摘要:Abstract(#br)Rumors can propagate at great speed through social networks and produce significant damages. In order to control rumor propagation, spreading correct information to counterbalance the effect of the rumor seems more appropriate than simply blocking rumors by censorshi...

摘要:Abstract(#br)This paper deals with the problem of decentralized observability of discrete event systems. We consider a set of sites each capable of observing a subset of the total event set. When a synchronization occurs, each site transmits its own observation to a coordinator t...

摘要:Abstract(#br)The goal of this paper is to overview the historical development of the field of Petri nets (PNs) from a Systems Theory and Automatic Control perspective. It is intentionally not meant to be comprehensive: we limit ourselves to outline, through selected representativ...

摘要:Abstract(#br)A system is said to be opaque if an intruder that observes its evolution through a mask cannot infer that the system’s evolution belongs to a given secret behavior. Opacity verification is the problem of determining whether the system is opaque with respect to a...

摘要:Abstract(#br)The state estimation problem is a fundamental issue in discrete event systems. Partial observations arise when the occurrence of some events cannot be detected. The considered problem then consists in finding all the states in which the system may be when an observed...

摘要:Abstract(#br)The propagation of information and innovation in social networks has been widely studied in recent years. Most of the previous works focus on solving the problem of influence maximization, which aims to identify a small subset of early adopters in a social network to...

摘要:Abstract(#br)The main contribution of this paper is a novel distributed algorithm based on asynchronous and randomized local interactions, i.e., gossip based, for task assignment on heterogeneous networks. We consider a set of tasks with heterogeneous cost to be assigned to a set...

摘要:Abstract(#br)This note shows by means of simple counterexamples that some key results presented by Luo et al. on the synthesis of maximally permissive supervisors based on the Uncontrollable Transition Gain Transformation method are incorrect. As a result, the transformation of i...

摘要:Abstract(#br)In this paper we propose a novel algorithm to solve the discrete consensus problem, i.e., the problem of distributing evenly a set of tokens of arbitrary weight among the nodes of a networked system. Tokens are tasks to be executed by the nodes and the proposed distr...

摘要:Abstract(#br)This paper deals with the enforcement of nonlinear constraints on Petri nets. A supervisory structure is proposed for a class of nonlinear constraints. In order to enforce a nonlinear constraint on a Petri net, we propose a transition transformation technique to repl...
