Kinematics and Dynamics of the Galactic Halo from RR Lyrae Variable Stars

Astronomy Letters, 2018
Based on a sample of RR Lyrae variable stars including more than 9000 objects with proper motions and distances, we have investigated the kinematics of the Galactic halo from the two-dimensional velocity field. We have used both the proper motions deduced independently by us from the positional data taken from all-sky catalogues in a time interval up ...

Kinect-based assessment of lower limb kinematics and dynamic postural control during the star excursion balance test

Gait & Posture, 2017
Assessments using dynamic postural control tests, like the Star Excursion Balance Test (SEBT), in combination with three-dimensional (3D) motion analysis can yield critical information regarding a subject's lower limb movement patterns. 3D analysis can provide a clear understanding of the mechanisms that lead to specific outcome measures on the SEBT ...

Dynamical and kinematical near homoaxial rotations suitable for representation of nonuniformly rotating stars with extended atmospheres

Astrophysics and Space Science, 1985
A nontrivial 'velocity tensor' is suitably defined to represent in the common frame the so-called 'classes of dynamical and kinematical near homoaxial rotations' of a deformable finite material continuum. These classes have simple and interesting physical interpretation, especially for treating of nonuniform rotation and its applications to ...
