A quadratic programming algorithm for deriving efficient farm plans in a risk setting

Creator:: Bauer, Leonard
Abstract:: The main focus was on developing an algorithm and supporting computer programs for use by extension personel to counsel farm managers on problems of enterprise choice. Investigation was initiated from the complete certainty viewpoint of linear programming. Upon introducing uncertainty, ramifications of changing expected income, variance and the correlation coefficient...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Survival and growth patterns of white spruce (Picea glauca [Moench] Voss) rangewide provenances and their implications for climate change adaptation

Creator:: Lu, Pengxin, Parker, William H., Cherry, Marilyn, Colombo, Steve, Parker, William C., Man, Rongzhou, and Roubal, Ngaire
Abstract:: Intraspecific assisted migration (ISAM) through seed transfer during artificial forest regeneration has been suggested as an adaptation strategy to enhance forest resilience and productivity under future climate. In this study, we assessed the risks and benefits of ISAM in white spruce based on long-term and multilocation, rangewide provenance test data....

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Psychological and Linguistic Processes in Treatment Related Text Messages

Creator:: Partch, Megan A.
Abstract:: Treatment providers seek low-cost, high-impact means of engaging clients in care with the aim to enhance treatment delivery and outcomes. With improvements to mobile technology making cell phone accessibility and usage rates high across all socio-economic levels, text messaging is becoming more frequently utilized as a means of promoting provider-client...

Risk-based design for multidisciplinary complex systems

Creator:: Farhangmehr, Farzaneh
Abstract:: The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

Technical change and pollution abatement costs

Creator:: Färe, Rolf, Grosskopf, Shawna, and Pasurka, Carl
Abstract:: There is continuing interest in the trend of costs associated with pollution abatement activities. We specify an environmental production technology to model the joint production of good and bad outputs. The joint production model calculates pollution abatement costs and identifies changes in these costs associated with: (1) technical change, (2)...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...

Intensity oscillations in the carbon 1s ionization cross sections of 2-butyne

Creator:: Carroll, Thomas X., Zahl, Maria G., Børve, Knut J., Sæthre, Leif J., Decleva, Piero, Ponzi, Aurora, Kas, Joshua J., Vila, Fernando D., Rehr, John J., and Thomas, T. Darrah
Abstract:: Carbon 1s photoelectron spectra for 2-butyne (CH3C CCH3) measured in the photon energy range from threshold to 150 eV above threshold show oscillations in the intensity ratio C2,3/C1,4. Similar oscillations have been seen in chloroethanes, where the effect has been attributed to EXAFS-type scattering from the substituent chlorine atoms. In...

Abstract:: The Lena River in central Siberia is one of the major pathways translocating terrestrial organic matter (OM) from its vast catchment area to the coastal zone of the Laptev Sea and the Arctic Ocean. The permafrost soils of its far south-stretching catchment, which store huge amounts of OM, will most...
