Abstract. Coccolithophores play a key role in the marine carbon cycle and ecosystem. The carbonate shells produced by coccolithophore, named as coccolith, could be well preserved sediment for millions of years become an excellent archive paleoclimate studies. micro-filtering sinking–decanting methods have been successfully designed coccolith separation promoted development geochemistry studies ...

This paper used the gradient blind signal separation algorithm to carry out the electrical power system harmonic signal analysis through the simulation experiment. The experiment result proved that the electrical power system harmonic signal separation based on the gradient algorithm is accurate. Through comparing the separation performance by using the different step size, the adaptive changin...
