Low-frequency Teleseismic and Infrasound Arrivals along the Dense Corvallis Nodal Array

Creator:: Way, Rachel
Abstract:: The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...

Characterization of the Small-Strain Stiffness of Soils at an In-situ Liquefaction Test Site

Creator:: Donaldson, Aleyna M.
Abstract:: Strong ground motions from earthquakes can result in the reduction of the shear modulus and wave propagation characteristics of soils, and can produce liquefaction and cyclic softening during shaking and for some time following the seismic event. While the ground motions produced from controlled blasting are different than those in...

Groundwater Flooding and Guerrilla Trenches : a Participatory Approach for Flood Control

Creator:: Kemper, Joseph B.
Abstract:: Residents in South Falls City, a small town in the foothills of Oregon's Coast Range, battle intense flooding during the rainy season. Disagreements about surface water management pit neighbor against neighbor, but preliminary evidence suggests that groundwater flooding is an underlying cause. OSU researchers pair the emerging literature on groundwater...

Dextral shear and north-directed crustal shortening defines the transition between extensional and contractional provinces in north-central Oregon

Creator:: Johnson, Ajeet K.
Abstract:: Distributed deformation in the backarc of Cascadia is complex. Off the west coast lies the Cascadia convergent margin. East of the plate boundary, clockwise rotation of the Oregon Coast Range block with respect to stable North America influences backarc deformation, causing extensional faults in southeast Oregon, contraction folding in southeast...

Application of Motion Capture Technologies to Assess the Free Surface and Track Waterborne Debris in Wave Research Laboratories

Creator:: Shultz, Jamie
Abstract:: In coastal and ocean engineering, understanding the ocean environment and the forces from waves, tsunamis and waterborne debris on structures and floating bodies is an important aspect of designing safe and effective infrastructure. Understanding the impact of these forces on structures becomes an important question in the design process. Answering...

5th-Order Elliptic LPF Using Passive Charge Compensation Technique (PCC) Design

Creator:: Tsai, Cheng H.
Abstract:: The passive charge compensation (PCC) technique was introduced for switched capacitor (SC) circuit to increase the slew rate and enhance the linearity performance, as PCC techniques are used on the Delta-Sigma modulator (DSM) in ADC circuitry. The PCC technique of the project was applied to the design of a SC...

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

Effects of Moisture Intrusion on the Performance of a Cross-Laminated Timber (CLT) Angle Bracket Connection

Creator:: Bora, Shrenik S.
Abstract:: Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...

Heat Flow from a Vapor-Dominated Sublacustrine Vent Field Beneath Yellowstone Lake

Creator:: Favorito, Julia E.
Abstract:: Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...

Establishing new markets for CLT - lessons learned

Creator:: Schwarzmann, Gabriel
Abstract:: CLT is becoming global. New countries and regions increasingly realize the potential of what can be done with CLT. As a result, new markets are forming and new companies are entering the industry. Every new region or country that opens its doors to CLT has its own challenges and opportunities....
