Optimizing snake locomotion in the plane. II. Large transverse friction
Silas Alben
We determine analytically the form of optimal snake locomotion when the coefficient of transverse friction is large, the typical regime for biological and robotic snakes. We find t…
Optimizing snake locomotion in the plane. I. Computations
Silas Alben
We develop a numerical scheme to determine which planar snake motions are optimal for locomotory efficiency, across a wide range of frictional parameter space. For a large coeffici…
Color scales that are effective in both color and grayscale
Silas Alben
We consider the problem of finding a color scale which performs well when converted to a grayscale. We assume that each color is converted to a shade of gray with the same intensit…
Falling Flexible Sheets
Silas Alben
We present a fluid dynamics video showing simulations of flexible bodies falling in an inviscid fluid. Vortex sheets are shed from the trailing edges of the bodies according to the…
Inviscid Simulations of Interacting Flags and Falling Sheets
Silas Alben
We present a fluid dynamics video showing simulations of flexible bodies flapping and falling in an inviscid fluid. Vortex sheets are shed from the trailing edges of the bodies acc…
