Abstract
The application of the bioinspired methods for handling the cryptanalysis problem of the asymmetric encryption algorithms on the basis of the composite number factorization is considered. The algorithms of ant and bee colonies for the composite number factorization by the definition of the integer divisor to the specified accuracy in the stated interval are adduced. The properties of the methods presented, including the efficient parallel feasibility, are described.

Abstract
The mathematical simulation of the interaction of kinematic perturbations of the tool shape-generating movement trajectories and the workpiece is considered. They de-fine one of the key factors determining the parameters of part manufacturing accuracy. The data for the effect not only of the interacting dynamic subsystems parameters, but also of the geometrical parameters of the cutting tool on the perturbation movements is resulted.

Abstract
The scientific basis for the dynamics and mechanical-mathematic simulation of the transport technological machines for agriculture as the multivariable oscillatory systems with holonomic and nonholonomic constraints under the non-stationary random perturbations is described. It has permitted to represent the output variable dynamic systems of the agricultural machines, on the ground of Lagrange multiplier method, in matrices and graphically.

Abstract
The control method of the initial arc ignition in the gas-shielded welding is offered. It is based on the short-circuit current limitation after heating the wire stick-out with the metal passing current to the plastic state for the time of the wire burnout approach point at the stick-out-to-work distance not exceeding the arc breaking length. The dependences describing the conditions necessary and sufficient for the reliable establishment of the welding process after the first wire-work contact are experimentally investigated and analytically determined.

Abstract
The theoretical and experimental investigations on the development features of the structural heredity of high-speed steels under the hypernonequilibrium phase transitions are carried out. The average austenite grain diameter after different options of the volume and surface heat treatment, that permits to estimate the temperature interval of steel hardening heat, is determined.

Abstract
Some mechanisms of determining the flexible rotor axis elastic buckling in the eigenmode bend and thereto related distributed unbalances are specified through its dynamic simulation. A new method of identifying the model parameters and balancing of such rotors in the eigenmode bend is evolved.

Abstract
The problems of parts of speech interaction with the application of field theory revealing the systematic ties within the vocabulary system, the existence of synchronic and diachronic, implicit and explicit, syntagmatic and paradigmatic, direct and indirect, motivated and idiomatic relationships between language items, dependence of word-building meaning of any derived word on a structural, semantic character of its word-building bases giving a wide-ranging analysis of parts of speech interaction in the linguacreative activity of people are considered.

Abstract
Some sociocultural and social-psychological personality characteristics in the transitive society are analyzed. The effect of such determinants as apathy and vacuum on the human behaviour is shown. The characteristics of ‘mass man’, ‘resting man’, ‘paradoxical man’ are presented.

Abstract
The ideological process of Modern age expressed in the advent of the specialized social and political ideology is investigated. The point that planning development prospects of the Russian society assumes coping with the unilateralism of the social and philosophical conceptions forming the theoretical basis for the future-oriented ideology is established.

Abstract
The process of the individualization of time as a special case of the temporal organization of the social agent’s life activity in the modern society and culture is analyzed. It is shown that the productive indivi-dualization of time is restricted to the latent impact of the objective social structures through imposing ready-made relation schemes to time and disturbing the collective rhythms of life activity.

Abstract
Industrial engineering techniques are total operations and methods for the production or rendering services. The selection of the method and industrial engineering techniques — job shop-type, batch or repetitive — is primarily subject to the industrial scale. The manufacturing programme making, batch quantity and stock optimization depend on the size of the customer orders, and are determined by the diagnosis effectiveness. Production engineering processes are completed in the planning (including communication), forming the closed model of all productive processes of the enterprise.

Abstract
Industrial enterprises in the market economy function amid the crisis. The risk management problem has been interested scientists since A. Smith. However, risk management has become an object of close attention for the Russian scientists and experts in recent decades, inasmuch as the effective business development, financial stability, competitiveness and investment attractiveness of the enterprises depend largely on the risk management effectiveness.

Abstract
The modern concept of the machine-building enterprise development involving the idea of the systematic umbrella approach plays a crucial role in the economy. The approach permits the researcher to study the enterprise system behaviour as an integrated mechanism, rather than to concentrate upon its single elements. The approach derives from the recognition that should every single element or subsystem have high productiveness and operativeness, then the total system condition could be nonoptimal just due to the failure in the quality synergies between its parts. So, the discussed systematic approach becomes an ever more significant research method in economics.
