A Priori Assessment of Algebraic Flame Surface Density Models in the Context of Large Eddy Simulation for Nonunity Lewis Number Flames in the Thin Reaction Zones Regime

open access: yesJournal of Combustion, 2012
The performance of algebraic flame surface density (FSD) models has been assessed for flames with nonunity Lewis number (Le) in the thin reaction zones regime, using a direct numerical simulation (DNS) database of freely propagating turbulent premixed ...

Ternary Menger hyperalgebras: some algebraic properties

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In this article, we first establish an algebraic hyperstructure called a ternary Menger hyperalgebra of rank n, where n is a natural number. The algebraic hyperstructure can be regarded as a novel generalization of ternary semihypergroups. In particular,

New Stable Closed Newton-Cotes Trigonometrically Fitted Formulae for Long-Time Integration

open access: yesAbstract and Applied Analysis, 2012
The closed Newton-Cotes differential methods of high algebraic order for small number of function evaluations are unstable. In this work, we propose a new closed Newton-Cotes trigonometrically fitted differential method of high algebraic order which ...

A Construction of Rotated Lattices via Totally Real Subfields of the Cyclotomic Field Q(z_p)

open access: yesTrends in Computational and Applied Mathematics, 2019
The theory of lattices have shown to be useful in information theory and rotated lattices with high modulations diversity have been extensively studied as an alternative approach for transmission over a Rayleigh-fading channel, where the performance of ...

On the approximation of algebraic numbers by algebraic integers [PDF]

open access: yesJournal of the Australian Mathematical Society, 1963
In his Topics in Number Theory, vol. 2, chapter 2 (Reading, Mass., 1956) W. J. LeVeque proved an important generalisation of Roth's theorem (K. F. Roth, Mathematika 2,1955, 1—20).Let ξ be a fixed algebraic number, σ a positive constant, and K an algebraic number field of degree n.

Introductory Algebraic Number Theory [PDF]

open access: yes, 2003
Algebraic number theory is a subject which came into being through the attempts of mathematicians to try to prove Fermat's last theorem and which now has a wealth of applications to diophantine equations, cryptography, factoring, primality testing and ...
