Problems with precise estimation of volume and weight flows of compressed air, when investigating pneumatic automation elements’ and devices’ characteristics, are widely known. Precise compressor-doser was designed on the basis of pneumatic cylinder; it allowed to give objective estimation of weight flow of compressed air, when determining flow-drop characteristics of orifice meters. It was shown that flow gages had stable linear characteristics in the case when estimation of flow based on the measurement of the pressure at the entrance of the orifice meter at the stage of exhaustion.

The dynamic diagnostic model of the mount of the winding in slot of the stator core of a powerful turbo-generator is constructed. The range of possible values of parameters of model is defined. Dynamics of the symmetric distributed vibro-impact system "winding - core" for various values of system parameters and external exciting forces is studied. Tendencies of change of parameters of the signal of shocking forces with development of defect are defined. Calculation of the spectra of signals of shocking forces that excite the vibroacoustic vibrations of the stator design is carried out.

Practicable methods of fastening of the composite details with metal parts of designs were researched. The results of tests were presented; empirical dependence for the forecast of working efficiency of such joints was proposed. Regression and dispersion analyses of obtained test data were carried out. Future development of such joints was outlined.

The case of thin-walled workpiece fixing with n cams was considered. Algorithm of calculation of main parameters when fixing the thin-walled workpiece. Proposed algorithm differs from known algorithms because it takes the size of contact area and diagram of contact pressure into account. Dimensionless graphics were plotted for the case when the workpiece is fixed with three cams. These graphics allowed to determine contact half-angle, form error of workpiece when it’s fixed with three cams and movement of median surface’s points of workpiece under the cam and strictly between cams. The example of the calculation was included in this article.

The results of EMS development in the form of Euler dynamic equations with variable matrix of inertia tensor for analytical and experimental investigation of EMS dynamics with distinct resonating characteristics were presented in the article. Continuous model is likely suitable for large spacecrafts. Considered methods of vibration-based diagnostics are based on the suggestion that model or enumeration of models of diagnosable subject is known. The goal of diagnostics is the determination of this model’s parameters.

The general provisions of the fuzzy interpolation were considered for the case when the values of the grid functions were defined as fuzzy numbers. Attention was paid to Newton's interpolation, where fuzzy power polynomial was used to reach the same goals. The existence conditions of strong, weak fuzzy Newtonian interpolation and its absence were given. Examples were given for the case when the power polynomial was the first-degree polynomial used for fuzzy interpolation of two fuzzy numbers. Spline interpolation is usually used to eliminate the edge effect at the end of the specified period. So the task of obtaining spline from fuzzy data and analysis of this data for the type of spline (strong, weak or lack of a fuzzy spline) is very important.

Concepts of complex that belongs to class of expert systems and designed for conduction of numeric experiments (simulation) in order to analyze productivity (timing data) indexes of distributed systems of data processing (DSDP) were considered. New class of analysis model of DSDP’s timing performances was developed in this work with optimization mechanisms of queries to distributed database taken in the account. Application of the decision-making process, based on holistic selection of architecture type was also developed. If frame of expert system is connected with SQL operator, then frames unite into network that corresponds to the sequence of SQL operators’ execution. Different resources of computer network are used when SQL operators are executed that is frame network goes into resources of computer network.

Different problems were solved while developing schemes of databases for ADSDP; they included description of nodes, channels, DSDP topology, virtual communication channels and their characteristics; determination of node configuration and channel configuration based on the СMAT registries; distribution of transactions with description of SQL-queries and tables of DSDP databases over nodes; storage and maintenance of components of devices’ load ratio and execution time of transactions (these components are used for maintenance of ES explanation mechanism); maintenance of ADSDP data base integrity.

The theory of acoustic resonator based on the corrugated tubes was briefly discussed. For simplicity, situation with medium at rest inside a corrugated tube was considered. Classical solutions for the resonator were obtained. It was shown that described structure could serve as an acoustic analogue of the optical resonator. Generalizations for the case of moving medium were made.

The author analyzed the process of optical soliton’s occurrence due to the balance between two competing physical processes; they are dispersion spreading of light pulse and phase self-modulation (PSM), which occurred from the non-linearity of optical signal’s propagation medium (Kerr effect). The method of compensation of the optical signal’s chromatic dispersion in the fiber was proposed. Analytical expressions of mathematical expectation and dispersion of repetition period of solitons and value of soliton signal were obtained from random time of pulse’s arrival to detector. Obtained data must be taken into consideration when calculating signal-to-noise ratio in soliton fiber-optic transmission system (FOTS). The analytical expressions of time response, amplitude-frequency characteristics (AFC) and phase-frequency characteristics (PFC) were obtained for different input signals: for Dirac delta function and for Gaussian. These characteristics were conditioned by Rayleigh backscattering.

Method of convergence acceleration for iterative solutions of SLAE from electrical network modeling systems was proposed. This method was based on the neutralization of the dominant characteristic values of transfer matrix. By the example of AC electrical networks’ computation defined with matrices with complex numbers; the dependence of iteration number of Gauss-Seidel method on the number of neutralized roots was shown. Calculated data corresponded well to theoretical convergence estimate obtained from characteristic equation roots. The ability of additional convergence acceleration by means of the root neutralization was shown in the successive over-relaxation method.

The developed criteria and indicators had theoretical and practical importance for further studying of the problems of vocational education.

New system of physical quantities and dependences that could be used in teaching physics was presented in this article. Author described dimensional fundamentals of multilevel system of physical quantities and principle of determination and visualization of dependences, and also provides samples of such visualization for three divisions of physics: mechanics, thermal and emitting quantities and electromagnetic quantities and dependencies.The most valuable part of the system is that its users who understand the uniqueness of the system’s multilevel nature and formal rules of exploring dependencies could easily find dependences which present natural relationships. This way they can avoid thoughtless memorizing of numerous physical formulas. Furthermore, the skill of creating formulas from other formulas - that can be difficult for engineering students - becomes less important and not necessary.
