One of the main challenges of today’s analytical geography is the back-linking of observed phenomena to individual actions, as not determined by individuals’ structural situation in a one-goal society but by their very choice of spatial goals, i.e. by what ...
We show that, in contrast to the general belief in the distributed computing community, linearizability, the celebrated consistency property, is not always a safety property. More specifically, we give an object for which it is possible to have an infinite ...
The actor computation model is especially suited for concurrent and distributed computations. Actors are basically concurrent processes which communicate through asynchronous message passing. When combined with pattern matching for messages, actor-based pr ...
In practice, concurrent programming systems based on message passing are often instantiations of the actor model. A popular implementation of this form of concurrency is the Erlang programming language. Erlang supports massively concurrent systems such as ...
The actor model has been a model of choice for building reliable distributed systems. On one hand, it ensures that message-processing is serialized within each actor, preserving the familiar sequential programming model. On the other hand, programs written ...
Events on the Web are increasingly being produced in the form of data streams, and are present in many different scenarios and applications such as health monitoring, environmental sensing or social networks. The heterogeneity of event streams has raised t ...
