Non-linear spectral estimation
(Institute of Electrical and Electronics Engineers (IEEE), 1987)
Text en actes de congrés
Accés obertThis work describes the use of constraints in variational procedures for spectral analysis. It is reported how the designer in a variational approach for spectral estimation has to select a set of constraints. At the same ... -
On the inverse windowed Fourier transform
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-11-30)
Article
Accés obertThe inversion problem concerning the windowed Fourier transform is considered. It is shown that, out of the infinite solutions that the problem admits, the windowed Fourier transform is the "optimal" solution according to ... -
Ultrashort pulse characterisation with SHG collinear-FROG
(2004-03)
Article
Accés obertWe outline criteria for fast and accurate acquisition of collinear FROG (CFROG) trace and how it can be transformed into the more traditional noncollinear FROG trace. The CFROG has an intrinsically simple geometry that ... -
Validation of numerical models of the offshore wind turbine from the alpha ventus wind farm against full-scale measurements within OC5 Phase III
(American Society of Mechanical Engineers (ASME), 2019)
Text en actes de congrés
Accés restringit per política de l'editorialThe main objective of the Offshore Code Comparison Collaboration Continuation, with Correlation (OC5) project is validation of aero-hydro-servo-elastic simulation tools for offshore wind turbines (OWTs) through comparison ...
