Combining Ray-Tracing and Fast Multipole Techniques to Model Extremely Large Electromagnetic Problems Ghent University
When deploying a wireless network, planning is often based on ray-tracing. Ray-tracing is an approximation and its accuracy is difficult to assess. Exact solutions of Maxwell's equations are best obtained using boundary integral equations (BIEs) in conjunction with multilevel Fast Multipole Methods (FMM). In this Ph.D. we investigate the possibility to combine BIE-FMM with ray-tracing into a seamless solver.
Asymptotics for Orthogonal Polynomials and High-frequency Scattering Problems KU Leuven
The goal of this thesis is to exploit asymptotic behaviour in high-degree orthogonal polynomials and high-frequency acoustic scattering problems to obtain %[Dave] problems. This leads to
a lower computational cost. The code is made publicly available and validates this goal as well as the accuracy of the results of this thesis.
We are interested in the higher-order asymptotic behavior of orthogonal polynomials of Jacobi-, ...
Development and Optimization of Photochemical Reactors for Productivity and Efficiency KU Leuven
Continuous photochemical reactors with conventional homogeneous illumination suffer from a photon efficiency problem, which is inherent to their design: dark zones arise near the reagent-rich inlet whereas the reagent depleted outlet is over-illuminated. Any attempt to mitigate dark zones by decreasing the initial concentration of reagent at the inlet of the reactor will only increase photon losses further downstream. This study reports the ...
Development and optimization of X-ray based analytical techniques towards the analysis of rare extraterrestrial materials. Ghent University
Micro-XRF spectroscopy, using synchrotron or conventional X-ray source based excitation, is a well-established non-destructive, microanalytical method, providing information on the elemental distributions in the probed sample. When three dimensional spatially resolved information is of interest, often a confocal micro-XRF detection scheme is applied as an alternative to XRF tomography. However, both methods pose significant challenges when ...
Development of 3D elemental, structural and isotopic microanalysis techniques for the study of unique meteoritic materials Ghent University
This project aims at the development and application of high-end methods for elemental/structural/isotopic micro/nano-analysis making use of laboratory and synchrotron based X-ray imaging methodologies in conjunction with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). The methods developed will be deployed for three-dimensional (3D) morphological, chemical and isotopic characterization of rare meteoritic materials. ...
Development of X-ray Micro-Fluorescence Analysis Tools for Samples Returned by the Hayabusa2 and OSIRIS-REx Missions. Ghent University
The proposed research project is focused on developing improved experimental setups (i.e.
wavelength-dispersive X-ray fluorescence setup for low energies, collimator and confocal optic design
for high energies) and adapted quantification algorithms (i.e. confocal quantification algorithm, 3D Xray scatter visualisation) for the non-destructive analysis of trace-elements (i.e. transition and rare
earth elements) in the samples ...
