Different coefficients for studying dependence
Oona Rainio
Through computer simulations, we research several different measures of dependence, including Pearson's and Spearman's correlation coefficients, the maximal correlation, the distan…
Circular arc polygons, numerical conformal mappings, and moduli of quadrilaterals
Mohamed Nasser, Oona Rainio, Antti Rasila +4
We study numerical conformal mappings of planar Jordan domains with boundaries consisting of finitely many circular arcs and compute the moduli of quadrilaterals for these domains.…
Intrinsic metrics in ring domains
Oona Rainio
Three hyperbolic type metrics including the triangular ratio metric, the -metric and the Möbius metric are studied in an annular ring. The Euclidean midpoint rotation is intro…
Möbius metric in sector domains
Oona Rainio, Matti Vuorinen
The Möbius metric is studied in the cases where its domain is an open sector of the complex plane. We introduce upper and lower bounds for this metric in terms of the hyp…
Intrinsic metrics under conformal and quasiregular mappings
Oona Rainio
The distortion of six different intrinsic metrics and quasi-metrics under conformal and quasiregular mappings is studied in a few simple domains . The alre…
Condenser capacity and hyperbolic perimeter
Mohamed M. S. Nasser, Oona Rainio, Matti Vuorinen
We study the conformal capacity by using novel computational algorithms based on implementations of the fast multipole method, and analytic techniques. Especially, we apply domain…
