Create a distributed network for the sale of bus tickets as a way of higher-availability of passenger transport
Automating the process of bus stations in most cases aimed at streamlining the system of accounting reports, as well as reducing unnecessary costs of the enterprise. At the same time, the end user practically does not feel the changes in the process. Improving the use of technology bus stations should be aimed primarily at the consumer la services — passenger. One of the options for improving the systems of automatic control bus stations proposed in the paper.
Keywords: automation of the process, the automated system, we control, passenger transport, transport safety, throughput ability of the bus station ticket offices.

Probability of functioning of a audio informational device, that was randomly selected for subscribers line
Nonvolatile audio information devices are power supplied from stationary power source by means of subscriber line. Their energy effectiveness is double of prototypes because of rational energy use in DC circuit holding. The subscriber line output is limited by the cable length and type. The audio information devices operation probability dependence on subscriber lines length distribution is shown in the work.

The module of amplification and relaying of the optical signals for the free space optics
The deficit of the free space optics (FSO) is the dependence of admissible length of the atmospheric channel from properties of the propagation medium. The module of amplification and relaying of the optical signals is used in order to lower dependence of communication quality FSO from an atmosphere condition. The feasibility of the practical realization of the method suggested has been examined on the numerical example.

Modern approaches to the study of the behavior of a connected stream of particles with motivation
We consider the collective motion of particles. It possesses a certain order or configuration. The behavior of each particle depends on the motion of neighboring particles. For example, if a unilateral movement of particles in a straight line, the leader moves on to some rule. Each of the following particles is driven and moves at a speed that sets the distance to the next particle distance safety (DS). When moving along parallel straight flow characteristics determines the behavior of leaders. Movement of the leaders is dependable.
Keywords: Collective motionof the particles, the study quantitative and qualitative characteristics movement.
