The completed observations have confirmed the expediency of vertical installation of the all-season electro helio water heater’s collector under certain conditions. In summer, Kv is considerably more than unity. In winter and low season, Кv is nearly equal to unity, which is necessary
The article shows the results of experiments to assess the effectiveness of multipoint and polygamous, which form the basis of the proposed mixed-evolutionary method, in comparison with known genetic methods
The article reviews the results of the computational experiment by means of mathematic model of a small bioreactor with the bubble mixing system and catalytic heating. We considered the quantitative relationship between design parameters of a bioreactor and parameters of its effectiveness
The article presents the description of the method and the results of the experimental research of loading of driving mechanism of felling head of a forest machine
In this article we have considered a seismic survey technology to refine the geological structure and the determination of physical and mechanical properties of soils in the operational methods of nondestructive testing and prediction of physical stability of hydraulic structures (dams)
In the article, the review of method of histological structure definition of different wood types is given. The particularity of softwood, hardwood diffuse-porous and ring-porous structure is discussed
A stress-strain state of landslide soil during interaction with piles has been considered. The dependences of the critical landslide pressures from soil non-squeezing condition have been given. It was established, that account of passive reaction of lower slope essentially increases resistance of construction against soil squeezing
In the article questions of optimal control of tempera-ture maintenance in a cattle-breeding complex are considered. Possibility of use of discrete management is shown. The optimum step of digitization is found
The variants of fastening of harvest-transport groups to fields and their influence on the reduction of need in automobiles are observed in this article, on the example of two farms
This article presents the variant of the implementation of a system for heating supplying of buildings for placement of bees based on catalytic devices for burning biogenic fuels, as well as it offers a general idealized model of quantifying the effectiveness of technical-technological system
