Optimisation et Planification de Réseaux de Télécommunications

The problem of minimum cost extension of an existing communication network, over a given time period [0,T], is stated and formulated. A two phase solution method is then described, in which: a) an optimal long-range configuration is sought, assuming static routing all over the period [0,T]; b) the optimal dynamic routing problem is solved by relaxing the fixed routing assumption, and taking int...

Distributed Places

Distributed Places bring new support for distributed, message-passing parallelism to Racket. This paper gives an overview of the programming model and how we had to modify our existing, runtime-system to support distributed places. We show that the freedom to design the programming model helped us to make the implementation tractable. The paper presents an evaluation of the design, examples of ...

Changing Places

By allowing any social institution to structure activity in any place, wireless information services break down the traditional mapping between institutions and places. This phenomenon greatly complicates the analysis of context for purposes of designing context-aware computing systems. Context has a physical, architectural aspect, but most aspects of context will also be defined in institution...
