Correspondence functors and duality

A correspondence functor is a functor from the category of finite sets and correspondences to the category of k-modules, where k is a commutative ring. By means of a suitably defined duality, new correspondence functors are constructed, having remarkable p ...

Linear and nonlinear excitation of TAE modes by external electromagnetic perturbations using ORB5

Laurent Villard, Emmanuel Lanti, Alberto Bottino, Mohsen Sadr

The excitation of toroidicity-induced Alfven eigenmodes (TAEs) using prescribed external electromagnetic perturbations (hereafter 'antenna') acting on a confined toroidal plasma, as well as its nonlinear couplings to other modes in the system, is studied. ...

System and method for user data input to modify configurations

Semyon Malamud

A computer-implemented method, computer program product and computer system (100) for editing a configuration of a real-world object to optimize a future state of the real-world object. The configuration includes a plurality of potential states for the rea ...

Correspondence functors and lattices

Jacques Thévenaz, Serge Bouc

A correspondence functor is a functor from the category of finite sets and correspondences to the category of k-modules, where k is a commutative ring. A main tool for this study is the construction of a correspondence functor associated to any finite latt ...

Pullback Scheme Implementation in ORB5

Laurent Villard, Stephan Brunner, Emmanuel Lanti, Alberto Bottino, Noé Thomas Elie Ohana

The pullback scheme is implemented in the global gyrokinetic particle-in-cell code ORB5 (Jolliet et al., 2007[1]) to mitigate the cancellation problem in electromagnetic simulations. The equations and the discretisation used by the code are described. Nume ...

Simple and projective correspondence functors

Jacques Thévenaz, Serge Bouc

A correspondence functor is a functor from the category of finite sets and correspondences to the category of k-modules, where k is a commutative ring. We determine exactly which simple correspondence functors are projective. We also determine which simple ...

Delineation of the Critical Parameters of Salt Catalysts in the N-Formylation of Amines with CO2

Paul Joseph Dyson, Martin Hulla, Dmitry Vasilyev

N-formylation of amines with CO2 is base-catalyzed and studies of salt catalysts reveal that the reaction is efficiently catalyzed by "free" floating anions of high basicity, as represented in the cover image. More information can be found in the Full Pape ...

Robotic Fiber Positioning Systems for Massive Spectroscopic Surveys: Mechanical Design Guidelines and Technological Opportunities

Philipp Hörler

The technology of fiber positioning robots has been evolving in the recent years and currently lacks of a comprehensive view. This thesis aims at filling this gap. Fiber positioning robots are analyzed under different aspects: a theoretical framework, desi ...

Combining the SNR Spectrum with a Cochlear Model

Philip Neil Garner

The SNR spectrum was previously introduced as a natural consequence of using cepstral normalisa- tion in speech recognition; it is closely related to the articulation index of Fletcher. Motivated initially by a theoretical difficulty in frequency warping, ...
