Gradient Vector Flow Models for Boundary Extraction in 2D Images
Gilson A. Giraldi, Leandro S. Marturelli, Paulo S. Rodrigues
The Gradient Vector Flow (GVF) is a vector diffusion approach based on Partial Differential Equations (PDEs). This method has been applied together with snake models for boundary e…
Electron Landau damping in a laboratory dipole magnetic field plasma
Nikolay I. Grishanov, Abimael F. D. Loula, Carlos A. De Azevedo +1
Transverse and longitudinal dielectric permittivity elements are derived for radio frequency waves in a laboratory dipole magnetic field plasma (LDMFP) accounting for the finite ri…
Collisionless wave dissipation in a D-shaped tokamak with Soloviev type equilibrium
Nikolay I. Grishanov, Abimael F. D. Loula, Alexandre L. Madureira +1
Parallel permittivity elements are derived for radio frequency waves in an axisymmetric D-shaped tokamak with Soloviev type equilibrium under arbitrary aspect ratio, arbitrary elon…
Influence of bounce resonance effects on the cyclotron wave instabilities in dipole magnetospheric plasmas with anisotropic temperature
Nikolay I. Grishanov, Marco A. Raupp, Abimael F. D. Loula +1
In this paper, we derive the dispersion equations for field-aligned cyclotron waves in an axisymmetric dipole magnetospheric plasmas with both the bi-Maxwellian and bi-Lorentzian d…
Information Processing in Brain Microtubules
Jean Faber, Renato Portugal, Luiz Pinguelli Rosa
Models of the mind are based on the possibility of computing in brain microtubules. From this point of view, information processing is the fundamental issue for understanding the b…
