Spin Rate Measurements in Cricket Bowling Using Magnetometers
Proceedings, 2020 The ability to measure and classify spin has been of great interest to cricket organizations, coaches, and athletes. While video is common, an alternative approach is to use 3D motion capture analysis with reflective spheres, which changes the ...

Spin Rate and Deflection Ratio of a Ping Pong Ball [PDF]
International Scholastic Journal of Science, 2013 To investigate the effects of a spherical object’s spin rate on the curvature of its flight, Ping Pong balls, of varying spin rates, were hit horizontally and recorded from above with a high-speed camera.

Spin rate distribution of small asteroids [PDF]
Icarus, 2008 Abstract The spin rate distribution of main belt/Mars crossing (MB/MC) asteroids with diameters 3–15 km is uniform in the range from f = 1 to 9.5 d−1, and there is an excess of slow rotators with f 1 d−1. The observed distribution appears to be controlled by the Yarkovsky–O'Keefe–Radzievskii–Paddack (YORP) effect.

Spin Rate of a Racquetball Due To AngularImpact
International Scholastic Journal of Science, 2015 The relationship between the impact angle of a racquetball and the resulting angular velocity of the ball was investigated. Impact angles ranging from 0° to 80° were tested.

Effect of spin labelling on the aggregation kinetics of yeast prion protein Ure2 [PDF]
Royal Society Open Science, 2021 Amyloid formation is involved in a wide range of neurodegenerative diseases including Alzheimer's and prion diseases. Structural understanding of the amyloid is critical to delineate the mechanism of aggregation and its pathological spreading.

Membranes, 2022 The spin-lattice relaxation rate (T1−1) of lipid spin labels obtained from saturation recovery EPR measurements in deoxygenated membranes depends primarily on the rate of the rotational diffusion of the nitroxide moiety within the lipid bilayer. It has been shown that T1−1 also can be used as a qualitative convenient measure of membrane fluidity that ...

Measurement of Flight Dynamics of a Frisbee Using a Triaxial MEMS Gyroscope
Proceedings, 2020 A Frisbee with a mass of 0.21 kg, diameter of 0.27 m and moment of inertia (MOI) of 0.002 kg·m2 was instrumented with a triaxial gyroscope. The Frisbee was thrown at low angular velocities as the measurement limit of a single gyroscope was at 6.065 rps ...

Bowling Performance Assessed with a Smart Cricket Ball: A Novel Way of Profiling Bowlers
Proceedings, 2020 Profiling of spin bowlers is currently based on the assessment of translational velocity and spin rate (angular velocity). If two spin bowlers impart the same spin rate on the ball, but bowler A generates more spin rate than bowler B, then bowler A has a

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma
Journal of High Energy Physics, 2022 We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant g. The spin relaxation rate Γ s in spin hydrodynamics is shown to be Γ s ~ g 4 log(1/g)T(T/M)2 in the heavy ...
