A common problem in physics and engineering is determination of the orientation of an object given its angular velocity. When the direction of the angular velocity changes in time, this is a nontrivial problem involving coupled differential equations. Several possible approaches are examined, along ...
Exciting evidence compatible with such CAN models was recently provided by investigations of the Drosophila melanogaster central complex, where head direction cells whose activity was modulated by angular velocity were shown to be organised in a ring according to their preferred direction34,35. It is,...
Next, we studied how the angle of the speed with the direction to the ball is related to the distance to the ball and the game phases. We observed that, during the defensive phase, goalkeepers are the players that run more parallel to the ball, while forwards are the ones running more...
If you know that a particle is moving in a circular path with a velocityvat a distancerfrom the center of the circle, with the direction ofvalways being perpendicular to the radius of the circle, then the average angular velocity can be written as: ω=Δvr where angular velocity **ω**...
Modeling a Thrust Vector Controlled Rocket in Simulink Thrust Vectoring or Thrust Vector control is the ability of an aircraft or a rocket's propulsion system to manipulate the direction of its thrust to control the rocket or aircrafts attitude or angular velocity. Adjusting the gimbal angle, contr...
However, rotation causes the wake to be deflected in the direction of tangential velocity and shear layers to shrink. In addition, as the symmetry is broken by rotation, shear layers have different Acknowledgments This work has been financially supported by the “Ministerio de Economía y ...

At this point the direction of rotation changes to clockwise (negative) rotation until it reaches a minimum at 124 hours of \(-18.4\pm 8.3^{\circ }\) (a total of \(52.4\pm 10.2^{\circ }\) clockwise rotation). After this, there is a mixture of anti-clockwise and clockwise rotation...
It is demonstrated that the 3-vector $$\varvec{S}$$ currently associated to the spin in an inertial frame does not contract, but rather dilates, in the direction of the velocity. The correct vector $$\varvec{T}$$ is individuated. The equation of motion f
1a. However, few studies are based on a nacelle pressure relief process under a horizontal opening mode in which the PRD hinge is oriented parallel to the freestream direction, as shown in Fig. 1b. Moreover, because the structure of the PRD and the working conditions of the pressure ...
