First order prism slip in yttrium single crystals containing a total interstitial impurity content of about 200 wt ppm is almost entirely stage II deformation with a work hardening rate θ/μ of 2·10⁻ ³ . The athermal temperature is about 300°K. Below this temperature an interstitial mechanism is rate controlling...
Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...
Vegetable production with a living mulch may reduce soil erosion and compaction, increase organic matter levels, and decrease the requirement for chemical inputs. Competition between the vegetable and mulch, however, has limited the development of successful living mulch systems to realize these benefits. In a field study, interference between pak...
A mathematical model was developed to simulate alternative
selection and crossbreeding strategies for commercial beef production.
Biological and economic constraints were selected to represent
typical pasture production of calves in the Northwest. The
crossbreeding study evaluated the relative economic efficiency of
different 1) mating plans when sire breeds of several...
The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...
Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...
When treating highly infectious diseases, patient compliance with caregiver recommendations is crucial. Many patients who contract Ebola Virus Disease have symptoms including vomiting and severe diarrhea and die from the resulting dehydration if they do not drink enough fluids. Telepresence robots are useful in the context of Ebola treatment for...
Twenty-four years of records (1958-1981) from a commercial Angus ranch were utilized in a population analysis to characterize the herd as a biological unit. The herd averaged 632±129 cows and 123±6 replacement heifers with all replacement heifers and many bulls from within the herd. Life tables were calculated for seven...
This dissertation focuses on personal privacy in human-robot interaction, which we call "privacy-sensitive robotics." Our understanding of "privacy" is very broad, including not just information privacy but also physical, psychological, and social privacy. We begin by surveying the scholarly literature on privacy and talking about why it applies to interactions...
