In asynchronous collaborative applications, users usually collaborate accessing and modifying shared information independently. We have designed and implemented a replicated objec...
Wireless sensor, actuator networks (WSANs) distinguish themselves from wireless sensor networks by the need to coordinate actuators' actions, real-time constraints on communi...
Cooperative Information Systems (CIS) often consist of applications that access shared resources such as databases. Since centralized systems may have a great impact on the system...
In this paper, we explore the use of hierarchically structured multiprocessor tasks (M-tasks) for programming multi-core cluster systems. These systems often have hierarchically s...
-- We estimate the availability, reliability, and mean transaction time (response time) for repairable database configurations, centralized or distributed, in which each service co...
