Numerical simulation of the lubricant performance
(Elsevier Science Sa, 2008-03)
Due to the high pressures that are involved in tube hydroforming processes, high values of the friction forces are developed and, therefore, lubricants are usually employed to increase the formability of the workpiece. ...
Wannier threshold theory for the description of the two-electron cusp in the ion-induced double ionization of atoms
(Elsevier, 2016-02-15)
The double electron capture into the continuum states of the projectile (double ECC) is investigated theoretically in collisions of 100 keV He2+ ions with He atoms. The process is described within the framework of the ...
One and The Same Route: Two Outstanding Electrodynamics
(Sociedade Brasileira de Física, 1998-03-01)
We show that the same route that leads to Maxwell's electrodynamics leads also to Podolsky's electrodynamics, provided we start from Podolsky's electrostatic force law instead of the usual Coulomb's law.
Podolsky's higher-order electromagnetism from first principles
(1997-07-01)
Podolsky's higher-order field equations are obtained by generalizing the laws of Podolsky's electrostatics, which follow from Coulomb's generalized law and superposition, to be consistent with special relativity. In addition, ...
Solution of Mathisson-Papapetrou-Dixon Equations for Spinning Test Particles in a Kerr Metric
One of the purposes of this thesis is to study the gravitomagnetic effects. These effects are derived by the analogy between Coulomb’s law and Newton’s gravitation law. There is a relationship between Maxwell’s equations ...
HOW CAN ONE PROBE PODOLSKY ELECTRODYNAMICS?
(World Scientific Publ Co Pte Ltd, 2011-08-20)
We investigate the possibility of detecting the Podolsky generalized electrodynamics constant a. First we analyze an ion interferometry apparatus proposed by B. Neyenhuis et al. (Phys. Rev. Lett. 99, 200401 (2007)), who ...
LIMITS on THE COUPLING CONSTANT of HIGHER-DERIVATIVE ELECTROMAGNETISM
(World Scientific Publ Co Pte Ltd, 2010-02-10)
We investigate a higher-derivative version of QED constructed by adding to the Maxwell's Lagrangian a term containing second-order derivatives of the electromagnetic potentials. The resulting Lagrangian, besides being gauge ...
A finite strain contact model for mixed lubricated surfaces in forming processes
(Elsevier, 2013-06)
For an accurate simulation of forming processes, it is of paramount importance to model the different lubrication regimes that can develop at the contact interface. These might vary from zone to zone of the forming piece, ...
La aplicación de la interfaz gráfica de usuario (gui) a la enseñanza y aprendizaje de algunos temas de electromagnetismo
(17/06/2015)
ABSTRACT: This work purposes to explore the possibility of using the computer through a Graphic User Interface (GUI) as a didactic tool for the teaching of physics, specifically Electromagnetism. As justifying elements ...
