Optimizing Kalman optimal observer for state affine systems by input selection
(Pergamon-Elsevier Science Ltd, 2018-07)
In this paper, a new algorithm to build an optimal input for state reconstruction in the class of state-affine systems is proposed, in the sense that it enhances the performances of a Kalman-like observer, as well as it ...
Multidimensional Rovella-like attractors
(2011)
We present a multidimensional flow exhibiting a Rovella-like attractor: a transitive invariant set with a non-Lorenz-like singularity accumulated by regular orbits and a multidimensional non-uniformly expanding invariant ...
A critical value function approach, with an application to persistent time-series
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2016-06-06)
Researchers often rely on the t-statistic to make inference on parameters in statistical models. It is common practice to obtain critical values by simulation techniques. This paper proposes a novel numerical method to ...
