Rhythmic and monotonously repetitive, but quite unpredictable in its details, the structure of the sea surface is an epitome of the natural world. Surface waves have been studied actively by mathematicians and physicists since the dawn of modern science.

Nature, 1924
IN a letter published in NATURE on August 19, 1920, p. 777, I said that, judging from appearances, wind-formed waves increased in length only when the waves were in a “breaking” condition, and it was suggested that the breaking crests, by imparting their momentum to the upper strata of the water, and so establishing a gradually increasing surface ...

The Physics of Fluids, 1970
A criterion proposed earlier for determining airflow separation from wind waves and a previously determined relationship between surface roughness and wind stress are herein correlated. The results indicate that the airflow boundary layer is developed due to the form drag provided by wavelets (surface roughness) superimposed on big waves.

The most apparent and usually the most important waves in the spectrum of waves at sea (see Figure 5.2) are those generated by the wind. Wind-generated waves are much more complex than the simple monochromatic waves considered to this point. We must briefly look into how these waves are generated by the wind and some of the important characteristics ...

Balanced fractional-slot wave windings
Electrical Engineering, 1948The a-c wave windings which are used mostly in rotors of induction motors are “modified” d-c wave windings whose winding pitch is changed after each p winding elements (p = number of pole pairs). These modified wave windings are balanced, but they can be applied to integral-slot and (integral+1/2)-slot windings only.
