The definition of the term and the terminological system is interpreted. The contents, structure, characteristics, and the functioning of terms in scientific and technical texts, as well as the problems of the overall composition of technical terminology, specific features of synonymy and polysemy, are presented. The description of the contextual meaning of some groups of words of the common national language, used in technical literature, is given. The sources and ways of formation of new terms, the appearance of proper names, technical abbreviations, and acronyms in science and technical texts, are set forth. Keywords:

Presently variable computeroriented mathematics systems (CMS) [8] are used for learning of control systems mathematics description forms for education software. Matlab mathtematic system sets off these systems [10]. The modeling package of block dynamical systems (Simulink) enter into this system. In this article the design technique of the Spektr_SM extension package [9] for Simulink package is considered. The Spektr_SM extension package is based on MLSY_SM extension package [8] for CMS Matlab. The functional blockscheme of control systems permits to introduce setting up the problem. The Spektr_SM extension package admits of analyze linear, nonstationary, determinate and stochastic, discrete, continuous, continuousdiscrete control systems in the spectral domain. Characteristics and description of the package are provided. Examples of control systems Smodels construction and results of analysis of these systems based on the Spektr_SM extension package for Simulink package are realized. Keywords: 

A problem vectorvalued criteria optimization is considered in terms of set theory. The basic concept of the approach is a method of formal description of weight coefficients and the method of scalarization by the system of nonequalities. This set allows us to create the integral as well as minmax criterion on the way of solution of simple geometrical problem. Keywords: 

In this article the review of the common modern electronic documentation management systems is given. Classification of the given systems with the description of prominent features of the software products placed in the market is made. For each system the direction and the purposes of their development is described. Keywords: 

The article presents model of building corporate integrated information system is offered by means of integration of systems of a computerassisted design of workpieces with control systems of resources of the factory through a control project data management system. The similar model allows to operate life cycle of a workpiece from a design stage up to a stage of issue of a finished product. Possible modes of integration of systems and also model of a heading of the integrated corporate intelligence system are offered. Keywords:

Methods of measurement rotary and nonstationary derivative lateral movement and their complexes on the dynamic installations established in aeropipes, with linear and angular (around OX and OY) fluctuations of model are submitted. Determined expression of fields of relative speeds and factors of the aerodynamic moments  for flying device (ЛА) in oscillatory flight and for model ЛА at imitation of this flight on installation. Allowable amplitudes of fluctuations of model and a vector of speed of air, allowable values of constant corners of attack and sliding , and also new possible corners are found. Measurements of complexes with new proportions of derivatives (and also only with rotary derivatives and ) in structure of complexes are offered. Keywords: 

The analysis of a technique of measurement of dynamic angular derivatives , and also complexes of rotary and nonstationary derivatives, prepared to their subsequent division, in conditions of required corners of attack and slidings is carried spent. It is established, that measurement at is incorrect, and calculations of a derivative and complexes, are made under erroneous formulas. New formulas for definition are given. Oscillatory experiments are offered at positions of an axis of the fluctuations which are taking place through axes OZ and OY models. As a result of realization of these experiments (together with the experiments connected to fluctuations around of axis OX) unshared complexes may be measured directly without computing operations of reduction of axes.

It is shown that the BelinfanteRosenfeld procedure is incorrect. The standard application of the Lagrange formalism to the general field theory resulted in a mistaken inference about an absence of spin. An expression for electrodynamics' spin tensor density is presented. Keywords: 

Absorption of a circularly polarized light beam without an azimuth phase structure in a dielectric is calculated in the frame of the classical electrodynamics. We consider transferring of angular momentum and energy to the dielectric. Our theoretic result differs from the experimental result of Bishop et al. [6] (Phys. Rev. Let. V. 92, 198104 (2004)). We found that the torque acting on the dielectric consists of a surface part and a bulk part that equal one another. The theoretic value of the total angular momentum of the beam is twice as much as the experimental result. Keywords: 

In the present article a modification of immersed boundary method for numerical solution of transport problems in domains with curvilinear boundaries is proposed. Cartesian grid finite difference method for solving NavierStokes equations for viscous incompressible flows is considered. Implicit extrapolation procedure for approximation of boundary conditions at curvilinear boundary is applied. Numerical solution of test problem for flow in symmetric channel with smooth expansion is carried out. Obtained results are validated by comparison with high precision results, taken as "exact".
