Well-formed Petri Net
Well-formed Petri nets are a Petri net class jointly elaborated between the University of Paris 6 (Université P. & M. Curie) and the University of Torino The University of Turin (Italian language, Italian: ''Università degli Studi di Torino'', UNITO) is a public university, public research university in the city of Turin, in the Piedmont (Italy), Piedmont region of Italy. It is one of the List ... in the early 1990s. It is a restriction of the high-level nets (or colored Nets) introduced by K. Jensen. The main advantage of Well Formed Nets is the notion of symbolic reachability graph that is composed of ''symbolic states''. A symbolic state is a state representing several concrete states in the state space of the system described by the Petri net. So, much larger state spaces can be represented (the gain factor can be up to exponential). This notion of symbolic state space requires that only a limited set of operators are available (identify, broadcast, successor and predece ...

Petri Net
A Petri net, also known as a place/transition (PT) net, is one of several mathematical modeling languages for the description of distributed systems. It is a class of discrete event dynamic system. A Petri net is a directed bipartite graph that has two types of elements, places and transitions. Place elements are depicted as white circles and transition elements are depicted as rectangles. A place can contain any number of tokens, depicted as black circles. A transition is enabled if all places connected to it as inputs contain at least one token. Some sources state that Petri nets were invented in August 1939 by Carl Adam Petri—at the age of 13—for the purpose of describing chemical processes. Like industry standards such as UML activity diagrams, Business Process Model and Notation, and event-driven process chains, Petri nets offer a graphical notation for stepwise processes that include choice, iteration, and concurrent execution. Unlike these standards, Petri nets hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Torino
The University of Turin (Italian language, Italian: ''Università degli Studi di Torino'', UNITO) is a public university, public research university in the city of Turin, in the Piedmont (Italy), Piedmont region of Italy. It is one of the List of oldest universities in continuous operation, oldest universities in Europe and continues to play an important role in research and training. It is steadily ranked among the top 5 Italian universities and it is ranked third for research activities in Italy, according to the latest data by ANVUR. History Overview The University of Turin was founded as a ''studium'' in 1404, under the initiative of Prince Louis of Piedmont, Ludovico di Savoia. From 1427 to 1436 the seat of the university was transferred to Chieri and Savigliano.

It started to gain its modern shape following the model of the University of Bologna, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEEE Computer Society
The Institute of Electrical and Electronics Engineers (IEEE) is a 501(c)(3) professional association for electronic engineering and electrical engineering (and associated disciplines) with its corporate office in New York City and its operations center in Piscataway, New Jersey. The mission of the IEEE is ''advancing technology for the benefit of humanity''. The IEEE was formed from the amalgamation of the American Institute of Electrical Engineers and the Institute of Radio Engineers in 1963. Due to its expansion of scope into so many related fields, it is simply referred to by the letters I-E-E-E (pronounced I-triple-E), except on legal business documents. , it is the world's largest association of technical professionals with more than 423,000 members in over 160 countries around the world. Its objectives are the educational and technical advancement of electrical and electronic engineering, telecommunications, computer engineering and similar disciplines. History Orig ...
