Below you find the complete list of Tier-1-projects since the start of the regular project application programme.

Wave heating and turbulence in the solar atmosphere

Date: 01.12.2017
  • Promotor(s): Norbert Magyar
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
The Sun is one of our most important plasma “laboratories”, where theories of plasma dynamics can be tested through observations. Despite its proximity in astronomical scales, allowing for detailed observations, the solar atmosphere is still enigmatic, harbouring one of the last unsolved problems of classical physics, the coronal heating problem. Via high-resolution magnetohydrodynamic (MHD) simulations, we aim to determine and quantify the dissipation and heating by MHD waves through turbulence or resonant absorption, in different plasma geometries found in the solar atmosphere.

Study of magnetic cusp properties with Particle In Cell simulations

Date: 01.12.2017
  • Promotor(s): Diego Gonzalez Herrero
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
A magnetic cusp is a plasma trap in the shape of a cone which is present in the magnetic fields above and below the poles of the Earth. It is also used for plasma confinement in fusion reactors. In Fusion, magnetic cusps are used because, contrary to others confinement schemes (like tokamac or stellerator), inside the magnetic cusp the plasma always face convex magnetic lines, making It more stable. Using the Particle In Cell code ECsim we will study the beahviour of the magnetic cusp with different plasma parameters and system configurations. The results of this work will give us an insight on the physics of the magnetospheric cusp and will help to improve our understanding of plasma confinement.

Formation and eruption of solar prominences

Date: 01.12.2017
  • Promotor(s): Chun Xia
  • Institution(s): KU Leuven
  • Domain(s): Astronomy and astrophysics
With 3D magnetohydrodynamic simulations, we hope to numerically reproduce the formation and the eruption of solar prominences, considering both the magnetic flux rope structures and the thermodynamic plasma. The detailed magnetic reconnection processes for the flux rope formation in chromosphere and solar flares, triggered by the erupting prominences, in corona will be studied with 3D modeling.

A Sample to Population Cross-Validation Approach to Assess the Robustness and Sensitivity of Pareto-optimal (PO) Selection Designs

Date: 01.12.2017
  • Promotor(s): Wilfried De Corte
  • Institution(s): UGent
  • Domain(s): Psychology
The validity/diversity dilemma constitutes the biggest threat to the practice of personnel selection because applicant pools are increasingly heterogeneous and the most valid pre-employment tests often show substantial mean group difference. To address the issue, methods have been proposed for designing selection systems that are Pareto-optimal (PO) and, hence, are expected to offer the best possible trade-off between the goals of selection quality and diversity. However, it is currently uncertain whether these systems live up to their promise in actual selection applications. Using simulation methods, the present project aims to resolve this uncertainty and to identify the key features that determine the practical performance of PO systems.
