In this paper, we review some recent results about the use of dynamic observers for fault diagnosis of discrete event systems. Dynamic observers can switch sensors on or off, thus ...
Identifying codes have been introduced in 1998 to model fault-detection in multiprocessor systems. In this paper, we introduce two variations of identifying codes: weak codes and ...
Abstract. We study rational streams (over a field) from a coalgebraic perspective. Exploiting the finality of the set of streams, we present an elementary and uniform proof of the ...
In many physical statistical, biological and other investigations it is desirable to approximate a system of points by objects of lower dimension and/or complexity. For this purpo...
In connection with machine arithmetic, we are interested in systems of constraints of the form x + k y + k . Over integers, the satisfiability problem for such systems is polynomi...
