• Refined isogeometric analysis of quadratic eigenvalue problems 

  Hashemian, A.; Garcia, D.; Pardo, D.; 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 ...

• Fock-space approach to stochastic susceptible-infected-recovered models 

  Barros de Souza, D.; Araújo, H.; Duarte-Fillho, G.; Gaffney, E.; Nóbrega Santos, F.; Raposo, E. (2022-07-25)

  We investigate the stochastic susceptible-infected-recovered (SIR) model of infectious disease dynamics in the Fock-space approach. In contrast to conventional SIR models based on ordinary differential equations for the ...

• Self-diffusion of spherocylindrical particles flowing under non-uniform shear rate 

  Hernández-Delfin, D.; Weinhart, T.; Hidalgo, R. C. (2022-04-07)

  This work is devoted to study numerically the self-diffusion of spherocylindrical particles flowing down an inclined plane, using the discrete element method (DEM). This system is challenging due to particles being ...

• Offsets and front tire tracks to projective hedgehogs 

  Rochera, D. (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 ...

• Minimax Classification under Concept Drift with Multidimensional Adaptation and Performance Guarantees 

  Alvarez, V.; Mazuelas, S.; Lozano, J.A. (2022-07)

  The statistical characteristics of instance-label pairs often change with time in practical scenarios of supervised classification. Conventional learning techniques adapt to such concept drift accounting for a scalar rate ...
