• Postprocessing of a finite element scheme with linear elements 

  Neittaanmäki, Pekka; Křižek, Michal (Friedr. Vieweg & Sohn, 1987)

  In this contribution we first give a brief survey of postprocessing techniques for accelerating the convergence of finite element schemes for elliptic problems. We also generalize a local superconvergence technique recently ...

• Adaptation to a limiting element involves mitigation of multiple elemental imbalances 

  Jeyasingh, Punidan D.; Sherman, Ryan E.; Prater, Clay; Pulkkinen, Katja; Ketola, Tarmo (The Royal Society, 2023)

  About 20 elements underlie biology and thus constrain biomass production. Recent systems-level observations indicate that altered supply of one element impacts the processing of most elements encompassing an organism (i.e. ...

• Regularization and finite element approximation of the wave equation with Dirichlet boundary data 

  Lasiecka, I.; Sokołowski, J.; Neittaanmäki, Pekka (Polish Academy of Sciences, Institute of Mathematics, 1990)

  A numerical method for solving the wave equation with nonhomogenuous, nonsmooth Dirichlet boundary condition is proposed. Convergence of the method is proved and some erràr estimates are derived [L-S-2]. The method ...

• An ultrasound-assisted digestion method for the determination of toxic element concentrations in ash samples by inductively coupled plasma optical emission spectrometry 

  Ilander, Aki; Väisänen, Ari (Elsevier, 2007)

  method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of toxic element concentrations (arsenic, barium, cobalt, copper, lead, ...

• „P.S. ich Lidl dich“ : Diskursanalyse der intertextuellen und narrativen Elemente eines Werbespots 

  Vartiainen, Maria (2020)

  Nykypäivänä mainokset ovat yhä näkyvämpi osa yhteiskunnassa ja ihmisten arkipäivässä. Mainosten tehtävänä on välittää tietoa, mutta niiden avulla pyritään vaikuttamaan ihmisiin ja heidän käyttäytymiseensä. Mainokset ovatkin ...
