PIV-based investigations of animal flight
Experiments in Fluids, 2009An overview is presented of the principles of estimation of fluid forces exerted upon solid bodies, based upon whole-field velocity measurements such as provided by PIV. The focus will be on the range of length and velocity scales characterised by the flight of large insects, birds, bats and small unmanned air vehicles, so that while viscous terms in ...

On numerical modeling of animal swimming and flight
Computational Mechanics, 2013Aquatic and aerial animals have developed their superior and complete mechanisms of swimming and flight. These mechanisms bring excellent locomotion performances to natural creatures, including high efficiency, long endurance ability, high maneuverability and low noise, and can potentially provide inspiration for the design of the man-made vehicles. As

Flight-induced compass representation in the monarch butterfly heading network.
Current Biology, 2021For navigation, animals use a robust internal compass. Compass navigation is crucial for long-distance migrating animals like monarch butterflies, which use the sun to navigate over 4,000 km to their overwintering sites every fall. Sun-compass neurons of

Photographs of animals in flight
2017This chapter will deal with several important aspects that need to be considered when creating exciting and insightful visual material. Photographs of flight are usually “action photographs” that require quick reaction. The wings of insects move so rapidly that they can only be “frozen” over fractions of milliseconds.

Metabolic changes in the animals subjected to space flight
Acta Astronautica, 1982The activity of the enzymes involved in aminoacid metabolism (tyrosine aminotransferase, TAT, tryptophan pyrrolase TP, serine dehydratase, SD) with rapid response to glucocorticoids and enzymes requiring for activity increase repeated administration of corticosterone (alanine aminotransferase, ALT, aspartate aminotransferase, AST) in liver, the changes

Hybrid animation production and the dream of flight
SIGGRAPH ASIA Art Gallery/Art Papers, 2019Through a detailed account of a recent practice-based research project - a short animation project called Jasper, this paper explores how a hybrid analogue/digital production approach can generate a unique and engaging visual style - one that sits between the tangible, handcrafted feel of miniatures and the cleanness, fluidity and flexibility of ...

Animal Flight Mechanics in Physically Variable Gas Mixtures
Journal of Experimental Biology, 1996ABSTRACT Empirical studies of animal flight performance have generally been implemented within the contemporary atmosphere. Experimental alteration of the physical composition of gas mixtures, however, permits construction of novel flight media and the non-invasive manipulation of flight biomechanics.
