The separation of the field produced by different internal sources can be accomplished by means of the so-called spatial spectrum of the geomagnetic field of internal origin. It is shown how such a ra...
Magnetic separation of calcite and aragonite for use in radioactive carbon analysis

Aragonite and calcite often coexist; as such, separating these very similar minerals is an important step in undertaking
research on these two phases individually. One approach to discriminating betw...
On the separation of timescales in spring-block earthquake models
separation of timescales spring-block earthquake models
2009/11/9
One of the most widespread spring-block earthquake models, the Olami-Feder-Christensen model, is investigated without making the assumption that the duration of individual earthquakes is negligible. W...
A propagation-separation approach to estimate the autocorrelation in a time-series

2009/11/2
The paper presents an approach to estimate parameters of a local stationary AR(1) time series model by maximization of a local likelihood function. The method is based on a propagation-separation proc...
