Analysis of wave scattering from non-symmetric discontinuities in one-dimensional wave-guides
(2017-01-01)
Predicting the scattering from waves that are incident on a damaged section of structure is of importance in structural health monitoring and nondestructive testing techniques to detect dam-age. High frequency waves are ...
Electro-optical Modeling Of High Power Semiconductor Laser For 800 Nm Emission With An Ingaasp/gaas/ingap Quantum Hetero Structure

Dynamic and kinematic characterization of the impulsive wavemaker system in a numerical wave tank
(Amer Inst. Physics, 2020)
We study the dynamical response of a piston-type wavemaker in a numerical wave tank. The two-dimensional, fully viscous unsteady Navier-Stokes equations are solved on a two-phase flow configuration using the volume of fluid ...
Preliminary multiheight radar observations of waves and winds in the mesosphere over Jicamarca
(Elsevier, 1977-09)
The Jicamarca Radio Observatory receives strong radar echoes from the mesosphere. This paper reports preliminary results of simultaneous measurements of echo power, radial velocity, and spectral width at 12 mesospheric ...
Subluminal wave bullets: Exact localized subluminal solutions to the wave equations

Um panorama sobre roll waves em escoamentos laminares e turbulentos com superfície livre
(Universidade Estadual Paulista (Unesp), 2007-12-07)
Os escoamentos na superfície livre que se processam sobre forte declividade podem desenvolver instabilidades ao cabo de tempo finito. Tais instabilidades aparecem sob formas de ondas tipo “hydraulic jumps” bem espaçados e ...

Frequency tunable continuous THz wave generation in a periodically poled fiber
(Ieee-inst Electrical Electronics Engineers Inc, 2015-05-01)
An all-fiber approach to terahertz generation using a periodically poled optical fiber is proposed and experimentally demonstrated. In the proposed approach, a continuous-wave THz wave is generated at a periodically poled ...
SEARCH for MONOCHROMATIC SIGNALS USING DATA FROM the ALLEGRO GRAVITATIONAL WAVE DETECTOR
(World Scientific Publ Co Pte Ltd, 2010-08-01)
We present a data analysis method for searching monochromatic signals in temporal series. With this method it is possible to estimate the power spectrum by using averaged modified periodograms which reinforce the presence ...
