Similarity relations of wind waves in finite depth
… the rear face of a growing wind-sea spectrum in finite depth based on Phillips (1958), Toba (1972) and Donelan et al. (1985) are tested using spectral measurements from Lake St. Clair. Assuming spectral similarity in wave number space relations between the energy, equilibrium parameters and peak …

Wave-current interaction in water of finite depth
… interaction of waves and current in water of finite depth is studied. Wind is not included. In the first part, a 2D theory for the wave effect on a turbulent current over rough or smooth bottom is presented. The logarithmic profile of the basic current is modified by the waves due to an …

A strip theory approximation for wave forces on submerged vehicles in finite depth water
Autonomous Underwater Vehicles (AUV's) are becoming of increasing use in shallow waters for oceanographic data collection, coastal mapping, and military operations such as mine surveillance along enemy coastlines. Currently the control of AUV's in shallow water is very limited, largely due to a …

Planar algebras: A category theoretic point of view
… of a planar algebra and prove some finiteness results for the affine representations of finite depth planar algebras. We also show that the radius of convergence of the dimension of an affine representation of the planar algebra associated to a finite depth subfactor is at least as …

A characterization of internal solitons in the SWARM region of the New York bight
… cm/s with a heading of 280 ± 31° T. Two-layer finite-depth theory was tested on this data and shown to consistently overpredict the phase speed of the internal solitons within each group. Predictions of horizontal scale, particle velocities, and displacements were in qualitative agreement with …

Parameterization of convection in a rotating stratified ocean : comparison of numerical and laboratory experiments with theory
… of convection in a rotating stratified ocean of finite depth. Convection is induced from the surface by extracting buoyancy over a circular area. The external parameters are buoyancy forcing of strength Bo applied over a circular area of radius Rs, the rotation rate is measured by f, ambient …

On Steady Water Waves and Their Properties
… then it vanishes as one approaches great depths. Paper II: Linear water waves with vorticity: rotational features and particle paths. Steady linear gravity waves of small amplitude travelling on a current of constant vorticity are found. For negative vorticity we show the appearance of …

Almost well-posedness of the full water wave equation on the finite stripe domain
… a rigorous study of surface waves on water of finite depth subjected to gravitational force. As for `water', it is an inviscid and incompressible fluid of constant density and the flow is irrotational. The fluid is bounded above by a free surface separating the fluid from the air above (assumed …

An experimental study of the spread of buoyant water into a rotating environment
… We focus in particular on the role that finite potential vorticity and background turbulence play in determining the flow properties. When water of an anomalous density enters into an oceanic basin, gravity-driven surface flows can be established as a result of the density difference. …

On the reduction of metal oxides in non-equilibrium hydrogen plasmas
… experimental results indicate the existence of a finite depth-of-reaction in samples exposed to atomic hydrogen; i.e., only a thin surface region is affected by the hydrogen radicals. An analytical model is developed describing the evolution of this depth-of-reaction and its dependence on the …

A Spatial Dynamic Approach to Three-Dimensional Gravity-Capillary Water Waves
… gravity-capillary steady waves on water of finite-depth, which are uniformly translating in a horizontal propagation direction and periodic in a transverse direction, are considered. The exact Euler equations are formulated as a spatial dynamic system in which the variable used for the …

Sill Overflow Processes in the Philippine Archipelago
… Profiler (ADCP), Conductivity, Temperature, Depth (CTD), and lowered ADCP (LADCP) data are used to study the currents and stratification at Panay Sill, at the southern end of Mindoro Strait. We observe a strong bottom-intensified overflow; temporal mean velocity is greater than 0.75 m/s at 50 …

Excitation, Interaction, and Scattering of Localized and Propagating Surface Polaritons

Thin metallic films deposited on glass offer two different SPP waveguide modes, each of which can be addressed preferentially by a proper choice of the …
