Mathematical models of phenomena in electrical contacts
The different methods of solution of mathematical models describing phenomena in electrical contact systems by arcing are presented in the book. All phenomena at contact opening and closure are considered as consecutive stages including the initial stage of Joule’s heating, appearance and explosion of a liquidmetallic bridge, ignition, evolution and extinction of the electrical arc in metallic and gaseous phases. Step by step the mechanism of the arc erosion due to vaporization, as well as the new mechanisms of erosion due to thermo-capillary convection and erosion in solid state due to thermo- elastic stresses are introduced and considered. Mathematical models of arc floating, bouncing and welding, arcto-glow transition have practical applications in design of vacuum circuit breakers and other electrical contact systems.
Most of above models are based on the boundary-value problems for the systems of partial differential equations of parabolic and elliptic types in domains with free boundaries, and included the phase transformations such as melting and evaporation. For their solution were elaborated, in particular, the method of majoring functions, methods with using integral error functions, heat polynomials, dual integral equations.
Results of the modeling can be used for development of new circuit breakers and other electrical contact systems.
Researches, results of which are presented in the book, are supported by the Grant 5133/ГФ4 – «Methods of special functions for the solution of free boundary problems and their applications for modeling of heat and mass transfer at electrical arc phenomena» awarded by the Science Committee of the Ministry of Education and Sciences of Kazakhstan.

Equivalences for behavioural analysis of concurrent and distributed computing systems
Academic Publisher "Geo",
Novosibirsk, 2007
In the monograph, a wide range of behavioral equivalences has been proposed and investigated on the well-known models for concurrent systems specification and analysis such as Petri nets and process algebras. The equivalence relations have been explored on subclasses and extensions of the models: time and stochastic Petri nets and stochastic process algebras. On Petri nets both with and without silent transitions and their subclasses a wide set of basic, back-forth and place behavioural equivalences were proposed and investigated in the semantics ranged from interleaving to true concurrent as well as from linear to branching time ones. On time Petri nets both with and without silent transitions and their subclasses a number of time, untime and regional equivalences were proposed and investigated in interleaving and step semantics as well as in trace and bisimulation ones. Semantic equivalences of standard and stochastic process algebras are investigated, and a coherence between them and the net equivalence relations is clarified. An algorithm of automatic formula comparison for the semantic equivalence is designed and implemented. For graduate and post-graduate students and researchers interested in theoretical computer science, in particular, formal modeling and analysis of behavioural properties of concurrent systems and processes.
Keywords: standard, time and stochastic Petri nets, subclasses, standard and stochastic process algebras, invisible transitions and actions, behavioural and semantic equivalences, bisimulation, temporal and probabilistic logics, reduction, refinement and composition, congruence, axiomatization, term rewrite systems, implementation.
The book can be purchased in the internet shop of SB RAS Publisher or in the Akademkniga bookshop (22, Morskoj pr., 630090 Novosibirsk, Russia. Phone: +7 383 330 09 22).

Verification of Estelle Specification of Distributed Systems using Coloured Petri Nets
This work is devoted to research dealing with automated
constructing net models of Estelle specifications and developing
verification tools of the models. We consider Estelle specifications
with delay-clauses and priorities, but without dynamic constructions.
The specifications allows to represent a considerable class of
communication protocols. We use coloured Petri nets extended by
priorities and Merlin's time concepts as the net models. This work
describes a method of translating the Estelle specification into
the net models, its implementation and the system NetCalc for editing
and simulating the models. We present experimental results of net
modeling and simulation for versions of the following well-known protocols:
sliding window, ring, connection and InRes.
