Algorithmic skeletons are functions representing common parallelization patterns and implemented in parallel. They can be used as the building blocks of parallel and distributed applications by integrating them into a sequential language. In this paper, we present a new approach to programming with skeletons. We integrate the skeletons into an imperative host language, which leads to important ...

Parallel computing is an essential technique to deal with large scaled problems. In recent years, while hardware for parallel computing is getting widely available, developing software for parallel computing remains as a hard task for many programmers. The main difficulties are caused by the communication, synchronization, and data distribution required in parallel programs. This thesis studies...

This paper proposes a new recognition algorithm of mandatory traffic sings using the Hausdorff distance. This algorithm has been designed to detect arrows on traffic signs, especially direction signs. The arrows on these mandatory signs appear in a multitude of different forms and positions. Due to this variety this algorithm uses a structural approach to recognize the arrows. First the sign is...

The integration of a task parallel skeleton into a functional programming language is presented. Task parallel skeletons, as other algorithmic skeletons, represent general parallelization patterns. They are introduced into otherwise sequential languages to enable the development of parallel applications. Into functional programming languages, they naturally are integrated as higher-order functi...

Dynamics of human body skeletons convey significant information for human action recognition. Conventional approaches for modeling skeletons usually rely on hand-crafted parts or traversal rules, thus resulting in limited expressive power and difficulties of generalization. In this work, we propose a novel model of dynamic skeletons called SpatialTemporal Graph Convolutional Networks (ST-GCN), ...

An important question about a ne skeletons is the existence of di erential equations that are related to the A ne Distance and the Area Distance (hence to a ne skeletons) in the same way the Eikonal equation is related to the Euclidean Distance (and the medial axis). We show a surprisingly simple nonlinear second order PDE of Monge-Ampère type that relates to the a ne skeletons (and extends the...

Didier Raoult and Michel Drancourt argue that their recovery of DNAsequences specific to Yersinia pestis from skeletons believed to date from the mid-14th-century Black Death should put a stop to further “speculation” regarding the cause of the epidemic “unless our work is proved to be wrong.” There are several reasons to question the ancient DNA results reported for the Black Death pathogen by...

Soft-bodied organisms with hydrostatic skeletons range enormously in body size, both during the growth of individuals and in the comparison of species. Therefore, body size is an important consideration in an examination of the mechanical function of hydrostatic skeletons. The scaling of hydrostatic skeletons cannot be inferred from existing studies of the lever-like skeletons of vertebrates an...
