Specification, modelling, verification and runtime analysis of real time systems

Checking Correctness At Runtime using Real-Time Java

Correctness of a real-time system depends on its computation as well as its timeliness. In recent years, research has been focusing on verifying the correctness of a real-time system during runtime by monitoring its runtime execution and checking it against its formal specifications. Such verification method is called Runtime Verification. While a few existing runtime verification tools verify ...

Safety Verification of Real Time Systems Serving Periodic Devices

In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...

The Theory and Practice of SALT

Salt is a general purpose specification and assertion language developed for creating concise temporal specifications to be used in industrial verification environments. It incorporates ideas of existing approaches, such as PSL or Specification Patterns, in that it provides operators to express scopes and exceptions, as well as support for a subset of regular expressions. On the one hand side, ...

Formal Method in Service Composition in Heath Care Systems

One of the areas with greatest needs having available information at the right moment and with high accuracy is healthcare. Right information at right time saves lives. Healthcare is a vital domain which needs high processing power for high amounts of data. Due to the critical and the special characteristics of these systems, formal methods are used for specification, description and verificati...
