Fluence based neutron balance approach using spatial flux calculations
(2015-08)This thesis describes the addition of spatially dependent power sharing to a methodology for calculating the input and output isotopics and burnup of nuclear reactors within a nuclear fuel cycle simulator. This methodology ... -
FLUENT models of furnace tubes and their use to guide geometric changes
(2007-05)A modified straight-through single-ended furnace tube is modeled in FLUENT. The modification was created in order to save on fuel and prolong the life of the tubes. The research described in this thesis is based on an ... -
Fluid and metal sourcing for the native silver deposits in the Batopilas Mining District, Chihuahua, Mexico
(2012-08)The Batopilas Mining District was a major silver producer, with estimated historic production of more than 300 million ounces. Orebodies consist of high-grade silver in the forms of native silver, acanthite and proustite ... -
Fluid and queueing networks with Gurvich-type routing
(2015-08)Queueing networks have applications in a wide range of domains, from call center management to telecommunication networks. Motivated by a healthcare application, in this dissertation, we analyze a class of queueing and ... -
Fluid and solid mechanics in the step and flash imprint lithography process
(2006)Step and Flash Imprint Lithography (SFIL) has become a promising technology to bring integrated circuit feature sizes to the nanometer scale. It is a molding process in which liquid monomer is imprinted by a patterned ... -
Fluid Characterization at the Cranfield CO₂ Injection Site : Quantitative Seismic Interpretation from Rock-Physics Modeling and Seismic Inversion
(2014-12)This dissertation focuses on quantitatively interpreting the elastic properties of the Cranfield reservoir for CO₂ saturation. In this work, quantitative interpretation starts by examining the relationship between CO₂ ... -
Fluid content effect on acoustic impedance and limits of direct detection capability : illustrated on an offshore prospect
(1980-12)The presence of gas and oil in some sand formations decreases the seismic velocity and density to such an extent that anomalously large reflections coefficients are encountered at fluid contacts. Geerstma and Gassmann's ... -
Fluid description of a magnetized toroidal plasma
(2007-12)A closed system of fluid equations to describe the evolution of a weakly collisional toroidal plasma is presented. The primary physical phenomena incorporated are gyration, guiding center motion, and parallel flows of ... -
Fluid description of relativistic, magnetized plasmas with anisotropy and heat flow : model construction and applications
(2009-08)Many astrophysical plasmas and some laboratory plasmas are relativistic: either the thermal speed or the local bulk flow in some frame approaches the speed of light. Often, such plasmas are magnetized in the sense that the ... -
The fluid dynamics of flagellar swimming by microorganisms and harmonic generation by reflecting internal, ocean-like waves
(2011-12)This dissertation includes two fluid dynamics studies that involve fluid flows on vastly different scales, and therefore vastly different physics. The first study is of bacterial swimming using a flagellum for propulsive ... -
Fluid flow during low-[delta]¹⁸O skarn formation : insights from Empire Mountain, Mineral King, Sierra Nevada
A two-dimensional numerical simulation of oxygen isotope transport in the shallow crust has been developed to examine the mechanisms of fluid flow during the formation of skarns. The Empire Mountain skarn in Mineral King, ... -
A fluid inclusion and cathodoluminescence approach to reconstruct fracture growth in the Triassic-Jurassic La Boca Formation, Northeastern Mexico
(2011-12)Opening-mode fracture shapes are typically the result of brittle deformation and proportional growth in fracture height, length, and width. Based on the typical fracture shape, it is assumed that fracture tips are free to ... -
Fluid inclusion studies of microfractures in Eriboll Formation, NW Scotland : insights into timing of fracture opening
(2012-05)The Cambrian Eriboll Formation exposed in the footwall of the Moine Thrust, NW Scotland, provides a suitable outcrop analog for naturally fractured tight-gas sandstone reservoirs. Previous studies distinguished five regional ... -
Fluid intelligence and the cerebellum in autism spectrum disorders
(2013-08)Executive functioning abilities, including abstract reasoning, are often reported as weaknesses in autism spectrum disorders (ASDs). The current study examines reasoning through a different approach by utilizing the ... -
Fluid management in immersion and imprint microlithography
(2010-12)The important roles of fluid dynamics in immersion lithography (IL) and step-and-flash imprint lithography (S FIL) are analyzed experimentally and theoretically. In IL there are many challenges with managing a fluid droplet ... -
Fluid models for Internet design and simulation
(2006)Over the past decade, fluid models have been widely used, and shown to be efficient and accurate in the modeling, analysis, and design of the Internet. In literature, much of this work has focused on the design of end-host ... -
Fluid reasoning, working memory and written expression of 9 to 14 year old children with attention deficit/hyperactivity disorder
(2007)Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent conditions among school children. Executive function deficits representing difficulties in maintaining an appropriate problem set for the attainment ... -
Fluid-based brush systems for novel digital media
(2015-12)Digital media allows artists to create a wealth of visually-interesting effects that are impossible in traditional media. This includes temporal effects, such as cinemagraph animations and expressive fluid effects. Yet ... -
Fluid-structure interactions in microstructures
(2013-05)Radio-frequency microelectromechanical systems (RF MEMS) are widely used for contact actuators and capacitive switches. These devices typically consist of a metallic membrane which is activated by a time-periodic electrostatic ... -
Fluorescence contrast agents and spectroscopy for the early detection of oral cancer
(2004)Despite advancements in treatment techniques, the five-year survival rate for oral cancer has not increased significantly over the past 40 years. This is likely due to the fact that oral cancer is generally not diagnosed ...
