La Geometría Fractal es una nueva manera de ver la matemática en la naturaleza. En la actualidad tiene un notable aumento en cuanto a su desarrollo teórico y aplicado, mostrando ser idónea para describir los procesos naturales. Por tanto, en el presente trabajo se presenta como una herramienta para agilizar el proceso de actualización cartográfica aplicada a objetos naturales y antrópicos. A partir del algoritmo Box-Counting, se determina la dimensión fractal Box-Counting de los objetos naturales para utilizarla como un índice espacial de comparación que describe la capacidad que tiene un objeto de variar en el espacio a través del tiempo, y poder determinar así la necesidad de llevar a cabo la actualización cartográfica o no. Se verifica mediante un ejemplo real que el resultado obtenido es significativo tras la ocurrencia de eventos extremos y se infiere su utilidad para realizar una actualización cartográfica parcial de la zona afectada, lo cual reduce costos en el proceso cartográfico
Colombia is an exporting country of quality coffee in the world; divergent factors in the short and long term, such as inclement weather, geographic changes, and socio-political development, are some of the factors that influence the price of this product. Knowing the future behavior of this phenomenon is one of the most important studies for economists, academics, coffee growers, entrepreneurs, and exporters. Brownian motion, a physical phenomenon that describes the irregular movement of some particles suspended in a fluid, was described by the probability of finding a particle in a position at a specific time. Fractional Brownian motion describes the random fluctuation of a stochastic process continuous in time and is characterized by the Hurst coefficient to observe persistence and volatility in a time series. The percentage of volatility that changes in the price of coffee present allows generating strategies to maintain the quality of the product and, therefore, its positioning in the market. In this work it was found that the series of data on coffee prices is persistent and that its volatility is 43.77%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
