Time-Reversibility in Atmospheric Dispersion
Due to the chaotic nature of atmospheric dispersion, small deviations, e.g., numerical errors in dispersion simulations, increase rapidly over time. Therefore, the accuracy of backward simulations is limited. In the paper, the degree of the fulfillment of time-reversibility over different time periods is investigated by a Lagrangian dispersion model at a global scale using pollutant clouds cons...
متن کاملTime Reversibility for Modular
We start with a modular K-system that possesses Anosov endomorphisms in both time directions. We extend the system via a crossed product construction. If one of the Anosov endomorphisms can be extended, then also the other one. Also the extensions form a Moebius group and allow a time reeection operator that implements on the algebra an antiisomorphism.

متن کاملAudibility of temporal smearing and time misalignment of acoustic signals
Misalignment in timing between drivers in a speaker system and temporal smearing of signals in components and cables have long been alleged to cause degradation of fidelity in audio reproduction. It has also been noted that listeners prefer higher sampling rates (e.g., 96 kHz) than the 44.1 kHz of the digital compact disk, even though the 22 kHz Nyquist frequency of the latter already exceeds t...
متن کاملOn Time Reversibility of Linear Time Series
In this paper we suggest a procedure for testing reversibility of time series. Our approach is based on a necessary and sufficient condition for time reversibility of linear models. An attractive feature of the procedure is that in converse with other approaches it doesn’t require important assumptions, especially existence of moments of order higher than two. Our simulation confirms the proced...
