Abstract:The general task of integrated (assembled) design of energy- and resource-saving ChTP and their modes control systems when having uncertainties of physical mathematical, technological and economical initial data for designing is formulated.

Depending on changes in the uncertainties on the stages of designing and application of ChTP one- and two-step tasks of stochastic optimization with “rigid” and “soft” (probable) limitations are formulated. Methods and algorithms of solving one- and two-step tasks of stochastic optimization as well as tasks of optimum control for continuous and periodical ChTP occurring at integrated designing are considered.

Key words and phrases:complex tense condition; fluidity flow criterion; kinetic equation; thermoactive process.
Abstract:Flow criterion of solid materials under complex tense condition is offered. The criterion is similar to known criteria of strength of materials, since in axes of main tensions it is the equation of second order of surface. The difference of suggested criterion is that constants are expressed not through the limited tensions but deformation characteristics and physical non-linearity of material is taken into account. Besides, application of the criterion together with the kinetic equation of thermoactive process, on the basis of which it is obtained, enables to take into account time and temperature factor when evaluating limited flow condition.

Key words and phrases: andalusian dialect; Spanish literature; speech characteristics of characters; stylistic
device; typifying of characters; phonetic characteristics of dialect.
Abstract: The concept of stylization is considered and the peculiarities of its application as a stylistic device are determined in the paper. The cases of dialect speech stylization (specifically Andalusian dialect of the Spanish language) are examined on the example of modern works of Spanish fiction. It is concluded that mostly phonetic characteristics of the dialect are subject to stylization and the authors tend to create common collective Andalusian dialect out of great variety of Andalusian local speech variants. Quite often they combine and mix together the characteristic features of speech peculiar to different regions of Andalusia and stylize only the most outstanding characteristics of the dialect. As a stylistic device, stylization is used to create speech characteristics of literary characters, particularly, to typify and relate them to a certain geographical area and social sphere. p>
