Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji, Diane Virginie Marie Lançon

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

Cross-field plasma blob motion in an open magnetic field line configuration

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Paolo Ricci, Christian Gabriel Theiler, Gennady Plyushchev, Stefan Müller

The radial propagation of blobs generated from plasma instabilities is investigated in an open magnetic field line configuration. Blob cross-field velocities and sizes are obtained from internal probe measurements using pattern recognition. By varying the ...

Towards Fully Automatic Image Segmentation Evaluation

Touradj Ebrahimi, Lutz Goldmann, Péter Vajda

Spatial region (image) segmentation is a fundamental step for many computer vision applications. Although many methods have been proposed, less work has been done in developing suitable evaluation methodologies for comparing different approaches. The main ...
