Lee Waves and Mountain Waves ∗

Buoyancy perturbations develop when stably stratified air ascends a mountain barrier. These perturbations often trigger disturbances that propagate away from the mountain as gravity (or buoyancy) waves. Gravity waves triggered by the flow over a mountain are referred to as mountain waves or lee waves. Mountain waves sometimes reveal their presence through dramatic cloud formations, such as smoo...

Traveling Waves and Power Waves

M icrowave equivalent-circuit theory is like a grand old building: elegant, carefully crafted, passed from generation to generation, and rooted in history. Traveling waves, the measureable electromagnetic field solutions of Maxwell’s equations in a transmission line, form the foundation of the theory. You must descend into the basement to see them; not many people do so. It is in this “basement...

R waves interrupting T waves.

In the course of some experiments on anesthetized dogs and cats concerned with the production experimentally of ventricular flutter and ventricular fibrillation, Fastier and Smirk (1948) noted that R waves sometimes appeared on the descent of the antecedent T waves, shortly before the onset of veittricular flutter. The flutter was induced by a substance amarin * which had been found by one of u...

Determination of sediments diameter using acoustic waves

The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...

Numerical Calculations of Ship Induced Waves

Nowadays, various numerical methods are developed to extend computational fluid dynamics in engineering applications. One of the most useful methods in free surface modeling is Boundary Element Method (BEM). BEM is used to model inviscid fluid flow such as flow around ships. BEM solutions employ surface mesh at all of the boundaries. In order to model the linear free surface, BEM can be modifie...
