Otimização global para os problemas de redução H2 de modelos e redução H2 da ordem do controlador
A branch and bound algorithm is proposed to solve the H2-norm model reduction problem and the H2-norm controller reduction problem, with conditions assuring convergence to the global optimum in finite time. The lower and ...
A proposed solution to the tail problem of dynamical reduction models
(Elsevier Science BvAmsterdamHolanda, 2001)
H2 and/or H∞-norm model reduction of uncertain discrete-time systems
This paper addresses the problem of model reduction for uncertain discrete-time systems with convex bounded (polytope type) uncertainty. A reduced order precisely known model is obtained in such a way that the H2 and/or ...
Model order reduction in computational multiscale fracture mechanics
(Trans Tech Publications, 2016-01)
Nowadays, the model order reduction techniques have become an intensive research field because of the increasing interest in the computational modeling of complex phenomena in multiphysic problems, and its consequent ...
Convex invertible cones of state space systems

Reaction invariant-based reduction of the activated sludge model ASM1 for batch applications
(Elsevier Ltd, 2016-09)
In any system, there are some properties, quantities or relationships that remain unchanged despite the applied transformations (system invariants). For a batch reaction system with n linearly independent reactions and m ...
Computational hardness of enumerating groundstates of the antiferromagnetic Ising model in triangulations
Satisfying spin-assignments of triangulations of a surface are states of minimum energy of the antiferromagnetic Ising model on triangulations which correspond (via geometric duality) to perfect matchings in cubic bridgeless ...
An improved k-ε turbulence model for FENE-P fluids capable to reach high drag reduction regime
An improved k-ε turbulence model for viscoelastic fluids is developed to predict turbulent flows in complex geometries, with polymeric solutions described by the finitely extensible nonlinear elastic-Peterlin constitutive ...
