Imaging and manipulation of skyrmion lattice domains in Cu2OSeO3

Helmuth Berger

Nanoscale chiral skyrmions in noncentrosymmetric helimagnets are promising binary state variables in high-density, low-energy nonvolatile memory. Skyrmions are ubiquitous as an ordered, single-domain lattice phase, which makes it difficult to write informa ...

Frequency capping in online advertising

Moran Feldman

We study the following online problem. There are n advertisers. Each advertiser has a total demand and a value for each supply unit. Supply units arrive one by one in an online fashion, and must be allocated to an agent immediately. Each unit is associated ...

A Novel Approach to Reducing Number of Sensing Units for Wearable Gait Analysis Systems

Kamiar Aminian, Brigitte Jolles-Haeberli, Arash Salarian

Gait analysis methods to estimate spatiotemporal measures, based on two, three or four gyroscopes attached on lower limbs have been discussed in the literature. The most common approach to reduce the number of sensing units is to simplify the underlying bi ...

Contribution to the Active Generator Principle : the Gate-commutated Polyphased Matrix Converter

Antoine Béguin

This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...

Coupling Biot and Navier-Stokes equations for modelling fluid-poroelastic media interaction

Alfio Quarteroni, Annalisa Quaini

The interaction between a fluid and a poroelastic structure is a complex problem that couples the Navier-Stokes equations with the Biot system. The finite element approximation of this problem is involved due to the fact that both subproblems are indefinit ...
