Recent advancements in unmanned aerial vehicle (drone*) technology, sensors, and software applications have increased efficiency in data collection, reduced human error, and increased safety while managing a wide range of projects. No longer relegated solely to military use, drones have become synonymous with picturesque views of natural wonders and resources...
Successful pruning relies on accurately identifying the 3D structure of tree branches and leaders. However, this task is arduous in an agricultural setting due to the complexity of scenes, the presence of clutter, and variable weather conditions. This project addresses these challenges by leveraging advancements in 2D image segmentation and...
Reinforcement learning has made impressive strides in solving problems in challenging domains, but problems are increasingly being described with sparse rewards. Sparse rewards directly reduce the rate at which useful feedback is provided to the learner and make it difficult to distinguish between what specific actions led to the reception...
This paper explores predictors of support for land-use ballot initiatives in Oregon. Possible predictors include a variety of socioeconomic, spatial, and political variables.

In the context of expanding global food trade in which we import and consume a variety of foods from across the world, insuring food safety, an essential public health issue, has become a major concern in our food supply system. Over the past several years, food related scandals of Chinese...
Polyoxoniobates (PONbs) are attracting great attention in recent years due to its novelty as well as a variety of geometrical presentations in different pH conditions. In this paper we are reporting the reaction of tetramethyl-decaniobate ([(CH3)4N]6[Nb10O28]) with alkaline carbonates to observe the periodic trend of alkaline ions interacting with the...
As the threat of climate change becomes more imminent and the role of cities in climate adaptation becomes clearer, urban resilience, the ability of a city or urban system to withstand a wide array of shocks and stresses, has gained increasing attention in climate adaptation policy and planning. Critics of...
River ecosystems throughout the arid southwestern U.S. are imperiled. Water management infrastructure, climate change, unsustainable water use, and political conflict harm the region's aquatic and riparian ecosystems. This case study surveys one such desert river, an endemic fish species, and conservation efforts in southwestern Utah. The analysis focuses on the...
This essay provides an assessment of the human, social and financial resources that Oregon Latino immigrant-serving nonprofits have available to achieve their mission of promoting Latino immigrant integration and civic engagement practices. Under the framework of immigrant integration, this study examines the strategies Latino nonprofits rely upon to achieve their...
This capstone project is presented for the completion of Oregon State University’s (OSU) Master of Natural Resources Program. Water resource reliability in the Pacific Northwest is becoming less dependable, but population and municipal water demand is increasing. The Gales Creek Watershed and its tributary Clear Creek encompass 48,481 acres in...
