For decades, much effort has been made to establish test systems for the determination of magnetic losses of electric steels. However, presently available systems are still associated with considerable deficiencies. Meanwhile, increased awareness of

Rotational magnetization of grain oriented SiFe sheets involves three mechanisms: anisotropy, hysteresis and eddy currents. Apart from describing the respective physical background, the paper is focused on a separation of mechanisms. It discusses dep

The dependence of the width of major domains in grain-oriented SiFe sheet on the frequency and amplitude of sinusoidal magnetization at power frequencies is calculated by minimizing the sum of domain wall and demagnetizing contributions to the mean f

We propose a standard method of establishing the absolute neutron output from small, D-T, 14 MeV neutron generators. This method uses a copper activation measurement in a configuration that we have calibrated with fission ionization chambers from NIS

For single-sheet testers, the field is derived either from the magnetization current or by means of a tangential field coil. The current method, proposed for IEC standardization, is characterized by simple apparatus and good reproducibility but suffe

A project is reviewed which applies electric field plethysmography to both respiratory and cardiac components in an equal way. Electrode positioning and signal processing are optimized in order to produce a sum-signal which finally is separated into

A so-called Impedance Splitting Method is discussed which allows a separation of the impedance Z/sub M/ of the culture medium and the impedance Z/sub E/ of the electrode system. Z/sub E/ shows high sensitivity and yields good results for the initial
