On a model for the growth of an invasive avascular tumor
(2013-08-30)
This paper is devoted to study the 1D model of invasive avascular tumor growth, which takes into account cell division, death, and motility, proposed by Kolobov and collaborators in 2009. First, we examine the existence ...
Nonlocal anisotropic dispersal with monostable nonlinearity
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-06-15)
We study the travelling wave problem
J * u - u - cu' + f(u) = 0 in R, u(-infinity) = 0, u(+infinity) = 1
with an asymmetric kernel J and a monostable nonlinearity. We prove the existence of a minimal speed, and under ...

Proteção de linhas de transmissão aéreas de sistemas LCC-HVDC monopolares baseada em ondas viajantes utilizando um terminal
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2018-08-03)
In general, the conventional direct current transmission lines systems, LCC (Line
Commutated Converter) systems, present great lengths, which increase the fault occurrence
rate and, consequently, the demands on the ...

Front propagation and quasi-stationary distributions for one-dimensional Lévy processes
(Univ Washington, 2016-09)
We jointly investigate the existence of quasi-stationary distributions for one dimensional Lévy processes and the existence of traveling waves for the Fisher-Kolmogorov-Petrovskii-Piskunov (F-KPP) equation associated with ...
