1. Imposition of Dirichlet Boundary Conditions in Element Free Galerkin Method through an Object-Oriented Implementation
Abstract One of the main drawbacks of Element Free Galerkin (EFG) method is its dependence on moving least square shape functions which don’t satisfy the Kronecker Delta property, so in this method it’s not possible to apply Dirichlet boundary conditions directly. The aim of the present paper is to discuss different aspects of three widely used methods o

2. Integrating Ridge-type regularization in fuzzy nonlinear regression
In this paper, we deal with the ridge-type estimator for fuzzy nonlinear regression models using fuzzy numbers and Gaussian basis functions. Shrinkage regularization methods are used in linear and nonlinear regression models to yield consistent estimators. Here, we propose a weighted ridge penalty on a fuzzy nonlinear regression model, then select the number

3. Controle ótimo por modos deslizantes via função penalidade / Optimal sliding mode control approach penalty function
Este trabalho aborda o problema de controle ótimo por modos deslizantes via função penalidade para sistemas de tempo discreto. Para resolver este problema será desenvolvido uma estrutura matricial alternativa baseada no problema de mínimos quadrados ponderados e funções penalidade. A partir desta nova formulação é possível obter a lei de controle

4. Gerenciamento da oferta e da demanda em micro-sistemas de energia via otimização por enxames de partículas
Intelligent micro-grids, which integrate distributed energy resources with loads, are among the current major tendencies for electric power distribution systems. Distributed resources promote important changes in the operation and management of the distribution system, since they require that the control and the intelligence of the system must be distributed

5. Variable selection for survival models based on penalized likelihood / Seleção de covariáveis para modelos de sobrevivência via verossimilhança penalizada
Variable selection is an important step when setting a parsimonious model. However, the most popular variable selection techniques, such as the best subset variable selection and the stepwise method, do not take into account inherent stochastic errors in the variable selection step. This work presents a study of alternative procedures to more popular methods

6. Recursive robust regulator for discrete-time state-space systems / Regulador robusto recursivo para sistemas lineares de tempo discreto no espaço de estado
This dissertation deals with robust recursive regulators for discrete-time systems subject to parametric uncertainties. A new quadratic functional based on the combination of penalty functions and game theory is proposed to solve this class of problems. An important issue of this approach is that the recursiveness can be performed without the need of adjusti

7. Filtros de Kalman robustos para sistemas dinâmicos singulares em tempo discreto / Robust Kalman filters for discrete-time singular systems
This thesis considers the optimal robust estimates problem for discrete-time singular dymanic systems. New recursive algorithms are developed for the Kalman filtered and predicted estimated recursions with the corresponding Riccati equations. The singular robust Kalman type filter and the corresponding recursive Riccati equation arer obtained in their most g

8. Conversão simbólica de sinais digitais por meio da Teoria de Extremos Relativos
The goal is to develop a new technique for symbolic conversion of digital signals, called Quantization based on Relative Extrema (QBER). This technique can convert unidimensional digital signals into strings. The technique QBER, formalized in this proposal, uses Relative Extrema Theory (TER ) and signals similarity functions, as metric Edit Distance with Rea

9. Cláusula penal e o código civil de 2002
The main purpose of this paper is to evidence the need to overrule the unitary theory of the penalty clause, which is the one adopted by the traditional doctrine and according to which the institute has the nature of a liquidated damages clause, regardless of the intent of the parties upon its creation, being any compulsory effect merely secondary. In order

10. Estudo do fenômeno da auto-intersecção em um anel anisotrópico / Study of the self-intersection anomaly in an anisotropic ring
This work concerns a numerical study of a homogeneous circular plate with a centered hole that is under a state of plane strain. The plate is fixed at its inner surface and is under uniform radial compression at its outer surface. The plate is linear, elastic, and anisotropic. An analytical solution for this problem, which satisfies the governing equations o

11. An extension of the partition of unity finite element method
Here, we propose an extension of the Partition of Unit Finite Element Method (PUFEM) and a numerical procedure for the solution of J2 plasticity problems. The proposed method is based in the Moving Least Square Approximation (MLSA) and is capable of overcoming singularity problems, in the global shape functions, resulting from the consideration of linear or

12. A culpabilidade e a puniÃÃo da pessoa jurÃdica em delitos ambientais: a necessÃria revisÃo da dogmÃtica penal / Corporate culpability and punishment in offences against the environment: the necessary reviewing of criminal law dogmas
Corporate liability for damages to the environment: a theme of paramount relevance having deserved interest among all scholars dealing with Criminal, Economic, Environmental and Constitutional Law. Once having defined the legal model of environmental tutorship, the study of sanctions as instruments of protection follows, and, necessarily, the question of cor
