Classical chaotic scatting from symmetric four hill potentials

Creator:: Bauman, Jordan Michael
Abstract:: Classical chaotic scattering experiments were performed on ten different four hill potentials, unique under x-axis reflection, given by: V(x,y) = x²y²e⁻⁽ˣ² ⁺ ʸ²⁾ σᵢ where σᵢ was ±1 depending upon quadrant. Our work was based on a paper (9) that only studied the case where σᵢ =1 in all quadrants....

The effect of ultra-high pressure on the emf of thermocouples

Creator:: Eide, Stuart Ames
Abstract:: The effect of ultra-high pressure on the thermal emf of a chromelialumel thermocouple is investigated using an indirect method which does not require a direct knowledge of the temperature of the pressurized junction. The unknown temperature is written parametrically as a function of a directly measured quantity, the electrical power...

The dynamics of oxygen vacancies in zirconia : an analysis Of PAC data

Creator:: Alves, Mauro A.
Abstract:: Nuclear techniques such as perturbed angular correlation (PAC) sample the hyperfine interactions of a large number of probe atoms in specific crystallographic sites. Real crystals contain static defects producing a distribution of electric field gradients (EFGs) that add to the ideal EFG of the crystal at any given probe site....

X-ray Emissions in Measurements of the Neutron Capture Cross Sections for the Production of ¹⁹⁷Hg and ¹⁹⁷Pt and Scoping the Science Parameter Space of Future X-ray Astrophysics Calorimeter Missions

Creator:: Keck, Mason L.
Abstract:: A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the 77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of ¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...

Electronic structures and magnetic properties of iron in various magnetic states and structural phases

Creator:: Peng, Songshi S.
Abstract:: Total energy calculations based on density functional theory are generally a good approach to obtain the properties of solids. The local density approximation (LDA) is widely used for calculating the ground state properties of electronic systems; for excited states the errors are in general unknown. The important aspects of LDA...

A study of actinide de-excitation through neutron emission from the deuteron induced fission of ²³⁸U

Creator:: Sprunger, Peter Hayden
Abstract:: The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...

Multicellular monolayer’s self-organization under external stimuli

Creator:: Li, Guanyu
Abstract:: Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...
