Modernized Approach For Generating Micro-Layering And Macro-Heterogeneous Structures In Porous Media For Use In Transmitted-Light Method Flow Visualization Experiments, Aaron A. Jones
Electronic Theses and Dissertations
Image capturing in flow experiments has been used for fluid mechanics research since the early 1970s. Interactions of fluid flow between the vadose zone and permanent water table are of great interest to researchers because this zone is responsible for all recharge waters, pollutant transport and even irrigation efficiency for agriculture. Griffith, et al. (2011) developed an approach where constructed reproducible “geologically realistic” sand configurations are deposited in sand-filled experimental chambers or cells for light-transmitted flow visualization experiments. This method creates reproducible, reverse graded, layered (stratified) thin-slab sand chambers for visualizing multiphase flow through porous media. Reverse-graded stratification of sand …
Generalized Characteristics Of A Generic Polytope, Tommy Naugle
Generalized Characteristics Of A Generic Polytope, Tommy Naugle
Electronic Theses and Dissertations
For a smooth hypersurface S ⊂ R 2n given by the level set of a Hamiltonian function H, a symplectic form ω on R2n induces a vector field XH which flows tangent to S. By the nondegeneracy of ω, there exists a distinguished line bundle LS whose characteristics are the integral curves of XH. When S is the boundary of a smooth convex domain K˜ ⊂ R 2n, then the least action among closed characteristics of LS is equal to the Ekeland-Hofer-Zehnder capacity, a symplectic invariant. From a result due to Artstein-Avidan and Ostrover, there exists a continuous extension of …

Characterizing Variable Flow Pathways And Geochemical History Of Seepage Under The Mississippi River Levee: 2011, 2015, And 2016 Floods, Kaitlin Marie Voll
Characterizing Variable Flow Pathways And Geochemical History Of Seepage Under The Mississippi River Levee: 2011, 2015, And 2016 Floods, Kaitlin Marie Voll
Electronic Theses and Dissertations
Seepage beneath levees during flood stage becomes a concern when piping occurs, creating channels beneath the levee and forming sand boils where transported sediments discharge. Along the lower Mississippi River, pathways beneath the levee vary with surface geology, following deeper paths where the levee overlies channel fill deposits, and shallower paths where it overlies sand bar deposits. A preliminary investigation north of Vicksburg, MS, during the 2011 flood, demonstrated the potential for using aqueous geochemistry to differentiate sand boils forming at the end of deep and shallow flow pathways, though the study was limited to cation and trace metal analyses. …
Synthesis And Evaluation Of Dual-Acting Ligands For Mu Opioid And Neuropeptide Ff Receptors, Kelsey Gabrielle Mcpherson
Synthesis And Evaluation Of Dual-Acting Ligands For Mu Opioid And Neuropeptide Ff Receptors, Kelsey Gabrielle Mcpherson
Electronic Theses and Dissertations
Pain, although subjective, is an unpleasant sensation caused by a noxious stimulus, that effects millions of people every year. Currently, the most frequently prescribed class of analgesics for moderate to severe acute and sometime chronic pain are opioid analgesics, most commonly ?-opioid receptor (MOP) agonists, such as oxycodone, morphine, and fentanyl. Although these drugs provide significant pain relief, they are also associated with unwelcome side effects such as constipation, addiction, physical dependence, respiratory depression, and physiological tolerance that leads to hyperalgesia. Receptor desensitization due to excessive receptor activation by an agonist is but one source of physiological tolerance; it can …
Building An Autonomous Indoor Drone System, Hunter Gossett
Building An Autonomous Indoor Drone System, Hunter Gossett
Electronic Theses and Dissertations
This thesis presents an indoor autonomous drone system using a self assembled drone which uses a companion computer as well as external sensors for autonomous flight. While autonomous drone systems have been around for some time, originating with the military, the vast majority of them are designed for outdoor use, because of their heavy reliance on GPS for their positioning systems. In order to achieve autonomous flight indoors we choose to use simultaneous localization and mapping (slam) as our positioning system. The contributions of this thesis is an in depth guide to the hardware and assembly of a drone system, …

A Study Of Computational Problems In Computational Biology And Social Networks: Cancer Informatics And Cascade Modelling, Christopher Ma
Electronic Theses and Dissertations
It is undoubtedly that everything in this world is related and nothing independently exists. Entities interact together to form groups, resulting in many complex networks. Examples involve functional regulation models of proteins in biology, communities of people within social network. Since complex networks are ubiquitous in daily life, network learning had been gaining momentum in a variety of discipline like computer science, economics and biology. This call for new technique in exploring the structure as well as the interactions of network since it provides insight in understanding how the network works and deepening our knowledge of the subject in hand. …
Bases In Spaces Of Regular Multilinear Operators And Homogeneous Polynomials On Banach Lattices, Khazhak Varazdat Navoyan
Bases In Spaces Of Regular Multilinear Operators And Homogeneous Polynomials On Banach Lattices, Khazhak Varazdat Navoyan
Electronic Theses and Dissertations
For Banach lattices E1,…, Em and F with 1-unconditional bases, we show that the monomial sequence forms a 1-unconditional basis of Lr(E1,…, Em;F), the Banach lattice of all regular m-linear operators from E1×···× Em to F, if and only if each basis of E1,…,Em is shrinking and every positive m-linear operator from E 1×···×Em to F is weakly sequentially continuous. As a consequence, we obtain necessary and sufficient conditions for which the m-fold Fremlin projective tensor product E1⊗ |π|··· ⊗|π|E m (resp. the m-fold positive injective tensor product E1⊗|ϵ|··· ⊗ |ϵ|Em) has a shrinking basis or a boundedly complete basis. …
The Beam Dynamics And Beam Related Uncertainties In Fermilab Muon G-2 Experiment, Wanwei Wu
The Beam Dynamics And Beam Related Uncertainties In Fermilab Muon G-2 Experiment, Wanwei Wu
Electronic Theses and Dissertations
The anomaly of the muon magnetic moment, aμ ≡ (g-2)/2, has played an important role in constraining physics beyond the Standard Model for many years. Currently, the Standard Model prediction for aμ is accurate to 0.42 parts per million (ppm). The most recent muon g-2 experiment was done at Brookhaven National Laboratory (BNL) and determined aμ to 0.54 ppm, with a central value that differs from the Standard Model prediction by 3.3-3.6 standard deviations and provides a strong hint of new physics. The Fermilab Muon g-2 Experiment has a goal to measure aμ to unprecedented precision: 0.14 ppm, which could …
