Surovtsev I. Methods and tools of information technology for determining the concentration of chemical elements in the environment

The dissertation is devoted to solving the problem of the development of effective information technology for determining the concentration of toxic elements. New methods and tool means recovery of the desired signal from noisy data are developed on the basis of theoretical and experimental studies. For the class of monotonically increasing signals that represent the integral sum of multicomponent measurement processes, it is proposed to use the transformation of coordinate system. The transformation consists of filtration, formation and differentiation of the inverse desired signal. The obtained signal of intensity is analyzed as a sum of separate components. The new modeling method, which enables to build a general model of the intensity signal to refine parameters models the base curve and the separate components, is developed. For a substantial increase the sensitivity of the measurement are developed new methods of electrochemical analysis. The developed methods and tool means for digital signal processing are used in new applied information technology of assessment of ecological state of the environment and the earth's atmosphere as well as during the analysis of dynamic physical processes in different areas.
