Developing models to analyze time series is a very sophisticated, time-consuming, but interesting experience for researchers. Commodity price component determination challenging due remarkable volatility, uncertainty, and complexity in the futures market. This study aims determine components that drive market of commodity futures. utilized decomposition methods, empirical mode (EMD), variationa...

Decomposition spaces are a class of function constructed out “well-behaved” coverings and partitions unity set. The structure the covering determines properties decomposition space. Besov spaces, shearlet mo

Sedimentary rocks can record signals produced by highly complex processes. These are generated a progressive deposition of sediments which be affected, mainly through the climate system, regular astronomical cycles (i.e. Milankovitch cycles), and irregular oscillations like El Niño-Southern Oscillation. Also, usually biological, chemical and/or physical post-depositional processes, sedimentary ...
