The present highway funding system, especially fuel taxes, may become less reliable revenue sources in the future, while the transportation public agencies do not have the sufficient financial resources needed to meet the increasing traffic demand. Regarding the socio-economic impact of road privatization, a wide range of approaches and models...
In this dissertation, I describe the experimental investigation of electron diffraction of neutral and ionic clusters doped into superfluid helium droplets. The project is aimed at contributing to the development of an overall approach called ‘serial single molecule electron diffraction imaging (ss-EDI), a potential approach to solve macromolecule structures bypassing...
In this work, a hybrid thermochemistry compressed air energy storage (CAES) system is investigated. Following a review on chemical reactions investigated for use in thermochemical energy storage (TCES) systems, from these chemistries, the conversion of magnesium carbonate, MgCO3, to magnesium oxide, MgO, and carbon dioxide, CO2, was further analyzed for...
Oregon’s gasoline tax no longer serves as an economically efficient revenue source due to increasing fuel efficiency and the emergence of alternative fuels. In response to this problem, the Oregon Department of Transportation is exploring alternatives to the gasoline tax. Among the most promising alternatives is a flat-rate vehicle mile...
Polyoxoniobates (PONbs) are attracting great attention in recent years due to its novelty as well as a variety of geometrical presentations in different pH conditions. In this paper we are reporting the reaction of tetramethyl-decaniobate ([(CH3)4N]6[Nb10O28]) with alkaline carbonates to observe the periodic trend of alkaline ions interacting with the...
Reliable controller designs have been developed in this thesis for a number of finite-horizon
and infinite-horizon problems with possibly non-zero initial conditions. These
reliable controllers assure that system stability and system performance will be
maintained despite certain system faults. The performance measure used in this thesis is
an "H[subscript ∞]-like...
The purpose of this thesis is to apply the Canonical Correlation
Analysis (CCA) which belongs to the parametric methods for power
spectral estimation in the environments of either white noise or
colored noise. It is shown that optimal state space variables
belong to the range space of the canonical vectors...
The response of lightweight equipment in structures supported on
resilient-friction-base isolators (R-FBI) subjected to harmonic ground motion and various
earthquake ground motions is examined. The equipment-structure base system is modeled
as a three degree-of-freedom discrete system (SDOF subsystems). An efficient
semi-analytical numerical solution procedure for the determination of equipment response...
This study was to investigate effects of growth rate
and cambial age on properties of wood from two increasingly
used hardwood species, red alder (Alnus rubra Bong.) and
Oregon white oak (Quercus garryana Dougl.), for better
understanding factors affecting wood quality in hardwoods.
Thirty 7-year-old trees grown at widely varying...
