The paper presents calculations pertaining to survivability of NPS load-carrying elements with respect to crack-resistance. These calculations reflect their resistance ability to actions of mechanical, thermal, hydro-dynamic, electro-magnetic  loads in the case when there are defects in the elements (initially technological defects or operational ones). The most dangerous defects are micro- and macro-cracks that create maximum high concentration of stresses and deformations.

If a defect unexpectedly arises in the direction of supply while working a «free» curve being distinguished by a arbitrary curvature and small value twisting from the given ones then there will be worsening of cutting process that will lead to surface defects of the machined surface or tool break down. A method of wave analysis has been used for an experimental study of power in specific frequency bands and a minimum cutter damage has been obtained which with power on a drive motor makes it possible to control supply, restoring the condition of cutting. A technical novelty of automatic control method has been proposed according to instantaneous defect by means wave change on a drive motor. The problem of quantitative assessment of machined surface defects has been successfully solved in the paper.

As an example of welding control the paper considers operational principles and contains a comparison of classical and neuro-supply line methods for welding process control. Main advantages of neuron-supply line control, namely: high failure resistance, operational parallelism of data processing and approximation of any smooth functions are shown in the paper. Its disadvantage is that it requires high calculative power (DSP processor or PLIS) and it is necessary to carry our setting procedure of neuro-supply line.

The paper deals with an efficiency estimation of automated mechanical transmission at off-line simulation stage. A simulation model of a vehicle with an automated power unit for gear change control strategy research has been developed in the paper. The paper contains a complex mathematical description of the analysis scheme. It allows adequately to react to structure reorganization and parameter change of the dynamic system at an application of external disturbances from the road and a driver. A peculiar feature of the developed software that is an opportunity of real-time modeling. This decision enables to estimate automated mechanical transmission operation at a wide spectrum of the driver’s actions. The experiment on a driving simulation of a heavy truck with 40000 kg GCW on a road climb has been carried out. The estimated values of driving on a route have been compared  during gear changes in automatic and command modes by drivers of various qualification. The paper contains conclusions about efficiency of the analyzed gear change control strategy. A strategy for improvement of automated mechanical transmission controlling algorithms has been proposed in the paper.

The paper considers principles of execution and methods for investigation of adaptive micro-processor protection of distributive systems with one- and two-side supply. Adaptive current protection  for the systems with one-side supply controls a moment  of non-symmetric  damage  initiation and automatically operate current of measuring elements. Systems with two-side supply presuppose combined usage of methods for determination of damage places and conventional method for execution of protection.

The formulated problem refers to the problems of combinatory (discrete) optimization. Methods of «branches and boundaries» or dynamic programming are applied nowadays for solving problems of this type. These methods are not considered as universal ones because they greatly depend on description  of  solution feasible area. As a result of it it is not possible to develop a universal software for solving any assignments which can be formulated as problems of combinatory optimization.

The presented network model of the investigated problem does not have above-mentioned disadvantages and an algorithm is proposed for solving this problem which admits a simple programming realization.

The paper studies problems pertaining to development of intellectual scientific search systems from the point of view of epistemology as a science on knowledge, its functioning and development. The most important epistemological postulates are determined in the paper and these postulates serve as a basis for an analysis of intellectual technologies of creative search and knowledge formation. Using a systematic approach to study of intellectual technologies of the innovation search the paper considers division of knowledge system in its components – properties of an object to be investigated (separate knowledge clusters). The mentioned approach and adopted biophysical analogies in the investigation of the intellectual technology on knowledge formation have made it possible to identify one of the key epistemology problems in respect of intellectual systems that is an initial uncertainty of scientific search purpose. In this connection a structure of value-orientated knowledge search in the intellectual medium is determined in the paper. The paper also analyzes process pertaining to transformation of value orientation of scientific search into its purposeful development. A role of intellectual systems of scientific search concerning knowledge synthesis of various cognate practices is considered in the paper. The paper proposes a variant pertaining to creation of generalized information image of the studied phenomenon in the intellectual medium on the basis of frame models of knowledge systems from various cognate practices.
