• A numerical method for suspensions of articulated bodies in viscous flows 

  Balboa, F.; Delmotte, B. (2022-09-01)

  An articulated body is defined as a finite number of rigid bodies connected by a set of arbitrary constraints that limit the relative motion between pairs of bodies. Such a general definition encompasses a wide variety of ...

• Aeroacoustic Analysis of a Subsonic Jet using the Discontinuous Galerkin Method 

  Lindblad, D.; Sherwin, S.; Cantwell, C.; Lawrence, J.; Proença, A.; Moragues, M. (2022)

  In this work, the open-source spectral/hp element framework Nektar++ (www.nektar.info) is coupled with the Antares library (www.cerfacs.fr/antares/) to predict noise from a subsonic jet. Nektar++ uses the high-order ...

• A General Framework Based on Walsh Decomposition for Combinatorial Optimization Problems 

  Unanue, I.; Merino, M.; Lozano, J.A. (2021-01-01)

  In this paper we pursue the use of the Fourier transform for a general analysis of combinatorial optimization problems. While combinatorial optimization problems are defined by means of different notions like weights in a ...

• A mathematical analysis of EDAs with distance-based exponential models 

  Unanue, I.; Merino, M.; Lozano, J.A. (2022-09-01)

  Estimation of Distribution Algorithms have been successfully used to solve permutation-based Combinatorial Optimization Problems. In this case, the algorithms use probabilistic models specifically designed for codifying ...

• Zindler-type hypersurfaces in R^4 

  Martinez-Maure, Y.; Rochera, D. (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 ...
