Sliding vector fields for non-smooth dynamical systems having intersecting switching manifolds
(Iop Publishing Ltd, 2015-02-01)
We consider a differential equation p over dot = X(p), p is an element of R-3, with discontinuous right-hand side and discontinuities occurring on a set Sigma. We discuss the dynamics of the sliding mode which occurs when, ...
Chi-squared smoothed adaptive particle-filtering based prognosis
(Academic Press-Elsevier, 2017)
This paper presents a novel form of selecting the likelihood function of the standard sequential importance sampling/re-sampling particle filter (SIR-PF) with a combination of sliding window smoothing and chi-square statistic ...
On variance reduction for stochastic smooth convex optimization with multiplicative noise
(Springer Verlag, 2019)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature and Mathematical Optimization Society. We propose dynamic sampled stochastic approximation (SA) methods for stochastic optimization with a heavy-tailed distribution ...
Gapped Gaussian smoothing technique for debonding assessment with automatic thresholding
(John Wiley and Sons Ltd, 2019)
© 2019 John Wiley & Sons, Ltd.Sandwich structures are subjected to imperfect bonding or debonding caused by defects during the manufacturing process, by fatigue, or by impact loads. In this context, their safety and ...
Insights on the continuous representations of piecewise-smooth nonlinear systems: limits of applicability and effectiveness
(2021-01-01)
Dynamical systems subject to intermittent contact are often modeled with piecewise-smooth contact forces. However, the discontinuous nature of the contact can cause inaccuracies in numerical results or failure in numerical ...
The relationship between inflation and growth: a panel smooth transition regression approach for developed and developing countries
(Universidad de Montevideo, Facultad de Ciencias Empresariales y Economía, Departamento de Economía, 2011)
This paper studies the existence for a set of countries of an inflation threshold above which its effect on economic growth is negative, considering the speed of transition from one inflation regime to the other. Using a ...
Generic Bifurcations of Planar Filippov Systems via Geometric Singular Perturbations
(Belgian Mathematical Soc Triomphe, 2011-01-01)
In this paper we deal with non-smooth vector fields on the plane. We prove that the analysis of their local behavior around certain typical singularities can be treated via singular perturbation theory. In fact, after a ...
