Himeradine A : synthetic efforts towards himeradine A and related natural products, a Michael reaction focused approach

Creator:: Collett, Nathan D.
Abstract:: Lycopodium alkaloids have generated enormous amounts of interest from the scientific community, both as synthetic targets and for their medicinal properties. Herein is described work towards a unifying approach to large segments of the Lycopodium family. An organocatalyzed intramolecular heteroatom Michael reaction method, for the construction of piperidine and piperizine...

Analysis and modeling of microstrip on-chip interconnects on silicon substrate

Creator:: Lan, Hai
Abstract:: The electrical performance of on-chip interconnects has become a limiting factor to the performance of modern integrated circuits including RFICs, mixed-signal circuits, as well as high-speed VLSI circuits due to increasing operating frequencies, chip areas, and integration densities. It is advantageous to have fast and accurate closed-form expressions for the...

Ductile fracture of metals under triaxial states of stress

Creator:: Schrems, Karol Krumrey
Abstract:: Silver interlayers between maraging steel base metal were examined to evaluate mechanisms leading to ductile failure in constrained thin metals. The constraint of the maraging steel base metal during uniaxial testing of constrained thin silver results in a large hydrostatic tension component, a small von Mises effective stress, and negligible...

Modeling and experimental validation of supercapacitors for use in an in-lab grid developed for wind integration applications

Creator:: Naswali, Eunice
Abstract:: The fast growth of wind energy utilization has necessitated research into wind energy integration. Due to the variable nature of wind and the forecasting challenges, it is desirable to utilize wind energy alongside energy storage sources for reliable wind energy integration. This work details the design of a 25 kW...

Atomic layer deposition of nanolaminate high-κ gate dielectrics for amorphous-oxide semiconductor thin film transistors

Creator:: Triska, Joshua B.
Abstract:: Nanolaminate dielectrics combine two or more insulating materials in a many-layered film. These structures can be made to significantly outperform films composed of a single one of their constituent materials by adjusting the composition ratio, arrangement, and size of the component layers. In this work, atomic layer deposition (ALD) is...

Development of a variable-speed, doubly-fed wind power generation system

Creator:: Brune, Christopher S.
Abstract:: Generation of electricity from the wind is becoming increasing popular as an environmentally responsible resource. Current methods for generating electricity from the wind involve the use of fixed-speed generators. However, the use of variable-speed generators increases the amount of energy that can be extracted from the wind. Most variable-speed technologies...

Investigating arc behavior in a DC vacuum arc remelting furnace using magnetic flux density measurements

Creator:: Woodside, Rigel
Abstract:: The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...

MCNP5 modeling of the Oregon State TRIGA Reactor for skyshine dose estimation after a loss of coolant accident

Creator:: Sarmast, Katharine Danielle
Abstract:: This thesis evaluates dose rates from the TRIGA® reactor by comparing ion chamber measured exposure rates to exposure rates calculated from MCNP5 model data. The first step evaluates the energy distribution required to match ion chamber exposure rates from measurements taken at 1 foot increments above the reactor core. Next,...

Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

Creator:: Beck, H. Greeley
Abstract:: Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...
