Abstract It is designed and applied principle new high-intensity ultrasound unit of new stage based on radial transducer. Designers of that unit are Ltd “Aphalina” (Moscow) and STU MADI. Ultrasonic cleaning node consists of digital ultrasonic generator, piezoelectric transducer and radial tool with automatic agreement resonance frequency. The unit provides gentle cleaning of injectors of any constructions.
Abstract The article results of the spent researches of work of several schemes of divided overpass superstructures with junctions and branches, typical for multi-level urban traffic interchanges under the loadings accepted in norms of Vietnam are presented. The attention to distribution of efforts in a branching or branch zone flying structures is paid and conclusions on features of work of divided bearing bridge designs are drawn.
Keywords finite element method, via duct, span of a bridge.
Abstract Today the structure of demand in the Russian wholesale electric power and capacity market sees oligopsony, which is confirmed by the result of estimating the level of buyers’ market concentration with Herfindahl-Hirschman Index (HHI). These changes created new buyers’ strategies on the wholesale electricity market. This article presented the principles a buyer uses to choose competitive strategies (including manipulation ones), formalizes a number of mathematical models taking into consideration the specific features of the electricity market, proposes the methods to solve them.
Keywords competition, electric-power industry, the electric power and capacity market, Herfindahl-Hirschman Index (HHI), oligopsony, strategies, models, state regulation.
Abstract In clause necessity of planning proves, and economic-mathematical models and an example of optimization reproduction structure of capital investments in development of a regional network of highways are considered.
Keywords reproduction structure, planning of capital investments, methods of optimization, road constructions.
Abstract This article was created in order to provide a detailed and overwhelming overview of nature and types of interest rate risk. The goal of this publication is to present the information required to form a clear understanding of interest rate risk as a complex economic entity. Within the text a comparative analysis of existing interest rate risk definitions is performed and the authors definition is provided. In the final part of the article the nature of interest rate risk is described through reference to foreign exchange risk.
Keywords interest rate risk, interest rate risk definition, types of interest rate risk, nature of interest rate risk, discounting.
Abstract Street - high system video monitoring represents visual fastening of a road infrastructure and titles of roads in the course of movement with the subsequent engineering processing. Road laboratories for video monitoring should be equipped by a complex consisting of system of shooting of video images, high-precision measuring systems and systems of computer data processing.
Keywords video monitoring, a hardware-software complex, mobile road laboratory, road object, bank of the road data.
Abstract The article presents analysis of the most popular training algorithms for multilayer perceptron in the framework of pavement distress segmentation. The study shows that Levenberg-Marquadt Algorithm is the most effective. Modification of this algorithm could be used for the pavement cracking recogntion task.
Abstract In article results of the researches connected with perfection of logistical technologies for guarantee systems of the international road transportations (IRT) within the limits of preventive actions, the risks directed on decrease in IRT are stated. The basic conditions of activity are considered at IRT and possibilities of use of organizational, methodical and economic potential noncommercial the organizations based on membership for support of activity in the field of IRT.
