DOI: 10.1007/s00034-017-0647-x
Abstract: Polarization of tri-axial signals is defined using instantaneous rotational characteristics of the three-dimensional (3D) trajectory. We propose a rotational model to parameterize the time evolution of the 3D trajectory as a sequence of scaled rotations.… read more here.

DOI: 10.1016/j.applanim.2021.105296
Abstract: Abstract Identifying and monitoring parturition of individual animals may help producers increase attentiveness, enabling early detection of dystocia during parturition. Parturition events are marked by subtle behavioral changes often difficult to detect by observation alone.… read more here.
