The time series analysis has played an increasingly important role in weather and climate studies. The success of these studies depends crucially on the knowledge of the quality of climate data such as, for instance, air ...

Topology is the branch of mathematics that studies how objects relate to one another for their qualitative structural properties, such as connectivity and shape. In this paper, we present an approach for data clustering ...

In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using ...

The work analyzed ARIMA models for forecasting day-ahead price clearing markets. The models were based on time series analysis and provide reliable and accurate market price predictions. The objective was to verify the ...

Monthly prevalence of canine rabies in Argentina (1971-1993), Bolivia (1987-1993) and Paraguay (1976-1993) were analyzed to identify seasonal cycles of the disease. Moreover, data to forecast the evolution of rabies were ...

The Spanish Antarctic Station Juan Carlos I has been registering surface air temperatures with the frequency of one reading per ten minutes since the austral summer 1987-88. Although this data set contains valuable information ...
