1. COUNTERFACTUAL ANALYSIS BY ALGORITHMIC COMPLEXITY: A METRIC BETWEEN POSSIBLE WORLDS
Abstract Counterfactuals have become an important area of interdisciplinary interest, especially in logic, philosophy of language, epistemology, metaphysics, psychology, decision theory, and even artificial intelligence. In this study, we propose a new form of analysis for counterfactuals: analysis by algorithmic complexity. Inspired by Lewis-Stalnaker's Pos

2. Development of radiofrequency ablation device for surgical hepatocellular carcinoma treatment in agreement with Brazilian standards
Abstract Introduction Many studies have been carried out on the main causes of hepatocellular carcinoma (HCC) to identify suitable diagnosis methods and treatments to combat the disease. However, high equipment costs and the lack of hepatic-ablation technologies manufactured in Brazil encourage the design and implementation of a solution based on normative

3. Determination of the carbon market incremental payoff considering a stochastic jump-diffusion process
The objective of this paper is to verify the robustness of the Least Square Monte Carlo and Grant, Vora & Weeks methods when used to determine the incremental payoff of the carbon market for renewable electricity generation projects, considering that the behavior of the price of Certified Emission Reductions, otherwise known as Carbon Credits, may be modeled

4. From weierstrass to ky fan theorems and existence results on Optimization and Equilibrium Problems
In this work, we study coerciveness notions and their implications to existence conditions. We start with the presentation of classical ideas of coerciveness in the framework of Optimization Theory, and, then, using a classical technical result, introduced by Ky Fan in 1961, we extend these ideas first to Optimization Problems and then to Equilibrium Problem

5. Regularity results for semimonotone operators
We introduce the concept of ρ-semimonotone point-to-set operators in Hilbert spaces. This notion is symmetrical with respect to the graph of T, as is the case for monotonicity, but not for other related notions, like e.g. hypomonotonicity, of which our new class is a relaxation. We give a necessary condition for ρ-semimonotonicity of T in terms of Lispchit

6. Zeros of orthogonal polynomials on the real line / Zeros de polinomios ortogonais na reta real
Results concerning the behaviour of zeros of orthogonal polynomials are obtained. It is known that they are real and distinct and play as important role as node of the most frequently used rules for numerical integration, the Gaussian quadrature formulae. Result about the location and monotonicity of the zeros, considered as functions of parameters involved

7. Existence and concentration of solutions for quasilinear Schrodinger equations / Existencia e concentração de soluções para equações de Schrodinger qase-lineares
In this work we study questions related with existence and concentration of positive solutions for some classes of quasilinear elliptic problems. To obtain our results we use a variational method that allows us to study solutions of the "single-peak" and "multiple-peak" type for a more general class of nonlinearities which do not satisfy necessarily the Ambr

8. Estudo da noção de taxa de variação no ensino médio
O conceito de taxa de variação é muito útil no estudo das funções reais de uma variável real e, por ser elementar, pode ser apresentado e discutido no Ensino Médio. A proposta deste trabalho é fazer um estudo detalhado e criterioso do uso da taxa de variação no estudo das funções afins, quadráticas e cúbicas. Com isso, pretende-se desenvolver

9. Algebraic formulation for modeling hop-by-hop multi-constrained routing algorithms. / Formulação algébrica para a modelagem de algoritmos de roteamento multi-restritivo hop-by-hop.
This work presents a new mathematical structure for paths algebra that allows the convergence analysis of hop-by-hop multi-constrained routing algorithms and, under the traffic engineering and quality of service perspectives in the Generalized Multiprotocol Label Switching (GMPLS) architecture, trustily ensures the aggregation of new routing metrics in a con

10. Test of hypothesis in majoritarian election / Testes de hipóteses em eleições majoritárias
The problem of inference about a proportion, widely explored in the statistical literature, plays a key role in the development of several theories of statistical inference and, invariably, is the object of investigation and discussion in comparative studies among different schools of inference. In addition, the estimation of proportions, as well as test of

12. Freedom, macroeconomics and wappiness: an empirical analisys of a panel of countries / Liberdade, macroeconomia e felicidade: uma análise empírica de um painel de países
This dissertation brings evidence on the role of the main macroeconomic variables and freedom on individual happiness. Using microdata from subjective wellbeing surveys from 74 countries, we estimate an Ordered Probit Model. Based on a standard microeconometric specification, we show that macroeconomics influences wellbeing directly. Even after controlling f
