Calendars, Time Granularities, and Automata
The notion of time granularity comes into play in a variety of problems involving time representation and management in database applications, including temporal database design, t...

A Logical Approach to Represent and Reason about Calendars
In this paper, we propose a logical approach to represent and reason about different time granularities. We identify a time granularity as a discrete infinite sequence of time po...

Supporting Temporal Reasoning by Mapping Calendar Expressions to Minimal Periodic Sets
In the recent years several research efforts have focused on the concept of time granularity and its applications. A first stream of research investigated the mathematical model...

Modeling and Verification of a Fault-Tolerant Real-Time Startup Protocol Using Calendar Automata
We discuss the modeling and verification of real-time systems using the SAL model checker. A new modeling framework based on event calendars enables dense timed systems to be descr...

Performance Evaluation of Components Using a Granularity-based Interface Between Real-Time Calculus and Timed Automata
nalysis of a TA modeled component. First, we abstract fine models to work with event streams at coarse granularity. We perform analysis of the component at multiple coarse granular...
