The resulting entropy balance for a closed system of mass m is given by integrating Eq. (7.48) and substituting in Eqs. (7.60), (7.62), (7.65), and (7.69) to produce General closed system entropy balance (SB) (7.75)∫τ∫Σ(q˙Tb)actdA dt+1(SP)2=(S2−S1)system=[m(s2−...
This is the entropy balance for a closed system. The increase of entropy principle (closed system) The entropy change can be evaluated independently of the process details. However, the entropy generation depends on the process, and thus it is not a property of the system. ...

When should high entropy be interpreted as a healthy sign, and when as marker of deteriorating health? We address this question for the particular case of human standing balance and the Center of Pressure data.Methods: We have measured and analyzed balance data of 136 participants (young, n =...

The minimization of the Gibbs free energy is a form of the , which follows from the for closed systems. Moreover, the Gibbs free energy equation, in modified form, can be utilized for when terms are included in the energy balance equation. In a popular 1982 textbook, by noted American bi...
This discussion indicates that, even though I(X,Y,f) gives rise to a general learning criterion, there's room for choosing information-based criteria that properly balance the terms S(Y) and S(Y|X,f). Unified learning principles: S(Y|X) and I(X|Y) are more general than relative ...
Often equilibrium can be replaced by a term such as stability or balance. Homeostasis can be viable concept, as can entropy, which among other things has potential for aiding in the integration of theory and method. 展开 关键词: Bibliography, Theoretical or Mathematical/ system theory/ system ...
To obtain the total generation of entropy in a thermofluidic system at the system level, the following general equation for a control volume medium is given as: (1.1)dsdt=∑m˙sin−∑m˙sout+∑Q˙T+S˙gen,tot This equation, as it is seen from the left-hand side, provides the real...
