Hardy Spaces and Boundary Conditions from the Ising Model

Functions in Hardy spaces on multiply-connected domains in the plane are given an explicit characterization in terms of a boundary condition inspired by the two-dimensional Ising model. The key underlying property is the positivity of a certain operator co ...

Global dynamics away from the ground state for the energy-critical nonlinear wave equation

Joachim Krieger

We study global behavior of radial solutions for the nonlinear wave equation with the focusing energy critical nonlinearity in three and five space dimensions. Assuming that the solution has energy at most slightly more than the ground states and gets away ...

The degenerate two well problem for piecewise affine maps

Bernard Dacorogna

The two well problem consists in finding maps u which satisfy some boundary conditions and whose gradient Du assumes values in the two wells . Here (similarly ) is the well generated by a 2 x 2 matrix A, i.e., is the set of matrices of the form RA, where R ...

Tokamak SOL fluid simulations with self-consistent boundary conditions at the magnetic presheath edge

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

Fluid codes simulating the dynamics of magnetized plasmas with field lines terminating on the device vessel require boundary conditions that are consistent with the plasma-wall transition region. When the magnetic field strikes the wall at an oblique angle ...

The Two-Well Problem For Piecewise-Affine Maps

Bernard Dacorogna

In the two-well problem we look for a map u which satisfies Dirichlet boundary conditions and whose gradient Du assumes values in SO (2) A boolean OR SO (2) B = S-A boolean OR S-B, for two given invertible matrices A, B (an element of SO (2) A is of the fo ...

Cecotti-Fendley-Intriligator-Vafa index in a box

Alexander Monin

The Cecotti-Fendley-Intriligator-Vafa (CFIV) index in two-dimensional N = (2,2) models is revisited. We address the problem of "elementary" (nontopological) excitations over a kink solution, in the one-kink sector (using the Wess-Zumino or Landau-Ginzburg ...

Algorithms for the partitioned solution of weakly coupled fluid models for cardiovascular flows

Alfio Quarteroni, Simone Deparis, Adelmo Cristiano Innocenza Malossi

The main goal of this work is to devise robust iterative strategies to partition the solution of the Navier-Stokes equations in a three-dimensional (3D) domain, into non overlapping 3D subdomains, which communicate through the exchange of averaged/integrat ...

An adaptive finite-volume method for a model of two-phase pedestrian flow

Ricardo Esteban Ruiz Baier

A flow composed of two populations of pedestrians moving in different directions is modeled by a two-dimensional system of convection-diffusion equations. An efficient simulation of the two-dimensional model is obtained by a finite-volume scheme combined w ...

Study of the twinned dendrite tip shape II: Experimental assessment

Michel Rappaz, Marco Cantoni, Pierre Burdet, Mario Alberto Salgado Ordorica

The favorable growth kinetics of twinned dendrites can be explained by their complex morphology, multiple side branching mechanisms, growth undercooling and tip morphology. Three models were proposed for the twinned dendrite tip shape: (i) a grooved tip sa ...

UWB antenna design and ray tracing method for robot localization

Anja Skrivervik, Nuno Miguel Faria Pires, Marco Letizia, Benjamin Fuchs

This poster presents a new base station antenna design and preliminary results on electric field mapping for localizing a UWB-MICS robot in an arena. A batch of new base station antenna prototypes, was built and measured at EPFL - LEMA. A microstrip-fed co ...
