Constructive Modeling of Lightning Activity in Thunderstorm Front
(Institute of Electrical and Electronics Engineers (IEEE), 2019) Shynkarenko, Viktor I.; Lytvynenko, Kostiantyn; Chyhir, Robert; Sansiieva, Iryna
ENG: Using the tools of constructive-synthesizing modeling, constructors of fractal time series which determine the location, magnitude and rate of damping of lighting discharges are developed. Model video images of lightning in the thunderstorm front are formed according to constructors' implementation. The adequacy of the model is verified by comparison of the model video image with the same produced by NASA satellite.
Constructive-Synthesizing Modelling of Multifractals Based on Multiconstructors
(CEUR-WS Team, Aachen, Germany, 2024) Shynkarenko, Viktor I.; Chyhir, Robert
ENG: The concept of constructive-synthesising modelling is presented. The basic principles are determined. The classification of constructors by the purpose of constructing and external relations is presented. The types of constructors are defined: generating, transforming, analysing, optimising/adapting, algorithmic; autonomous, parametric, interactive, multiconstructors. Achievements in the application of the constructive-synthesising approach to solving a variety of problems are presented. The instrumental software "Constructor 1.1" has been developed. Simultaneously with the demonstration of the capabilities of the developed software environment, the formation of flat geometric multifractals is demonstrated. The formation of a multifractal is performed by realization a multiconstructor, which consists of a number of autonomous generating, parametric transforming and algorithmic constructors. The features of the deployment of transformations in the formation of constructors are shown: specialization, interpretation and concretization. The specialization of constructors determines the subject area of construction, necessary data and operations. To ensure the functioning of the constructive processes, all constructor operations must be interpreted by the corresponding procedures of the algorithmic constructor. The combination of the constructor (model of data and possible operations) with the algorithmic constructor (model of the executor) forms a constructive system capable of autonomous constructor by an internal executor. Substitution rules and initial conditions are setting in concretization. The developed software provides a certain flexibility in terms of possible modifications and the formation of new constructors and processes. This toolkit can be used as a basis for modelling various constructions and construction processes, especially in the tasks of their optimisation and structural adaptation.
