1	Practice effects, emotion, and mechanisms of dual-task interference in driving and cell phone research Lightman, Erin 18 May 2010 (has links) Decades of research suggest that talking on a cell phone interferes with driving performance, but the underlying mechanisms of this interference remain poorly understood. Driving and cell phone research often generalizes easy, novice laboratory tasks to the well practiced task of driving, and it frequently ignores important factors like emotion in tasks used to represent cell phone conversation. This experiment sought to address these issues. Participants performed a tracking task and two verbal tasks over 7 one-hour sessions. At some times the tasks were performed individually, and at others the tracking task was performed concurrently with one of the verbal tasks. Participants watched an anger-inducing film clip at the beginning of the 7th session and were instructed to either down-regulate or maintain that anger. Results challenged the validity of generalizing easy novice task performance to driving performance.

2	A non-conventional multilevel flying-capacitor converter topology Gulpinar, Feyzullah January 2014 (has links) Indiana University-Purdue University Indianapolis (IUPUI) / This research proposes state-of-the-art multilevel converter topologies and their modulation strategies, the implementation of a conventional flying-capacitor converter topology up to four-level, and a new four-level flying-capacitor H-Bridge converter confi guration. The three phase version of this proposed four-level flying-capacitor H-Bridge converter is given as well in this study. The highlighted advantages of the proposed converter are as following: (1) the same blocking voltage for all switches employed in the con figuration, (2) no capacitor midpoint connection is needed, (3) reduced number of passive elements as compared to the conventional solution, (4) reduced total dc source value by comparison with the conventional topology. The proposed four-level capacitor-clamped H-Bridge converter can be utilized as a multilevel inverter application in an electri fied railway system, or in hybrid electric vehicles. In addition to the implementation of the proposed topology in this research, its experimental setup has been designed to validate the simulation results of the given converter topologies.
