Universality of algorithms predicting strong events in complex systems
A.B. Shapoval, M.G. Shnirman

In spite of hypothesis claiming non-predictability of models with self-organized criticality (SOC), this paper for the first time gives evidence that strong events in a SOC-model of earthquake occurrence (of the Manna type) are predictable with certain efficiency. Some quiescence underlies the prediction. The error diagram exhibits prediction efficiency.

Keywords: self-organized criticality, prediction, error diagram

N.I. Vitiska, V.V. Gudilov, S.V. Gudilov

The opportunities of application existing hardware reconfiguring structures at the organization of switched connections between elements of multiprocessing systems by the example of parallel performance of genetic operators crossover and mutation are investigated for. Changed approach of the organization of multistage network MCRB in conditions of reduction quantity steps with simplification structure management is shown. The example of construction a switching cell is resulted in view of requirements solved problems.
Keywords: multistage networks; genetics algorithms; crossover; mutation; MCRB; Truncated MCRB.

Dynamical Simulation of Rigid and Flexible Bodies System in EULER
V.G. Boykov, A.A. Judakov

The article reveals main simulation concepts implemented in EULER, a software product for automated analysis of multi-component mechanical systems. Formal representation of a mechanical system and general principles of forming and solving motion equations are shown. Dynamical equations for the flexible bodies undergoing small deformations and moving as parts of a mechanical system are derived. Finite-element method, Craig-Bampton matrixes reduction method, and more general approach than the ones known from the literature are used to derive the equations.

Keywords: mechanical system, motion equations, constraints equations, flexible body, finite-element method, Craig-Bambton method.
