Article
Accés obert -
Cepstrum constraints in ME spectral estimation
(Institute of Electrical and Electronics Engineers (IEEE), 1983)
Text en actes de congrés
Accés obertCurrent trends in spectral estimation techniques follow basicaly two guidelines; by introducing modifications in the objctive function to be minimized or, keeping the objetive, by modifying the set of constraints in the ... -
Characteristic spanwise length scales of streamwise vortical structures in the wake of a circular cylinder at Re = 1500 measured via global and local approaches
(Elsevier, 2023-01-30)
Article
Accés restringit per política de l'editorialWake characteristics of the flow past a circular cylinder are analysed in detail at Reynolds number Re = 1500 via direct numerical simulation. A periodic spanwise domain of length 1.5pD has been found to yield correct ... -
Far-field errors due to random noise in cylindrical near-field measurements
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1992-01-31)
Article
Accés obertA full characterization of the far-field noise obtained from cylindrical near-field to far-field transformation, for a white Gaussian, space stationary, near-field noise is derived. A possible source for such noise is the ... -
Temporal and spectral characterization of near-IR femtosecond optical parametric oscillator pulses
(Universitat Politècnica de Catalunya, 2009-09-09)
Projecte Final de Màster Oficial
Accés obertRecently, there has been growing interest in ultrashort pulse measurement techniques. The aim of this work is to utilize interferometric autocorrelator in order to characterize near- IR femtosecond optical parametric ... -
Towards an accurate bioimpedance identification
(IOPScience, 2013)
Text en actes de congrés
Accés obertThis paper describes the local polynomial method (LPM) for estimating the time- invariant bioimpedance frequency response function (FRF) considering both the output-error (OE) and the errors-in-variables (EIV) identi ... -
Univariate and multivariate control charts for monitoring dynamic-behavior processes: a case study
(School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2009-12)
Article
Accés obertThe majority of classic SPC methodologies assume a steady-state (i.e., static) process behavior (i.e., the process mean and variance are constant) without the influence of the dynamic behavior (i.e., an intended or unintended ... -
Use of the most significant autocorrelation lags in iterative me spectral estimation
(1984-04)
