Bio-physically plausible visualization of highly scattering fluorescent neocortical models for in silico experimentation

Henry Markram, Felix Schürmann, Marwan Muhammad Ahmed Abdellah, Julian Charles Shillcock, Stefan Eilemann, Ahmet Bilgili

Background: We present a visualization pipeline capable of accurate rendering of highly scattering fluorescent neocortical neuronal models. The pipeline is mainly developed to serve the computational neurobiology community. It allows the scientists to visu ...

Dye-sensitized solar cells for efficient power generation under ambient lighting

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Paul Liska, Fabrizio Giordano, Ulf Anders Hagfeldt, Joël Teuscher, Xiaoyu Zhang, Yasemin Saygili, Marina Freitag

Solar cells that operate efficiently under indoor lighting are of great practical interest as they can serve as electric power sources for portable electronics and devices for wireless sensor networks or the Internet of Things. Here, we demonstrate a dye-s ...

Visible light-emitting host-guest electrochemical cells using cyanine dyes

Frank Nüesch, Roland Hany, Jakob Heier, Lei Wang, Beat Ruhstaller, Surendra Babu Anantharaman

Light-emitting electrochemical cells (LECs) can be fabricated as a single emissive organic/salt layer sandwiched between two electrodes, offering cost-effective next generation signage and lighting applications. Cyanine dyes are especially attractive to ex ...

Spatial interpolation of experimental raindrop size distribution spectra

Alexis Berne, Timothy Hugh Raupach

We present a new approach for spatial interpolation of experimental raindrop size distribution (DSD) spectra. The DSD is fundamental to the study and understanding of precipitation and its monitoring and modelling. It is measured insitu using disdrometers ...

The influence of the Level of Detail (LOD) on the assessment of the photovoltaic (PV) potential in urban environments

Stéphane Bonjour, Jérémie Stoeckli

In the 3D-modelling universe, the Level of Detail has a crucial role, as it is the case to assess the PV potential in urban environments using this kind of models. According to the CityGML standards, there are five levels of detail, going from the footprin ...

Accurate recovery of a specularity from a few samples of the reflectance function

Martin Vetterli, Ivan Dokmanic, Loïc Arnaud Baboulaz, Gilles Baechler

We present a new technique for estimating the specular peak of the bidirectional reflectance distribution function (BRDF) based on finite rate of innovation (FRI) sampling. The specular component of the BRDF varies rapidly, so it is challenging to acquire ...

Color reproduction, pattern hiding and image alternations with halftone prints on metal

Roger Hersch, Petar Pjanic

We propose new methods for creating color or achromatic images that are printed with classical cyan, magenta, yellow and a white diffusing ink on a metallic substrate. We optimize the surface coverages of the cyan, magenta, yellow and white inks in order t ...

Yule-Nielsen based multi-angle reflectance prediction of metallic halftones

Roger Hersch, Vahid Babaei

Spectral prediction models are widely used for characterizing classical, almost transparent ink halftones printed on a diffuse substrate. Metallic-ink prints however reflect a significant portion of light in the specular direction. Due to their opaque natu ...

Transparent and Specular Object Reconstruction with a Plenoptic Camera

Ying Song

Over the past two decades, most techniques that have been developed are focused on opaque objects with Lambertian reflectance. For the transparent and specular objects, they have more complex light transport effect, which pose challenging problems for the ...
