Mode-matching without root-finding: Application to a dissipative silencer [PDF]

open access: yes, 2006
This article presents an analytic mode-matching approach suitable for modelling the propagation of sound in a two-dimensional, three-part, ducting system.

ENTROPY OF LANGUAGE SYSTEM AS MAIN DEVELOPMENT INDICATOR

open access: yesSovremennye Issledovaniâ Socialʹnyh Problem, 2014
Article is devoted to the research of language system entropy. It is one of the main concept of synergetics and synergy. Entropy can be applied to description of language processes and detection of functioning and development features of language ...

Totally dissipative systems

open access: yes, 2005
In a totally dissipative behavior, all non-trivial trajectories dissipate energy. A characterization of such behaviors is given in terms of properties of the one- and two-polynomial matrices associated with the supply rate and with their kernel- and ...

Complex coupling effects and dissipative structure in nonlinear thermodynamic systems

open access: yesAIP Advances, 2019
It is well known that a dissipative structure can only possibly turn out when the nonlinear system is far away from the equilibrium. In this paper, the instability of steady state in an ideal system with two kinds of irreversible processes has been ...

PROBLEMS OF ECONOMY MANAGEMENT IN THE LIGHT OF COMPLEXITY THEORY

open access: yesУправленческие науки, 2015
The article presents the results of the fi research on the problems of governing a state with the use of the methodology of complexity theory (cybernetic epistemology) The toolkit allowed the authors to conclude that the complex, dissipative system of ...

Foraging Dynamics and Entropy Production in a Simulated Proto-Cell

open access: yesEntropy, 2022
All organisms depend on a supply of energetic resources to power behavior and the irreversible entropy-producing processes that sustain them. Dissipative structure theory has often been a source of inspiration for better understanding the thermodynamics ...

An Explanation of Energy Return on Investment From an Entropy Perspective

open access: yesFrontiers in Energy Research, 2021
Low-carbon energy transformation is a major trend in world energy development, and measures to mitigate carbon emissions can vary substantially in terms of the energy they require.

Simplified techniques for predicting the transmission loss of a circular dissipative silencer [PDF]

open access: yes, 2001
A closed-form analytical solution for the transmission loss of a dissipative silencer with a circular cross-section is described. The silencer contains a bulk reacting acoustic absorbent which is separated from a mean gas flow by a perforated screen ...
