A proper choice of boundary conditions plays a significant role in the problems studied in continuum fluid dynamics. In many theoretical studies as well as numerical experiments, the standard… (More)

Abstract. Let Ω be an exterior domain in R (n = 2, 3, 4) , with boundary being not necessarily smooth. For any initial velocity u0 ∈ L(Ω) such that ∇ · u0 = 0 (in sense of distribution) and external… (More)

Butlerbot is a robot designed to serve drinks at receptions. Due to the expected close proximity between the robot and the users, a new compliant geometry concept has been used, where the body shape… (More)

From 03.04.05 to 06.04.05, the Dagstuhl Seminar 05142 Disruption Tolerant Networking was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several… (More)

In this paper we consider weak solutions u : Ω → Rd to the equations of stationary motion of a fluid with shear dependent viscosity in a bounded domain Ω ⊂ Rd (d = 2 or d = 3). For the critical case… (More)

We consider the equations of slow stationary motion of a perfectly plastic fluid in a bounded domain Ω ⊂ Rn (n = 2 or n = 3). The proof of the existence of a weak solution to these equations leads to… (More)
