Purpose. The goal of this work was the development and research of a method of automatically constructing a digital model of the micro surface of an object from SEM stereo pair of digital images taking into account the specifics of the survey SEM and evaluating the accuracy of digital modeling. Methods. The developed method consists, firstly, in generating a dense set of input points in the left SEM image of a stereo pair in regions with local features and using an iterative process in accordance with the levels of the image pyramid.

The quality of service models of telecommunication networks was considered. The features of providing of quality of service in the telephone and computer networks was explored. On the basis of this research it sets, that the metropolitan telephone networks are characterized by a higher accuracy, dependability and security by comparison to the computer local area networks. Substantial advantage of computer local area networks above the metropolitan telephone networks is providing a higher speed of the user information transfer, although defect there is an instability of this speed.
