Acceleration-based fault-tolerant control design of offshore fixed wind turbines
(2016)
Article.
Accés obert
Article.
Accés obert
Wind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft ...
On the Caginalp phase-field systems with two temperatures and the Maxwell–Cattaneo law
(2016-10-31)
Article.
Accés obert
Article.
Accés obert
Our aim in this paper is to study generalizations of the nonconserved and conserved Caginalp phase-¿eld systems based on the Maxwell–Cattaneo law with two temperatures for heat conduction. In particular, we obtain ...
A study of the separating property in Reed-Solomon codes by bounding the minimum distance
(2022-02)
Article.
Accés obert
Article.
Accés obert
According to their strength, the tracing properties of a code can be categorized as frameproof, separating, IPP and TA. It is known that, if the minimum distance of the code is larger than a certain threshold then the TA ...
SCADA data-driven wind turbine main bearing fault prognosis based on one-class support vector machines
(2021-09)
Article.
Accés obert
Article.
Accés obert
This work proposes a fault prognosis methodology to predict the main bearing fault several months in advance and let turbine operators plan ahead. Reducing downtime is of paramount importance in wind energy industry to ...
Nonlinear feature extraction through manifold learning in an electronic tongue classification task
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-08-27)
Article.
Accés obert
Article.
Accés obert
A nonlinear feature extraction-based approach using manifold learning algorithms is developed in order to improve the classification accuracy in an electronic tongue sensor array. The developed signal processing methodology ...
Using the multilinear extension to study some probabilistic power indices
(2017-05-01)
Article.
Accés obert
Article.
Accés obert
We consider binary voting systems modeled by a simple game, in which voters vote independently of each other, and the probability distribution over coalitions is known. The Owen’s multilinear extension of the simple game ...
Interstory-interbuilding actuation schemes for seismic protection of adjacent identical buildings
(2019-07)
Article.
Accés obert
Article.
Accés obert
Rows of closely adjacent buildings with similar dynamic characteristics are common building arrangements in residential areas. In this paper, we present a vibration control strategy for the seismic protection of this kind ...
Understanding gravitational particle production in quintessential inflation
(2019-06-01)
Article.
Accés obert
Article.
Accés obert
The diagonalization method, introduced by a group of Russian scientists at the beginning of seventies, is used to compute the energy density of superheavy massive particles produced due to a sudden phase transition from ...
Arnold diffusion for a complete family of perturbations
(Springer, 2017-01-01)
Article.
Accés obert
Article.
Accés obert
In this work we illustrate the Arnold diffusion in a concrete example — the a priori unstable Hamiltonian system of 2 + 1/2 degrees of freedom H(p, q, I, f, s) = p2/2+ cos q - 1 + I2/2 + h(q, f, s; e) — proving that for ...
Flipped learning and threshold concepts in the Turbomachinery section of Fluid Engineering course

Article.
Accés obert
Article.
Accés obert
This paper outlines a practical intervention aiming to collect the effects of introducing flexible learning in engineering higher education. The work dis- cusses the implementation of the flipped classroom method and the ...
