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 ...

The Makeenko-Migdal equation for Yang-Mills theory on compact surfaces [PDF]

open access: yes, 2017
We prove the Makeenko-Migdal equation for two-dimensional Euclidean Yang-Mills theory on an arbitrary compact surface, possibly with boundary. In particular, we show that two of the proofs given by the first, third, and fourth authors for the plane case ...

Noncommutative Burgers Equation [PDF]

open access: yes, 2003
We present a noncommutative version of the Burgers equation which possesses the Lax representation and discuss the integrability in detail. We find a noncommutative version of the Cole-Hopf transformation and succeed in the linearization of it.

Heun equation, Teukolsky equation, and type-D metrics

open access: yes, 2007
Starting with the whole class of type-D vacuum backgrounds with cosmological constant we show that the separated Teukolsky equation for zero rest-mass fields with spin $s=\pm 2$ (gravitational waves), $s=\pm 1$ (electromagnetic waves) and $s=\pm 1/2 ...
