In this paper, we present a survey of results about the problem of mapping the N items of a data structure on M memory modules so that items can be accessed in parallel by templates i.e. distinct sets of nodes. In particular, we present some results that allow to access several diierent templates at once, i.e. we focus on versatile mapping algorithms (for a comprehensive survey of other related...

Unfortunately, a 2002 OECD report indicated that there seemed to be declining trust of environmental information sources and increasing confusion about which actions could be most beneficial.

Kenzo is a symbolic computation system devoted to Algebraic Topology. It has been developed by F. Sergeraert mainly as a research artifact. The challenge is now to increase the number of users and to improve its usability. Instead of designing simply a friendly front-end, we have undertaken the task of devising a mediated access to the system, constraining its functionality, but providing guida...
