Travelling waves and light-front approach in relativistic electrodynamics [PDF]
Ricerche di Matematica, 2018 We briefly report on a recent proposal (Fiore in J Phys A Math Theor 51:085203, 2018) for simplifying the equations of motion of charged particles in an electromagnetic (EM) field $F^{ }$ that is the sum of a plane travelling wave $F_t^{ }(ct\!-\!z)$ and a static part $F_s^{ }(x,y,z)$; it adopts the light-like coordinate $ =ct\!-\!z$ instead ...

Stress Wave Anisotropy in Centered Square Highly Nonlinear Granular Systems [PDF]
, 2012 Highly ordered, close packed granular systems present a nonlinear dynamic behavior stemming from the Hertzian contact interaction between particles. We investigated the propagation of elastic stress waves in an uncompressed, centered square array of ...

Fault Location of Lightning Strikes Using Residual Analysis Based on an Adaptive Kalman Filter
IEEE Access, 2019 Lightning strikes are the significant cause of transient, faults, and outages in electric power transmission and distribution systems. The double-exponential function is proposed to simulate the decaying part of the measured lightning current.

Traveling circumferential unstable wave of cylindrical flame front
Journal of Physics: Conference Series, 2016 The researches of stability of cylindrical front of deflagration combustion in an annular combustion chamber were made using phenomenological model. The flame front is described as discontinuity of gasdynamic parameters. It is considered that the combustion products are under chemical equilibrium. The combustible mixture and the combustion products are

Non-vanishing sharp-fronted travelling wave solutions of the Fisher–Kolmogorov model
Mathematical Medicine and Biology: A Journal of the IMA, 2022 Abstract The Fisher–Kolmogorov–Petrovsky–Piskunov (KPP) model, and generalizations thereof, involves simple reaction–diffusion equations for biological invasion that assume individuals in the population undergo linear diffusion with diffusivity $D$, and logistic proliferation with rate $\lambda $.

Geometric scaling as traveling waves [PDF]
, 2003 We show the relevance of the nonlinear Fisher and Kolmogorov-Petrovsky- Piscounov (KPP) equation to the problem of high energy evolution of the QCD amplitudes. We explain how the traveling wave solutions of this equation are related to geometric scaling,

Front Waves of Chemical Reactions and Travelling Waves of Neural Activity
, 2022 Travelling waves crossing the nervous networks at mesoscopic/macroscopic scales have been correlated with different brain functions, from long-term memory to visual stimuli. Here we investigate a feasible relationship between wave generation/propagation in recurrent nervous networks and a physical/chemical model, namely the Belousov–Zhabotinsky ...

Networks and Heterogeneous Media, 2006 We study a curvature-dependent motion of plane curves in atwo-dimensional cylinder with periodically undulatingboundary. The law of motion is given by $V=\kappa + A$, where$V$ is the normal velocity of the curve, $\kappa$ is the curvature,and $A$ is a ...
