We study the trap depth requirement for the realization of an optical clock using atoms
confined in a lattice. We show that site-to-site tunneling leads to a residual sensitivity to the …

Many implantable medical devices, such as pacemakers, have been recalled due to failure
of their embedded software. This motivates rethinking their design and certification …

The interplay of real time and probability is crucial to the correctness of the IEEE 1394
FireWire root contention protocol. We present a formal verification of the protocol using …

Timed Rebeca is an extension of the actor-based modeling language Rebeca that supports
timing features. Rebeca is purely actor-based with no shared variables and asynchronous …

We consider the reachability problem for timed automata. A standard solution to this problem
involves computing a search tree whose nodes are abstractions of zones. For efficiency …

The actor model is a concurrent object-based computational model in which event-driven
and asynchronously communicating actors are units of concurrency. Actors are widely used …

In this work we apply the timing verification tool OpenKronos, which is based on timed
automata, to verify correctness of numerous asynchronous circuits. The desired behavior of …

Automatic strategy synthesis for a given control objective can be used to generate correct-by-
construction controllers of real-time reactive systems. The existing symbolic approach for …

Models have been used for a long time to build complex systems, in virtually every
engineering field. This is because they provide invaluable helpin making important design …

Timed systems can be considered with two types of semantics–dense time semantics and
discrete time semantics. The most typical examples of both of them are real semantics and …
