Heteroclinic optimal control solutions for attitude motion planning

, 2013
An analytical attitude motion planning method is presented that exploits the heteroclinic connections of an optimal kinematic control problem. This class of motion, of hyperbolic type, supply a special case of analytically defined rotations that can be ...

Geodesic complexity and motion planning on graphs

, 2021
The topological complexity TC(X) of a space X was introduced in 2003 by Farber to measure the instability of robot motion planning in X. The motion is not required to be along shortest paths in that setting.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

LocalPoly interpolation: Generalizing tricubic for Cn continuity in M‐dimensional spaces

Engineering Reports
Tricubic interpolation, originally introduced by Lekien and Marsden (Int J Numer Methods Eng. 2005; 63(3): 455–471), has been a cornerstone in the field of interpolation, providing C1 continuous interpolations within three‐dimensional spaces.
