The Ostrovsky–Hunter equation governs evolution of shallow water waves on a rotating fluid in the limit of small high-frequency dispersion. Sufficient conditions for the wave breaking in the Ostrovsky–Hunter equation are found both on an infinite line and in a periodic domain. Using the method of characteristics, we also specify the blow-up rate at which the waves break. Numerical illustrations...

Tuned Liquid Dampers (TLD) are among passive control devices that have been used to suppress the vibration of structures in recent years. These structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. The TLD, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...

ur long term goal is to develop a tested model of optical properties in the surfzone and adjacent nearshore ocean, including the influence of suspended sediment and bubble population, to assess how optical properties are related to short term events such as individual breaking wave crests, and to determine how wave-driven surfzone circulation influences optical properties just offshore of break...

Our long term goal is to develop a tested model of optical properties in the surf zone and adjacent nearshore ocean, including the influence of suspended sediment, bubble population and surface foam, to assess how optical properties are related to short term events such as individual breaking wave crests, and to determine how wave-driven surf zone circulation influences spatial distribution of ...

Multiscale composite models based on the Bragg theOly are widely used to study the U1LlI<,,'l~"~' radar cross-section (NRCS) over the sea sllrface. However, these models are able to correctly reproduce the NRCS in ail configurations and wind wave conditions. have developed a physical model that takes into account, not only the Bragg nisl11, but also the non-Bragg scattering l11echanisl11 associ...

We develop a method for investigating the relationship between the shape of a 1-particle distribution and non-linear electrostatic oscillations in a collisionless plasma, incorporating transverse thermal motion. A general expression is found for the maximum sustainable electric field, and is evaluated for a particular highly anisotropic distribution. Introduction High-power lasers and plasmas m...

A semi-empirical model for surf zone wave height decay is adapted to the parabolic equation method in order to include the effect of depth-limited wave breaking in combined refraction/diffraction calculations. Several examples for plane beaches are presented in order to show correspondence between the empirical model, its numerical formulation, and previous laboratory data. The model is then ap...

This paper deals with the unconventional superconducting properties of Sr2RuO4, the best-known examples of p-wave superconductor with spin-triplet pairing. I shall first review the definition and rough classification of unconventional superconductivity. The formalism for p-wave spin-triplet pairing is examined. This will lead into the discussion of the most likely p-wave state for Sr2RuO4, its ...

The two-dimensional wave-breaking of relativistic plasma waves driven by a ultrashort high-power lasers, is described within a framework of cold 2-D fluid theory. It is shown that the transverse nonlinearity of the plasma wave results in temporally increasing transverse plasma oscillation in the wake of the laser pulse, inevitably inducing wave-breaking below the 1-D threshold. A condition for ...
