The article uses a method of modernizing solutions for constructing vehicle monitoring models made using standard Bragg structures. The applicability of fiber Bragg gratings (FBGs) with structural defects such as phase shifts is carried out. This article proposes a fiber-optic sensor system (FOSS) based on FBG with a phase π-shift, which makes it possible to switch from optoelectronic interrogation methods to radio-photonic ones. The radio-photon approach is presented as an effective method for detecting vehicles in normal traffic. The principle of information signal formation when measuring vehicle parameters. This FOSS allows, on the one hand, to get rid of an expensive optoelectronic interrogator, on the other hand, it requires the construction of neural network models for its work to determine cars of different types and weights.

A comparison of different methods of segmentation of digital images of sputum stained by the method of Ziehl-Nielsen. We considered the following methods: threshold binarization, method binarization Otsu, detectors borders (operators Roberts, Sobel, Prewitt, Robinson and Kenny), detectors of Harris corners and FAST (Features from Accelerated Segment Test) algorithm, artificial neural network and wavelet transform Mexican Hat, as well as the search function of the contours of the OpenCV library. To analyze the quality of the image segmentation and time spent for carrying out segmentation. Concluded that the use of the wavelet transform Mexican Hat has the best quality segmentation with a relatively small time spent.

The article considers the possibility of creating distributed transmission and accounting networks for energy resources. The experience of different countries in creating smart networks was also analyzed and the effectiveness of such systems was evaluated. "Intelligent" systems allow you to distribute energy more efficiently for end users. In addition, "smart" systems allow you to track leaks, accidents, and theft of electricity. The problems associated with the deployment of smart networks are considered. The main features and problems of introduction of accounting systems of housing and communal services in Russia are given. The system of state information system of housing and communal services is considered.
