• 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 ...

• Occurrence and recovery potential of rare earth elements in Finnish peat and biomass combustion fly ash 

  Perämäki, Siiri; Tiihonen, Antti; Väisänen, Ari (Elsevier BV, 2019)

  Rare earth elements (REEs) are highly important in the modern society as a result of their wide use in various fields of industry. Their high supply risk and increase in demand has led to classification as critical materials, ...

• 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 ...

• Mindfulness, acceptance and value-based intervention for burnout : mediational roles of learning the elements of the intervention on outcomes 

  Kuitunen, Milja; Rantala, Maria (2015)

  The effects of mindfulness-based interventions and ACT on mindfulness and well-being have received a lot of interest, and their mechanisms of change have been studied recently, but still some mechanisms are missing the ...

• Appraisals of Salient Visual Elements in Web Page Design 

  Silvennoinen, Johanna; Jokinen, Jussi (Hindawi Publishing Corporation, 2016)

  Visual elements in user interfaces elicit emotions in users and are, therefore, essential to users interacting with different software. Although there is research on the relationship between emotional experience and visual ...
