Investigation et modélisation des tensions circonférentielles en simulation méridienne
… need to be modelled; it is the closure problem. Harmonic closure, which consists in solving a linearized perturbation system in the frequency domain, revealed to be an efficient method to approximate deterministic stresses (He and Ning, 1998, Stridh, 2005, Vilmin, 2006). A fourth averaging can be …

Constructing Landscapes: Towards a Hybrid Tonality
… The appendix to the thesis contains my Harmonic Method on Scales of Increasing Intervals, a set of synthetic scales that can be used to create a set of thirteen four-note chords, as well as several earlier works which give context to the present ones.

Mathematical Analysis of Upscaling Well Log Data from Sonic to Seismic Resolution
… seismic observations. Various upscaling methods have been published and discussed, such as the Simple Averaging method, the Backus Averaging method, the Pair Correlation Function “PCF” method, the General Singular Approximation “GSA” method, and the Markov Chain Monte Carlo “MCMC” method. …

Hydrodynamic and economic modelling of tidal current energy conversion systems.
… velocity profiles; statistical techniques; and harmonic analysis can produce valuable data for site development, device design and grid management. This work developed the application of a directional and time-dependent power coefficient and demonstrates its importance in resource evaluation …

Electric and thermoelectric properties of antiferromagnetic metals
… of AFM order. In addition to the readout methods, we identified materials that provide large readout signals linked to their magnetic order. First, I used anisotropic magnetoresistance (AMR) to probe the Néel vector orientation in the collinear AF Fe$_2$As. AMR depends on the relative …

Modélisation des tensions circonférentielles en simulation méridienne d'écoulements en turbomachines
Le recours systématique à des simulations fluides tridimensionnelles Navier-Stokes étant trop exigeant en phase de conception de turbomachines, la simulation méridienne, bidimensionnelle, plus simple et plus rapide, est utilisée de manière intensive à l'échelle industrielle. Cependant, sa …
