Border detection in digital images: An approach by fuzzy numbers
(2007-12-01)
The purpose of this paper is to introduce a new approach for edge detection in gray shaded images. The proposed approach is based on the fuzzy number theory. The idea is to deal with the uncertainties concerning the gray ...
Comparative study of LMI-based output feedback spr synthesis for plants with different numbers of inputs and outputs
(2008-09-24)
New Linear Matrix Inequalities (LMI) conditions are proposed for the following problem, called Strictly Positive Real (SPR) synthesis: given a linear time-invariant plant, find a constant output feedback matrix Ko and a ...
The LQ control problem for Markovian jumps linear systems with horizon defined by stopping times
(2004-11-29)
This paper deals with a stochastic optimal control problem involving discrete-time jump Markov linear systems. The jumps or changes between the system operation modes evolve according to an underlying Markov chain. In the ...
A constructive heuristic algorithm to Short Term Transmission Network Expansion Planning
(2004-12-01)
In this paper a method for solving the Short Term Transmission Network Expansion Planning (STTNEP) problem is presented. The STTNEP is a very complex mixed integer nonlinear programming problem that presents a combinatorial ...
