Abstract: Transfer functions and equivalent transformed structures of observed-based linear time-invariant control systems with the deterministic unmeasured disturbance have been found. They allow simplifying the analysis of these systems. 2011-01-01T00:00:00Z http://ea.donntu.ru/handle/123456789/11108 Title: DEVELOPMENT OF METHODS AND FACILITIES FOR INCREASING THE METROLOGICAL RELIABILITY OF OPTICAL-ABSORPTION GAS CONCENTRATION METER Authors: Vovna, А.; Zori, А.; Khlamov, M. Abstract: The paper presents a method that increases the metrological reliability of optical-absorption gas concentration meter in dusty condition with required response speed and metrological performance during a long continuous running period. 2011-01-01T00:00:00Z http://ea.donntu.ru/handle/123456789/11107 Title: PROBLEM OF RESOURCE SAVING WHEN ESTIMATING A LEVEL OF CORROSION RISK OF PRODUCTION FACILITIES Authors: Vysotsky, Y.; Korolov, V. 2011-01-01T00:00:00Z http://ea.donntu.ru/handle/123456789/11106 Title: THE INFLUENCE OF COAL MINING LEVEL ON THE DISCHARGE OF EXPLOSIVE GASES TO THE BREAKAGE HEADING Authors: Kostenko, V.; Bokiy, A.; Shevchenko, Ye. Abstract: The paper describes the non-linear nature of methane emission into the breakage heading under the influence of geomechanical and gas-dynamic factors. A promising way of reducing the emission of explosive gases by means of intensifying the extraction above a certain critical level and by means of controlling methane emission from broken coal is offered. That will lead to the decrease of methane emission into breakage headings and atmosphere. 2011-01-01T00:00:00Z
