Spinning gyroscope in an acoustic black hole: precession effects and observational aspects
European Physical Journal C: Particles and Fields, 2020 The exact precession frequency of a freely-precessing test gyroscope is derived for a $$2+1$$ 2+1 dimensional rotating acoustic black hole analogue spacetime, without making the somewhat unrealistic assumption that the gyroscope is static.

Assessment and Measurement of the Side-Effects of an Evidence-Based Intervention with an Advanced Smart Cricket Ball Exemplified by a Case Report on Correcting Illegal Bowling Action [PDF]
SensorsCorrecting an illegal bowling action in cricket through technical intervention involves modifying a movement pattern. This study evaluated the success of an intervention aimed at correcting the suspect actions of two off-spin bowlers and assessed whether

Laser Backscattering Analytical Model of Doppler Power Spectra about Convex Quadric Bodies of Revolution during Precession [PDF]
Remote SensingIn the realm of ballistic target analysis, micro-motion attributes, such as warhead precession, nutation, and decoy oscillations, play a pivotal role. This paper addresses these critical aspects by introducing an advanced analytical model for assessing ...

Misaligned spin and orbital axes cause the anomalous precession of DI Herculis
Nature, 2009 The orbits of binary stars precess as a result of general relativistic effects, forces arising from the asphericity of the stars, and forces from additional stars or planets in the system.

Experimental model for the description of the behaviour of a 9-mm projectile at a target
Forensic Sciences Research, 2021 Analysis of crime scenes involving single-fire-gun projectiles requires the determination of the direction of arrival of a projectile at the target and other factors to reconstruct events.

Analyzing the Motion of Symmetric Tops Without Recurring to Analytical Mechanics
Frontiers in Physics, 2020 Characterizing the dynamics of heavy symmetric tops is essential in several fields of theoretical and applied physics. Accordingly, a series of approaches have been developed to describe their motion.
