We determine a counterexample to strong diamagnetism for the Laplace operator in the unit disc with a uniform magnetic field and Robin boundary condition. The example follows from the accurate asymptotics of the lowest eigenvalue when the Robin parameter tends to − ∞.
A formula is proposed for the longshore sediment transport in the swash based on the study by Larson et al. on swash-zone transport and foreshore evolution. Hydrodynamics needed to predict the local transport rate were derived from ballistics theory, where both the cases with and without friction were investigated. The formula was validated with data from two experiments carried out in the Large-s
This paper describes a novel tool for eliciting user requirements early in the design process of mobile applications. The "Mobile Oracle", as we have called it, is intended to help developers and designers obtain a better understanding of what the user wants at different points in space and time. It is an extension of a lo-fi version of the well-established Wizard of Oz technique, but it adds an "
The Bremmer series is used to reduce a complex scattering problem to a sequence of simpler single scattering problems. In the Bremmer series, the wave equation is first decomposed into a coupled system of one-way wave equations. The system is then decoupled into a sequence of one-way wave equations with a fixed point iteration. In this paper, a left symbol representation of the decomposition opera
The Writer:
Sigrid Combüchen was born in Solingen in the German Ruhr territory 1942. Shortly after the War her family moved to Sweden. She is a Swedish writer and literary critic and has so far published seven novels, a collection of essays and a biography (on the Norwegian novelist and winner of the Nobel Prize in Literature 1920, Knut Hamsun). She received the 2004 Selma Lagerlöf Prize a
This paper presents a readily computable formula for the real stability radius with respect to an arbitrary stability region in the complex plane.
