In the presence of liquid lubricant particles precipitate from wear products or additives, as well as from the wall of the adsorption and chemisorption on metal surfaces contacting bearing surfaces separation occurs at the layers of lubricants with different viscosity properties. For viscous incompressible stratified lubricant in the gap thrust and radial bearings seen in the works.

Considered routing problem in information network in which there are arcs that does not affect the signal quality - neutral and reduce the signal quality - regressive, as well as vertices which improves signal quality - active, and vertices does not affect the signal quality - neutral. The problem reduces to finding the shortest path on the set of paths satisfying the additional restriction - on any segment of the path enclosed between two consecutive active vertices contains no more than a predetermined number of regressive arcs (the same applies to the segment from the beginning of the path to the first active vertex and from the last active vertex to the end of the path, as well as to the ways without active vertices). For such graphs described construction of the reamer - auxiliary graph that allows to find the solution of the problem with restrictions on the original graph as the solution of the corresponding problem without restrictions on the reamer.

The article discusses the relevance of the compact, mobile radio modem sup-ports modern interface USB. The result is the development of a half-duplex tran-sceiver is a device that works with a frequency manipulated signal in a license-free frequency band. The radio modem is equipped with interface USB, through which data is exchanged, as well as its food, as antennas used inefficient quarter-vibrators. Increase in radio range is possible by the use of antennas with high directive gain. Experimental studies of two designed devices were carried out in an urban setting. Their aim was to establish the maximum sustainable radio range (with line of sight) at different data rates as error correction at the reception, and without. Experimenter, away from the transmitting radio modem, monitored the received data. The use of error-correcting coding is most effective at high data rates (up to 3 dB) than at low (1-2 dB). Increase in radio range is possible by reducing the transmission speed - this is due to the dependence of the receiver sensitivity of the speed manipulation. It should also be noted that the decrease in device size is possible by structural modification.
