Introduction to the Atoment language

The Atoment language is a domain-specific language of development for program verification methods. It is used in the multilanguage software system Spectrum of rapid development and testing of verification methods. The easy-to-use specialized language allows a user of the system to describe verification methods in a natural notation, verify algorithms...

An extension of a visualization component of ontology based portals with visual analytics facilities

The process of development of an ontology-based knowledge portal and creation of its content is time-consuming and laborious. The lifetime of such portals is sufficiently long and they collect a great volume of valuable information. This information can be analyzed from various points of view. This paper describes an extension...

Methods of syntactic analysis and comparison of constructions of a natural language oriented to use in search systems

This work is dedicated to an actual problem of efficient information search in the Internet. The work is based on the algorithms of sentences comparison taking into account the schemes of syntactic analysis generated by Link Grammar Parser software. The main idea is that syntactic diagrams give us a primitive...

Error-tracing axiomatic semantics for C-kernel

The classical Hoare logic links separate verification conditions (VCs) to linear paths of a program. The real verification condition generators (VCG) link VCs to line numbers at best. It can be insufficient, since VCs contain information neither about the evaluation order nor about correspondence between their fragments and specific operations....

Performance preserving equivalences for dtsPBC

For a discrete time stochastic extension dtsPBC of finite Petri box calculus (PBC) enriched with iteration, we define a number of stochastic equivalences. They allow one to identify processes with similar behaviour which are differentiated by the too discriminate semantic equivalence of the calculus. We investigate which is the weakest...

An approach to development of the decision support system for enterprise with complex technological infrastructure

The paper presents an approach to development of a system that supports decision-making for tasks aimed to reduce power consumption and enhance the environmental safety of a large-scale enterprise with a complex technological infrastructure. The architecture and operating principles of this system are discussed. Adjustment of the system to the...
