Applications Of Quantifier Elimination Theory To Control Theory, C.T. Abdallah, P. Dorato, R. Liska, S. Steinberg, W. Yang
Applications Of Quantifier Elimination Theory To Control Theory, C.T. Abdallah, P. Dorato, R. Liska, S. Steinberg, W. Yang
Electrical & Computer Engineering Technical Reports
In this paper we show how a number of interesting linear control system analysis and design problems can be reduced to Quantifier Elimination (QE) problems. We assume a fixed structure for the compensator, with design parameters qi. The problems considered are problems that currently have no general solution, e.g. the output stabilization problem, the simultaneous stabilization problem, the robust multiobjective problem, etc. However, the problems must be of modest complexity if existing QE software packages are to produce answers. The software package QEPCAD is used to solve some numerical design examples.
The Role Of The Unconscious In The Perception Of Risks, Andrew F. Fritzsche
The Role Of The Unconscious In The Perception Of Risks, Andrew F. Fritzsche
RISK: Health, Safety & Environment (1990-2002)
Dr. Fritzsche argues that our world is too "rational" and that the psychology of the unconscious, as developed by Jung, can be key to understanding responses to hazards and to resolving conflicts that arise in the political management of risks.
The Influence Of Emotion On Temporal Perspectives, Skye Mims Ochsner
The Influence Of Emotion On Temporal Perspectives, Skye Mims Ochsner
Master's Theses
Recent research suggests that our understanding of the abstract domain of time is dependent on the more concrete domain of space. At once time is measurable and abstract, thus we often think of it both temporally as well as spatially. Boroditsky and Ramscar (2002) find that the spatial domain influences whether people see themselves as moving through time (ego-moving perspective) or as time moving towards them (timemoving perspective). Might there be other factors at work influencing these perspectives other than just representations of spatial experience? The current studies investigate the role that emotion plays in construal of time. Specifically, do …
Lack Of Racial Differences In Behavior: A Quantitative Replication Of Rushton's (1988) Review And An Independent Meta-Analysis, Kevin M. Gorey, Arthur G. Cryns
Lack Of Racial Differences In Behavior: A Quantitative Replication Of Rushton's (1988) Review And An Independent Meta-Analysis, Kevin M. Gorey, Arthur G. Cryns
Social Work Publications
Rushton (Personality and Individual Differences, 9, 1009–1024, 1988) hypothesized that racial group differences exist across a range of behaviors from intelligence to social organization. Such differences were then discussed within the context of an evolutionary continuum (Negroid < Caucasoid < Mongoloid). For example, his observations that blacks compared to whites are less intelligent, physically mature more rapidly, and are more aggressive and impulsive (less law abiding) were said to support the evolutionary hypothesis. Quantitative replication of the 100 studies included in Rushton's original ‘review and evolutionary analysis’ and a meta-analysis of 100 randomly selected studies infer that any behavioral differences which do exist between blacks, whites and Asian Americans for example, can be explained in toto by environmental differences which exist between them.
Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel
Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel
Theses : Honours
This thesis examines the effect of time delay and intervening items on masked repetition studies with word stem completion tasks. In the first experiment a masked priming effect was obtained. The effect was strongest 500ms after the presentation of the prime, and decreasing in a linear trend seven seconds after the presentation of the prime. The second experiment found that interpolating a naming task between the masked prime and the stem completion task eliminated the effects of the repeated masked prime. This result is a failure to replicate previous research which found a masked repetition effect over a short delay …
