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 ...

In Silico Brain Imaging Physically-plausible Methods for Visualizing Neocortical Microcircuitry

Marwan Muhammad Ahmed Abdellah

The recent years have witnessed growing interest in the power of scientific visualization for simulation-based neuroscience. The research presented in this thesis develops methods to generate physically-realistic visualizations of neocortical models recons ...

Compact Lensless Phase Imager

Michaël Unser, Ferréol Arnaud Marie Soulez

Lensless quantitative phase imaging is of high interest for obtaining a large field of view (FOV), typically the size of the camera chip, to observe biological cell material with high contrast. It has the potential to be widely spread due to its inherent s ...

Multilayer four-flux matrix model accounting for directional-diffuse light transfers

Roger Hersch, Mathieu Hébert

The four-flux model is a method to solve light radiative-transfer problems in planar, possibly multilayer structures. The light fluxes are modeled as two collimated and two diffuse beams propagating forward and backward perpendicularly to the layer stack. ...

Optical Thickness Measurements of Vacuum Ultraviolet Radiation in the X2 Expansion Tube

Umar Sheikh

Experiments were conducted in the X2 expansion tube to measure vacuum ultraviolet radiation from shock layers representative of reentry conditions at flight equivalent velocities of 10.0 and 12.2 km/s. Cylindrical models of varying lengths were used to mak ...

Microstructured glazing for daylighting, glare protection, seasonal thermal control and clear view

André Gabriel Kostro

The appropriate choice of glazing in a facade depends on many factors. They include amongst other criteria: location, orientation, climatic condition, energetic efficiency, usage of the building, required user comfort, and the architectural concept. On the ...

High-contrast Computational Caustic Design

Mark Pauly, Yuliy Gennadievich Schwartzburg, Andrea Tagliasacchi, Romain Pierre Testuz

We present a new algorithm for computational caustic design. Our algorithm solves for the shape of a transparent object such that the refracted light paints a desired caustic image on a receiver screen. We introduce an optimal transport formulation to esta ...
