13. Termodinâmica de sistemas fullerênicos em soluções / Thermodynamic systems fullerenic solutions
In this work, we present a computational study of the solvation process of the C60 fullerene and its hydroxylated derivate, the fullerenol C60(OH)24, in aqueous environment and organic solvents, using classical molecular dynamics simulations. Diverse sets of parameters to the Lennard-Jones interaction potential have been utilized in simulations of fullerenes

14. Crescimento regional : proposta e análise aplicada ao Brasil
This thesis proposes a new approach for Brazilian regional analysis. This study develops a basic dynamic growth model with factors mobility and its extensions in order to endogenize the total factor productivity (TFP) based on recent studies of economic development. The first chapter develops the basic model for regional growth analysis. It is considered an

15. Economic growth saw investments in capital: evidence empiricists for Brazil / Crescimento econÃmico via investimentos em capital: evidencias empÃricas para o Brasil
In this work it is evident that a not linear relation exists enters the tax of rude formation of capital fixture and the tax of economic growth in Brazilian economy e, which had to this non linearity, the test of predictions of model AK and neoclÃssico considered for Jones (1995) starts to be inconclusivo, therefore exists space for the predictions of both

16. Shape transition and dislocation nucleation in strained epitaxial islands
We study numerically the equilibrium shape, shape transition and dislocation nucleation in strained epitaxial islands with a two-dimensional atomistic model, using interatomic potentials of Lennard-Jones type. The phase diagram for the equilibrium island shapes as a function of island size and lattice misfit with the substrate is obtained by an energy minimi

17. The Brazilian agroexport sector and the foreign direct investment in the MERCOSUL/UE integration context / O setor agroexportador brasileiro e os investimentos diretos externos no contexto da integração MERCOSUL/UE
Having the constitution perspective of MERCOSUL/UE agreement with the possibility of the business strength between the blocks, we analized by the creation esteem and the business detour to the Brazilian agroexport sector the possible gains in four alternative sceneries of integration. It was used a model of partial balance, which the results to the four leve

18. Uma proposta de modelo de referência para mensuração da sustentabilidade corporativa / A proposal of a reference model to measure corporate sustainability
A mensuração da sustentabilidade corporativa é um tema complexo e fundamental para a operacionalização do desenvolvimento sustentável na rotina diária das organizações. Por isso, inúmeros sistemas para sua mensuração foram desenvolvidos após o alerta apresentado pela Agenda 21 Global quanto à sua importância. Apesar da existência desses vári

19. Calculos de estabilidade e divisão de fases por meio de redes neurais artificiais / Phase splitting and stability calculations by means of artificial neural networks
Process simulation is a basic component of different Process Engineering activities such as On-line Optimization, Model Predictive Control, Identification, etc. The calculation of Phase Equilibrium appears as a fundamental task in any simulation of a separation process. However, the high computational time due to the iterative nature of this calculation make

20. Resposta de Consumidores para Modelos como Símbolos de Grupos de Referência em Propaganda do Brasil (Símbolos de Grupos de Referência em Propaganda) / Consumer Response to Models as Reference Group Symbols in Brazilian Advertising (Reference Group Symbols in Advertising)
While previous studies have shown that advertisements in the U.S. are generally most effective when they match the race of the model and consumer. This study found that Brazilian consumers did not respond preferentially to the model of their own race. They also did not demonstrate white backlash nor prejudice towards Blacks. In fact, the model subjects lik

21. Productivity of Nations: a Stochastic Frontier Approach to Tfp Decomposition
This Paper Tackles the Problem of Aggregate Tfp Measurement Using Stochastic Frontier Analysis (Sfa). Data From Penn World Table 6.1 are Used to Estimate a World Production Frontier For a Sample of 75 Countries Over a Long Period (1950-2000) Taking Advantage of the Model Offered By Battese and Coelli (1992). We Also Apply the Decomposition of Tfp Suggested B

22. Um modelo para a superfície líquida no estudo da dinâmica do espalhamento de Xe e Ne pelo esqualano
In this work we present a theoretical model to investigate the scattering of Xe and Ne by a liquid squalane surface. The liquid surface is modeled as a grid of harmonic oscillators with frequencies adjusted to experimental vibration as frequencies of the liquid squalane and the atom-surface interaction potential is modeled by a Lennard-Jones function. The th

23. Molecular Dynamics simulation of the sodium octanoate micelle in aqueous solution: comparison of force field parameters and molecular topology effects on the micellar structure
We have performed a series of 10 ns Molecular Dynamics simulations of the sodium octanoate micelle in aqueous solution in the constant NpT ensemble, at p = 1 bar and T = 300 K. Two molecular topologies were studied, one with all internal degrees of freedom and the other constraining bond stretching and angle bending degrees of freedom. Two Lennard-Jones para

24. VOLATILIDADE ESTOCÁSTICA VIA VEROSSIMILHANÇA DE MONTE CARLO: UM ESTUDO COMPARATIVO / STOCHASTIC VOLATILITY VIA MONTE CARLO LIKELIHOOD: A COMPARATIVE STUDY
This dissertation discusses the estimation of the Stochastic Volatility (SV)model using a Durbin &Koopman methodology called Monte Carlo Like-lihood (MCL). The conditional coverage of value at risk (VaR) of SV via MCL model was compared to the GARCH (1,1) model and to the SV model via Quasi Maximum Likelihood (QML) estimation. The models were extended to Gau
