The use of Petri nets for modeling pipelined processors [PDF]

open access: yes, 1987
This paper discusses the use of Petri Nets for modeling and analyzing pipelined processors. Petri Nets are particularly well-suited to modeling the synchronization, buffering, resource contention and delicate timing so common in pipelined processors ...

On the Model of Computation of Place/Transition Petri Nets

open access: yes, 1994
In the last few years, the semantics of Petri nets has been investigated in several different ways. Apart from the classical "token game", one can model the behaviour of Petri nets via non-sequential processes, via unfolding constructions, which provide ...

Parallel 3D Bioprinting on SLIPS‐Microarrays

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

T-invariants for jumping Petri nets [PDF]

open access: yesComputer Science Journal of Moldova, 2001
This paper introduces the notions of T-invariants for the class of finite jumping Petri nets, and extends the results concerning T-invariants from classical Petri nets.

Petri net equivalence [PDF]

open access: yes, 1987
Determining whether two Petri nets are equivalent is an interesting problem from both practical and theoretical standpoints. Although it is undecidable in the general case, for many interesting nets the equivalence problem is solvable.

Nanodiamond Quantum Sensors for Probing Free Radical Biology

open access: yesAdvanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Time Extensions of Petri Nets for Modelling and Verification of Hard Real-Time Systems [PDF]

open access: yesComputer Science, 2002
The main aim ofthe paper is a presentation of time extensions of Petri nets appropriate for modelling and analysis of hard real-time systems. It is assumed, that the extensions must provide a model of time flow an ability to force a transition to fire ...
