A Determinant of Stirling Cycle Numbers Counts Unlabeled Acyclic Single-Source Automata [PDF]

open access: diamondDiscrete Mathematics & Theoretical Computer Science, 2008
We show that a determinant of Stirling cycle numbers counts unlabeled acyclic single-source automata. The proof involves a bijection from these automata to certain marked lattice paths and a sign-reversing involution to evaluate the determinant.

The variance of the Stirling cycle numbers

open access: green, 2005
We show that the probability that two permutations of $n$ letters have the same number of cycles is \[\sim \frac{1}{2\sqrt{ \log{n}}}.\]

Thermoeconomic analysis of an irreversible Stirling heat pump cycle [PDF]

open access: greenThe European Physical Journal B - Condensed Matter and Complex Systems, 2006
In this paper an analysis of the Stirling cycle in thermoeconomic terms is developed using the entropy generation. In the thermoeconomic optimization of an irreversible Stirling heat pump cycle the F function has been introduced to evaluate the optimum for the higher and lower sources temperature ratio in the cycle: this ratio represents the value ...

Analytical Solutions and Optimization of the Exo-Irreversible Schmidt Cycle with Imperfect Regeneration for the 3 Classical Types of Stirling Engine Solutions analytiques et optimisation du cycle de Schmidt irréversible à régénération imparfaite appliquées aux 3 types classiques de moteur Stirling [PDF]

open access: diamondOil & Gas Science and Technology, 2011
The “old” Stirling engine is one of the most promising multi-heat source engines for the future. Simple and realistic basic models are useful to aid in optimizing a preliminary engine configuration.

Stirling Thermodynamics using Phasor Notation [PDF]

open access: yesE3S Web of Conferences, 2021
Phasor mathematics is used to develop the isothermal Stirling cycle and extended to the ideal adiabatic Stirling cycle. The results are developed for piston – piston (alpha) machines and displacer – piston (beta and gamma) machines.
