This paper proposes a fundamental frequency tracker, with the specific purpose of comparing the automatic estimates with pitch contours that are sketched by trained phoneticians. The method uses a frequency domain approach to estimate pitch tracks that form minimum jerk trajectories. This method tries to mimic motor movements of the hand made while sketching. When the fundamental frequency trac...

Abstract. Linearizing the cosmological equation of state around the current epoch p = p0 + κ0 (ρ− ρ0) +O[(p− p0)2], is the simplest model one can consider that does not make any a priori restrictions on the nature of the cosmological fluid. Most popular cosmological models attempt to be “predictive”, in the sense that once some a priori equation of state is chosen the Friedmann equations are us...

Abstract The cosmological jerk parameter j is reconstructed in a non-parametric way from observational data independent of fiducial model. Cosmic Chronometer as well the Supernovae (the Pantheon compilation) are used for purpose. values found to be consistent with standard $$\Lambda $$ ? CDM model within $$2\...
