On the Brauer group of diagonal quartic surfaces

We obtain an easy sufficient condition for the Brauer group of a diagonal quartic surface D over Q to be algebraic. We also give an upper bound for the order of the quotient of the Brauer group of D by the image of the Brauer group of Q. The proof is based ...

Corner Effect and Local Volume Inversion in SiNW FETs

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Luca De Michielis, Luca Selmi

In this paper, a quantitative study of the corner effect and of the local volume inversion on gate-all-around MOSFETs based on numerical simulations has been carried out; different angles and doping levels are compared, in order to understand the impact of ...

On the Design of Integral Observers for Unbiased Output Estimation in the Presence of Uncertainty

Dominique Bonvin, Levente Bodizs

Integral observers are useful tools for estimating the plant states in the presence of non-vanishing disturbances resulting from plant-model mismatch and exogenous disturbances. It is well known that these observers can eliminate bias in all states, given ...

Degraded multicasting with network coding over the combination network

Christina Fragouli, Shirin Saeedi Bidokhti

In this paper, we give a characterization of the rate region for the degraded two message set problem, applied to a combination network with erasure channels. We also provide an algorithm that uses topological information in order to deliver the two messag ...

A mean field approach for optimization in discrete time

Nicolas Gabriel Gast

This paper investigates the limit behavior of Markov decision processes made of independent objects evolving in a common environment, when the number of objects (N) goes to infinity. In the finite horizon case, we show that when the number of objects becom ...

Evolution of dispersal in explicitly spatial metacommunities

Andrea Rinaldo

We apply an evolutionary game theoretic approach to the evolution of dispersal in explicitly spatial metacommunities, using a flexible parametric class of dispersal kernels, namely 2Dt kernels, and study the resulting evolutionary dynamics and outcomes. We ...

Improvement of the one-dimensional dissolved-solute convection equation using the QUICKEST-ULTIMATE algorithm

Rakesh Chawla, Davide Bertolotto

The U.S.-NRC best-estimate system code TRACE adopts a finite volumes, first-order upwind discretization scheme to solve the dissolved-solute convection equation. Such a scheme is known to strongly suffer from numerical diffusion, which can be a significant ...

Slow Time Behavior of the Semidiscrete Perona–Malik Scheme in One Dimension

Maria Colombo

We consider the long time behavior of the semidiscrete scheme for the Perona-Malik equation in one dimension. We prove that approximated solutions converge, in a slow time scale, to solutions of a limit problem. This limit problem evolves piecewise constan ...

Natural Activation for Gesture Recognition Systems

Daniel Thalmann, Patrick Salamin, Frédéric Vexo, Mathieu Hopmann

Gesture recognition is becoming a popular way of interaction, but still suffers of important drawbacks to be integrated in everyday life devices. One of these drawbacks is the activation of the recognition system – trigger gesture - which is generally tiri ...

On the use of an Interoperability Framework in Coopetition Context

Alain Wegmann, Arash Golnam

The simultaneous cooperation and competition between companies referred to as coopetition in the strategy literature is becoming a recurring theme in the business settings. Companies cooperate with their competitors to gain access to supplementary and comp ...
