The methods for determining the standards for the preventive maintenance system and repair are analyzed, it is found that the current norms are essentially outdated and require revision at the federal level. It is shown that the specifications for maintenance and repair specified by the operating time for modern cars should be revised in favor of standards determined by their condition, which will allow the introduction of individual standards for each car, taking into account the operating conditions and its technical condition.

The method of determining the speed of a bus before its overturning is considered. According to statistical studies, it was found that rollover of buses is a fairly common type of traffic accidents (road accidents). However, in this kind of accident, a large number of casualties and even deaths are recorded. In such cases, the investigator-investigator must identify the culprit in the accident, as a rule, it can be a master for the production of vehicles on the line, if the cause is a bus malfunction. In addition, it can be drivers of other cars or pedestrians. The driver of the bus, who took the wrong actions in the current dangerous situation, can also be guilty. The most common cause of an accident is the driver violating the speed limit. Therefore, the investigator-investigator must determine how fast the bus moved before tipping over. For this, there is a standard method for determining it. Based on the received speed value, it is concluded whether the driver violated or did not violate the established speed regime. However, this technique will give excessive values ​​of speed, for example, if the driver has made a maneuver "rearrangement", known as the elk test. Thus the bus, moving on an arc in the beginning in the right, and then to the left with the resolved speed, has risk to overturn. This is due to the impact of the alternating centrifugal force, as well as the additional forces acting on the bus bodies, due to the compression-expansion of the suspension springs. The article defines the speed of the bus before the overturning, at the time of the maneuver "rearrangement".

The models of resolution of the main types of intrapersonal conflict are given. They are all connected with the choice of the object or action (equal or different valence) of two equiprobable (still attractive). The models were built in the discrete event approximation. It is based on the assumption that the opinion of the subjects about the usefulness of the objects undergoing random fluctuations at each step. Their attraction is the same only average. The second basic hypothesis is that the subject intuitively changes its assessment of the probability of selection after the change of the attractiveness. The transformation probability is modeled using Bayesian theory of decision-making. Numerical experiments showed the viability of such model. It is obtained that in the end, the situation with the choice of is permitted in one direction or another (equiprobable at the level of the final decision). The time resolution is inversely proportional to the width of the fluctuation of attraction. In the work it is also investigated the influence of evaluation by the subject of the significance of the objects. Obtained as a very low evaluation, and Vice versa, too high, hinder the resolution of conflict. The minimum completion time is achieved a little distant relation of the subject to the object (process) conflict. The results are as purely situational, specific significance, and the overall methodological. The presented models allow for an easy generalization to more complex cases involving a variety of factors influence and can serve as a basis for such studies.

The article is devoted to the problem of data protection from interception as a result of the "man in the middle" attacks. The proposed technique for detecting these attacks is based on the analysis of the headers of transit packets passing through the default gateway. Based on the data obtained, a table of correspondence between IP and MAC addresses is constructed, for which software provides up-to-date and reliable information. The addresses of packets passing through the gateway are compared with the records in this table and, in case of a mismatch and impossibility of confirming the correctness of addresses in the headers of the channel and network layers, it is concluded that there is an additional intermediate node in the network that appeared as a result of the default gateway substitution. The article presents approaches to software implementation of this technique, describes the packet analysis algorithm.

The article substantiates the necessity of obtaining the dielectric properties of grain materials for studying the processes of microwave convective heat treatment of grain. The shortcomings of the existing methods for studying dielectric properties in the study of a fluidized bed and suspended layer are described. A laboratory installation and an experiment on the investigation of a suspended grain layer are described. The results of experimental studies on the determination of the dielectric loss factor of wheat subjected to microwave treatment are presented. The results obtained for different material densities correspond to the general dynamics, but differ significantly in level. Thus, for a dense layer, which corresponds to a density of 660 kg / m3 in the humidity range of 11-30%, the dielectric loss coefficient varies in the range 0.18-0.42; for the fluidized bed (440 kg / m3) 0.06-0.15; for the weighed (220 kg / m3) 0,1-0,3.
