Numerical simulation of the magnetization of high-temperature superconductors: 3D finite element method using a single time-step iteration
Gregory P. Lousberg, Marcel Ausloos, Christophe Geuzaine +3
We make progress towards a 3D finite-element model for the magnetization of a high temperature superconductor (HTS): We suggest a method that takes into account demagnetisation eff…
Measurement of the magnetic field inside the holes of a drilled bulk high-Tc superconductor
Gregory P Lousberg, Jean-Francois Fagnard, Jacques G Noudem +3
We use macroscopic holes drilled in a bulk YBCO superconductor to probe its magnetic properties in the volume of the sample. The sample is subjected to an AC magnetic flux with a d…
Bulk high-Tc superconductors with drilled holes: how to arrange the holes to maximize the trapped magnetic flux ?
Gregory P Lousberg, M Ausloos, Ph Vanderbemden +1
Drilling holes in a bulk high-Tc superconductor enhances the oxygen annealing and the heat exchange with the cooling liquid. However, drilling holes also reduces the amount of magn…
High frequency intrinsic modes in El Niño Southern Oscillation Index
Filippo Petroni, Marcel Ausloos
Recent data of the Southern Oscillation Index have been analyzed. The power spectrum indicates major intrinsic geophysical short periods. We find interesting ``high frequen…
An AC susceptometer for the characterization of large, bulk superconducting samples
P Laurent, J F Fagnard, B Vanderheyden +4
The main purpose of this work was to design, develop and construct a simple, low-cost AC susceptometer to measure large, bulk superconducting samples (up to 32 mm in diameter) in t…
Statistical-mechanics approach to a reinforcement learning model with memory
Adam Lipowski, Krzysztof Gontarek, Marcel Ausloos
We introduce a two-player model of reinforcement learning with memory. Past actions of an iterated game are stored in a memory and used to determine player's next action. To examin…
