Extracting Polar Anisotropy Parameters from Seismic Data
… for comparison; this procedure suppresses the anisotropy information in the real data. In this study, I tested a new method, using log data of Vp, Vs, and density, together with seismic pre-stack Common Depth Point (CDP) gathers near the well site, to deduce anisotropy parameters from them. …

Anisotropic analysis of unconventional reservoirs using rock physics model: Eagle Ford shale case study
… Ford shale in VTI media, I estimate the Thomsen parameters (i.e. anisotropy parameters). Anisotropy parameters epsilon, gamma and delta, on average, are 0.19, 0.29 and 0.04, respectively based on my modeling results in Eagle Ford shale. Anisotropic modeling results exhibit a good correlation with …

Electron Transport via Single Molecule Magnets with Magnetic Anisotropy
… due to the high spin and large magnetic anisotropy of iron(II). We explore the exchange coupling of iron atoms in two EMACs: [Fe2(mes)2(dpa)2] and [Fe4(tpda)3Cl2]. Chapter 1 provides an introduction to SMMs, electron transport experiments via SMMs and an introduction to density functional …

Interpretation of shear wave birefringence in P to S converted waves data using the propagator matrix method
… of interest and is accurate for estimating the anisotropy parameters. The method involves solving a non-linear problem in the frequency domain where Simulated Annealing is used as the global minimization technique. The procedure allows estimation of the propagator matrix related to the target …

Azimuthal P-wave AVA Inversion for Fracture Orientation and Density
… (GLI), for fracture orientation and HTI anisotropy parameters, were applied on P-wave reflection coefficients with variable incident angle and azimuth. However, 90˚ ambiguity in the estimation of the fracture orientation always exists. Sensitivity analysis of the inversion results, …

Exploring the Chemistry of Methoxide with Oxygen through Photoelectron Imaging Spectroscopy
In this dissertation, photoelectron imaging spectroscopy is employed to probe the gas-phase chemistry between methoxide (CH3O) and oxygen, including evidence of previously unexplored reaction paths and providing further insight into the fundamentals of chemical bonding. First, the known reaction …

Estimating Seismic Anisotropy: Fluid Substitution Theory, 3D-Printed Inclusion Models, and Multi-Component 3D VSP in the Bakken Shale
Understanding seismic anisotropy is one of the most important issues in seismic exploration. In this dissertation, I tried to understand how fluids and lithology influence the elastic properties and seismic anisotropy of rocks, theoretically, experimentally, and in the field. I derived anisotropic …

Geomechanics and elastic anisotropy of the Bakken Formation, Williston Basin
… rocks exhibit anisotropic characteristics. Anisotropy is particularly common in many sedimentary rocks, such as shales. Anisotropy is defined as the spatial alignment of mineral grains, layers, fractures and stresses which causes elastic wave velocity and other elastic properties to vary …

Two-particle correlation studies in heavy ion collisions at the Large Hadron Collider
… and <em>V</em>3 coefficient. The single-particle anisotropy parameters <em>v</em>2 and <em>v</em> 3 are extracted and normalized by their mid-rapidity value. The normalized <em>v</em>2(<em>η</em>cm)/<em>v</em> 2(<em>η</em>cm=-0.465) distribution as a function of the center-of-mass pseudorapidity …
