Topologically-Guided Robotic Information Gathering

Creator:: McCammon, Seth
Abstract:: Information gathering tasks, such as terrestrial search and rescue, aerial inspection, and marine monitoring, require robotic unmanned systems to make decisions on how to travel within an environment to maximize or minimize a path-dependent information objective function. The distribution of information throughout the environment is the result of various processes,...

Kinematics and Dynamics of a Model Eastern-boundary Poleward Undercurrent

Creator:: Duran, Rodrigo
Abstract:: A carefully calibrated primitive-equation model from 41°N to 48°N is used to study the poleward undercurrent off the US west coast. Chapter 2 describes poleward flow over the slope from Eulerian and Lagrangian perspectives. The model is robust, in the sense of several characteristics being qualitatively consistent with observational and...

Sea surface height and geostrophic velocity variability in the California current system as observed from the TOPEX altimeter

Creator:: Righi, Dylan D.
Abstract:: Eight years (1994-2000) of data from the TOPEX/Poseidon satellite altimeter are used to investigate the variability of the sea surface height and geostrophic velocity of the California Current system. The TOPEX/Posiedon satellite measures SSH along an exact-repeat set of groundtracks with a 10-day repeat cycle. In the domain studied here...

Database development and application to characterize juvenile Douglas-fir (Pseudotsuga menziesii [Mirb] and understory vegetation in the Oregon and Washington Coast Range Mountains

Creator:: Shula, Robert G.
Abstract:: The Regional Vegetation Management Model (RVMM) predicts the effects of associated vegetation on the growth and yield of young Douglas-fir (age [less than or equal to] 20 years) in the Pacific Northwest, and is a 'front-end' growth model for existing rotation-age growth models. Objectives of this thesis are to: (a)...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

Creator:: Gervais, Jennifer A.
Abstract:: Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...

Light-matter interactions : from the photophysics of organic semiconductors to high spatial resolution optical tweezer-controlled nanoprobes

Creator:: Kendrick, Mark J.
Abstract:: Studies of light-matter interactions in organic semiconductors and in optical tweezer trapping of nanoparticles are presented. In the research related to organic semiconductor materials, a variety of novel materials and their composites have been characterized, and physical mechanisms behind their optoelectronic properties have been established. Three novel functionalized hexacene derivatives...

The inherent optical properties of the oceans: from closure to prediction

Creator:: Barnard, Andrew Heath
Abstract:: Precise in situ measurement of the spectral absorption and scattering coefficients in several regions has revealed patterns in the distribution of the inherent optical properties on spatial scales that were previously unobtainable. The precision of the measurements was found to be consistent and unbiased across a variety of oceanic regimes...

Scratch Explorer : a tool for assisting end-user program comprehension of animation scripts

Creator:: Zhang, Yan
Abstract:: Visual programming languages (VPLs) have been widely used to support end-user programming. However, end users are still not able to reuse code as actively as professional programmers, even when given abundant resources such as a large VPL program repository. One reason may be that current VPL development environments lack features...

The South Atlantic Ocean response to local and remote forcings

Creator:: Fetter Filho, Antonio F. H.
Abstract:: The local and remote sources of variability of the South Atlantic Ocean are investigated using a set of numerical experiments and satellite data. A global, eddy-permitting, numerical simulation is analyzed to investigate the dynamical links between the Antarctic Circumpolar Current (ACC) and the Malvinas Current (MC). The model results indicate...
