A formalized algorithm is presented and a calculation of communication breakdown in atmospheric optical transmission systems is made depending on the intensity of precipitation based on published statistically processed experimental data on the quantitative characteristics of the distribution of raindrops by size. Based on the meteorological data received from the weather stations of the Karshi airport, statistics on the minimum visibility range have been compiled. Based on these data, the integral distribution functions of the minimum visibility range and kilometric attenuation necessary to take into account the climatic features of a given geographic area, when designing open optical transmission systems, were calculated.

The paper is devoted to the need for state-of-the-art trend in distributed computing - Fog computing as well as its distinctions in terms of an architecture and technical aspects with cloud computing followed by prerequisites to Fog platform so as to be able to deal with real-time Big Data obtained from evolving Internet of Things/Everything devices and wireless sensor networks. Fog computing is arguably either a virtualized platform or real equipment typically located between end user devices and the cloud data centres hosted within the Internet. As compared to Cloud computing, it has a number of distinctions such as low latency, low jitter, the location of fog nodes at the edge of the local network, one-hop distance between the client and the server, a tremendous number of server nodes distributed geographically, the support of mobility along with real-time interactions, etc.

Finding and tracking moving objects in a video stream is an important task for a different class of tasks that need to allocate moving objects on a complex background. Image segmentation based on mask selection is considered for solving this class of problems of rotation and scale of the image has little effect on the amount of calculations. In addition, the contours completely determine the shape of the image, are slightly dependent on color and brightness and contain the necessary information for further classification of the object. This approach makes it possible not to consider the internal points of the image and thereby significantly reduce the amount of information processed by moving from the analysis of the function of two variables to the function of one variable. The consequence of this is the possibility of ensuring the operation of the processing system on a time scale closer to real. Despite the GIS (Geographic Information Systems/Geospatial Information Systems) have been provided with several applications to manage the two-dimensional geometric information and arrange the topological relations among different spatial primitives, most of these systems have limited capabilities to manage the three-dimensional space. Other tools, such as CAD systems, have already achieved a full capability of representing 3D data.

寻找和跟踪视频流中的运动物体对于需要在复杂背景下分配运动物体的不同类型的任务来说是一项重要的任务。为了解决这类问题，考虑了基于掩模选择的图像分割，图像的旋转和缩放对计算量的影响很小。此外，轮廓完全决定了图像的形状，稍微依赖于颜色和亮度，并包含了进一步分类物体所需的信息。这种方法可以不考虑图像的内部点，从而通过从两个变量的函数分析转向一个变量的函数分析，大大减少了处理的信息量。这样做的结果是有可能确保处理系统在更接近实际的时间尺度上运行。尽管GIS (Geographic Information Systems/Geospatial Information Systems)已经提供了一些用于管理二维几何信息和排列不同空间基元之间拓扑关系的应用程序，但大多数这些系统对三维空间的管理能力有限。其他工具，如CAD系统，已经实现了表示3D数据的完整功能。尽管GIS (Geographic Information Systems/Geospatial Information Systems)已经提供了一些用于管理二维几何信息和排列不同空间基元之间拓扑关系的应用程序，但大多数这些系统对三维空间的管理能力有限。其他工具，如CAD系统，已经实现了表示3D数据的完整功能。尽管GIS (Geographic Information Systems/Geospatial Information Systems)已经提供了一些用于管理二维几何信息和排列不同空间基元之间拓扑关系的应用程序，但大多数这些系统对三维空间的管理能力有限。其他工具，如CAD系统，已经实现了表示3D数据的完整功能。

This study examines the issue of optimization of management models, which mainly focuses on the prediction of economic indicators and management based on neural models. Non-stationary processes, reflecting technological, economic, social, biological, physical phenomena, are characterized by quantitative and qualitative characteristics, which are characterized by abrupt, evolving development and regulation of parameters over time. Modeling of non-stationary processes in the general case can be carried out using traditional mathematical methods, but today a promising area of research is the use of modern methods of intelligent data processing, one of the brightest representatives of which are neural network technologies. Therefore, it is important to improve management models to implement the above tasks.
