time-Frequency Analysis Of Intracardiac Electrogram, Erik Brockman
Time-Frequency Analysis Of Intracardiac Electrogram, Erik Brockman
Master's Theses
The Cardiac Rhythm Management Division of St. Jude Medical specializes in the development of implantable cardioverter defibrillators that improve the quality of life for patients diagnosed with a variety of cardiac arrhythmias, especially for patients prone to sudden cardiac death. With the goal to improve detection of cardiac arrhythmias, this study explored the value in time-frequency analysis of intracardiac electrogram in four steps. The first two steps characterized, in the frequency domain, the waveforms that construct the cardiac cycle. The third step developed a new algorithm that putatively provides the least computationally expensive way to identifying cardiac waveforms in the …
