In modern conditions, internal combustion engines (ice) are the most popular power plant for a number of transport vehicles: cars, tractors, locomotives, river and sea transport vessels. Strict requirements of modern Euro-standards to the degree of "smokiness" of exhaust gases of diesel internal combustion engines and their toxicity contribute to the emergence of a dead end situation. It is almost impossible, using obvious technical solutions, to comply with the requirements of Euro-5 and Euro-6 standards while maintaining the acceptable growth in economic costs, internal combustion engines (ice) emit a significant amount of exhaust gases into the atmosphere, which is an environmental threat. The article considers the method of SHS technology and its advantages.

The article deals with the power supply of the microcontroller core, which allows you to adjust the voltage to ensure the necessary balance between performance and power consumption of the system. When using this source, the core power supply voltage depends on the fill factor of the pulse-width modulated generator. These expressions allow you to adapt the proposed source for a microcontroller with an arbitrary power supply voltage.

The problem of major repairs on the factory highway in Samara still remains unresolved, although the issue has been acute for many years. During this time, as statistics show, there were a lot of accidents and damage to vehicles. A heavy load on the roadbed leads to rapid wear of the asphalt surface, as a result, almost every year the Factory highway needs repairs. The load on the highway will increase even more when the section of road connecting the new Kirovsky bridge with the Zavodsky highway is built. The automobile road in Samara along the ZAVODSKOE highway needs major repairs for several years, but the work does not begin, and every spring its condition worsens more and more. The issue remains relevant today.

The paper discusses modern approaches to the mass valuation of real estate, automated systems for typical buildings assessment, and also provides the development of a method for the continuous assessment of real estate objects, which makes it possible to effectively evaluate groups of real estate objects and infrastructure. This research is aimed at studying the economic component of this process - modeling of a system for assessing the market valuation of real estate in typal development objects. The purpose of the study is to develop a system of continuous assessment (mass valuation) of real estate, taking into account the current methodological support of the process of assessing the market value of real estate, and should contribute to the improvement of the comparative approach to valuation in the framework of the practical activities of appraisers, as well as for state regulation of the real estate market.

The article deals with obtaining RDF fuel based on solid municipal waste. The expediency of using this type of fuel in the cement industry is justified, since its combustion in cement furnaces has less impact on the environment due to the high temperature level of the process. The composition of RDF fuel by elements is analyzed. Due to the fact that this fuel from different sources has a difference in the heat of combustion of two times or more, the heat of combustion of RDF fuel for the middle zone of Russia was experimentally determined and its compliance with GOST R 55127-2012.
