Non‐linear model of the switched reluctance motor with included core losses’ effects
IET Electric Power Applications, 2021 To accurately predict motor performance, considering the effects of core losses is of great importance, especially at speeds much higher than the base where the core losses represent a considerable portion of the total drive losses.

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
Photonics, 2022 We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

A best-fit model of power losses in cold rolled-motor lamination steel operating in a wide range of frequency and magnetization [PDF]
, 2007 A procedure is described for identifying a mathematical model of core losses in ferromagnetic steel based on a minimal amount of experimental data. The new model has a hysteresis loss multiplicative coefficient variable only with frequency, a hysteresis ...

Pulsational Analysis of the Cores of Massive Stars and its Relevance to Pulsar Kicks
, 2004 The mechanism responsible for the natal kicks of neutron stars continues to be a challenging problem. Indeed, many mechanisms have been suggested, and one hydrodynamic mechanism may require large initial asymmetries in the cores of supernova progenitor ...
