On a doubly nonlinear diffusion model of chemotaxis with prevention of overcrowding

This paper addresses the existence and regularity of weak solutions for a fully parabolic model of chemotaxis, with prevention of overcrowding, that degenerates in a two-sided fashion, including an extra nonlinearity represented by a p-Laplacian diffusion ...

Stability and Delay Bounds in Heterogeneous Networks of Aggregate Schedulers

Jean-Yves Le Boudec, Gianluca Rizzo

Aggregate scheduling is one of the most promising solutions to the issue of scalability in networks, like DiffServ networks and high speed switches, where hard QoS guarantees are required. For networks of FIFO aggregate schedulers, the main existing suffic ...

Automatic Tonal Harmonization For Multi-Spectral Mosaics

Pouya Dehghani Tafti

When producing a mosaic of multiple multi-spectral images one needs to harmonize the colours so that the tone transition is smooth from one image to the other. Given two images Im(a) and Im(b), a transform T is sought to map Im(b) to an image that is harmo ...

Wavelets on Graphs via Spectral Graph Theory

Pierre Vandergheynst, Rémi Gribonval

We propose a novel method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite graph. We define a notion of scaling using the graph analogue of the Fourier domain, namely the space of eigenfunctions forming the sp ...

The workplace of Traffic Management Center Operators – what changes do experts foresee until 2020?

This paper aims to understand the dynamics of the Traffic Management Center operator workplace. Currently we can observe an expansion of tools, tasks and traffic volumes the operator has to handle. Using expert interviews and Mayring’s Qualitative Content ...

Waypoint navigation with a MAV

Adrien Briod

The goal of the project is to implement a waypoint navigation using GPS as the position input, for an outdoor MAV. A waypoint navigation allows an operator to set a number of places (waypoints) where he wants the plane to pass. The waypoint navigation impl ...

Two-stage column generation and applications in container terminal management

Michel Bierlaire, Matteo Salani, Ilaria Vacca

Seaport container terminals are source of many interesting large-scale optimization problems, which arise in the management of operations at several decision levels. In this paper we firstly illustrate a recently proposed framework, called two-stage column ...
