High brightness neutron source optimized for very high pulsed magnetic field experiments
Conducting neutron scattering experiments in the presence of high pulsed magnetic fields, namely above 40 T, provides valuable information about the magnetic structures of materials. However, these experiments are challenging and time-consuming because the ...
EPFL2024Context-based Quality of Experience in Immersive Multimedia
Anne-Flore Nicole Marie Perrin
Since 1895, when the Lumière brothers came out with the projected cinematograph, motion pictures and more generally multimedia contents have considerably improved and are still experiencing a very dynamic development. Advances involved improving various mo ...
EPFL2019A field study investigation on the influence of light level on subjective thermal perception in different seasons
Marilyne Andersen, Jan Wienold, Luisa Pastore, Giorgia Chinazzo
This paper evaluates the influence of light levels (i.e., illuminance) on subjective thermal perception of people, distinguishing between thermal sensation and thermal evaluation. The goal is to investigate whether reported effects found by other studies i ...
NCEUB 20182018Sky Monitoring System
Jean-Louis Scartezzini, Jérôme Henri Kämpf, Yujie Wu
In a sky monitoring system (S), comprising an image sensor (1), a wide angle lens (16), a microprocessor (3), and a memory unit (11, 18), wherein the sky monitoring system (S) is configured to take pictures of a sky scene, wherein the sky monitoring system ...
2018The Pristine survey II: A sample of bright stars observed with FEROS
Extremely metal-poor (EMP) stars are old objects formed in the first Gyr of the Universe. They are rare and, to select them the most successful strategy has been to build on large and low-resolution spectroscopic surveys. The combination of narrow- and bro ...
Wiley-V C H Verlag Gmbh2017Solar reflected glare affecting visual performance
Visual comfort is important to the wellbeing of people and their productivity. However, too much light in the field of view can cause discomfort and disability glare. Under certain conditions it can even cause accidents. This paper addresses the disability ...
2014Healthy lighting: integrating non-visual responses to light into building simulation
The goal of this thesis is to develop a computer-based lighting simulation framework capable of predicting human non-visual responses to light and to validate novel guidelines that can inform designers about how lighting might affect human non-visual respo ...
2013Assessment of Circadian Weighted Radiance Distribution Using a Camera-Like Light Sensor
Jean-Louis Scartezzini, Jérôme Henri Kämpf, Laurent Deschamps, Mirjam Münch, Apiparn Borisuit
Suboptimal light distribution in a room can cause visual discomfort and glare. Next to rods and cones, perception of light is also governed by a third class of photoreceptors, important for circadian rhythm regulation and non-visual functions such as alert ...
EPFL Solar Energy and Building Physics Laboratory (LESO-PB)2013The effect of figural manipulations on brightness differences in the Benary cross
The Benary cross is a classical demonstration showing that the perceived brightness of an area is not solely determined by its luminance, but also by the context in which it is embedded. Despite the fact that two identical grey triangles are flanked by an ...
Pion2011Transmission Illuminance Proxy HDR Imaging: A New Technique to Quantify Luminous Flux
A technique to measure arbitrarily complex luminous fluxes across large areas is presented. The technique is founded on high-dynamic range (HDR) imaging technology and can be achieved using a standard consumer digital camera and everyday materials such as ...
