Using floorplans for software visualization

In this article we consider requirements to visualization of semantic properties of programs appearing in the reengineering process when use of hierarchical ordering is an appropriate way to visualize the information of interest. We consider two algorithms of graph placement that implement geometrical inclusion of object hierarchy. They use (non)slicing...

SAT vs. SMV for automatic validation of tabular property of superintuitionistic logics

This paper considers theoretical background and experimental compar- ison of two approaches to automatic recognition of tabular property of superintu- itionistic logics. A principle opportunity for automatization is based on theoretical results of L.L. Maksimova that were obtained in 1973{2003 and their algorithmic interpretation that was developed recently by P.A....

Sisal 3.1 language structures decomposition

The paper describes equivalent transformations of Sisal 3.1 language structures in detail. The programming language Sisal 3.1 is based on Sisal 90. Transformations are aimed to to decomposition of complex language structures into more simple ones that can be directly expressed by an internal representation IR1 based on an intermediate...

Iteration in discrete time stochastic Petri box calculus

In the last decades, a number of stochastic enrichments of process algebras was constructed to specify stochastic processes within the well-developed framework of algebraic calculi. In [26], a continuous time stochastic extension of finite Petri box calculus (PBC) was proposed and called sPBC. The algebra sPBC has...
