In this paper it is explained how most of asteroids can avoid very close approach to Jupiter, to the earth for earth orbit crossing asteroids, and to Neptune for Kuiper-belt asteroids by mechanisms which work also for Neptune-Pluto system. In fact the mutual distance of the planets cannot become very small as the critical argument librates around 180 0 because of 2:3 mean motion resonance and t...

Axial equiform Bricard motions are equiform motions where each point of the moving system sticks to a sphere and additionally a line (the axis) is fixed throughout the motion. In this paper we show that there are only two types of such motions. The first one is determined by requiring that the axis is translated along itself and another line, which is skew to the axis, always contains a point o...

The notion of transplanting limbs to enhance a motion capture database is appealing and has been recently introduced [Sha04], [Ike04]. A key difficulty in the process is identifying believable combinations. Not all transplantations are successful; we also need to identify appropriate frames in the different clips that are “cutpasted.” In this paper, we describe motion grafting, a method to synt...

This study aims to develop ranking systems for evaluation of the stressfulness of joints and joint motions based on perceived discomforts measured through an experiment. Twenty healthy male subjects participated in the experiment, where discomforts for varying joint motions in the sitting and standing postures were measured using the magnitude estimation. The results showed that the perceived d...

This paper presents a novel method for generating balancing character poses by means of a weighted inverse kinematic constraint algorithm. The weighted constraints enable us to control the order of priority so that more important conditions such as balancing can take priority over less important ones. Maintaining a balancing pose enables us to create a variety of physically accurate motions (e....

We define motion polynomials as polynomials with coefficients in the dual quaternions and study their factorizations. The motion polynomials correspond to motions in 3D space, and factoring into linear factors means to compose the motion into translations and rotations. This allows to realize the motion by a linkage with revolute or prismatic joints. This is joint work with G. Hegedüs (Univ. Ob...
