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.

Let S be a skewfield. If J and / ' are submodules of 2 such that the nonzero elements of J are the inverse elements of those of J , then J and J' form a "pair of inverse modules." A module admitting an inverse module will be called a /-module and a selfinverse module containing 1 will be called an 5-module. In an earlier paper the author has shown that if S is a (commutative) field of character...

–In virtual human modeling, the shoulder is usually composed of clavicular, scapular and arm segments related by rotational joints. Although the model is improved, the realistic animation of the shoulder is hardly achieved. This is due to the fact that it is difficult to coordinate the simultaneous motion of the shoulder components in a consistent way. Also, the common use of independent 1-DOF ...

In this paper, we present SimHuman, a platform for the generation of real-time 3D environments with virtual agents. SimHuman is highly dynamic and configurable, as it is not based on fixed scenes and models, and has an embedded physically based modelling engine. Its agents can use features such as path finding, inverse kinematics and planning to achieve their goals. The paper explains in detail...

Background: Depression, as the second leading cause of dysfunction, is one of the most common mental health disorders. Given that micronutrients have always played a significant role in all physical and psychological aspects of individuals. This study was conducted to investigate the relationship of dietary intake of Selenium, Magnesium, Zinc, and anthropometric profiles with depression in fema...
