W pracy rozważono statystyczny opis przepływów turbulentnych przy wykorzystaniu metody funkcji gęstości rozkładu prawdopodobieństwa charakterystyk przepływu. W szczególności otrzymano równanie ewolucyjne dla jednopunktowej funkcji gęstości prawdopodobieństwa pulsacji koncentracji dyfundującej substancji w zadanym polu prędkości cieczy. Rozważono bliżej przypadek statystycznie stacjonarnego i horyzontalnie...
The paper concerns nonparametric estimation of probability density functions (PDF). We demonstrate how one can use PDFs for easy and smart analysis of opinion polls data. Authors use PGSS dataset (Polish General Opinion Poll) made freely available in ADS [11] library. PGSS contains data collected during a large number of opinion polls carried out between 1992 and 2008. It contains answers for 1640...
