TLDR
New methods in experimental fluid mechanics provide insights into the physiological mechanisms of aquatic force generation and limits to locomotor performance.Abstract:
Understanding how fishes generate external fluid force to swim steadily and maneuver has proven to be difficult because water does not provide a stable platform for force measurement. But new methods in experimental fluid mechanics provide insights into the physiological mechanisms of aquatic force generation and limits to locomotor performance.read more

Passive and Active Flow Control by Swimming Fishes and Mammals
Frank E. Fish,George V. Lauder +1 more
TL;DR: The vortex wake shed by the tail differs between eel-like fishes and fishes with a discrete narrowing of the body in front of the tail, and three-dimensional effects may play a major role in determining wake structure in most fishes.
Journal ArticleDOI
A review of fish swimming mechanics and behaviour in altered flows
TL;DR: New data are presented here which show that behaviour changes in altered flows when either the lateral line or vision is blocked, showing that fish rely on multi-modal sensory inputs to negotiate complex flow environments.

Mechanics and control of swimming: a review
J.E. Colgate,Kevin M. Lynch +1 more
TL;DR: In this paper, the authors review clues to artificial swimmer design taken from fish physiology and formalize and review the control problems that must be solved by a robot fish, and exploit fish locomotion principles to address the truly difficult control challenges of station keeping under large perturbations.

The hydrodynamics of eel swimming: I. Wake structure
Eric D. Tytell,George V. Lauder +1 more
TL;DR: The hydrodynamics of American eels swimming steadily at 1.4 L s-1 are examined and it is inferred that the lack of downstream flow results from a spatial and temporal balance of momentum removal and thrust generated along the body, due to the relatively uniform shape of eels.

Undulatory swimming in sand: subsurface locomotion of the sandfish lizard.
TL;DR: To predict sandfish swimming speed, an empirical model is developed by measuring granular drag force on a small cylinder oriented at different angles relative to the displacement direction and summing these forces over the animal movement profile, which implies that the noninertial swimming occurs in a frictional fluid.

Animal Physiology: Adaptation and Environment
TL;DR: In this article, the authors present an overview of the physiological properties of the human body, including Oxygen, Respiration, Food and Energy, Water and osmotic regulation, control and integration, and Hormone control.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.

Animal Physiology: Adaptation and Environment
TL;DR: The treatment of benign ulcer disease with X-irradiation is certainly controversial and has not been widely accepted for general use in most medical centers.
Book
Neural Control of Rhythmic Movements in Vertebrates
TL;DR: The chapters which present theoretical perspectives, mathematical analyses or modelling of central pattern generators to a considerable degree draw upon material presented in experimental chapters, and every attempt is made to make the discussion easily accessible to the non-mathematical reader.
Journal ArticleDOI
Force platforms as ergometers
TL;DR: Walking and running on the level involves external mechanical work, even when speed averaged over a complete stride remains constant, which must be performed by the muscles to accelerate and/or raise the center of mass of the body during parts of the stride.
