All-Russian and regional exhibition architecture in the second half of the 19th century through the early 20th century had varied distinct differences in style and design. Temporality of exhibition architecture in those days contributed to a variety of experiments made for pavilions in the context of styles and structures. There was a high demand for the Russian style to be applied for pavilions both in Russia and abroad. First search and application experience in respect to the modern art principles are connected with exhibition architecture. These experiments in the national architecture and art are of a high interest. Neo-classicism was applied in exhibition architecture in the early 20th century to a large extent. The exhibitions of the early 20th century appeared to be special ‘style workshops’. Organizers of certain exhibitions tried to keep uniformity of style of basic constructions. The major merit of exhibition architecture is that it contributed to the transition from eclecticism to a new style on the cusp of the 19th and beginning of the 20th centuries.

Transition to a new approach related to use of facades and roofs entirely made of glass in building construction called for an additional analysis to evaluate an issue of how to ensure an interior climate. In the article have been investigated the factors, which make people feel uncomfortable in the pavilions with large glazing areas: cold air flow near glazing area, which occurs on the cold surfaces of the windows, going down and along the floor, radiation heat exchange between human beings and building envelopes, condensation on internal glazing surfaces.

At present time translucent structures have appeared to be the most crucial issues regarding building envelopes in relation to high heat losses in the cold periods of the year. Development of the methods to improve thermal properties of translucent structures is considered to be an up-to-date issue. Heat losses of exhibition halls with varied dimensions ratio and energy consumption of heating systems have been determined for the case of the city of Saint-Petersburg (Russia)

The paper describes a diagnostic system for electromechanical equipment with a decision-making block based on a neural network. An asynchronous gear drive was used as a control object. Decision making was carried out on the basis of a comprehensive analysis of vibration data (from the gear drive) and the current consumption of the induction motor. Vibration velocity, vibration acceleration and current in the phases of the stator winding of the drive electric motor are distinguished as diagnostic signs. The work shows the possibility of increasing the efficiency of diagnostics of electromechanical equipment by using complex analysis with the use of an intelligent decision-making unit. Analysis of the results of the neural network operation with the received vibration and current data showed that with a smaller number of iterations (training time) (by 40 %), 97.9 % of correct answers and a lower error value (by 12 %) were obtained.

Introduction: By determining the importance of industrial architecture as an object of cultural value, it is possible to identify the new principles for preserving the identity of a historical location. Purpose of the study: We aim to research different periods in the formation of the architectural and spatial layout of industrial buildings and structures; to determine which principles are applied when the buildings and structures are adapted for reuse. Methods: In this article, we use a synergistic approach to studying the specifics of the historical and cultural development of industrial architecture. Results and discussion: After analyzing the target of our study as a self-organizing system, as well as taking a look at its relationship with various structures, depending on the nonlinearity of the ongoing processes, we came to the conclusion that the emergence of different stylistic trends in industrial architecture can be viewed through the lens of significant historical periods, or bifurcations, which were the result of human activity in the past and would influence the functional development of the resulting space in the future. This approach reflects sociocultural needs and unlocks the potential for reusing historically significant industrial sites in various ways.
