An accurate evaluation of daylight distribution through advanced fenestration systems (complex glazing, solar shading systems) requires the knowledge of their Bidirectional light Transmission (Reflection) Distribution Function BT(R)DF. An innovative equipm ...
An accurate knowledge of the directional optical properties of advanced fenestration materials is necessary for them to be adequately integrated in buildings. These properties are expressed by the Bidirectional Transmission (or Reflection) Distribution Fun ...
We consider the problem of reconstructing superimposed temperature and wind flow fields from acoustic measurements. A new technique based solely on acoustic waves propagation is presented. In contrast to the usual straight ray assumption, a bent ray model ...
In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...
The objective of this paper is to assess the capability of existing lighting simulation methods to predict the performance of Complex Fenestration Systems (CFS), whose potential in daylight and sunlight control make them an increasingly popular alternative ...
We propose a robust autofocus method for reconstructing digital Fresnel holograms. The numerical reconstruction involves simulating the propagation of a complex wave front to the appropriate distance. Since the latter value is difficult to determine manual ...
X-ray waveguides offer a novel approach for nanobeam production, which may become useful in coherent beam imaging and phase contrast projection microscopy. Internal field enhancement, coherency properties, and coupling efficiency of these devices have been ...
We report waveguide-enhanced X-ray experiments on thin macromolecular films, such as spin-coated polymer films, self-assembled polyelectrolyte layers, and lipid membranes, prepared on solid surfaces. Upon the deposition of an additional thin inorganic (met ...
In the moderate magneticfield of TCV (1.5T), the recently installed X3 system (3 gyrotrons @118 GHz, 0.45 MW/each, 2s) broadens the operational space with the possibility of heating plasmas at high density, well above the cutoff density of the X2 system (X ...
Evaluation of solar heat gain and daylight distribution through complex window and shading systems requires the determination of the bi-directional transmission distribution function (BTDF). Measurement of BTDF can be time-consuming, and inaccuracies are l ...
