due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...

This poster presents a tool for the modular construction of Petri net transducers by means of several composition operations as for example union, concatenation, closure, parallel and synchronous product and language composition. There are exports to PNML and several graphical output formats. For the implementation, we use the SNAKES framework, which is a Python library supporting the rapid pro...

Fuzzy Petri net; Fuzzy logic; DNA sequencing; Modeling and simulation Abstract In this paper, a fuzzy Petri net (FPN) approach to modeling fuzzy rule-based reasoning is proposed to determining confidence values for bases called in DNA sequencing. The proposed approach is to bring DNA bases-called within the framework of a powerful modeling tool FPN. The three input features in our fuzzy model-t...

This paper gives a solution of the synchronic distance between any two transitions in a fair Petri net. In order to describe the synchronic distance between two transitions more accurately, the concept of weighted synchronic distance is adopted. The solution method is firstly to add a weighted observe-place between two transitions, and a net system with a weighted observe-place is constructed b...

As mobile computing becomes widespread, so will the need for digital document delivery by hypertextual means. A further trend will be the provision of the ability for devices to determine where they are, e.g., through the inclusion of GPS sensors, as will the need for devices to operate on heterogeneous networks. Consequently, hypertext systems supporting these devices will benefit if they also...

Despite their attractive properties, networked virtual environments (net-VEs) are notoriously difficult to design, implement and test due to the concurrency, real-time and networking features in these systems. The current practice for netVE design is basically trial and error, empirical, and totally lacks formal methods. This paper proposes to apply a Petri net formal modeling technique to a ne...
