Heat Transfer: Volume 1, 2005 The present work is a numerical simulation of the, piloted, non-premixed, methane–air flame structure in a new mathematical imaging domain. This imaging space has the mixture fraction of diffusion flame Z1 and mixture fraction of pilot flame Z2 as independent coordinates to replace the usual physical space coordinates. The predications are based on the

Mathematical analysis of a scalar multidimensional conservation law with discontinuous flux [PDF]
Journal of Evolution Equations, 2011 We deal in this paper with a scalar conservation law, set in a bounded multidimensional domain, and such that the convective term is discontinuous with respect to the space variable. First, we introduce a weak entropy formulation for the homogeneous Dirichlet problem associated with the first-order reaction-convection equation that we consider.

Optimal control of mathematical models for the radiotherapy of gliomas: the scalar case
Computational and Applied Mathematics, 2016This paper deals with the optimal control of a mathematical model of glioma progression incorporating the basic facts of the evolution of primary brain tumors. We will consider a model of the simplest possible kind, based on the Fischer-Kolmogorov equations, using ideas from Perez-Garcia (Mathematical models for the radiotherapy of gliomas (preprint ...

Mathematical Modeling of Soliton-like Solutions in the Scalar-tensor Theories of Gravity
AIP Conference Proceedings, 2009In the present, work we find new numerical solutions describing soliton‐like objects coupled to non‐linear electrodynamics in the scalar‐tensor theories of gravity. Approximate solutions have been also obtained and a comparison to the numerical results has been made.

Relative distance between two scalar fields. Application to mathematical modelling approximation
Mathematical Methods in the Applied Sciences, 2013AbstractInspired in the relative error between two quantities, we define a functional ΔD that operates on two non‐negative scalar fields, which are integrable in a given open connected set D. We prove that ΔD defines a metric, but not an ultrametric nor a translation invariant metric.

An Extension Of The Mathematical Framework For A Scalar Universe
These two papers provide an enhanced understanding of my conceptual framework. Through advanced computer software I was able to derive the equations for all forces in scale to c while defining c's role as the upper and lower transformation rate. Essentially where reality begins to resolve in 3D space like we know it.openaire +1 more source
More Mathematical Proofs To Define A Unified Scalar Theory
The purpose of this paper is to serve as a computational proof of concept for my "Unified Theory Of Scalability". The contents of this paper show an extended framework for the intitial logic pattern that was described in the original super formula Z = (X•(A/B)•Y)^tWhere the bounds of the system are set to where the highest and lowest order ...openaire +2 more sources
Mathematical Modeling for scalar sscalar interface problems between dielectric and metamaterial
2013Some electromagnetic materials have, in a given frequency range, an e ective dielectric permittivity and/or a magnetic permeability which are real-valued negative coe cients when dissipa- tion is neglected. They are usually called metamaterials. We study a scalar transmission problem between a classical dielectric material and a metamaterial, set in an
