Forwarding and optical indices of a graph
PublicationW pracy rozstrzygnięto dwa problemy dotyczące komunikacji wszyscy-do-wszystkich w grafach. Stwierdzono, że dla wersji skierowanej problemu parametry ''pi'' (maksymalne obciążenie krawędzi) i ''w'' (parametr chromatyczny) nie muszą być w ogólności sobie równe. Dla wersji nieskierowanej problemu pokazano, że wyznaczenie wartości zarówno ''pi'', jak i ''w'', jest w ogólności problemem NP-trudnym.

Architektura kościoła podominikańskiego pw. św. św. Piotra i Pawła w Chełmnie w świetle badań z lat 2010–2013
PublicationKościół dominikański w Chełmnie (Kulm) cieszy się zainteresowaniem badaczy od lat 80-tych XIX wieku, a jego architektura była już przedmiotem kilku opracowań. Jednak dopiero prowadzone od 2010 r. badania architektoniczne świątyni pozwoliły ustalić szereg nieznanych dotąd średniowiecznych etapów i faz jej budowy. Dominikanie zostali sprowadzeni do Chełmna ok. 1236 r. W tym okresie miasto leżało najprawdopodobniej w innej lokalizacji...

Modelling tunnelling-induced deformation in stiff soils with a hyperelastic–plastic anisotropic model
PublicationIn this paper, the tunnelling-induced deformation in anisotropic stiff soils is analysed using FE modelling. The influence of material description is investigated rather than an advanced simulation of the tunnelling method. A new hyperelastic– plastic model is proposed to describe the anisotropic mechanical behaviour of stiff highly overconsolidated soil. This model can reproduce the superposition of variable stress-induced anisotropy...
