Modeling and simulation of traffic flow

Recently, investigations of empirical traffic data revealed a variety of phenomena, e.g., metastable states with a very high flow and synchronized traffic flow with a sudden drop in the velocity. In this paper we present a survey of the progresses made in modeling and understanding the dynamic traffic phenomena.  1999 Elsevier Science B.V. All rights reserved.

Design of axisymmetrical tailored concentrators for LED light source applications

In our contribution we present a solution to an important question in the design of a LED-based illumination engine for projection systems: the collimation of the LED light. We tested the principle in the modification of a common device in non-imaging optics, the compound Parabolic Concentrator. This CPC-like achieves a collection of 72% (ideal reflective coating presumed). This CPC-like was ta...

Theoretical Bases of Photovoltaic Concentrators for Extended Light Sources

The theoretical bases for casting maximum energy on a cell placed in a static concentrator of minimum entry aperture are derived. Several concentrators are analysed according to this theory and the gain achievable with each is obtained. When practical materials are used the maximum gain is about 9 for the direct beam source and about 4.5 for diffuse radiation. One of the concentrators analysed ...
