... This translates into a motion of the fluxoids across the superconductor energy dissipation loss of superconductivity To carry a significant current we need to lock the fluxoids so to resist the Lorentz force. For this we mess-up the material and create pinning centers that exert a pinning force ...

Thermal stability of the krypton Hall effect thruster*
... The main goal of the KLIMT project was to figure out if the efficiency of a relatively small HET that is supplied with krypton is comparable with the efficiency produced when xenon propellant is used, and if krypton could indeed be considered as a cost-effective alternative for fueling Hall thruster ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
