AIP Conference Proceedings, 2008 Using Planck scale oscillators in the background dark energy in a model that parallels the theory of phonons, we deduce the Planck mass, the elementary particle mass scale, the mass of the Universe and a recently discovered residual energy in the cosmic ...

Thermodynamic potentials and thermodynamic relations in nonextensive thermodynamics [PDF]
Physica A: Statistical Mechanics and its Applications, 2011 The generalized Gibbs free energy and enthalpy is derived in the framework of nonextensive thermodynamics by using the so-called physical temperature and the physical pressure. Some thermodynamical relations are studied by considering the difference between the physical temperature and the inverse of Lagrange multiplier.

Algorithmic thermodynamics [PDF]
Mathematical Structures in Computer Science, 2012 Algorithmic entropy can be viewed as a special case of the entropy studied in statistical mechanics. This viewpoint allows us to apply many techniques developed for use in thermodynamics to the subject of algorithmic information theory. In particular, suppose we fix a universal prefix-free Turing machine and letXbe the set of programs that halt for ...

Thermodynamics Far from the Thermodynamic Limit [PDF]
The Journal of Physical Chemistry B, 2017 Understanding how small systems exchange energy with a heat bath is important to describe how their unique properties can be affected by the environment. In this contribution, we apply Landsberg's theory of temperature-dependent energy levels to describe the progressive thermalization of small systems as their spectrum is perturbed by a heat bath.

Enhancing the performance of a heating, ventilation, and air conditioning system using ice slurry [PDF]
E3S Web of ConferencesThis article examines the impact of different ice-slurry fractions on the cooling performance of an HVAC system. The findings reveal that increasing the ice percentage in the ice-slurry solution leads to a proportional enhancement in the system’s cooling

Measuring thermodynamic length [PDF]
, 2007 Thermodynamic length is a metric distance between equilibrium thermodynamic states. Among other interesting properties, this metric asymptotically bounds the dissipation induced by a finite time transformation of a thermodynamic system.
