Design of a state observer using decay rate LMI constraints for fault detection in mechanical systems
(2010-01-01)
Nowadays, one of the most important concerns for many companies is to maintain the operation of their systems without sudden equipment break down. Because of this, new techniques for fault detection and location in mechanical ...

Spectrum of the fractional p-Laplacian in RN and decay estimate for positive solutions of a Schrödinger equation
(Pergamon-Elsevier Science Ltd, 2020-04)
In this paper, we prove the existence of unbounded sequence of eigenvalues for the fractional p−Laplacian with weight in RN. We also show a nonexistence result when the weight has positive integral. In addition, we show ...
On the Validity of the Relationship 1/T = 1/T B+1/T S+1/T D in NMR Techniques With Regards to Permeability Estimation of Natural Porous Media
(Frontiers Media, 2021)
One of the most relevant feature of geophysical techniques based on nuclear magnetic resonance is their ability to estimate the permeability of natural porous media, since other geophysical techniques, as the use of the ...
Almost sharp nonlinear scattering in one-dimensional born-infeld equations arising in nonlinear electrodynamics
(American Mathematical Society, 2018)
We study decay of small solutions of the Born-Infeld equation in 1+1 dimensions, a quasilinear scalar field equation modeling nonlinear electromagnetism, as well as branes in String theory and minimal surfaces in Minkowski ...
Microscopic model to nucleon spectra in hypernuclear non-mesonic weak decay
(Elsevier Science, 2013-01-08)
A consistent microscopic model is applied to the calculation of the nucleon emission spectra in the nonmesonic weak decay of Λ-hypernuclei. We adopt a nuclear matter formalism extended to finite nuclei via the local density ...
Fractional derivative estimates in Gevrey spaces, global regularity and decay for solutions to semilinear equations in R-n

Existence, uniqueness and decay rates for evolution equations on trees
(European Mathematical Society, 2014-04)
We study evolution equations governed by an averaging operator on a directed tree, showing existence and uniqueness of solutions. In addition we find conditions of the initial condition that allows us to find the asymptotic ...
Photocurrent decay from the steady-state in thin film hydrogenated amorphous silicon: Numerical simulation analysis of experimental results
(Elsevier Science SA, 2020-10)
Starting from the multiple trapping rate equations that define the non-equilibrium concentrations of electrons and holes in extended states, the experiment of photocurrent decay from the steady-state is examined. A system ...
