Modeling sage-grouse habitat using a state-and-transition model

Creator:: Evers, Louisa
Abstract:: Habitat for wildlife species that depend on sagebrush ecosystems is of great management concern. Evaluating how management activities and climate change may affect the abundance of moderate and high-quality habitat necessitates the development of models that examine vegetation dynamics, but modeling tools for rangeland systems are limited. I developed state-and-transition...

Improved design techniques for low-voltage low-power switched-capacitor delta-sigma modulators

Creator:: Grilo, Jorge
Abstract:: This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of improving the performance and optimizing for low power dissipation. This is accomplished by identifying critical elements whose performance can lead to increased power dissipation,...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:: Vargas, Oscar L.
Abstract:: Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

Identifying Quantitative Trait Loci for Resistance Against Stripe Rust and Septoria tritici blotch in Soft White Winter Wheat

Creator:: Cobertera, David
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) and Septoria tritici blotch (Zymoseptoria tritici) are a constant and significant threat to wheat production, significantly reducing wheat quality and yield. Wheat is responsible for 20% of the world’s human calorie intake, and wheat production must increase to supply the demand of the...

The effect of 2,4-D on the respiration rate and ethylene production of Bartlett pears and Red Delicious apples

Creator:: Fechtig, Allen David
Abstract:: After nearly 20 years of commercial use in orchards without apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy) acetic acid] was reported in 1970 to cause injury to apple and pear trees in Washington. In the early 1970's, there was widespread concern among growers, researchers, and processors in the...

Continuous time input pipeline ADCs

Creator:: Gubbins, David Patrick
Abstract:: Analog-to-digital converters (ADCs) convert analog continuous time signals into discrete time, digital format. One precondition that must be met for conventional nyquist rate ADCs is that the input signal must be suitably band-limited to an input bandwidth less than the nyquist frequency. This mandates expensive anti-alias filters which contribute to...

Abstract:: Nowadays, wireless communication systems use high-order quadrature amplitude modulation (QAM) together with orthogonal frequency-division multiplexing (OFDM) to increase the link capacity and robustness. These signals always have large peak-to-average power ratio (PAPR) and require power amplifiers (PAs) achieve both high efficiency and linearity simultaneously. For the efficiency, the complementary metal...
