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...
Latinos are the largest and most rapidly growing ethnic minority in the United States, and they have the highest dropout rates of any major ethnic group in the country (U.S. Department of Labor, 2003). Latinos' educational attainment is consistently lower than that of other students (Gandara, 2008). The majority of...
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...
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...
The purpose of this research project was to gain a deeper understanding of the
lived experience of faculty of color. More specifically, this project explores how
diversity-related workload expectations impact faculty of color who work in
predominantly white community colleges. Known by various descriptors, the term
used in this research...
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...
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...
The possible effect of oxidation [processing with or without sulfur dioxide
(±S0₂)] and of pre-ultrafiltration treatment of juices with enzymes and fining
agents on flux, and on juice color, composition and stability was investigated. White
Riesling juice was ultrafiltered with a Romicon system operated with a nominal
molecular weight cut-off...
Learning novel concepts from relational databases is an important problem with applications in several disciplines, such as data management, natural language processing, and bioinformatics. For a learning algorithm to be effective, the input data should be clean and in some desired representation. However, real-world data is usually heterogeneous – the...
The Department of Nuclear Engineering and Radiation Health Physics (NE/RHP) at Oregon State University (OSU) has been developing an innovative modular reactor plant concept since being initiated with a Department of Energy (DoE) grant in 1999.
This concept, the Multi-Application Small Light Water Reactor (MASLWR), is an integral pressurized water...
