    • Disentangling stochastic signals superposed with periodic oscillations 

      Kampers, Gerrit; Waechter, Matthias; Hoelling, Michael; Lind, Pedro; Queiros, Silvio D.A.; Peinke, Joachim (Physics Letters A;Volume 384, Issue 15, 29 May 2020, 126307, Journal article; Peer reviewed, 2020-02-05)
      We introduce a procedure for separating periodic oscillations superposed on a stochastic signal. The procedure combines empirical mode decomposition (EMD) of a signal with tools of data analysis based on stochastic ...

    • Small scale structures of turbulence in terms of entropy and fluctuation theorems 

      Fuchs, Andre; Queiros, Silvio D.A.; Lind, Pedro; Girard, Alain; Bouchet, Freddy; Wächter, Matthias; Peinke, Joachim (Physical Review Fluids;5, 034602, Journal article; Peer reviewed, 2020-03-11)
      We present experimental evidence that, together with the integral fluctuation theorem, which is fulfilled with high accuracy, a detailed-like fluctuation theorem holds for large entropy values in cascade processes in ...
