This method allows to analyze behavior of essentially multivariable systems through the dynamic behavior of its basic components, i.e., subsystems (both linear and nonlinear), that have a reduced order state-space. Such approach allows to bring out strict proof of existence of free and forced periodical motions. In most cases the approach allows to complete “partition” of the space of parameters into areas corresponding to qualitatively different dynamic behaviors.","PeriodicalId":110366,"journal":{"name":"2015 International Conference \"Stability and Control Processes\" in Memory of V.I.

The results of calculations are presented in graphical form. We calculate the pressure distribution of the viscoplastic oil layer in the problem of stationary filtration. It is assumed that the process of filtering is radially symmetric. The model of finite layer is used. Predetermined pressure is maintained on the boundary of the layer. Oil is considered weakly fluid and its density is determined by formula. At the same time it is assumed that oil viscosity depends on pressure gradient and this dependence is approximated by the sigmoid function. The proposed problem is solved by the method of finite differences using Newton's method to solve the nonlinear system of equations.","PeriodicalId":110366,"journal":{"name":"2015 International Conference \"Stability and Control Processes\" in Memory of V.I.

The notions of reducible and irreducible exponents collections and uniformly reducible set of collection are introduced. Linear programming problems series solving is offered for investigation of uniformly reducibility of set. An algorithm optimizing the computations by means of special subset of series construction is elaborated. The search of reducing permutation is replaced by search of special Hamiltonian cycle in complete graph. The sufficient conditions of reducibility and irreducibility are obtained. The examples of irreducible collections are constructed. The methods of constructions of new collections from old ones are given. For the above mentioned class of Schwartz-Christoffel integrals the Paatero's theorem about sufficient condition of univalence is generalized.","PeriodicalId":110366,"journal":{"name":"2015 International Conference \"Stability and Control Processes\" in Memory of V.I.
