• Optical Monitoring of Microplastics Filtrated from Wastewater Sludge and Suspended in Ethanol 

  Asamoah, Benjamin O.; Salmi, Pauliina; Räty, Jukka; Ryymin, Kalle; Talvitie, Julia; Karjalainen, Anna K.; Kukkonen, Jussi V. K.; Roussey, Matthieu; Peiponen, Kai-Erik (MDPI, 2021)

  The abundance of microplastics (MPs) in the atmosphere, on land, and especially in water bodies is well acknowledged. In this study, we establish an optical method based on three different techniques, namely, specular ...

• An Artificial Decision Maker for Comparing Reference Point Based Interactive Evolutionary Multiobjective Optimization Methods : Evolutionary Multi-Criterion Optimization 

  Afsar, Bekir; Miettinen, Kaisa; Ruiz, Ana B. (Springer, 2021)

  Comparing interactive evolutionary multiobjective optimization methods is controversial. The main difficulties come from features inherent to interactive solution processes involving real decision makers. The human can be ...

• Hidden Strange Nonchaotic Attractors 

  Danca, Marius-F.; Kuznetsov, Nikolay (MDPI AG, 2021)

  In this paper, it is found numerically that the previously found hidden chaotic attractors of the Rabinovich–Fabrikant system actually present the characteristics of strange nonchaotic attractors. For a range of the ...

• Functional a posteriori error estimates for boundary element methods 

  Kurz, Stefan; Pauly, Dirk; Praetorius, Dirk; Repin, Sergey; Sebastian, Daniel (Springer, 2021)

  Functional error estimates are well-established tools for a posteriori error estimation and related adaptive mesh-refinement for the finite element method (FEM). The present work proposes a first functional error estimate ...

• All congruences below stability-preserving fair testing or CFFD 

  Valmari, Antti (Springer, 2020)

  In process algebras, a congruence is an equivalence that remains valid when any subsystem is replaced by an equivalent one. Whether or not an equivalence is a congruence depends on the set of operators used in building ...
