Enhanced-accuracy oversampled data converters

Creator:: Ceballos, Jose Luis
Abstract:: Digital-to-analog converters (DACs) suffer from static and dynamic nonlinearity problems, which degrade their accuracy and performance. Mismatch errors in the analog components restrict the maximum achievable linearity. This thesis presents various techniques for correcting these errors. It describes a correction process for the nonlinear behavior of DACs, on three different...

Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

An on-line advanced plant simulator (OLAPS)

Creator:: Samuels, Jeffery W.
Abstract:: A PC based on-line advanced plant simulator (OLAPS) for high quality simulations of Portland General Electric's Trojan Nuclear Facility is presented. OLAPS is designed to simulate the thermal-hydraulics of the primary system including core, steam generators, pumps, piping and pressurizer. The simulations are based on a five equation model that...

The role of sulfur in the preservation of isoprenoid hydrocarbons in sedimentary materials of the Washington continental margin

Creator:: Pinto Alvarez, Luis A.
Abstract:: A systematic study of highly branched isoprenoids (HBI) was carried out in suspended particulate material (SPM) and Washington coastal sediments to determine their origin and fate. SPM collected at 10 m depth was filtered through Nitex membranes. C₂₅ HBI were found only in the 1.2-40 μm range over the shelf....

The fishery biology of the weathervane scallop [Pecten (Patinopecten) caurinus Gould, 1850] in Oregon coastal waters

Creator:: Nunez, Jose D.
Abstract:: Samples of weathervane scallops taken on Oregon Department of Fish and Wildlife cruises off Oregon waters during 1981-1982 were analyzed for a comparative growth study. No evidence of internal growth marks were found in the shell structure when analyzed by the acetate peel technique. Internal growth lines formed in the...

Carbene rearrangements : intramolecular interaction of a triple bond with a carbene center

Creator:: Dan̄ino, José C.
Abstract:: The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2- heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2- one were synthesized and decomposed under a variety of reaction conditions: dry lithium and sodium salt pyrolyses, sodium methoxide thermolyses in diglyme and photolyses of the lithium salt in tetrahydrofuran. The saturated analogues 2-heptanone tosylhydrazone and its 4,4-dimethyl isomer afforded the...

Impacts of instream flows on the Colorado River Delta, Mexico : spatial vegetation change analysis and opportunities for restoration

Creator:: Zamora-Arroyo, Jose Francisco
Abstract:: Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...
