Damage identification in bridges combining deep learning and computational mechanic
[EN]Civil infrastructures, such as bridges, are critical assets for society and the economy. Many of them have already reached their expected life and withstand loadings that exceed the design specifications. Besides, ... -
Deep Learning for Inverting Borehole Resistivity Measurements.
Rivera González, Jon Ander (2022-11-25)El subsuelo terrestre está formado por diferentes materiales, principalmente por rocas porosas que posiblemente contienen minerales y están rellenas de agua salada y/o hidrocarburos. Por lo general, las formaciones que ... -
Explicit-in-time variational formulations for goal-oriented adaptivity.
Muñoz Matute, Judit (2019-10-01)Goal-Oriented Adaptivity (GOA) is a powerful tool to accurately approximate physically relevantfeatures of the solution of Partial Differential Equations (PDEs). It delivers optimal grids to solvechallenging engineering ... -
Fast one-dimensional finite element approximation of geophysical measurements
Shahriari Shourabi, Mostafa (2018-11-14)When inverting Logging-While-Drilling (LWD) resistivity measurements, it is a common practice to consider a one-dimensional (1D) layered media to reduce the problem dimensionality using a Hankel transform. Using orthogonality ... -
Goal-oriented adaptivity using unconventional error representations
In Goal-Oriented Adaptivity (GOA), the error in the Quantity of Interest (QoI) is represented using the error functions of the direct and adjoint problems. This error representation is subsequently bounded above by ... -
Model reduction techniques for the fast inversion of Borehole resistivity Measurements
Erdozain Olalla, Aralar (2016-12-15)Las medidas de resistividad en perforaciones a traves de tubos se utilizan de manera común para obteneruna mejor caracterización del subsuelo de la tierra. El uso de un tubo que cubre el pozo complicaenormemente las ... -
Refined isogeometric analysis: a solver-based discretization method
García Lozano, Daniel Alfonso (2018-06-22)Isogeometric Analysis (IGA) is a computational approach frequently employed nowadaysto study problems governed by partial differential equations (PDEs). This approach definesthe geometry using conventional CAD functions ... -
Visibility recovery on images acquired in attenuating media. Application to underwater, fog, and mammographic imaging
Galdrán Cabello, Adrián (2015-12-17)When acquired in attenuating media, digital images of ten suffer from a particularly complex degradation that reduces their visual quality, hindering their suitability for further computational applications, or simply ...
