Collisionless stellar systems are driven towards equilibrium by mixing of phase-space elements. I show that the excess-mass function D( f ) = ∫ F̄(x,v)> f (F̄(x, v) − f ) d3xd3v (with F̄(x, v) the coarse-grained distribution function) always decreases on mixing. D( f ) gives the excess mass from values of F̄(x, v) > f . This novel form of the mixing theorem extends the maximum phase-space density a...

In this paper, an adaptive blind dereverberation method based on speech generative model is presented. Our ICA-based speech generative model can decompose speeches into independent sources. Experimental results show that the proposed blind dereverberation model successfully performs even in non-minimum phase channels.

The estimation of glottal flow with inverse filtering requires typically subjective evaluation of the obtained flow waveforms by the experimenter. In this paper, we propose a straightforward method that yields an objective analysis tool to be used in the assessment of the quality of inverse filtered glottal flow estimates. The method computes the negative derivative of the phase response, the g...

Thermodynamical properties of nuclear matter undergoing multifragmentation are studied within a simplified version of the statistical model. An exact analytical solution has been found for the grand canonical ensemble. Excluded volume effects are taken into account in the thermodynamically self-consistent way. In thermodynamic limit the model exhibits a first order liquid-gas phase transition w...

An exact analytical solution of the statistical multifragmentation model is found in thermodynamic limit. The model exhibits a 1-st order phase transition of the liquid-gas type. The mixed phase region of the phase diagram, where the gas of nuclear fragments coexists with the infinite liquid condensate, is unambiguously identified. The peculiar thermodynamic properties of the model near the bou...

An exact analytical solution of the statistical multifragmentation model is found in thermodynamic limit. Excluded volume effects are taken into account in the thermodynamically self-consistent way. The model exhibits a 1-st order phase transition of the liquid-gas type. An extension of the model including the Fisher’s term is also studied. The possibility of the second order phase transition a...
