Wave energy has a promising future, especially for the Pacific Northwest, and Oregon, pioneering the way to meet Oregon’s goal of 25% renewable energy by 2025. The project represents a significant ability to harness the untapped potential energy of ocean waves, and maintains the potential to replace standard power sources...
While damages due to ponding are common and expensive, provisions for design and
construction of flat roof systems lack guidance regarding these loads. The goal of this research is
to present methods of designing or building flat roofs that are less vulnerable to this condition. An
investigation of the literature,...
Foreign occupation and extraction have arguably existed since the very emergence of interstate conflict millennia ago. Yet despite humanity’s vast experience on the topic, we know surprisingly little about its long-term economic consequences. It is generally accepted by most that the extraction of resources by a foreign power tends to...
Variability in the terrigenous (land-derived) fraction of marine sediments,
including pollen and rock fragments, reflects the effects of regional climate change on
continentally derived runoff, ice extent, vegetation and ocean circulation. The transport of
this continental material to the seafloor must be understood in order to interpret the
terrigenous sediment...
The Curaçao Lava Formation (CLF) records the magmatic and tectonic processes that formed the Caribbean Large Igneous Province (CLIP). A model of the petrogenesis of the CLF was developed using new geochemical and geochronological data. These data include major element compositions obtained using X-ray fluorescence spectroscopy (XRF), trace element concentrations...
The purpose of this report is to detail the design and validation of a prototype robot that feeds biomass into a range of small household cookstoves at a programmable rate. Improved design and testing methods for the development of improved biomass cookstoves are needed to design stoves that alleviate the...
Graphs have a wide variety of real-world applications. In the area of social networks, graphs are composed of individuals and their relationships with others. Analysis of social networks led to the discovery of the small-world phenomena, which is also known as six degrees of separation. Our analysis is focused on...
High-resolution mass spectrometry was used to measure a range of volatile organic compounds (VOCs) in real time as they were produced by the ubiquitous marine cyanobacterium Synechococcus WH8102 during a 24-hour light/dark cycle. Ethenone, acetaldehyde, ethanol, isoprene, acetic acid, dimethyl sulfide (DMS), acetone, phenol, and several as-yet unidentified compounds were...
Industrial Engineering is a broad discipline, with a wide range of definitions for the field and the knowledge areas that make up its parts. A conceptual gap exists between the definition of the field of Industrial Engineering and the definitions of each of these parts. To facilitate advancement of the...
The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...
