What makes a steady flow to favour kinematic magnetic field generation: A statistical analysis
Francisco Stefano de Almeida, Roman Chertovskih, Sílvio Gama +1
To advance our understanding of the magnetohydrodynamic (MHD) processes in liquid metals, in this paper we propose an approach combining the classical methods in the dynamo theory…
Nearly Gaussian random variables and application to meteorology
Rui Gonçalves
We consider a nearly Gaussian random variable (see \cite{Lefebvre}) that, after a power transformation, the variable where , , is…
Universality in DAX index returns fluctuations
Rui Gonçalves, Helena Ferreira, Alberto Pinto
In terms of the stock exchange returns, we compute the analytic expression of the probability distributions F{DAX,+} and F{DAX,-} of the normalized positive and negative DAX (Germa…
Universality in the stock exchange
Rui Gonçalves, Alberto Pinto
We analyze the constituents stocks of the Dow Jones Industrial Average (DJIA30) and the Standard & Poor's 100 index (S&P100) of the NYSE stock exchange market. Surprisingly, we dis…
BHP universality and gaussianity in sunspot numbers fluctuations
R. Gonçalves, A. A. Pinto
We analyze the famous Wolf's sunspot numbers. We discovered that the distribution of the sunspot number fluctuations is a mixture of the BHP distribution with the Gaussian distribu…
River scaling analysis and the BHP universality hypothesis
Rui Gonçalves, Nico Stollenwerk, Alberto Pinto
The XY-model shows in two dimensions in the strong coupling regime a universal distribution, named BHP, which in turn also describes other models of criticality and self-organized…
