...Jeno Takacs Purpose The purpose of this paper is to model one of the unsolved problems of magnetism, the reversal of hysteresis loops, in an analytical way. The mathematical models, describing the multiphase steel used in engineering practice, without any exception, are unsuited to provide a way...

... mathematical models for the simulation of OPV devices that combine a continuum representation of charge transport and diffusion of excited states in bulk materials with an ad hoc description of phenomena occurring at the interfaces (Barker et al., 2003 ; Ruhstaller et al., 2003 ; Williams...
