Two-stage column generation

Michel Bierlaire, Matteo Salani, Ilaria Vacca

We introduce a new concept in column generation for handling complex large scale optimization problems, called two-stage column generation, where columns for the compact and extensive formulation are simultaneously generated. The new framework is specifica ...

Separation and Duality in Locally L0-Convex Modules

Damir Filipovic

Motivated by financial applications, we study convex analysis for modules over the ordered ring L0 of random variables. We establish a module analogue of locally convex vector spaces, namely locally L0-convex modules. In this context, we prove hyperplane s ...

Graph signature for self-reconfiguration planning of modules with symmetry

Auke Ijspeert, Milad Shafiee Ashtiani, Masoud Asadpour

In our previous works we had developed a framework for self-reconfiguration planning based on graph signature and graph edit-distance. The graph signature is a fast isomorphism test between different configurations and the graph edit-distance is a similari ...

Differential geometry applied to crystallography

Philippe Kocian

The mathematical facet of modern crystallography is essentially based on analytical geometry, linear algebra as well as group theory. This study endeavours to approach the geometry and symmetry of crystals using the tools furnished by differential geometry ...

On degraded two-message set broadcast

Christina Fragouli, Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

We consider the two message set problem, where a source broadcasts a common message W1 to an arbitrary set of receivers U and a private message W2 to a subset of the receivers P ⊆U . Transmissions occur over linear deterministic channels. For the case wher ...

Chow-Witt groups and Grothendieck-Witt groups of regular schemes

Jean Fasel

Let A be a noetherian commutative Z[1/2]-algebra of Krull dimension d and let P be a projective A-module of rank d. We use derived Grothendieck-Witt groups and Euler classes to detect some obstructions for P to split off a free factor of rank one. If d

The socle of a projective Mackey functor for a p-group

We study the simple subfunctors of indecomposable projective Mackey functors for a p-group P. Unlike the case of group algebras, the Mackey algebra is not in general self-injective. Thus, the socle of an indecomposable projective functor is not in general ...

to an arbitrary set of receivers

\mathcal{U}

and a private message

Utilisation des outils du système modulaire gradué (SMG) pour estimer les impacts des rejets pluviaux urbains: Avantages et limitations

David Andrew Barry, Luca Rossi, Kathrin Schneider

Today water bodies are suffering from numerous anthropogenic impacts. One of the key players is urban drainage. The directive STORM published by the VSA in 2007 proposes a procedure for an immission oriented strategy for remediation of urban drainage. At t ...

A Fast On-Board Relative Positioning Module for Multi-Robot Systems

Alcherio Martinoli, James Pugh, Xavier Raemy, Riccardo Falconi, Cédric Favre

We present an on-board robotic module which can determine relative positions among miniature robots. The module uses high-frequency modulated infrared emissions to enable nearby robots to determine the range, bearing, and message of the sender with a rapid ...
