Assembly time estimation is a key factor in evaluating the performance of the assembly process in an automated assembly process. The overall goal of this study is to develop an efficient assembly time estimation method by generating the prediction model from an experimental design. In order to estimate these times,...
Bone strength and fracture resistivity are related to a variety of factors encompassed in what is referred to as bone quality. However, bone quality is not a well-defined concept; therefore individual fracture risk cannot be predicted accurately, and osteoporosis treatment monitoring remains di cult. Clinically available imaging modalities use bone...
This study uses an existing database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation are used to develop an effective stress-based...
The ternary system (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-Bi(Mg₀.₅Ti₀.₅)O₃ (BNT-BKT-BMgT) was explored along the [75-(x 2) ]Bi₀.₅Na₀.₅TiO₃ - [25-(x 2)]Bi₀.₅K₀.₅TiO₃ - [x]Bi(Mg₀.₅Ti₀.₅)O₃ composition line. Thin films were fabricated using chelated mixing route solutions spin cast onto platinized silicon substrates. Processing parameters such as: excess cation molar%, solution molality, and crystallization temperatures, for composition where x=0,...
Soft robots are designed to utilize their compliance and contortionistic abilities to both interact safely with their environment and move through it in ways a rigid robot cannot. To more completely achieve this, the robot should be made of as many soft components as possible. Here we present a completely...
The effects of alfaxalone (A-HPCD), propofol (P), ketamine-diazepam (KD) and tiletamine-zolazepam (TZ) administered IV in dogs on cardiovascular and respiratory systems, acid-base balance and electrolytes have been reported in the literature, but a study that compares IV TZ to the other induction protocols (IP) is needed. Six dogs enrolled in...
This thesis provides a comparison of advanced econometric frameworks to account for unobserved factors in crash reported data (also referred to as unobserved heterogeneity) while identifying contributing factors by roadway classification for heavy vehicle injury severity and crash rates. The presented thesis provides two manuscripts that expand the literature regarding...
Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....
This project determines the short term and long term effective stiffness values for Cross Laminated Timber (CLT) with a reinforced concrete topping. The reinforced concrete was attached to the CLT panels with interface connections, and different types of interface connections were tested. Throughout this project, there are 31 tests with...
Forest soils and topography have long been known to influence forest productivity in complex terrain such as Oregon’s Coast Ranges. Incorporating physical site characteristics into predictions of forest growth and yield, however, has been problematic because of the high spatial variability of soil properties and the challenges associated with representing...
