• (2+1)-dimensional discrete exterior discretization of a general wave model in Minkowski spacetime 

  Mönkölä, Sanna; Räbinä, Jukka; Saksa, Tytti; Rossi, Tuomo (Elsevier, 2025)

  We present a differential geometry-based model for linear wave equations in -dimensional spacetime. This model encompasses acoustic, elastic, and electromagnetic waves and is also applicable in quantum mechanical simulations. ...

• Methods for space-time parameter estimation in DS-CDMA arrays 

  Wu, Rui (University of Jyväskylä, 2006)

  Rui Wu tutki väitöstyössään radiokanavan eri ominaisuuksien arviointia. Tietämys radiokanavan ominaisuuksista on monesti välttämätöntä, jotta radiovastaanottimen vastaanottama signaali voidaan purkaa ymmärrettävään muotoon. ...

• Guaranteed error bounds and local indicators for adaptive solvers using stabilised space-time IgA approximations to parabolic problems 

  Langer, Ulrich; Matculevich, Svetlana; Repin, Sergey (Elsevier, 2019)

  The paper is concerned with space–time IgA approximations to parabolic initial–boundary value problems. We deduce guaranteed and fully computable error bounds adapted to special features of such type of approximations and ...

• Functional Type Error Control for Stabilised Space-Time IgA Approximations to Parabolic Problems 

  Langer, Ulrich; Matculevich, Svetlana; Repin, Sergey (Springer International Publishing, 2018)

  The paper is concerned with reliable space-time IgA schemes for parabolic initial-boundary value problems. We deduce a posteriori error estimates and investigate their applicability to space-time IgA approximations. ...

• Blind recovery of sources for multivariate space-time random fields 

  Muehlmann, C.; De Iaco, S.; Nordhausen, K. (Springer Science and Business Media LLC, 2023)

  With advances in modern worlds technology, huge datasets that show dependencies in space as well as in time occur frequently in practice. As an example, several monitoring stations at different geographical locations track ...
