Identifying Threshold Values of Accelerometer-Determined Moderate-to-Vigorous Physical Activity that Correspond to Self-Reported Compliance to the 2008 Physical Activity Guidelines for Americans : National Health and Nutrition Examination Survey 2003-2006

Creator:: Brier, Julie A.
Abstract:: Current public health guidelines for physical activity (PA) were primarily formulated using evidence collected from a series of prospective cohort epidemiological investigations that measured self-reported PA. In light of this observation, and the known discordance between self-reported and objectively-monitored PA, it remains common for researchers to assess compliance to current...

Role of Stoichiometry on Ordering in Ni-Cr Alloys

Creator:: Teng, Fei
Abstract:: Mechanical property degradation due to isothermal ageing is of potential concern for alloys based on the Ni-Cr binary system (e.g., Inconel 690, 625), particularly in nuclear power applications where component lifetimes can exceed 40 years. In the present research, the disorder-order phase transformation, which is the primary mechanism of ageing,...

Heat treatment effects on CPM-M4 tool steel performance as edged blade material

Creator:: Lian, Sidi
Abstract:: CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...

Microstructural Characterization of Porosity in U-Mo Low Enriched Uranium Plate Fuel

Creator:: Westman, Bjorn E.
Abstract:: New low enriched uranium (LEU) fuels are being developed for replacement of high enriched uranium (HEU) fuels in high power research reactors. U-Mo LEU plate fuels have been identified as a candidate for replacement of current HEU fuels. However, U-Mo fuels tend to exhibit accelerated swelling typically at fission densities...

Corrosion of Carbon and Stainless Steels in H₂O-sCO₂ Environments for Power Cycle Applications

Creator:: Teeter, Lucas
Abstract:: The corrosion behaviors of carbon and stainless steels were investigated in supercritical CO₂ (sCO₂ ) containing H₂O and O₂ simulating conditions that exist in direct sCO₂ power cycle heat exchangers. Thermodynamic properties of CO₂-H₂O-O₂ systems related to the corrosion phenomena were determined using NIST software. The exposure tests of the...

Corrosion Resistance of Alloys in Seawater and Supercritical Carbon Dioxide Environments

Creator:: Repukaiti, Reyixiati
Abstract:: The corrosion resistances of several alloys were investigated to optimize performance and cost in seawater and supercritical CO2 environments. Many alloys are prone to corrosion in seawater and/or supercritical CO2 containing impurity environments. Exposure and electrochemical experiments were conducted in both environments to evaluate alloys’ corrosion resistance. In seawater corrosion...

Terrain-Aware Probabilistic Search Planning for Unmanned Aerial Vehicles

Creator:: Schomer, Nathan L.
Abstract:: Mountain search and rescue is a vital form of emergency response to assist people in austere environments (e.g., extreme terrain, poor weather). Volunteer mountain search and rescue teams in the United States have begun adopting consumer- grade unmanned aerial vehicles to assist a variety of tasks (e.g., search, resource delivery);...

Artificial Swarm Control Through Learning Based Leadership

Creator:: Tuzel, Ovunc
Abstract:: Collective migration in animal groups is often guided by distributed leader agents that influence their peers by modulating their motion behaviors. Distributed leadership is a promising navigation strategy for artificial swarms, but designing the leaders’ controllers is difficult due to the swarm’s collective emergent behaviors. The presented research formulates a...

Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

Creator:: Evered, Cole E.
Abstract:: This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...
