Complexity of linear relaxations in integer programming

Matthias Schymura

For a set X of integer points in a polyhedron, the smallest number of facets of any polyhedron whose set of integer points coincides with X is called the relaxation complexity rc(X). This parameter was introduced by Kaibel & Weltge (2015) and captures the ...

Coordinate parameterisation and spectral method optimisation for Beltrami field solver in stellarator geometry

David Pfefferlé, Antoine Baillod, Ajay Kumar

The numerical solution of the stepped pressure equilibrium (Hudson et al 2012 Phys. Plasmas 19 112502) requires a fast and robust solver to obtain the Beltrami field in three-dimensional geometry such as stellarators. The spectral method implemented in the ...

Subsurface scattering, in which light refracts into a translucent material to interact with its interior, is the dominant mode of light transport in many types of organic materials. Accounting for this phenomenon is thus crucial for visual realism, but exp ...

Simplified calculation model for interconnected timber elements using wood-wood connections

Julien Gamerro

Metal fasteners and adhesive bonding are the main assembly methods in modern timber constructions. However, traditional wood-wood connections can be used effectively as well, thanks to increasing automation of the construction industry (CNC, robotics, etc. ...

Linear flavor-wave theory for fully antisymmetric SU( N ) irreducible representations

Frédéric Mila, Francisco Hyunkyu Kim, Karlo Penc, Pierre Marcel Nataf

The extension of the linear flavor-wave theory to fully antisymmetric irreducible representations (irreps) of SU(N) is presented in order to investigate the color order of SU(N) antiferromagnetic Heisenberg models in several two-dimensional geometries. The ...

We have recently witnessed the appearance of algorithms that can reconstruct a room’s geometry from echoes, as well as algorithms that use echoes to localize many microphones. This project will consist in implementing a framework for microphone localizatio ...

How about fastening a knot? not with ropes... but with timber panels. Timber Fabric Structures (TFS) originate from such an inspiration. An architectural reinterpretation of fabric techniques (mainly braiding) using building scale timber panels to design ...

Self-consistent Simulations of ICRH with the Background Equilibrium in Tokamaks and Stellarators

Jonathan Graves, Wilfred Anthony Cooper, Martin Jucker

The SCENIC code package has been developed to integrate self-consistently an anisotropic pressure magnetohydrodynamic equilibrium state with power absorption from Ion Cyclotron Resonance Heating and with a guiding center particle distribution function for ...
