This paper discusses the problem of improving the realism of motion not only from the joint point-of-view as for robots, but also in relation to the deformations of bodies, hands and faces during animation. The mapping of surfaces onto the skeleton may be based on the concept of Joint-dependent Local Deformation (JLD) operators, which are specific local deformation operators depending on the na...

for the past 3 decades, creating industrial clusters have been considered as an approach for the development of most small and medium enterprises. the goal of this programme is that all small and medium enterprises locating in a certain geoghraphic area can concentrate on cluster approach to collaborate in market research, production design, training and other activities that are not economical...

The chair of Operating Systems of Chemnitz University of Technology participated in a joint project “Knowledge Workshop Computing Systems”. As a result, twelve universities across Germany created a total of 145 e-learning modules for the subject of Technical Computer Science. Experiences from this project – in terms of creation of modules based on XML as well as from use in presence teaching at...

In this paper, a new inverse kinematics (IK) solver is introduced which can solve a multiple constrained 12-DOF human limb analytically with the joint limits taken into account. By combining the IK solver with multilevel curve fitting technique, we enable the user to specify constrains on few keyframes through a mouse or keyboard, then the joint angles of the figure at each keyframe are automat...

The purpose of this paper is to develop a method of Collision-Free Path Planning (CFPP) for articulated robots. First, the configuration of a robot is designed using a set of robot joint angles derived from robot inverse kinematics. The joint space, which is made of a joint angle set, forms a Configuration space (Cspace). Obstacles in a robot work-cell are transformed into Cobstacles (obstacles...

Friction stir welding (FSW) is an emerging manufacturing technology for aerospace structures. It will see widespread use in the future as it offers ways of creating lighter structures at lower manufacturing cost than traditional methods (riveting, adhesive bonding). Since its invention in 1991, FSW has known fast improvements and many studies have demonstrated its capability for joining a wide ...

The genome of herpes simplex virus type-1 undergoes a high frequency of homologous recombination in the absence of a virus-encoded RecA-type protein. We hypothesized that viral homologous recombination is mediated by the combined action of the viral single strand DNA-binding protein (ICP8) and helicase-primase. Our results show that ICP8 catalyzes the formation of recombination intermediates (j...
