An analysis was conducted to determine the behavior of a high pressure electric arc discharge inside the Plasmatron Fuel Reformer. The Plasmatron Fuel Reformer uses an electric arc to partially combust fuel in an internal combustion engine to increase efficiency and reduce emissions. Solutions of the conservation equations for the arc yield temperature, pressure and velocity profiles for arcs with 0.2-0.8 A currents. Acquired knowledge was used to predict arc radius and power delivered by the arc as a function of current.

Texto completoThe CERN WA97 results display a strong strangeness enhancement at mid-rapidity which is dependent on the strangeness of the particle concernec, and saturates at values of participating nucleons greater than 120. These results are phenomenologically described by the mixed canonical ensemble, with canonical (exact) strangeness conservation involving all strange resonances, and grand canonical conservation of charge and baryon number. It is shown that the data are well described by an equilibrium hadron gas. Other explanations of these data are reviewed.

Texto completoO objetivo desta investigação é avaliar o impacto das assunções dos modelos geradores de retornos nas fronteira eficiente e seus portafolios. Isto foi conseguido mediante o trabalho in-sample (assim eliminando o risco de estimação, focando a investigação no risco de modelo) em ambos mercados de ativos financeiros, o Europeo e Americano, nos 7 anos anteriores, considerando ambos, o caso em que shortselling esta permitido como também o caso em que esta proibido. O processo inclui o calculo da fronteira eficiente seguindo as assunções dos modelos geradores de retornos. Em particular o Constant Correlation Model (CCM), o Single-Index Model (SIM) e o modelo de tres factores de Fama e French (1993) Multi-Factor Model (MFM). Para os dois mercados de investimentos, comparamos a fronteira eficiente gerada aplicando MVT nos dados in-sample com a fronteira eficiente dos modelos de retorno seleccionados. Mostramos que o risco do model è importante na aplicação do MVT. Sendo os erros encontrados em todos os modelos consideravel. Também, considerando o risco de modelo para o caso de shortselling proibido, o CCM mostra melhor desempenho que os modelos mais sofisticados. Por outra parte, em condiçoes de shortselling permitido, o SIM mostra melhor desempenho.
The objective of this research is evaluating the impact of the return generating models assumptions in the efficient frontier and its portfolios. This is accomplished by working with in-sample data (eliminating the estimation risk and focus on the model risk) looking at both the European and American stock markets for the past 7 years, and considering both, the case when shortselling is allowed and the case when it is forbidden. The process includes the calculation of efficient frontier under the assumptions of return generating models. In particular, we look at the Constant Correlation Model (CCM), the Single-Index Model (SIM) and the three factors Fama and French (1993) Multi-Factor Model (MFM). For both markets we compared the true efficient frontier generated from the in-sample MVT with the corresponding efficient frontiers from the return generating models. We show model risk is an important issue when applying MVT. The errors in all model are considerable. In addition, considering model risk for cases when the short-sell is not allowed, the CCM is more accurate than more sophisticated models. On the other hand, under conditions of short-sell allowed, the SIM seams to be more accurate.

Texto completoThis dissertation consists of three independent essays in applied microeconomics and econometrics. Essay 1 investigates the issue why individuals with health insurance use more health care. One obvious reason is that health care is cheaper for the insured. But additionally, having insurance can encourage unhealthy behavior via moral hazard. The effect of health insurance on medical utilization has been extensively studied; however, previous work has mostly ignored the effect of insurance on behavior and how that in turn affects medical utilization. This essay examines these distinct effects. The increased medical utilization due to reduced prices may help the insured maintain good health, while that due to increased unhealthy behavior does not, so distinguishing these two effects has important policy implications. A two-period dynamic forward-looking model is constructed to derive the structural causal relationships among the decision to buy insurance, health behaviors (drinking, smoking, and exercise), and medical utilization. The model shows how exogenous changes in insurance prices and past behaviors can identify the direct and indirect effects of insurance on medical utilization. An empirical analysis also distinguishes between intensive and extensive margins (e.g., changes in the number of drinkers vs. the amount of alcohol consumed) of the insurance effect, which turns out to be empirically important. Health insurance is found to encourage less healthy behavior, particularly heavy drinking, but this does not yield a short term perceptible increase in doctor or hospital visits. The effects of health insurance are primarily found at the intensive margin, e.g., health insurance may not cause a non-drinker to take up drinking, while it encourages a heavy drinker to drink even more. These results suggest that to counteract behavioral moral hazard, health insurance should be coupled with incentives that target individuals who currently engage in unhealthy behaviors, such as heavy drinkers. Essay 2 examines the effect of repeating kindergarten on the retained children's academic performance. Although most existing research concludes that grade retention generates no benefits for retainees' later academic performance, holding low achieving children back has been a popular practice for decades. Drawing on a recently collected nationally representative data set in the US, this paper estimates the causal effect of kindergarten retention on the retained children's later academic performance. Since children are observed being held back only when they enroll in schools that permit retention, this paper jointly models 1) the decision of entering a school allowing for kindergarten retention, 2) the decision of undergoing a retention treatment in kindergarten, and 3) children's academic performance in higher grades. The retention treatment is modeled as a binary choice with sample selection. The outcome equations are linear regressions including the kindergarten retention dummy as an endogenous regressor with a correlated random coefficient. A control function estimator is developed for estimating the resulting double-hurdle treatment model, which allows for unobserved heterogeneity in the retention effect. As a comparison, a nonparametric bias-corrected nearest neighbor matching estimator is also implemented. Holding children back in kindergarten is found to have positive but diminishing effects on their academic performance up to the third grade. Essay 3 proves the semiparametric identification of a binary choice model having an endogenous regressor without relying on outside instruments. A simple estimator and a test for endogeneity are provided based on this identification. These results are applied to analyze working age male's migration within the US, where labor income is potentially endogenous. Identification relies on the fact that the migration probability among workers is close to linear in age while labor income is nonlinear in age(when both are nonparametrically estimated). Using data from the PSID, this study finds that labor income is endogenous and that ignoring this endogeneity leads to downward bias in the estimated effect of labor income on the migration probability

The spectral line-shape of the mid-IR absorption spectrum provides valuable information about the "hole" polaron coherence length in doped and undoped conjugated polymer films. In poly(3-hexylthiophene) (P3HT) films the spectrum generally consists of a narrow, low-energy peak A (700-1000 $cm^{-1}$) followed by a much broader, higher-energy peak B (2500-5000 $cm^{-1}$). Using a theory based on the Holstein Hamiltonian for mobile holes in P3HT, the IR line-shape is successfully reproduced for several recently measured spectra recorded in doped and undoped films, confirming the association of an enhanced peak ratio (A/B) with extended polaron coherence. Emphasis is placed on the origin of components polarized along the intra- and inter-chain directions and their dependence on the spatial distribution of disorder as well as the position of the dopant relative to the $\pi$-stack. The model is further adapted to treat donor-acceptor copolymers where the local HOMO energy varies periodically from donor unit to acceptor unit. The calculated line shape for a diketopyrrolopyrrole-based copolymer agrees well with the recently measured spectrum.

Texto completoThe compelling astrophysical evidence for dark matter on one hand and the experimental evidence for neutrino masses on the other, demands modifications beyond the Standard Model. Therefore, building new models by extending the symmetries and particle content of the Standard Model is being pursued to remedy these problems. In this thesis, various models along with their predictions are presented. First, a gauge SU(2)N extension of the Standard Model, under which all of the Standard Model particles are singlet is introduced. The inverse seesaw mechanism is implemented for neutrino mass, with the new gauge boson as a dark matter candidate. The second paper is a gauge B-L extension of the Standard Model which breaks down to Z3, and it includes a long-lived dark matter candidate. The next model assumes that leptons do not couple directly to Higgs, and one loop mass generation is considered with important consequences, including Higgs decay, muon anomalous magnetic moment, etc. We then look at a U(1) gauge extension of the supersymmetric Standard Model, which has no μ term, and the Higgs boson's mass supersymmetric constraint is relaxed. The next model is a gauge B-L extension of the Standard Model with radiative seesaw neutrino mass and multipartite dark matter. We then consider another gauge U(1) extension under which quarks and leptons of each family may transform differently, while flavor-changing interactions are suitably suppressed. The next paper has an unbroken gauge SU(2) symmetry, which becomes confining at keV scale. We discuss the cosmological constraints and the implications for future e +e– colliders. Finally, an alternative left-right model is proposed with an automatic residual Z 2 × Z3 symmetry, such that dark matter has two components, i.e., one Dirac fermion and one complex scalar.

The renormalizable Abelian quantum field theory model of Kroll, Lee and Zumino is used to calculate next-to-leading order corrections to the pion electromagnetic form factor in vector meson dominance. At zero temperature the predictions for both the form factor and electromagnetic radius are found to improve greatly over the tree level result, and are in good agreement with the experimental data. A calculation of the vertex and self energy functions in the Matsubara formalism at finite temperature do not agree with the results of the Gale & Kapusta calculations. The resulting prediction for the radius is found to increase with temperature, consistent vith ideas about haclronic deconfinernent.
