Abstract:
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling. The present status of theoretical solar models is presented and discussed in relation with the observational constraints: helioseismology, lithium depletion and measured neutrino fluxes.

Abstract:

In the past three decades, spintronic devices have played an important technological role. Half-metallic alloys have drawn much attention due to their special properties and promised spintronic applications. This dissertation describes some theoretical techniques used in first-principal calculations of alloys that may be useful for spintronic device applications with an emphasis on half-metallic ferromagnets. I consider three types of simple spintronic materials using a wide range of theoretical techniques. They are (a) transition metal based half-Heusler alloys, like CrMnSb, where the ordering of the two transition metal elements within the unit cell can cause the material to be ferromagnetic semiconductors or semiconductors with zero net magnetic moment, (b) half-Heusler alloys involving Li, like LiMnSi, where the Li stabilizes the structure and increases the magnetic moment of zinc blende half-metals by one Bohr magneton per formula unit, and (c) zinc blende alloys, like CrAs, where many-body techniques improve the fundamental gap by considering the physical effects of the local field. Also, I provide a survey of the theoretical models and numerical methods used to treat the above systems.

Full text
Abstract:
The chemistry of actinides in aqueous solution is important, and it is essential to build adequate conceptual models and develop methods applicable for actinide systems. The complex electronic structure makes benchmarking necessary. In the thesis a prototype reaction of the water exchange reaction for uranyl(VI), for both ground and luminescent states, described with a six-water model, was used to study the applicability of density functional methods on actinides and different solvation models. An excellent agreement between the wave function methods CCSD(T) and MP2 was obtained in the ground state, implying that near-minimal CASPT2 can be used with confidence for the reaction in the luminescent state of uranyl(VI), while density functionals are not suited to describe energetics for this type of reaction. There was an ambiguity concerning the position of the waters in the second hydration sphere. This issue was resolved by investigating a larger model, and prop- erly used the six-water model was found to adequately describe the water exchange reaction. The effect of solvation was investigated by comparing the results from conductor-like polarizable continuum models using two cavity models. Scattered numbers made it difficult to determine which solvation model to use. The final conclusion was that the water exchange reaction in the luminescent state of uranyl(VI) should be addressed with near-minimal CASPT2 and a solvation model without explicit cavities for hydrogens. Finally it was shown that no new chemistry appears in the luminescent state for this reaction. The thesis includes a methodological investigation of a multi-reference density functional method based on a range separation of the two-electron interaction. The method depends on a universal parameter, which has been determined for lighter elements. It is shown here that the same parameter could be used for actinides, a prerequisite for further development of the method. The results are in that sense promising.

Abstract:
Cette thèse inclut quatre chapitres réunis autour d'un thème commun: les problèmes inverses dans les jeux stochastiques en information incomplète. L'objectif de cette thèse est d'étudier l'identification et l'estimation d'un paramètre fonctionnel dans le contexte des variables inobservables, situation courante dès qu'il y a une asymétrie d'information. On cherche à retrouver la distribution des primitives dans des modèles d'enchères et de la théorie des contrats à partir des variables observées et du concept d'équilibre "Bayesian Nash Equilibrium". La méthodologie d'identification et d'estimation dans tous les quatre essais est basée sur une réécriture du modèle économique en termes de quantiles et l'analyse économétrique est conduite entièrement dans un contexte non paramétrique. Néanmoins, pour une certaine classe de problèmes que l'on appelle "problèmes bien-posés", la vitesse de convergence de nos estimateurs est une vitesse paramétrique. En général, les modèles de la théorie des jeux mènent souvent à des problèmes inverses non-linéaires mal-posés. Cependant, les deux premiers essais de cette thèse traitent des exemples des problèmes inverses bien-posés (l'enchère au troisième prix et le modèle d'anti-sélection). Le troisième essai est une généralisation de la méthodologie proposée dans les deux premiers articles et introduit une nouvelle classe de problèmes bien-posés que l'on appelle "hazard-rate game models". Le dernier article étudie l'enchère au premier prix en utilisant l'approche par les quantiles ce qui permet d'obtenir, par opposition avec la littérature existante, une forme explicite pour la fonction des quantiles des variables latentes
This thesis consists of four essays articulated around the topic of inverse problems in games of incomplete information. The objective of the dissertation is to study the identification and the estimation of a functional parameter in a context of unobserved variables, situation often encountered in the presence of asymmetric information. We recover the distribution of primitives in auctions and contract-theory models using the data and the concept of Bayesian Nash Equilibrium. All chapters use a quantile approach both in terms of identification and estimation methodology. Another common feature is that all the economic issues are studied in a fully nonparametric setting. In spite of that, for a class of problems that turn out to be well-posed inverse problems, we find parametric speed of convergence for our estimators. Usually, many game-theoretical models belong to a class of ill-posed inverse problems. Nevertheless, the two first papers (the third-price auction model and the pure adverse selection model) of this thesis treat models that belong in fact to a class of well-posed inverse problems. The third essay generalizes the results of the first two articles by considering a general form for the strategy function of the game and introduces a new class of well-posed games called "hazard-rate game models". The last chapter of the dissertation studies the first-price auction model using the quantile approach which, by contrast with the existing literature, leads to a closed-form solution for the quantiles of the latent variables

Arciero, Julia. "Theoretical Models of Blood Flow Regulation." Diss., The University of Arizona, 2008. http://hdl.handle.net/10150/195903.

Full text
Abstract:
In normal tissues, blood supply is closely matched to tissue demand for wide ranges of oxygen demand and arterial pressure. This suggests that multiple mechanisms regulate blood flow. Theoretical models can be used to analyze these interacting mechanisms. One proposed mechanism for metabolic flow regulation involves the saturation-dependent release of ATP by red blood cells, which triggers an upstream conducted response signal and arteriolar vasodilation. To analyze this mechanism, oxygen and ATP levels are calculated along a flow pathway of seven representative segments, including two vasoactive arteriolar segments. The conducted response signal is dependent on ATP concentration. Arteriolar tone depends on the conducted response signal, local wall shear stress and wall tension. Arteriolar diameters are calculated based on vascular smooth muscle mechanics. The model can account for increases in perfusion consistent with experimental findings at low and moderate oxygen consumption rates despite the opposing effects of the myogenic and shear-dependent responses. Autoregulation, the maintenance of nearly constant blood flow as arterial pressure varies, is assessed in the presence or absence of the myogenic, shear-dependent and/or metabolic responses. The model results indicate that the combined effects of myogenic and metabolic regulation overcome the vasodilatory effect of the shear-dependent response to generate autoregulatory behavior. Capillary recruitment has been shown to increase the capacity for oxygen delivery during exercise. In the model, capillary density is assumed to depend on small arteriole diameter. The model predicts a significant increase in the range over which perfusion can be regulated when recruitment is included. Oscillations in diameter and tone are predicted under certain conditions, suggesting a novel mechanism for vasomotion. The conditions that give rise to oscillations are analyzed. It is shown that the appearance of oscillations depends in a complex way on a number of system parameters. In summary, the theoretical model provides a quantitative assessment of the myogenic, shear-dependent and metabolic responses that affect blood flow regulation and identifies a role for capillary recruitment and vasomotion in the control of blood flow.

Full text
Abstract:
In this thesis, we study the effects of weak compressibility on staggered vortex streets, which are a ubiquitous phenomenon observed in nature. They are formed by fluid flowing past an obstacle, and can be found at several different length scales ranging from human length scales such as in water flowing under a bridge, to astronomical length scales such as planetary atmospheres, and beyond. They are of fundamental importance in fluid flows of interest to engineers and applied mathematicians alike. Yet, these vortex streets have not been studied as much theoretically. The classical exact solutions of Kármán are more than a century old, and used singular vortex models. The studies by Saffman and co-workers considered a vortex patch street, thus removing the singularity, however this study was numerical. Part of the difficulty in de-singularised models arises because of the unknown shape of the free-boundary of a finite-sized vortex. In particular, the effects of compressibility have not been taken into account in any theoretical investigation from first principles. We undertake a theoretical study of weakly compressible vortex streets, and obtain solutions to first-order for the velocity field. The vortices are modelled as hollow vortices, which are bounded regions of constant pressure with a non-zero circulation around them. For incompressible hollow vortex streets, exact solutions based on a conformal mapping approach were found by Crowdy and Green (2011). We perform a Rayleigh-Jansen (perturbation) analysis on these solutions, assuming isentropic flow of an ideal gas. We develop a novel method involving a rare use of complex analysis in studying compressible flows of this type. We utilise the Imai-Lamla formula [Imai (1942)] for the complex potential, which reduces the solution of the weakly compressible flow to computing analytic functions. Combining this with a conformal mapping approach, we solve the free-boundary problem by obtaining boundary value problems in multiply-connected pre-image domains (an annulus), which are solved through modern applications of classical methods. We utilise the machinery of the Schottky-Klein prime function for this domain, which helps in solving the boundary value problems for the analytic functions. We find that the speed of the vortex street changes due to compressibility, but the details of this change depends importantly on the area of the vortices. The vortex street is found to speed up for smaller areas and slow down at larger areas. The critical area of transition is found to be further dependant on the vortex configuration in the flow. We discuss the relationship of the present results with a few other known results in the context of different flows. We compare our results in the zero vortex size limit, to the results from a weakly compressible point vortex analysis undertaken in Crowdy and Krishnamurthy (2017b) and find agreement. Parts of the results in this thesis are reported as a paper Crowdy and Krishnamurthy (2017a). It is hoped that the present study leads to further studies on related problems such as the stability of vortex streets and vortex wake modelling for both incompressible and compressible flows. Other related problems likely to be influenced by this study include the free compressible vortex pair, which is important from the point-of-view of the theory of vortex sound.

Abstract:
This chapter reviews the literature applying health behavior theories to indoor tanning. Few studies have tried to fit full versions of health behavior models to indoor tanning. Theoretical models from the family of theories referred to as the reasoned action approach (e.g., theory of planned behavior, behavioral alternative model, prototype willingness model, etc.) have been most commonly used to study indoor tanning. Results indicate that these models fit indoor tanning data moderately to extremely well. Two lesser known models, problem behavior theory and the terror management health model, have also demonstrated a reasonable fit. Two other common models, the health belief model and social cognitive theory, have never been fully tested with indoor tanning. However, key constructs from these models (e.g., perceived susceptibility and threat, modeling) have been used to understand indoor tanning. Empirical research conducted represents a solid start toward developing strong, comprehensive models of indoor tanning that can guide intervention efforts. This initial work needs to be expanded by conducting longitudinal studies and by including a broader age range in studies because the majority of existing work has focused on young adults. Incorporating findings related to tanning dependency, peer group affiliation, media influences and other constructs into these foundational models will also improve our understanding and ability to develop efficacious interventions to reduce engagement in this health risk behavior.

Photo induced spectral changes of some molecules containing electronic π systems are investigated and the effect of electrocyclic reactions (ring closure etc) on their electronic structure is considered. Two types of molecules are studied 1) Molecules which exhibit two stable states characterized by different π electron configurations1) such as 2) electron transfer systems containing a "π electron bridge" linking donor and acceptor which can be modified by a photo induced reaction for example Static electronic π systems are described by a nearest neighbor Huckel Theory, i.e. by a Hamiltonian of the type where ai+, ai are the usual Fermion creation and destruction operators, ε the p electron energy and Γij the coupling between nearest neighbor p orbitals. Due to rotation of molecular fragments Γij depends on the orientation of the relevant p orbitals.

Abstract:
Models that predict distributions of species by combining known occurrence records with digital layers of environmental variables have much potential for application in conservation. Through using this module, teachers will enable students to develop species distribution models, to apply the models across a series of analyses, and to interpret predictions accurately. In addition to its original components, this module features an updated and condensed synthesis document ("A Brief Introduction to Species Distribution Modeling for Conservation Educators and Practitioners," which provides theoretical and practical guidance for the expanding field of species distribution modeling. The synthesis is supplemented by a new exercise where learners create and optimize species distribution models using Wallace, an R-based GUI (Graphical User Interface) application for ecological modeling that currently focuses on building, evaluating, and visualizing models of species niches and distributions. Additionally, there are four new PowerPoint presentations on species distribution models (the history and theory, data and algorithms, and evaluating SDMs), as well as a presentation on how to use Wallace. The original Synthesis, "Species' Distribution Modeling for Conservation Educators and Practitioners," introduces learners to the modeling approach, outlines key concepts and terminology, and describes questions that may be addressed using the approach. A theoretical framework that is fundamental to ensuring that students understand the uses and limitations of the models is then described. Additionally, it details the main steps in building and testing a distribution model, and describes three case studies that illustrate applications of the models. This module is targeted at a level suitable for teaching graduate students and conservation professionals.

Abstract:
Water vapor sorption is a fundamental characteristic of wood as a building material. Apart from empirical prediction, models are often used to interpret the time-dependent process of water vapor uptake (sorption kinetics) and equilibrium states of water in wood (sorption isotherms). This paper summarizes our recent investigations into measurement methods and popular models that are widely used for interpreting these physical phenomena. Commonly used criteria for determining equilibrium moisture content with the dynamic vapor sorption technique yield much larger errors than previously thought. A more rigorous equilibrium criterion and a method to reduce data acquisition time are proposed. Evaluation of the parallel exponential kinetics model with improved data and multi-exponential decay analysis indicates that this model is unable to characterize the full sorption kinetic response following a step change in relative humidity. Fitting of common sorption isotherm models to high-quality equilibrium data for wood gives model predicted physical quantities such as monolayer capacity and enthalpy of sorption that are far from agreement with independently measured data. Thus, these models are not valid for water vapor sorption in wood. New theoretical models are needed that correctly describe the physical phenomena.
