The study proposes an inversion method applicable to observations of deglacial land uplift and tilt near the margin of a major Pleistocene ice-sheet. This information allows the determination of the cross-section of the ice-sheet and the calculation of the thickness of the lithosphere. The method is applied to the Pleistocene glaciations in Fennoscandia and Laurentia and yields similar lithosph...

given by (6) can successfully shorten the settling time of h e tracking control at different operation speeds. In our experimental setup the settling time is in the range of 0.50 N 0.65 s for the conveyor belt running between 9.43 N 26.60 c d s . As we have seen, this is a great improvement in the tracking control compared with that where no special care is taken to compensate for the feedback ...

We attach the degenerate signature (n,0,1) to the dual Grassmann algebra of projective space to obtain a real Clifford algebra which provides a powerful, efficient model for euclidean geometry. We avoid problems with the degenerate metric by constructing an algebra isomorphism between the Grassmann algebra and its dual that yields non-metric meet and join operators. We focus on the cases of n=2...

In this paper we address the problem of creating accurate joint models from real motions while allowing scalability. We propose an automatic method to model, scale and simulate non-idealized joints from the external motion of markers. We demonstrate the method on the human knee joint modeling for musculoskeletal analysis and for character animation. The resulting joints, called correlative join...

This study provides insight into the ways computers and technology can help athletes and instructors improve performance by capturing 3D information about human skeletal kinematics during physical activity. We explore current methods being applied and look at possible technological improvements for the future.
