Exploiting the Kronecker product structure of φ−functions in exponential integrators 

Muñoz-Matute, J.Autoridad BCAM; Pardo, D.Autoridad BCAM; Calo, Victor M. (2022-05-15)
Exponential time integrators are well-established discretization methods for time semilinear systems of ordinary differential equations. These methods use (Formula presented.) functions, which are matrix functions related ...

Efficient 5-axis CNC trochoidal flank milling of 3D cavities using custom-shaped cutting tools 

Bo, P.; Fan, H.; Barton, M.Autoridad BCAM (2022-05)
A novel method for trochoidal flank milling of 3D cavities bounded by free-form surfaces is proposed. Existing 3D trochoidal milling methods use on-market milling tools whose shape is typically cylindrical or conical, and ...

Time-adaptive Adomian decomposition-based numerical scheme for Euler equations 

Garcia, I.Autoridad BCAM; Remaki, L. (2022-04-21)
Time efficiency is one of the more critical concerns in computational fluid dynamics simulations of industrial applications. Extensive research has been conducted to improve the underlying numerical schemes to achieve time ...

Supervised Deep Learning with Finite Element simulations for damage identification in bridges 

Fernandez-Navamuel, A.Autoridad BCAM; Zamora-Sánchez, Diego; Omella, Ángel J.; Pardo, D.Autoridad BCAM; Garcia-Sanchez, David; Magalhães, Filipe (2022-04-15)
This work proposes a supervised Deep Learning approach for damage identification in bridge structures. We employ a hybrid methodology that incorporates Finite Element simulations to enrich the training phase of a Deep ...

On quadrature rules for solving Partial Differential Equations using Neural Networks 

Rivera, J.AAutoridad BCAM; Taylor, J.M.Autoridad BCAM; Omella, Ángel J.; Pardo, D.Autoridad BCAM (2022-04-01)
Neural Networks have been widely used to solve Partial Differential Equations. These methods require to approximate definite integrals using quadrature rules. Here, we illustrate via 1D numerical examples the quadrature ...

Error representation of the time-marching DPG scheme 

Muñoz-Matute, J.Autoridad BCAM; Demkowicz, Leszek; Pardo, D.Autoridad BCAM (2022-03-01)
In this article, we introduce an error representation function to perform adaptivity in time of the recently developed time-marching Discontinuous Petrov–Galerkin (DPG) scheme. We first provide an analytical expression for ...

Curve-guided 5-axis CNC flank milling of free-form surfaces using custom-shaped tools 

Rajain, K.Autoridad BCAM; Sliusarenko, O.Autoridad BCAM; Bizzarri, M.; Barton, M.Autoridad BCAM (2022-03)
A new method for 5-axis flank milling of free-form surfaces is proposed. Existing flank milling path-planning methods typically use on-market milling tools whose shape is cylindrical or conical, and is therefore not ...

Algebraic equations for constant width curves and Zindler curves 

Rochera, D.Autoridad BCAM (2022-03)
An explicit method to compute algebraic equations of curves of constant width and Zindler curves generated by a family of middle hedgehogs is given thanks to a property of Chebyshev polynomials. This extends the methodology ...

Nonhyperbolic normal moveout stretch correction with deep learning automation 

Abedi, M.M.Autoridad BCAM; Pardo, D.Autoridad BCAM (2022-02-15)
Normal-moveout (NMO) correction is a fundamental step in seismic data processing. It consists of mapping seismic data from recorded traveltimes to corresponding zero-offset times. This process produces wavelet stretching ...

Numerical Approaches for Loads and Motions Assessment of Floating WECs Moored by Means of Catenary Mooring Systems 

Touzon, I.; Petuya, V.; Nava, V.Autoridad BCAM; Alonso-Reig, M.; Mendikoa, I. (2022)
Technologies for harvesting offshore renewable energy based on float- ing platforms, such as offshore wind, wave and tidal energies, are currently being developed with the purpose of achieving a competitive cost of energy. ...
