Arrest of flow and emergence of activated processes at the glass transition of a suspension of particles with hard sphere-like interactions [PDF]

, 2008
By combining aspects of the coherent and self intermediate scattering functions, measured by dynamical light scattering on a suspension of hard sphere-like particles, we show that the arrest of particle number density fluctuations spreads from the ...

A continuum model for current distribution in Rutherford cables [PDF]

, 2001
An analysis of eddy currents induced in flat Rutherford-type cables by external time dependent magnetic fields has been performed. The induced currents generate in turn a secondary magnetic field which has a longitudinal periodicity (periodic pattern ...

Predetermination of Currents and Field in Short-Circuit Voltage Operation for an Axial-Flux Permanent Magnet Machine [PDF]

, 2008
Risk of irreversible magnet demagnetization during short-circuit fault is analyzed in case of an axial-flux dual-rotor machine, using a three-dimensional finite-element method (3D-FEM).

Experimental Methods and Equivalence Research on Inter-Turn Short Circuits in Power Transformers

Energies
Inter-turn short-circuit faults in power transformers generate enormous short-circuit currents within the affected turns, making full-scale experimental investigations impractical.

A note on the electrical equivalent of the moment theory [PDF]

, 2016
In this short note the relation between the moments of a linear system and the phasors of an electric circuit is discussed. We show that the phasors are a special case of moments and we prove that the components of the solution of a Sylvester equation ...
