Integral of the boltzmann factor

Journal of Thermal Analysis, 1996
A new approximation is proposed to the integral of the Boltzmann factor: $$\int\limits_0^T {e^{ - E/RT} dT} $$ and is shown to be more accurate than the existing approximations over the entire range of values ofE/RT, including low values.

Factoring Ideals in Integral Domains

2013
A classical generalization of the Fundamental Theorem of Arithmetic states that an integral domain is a principal ideal domain if and only if each of its proper ideals can be factored as a finite product of principal prime ideals. If the “principal” restriction is removed, one has a characterization of (nontrivial) Dedekind domains. The purpose of this

On Integrating Factors and a Perturbation Method

Volume 3A: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration of Nonlinear, Random, and Time-Varying Systems, 1995
Abstract In this paper the fundamental concept (due to Euler, 1734) of how to make a first order ordinary differential equation exact by means of integrating factors, is extended to n-th order (n ≥ 2) ordinary differential equations and to systems of first order ordinary differential equations.

Time as the Integrative Factor

New Directions for Adult and Continuing Education, 1999
AbstractHow adults change over time is best understood through a consideration of the intersection of historical time period, chronological age (life time), and the culturally specific social timetable that orders major life events.

Factorization in Integral Domains

The Mathematics Teacher, 1966
The noun “factor” in mathematics quite generally denotes an element appearing in an expression that indicates that the element is to be multiplied by another element. Similarly, the transitive verb “to factor” means to express a given element as a product of factors.

Factorization and integration in Reduce

1991
Abstract The purpose of this chapter is to give an introduction to the algorithms employed by two of the most important of Reduce’s algebraic packages, namely the factorizer and integrator, without, however, going in full detail into the underlying pure mathematics.

Write a func dwr that accepts two inputs a, b, checks that they are integers and that b is not zero, and returns the pair [a div b, a mod b].
