Adaptive self-recurrent wavelet neural network and sliding mode controller/observer for a slider crank mechanism
(InderScience Publishers, 2020-10-03)
Article
Accés obertIn this paper, a novel control strategy based on an adaptive Self-Recurrent Wavelet Neural Network (SRWNN) and a sliding mode controller/observer for a slider crank mechanism is proposed. The aim is to reduce the tracking ... -
Analysis of turbulent exchange and coherent structures in the stable atmospheric boundary layer based on tower observations
(2013-11)
Article
Accés obertUsing data collected at the Spanish low troposphere research centre CIBA (Centro de Investigación de la Baja Atmósfera) and at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands, we analysed ... -
Built in dampers for stayed cables in bridges via SMA. The SMARTeR-ESF project: a mesoscopic and macroscopic experimental analysis with numerical simulations
(Elsevier, 2013-04)
Article
Accés obertShape Memory Alloys (SMAs) are good candidates for solid-state dampers appropriate for the oscillations of bridge stay cables because of their large recoverable strain, hysteresis and reasonable fatigue-life. This work ... -
Credit risk contributions under the Vasicek one-factor model: a fast wavelet expansion approximation
(2014-06)
Article
Accés obertTo measure the contribution of individual transactions inside the total risk of a credit portfolio is a major issue in financial institutions. VaR Contributions (VaRC) and Expected Shortfall Contributions (ESC) have become ... -
Estudio y análisis del consumo eléctrico de edificios de uso universitario
(Universitat Politècnica de Catalunya, 2019-05-29)
Treball Final de Grau
Accés obertEl presente trabajo se centra en el estudio de señales de consumo eléctrico de un edificio universitario mediante unas funciones llamadas wavelets. Se presentarán varias de ellas, aunque se utilizará en todo momento la ... -
Haar Wavelets-Based Methods for Credit Risk Portfolio Modeling
(Universitat Politècnica de Catalunya, 2011-11-24)
Tesi
Accés obertIn this dissertation we have investigated the credit risk measurement of a credit portfolio by means of the wavelets theory. Banks became subject to regulatory capital requirements under Basel Accords and also to the ... -
How observed kilometric sandy shoreline undulations depend on wave climate
(2018-05-01)
Article
Accés restringit per política de l'editorialIdier, D.; Falqués, A.; Garcin, M., and Rohmer, J., 2018. How observed kilometric sandy shoreline undulations depend on wave climate. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International ... -
Model based compressed sensing reconstruction algorithms for ECG telemonitoring in WBANs
(2014-12-01)
Article
Accés restringit per política de l'editorialWireless Body area networks (WBANs) consist of sensors that continuously monitor and transmit real time vital signals to a nearby coordinator and then to a remote terminal via the Internet. One of the most important signals ... -
Negative-tension instability of scroll waves and Winfree turbulence in the Oregonator model
(2006-10-06)
Article
Accés obertExcitable media support self-organized scroll waves which can be unstable and give rise to three-dimensional wave chaos. Winfree turbulence of scroll waves results from the negative-tension instability of scroll waves; it ... -
Peaks and jumps reconstruction with B-splines scaling functions
(2014-12-15)
Article
Accés restringit per política de l'editorialWe consider a methodology based on B-splines scaling functions to numerically invert Fourier or Laplace transforms of functions in the space L-2(R). The original function is approximated by a finite combination of jth order ... -
Transient analysis and motor fault detection using the wavelet transform
(INTECH, 2011-04)

Wavelet-denoising on hardware devices with Perfect Reconstruction, low latency and adaptive thresholding
(2013-05)
Article
Accés restringit per política de l'editorialThis paper introduces a wavelet denoising architecture with adaptive thresholding for real-time 1D-systems and without the use of external memories for storing input data or wavelet coefficients. The Discrete Wavelet ...
