Given an arbitrary Petri net structure, the deadlock prevention procedure presented here determines a set of linear inequalities on the marking of a Petri net. When the Petri net is supervised so that its markings satisfy these inequalities, the supervised net is proved to be deadlock-free for all initial markings that satisfy the supervision constraints. Deadlock-freedom implies that there wil...

Using a large linked employer-employee data set, this paper studies the extent to which employers insure workers against transitory and permanent firm-level shocks. Particular emphasis is given to the question of whether the amount of wage insurance depends on the nature of industrial relations. Adopting the identification strategy proposed by Guiso et al. (2005), it is shown that wage insuranc...

Powerful, flexible and cost-effective analyses of maritime systems can be conducted in an appropriate way with distributed simulations. Co-simulation components require interoperability like specified by the IEC TC/65/290/DC to insure information exchange and synchronization. Therefore this paper describes a way to insure the interoperability of co-simulations of maritime systems. Userand techn...
