Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...
The growth of YMn₀.₃₅In₀.₆₅O₃ thin films and their optical and magnetic behavior are reported. The YMn₀.₃₅In₀.₆₅O₃ thin film grows along the (0001) orientation with hexagonal structure similar to YMnO₃ on c-plane sapphire. The film shows paramagnetic behavior in the temperature range measured. The film exhibits a blue color due to...
As robotic systems become increasingly prevalent in our lives (e.g., by harvesting food, assisting with disaster response and defense, and transporting persons and our goods around the world) there is a growing need to ensure that they can cooperate to achieve their intended goals. Robotic cooperation in the real-world is...
This work proposes a technique for distributed multi-robot exploration that leverages novel methods of map inference. The inference technique uses observed map structure to infer unobserved map features. The team then coordinates to explore both the inferred and observed portions of the map. Individual robots select exploration poses by accounting...
Crystallizing a virus can be difficult and not always successful. Forty-eight salts, buffers, and precipitating agents were used in the hanging drop preparations in attempts to crystallize the San Miguel sea lion virus type 5 (SMSV-5). The first attempt resulted in 22 of the 48 solutions forming a precipitate. The...
The objectives of this study were:
1. To identify factors which contribute to the success of a
fiber artist in Oregon, including skills or knowledge gained from
training or experience.
2. To draw up recommendations for use by colleges and universities
to facilitate the evaluation of programs designed to train...
There is a shortage of qualified community college technical instructors in new and emerging technologies. The purpose of this study was to investigate the barriers that may affect the decision of semiconductor specialists to teach part-time at community colleges. The desired outcome is to enable community colleges to increase the...
The study extends from the mouth of the Columbia River to River Mile 46. It has four elements: an overview of transportation infrastructure, dredging requirements and other constraints and opportunities; identification of potential development sites; description of estuarine impacts; and a review of policy and mitigation strategies. The study in...
The status of vitamin B-6 (B6) nutriture of nine
persons (4F;5M) with insulin dependent diabetes mellitus
(IDDM), nine persons (5F;4M) with non-insulin dependent
diabetes mellitus (NIDDM), and 18 control individuals
(9F;9M) was evaluated, using biochemical and dietary
indicators of B6 status. The biochemical indices employed
were plasma concentration of pyridoxal...
