Tendency towards maximum complexity in a nonequilibrium isolated system.

چکیده
The time evolution equations of a simplified isolated ideal gas, the "tetrahedral" gas, are derived. The dynamical behavior of the López-Ruiz-Mancini-Calbet complexity [R. López-Ruiz, H. L. Mancini, and X. Calbet, Phys. Lett. A 209, 321 (1995)] is studied in this system. In general, it is shown that the complexity remains within the bounds of minimum and maximum complexity. We find that there are certain restrictions when the isolated "tetrahedral" gas evolves towards equilibrium. In addition to the well-known increase in entropy, the quantity called disequilibrium decreases monotonically with time. Furthermore, the trajectories of the system in phase space approach the maximum complexity path as it evolves toward equilibrium.

On the Problem of Formulating Principles in Nonequilibrium Thermodynamics
In this work, we consider the choice of a system suitable for the formulation of principles in nonequilibrium thermodynamics. It is argued that an isolated system is a much better candidate than a system in contact with a bath. In other words, relaxation processes rather than stationary processes are more appropriate for the formulation of principles in nonequilibrium thermodynamics. Arguing th...
متن کاملSteepest entropy ascent model for far-nonequilibrium thermodynamics: unified implementation of the maximum entropy production principle.
By suitable reformulations, we cast the mathematical frameworks of several well-known different approaches to the description of nonequilibrium dynamics into a unified formulation valid in all these contexts, which extends to such frameworks the concept of steepest entropy ascent (SEA) dynamics introduced by the present author in previous works on quantum thermodynamics. Actually, the present f...
متن کاملBridging the ‘Two Cultures’ of Research and Service: Can Complexity Theory Help?; Comment on “Experience of Health Leadership in Partnering With University-Based Researchers in Canada – A Call to ‘Re-imagine’ Research”
This commentary addresses Bowen et al’s empirical study of perspectives of Canadian healthcare staff towards research and their call for multi-faceted action to improve misalignments in the system. This commentary argues that tensions and misalignments between research and service are inherent and can never be eradicated. Building on previous work by Lanham et al, I pro...
متن کاملKnowledge Translation in Healthcare – Towards Understanding its True Complexities; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
This commentary argues that to fully appreciate the complexities of knowledge transfer one firstly has to distinguish between the notions of “data, information, knowledge and wisdom,” and that the latter two are highly context sensitive. In particular one has to understand knowledge as being personal rather than objective, and hence there is no form of knowledge that a-priori is more authoritat...

The roles and effects of changes in syntax on comprehension and processing effort, and the relationships between these two, comprise a large and separate field of inquiry, with the general belief now in place that such changes and variations bring about varied psycholinguistic and discursive implications for comprehension, manifesting themselves differently in different genres.The current study...
