Animals that glide produce aerodynamic forces that enable transit through the air in both
arboreal and aquatic environments. The relative ease of gliding compared with flapping …

Schooling, an archetype of collective behaviour, emerges from the interactions of fish
responding to sensory information mediated by their aqueous environment. A fundamental …

Controlled gliding is one of the most energetically efficient modes of transportation for
natural and human powered fliers. Here we demonstrate that gliding and landing strategies …

This paper derives provably optimal control trajectories for the Li-ion battery fast charging
problem. Conventionally, battery charging protocols must satisfy safety constraints while …

The free fall of heavy bodies in a viscous fluid medium is a problem of interest to many
engineering and scientific disciplines, including the study of unpowered flight and seed …

Falling leaves flutter from side to side due to passive and intrinsic fluid-body coupling.
Exploiting the dynamics of passive fluttering could lead to fresh perspectives for the …

When a coin falls in water, its trajectory is one of four types, determined by its dimensionless
moment of inertia:(A) steady;(B) fluttering;(C) chaotic; or (D) tumbling. The dynamics induced …

Results are reviewed concerning the planar problem of a plate falling in a resisting medium
studied with models based on ordinary differential equations for a small number of …

Falling paper flutters and tumbles through air, whereas a paper airplane glides smoothly if
its leading edge is appropriately weighted. We investigate this transformation from 'plain …

A homogeneous thin plate often flutters while falling through a fluid under gravity. The center
of gravity of the plate moves back-and-forth horizontally and the plate tilting angle oscillates …
