The problem of indexing of the array of the information demands much on productivity of the information retrieval system. Thus application of a neural network allows to parallelize a problem, that is allow to carry out resource-intensive operations of exact ranging for the documents having chance to appear on enough high places in delivery by results of more rough estimate of their relevance.
In this article, a possibility of a heat supply of housing and communal services with use of thermal pumps is considered. The area, in which thermal pump is the most expedient way to use for heat supply systems is shown
In the article, modular facings of block type, which provide raised reliability to channels of irrigating sys-tems, are offered
In the article trays, channels and pipelines from the traditional and new materials, providing raised opera-tional reliability of a water-spending network of irri-gating systems are offered
The grounds of modeling of filling pile static resistance have been offered so as the results of its realization at the laboratory models. The laboratory testing data are compared with the data of field testing of natural piles. The experimental and the model calculated values of bearing capacity shows the correlation coef-ficient 0,692. The laboratory tests confirm the exis-tence of the local maximum of the settlement “accele-ration”. The point of maximum proposed separates two stages of bearing capacity increment process: the stage of lateral surface mainly resistance and the stage of pile bottom mainly resistance
The article is devoted to the researching of complete observability of time-varying perturbed differential-algebraic system. The method of cascade splitting of the original space to the subspace is used. The formula for finding the state vector is derived. The relations between input and output functions are obtained
Chisel, theoretical principles, new tools, calculation of energy parameters of mechanized processes of tillage are presented in this article
The article is devoted to the plant of alternating illumination for crop growing in the protected soil. The unit forms light conditions by the moving illuminators and by proper gradient angle of the working surface. Characteristic of the unit allows us to produce efficient space and surface distribution of the optical radiation. It let us reduce energy intensity of the hothouse crops growing, increase uniformity coefficient of irradiation, improve the quality of agricultural products
The questions of development and use of intellectual systems for traffic control of public transport are considered in the article. The architecture of intellectual management system and its algorithmic support is also described
The mathematical model of working unit co-operation of plant lifter with soil and roots of plants for optimization of plant lifter’s different parameters is developed
