There is a need to universalize the diagnostic processes of the operability of various radio technical devices and communication systems (RDCS). However, the presence of a wide range of ISSS requires different, sometimes extremely specific, approaches to their diagnosis. In addition, there is no universal method for storing and processing information containing signs of certain malfunctions, deviations in the quality indicators of the RDCS operation, the reasons for their occurrence and how to eliminate them. It is proposed to solve this problem by using an automated analysis of the quality indicators of the work of the ISSS in the semantic expert system. It will allow you to flexibly associate any indicator of the quality of the RDCS with the cause that influenced it, as well as to link the latter with the method or methods of eliminating the cause, which will provide the proposed algorithmic and software with the opportunity to accumulate knowledge in the field of performance analysis and act as an expert in the process of diagnosing the RDCS.

Ground handling is part of the work process of any onboard complex. The article presents a model of the process of such service, based on the queuing theory methods. The model based on the assumption that random values describing these processes may have arbitrary distributions, which in turn affects the quality of board service. Differences in the values of quality indicators can reach in the case of different distribution laws, they can differ by an order of magnitude, which can be of significant importance when deciding on the deployment of the next point of on-board service. The fundamental importance has that are investigated not the average values of service quality indicators, but their maximum values, which are guaranteed for a predetermined proportion of the entire flow of boards arriving for service.

A well-known complex of methods for converting signals into binary digital form is shown, potential theoretically achievable boundaries of such conversions are determined. Values are calculated that indicate the value of the code distance between the original values and those obtained after transformation. Euclidean space metric. A correspondence is established between these messages and binary code combinations in the Hamming space. It is proved that in some cases the values that determine the distance between messages and the metric are quite general and should be clarified for specific situations. Distortion minimization is suitable for cases where the minimum code distances of the primary metric space are related to the minimum code distances of the secondary metric space. And also in the article the admissible limits of such minimization are found.

Few-mode, multicore, and few-mode multicore optical fibers are considered. The concept of multichannel optical fibers (MChF) is introduced. The criterion of fiber channel order is formulated and the spatial-channel classification of optical fibers is being constructed. Analytical expressions for calculating the transfer and spatial parameters of MChF are presented. For variations in the spatial and spectral resource of quartz MChF, the values of capacity and spatial-rate efficiency are determined.

The technique of calculation of vehicle weight with the use of discrete piezoelectric sensor for automatic weight and dimensional control systems of vehicles, allowing to make calculations with the least errors in comparison with the existing monocrystal analogues, is presented. Improving the accuracy of measurements is necessary to improve the quality of the procedure for assessing the physical characteristics of the vehicle at the points of automatic weight and dimensional control.

The issue of using neural networks to construct and correct the transport object trajectory is considered in this article. The control system, which includes the analysis of general unchangeable information received from global sensors, is considered. The decision on the need to change the trajectory is made depending on the data received from sensors located directly on the object. A method is proposed for correcting the autonomous object route depending on the occurrence of stationary obstacles during movement. A neural network is defined that minimizes the functional characterizing the cost of movement and its safety, taking into account the rebuilding.

Zero-collision program in traffic has become an important target for many metropolises and regions. Among the wide range of traffic accidents reasons the human factor plays one of the most significant roles. Monitoring, analysis and control of driver's behavior is the way to drastically improve the traffic safety. The driver's biological responses and parameters control combined with the modern driving assistance technologies provides a great opportunity to decrease human error. This paper proposes a system, which is based on EEG (electroencephalogram) recording and predicts emotion fluctuations which can cause the dramatic decision making.
