In each season when the DA pulsating white dwarf G29–38 has been observed, its period spectrum appears very different, but it always contains a forest of harmonics and cross-frequencies. The ratio of the amplitude of these non-linear frequencies Ac to the ...
Les propriétaires immobiliers du canton de Vaud font très peu appel aux subventions du Programme Bâtiments qui encourage les rénovations énergétiques. L’étude «Analyse des barrières à l'assainissement énergétique des bâtiments dans le canton de Vaud» manda ...
The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...
A method and a microscopy imaging apparatus for generating an optically sectioned image of a specimen are provided. The method comprises the steps of:illuminating the specimen with a modulating, spatially periodic illumination pattern; imaging said specime ...
An analysis of the evolution of the amplitude spectrum over many seasons of the DA pulsating white dwarf G29-38 has been performed. Neither beating nor resonant mode coupling can account for the observed appearance and disappearance of modes, although some ...
Switzerland has a small but internationally recognised set of competences and actors in fuel cells and hydrogen, from fundamental research to technology and product development. Swiss organisations are prominent in a number of research partnerships, and so ...
An analysis of the phase spectrum of the DA pulsating white dwarf G29–38 over many seasons has been performed. This complements a companion paper which analyses the evolution of the temporal spectrum of G29–38.We show that, with one exception, the rela ...
