GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs [PDF]

open access: yes, 2018
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of the Advanced gravitational-wave detector network. During the first

A new approach to investigate wave dissipation in viscoelastic tubes: Application of wave intensity analysis [PDF]

open access: yes, 2005
Wave dissipation in elastic and viscoelastic medium has been investigated extensively in the frequency domain. The aim of this study is to examine the pattern of wave dissipation in the time-domain using wave intensity analysis.

High-order rogue waves of a long wave-short wave model [PDF]

open access: yes, 2018
The long wave-short wave model describes the interaction between the long wave and the short wave. Exact higher-order rational solution expressed by determinants is calculated via the Hirota's bilinear method and the KP hierarchy reduction.

Advanced Virgo: a second-generation interferometric gravitational wave detector [PDF]

open access: yes, 2014
Advanced Virgo is the project to upgrade the Virgo interferometric detector of gravitational waves, with the aim of increasing the number of observable galaxies (and thus the detection rate) by three orders of magnitude. The project is now in an advanced

WAVE-WAVE INTERACTIONS, CURRENT-WAVE INTERACTIONS AND RESULTING EXTREME WAVES AND BREAKING WAVES

open access: yesCoastal Engineering Proceedings, 1980
The influence of an opposing current on highly non-linear transient breaking waves in deep water is described quantitatively from experiments. 3 new parameters that describe crest front steepness and wave asymmetry are introduced. Further, joint probability density distributions are obtained from an analysis of field data containing nearly 25000 storm ...
