The Integration of Angular Velocity

Angular velocity integration in a fly heading circuit

Many animals maintain an internal representation of their heading as they move through their surroundings. Such a compass representation was recently discovered in a neural population in the Drosophila melanogaster central complex, a brain region implicated in spatial navigation. Here, we use two-photon calcium imaging and electrophysiology in head-fixed walking flies to identify a different ne...

Numerical study on the jet dynamic through centrifuge spinning: influence of angular velocity

Integrating rotation from angular velocity

The integration of the rotation from a given angular velocity is often required in practice. The present paper explores how the choice of the parametrization of rotation, when employed in conjuction with different numerical time-integration schemes, effects the accuracy and the computational efficiency. Three rotation parametrizations – the rotational vector, the Argyris tangential vector and t...

Comparison of the Maximum Angular Velocity of Lower Limb Joints in Different Methods of Zenkotsu Dachi in Karate

Objective: The proper implementation of Dachi in karate as a basic technique has a direct impact on the implementation of other techniques. Therefore, the aim of the present study was to compare the maximal angular velocity of hip, knee and ankle joints in differen  Zenkotsu dachi techniques in karate. Methods: 12 male karate athletes (Height 175 ± 5, mass 75 ± 5, Age 25 ± 5, Background 8 ± 2)...

The Angular Velocity of the Apsidal Rotation in Binary Stars

The shape of a rotating star consisting of equilibrium plasma is considered. The velocity of apsidal rotation of close binary stars (pe-riastron rotation) which depends on the star shapes is calculated. The obtained estimations are in a good agreement with the observation data of the apsidal motion in binary systems.
