Abstract: This paper proposes a novel method for calibrating the relative orientation of a camera fixed on a rotation axis using the constrained global optimization algorithm. Because the camera cannot directly 'see' the rotation axis, the… read more here.

DOI: 10.3389/fphys.2022.833646
Abstract: A long rowing stroke length is crucial for adequate rowing performance. Therefore, the relocation of the oar from traditional “in front” (NORM) to “behind the rotation axis” (GATE) may increase (para) rowing performance. Thus, 15… read more here.
