Through a cultural-historical analysis, the chapter portrays the Opera-Telephone in Munich as a special means of listening and explores its technical, social, economic, and psychological aspects. These aspects strongly reflect the reciprocal relation of technical innovation and listening to music, for example, by emphasizing the meaning of live broadcasting for listening habits and by highlighting the impact of headphone use on aural perception. The latter practice enables the transfer of the multidimensional opera event into a pure listening experience as the visual element is eliminated. The Opera-Telephone also serves to illustrate matters of social status in regard to private and public listening. In this way, opera was incorporated into the marketing of modern technical products.

The article is devoted to the substantiation of the procedure for testing complex technical systems to assess the probability of performing the task, taking into account a priori data obtained from the results of modeling, field tests of components and prototypes, operation of analogues, etc. The conditions for the formation of a combined sample consisting of field experiments and experiments counted on the results of modeling are justified. Data uniformity is checked using the Student's criterion. The minimum volume of full-scale tests is determined by the requirement of equality of the amount of Fischer information about the estimated parameter obtained during full-scale tests and at the expense of a priori data A strategy for conducting field experiments is proposed, in which the required quality of evaluating the probability of completing the task is achieved with the minimum possible number of field experiments. At the first stage, a series of experiments with a volume equal to half of the required sample size is performed. At the second stage, the experiments are conducted sequentially with an assessment after each experiment of the requirements for the amount of information about the evaluated parameter and for the uniformity of data. Experiments are terminated when the specified requirements are met, and then a combined sample is formed, which is used to evaluate the probability of the system performing the task. A model example is considered. The estimation of the gain in the number of experiments performed at different probability values was carried out.

<p>Previous studies examined additional willingness to pay for socially responsible primary goods. However, technical products have not been considered. Therefore, the purpose of this study is to estimate additional willingness to pay for socially responsible technical products. Within an overview of given methods for measuring willingness to pay, the discrete choice analysis was applied to this study. As technical products, computer mice were chosen exemplary, since there is a partially fair mouse available. It was found that two of three fair labeled mice have a negative willingness to pay. Only consumers of the fair produced and labeled mouse has a positive willingness to pay. The consumers pay perhaps more attention to the aspect of social responsibility, if presented brands are comparatively unknown. In this connection, consumers allocate a higher value to social responsibility.</p>

Up-to-date directions in the development of modern industry increase the requirements for the quality of technical products. The design and manufacture of competitive process equipment require accuracy, productivity, and efficiency. Therefore, in this article, a new mechatronic system has been designed and developed to help porous, permeable materials with predicted porosity have been produced. The research aims to develop a mechatronic system for technology optimization in manufacturing permeable porous materials with controlled properties. As a result, the method of computer modeling of porous, permeable materials was developed. It allows us to consider the peculiarities of porosity distribution and radial velocity in radial isostatic compression. Additionally, a new mechatronic system for producing permeable materials allows us to determine the porosity distribution and particular characteristics of permeable powder material. The proposed approach allows us to evaluate the impact of technological modes on the main operational characteristics.

The article reports on the new technology and equipment of vertical‑stack molding (VSM), created by OJSC “BELNIILIT” for the manufacture of vertical‑stack molds. The development is intended for the production of molds and cast blanks of oil, which are later used for the manufacture of piston rings of internal combustion engines.The difference between the above‑mentioned technology and traditional methods of VSM is the use of models without drafts. The development is export‑oriented and has a great economic effect for ring manufacturers due to the absence of drafts on castings, since part of the mechanical operations for their processing is excluded, the metal consumption of blanks is reduced, the production spaces required in this regard are reduced, the necessary labor supply is reduced, etc.OJSC “BELNIILIT” has successfully carried out experimental design and technological work on the new scientific and technical products creation, which are of great interest to the world manufacturers of piston rings. An industrial sample of a molding machine and a mold manipulator were manufactured.
