Properties of localized pulses through the analysis of temporal modulation effects in Bessel beams and the convolution theorem
(Elsevier Science BvAmsterdamHolanda, 2004)
Surface waves propagating on a turbulent flow
(AMER INST PHYSICS, 2016)
We study the propagation of monochromatic surface waves on a turbulent flow of liquid metal, when
the waves are much less energetic than the background flow. Electromagnetic forcing drives quasitwo-
dimensional turbulence ...
A mathematical model for wave propagation in elastic tubes with inhomogeneities: Application to blood waves propagation
(Elsevier B.V., 2007-12-15)
We study the propagation of waves in an elastic tube filled with an inviscid fluid. We consider the case of inhomogeneity whose mechanical and geometrical properties vary in space. We deduce a system of equations of the ...
Imaging radar observations and nonlocal theory of large-scale plasma waves in the equatorial electrojet
(European Geosciences Union (EGU), 2002)
Large-scale (λ∼1 km) waves in the daytime and nighttime equatorial electrojet are studied using coherent scatter radar data from Jicamarca. Images of plasma irregularities within the main beam of the radar are formed using ...
Supplement: " Localization and Broadband Follow-Up of the Gravitational-Wave Transient GW150914” (2016, ApJL, 826, L13)
(IOP, 2016)
This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare ...
Preliminary analysis of waves in the coastal zone of Monte Hermoso and Pehuén Co, Argentina
(Coastal Education & Research Foundation, 2012-07)
Coastal geomorphology is significantly influenced by waves because they are a major agent in removing and transporting sediments. Furthermore, any kind of human coastal activity is influenced by waves. Consequently, it is ...
Degeneration of internal Kelvin waves in a continuous twolayer stratification
(Cambridge Univ Press, 2015)
We explore the evolution of the gravest internal Kelvin wave in a two-layer rotating cylindrical
basin, using direct numerical simulations (DNS) with a hyperviscosity/diffusion approach to
illustrate different dynamic ...
Superluminal X-shaped beams propagating without distortion along a coaxial guide
(Amer Physical SocCollege PkEUA, 2002)
Coexistence of acoustic waves and turbulence in low Mach number compressible flows
(American Institute of Physics, 2019-04-04)
In this work, direct numerical simulations of the compressible fluid equations in turbulent regimes are performed. The behavior of the flow is either dominated by purely turbulent phenomena or by the generation of sound ...
Numerical study of the generation and propagation of ultralow-frequency waves by artificial ionospheric F region modulation at different latitudes
(European Geosciences Union, 2016-09-21)
Powerful high-frequency (HF) radio waves can be used to efficiently modify the upper-ionospheric plasmas of the F region. The pressure gradient induced by modulated electron heating at ultralow-frequency (ULF) drives a ...
