In this paper, a software package for cellular automata simulation, 2D/3D visualization with a shared work support system was introduced, that was designed considering the needs of researchers in both local and virtual laboratories. As an example of cellular automata, abelian sandpile model has been chosen. An appropriate software package has been developed using Microsoft .Net and C# enabling users to work at the same time on the same models independent of the geographical location of users within the public network.
We study the models of rumor spreading and invasion bond percolation aimed at the revelation of possible connections between them. Rumor spreading model describes the dissemination of a rumor due to the periodical repetition of sequential phone calls, whereas the invasion bond percolation refers to the spread of liquid in the porous environment. During a round of the rumor spreading, each node performs a call only once, meanwhile transmitting all the information that it knows at the moment of the call to its neighbors. The rumor reaches the receiver node during one round if there is a chain of successive calls between the source of the rumor and that node. The sequence of calls is taken uniformly at random from the set of all possible sequences (permutations of nodes). We compare the propagation of the rumor spreading with the invasion bond percolation in order to put forth necessary improvements of the percolation rules to map one model onto another, and vice versa
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
