Nelinearna dinamička analiza fizičkih procesa u žiivotnoj sredini

Abstract

Ispitivan je spregnut sistem jednačina za prognozu temperature na površini i u dubljem sloju zemljišta. Računati su Ljapunovljevi eksponenti, bifurkacioni dijagram, atraktor i analiziran je domen rešenja. Uvedene su nove informacione mere bazirane na Kolmogorovljevoj kompleksnosti, za kvantifikaciju stepena nasumičnosti u vremenskim serijama,. Nove mere su primenjene na razne serije dobijene merenjem fizičkih faktora životne sredine i pomoću klimatskih modela.

Coupled system of prognostic equations for the ground surface temperature and the deeper layer temperature was examind. Lyapunov exponents, bifurcation diagrams, attractor and the domain of solutions were analyzed. Novel information measures based on Kolmogorov complexity and used for the quantification of randomness in time series, were presented.Novel measures were tested on various time series obtained by measuring physical factors of the environment or as the climate model outputs.
