In [125] it is shown at some length how this homology permits the natural transfer of renormalization methods from statistical mechanics to information theory, producing phase transitions and analogs to evolutionary punctuation in systems characterized by piecewise, adiabatically stationary, ergodic information sources.
The first interpretation [46] to IB's was done within the framework of the strong coupling limit of the particle-rotor model, in which one or more particles are coupled to a rotating deformed core and follow the rotation adiabatically.
All the walls were treated adiabatically and, hence, the normal gradients of temperature were set equal to zero at all fluid-wall interfaces.
The fact that work can be done adiabatically on a system, with no change in the energy stored within its boundaries (Zimmels, 1995, 1996a,b;1997;1999; 2002), and energy of a system can be changed with no work or heat delivered in its own frame of reference, calls for reformulation of the first law in the presence of fields.
The second hypothesis is that the walls of the combustion chamber adiabatically isolate the internal flow, meaning that are no loses of heat produced during the combustion.
For [delta][omega] [much less than] 0 the atoms follow the driving field adiabatically and thus the radio frequency and the light modulation oscillate in phase.
However, it has more recently been argued that plane strain impact fracture in thermoplastics results from adiabatically activated decohesion (21).
Assuming that the pressure drop across the combustion process is negligible and the process takes place adiabatically, the enthalpy at State 3 was calculated and the corresponding entropy and temperature were determined.
This fact, coupled with a probably high value for the stellar absorption coefficient, enables us to ascribe a temperature T at each point P such that the properties of an element of mass in the neighborhood of P are the same as if it were adiabatically inclosed in an inclosure at a temperature T" [24, p.
If the direction of the magnetic field is changed adiabatically, i.
