The Mesolithic wetland-site of Kerkhove-Stuw (Upper-Scheldt valley, western Belgium) Universiteit Gent
Prior to the excavations at Kerkhove-Stuw, carried out in 2015-2016 by GATE bvba and Ghent University, data gathered through manual and mechanical coring demonstrated the presence of Mesolithic occupations on the top of a Late Glacial levee, adjacent to a palaeochannel of the river Scheldt. The presence of thick packets of Holocene peat and alluvial deposits on top of the levee indicated good preservation conditions for both the archaeological ...
Efficiency of marine acoustic techniques for the archaeological prospection of intertidal areas: results from a test study on the Belgian coast (Ostend-Raversijde) Universiteit Gent
Sub-bottom acoustic studies of intertidal areas along the North Sea coast pose major technological challenges due to the shallow water depth, wave action, strong currents and large tidal range. Moreover in Belgium these areas are often marked by the presence of shallow gas which limits the acoustic penetration. As a result these areas are rarely investigated in a structured way, which is very unfortunate since they have always been a zone of ...
Inferring site function and technological organization from combined spatial, technological and microwear-analyses at the Mesolithic wetland site of Kerkhove-Stuw, northwestern Belgium (preliminary results) Universiteit Gent
The extensive Mesolithic site of Kerkhove-Stuw was located on the top of a natural levee,adjacent to a palaeochannel of the river Scheldt. Subsequently (from the boreal onwards),the landscape was covered by approximately 4,5m to 9m of peat and alluvial clay. The infillof the palaeochannel deposits were studied by means of a high-resolution multi-proxy analysis(i.e. pollen, microcharcoal, loss on ignition, magnetic susceptibility, granulometry, ...

Optical detection of photothermally induced temperature changes in glass-forming liquids KU Leuven
This PhD research made use of advanced all optical methods to measure the response of the glassforming materials glycerol and salol to photothermal excitation, with the aim of extracting information on the frequency and temperature dependence of the heat capacity and the thermal expansion coefficient. Since the characteristic relaxation times of glassformers can vary over several orders of magnitude, the main challenge of the work was to develop ...
Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive 222Ra and 228Ra Beams KU Leuven
There is sparse direct experimental evidence that atomic nuclei can exhibit stable "pear" shapes arising from strong octupole correlations. In order to investigate the nature of octupole collectivity in radium isotopes, electric octupole (E3) matrix elements have been determined for transitions in ^{222,228}Ra nuclei using the method of sub-barrier, multistep Coulomb excitation. Beams of the radioactive radium isotopes were provided by the ...
Thermophysical properties of thin fibers via photothermal quantum dot fluorescence spectral shape-based thermometry KU Leuven
To improve predictions of composite behavior under thermal loads, there is a need to measure the axial thermophysical properties of thin fibers. Current methods to accomplish this have prohibitively long lead times due to extensive sample preparation. This work details the use of quantum dots thermomarkers to measure the surface temperature of thin fibers in a non-contact manner and determine the fibers’ thermal diffusivity. Neural networks are ...
Cardiorespiratory coupling in preterm infants KU Leuven
In preterm infants, a better understanding and quantification of cardiorespiratory coupling may help improve caregiving by enabling the tracking of maturational changes and subclinical signatures of disease. Therefore, in a study of 20 preterm infants admitted to a neonatal intensive care unit, we analyzed the cardiac and respiratory regulatory mechanisms as well as the coupling between them. In particular, we selectively analyzed coupling from ...
