A 2.5D coupled FEM-BEM-MFS methodology for longitudinally invariant soil-structure interaction problems
(Elsevier, 2021-04)
Article
Accés obertThis paper is concerned with a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics. The method uses the finite-element method to model the structure, the boundary-element ... -
A comparative study of elastic motions in trajectory tracking of flexible RPR planar manipulators moving with high speed
(2017-07)
Article
Accés restringit per política de l'editorialThe study of inertial forces effects at high speeds in flexible parallel manipulators, which generate undesired deviations, is a challenging task due to the coupled and complicated equations of motion. A dynamic model of ... -

A new averaging-extrapolation method for quasi-periodic frequency refinement
(2022-10)
Article
Accés restringit per política de l'editorialIn a recent work, we presented an averaging-extrapolation approach for the numerical computa- tion of frequencies and amplitudes of a discrete-time quasi-periodic signal. This approach assumes analyticity of the signal and ... -
A structured study on the dynamic bifurcation behavior of a continuous ethanol fermentor
(2021-05)
Article
Accés obertThe oscillatory behavior of a continuous fermentation reactor, in the high feed sugar concentration region (200 g/L), is analyzed using the dynamic bifurcation theory. The mathematical model was solved using the arc-length ... -
About the oscillatory possibilities of the dynamical systems
(2009-11)
Report de recerca
Accés obertThis paper may be ultimately described as an attempt to make feasible the evolutionary emergence of novelty in a supposedly deterministic world whose behavior is associated with that of the mathematical dynamical systems. ... -
Acció del vent sobre edificis complexes: dels assajos en túnels de vent a la creació de càrregues a aplicar a un model d'elements finits
(Universitat Politècnica de Catalunya, 2012-11-26)
Tesina
Accés restringit per decisió de l'autorL’estudi de l’acció del vent sobre edificis complexes (estadis, torres de gran altura...) requereix sovint una precisió superior a l'obtinguda mitjançant l’aplicació directa de les normatives (Eurocodi 1-4) i avui dia ... -

Ageing of an oscillator due to frequency switching
(2021-11-01)
Article
Accés obertIf an oscillator is driven by a force that switches between two frequencies, the dynamics it exhibits depends on the precise manner of switching. Here we take a one-dimensional oscillator and consider scenarios in which ... -
An efficient experimental methodology for the assessment of the dynamic behaviour of resilient elements
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-27)
Article
Accés obertThe assessment of the dynamic behaviour of resilient elements can be performed using the indirect method as described in the standard ISO 10846-3. This paper presents a methodology for control the error on the estimation ... -
Analysis of nonlinear and non-smooth dynamics of a self-oscillating series resonant inverter
(2017)
Text en actes de congrés
Accés obertIn this paper, the dynamics of a dc-ac resonant self-oscillating LC series inverter is analyzed from the point of view of piecewise smooth dynamical systems. Our system is defined by two symmetric configurations and its ... -

Anticipating the response of excitable systems driven by random forcing
(2003-05-23)
Article
Accés obertWe study the regime of anticipated synchronization in unidirectionally coupled model neurons subject to a common external aperiodic forcing that makes their behavior unpredictable. We show numerically and by analog hardware ... -
