Publication history of von Staudt's Geometrie der Lage

From a census of forty copies, we can distinguish three different editions of von Staudt's Geometrie der Lage: the first of 1847 and two undated ones from the 1870's.Comment: 4 page

Analytical comparison of Rankine cycle space radiators constructed of central, double, and block-vapor-chamber fin-tube geometries

Perspective, géométrie et esthétique chez Lambert (II)

International audienceAu cours de notre premier article, nous avons tenté de déterminer le lecteur implicite de Lambert dans son traité de perspective (1759 / 1774) ; nous avons précisé les rapports qu'il établit entre la perspective, la géométrie et l'optique et nous avons décrit l'esthétique qu'il développe. Dans ce second article, nous revenons sur deux annexes que Lambert a ajoutées à la seconde édition de son traité de perspective, à savoir (i) ses quinze problèmes de géométrie à la règle que les géomètres français Hachette, Poncelet et Chasles s'approprieront, (ii) son histoire de la perspective. http://images.math.cnrs.fr/Perspective-geometrie-et,852.htm

Wheel Alignment Measuring Systems

Bakalářská práce se zabývá problematikou zařízením pro měření geometrie kol. V úvodu bakalářské práce jsou uvedeny základní parametry geometrie podvozku vozidla. Následně jsou popsána jednotlivá zařízení pro měření geometrie kol. Poslední části jsem se zabýval moderními trendy a vývojem zařízení pro měření geometrie kol.This bachelor thesis deals with issues of wheel alignment measuring systems. The prime chapter of this bachelor thesis specifies the basic parameters of the wheel suspension geometry. In the next chapter of wheel alignment measuring systems are described. In the final chapter I was dealing with development of the measuring devices and modern trends.

Geometrie

The workshop Geometry, organized by John Lott (Berkeley), André Neves (London), Iskander Taimanov (Novosibirsk) and Burkhard Wilking (Münster) was well attended with over 53 participants with broad geographic representation from all continents. Compared to previous meetings there were for example quite a few young Brazilian postdocs at the meeting. The emphasize on min-max problems and related fields was somewhat increased

Geometrie

The topics discussed at the meeting ranged from geometric evolution equations to minimal surfaces, Riemannian foliations and hyperbolic geometry. Because of a flexible schedule, the 53 participants had ample time for discussion
