On-site performance of electrochromic glazings coupled to an anidolic daylighting system

Jean-Louis Scartezzini, Jessen Page, Nicolas Morel

This work takes benefit from two advanced building technologies through the integration of an anidolic daylighting system and an electro-chromic glazing in a building facade for achieving an optimal control of the daylight flux entering in an office room. ...

On-line locomotion synthesis for virtual humans

Pascal Glardon

Ever since the development of Computer Graphics in the industrial and academic worlds in the seventies, public knowledge and expertise have grown in a tremendous way, notably because of the increasing fascination for Computer Animation. This specific field ...

Design and Validation of a Tool for Neurite Tracing and Analysis in Fluorescence Microscopy Images

Michaël Unser, Pascal Steiner, Mathews Jacob

Background: For the investigation of the molecular mechanisms involved in neurite outgrowth and differentiation, accurate and reproducible segmentation and quantification of neuronal processes are a prerequisite. To facilitate this task, we developed a sem ...

Precision Isosurface Rendering of 3-D Image Data

Michaël Unser, Philippe Thévenaz

We address the task of rendering by ray tracing the isosurface of a high-quality continuous model of volumetric discrete and regular data. Based on first principles, we identify the quadratic B-spline as the best model for our purpose. The nonnegativity of ...

Bi-directional light transmission properties assessment for venetian blinds : Computer simulations compared to photogoniometer measurements

Marilyne Andersen, Jean-Louis Scartezzini

An accurate evaluation of daylight distribution through advanced fenestration systems (complex glazing, solar shading systems) requires the knowledge of their Bi-directional light Transmission Distribution Function (BTDF). An innovative equipment for the e ...

AOP: Does it Make Sense ? The Case of Concurrency and Failures

Rachid Guerraoui, Jörg Kienzle

Concurrency and failures are fundamental problems in distributed computing. One likes to think that the mechanisms needed to address these problems can be separated from the rest of the distributed application: in modern words, these mechanisms could be as ...

High-Quality Isosurface Rendering with Exact Gradient

Michaël Unser, Philippe Thévenaz

We address the task of rendering by ray tracing the isosurface of a high-quality continuous spline model of volumetric discrete and regular data. By expressing the spline model as a sum of nonnegative B-splines, we are able to confine the potential locatio ...

Abstract Execution: A Technique for Efficiently Tracing Programs

James Richard Larus

Many areas of computer performance analysis require detailed traces of events that occur during a program's execution. Collecting traces is expensive. The additional code required to record events greatly slows a program's execution. In addition, the resul ...
