Avoided intersections of nodal lines

, 2002
We consider real eigen-functions of the Schr\"odinger operator in 2-d. The nodal lines of separable systems form a regular grid, and the number of nodal crossings equals the number of nodal domains.

OWC-Type Wave Chamber Optimization Under Series of Regular Waves

Arabian Journal for Science and Engineering, 2015
Oceans cover more than 70 % of the Earth’s surface, and water waves are considered as unlimited sources of renewable energy. The use of fossil fuels may cause undesired challenges such as global warming and climate change in the nature. Advantages of renewable energy include low operational cost, environment friendliness, simple maintenance procedures,

Experimental Investigation on Wave Dissipation of Perforated Pipe Breakwater Under Regular Wave Conditions

Journal of Marine Science and Engineering
The permeable breakwater is an innovative, eco-friendly coastal protection structure that reduces wave impact while minimizing “dead water” and environmental harm. This study introduces a perforated pipe breakwater design with an increasing pipe diameter

Optimum Placement of Post-1PN GW Chirp Templates Made Simple at any Match Level via Tanaka-Tagoshi Coordinates

, 2001
A simple recipe is given for constructing a maximally sparse regular lattice of spin-free post-1PN gravitational wave chirp templates subject to a given minimal match constraint, using Tanaka-Tagoshi coordinates.Comment: submitted to Phys. Rev.

Experimental study on the evolution of submerged artificial sandbar-beach profile under the regular waves condition

Frontiers in Marine Science
Submerged artificial sandbars (SABs) are increasingly favored as an efficient method for beach nourishment, helping to mitigate beach erosion and maintain the sediment transport budget, thus promoting ecological stability.

Laboratory Investigation on Hydrodynamic Performance of an Innovative Aeration Device with a Wave-Driven Heaving Buoy

Energies, 2018
Coastal seawater quality is of significance for the environment, ecology and fisheries. In recent years, the hypoxia or anoxia problems of bottom seawater aggravated due mainly to the seawater stratification and eutrophication.

Regular Oscillation Sub-spectrum of Rapidly Rotating Stars

, 2012
We present an asymptotic theory that describes regular frequency spacings of pressure modes in rapidly rotating stars. We use an asymptotic method based on an approximate solution of the pressure wave equation constructed from a stable periodic solution ...

OBLIQUE SHOCK WAVE REFLECTION FROM THE WALL [PDF]

Научно-технический вестник информационных технологий, механики и оптики, 2015
Regular and Mach (irregular) reflection of an oblique shock wave from the wall is considered. Criteria for the transition from regular to irregular reflection are described: von Neumann criterion and the criterion for fixed Mach configuration. Specific

Reflection and transmission of ocean wave spectra by a band of randomly distributed ice floes

, 2014
A new ocean wave/sea-ice interaction model is proposed that simulates how a directional wave spectrum evolves as it travels through an arbitrary finite array of circular ice floes, where wave/ice dynamics are entirely governed by wave scattering effects.
