An important factor of development of modern telecommunication networks is to assure the efficiency of their work and proper parameters of quality of provided services. Therefore, the development and implementation of effective methods and facilities of connection quality assurance is the topical issue. The article deals with the analysis of problems of quality assurance in telecommunication networks, and some modern methods for solving the set task are considered on the basis of integrated IntServ and differentiated DiffServ service models. © 2015 Kharkiv National University of Radioelectronics.

The article gives a classification of isothermal rolling equipment depending on the heat transfer coefficient, which evaluates the total heat-mass transfer through car body enclosure. This allows forming of the modern isothermal cars fleet in current transfer conditions of perishable grocery, artificial packaged and palletized freights, which require a protection from atmosphere precipitation and temperature differential. © Metallurgical and Mining Industry, 2015.

We examine the methods of laser beam classification and their uses. We discuss the necessity of noise filters using adaptive methods in beam reflection, such as parallel-hierarchical networks. A demonstration of this network is shown on a programmable logic device. © 2014 Society of Photo-Optical Instrumentation Engineers (SPIE).
