In high-pressure dynamic thermodynamic processes, the pressure is much higher than the air critical pressure, and the temperature can deviate significantly from the Boyle temperature. In such situations, the thermo-physical properties and pneumatic performance can’t be described accurately by the ideal gas law. This paper proposes an approach to evaluate the pneumatic performance of a high-pres...

The equation of state (EOS) is a nontrivial relation linking the thermodynamic variables specifying the state of a physical system . The best known example of EOS is Boyle’s ideal gas law, stating that the pressure of a collection of N noninteracting, pointlike classical particles, enclosed in a volume Ω, grows linearly with the temperature T and the average particle density n = N/Ω. The ideal ...

Natural theology is reading the book of nature, not the book of revelation, for knowledge of God. Natural theology, as a category employed by practitioners, originated within the history of Christianity, as passages from the New Testament such as Romans 1:20 raised the possibility of knowledge about God without revelation. The best-known work of natural theology is William Paley’s (d. 1805 AD) ...

Aggregating and sequencing of the content units is at the core of e-learning theories and standards. We discuss the aggregating/sequencing problems in the context of using generative learning objects (GLOs). Proposed by Boyle, Morales, Leeder in 2004, GLOs provide more capabilities, focus on quality issues, and introduce a solid basis for a marked improvement in productivity. We use meta-progra...

A framework for understanding the geometry of continuous actions of Z was developed by Boyle and Lind using the notion of expansive behavior along lower-dimensional subspaces. For algebraic Z-actions of entropy rank one, the expansive subdynamics is readily described in terms of Lyapunov exponents. Here we show that periodic point counts for elements of an entropy rank one action determine the ...

The condition (1.1) on λ1, . . . , λn is a well–known necessary condition for n numbers to be the eigenvalues of an n× n nonnegative matrix (see, for example, Berman and Plemmons [3]). Furthermore, from a result due to Friedland [6, Theorem 1], it is known that (1.1) implies that one of the λi’s is nonnegative and majorizes the moduli of the remaining numbers. Assume for the moment, without los...
