Dendriform equations

open access: yesJournal of Algebra, 2009
We investigate solutions for a particular class of linear equations in dendriform algebras. Motivations as well as several applications are provided. The latter follow naturally from the intimate link between dendriform algebras and Rota-Baxter operators, e.g. the Riemann integral or Jackson's q-integral.

FINITE ELEMENT ANALYSIS OF HEAT TRANSFER ON THE ACTIVE SURFACE OF CUTTING TOOLS [PDF]

open access: yesJournal of Research and Innovation for Sustainable Society, 2020
The finit elements method is a procedure of solving a large variety of engeneering problems with the assistance of the computer. In this paper we will analyze the way in which the heat distribution is made in the contact area between the part and the ...

Viscosity Model of Polymer Extract from Irvingia Gabonensis [PDF]

open access: yesComputational Engineering and Physical Modeling, 2023
Generally, the viscosity of polymers decrease as temperature increases and it increases as concentration increases, but the rates of these changes are largely dependent on the source of the polymer.

A kinetic eikonal equation [PDF]

open access: yes, 2012
We analyse the linear kinetic transport equation with a BGK relaxation operator. We study the large scale hyperbolic limit $(t,x)\to (t/\eps,x/\eps)$. We derive a new type of limiting Hamilton-Jacobi equation, which is analogous to the classical eikonal ...

Tetrahedron Reflection Equation [PDF]

open access: yes, 1997
Reflection equation for the scattering of lines moving in half-plane is obtained. The corresponding geometric picture is related with configurations of half-planes touching the boundary plane in 2+1 dimensions.
