Many critical services are nowadays provided by large and complex software systems. However the increasing complexity introduces several sources of non-determinism, which may lead to hang failures: the system appears to be running, but part of its services are perceived as unresponsive. On-line monitoring is the only way to detect and to promptly react to such failures. However, when dealing wi...

However, garnierite is not a mineral species recognized by the Commission on New Mineral and Mineral Names (CNMMN). Actually, garnierite is a general name for the NiMg hydrosilicates that usually occur as an intimate mixture that commonly includes two or more of the followi...

We describe and model a new aspect in the design of distributed information systems.

Here, we argu...
