11. Semi-markov models of systems with fuzzy parameters [№2 за 2012 год]
Authors: Глушко С.И., Бояринов Ю.Г.
Visitors: 8042
The limitations of existing approaches to the construction and use of semi-fuzzy models for the analysis of the functioning of systems are considered. The main classes of fuzzy functions, which should be used as a fuzzy mappings in constructing models of semi-Markovian systems with fuzzy parameters, are allocated and described. An approach to the analysis of semi-fuzzy models, regardless of which of the options are clear, and which – fuzzy are presented.

12. Algorithms of the biosynthesis process parameters estimation [№2 за 2012 год]
Author: Gordeeva Yu.L.
Visitors: 8997
Three algorithms have been presented in this report: the algorithm for calculation of process parameters when substrate concentration and dilution rate are known; the algorithm for determination of substrate concentration in the range of given values when the productivity is maximum; the algorithm for evaluation of dilution rate in the range of given values when the productivity is maximum. Numerical examples of the implementation of these algorithms have been considered.

13. Cae for streams modeling and dynamics of fish movements passing through fishways [№2 за 2012 год]
Authors: Горячев В.Д., Зимка М.C.

The article speaks about processing of flight plan information in air traffic planning system and advantages of multithreading data processing for improvements of system performance.

15. Experimental acknowledgement of consistency of estimations of difficulty of tasks of a test [№2 за 2012 год]
Author: Елисеев И.Н.

The results of numerical experiments confirmed the consistency of maximum likelihood estimates of the latent parameter «difficulty of the task» Rush's dichotomous one-parameter model at the fixed number of tasks of test L of identical test difficulty and indefinitely increasing the sample size of students N. It is shown, that under the same conditions of estimation of level of preparation of n-th student, calculated from the permissible dichotomous response matrix, tend in probability to their original estimates .

16. Models of inference in the expert systems of psycho-physiological diagnostics [№2 за 2012 год]
Author: Ермаков А.Е.
Visitors: 8531
The different models of straight inference of diagnostic conclusion are considered in the class of the expert systems of psychological and physiological diagnostics, created within the framework of the problem-oriented computer-aided technology, and also features of organization of calculations in these expert systems at the use of the examined models of conclusion.

17. Vulnerability of web content protection of type HTML Guardian [№2 за 2012 год]
Author: Ermakov D.G.

The task of overcoming of protection of information from copying, similar to ProtWare's HTML Guardian, is considered. To solve the task we suggest using standard means of MS Windows: Windows PowerShell scripting language and browser MS Internet Explorer. It is shown that it is impossible to protect a web page content, since the browser receives the non-encoded HTML-code, and there is a simple and fast method to receive this non-encoded code by means of PowerShell.

18. Program choice of technological regimes of discrete-continuous casting of non-ferrous metals and their al-loys [№2 за 2012 год]
Authors: Zhiganov N.K., Fomina, E.E.
Visitors: 10870
We consider the program, for modeling, optimization and the choice of technological regimes of continuous and discrete-continuous casting of non-ferrous metals.

19. Method of construction the security model of automated systems [№2 за 2012 год]
Authors: Zhukov V.G., M.N. Zhukova, Золотарёв В.В., Ковалев И.В.

Proposed a method of constructing security model for automated system in the protected execution. Considered the work stages at security model building. Shown the generalized scheme of a software system of automated security model building.

20. Method of construction the security model of automated systems [№2 за 2012 год]
Authors: Zhukov V.G., M.N. Zhukova, Стефаров А.П.
Visitors: 18015
Proposed a method of constructing the violator’s model of unauthorized access in to the auto- mated system. Considered a procedure for classifying violator’s, which performs unauthorized access to automated system.
