Fashioning simultaneous migrations: Sonia Delaunay and inter-war Romanian connections

Sonia delaunay: a life in the avant-garde

Sonia Delaunay (1885–1979) was a key figure in the Parisian avant-garde, whose vivid and colourful work spanned painting, fashion and design. In 2015, Tate Modern in London presented the first UK retrospective to assess the breadth of her vibrant artistic career, from her early figurative painting in the 1900s to the energetic abstract work of the 1960s. The exhibition offered a radical reasses...

Connections between Theta-Graphs, Delaunay Triangulations, and Orthogonal Surfaces

Θk-graphs are geometric graphs that appear in the context of graph navigation. The shortest-path metric of these graphs is known to approximate the Euclidean complete graph up to a factor depending on the cone number k and the dimension of the space. TD-Delaunay graphs, a.k.a. triangular-distance Delaunay triangulations introduced by Chew, have been shown to be plane 2-spanners of the 2D Euclid...

Simultaneous Mesh Generation and Partitioning for Delaunay Meshes

In this paper, we present a new approach for the parallel generation and partitioning of unstructured 3D meshes. The new approach couples the mesh generation and partitioning problems into a single optimization problem. Traditionally, these two problems are solved separately, rst generating the mesh (usually sequentially) and then partitioning the mesh either sequentially or in parallel. In the...

An Evaluation of Inter-Switch Connections

In very large clusters it is not possible to get Ethernet-switches that are large enough to support the whole cluster, thus a configuration with multiple switches are needed. This work seeks to evaluate the interconnection strategies for a new 300+ CPU cluster at the University of Southern Denmark. The focal point is a very inexpensive switch from D-Link which unfortunately offers only 24 Gb po...
