We introduce event-recording automata. An event-recording automaton is a timed automaton that contains, for every event a, a clock that records the time of the last occurrence of a...
The states of a computing system bear information and change time, while its events bear time and change information. We develop a primitive algebraic model of this duality of tim...
: User interfaces are often based on static presentations, a model ill suited for conveying change. Consequently, events on the screen frequently startle and confuse users. Cartoon...
