A hyperbolic model for the effects of urbanization on air pollution
TL;DR: In this article, a hyperbolic model to study effects of industrialization and urbanization on air pollution propagation is proposed, and the existence of smooth and discontinuous traveling wave-like solutions, related to the spread of both the pollution in the atmosphere and the level of urbanization, is discussed.
Journal ArticleDOI
Combined Frequency-Amplitude Nonlinear Modulation: Theory and Applications
Giancarlo Consolo,Vito Puliafito,Giovanni Finocchio,Luis Lopez-Diaz,Roberto Zivieri,Loris Giovannini,F. Nizzoli,Giovanna Valenti,Bruno Azzerboni +8 more
TL;DR: In this paper, a generalized theoretical model is proposed to describe the nonlinear dynamics observed in combined frequency-amplitude modulators whose characteristic parameters exhibit a nonlinear dependence on the input modulating signal.
Journal ArticleDOI
Spread of infectious diseases in a hyperbolic reaction-diffusion susceptible-infected-removed model.
TL;DR: A one-dimensional hyperbolic reaction-diffusion model of epidemics is developed to describe the dynamics of diseases spread occurring in an environment where three kinds of individuals mutually interact: the susceptibles, the infectives, and the removed.
Journal ArticleDOI
Pattern formation and modulation in a hyperbolic vegetation model for semiarid environments
TL;DR: In this paper, the authors present analytical and numerical investigations of pattern formation and modulation in a one-dimensional hyperbolic extension of the Klausmeier reaction-diffusion-advection vegetation model for semiarid environments.
Journal ArticleDOI
Mathematical modeling and numerical simulation of domain wall motion in magnetic nanostrips with crystallographic defects
TL;DR: In this article, the authors investigated the effect of spin-torque effects on magnetic nanostrips in the framework of the modified Landau-Lifshitz-Gilbert equation.
