Damping Perturbation Based Time Integration Asymptotic Method for Structural Dynamics

Lázaro, Mario (World Scientific, 2022-12)

[EN] In this paper a novel time integration numerical method based on artificial perturbation of damping is proposed. Viscous dissipative terms in the structural dynamics equations of motion are perturbed by an artificial ...
Lower bounds of accuracy for enhanced mode-s distributed sensor networks

Galati, Gaspare; Leonardi, M.; Mantilla Gaviria, Iván Antonio; Tosti, M. (Institution of Engineering and Technology (IET), 2012-03)

The aim of this study is to analyse the accuracy of passive location systems by using the Cramér-Rao lower bound (CRLB). The study is focused on sensor networks derived from the well-known Multilateration (MLAT) systems, ...
Preconditioning the solution of the time- dependent neutron diffusion equation by recycling Krylov subspaces

González Pintor, Sebastián; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Taylor & Francis, 2014-01-02)

[EN] Spectral preconditioners are based on the fact that the convergence rate of Krylov subspace methods is improved if the eigenvalues of smallest magnitude of the system matrix are `removed'. In this paper, two ...
