Motion control study on goat-like three segmented mechanical leg
- Engineering2016 IEEE International Conference on Information and Automation (ICIA)
Based on a structure of goat's hindlimb, the work aims at studying the movement mechanism to remove redundant degrees of freedom in three segmented leg by analyzing parameters of joints, toes and the centroid trajectory of the leg.
Mandibular biomechanics as a key factor to understand diet in mammals
Feed biomechanics represents the set of analyses performed to relate variation in feeding system morphology to variation in how animals feed (feeding behavior) and what they feed on (diet) and reinforces the idea that food is processed differently depending on mandibular morphology.
Synthesizing walking motions independent of limb length
- Computer Science
A method to change the leg length of a character during an animation while preserving the motion capture data and without leaving visual artifacts is presented, which results in a system capable of following a given path on a 2D plane in a 3D environment using a motion graph as input, while the legs of the character change.
Crossing regimes of temperature dependence in animal movement.
- Environmental ScienceGlobal change biology
A biomechanical approach, the Metabolic Theory of Ecology and empirical data are merged to show that animal movement displays multiple regimes of temperature dependence and that crossing these regimes has important consequences for population dynamics and stability, which depend on the parameters controlling predator-prey interactions.

This treatise is intended to serve as a monograph on the history of computer programming and its applications to the field of computer graphics.
Investigation of an Articulated Spine in a Quadruped Robotic System
An efficient, high-speed quadruped robot is useful in applic ations spanning the service and entertainment industries. The military is also keenly inte rested in this platform as legged, robotic…
Rowing propulsive mechanism based on rower biomechanics and blade hydrodynamics
Rower biomechanics, stroke style, and hydrodynamic of the blade are among the important factors which influence rowing performance. Deeper understanding of these aspects will help the rower and…
A Paleopathological Analysis to Identify Possible Adult Flexible Pes Planus from Pedal Bones
The results indicate that the width of the calcaneus has more influence on the medial longitudinal arch collapse than previously argued and the angular shape of the talus head on the transverse plane correlated with some of the angles used in diagnosing pes planus clinically.
Three-dimensional monitoring of weightlifting for computer assisted training
This paper investigates the use of 3D information in the context of sports training by detecting, collecting and extracting every useful data which give insight about the body technique during the weightlifting attempt and making all the necessary calculations.
Agent tracking: a psycho-historical theory of the identification of living and social agents
- Psychology, PhilosophyBiology & philosophy
This theory investigates how the tracking processes that humans use for identifying agents interact with the unique socio-historical contexts that support agent-identification practices, and can generate novel hypotheses regarding the distinction between recognition-based, heuristic- based, and explanation-based agent-Identification.

The peculiarities of the coronary circulation are quite sufficient to explain the phenomenon without the introduction of so unnecessary a theory as that of Dr. Pettigrew, and the injection of fluid into the coronary vessels causes the whole heart to open up from the congestion of the ventricular walls.
Locomotion of animals
This book is about how animals travel around on land, in water and in the air. It is mainly about mechanisms of locomotion, their limitations and their energy requirements. There is some information…
Partitioning the Energetics of Walking and Running: Swinging the Limbs Is Expensive
- Engineering, BiologyScience
It is estimated that swinging the limbs requires an appreciable fraction of the energy used during terrestrial legged locomotion, contrary to some previous suggestions.
Gait and the energetics of locomotion in horses
- Biology, EngineeringNature
It is confirmed that the natural gait at any speed indeed entails the smallest possible energy expenditure, and rates of oxygen consumption as an indicator of rates of energy consumption are used.
Optimum take-off techniques for high and long jumps.
- EducationPhilosophical transactions of the Royal Society of London. Series B, Biological sciences
A simple model, which takes into account the mechanical properties of muscle, predicts optimum take-off techniques that agree well with those used by athletes and are remarkably insensitive to the numerical values assigned to the physiological parameters.
Evidence for an elastic projection mechanism in the chameleon tongue.
- EngineeringProceedings. Biological sciences
To capture prey, chameleons ballistically project their tongues as far as 1.5 body lengths with accelerations of up to 500 m s(-2). At the core of a chameleon's tongue is a cylindrical tongue…
Evolution of Levers and Linkages in the Feeding Mechanisms of Fishes1
- BiologyIntegrative and comparative biology
This study examines the diversity of mechanical design of the oral jaws in 35 species of ray-finned fishes to analyze lower jaw lever models in a broad phylogenetic range of taxa and identify the origin and evolutionary patterns of change in the linkage systems that power maxillary rotation and upper jaw protrusion.

Cranial mechanics and feeding in Tyrannosaurus rex
- Environmental ScienceProceedings of the Royal Society of London. Series B: Biological Sciences
Finite–element–generated stress–strain patterns are consistent with T. rex cranial morphology: the maxilla–jugal suture provides a tensile shock– absorption function that reduces localized tension yet ‘weakens’ the skull overall.
