A Deep Double Ritz Method (D2RM) for solving Partial Differential Equations using Neural Networks 

Uriarte, C.Autoridad BCAM; Pardo, D.Autoridad BCAM; Muga, I.; Muñoz-Matute, J.Autoridad BCAM (2023-02-15)
Residual minimization is a widely used technique for solving Partial Differential Equations in variational form. It minimizes the dual norm of the residual, which naturally yields a saddle-point (min–max) problem over the ...

Deep Learning for Inverting Borehole Resistivity Measurements 

Rivera, J.AAutoridad BCAM (2022-11-25)
There exist multiple traditional methods to solve inverse problems, mainly, gradient-based or statistics-based methods. However, these methods have severe limitations. In particular, they often need to compute the forward ...

Zindler-type hypersurfaces in R^4 

Martinez-Maure, Y.; Rochera, D.Autoridad BCAM (2022-09-08)
In this paper the definition of Zindler-type hypersurfaces is introduced in $\mathbb{R}^4$ as a generalization of planar Zindler curves. After recalling some properties of planar Zindler curves, it is shown that Zindler ...

Offsets and front tire tracks to projective hedgehogs 

Rochera, D.Autoridad BCAM (2022-07-25)
There are some known properties on curves of constant width and Zindler curves and their relationship with offsets and front tire-track curves in convex geometry. In this work, a generalization of all these concepts and ...

Refined isogeometric analysis of quadratic eigenvalue problems 

Hashemian, A.Autoridad BCAM; Garcia, D.; Pardo, D.Autoridad BCAM; Calo, V.M. (2022-07-16)
Certain applications that analyze damping effects require the solution of quadratic eigenvalue problems (QEPs). We use refined isogeometric analysis (rIGA) to solve quadratic eigenproblems. rIGA discretization, while ...

Machining-induced characteristics of microstructure-supported LPBF-IN718 curved thin walls 

Mishra, S.; Escudero, G.; Gonzalez, H.; Calleja, A.; Martinez, S.; Barton, M.Autoridad BCAM; Lopez de Lacalle, N.; Mishra (2022-07)
The microstructure-supported design of engineering components is recently gaining attention due to their high strength-to-weight and high stiffness-to-weight properties. The present study investigates the hybrid manufacturing ...

Combined model-based and machine learning approach for damage identification in bridge type structures 

Fernandez-Navamuel, A.Autoridad BCAM; Zamora-Sánchez, D.; Armijo-Prieto, A.; Varona-Poncela, T.; García-Sánchez, D.; García-Villena, F.; Ruiz-Cuenca, F. (2022-06)
In this work, we propose a combined approach of model-based and machine learning techniques for damage identification in bridge structures. First, a finite element model is calibrated with real data from experimental ...

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 ...

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 ...
