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

Journal 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

Қарағанды 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

Abstract 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)

Trends 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]

Journal 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.

The views and experiences of Grade 3 teachers in developing learners’ algebraic representations

Pythagoras
The global concern over low mathematical achievement consistently challenges educational ministries. Poor development of learners’ algebraic representations contributes to poor mathematical achievement from the Foundation Phase classes (Grades 1–3).

Aspects of derivative causality in bond-graph models

MATEC Web of Conferences, 2017
The bond-graph method used in the analysis of system dynamics problems leads to a system containing a number of differential equations equal to the number of energy storing elements in integral causality and a number of algebraic equations equal to the ...
