Providing Time-Related Constraints for Conventional Database Systems
A model for a historical database is described which is based upon time-stamped tuples as the unit of storage. The model includes both physical and logical time-stamps. The techni...

Enforcing User-Defined Constraints during the Run-Time in OODB
: In this paper a run-time model is proposed. The run-time model enforces integrity constraints for attributes that are derived from composition and inheritance hierarchies. The ru...

Undecidability over Continuous Time
Since 1996, some models of recursive functions over the real numbers have been analyzed by several researchers. It could be expected that they exhibit a computational power much g...

Persistence of Excitation Properties for Time-Varying Autoregressive Systems
It is well known that a crucial property for the effective identification of time-varying systems is that the data carry continual information on the parameters to be estimated. As...
