1. Tratamento numérico para equações diferenciais estocásticas através do método da linearização local
In this work, we study the Local Linearization method for the numerical solutionofStochasticDi?erentialEquations(SDEs). Initially,wepresentdefinitions and preliminaries results that provide the theoretical support for the development of this work, such as: Wiener process, existence and uniqueness theorem of solution for SDEs and the stochastic Ito-Taylor exp

2. Further developments in unsteady compressible vortex lattice method in two dimensional motion.
Unsteady phenomena like flutter, buffeting, rapid maneuvers in flight and gust entry are usually modeled and studied by a theoretical treatment involving potential flow methods. The resulting equation from this approach is the governing differential equation for general non-steady, non-viscous, potential flow known as convected wave equation. The disturbance

3. Fuzzy pole placement based on piecewise Lyapunov functions / Controle fuzzy via alocação de pólos com funções de Lyapunov por partes
This work presents a controller design method for fuzzy dynamic systems based on piecewise Lyapunov functions with constraints on the closed-loop pole location. The main idea is to use switched controllers to locate the poles of the system to obtain a satisfactory transient response. The pole placement strategy allows to specify the performance in terms of t

4. Numerical results for a globalized active-set Newton method for mixed complementarity problems
We discuss a globalization scheme for a class of active-set Newton methods for solving the mixed complementarity problem (MCP), which was proposed by the authors in [3]. The attractive features of the local phase of the method are that it requires solving only one system of linear equations per iteration, yet the local superlinear convergence is guaranteed u

5. COMPUTATIONAL ASPECTS OF MARKET EVALUATION OF THE DYNAMIC SECURITY ON POWER ELECTRICAL SYSTEMS / ASPECTOS COMPUTACIONAIS E DE MERCADO DA AVALIAÇÃO DA SEGURANÇA DINÂMICA DE SISTEMAS ELÉTRICOS DE POTÊNCIA
In this work, different methodologies for the dynamic security assessment of electric energy systems, the calculation of preventive control measures and the quantification of the economic impact of the generation rescheduling, are used. For the dynamic security assessment the following modules have been adopted: initial data processing and generation of the

6. A dendritic gain control mechanism in axonless neurons of the locust, Schistocerca americana.
1. To understand the possible function of active dendritic currents in local neurons, the non-linear electrical properties of locust axonless non-spiking interneurons were considered in parallel with the properties of graded transmitter release from their dendrites. 2. The dendritic membrane of the non-spiking interneurons was least responsive to an applied
