A new perspective on some approximations used in neutron transport modeling
In this contribution, we will use the Maxwell-Cartesian spherical harmonics (introduced in [1, 2]) to derive a system of partial differential equations governing to thewell known P-N approximation, which is based on the expansion in...

An Experimental Method for Predicting the Magnetic Properties of Ferromagnetic Materials Subjected to Harmonic Excitation
was tested and verified. It is based on the approximation of waveforms in the time domain approximation. In order to predict the waveform or a hysteresis loop, experiments were performed using systematically increasing harmonic...
