1. QoS management in smart grids: a Markovian approach
In Smart Grids, a variety of new applications are available to users of the electrical system (from consumers to the electric system operators and market operators). Some applications such as the SCADA systems, which control generators or substations, have consequences, for example, with a communication delay. The result of a failure to deliver a control mes

2. Controle em horizonte finito com restriçoes de sistemas lineares discretos com saltos markovianos / Constrained control problem within a finite horizon of markovian jump discrete linear systems
The purpose of this work is to propose and solve the constrained control problem within a finite horizon of Markovian Jump Discrete Linear Systems (MJDLS) driven by noise. The constraints of the state and control vectors are not rigid and limits are established respectively to their first and second moments. The controller is based on a linear state feedback

3. Controle de movimentos coordenados de robôs móveis quando os robôs assumem a liderança de maneira aleatória / Control of coordinated movements of mobile robots when the robots take the lead in a random
This dissertation proposes a study on the automatic control of dynamic systems to the problem of coordination of mobile robots. The coordinated motions are performed with the robots following a leader, and any robot of the formation can assume the leadership randomly. The robots exchange informations according to a pre-specified communication directed graph

4. Array algorithms for filtering of linear systems / Algoritmos array para filtragem de sistemas lineares
This dissertation develops information filter and array algorithms for linear minimum mean square error estimator (LMMSE) of discrete-time Markovian jump linear systems (MJLSs) and fast array algorithms for filtering of standard singular systems. Numerical examples to show the advantage of the array algorithms are presented. Some results obtained in this res

5. State feedback fuzzy-model-based control for Markovian jump nonlinear systems
Neste artigo, apresentam-se projetos de controladores fuzzy para uma classe de sistemas não-lineares com saltos Markovianos. Uma modelagem fuzzy é apresentada para representar esta classe de sistemas na vizinhança de pontos de operação escolhidos. A estrutura do sistema fuzzy é composta de dois níveis, um para descrição dos saltos Markovianos e outr

6. Nonlinear H INFINITO control of underactuated robot manipulators / Controle H INFINITO não linear de robôs manipuladores subatuados
This work presents the development, implementation and analysis of nonlinear H control techniques applied to underactuated manipulators, under parametric uncertainties and external disturbances. At the first part, two approaches are considered for underactuated individual manipulators. The first approach consists in representing manipulators as nonlinear

7. Self-similar LAN/WAN traffic issues on high-speed QoS networks.
During the last decade, the enormous commercial explosion of the Internet has brought up the exhaustive use of Public Telephone Switched Network (PTSN) communication lines by computers (end-users) from all over the world. As a direct consequence of this explosion, a brand new research field, inside the context of the so-called Queuing Theory, has emerged. In

8. Uma metodologia para caracterizaÃÃo de trÃfego de vÃdio baseada nos momentos e primeira e segunda ordem
This thesis presents a new methodology for video traffic characterization. A set of states are defined by a classification algorithm based on the first and second order moments of the codified video sequences. Modulation processes and time series generation that possess statistics associated with the states, defined by the classification algorithm considered

9. Estabilidade e controle de sistemas lineares com saltos Markovianos com horizonte definido por uma classe de tempos de parada / Stability and control of Markovian jump linear systems with horizon defined by a class of stopping times
Este trabalho aborda conceitos de estabilidade de segundo momento e um problema de controle ótimo envolvendo sistemas lineares com saltos Markovianos a tempo discreto. No modelo estudado, define-se como ho-rizonte um tempo de parada t que representa a ocorrência de um número fixo N de falhas ou reparos (TN), ou a ocorrência de uma falha crucial ( t~), ap

10. GENERATION AND TRANSMISSION SYSTEM RELIABILITY CONSIDERING STATIC AND DYNAMIC ASPECTS / CONFIABILIDADE DE SISTEMAS DE GERAÇÃO E TRANSMISSÃO CONSIDERANDO ASPECTOS ESTÁTICOS E DINÂMICOS
Traditionally, bulk power reliability evaluations have concentrated on the analysis of system adequacy, the ability of the generating and the transmission systems to supplhy all loadas within performance requirements. This work presents a new methodology that extends the scope of reliability evaluations to include probabilistic assessment of system security,
