Popov A. Mathematical and computer modeling of the technogenic loadings on the city atmosphere from stationary dot contamination sources

The research object is the process of the pollutants in the surface layer of the atmosphere. The aim of the thesis is to build mathematical models of processes of distribution, taking into account the statistical nature of climatic factors in the studied region. Building on the basis of models the information and computer modeling system for forecasting of risk and technogenic loads. Methods of mathematical and computer simulation, analytical geometry, the principles of object-oriented programming are used. The novelty of scientific results is the following: 1. Based on the statistical approach developed by the IAEA model modifications and K-Roberts model, adapted to determine the spatial distribution of technogenic loads on the atmosphere from stationary point sources of emissions, taking into account the dynamics metrological factors over a long period of time. 2. A method of modeling results visualization is proposed for technogenic loads on the atmosphere from stationary point sources of pollution emissions in the form of environmental maps. 3. The structure and algorithmic organization of autonomous Modeling Systems for the tasks of monitoring technogenic loads on the atmosphere of dangerous enterprises are developed. A software design and cartographic display are performed for technogenic loads and risks from exposure to industrial companies. The specialized interface for users in the field of environmental security is constructed. The results of the thesis realized in the Office of Information and Analysis of Emergencies of Ukraine and the All-Ukrainian Scientific Research Institute of Protection from emergency situations of technogenic and natural character.
