This paper presents Timed Quorum System (TQS), a quorum system for large-scale and dynamic systems. TQS provides guarantees that two quorums, accessed at instances of time that are...
Despite the widespread use of technology for social communication across distance, a number of barriers to such contact still exist. One such barrier is the problem of communicati...
Formal techniques have been widely applied in the design of real-time systems and have significantly helped detect design errors by checking real-time properties of the model. Ho...
A Time Action Lock is a state of a Real-time system at which neither time can progress nor an action can occur. Time Action Locks are often seen as signs of errors in the model or ...
In this paper, we study the observability properties of nonlinear discrete time systems. Two types of contributions are given. First, we present observability criteria in terms of...
