Observation of local density increase during pellet homogenization on EAST
Nuclear Fusion, 2023 By combining the X-mode polarized lower and upper cut-off reflections obtained from the density profile reflectometer, we have successfully attained a comprehensive density profile spanning from the edge to the core region in pellet injection (PI ...

Magnetic transmission gear finite element simulation with iron pole hysteresis
Open Physics, 2018 Ferromagnetic poles in a magnetic transmission gear require particular attention during their design process. Usually, during the numerical simulation of these devices the effects of hysteresis for loss estimation are neglected and considered only during

New homogenization approaches for stochastic transport through heterogeneous media
, 2019 The diffusion of molecules in complex intracellular environments can be strongly influenced by spatial heterogeneity and stochasticity. A key challenge when modelling such processes using stochastic random walk frameworks is that negative jump ...
