Mathematical Modeling of Systemic Colorometric Parameters Unmasking Wild Waterfowl

The research presents results of modeling of systemic colorometric parameters, unmasking wild waterfowl.The problem of unmasking wild waterfowl is acquiring practical relevance in connection with problems of biosafety. Such problems are associated with hotbeds and ways of spreading of avian influenza and a number of other dangerous infections and infestations. Moreover, the study of regularities of formation of animals' protective coloration is of interest in terms of a number of fundamental problems of biology and ecology.As a result of conducted research with the use of a new class of mathematical models (DMDS), the authors offered a formalized description of systemic aspects that distinguish between protective coloration of mallard ducks and colorometric parameters of plant communities. The idealized trajectory of the system, reflecting dynamics of colorometric parameters of phytocenosis in the habitat of mallard duck, was constructed. The idealized pseudo-trajectory of the system, reflecting a set of combinations of colorometric parameters of protective coloration of mallard duck, was constructed. The kind of systemic colorometric parameter, which allows unmasking the mallard duck against the background of phytocenosis, was determined. Root mean square deviation of values of difference of colorometric parameters of digital photography of the researched area was selected as the systemic colorometric parameter. The systemic colorometric parameter reflects variability of ratios of difference of values of colorometric parameters in the sample of microsegments, into which the segments of the image of the studied area are divided. The obtained results offer new approaches to development of remote methods of studying living conditions and migration routes of wild waterfowl

Mathematical Modeling of the Colorimetric Parameters for Remote Control Over the State of Natural Bioplato

An approach to the remote determination of the character of bioproduction processes in aquatic phytocenoses is proposed. The investigated plant communities can be used as natural bioplato for the elimination of biosafety threats to water consumption. The relevance of these studies is determined by the increased need for expanding the arsenal of methods for remote diagnosis of the states of natural systems that are important for biosafety provision. In particular – to ensure biosafety when using natural feed resources by waterfowls, which are a potential reservoir of bird flu.The similarity in the dynamics of the colorimetric parameters of phytocenoses and the Margalef's succession model makes it possible to implement a new approach to the generation of productive working hypotheses for the development of remote methods for determining the state of bioproduction processes in natural bioplato. The proposed approach is based on the use of the class of mathematical models, which is called the discrete models of dynamic systems.Based on the structure of the correlations between the colorimetric components of space photographs of the plavni in the mouth of the river Danube, a description of the structure of the intercomponent and intracomponent relations of the massifs of semi-submerged higher aquatic plants has been obtained. The resulting structure of intercomponent relations allowed us to construct idealized trajectories reflecting the dynamic changes of the system. A unique constant inverse relationship between the parameter reflecting the amount of green chlorophyll pigment affecting the level of photosynthetic production and the parameter reflecting the amount of orange-red pigments in each of the possible matrices of the ratios of colorimetric parameters has been revealed. As a result of analysis of the dynamic aspects of the RGB model, the structure of the system color parameter is shown, which is the mean square deviation of the spread in the degree of alignment of parameter values reflecting the amount of green and orange-red pigments.As a result of analysis of the systemic colorimetric parameter of photographs of the section of the Danube plavni during various periods of the vegetative season, it is shown that it is advisable to use it as a marker of the risk of secondary water pollution, which can be used for remote determination of the state of bioproduction processes in natural bioplato
