The Mars Science Laboratory mission aims to land a car-sized rover on Mars’ surface and operate it for at least one Mars year in order to assess whether its field area was ever capable of supporting microbial life. Here we describe the approach used to identify, characterize, and assess environmental...
The Phoenix mission, launched on 4 August 2007, landed in the far northern
plains of Mars on 25 May 2008. In order to prepare for the landing events and the
90-sol mission, a significant amount of work has gone into characterizing the atmospheric
environment at this location on Mars for...
Statistical modeling has evolved around building increasingly more complex models, even though it is common knowledge among statisticians that an optimal model size usually exists for any given data set. Having overly complex models leads to imprecise parameter estimates and tends to increase the subjective role of the modeler, which...
A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...
Kanter (1977) conceptualized five dimensions of the
interdependence between work and family: occupational
subculture, job absorption, time and timing, rewards and
resources, and the emotional climate of work. Each of
these dimensions affects the functioning and satisfaction
of families and marriages. This research examined how
four of these dimensions (occupational...
Much of our knowledge about transgender (folks who identify as not cisgender) lives in universities centers around barriers experienced, feelings of exclusion, and being victims of harassment and violence. This thesis describes conversations regarding captured gender euphoric moments from five students at a large university. They came together through a...
Image segmentation continues to be a fundamental problem in computer vision and image understanding. In this thesis, we present a Bayesian network that we use for object boundary detection in which the MPE (most probable explanation) before any evidence can produce multiple non-overlapping, non-self-intersecting closed contours and the MPE with...
Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some...
