Документ About One Model of Consecutive Qubit Binary Testing(V. Karazin Kharkiv National University, 2010) Thawi, M.; Zholtkevych, G.Qubit binary tests models are considered in the paper. For each binary test the state of compound quantum-classical system is associated. Formulas for density matrices transformation under binary test are obtained. Method for computing probabilistic characteristics of testing outcomes is proposed. Class of probabilistic measures on testing outcome sequences space is described.Документ Discrete Dynamical Modeling of System Characteristics of a Turtle's Walk in Ordinary Situations and After Slight Stress(2011) Bespalov, Yu.; Gorodnyanskiy, I.; Zholtkevych, G.; Zaretskaya, I.; Nosov, K.; Bondarenko, T.; Kalinovskaya, K.; Carrero, Y.Документ Hierarchic Decomposition of Pre-machines as Models of Software System Components(Державне підприємство «Центральний науково-дослідний інститут навігації і управління», 2011-12) Zholtkevych, G.; Perepelytsya, I.In this paper we consider a model of system interaction with the environment, which allows us to forget its full protocol from time to time. Mathematical models of such interactions are pre-machines. We showed that the machines can be completely described in terms of some special class of digraphs. An approach to analyzing the structure of pre-machines in terms of their derivatives series is offered.Документ On some class of mathematical models for static analysis of critical-mission asynchronous systems(2011-12) Zholtkevych, G.; Perepelytsya, I.A mathematical model of asynchronous software system is considered in the paper. This model bases on the notion abstract finite pre-machine which generalizes the notion abstract finite automaton. In contrast to generally accepted models the model proposed in the paper makes possible to specify more complex system behaviour than it is provided by finite automata models. Specifically, live-lock anomaly can be specified using the notion pre-machine. Authors adduce the criterion of live-lock existence and illustrate it by example.Документ On the structure of quantum channels(Kharkov: V. N. Karazin national university, 2009) Thawi, M.; Zholtkevych, G.7-а Міжнародна алгебраїчна конференція в Україні: тези доповідей (18-23 серпня 2009 року, Харків)/ Відп. ред. Г. М.

The empirical data demonstrates the existence of different intrapopulation strategies by partitioning a sample of individuals into two groups on the basis of their body size at a given age and comparing selected groups in terms of factors such as growth rate, life span, females’ fecundity and the age at which breeding commences. Then by using simulation modeling, we study the probable importance of intrapopulation ontogenetic strategies for the stability of Pelophylax esculentus complex HPS.Документ Sustainable coexistence of the parental species and hemiclonal interspecific hybrids is provided by the variety of ontogenetic strategies: simulation HPS Pelophylax esculentus complex preliminary results(Daugavpils University, 2015) Shabanov, D.; Usova, O.; Kravchenko, M.; Leonov, A.; Korshunov, O.; Mair, Q.; Meleshko, O.; Newman, J.; Vladymyrova, M.; Zholtkevych, G.
