The analysis presented in Sections 1.2 and 1.3 has shown that it is possible to calculate the thermodynamic characteristics of a real substance given only the ideal gas heat capacity and the volumetric EoS. However, the necessary information on the EoS is not always available for all fluids. Hen...
Let us consider a multi-stable system, which has two stable states, an unstable and a half stable equilibrium. A half stable equilibrium is a state in which one side is attractive, while on the other side is repulsive15. Namely, the half stable equilibrium corresponds to a nonlinear ...

This indicates that the surface mass balance should be positive at these altitudes according to the mass conservation equation (i.e., the equilibrium line is lower than these altitudes). Whereas, the annual 0 °C isotherm was estimated at an elevation of approximately 4200 m a.s.l. in...
The arrangement of the leaves can also have an influence on the burning characteristics of the plant. The ignition time was delayed with increasing leaf size [53]. In addition, weather influences such as wind can have a significant impact on the flammability of plants [54, 55]. In [55],...
Matrix [A] of the state-space model is the one connecting the two vectors in Eq. (8.102). The output equation is obtained based on Eq. (8.101): (8.103){h1h2}={y1y2}=[1001]·{x1x2}Matrix [C] of the state-space model is the identity matrix [I]; therefore, {x(0)} = {y(...
Thus a process line is an infinite succession of equilibrium states. A process line, therefore, may be imagined as the idealized limiting case of a real process carried out more and more slowly. Two additional special processes are illustrated in Figure 10.10. The process represented by the ...
