Tomography Of The Darcy Velocity From Self-Potential Measurements, A. Jardani, A. Revil, A. Bolève, A. Crespy, J.-P. Dupont, W. Barrash, Bwalya Malama

Natural Resources Management and Environmental Sciences

An algorithm is developed to interpret self-potential (SP) data in terms of distribution of Darcy velocity of the ground water. The model is based on the proportionality existing between the streaming current density and the Darcy velocity. Because the inverse problem of current density determination from SP data is underdetermined, we use Tikhonov regularization with a smoothness constraint based on the differential Laplacian operator and a prior model. The regularization parameter is determined by the L-shape method. The distribution of the Darcy velocity depends on the localization and number of non-polarizing electrodes and information relative to the distribution of the …

Induction Of Classifiers From Multi-Labeled Examples: An Information-Retrieval Point Of View, Kanoksri Sarinnapakorn

Open Access Dissertations

An important task of information retrieval is to induce classifiers capable of categorizing text documents. The fact that the same document can simultaneously belong to two or more categories is referred by the term multi-label classification (or categorization). Domains of this kind have been encountered in diverse fields even outside information retrieval. This dissertation discusses one challenging aspect of text categorization: the documents (i.e., training examples) are characterized by an extremely large number of features. As a result, many existing machine learning techniques are in such domains prohibitively expensive. This dissertation seeks to reduce these costs significantly. The proposed scheme …

Target Space Duality With Dilaton And Tachyon Field, Blazej Ruszczycki

Open Access Dissertations

We study the target space duality of classical two dimensional sigma models. The models with dilaton and tachyon field are analyzed. As a motivating example the historical electric-magnetic duality is presented. We review the construction of the duality transformation and the integrability conditions for the nonlinear sigma models with target spaces described by general metrics and antisymmetric two-forms. We generalize the formalism for the models whose actions contain the dilaton and tachyon field. For the dilaton field case it is required that the duality is a property solely of the target manifolds, independent of the world-sheet geometry. For both cases …

A Quantitative Description Of The Interaction Of Enhancement And Depression Of Transmitter Release At The Neuromuscular Junction, Alice M. Holohean

Open Access Dissertations

Synaptic transmission alters the strength of the postsynaptic potential, through a process called short-term synaptic plasticity (STP). In this study, endplate potentials (EPPs) from the frog neuromuscular junction were used to resolve and quantify the presynaptic components involved in enhancement and depression of transmitter release during repetitive stimulation under normal quantal release conditions (2 mM Ca2+, 1mM Mg2+). During trains of stimulation given between 10 - 200 Hz, the amplitude of the EPPs first increased then decreased; a maximum increase of 77% was produced after 2-4 stimuli. EPP amplitudes began to increase at ~ 20 Hz, were maximal at ~ …

Analyses Of Dengue Fever And Aedes Aegypti (Diptera: Culicidae) Larval Habitats In A Tropical Urban Environment Of Costa Rica Using Geospatial And Mosquito Surveillance Technologies, Adriana Troyo

Open Access Dissertations

Dengue is currently the most important arboviral disease globally and is usually associated with built environments in tropical areas. Control measures are currently focused on community participation in control of the vector Aedes aegypti and larval source reduction. In Costa Rica, dengue fever is a relatively recent re-emerging disease and has become a serious public health problem. Remotely sensed information can facilitate the study of urban mosquito-borne diseases like dengue by providing multiple temporal and spatial resolutions appropriate to investigate urban structure and ecological characteristics associated with infectious disease. Initial studies showed that although dengue is a serious public health …

Sound Transmission Through A Fluctuating Ocean: A Modal Approach, Ilya A. Udovydchenkov

Open Access Dissertations

Sound transmission through a fluctuating deep ocean environment is considered. It is assumed that the environment consists of a range-independent background, on which a small-scale perturbation, due for example to internal waves, is superimposed. The modal description of underwater sound propagation is used extensively. The temporal spread of modal group arrivals in weakly range-dependent deep ocean environments is considered. The phrase "modal group arrival" refers to the contribution to a transient wavefield corresponding to a fixed mode number. It is shown that there are three contributions to modal group time spreads which combine approximately in quadrature. These are the reciprocal …

Development Of A Delivery System And Optical-Thermal Model For Laser Interstitial Thermotherapy Of Breast Tumors, Nelson Salas

Open Access Dissertations

The purpose of this project was to develop a delivery system optimized for laser interstitial thermotherapy of small tumors of the breast. The proposed approach is to combine laser interstitial thermotherapy with stereotactic imaging for fiber guidance and treatment monitoring. The goals of the dissertation were to design a fiber insertion system for cylindrical diffusing tip optical fibers and to derive optimal laser parameters for coagulation of 1 cm tumor plus a surrounding 1 cm thick rim of healthy tissue. A fiber insertion system compatible with a high resolution stereotactic digital X-ray biopsy system was designed to guide the fiber …

Natal Dispersal And New Group Formation In Capybaras (Hydrochoerus Hydrochaeris) In A Seasonally Flooded Savanna Of Venezuela, Elizabeth Rae Congdon

Dissertations

This study examines natal dispersal and new group formation in capybaras (Hydrochoerus hydrochaeris) in a seasonally flooded savanna in Venezuela. The first section describes a novel approach to the study of dispersal that could be applied to many taxa. Dispersal is considered in three stages (emigration, transience, and immigration) and its proximate and ultimate mechanisms are clearly differentiated. The second chapter describes dispersal behavior in capybaras, including which individuals disperse, when, and to where. In the third chapter, I evaluate dispersal in capybaras with respect to social subordination and social cohesion hypotheses. In this population, some support was …

Solution Structure Of Selenoprotein W And Nmr Analysis Of Its Interaction With 14-3-3 Proteins, Finn L. Aachmann, Dmitri E. Fomenko, Alice Soragni, Vadim N. Gladyshev, Alexander Dikiy

Vadim Gladyshev Publications

Selenium is a trace element with significant biomedical potential. It is essential in mammals due to its occurrence in several proteins in the form of selenocysteine (Sec). One of the most abundant mamma¬lian Sec-containing proteins is selenoprotein W (SelW). This protein of unknown function has a broad expression pattern and contains a candidate CXXU (where U represents Sec) redox motif. Here, we re¬port the solution structure of the Sec¹³ →Cys variant of mouse SelW determined through high resolution NMR spectroscopy. The protein has a thioredoxin-like fold with the CXXU motif located in an exposed loop similarly to the redox-active …

Orange County Convention Center Energy Analysis And Energy Information System, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

The Orange County Convention Center (OCCC) has the 2nd largest convention facility utilization in the nation. Two primary buildings provide about seven million square feet of conditioned space to approximately 1.5 million visitors per year. In efforts to reduce energy conservation, OCCC began implementing several energy conservation measures beginning in 2005 and continuing over the last 2 years with plans to continue additional efforts in the future. An analysis of monthly chilled water and electricity used by the West and North/South Buildings has been completed in an effort to investigate reductions in energy use resulting from conservation measures. This final …
