Twins in relativistic spacetimes: dispelling some misconceptions
T. A. A. da Câmara, P. S. Lemos, M. O. Calvão +1
In contrast to Newtonian physics, there is no absolute time in relativistic (Lorentzian) spacetimes. This immediately implies that two twins may, in general, age at different rates…
Can Lorentz transformations be determined by the null Michelson-Morley result?
J. A. S. Lima, F. D. Sasse
The so-called principle of relativity is able to fix a general coordinate transformation which differs from the standard Lorentzian form only by an unknown speed which cannot in pr…
Obtaining the Quantum Fourier Transform from the Classical FFT with QR Decomposition
F. L. Marquezino, R. Portugal, F. D. Sasse
We present the detailed process of converting the classical Fourier Transform algorithm into the quantum one by using QR decomposition. This provides an example of a technique for…
Nonexistence of Petrov type III Space-Times on which Weyl's Neutrino Equation or Maxwell's Equations satisfy Huygens' Principle
R. G. McLenaghan, F. D. Sasse
Extending previous results we show that there are no Petrov type III space-times on which either the Weyl neutrino equation or Maxwell's equations satisfy Huygens' principle. We pr…
Obtaining Membership Functions from a Neuron Fuzzy System extended by Kohonen Network
Angelo Luis Pagliosa, Claudio Cesar de Sa, Fernando D. Sasse
This article presents the Neo-Fuzzy-Neuron Modified by Kohonen Network (NFN-MK), an hybrid computational model that combines fuzzy system technique and artificial neural networks.…
