A fast model to resolve the velocity-space of fast-ion losses detected in ASDEX Upgrade and MAST Upgrade
(Institute of Physics Publishing, 2019)
A forward model to resolve the fast-ion loss velocity-space on a fast-ion loss detector (FILD) probe head (FILDSIM) has been extended, making it possible to perform real-time analysis of the FILD data ("real-time FILDSIM"). ...

A New Algorithm for the Evaluation of the Elastic Forces in the Absolute Nodal Coordinate Formulation
(Eccomas Proceedia, 2004)
The use of the Absolute Nodal Coordinate Formulation (ANCF) to model flexible multibody systems leads to a system of equations in which the mass matrix is constant. Among other advantages of the ANCF, as the simplicity ...
