The Asteroid Photometric Catalogue was used to redetermine the rotation periods of all asteroids with data in the catalogue. The quality of the period determinations was divided into five groups. The total number of asteroids studied were 710 and 225 of these were considered not to be observed enough to yield any rotation period (code 0).

Strain Rates and Material Spins
Journal of Elasticity, 1998This work presents a thorough discussion concerning the definition and properties of various material time rates of Lagrangian strain measures, objective corotational rates of Eulerian strain measures, and related spin tensors needed in the formulation of sophisticated constitutive equations of continuum physics (anelasticity, rheological laws ...

and spin–spin relaxation rates in CuV2S4
Physica B: Condensed Matter, 1999Abstract 63 Cu and 51 V spin–spin relaxation rates have been measured in CuV2S4 which reveals CDW transition. 63 Cu spin echo decays as Gaussian while 51 V spin echo does as Lorentzian. Both 63 Cu and 51 V spin–spin relaxation rates show remarkable changes due to CDW transition.

Ball spin in the tennis serve: spin rate and axis of rotation
Sports Biomechanics, 2013The purpose of this study was to describe three-dimensional ball kinematics including spin axis and spin rate for the flat, slice, and kick serves executed by elite male tennis players. Trajectories of three retro-reflective markers attached to the surface of the ball were measured using a Vicon MX motion analysis system. The local coordinate system of

The rate of spreading in spin coating
Journal of Fluid Mechanics, 2000In this paper we reconsider the fundamental problem of the centrifugally driven spreading of a thin drop of Newtonian fluid on a uniform solid substrate rotating with constant angular speed when surface-tension and moving-contact-line effects are significant.

This paper presents the analysis and design of the spin rate control flight algorithm for the dual-spin Galileo spacecraft. Because of thruster plume contamination constraints, only one poorly located thruster is available for spin rate correction in each spin direction.
