Oceanic Double-diffusion: Introduction

Vertical Structure and Double Diffusion Convection of the Water Column in the Southern Shores of the Caspian Sea

Background and Objectives: Different types of instability occur at sea. Layered structures are one of the most important physical phenomena in marine environments. Static stability and double diffusion are associated with density changes with respect to depth and temperature and salinity gradients, respectively. Due to the difference in temperature and salinity in the water column, marine areas...

Acoustic scattering from double-diffusive microstructure.

Laboratory measurements of high-frequency broadband acoustic backscattering (200-600 kHz) from the diffusive regime of double-diffusive microstructure have been performed. This type of microstructure, which was characterized using direct microstructure and optical shadowgraph techniques, is identified by sharp density and sound speed interfaces separating well-mixed layers. Vertical acoustic ba...

Fundamental Solution in the Theory of Thermoelastic Diffusion Materials with Double Porosity

The main purpose of present article is to find the fundamental solution of partial differential equations in the generalized theory of thermoelastic diffusion materials with double porosity in case of steady oscillations in terms of elementary functions.

Closed formulas for the price and sensitivities of European options under a double exponential jump diffusion model

We derive closed formulas for the prices of European options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by S. Kou in 2002. This author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...
