Evaluating preconditioning options for the Jacobian-Free Newton Krylov Method applied to radiative transfer with matter coupling

Creator:: Myers, Nicholas T.
Abstract:: The objective of this thesis was to investigate the use of the Jacobian Free Newton Krylov Method (JFNK) with physics based preconditioning for solving coupled radiative transport and material energy balance. Modeling of these physics is important in inertial confinement fusion and other high energy density systems. In this thesis,...

Fourier-Transform Infrared Absorption Spectroscopy in Binary Hydrocarbon-Alcohol Single Droplet Evaporation

Creator:: Daly, Shane R., Olson, Nicholas, and Hagen, Christopher L.
Abstract:: Broadband absorption spectroscopy, by way of FTIR, was used to investigate the vapor cloud of a single millimeter sized liquid droplet suspended by a syringe as it evaporates at standard conditions. Single beam data were collected every 8 seconds resulting in a time-resolved record. Species concentrations were tracked using their...

Summer Low Flow Response to Timber Harvest and Riparian Treatments in Forested Headwater Streams of Coastal Northern California

Creator:: Nicholas, Jonah
Abstract:: Headwater streams represent the majority of the drainage area of a river network and provide many critical functions supporting aquatic and terrestrial ecosystem health. The riparian zones that surround these streams are transitional areas between terrestrial and stream ecosystems, which provide key habitat for aquatic and terrestrial organisms, especially during...

Automation and Evaluation of Graduated Dot Maps

Creator:: Arnold, Nicholas D.
Abstract:: Dot mapping is a traditional method for visualizing quantitative data, but current automateddot mapping techniques are limited. The most common automated method places dotspseudo-randomly within enumeration areas, which can result in overlapping dots and verydense dot clusters for areas with large values. These issues affect users’ ability to estimatevalues. Graduated...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Robotic Actuation and Control with Programmable, Field-Activated Material Systems

Creator:: Bira, Nicholas P.
Abstract:: This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...

Displacement-based fluorescent microRNA biosensors : design principles and analytical metrics

Creator:: Larkey, Nicholas E.
Abstract:: One post-transcriptional mechanism that regulates the progression of cancer and other diseases involves small 22-23 nucleotide sequences called microRNA (miR). Early detection of small changes in concentration of these biomarkers holds potential to diagnose diseases at their earliest stages. Use of current nucleic-acid based biosensors, like molecular beacons, for in...

Counterfactual thinking applied to multiagent systems

Creator:: Zerbel, Nicholas
Abstract:: Multiagent approaches are well suited to designing autonomous solutions for systems that feature complex interactions between many individuals such as in autonomous traffic systems and multi-robot exploration systems. However, creating autonomous agents that function effectively in these systems is a challenging task. In these complex environments, agents need informative reward...

Decentering the Human in 12th Century Histories and Chronicles: Divine Nonhumans at the Center of the Itinerarium Cambriae and the Historia Anglorum

Creator:: Phelps, Nathan J.
Abstract:: This thesis primarily investigates nonhumans in the writings of 12th century historians. Where these writings may typically be seen as having little room for nonhuman agency, this thesis investigates how divinity, as an important part of medieval life, creates a space for nonhuman agency that is otherwise overlooked. In chapter...

Urban ethnography : an exploration and interpretation of the post-camp period of Laotian refugees settling in Eugene-Springfield, Oregon

Creator:: Proudfoot, Robert Charles
Abstract:: This study employed ethnographic methodology to investigate and record the post-camp, pre-assimilation period of Laotian refugees.The primary goal was to document the special problems and experiences of the Laotian population as they attempted to adjust to new roles and expectations within mainstream North American society.Oral histories and biographical statements focused...
