This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...
Lab notebooks with lengths and weights of tested samples. Includes capture dates, depths and dates samples went into detector. Date of coverage: 11/28/91 to 11/12/65.
The purpose of this study was to evaluate the impact sediment has on the survival of
bacteria in a typical rangeland stream. This information is an important component in
determining a time integrated prediction of bacterial numbers in the stream sediment and
overlying water. Bacterial survival in stream is a...
The Oregon Foundation Seed & Plant Materials Project (FS&PMP) is charged with maintaining, increasing, and distributing early generation planting stock of grains, grasses, legumes, potatoes, grapes, and mint to Oregon growers. Early generation seed and plant materials are released to Foundation seed programs for the production of the Foundation class...
In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...
This biological assessment (BA) documents the potential effects of existing Forest Service (FS) Land and Resource Management Plans (LRMPs), or 'Forest Plans' and Bureau of Land Management (BLM) Land Use Plans (LUPs) on the Canada Lynx (Lynx canadensis), hereafter referred to as the lynx. LRMPs and LUPs are collectively referred...
Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...
In the past decades, femtosecond stimulated Raman spectroscopy (FSRS) has been gaining tremendous popularity in fundamental sciences stemming from chemistry to biology. It is capable of capturing both equilibrium and non-equilibrium structural information across a broad range of timescales with simultaneously high temporal and spectral resolutions. Femtosecond transient absorption spectroscopy...
Low-frequency vibrations are foundational for material properties including thermal conductivity and chemical reactivity. To resolve the intrinsic molecular conformational dynamics in condensed phase, we implement time-resolved third-harmonic generation (TRTHG) spectroscopy to unravel collective skeletal motions in calcite, water, and aqueous salt solution in situ. The lifetime of three Raman-active modes...
The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...
