Validation of Design For Additive Manufacturing Heuristics for Aperiodic Structures through Application to Regular Structures

Creator:: Schipper, Paxton
Abstract:: Aperiodic structures cause significant challenges to subtractive manufacturing methods due to the common features such as inaccessible voids within the structure. Additive man- ufacturing presents an appealing alternative for this purpose. The aim of this research is to test analysis heuristics for validity through application to periodic structures. First, a...

Electrical Conductivity of Ceramic Material at High Temperature

Creator:: Kangsathein, Parm
Abstract:: The electrical conductivity data of ceramic material at high temperatures can be useful in the application of modeling, solid oxide fuel cell (SOFC), and magnetohydrodynamic (MHD). The existing data is considerably lacking at extreme temperatures. Our research focuses on bridging this gap by reporting the electrical conductivity measurements of sets...

TO PAY OR NOT TO PAY, THAT IS THE QUESTION

Creator:: Oster, Sidney C.
Abstract:: The “why” of any situation is one of the most important questions to ask. Inventors have ideas every day. Some ideas are the brilliant ideas that lead to a better tomorrow. To protect these ideas, inventors turn to patents, a governmental grant of the right to stop others, for a...

Mechanically Enhanced and Optically Compatible Hydrogels for Particle Image Velocimetry in Porous Flow

Creator:: Cornwell-Arquitt, Luke
Abstract:: Hydrogels have been attractive for use as a medium in porous flow studies, but have always been limited in this role because of their poor mechanical properties. This project analyzes and tests two recently developed hydrogels, poly(methacrylamide-co-methacrylic acid) (PMM), and a heat-treated long chain PVA hydrogel. Particle image velocimetry (PIV)...

Turning Brake Cylinder Housing

Creator:: Radcliffe, Noah
Abstract:: The purpose of this project is to assist the OSU Baja Racing vehicle in turning more sharply. This is done using a turning brake, which locks one rear wheel to facilitate turning on a smaller radius. This project focuses on the development of a custom cylinder housing for the turning...

The COVID-19 pandemic’s effect on outdoor recreation

Creator:: Davis, Jensen
Abstract:: In the spring of 2020, the COVID-19 pandemic began. This prompted quarantines, mask mandates, and stopped many businesses and services. This study asked the question of what people decided to do in terms of their recreation habits in response to the pandemic. We took a sample of Oregon State University...

Testing and design procedures for electric propellant pumps for suborbital bi-propellant rockets

Creator:: Verna-Ketel, Dominic
Abstract:: An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...

Fluid dynamic analysis of fluid flow in a raceway tank for cultivation of macrophytic red algae, Gracilaria vermiculophylla

Creator:: Willis, Myles
Abstract:: As new cost-effective cultivation methods are needed for macrophytic red algae, this experiment expands upon a previously studied land-based approach. The experiment aimed to determine how the fluid dynamics of a previously researched land-based method affected the growth of the macrophytic red alga, Gracilaria Vermiculophylla. A clonal culture of G....

Life cycle analysis of mass timber and reinforced concrete three-story structures

Creator:: Brown, David
Abstract:: With growing awareness of the negative impacts of the built environment, solutions for dramatic environmental, economic, and social improvements are sparking in all sectors, especially within the construction industry. The work of this thesis aims to quantify and compare social, economic, and environmental impacts of a three-story mass timber structure...

Design cycle models and knowledge management systems

Creator:: Popham, Kinsey
Abstract:: This thesis explores the relationship between design cycle models and knowledge management systems applied to various physical prototypes that the author developed from 2020 to 2023. The author walks through the process of prototyping a potty-training device in OSU’s Prototype Development Lab and an automated testing fixture for her Senior...

Systemic barriers encountered by Latinas in engineering

Creator:: Coto, Paula
Abstract:: Latinas in engineering face discrimination on the intersectionality of their two identities, Latinx and woman. The barriers that happen to them as an indirect effect of previous or existing institutional systems of oppression are called systemic barriers. Coming from the lens of four subjects, in a ranking of the barriers...

Development of a custom testbed to evaluate the efficacy of a force-amplifying implant in a live rabbit model

Creator:: Justen, Gabriella
Abstract:: In the United States, 58.7% of the spinal cord injuries that occur each year result in some degree of tetraplegia, this leads to reduced control of upper limb muscle. One surgery that can restore some upper limb function is a brachioradialis (BR) to flexor pollicis longus (FPL) tendon transfer surgery,...

Effects of nickel addition In Cu-Zr-Hf-Al metallic glass matrix

Creator:: Miska, John
Abstract:: Metallic glasses (also referred to as amorphous metals) have been gaining interest in the materials science community in recent years. These amorphous materials demonstrate promising properties compared to their crystalline counterparts that include much higher strength and elastic strain limit, better corrosion and wear resistance, superior soft magnetism, and an...

Mechanical Properties of Hemp Fiber Reinforced Polylactic Acid Composite

Creator:: Skuratowicz, Berkeley
Abstract:: This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of...

Analysis of Staged Hydraulic Air Compressors

Creator:: Shibley-Styer, Ian
Abstract:: To investigate the viability of staging hydraulic air compressors (HACs), a model for HACs operating with a closed loop water cycle powered by a pump was made. This model was used to simulate how these HACs would respond to variable heights and mass flow ratios for both single-stage and multi-stage...

Design and Fabrication of a Public Locker for Non-Motorized Watercraft

Creator:: Cordisco, Jonathan
Abstract:: Visitors to waterways need a way to securely lock up their non-motorized watercrafts to allow for exploration of the local area and communities. The Willamette Water Trail Steering committee recognized this problem and approached the Oregon State University Prototype Development lab to develop and fabricate a solution. The engineering design...

Part-Load Optimization of an Organic Rankine Cycle

Creator:: Ramsey, Owen
Abstract:: Waste-heat-recovery Organic Rankine Cycle (ORC) systems use excess heat from industrial processes to produce electrical power. In many cases, the temperatures and mass flow rates of these excess-heat streams vary significantly over time, causing the ORC to often operate far from its design point. In this study, a control strategy...
