... reach. Design/methodology/approach The types of motion of this link, i.e. translational, screw motions, combinations thereof, and self‐motions, are first defined and determined, simplifying the understanding of the instantaneous behaviour of the manipulator, aided by the definition of an alternative...

.... The purpose of this paper is to consider the influence of the external waves on oceanic structures. Design/methodology/approach A mathematical model of an ocean environment was constructed, in which wave‐induced flow fields cause structural surge motion, then solutions to the mathematical model were...

...Antonio Munjiza; Mathew Price; Garry Morrison Purpose The purpose of this paper is to present an image based method for estimating the 3D motion of rigid particles from high‐speed video footage (HSV). The computed motion can be used as either a means to generate quantitative feedback for a process...

...@ibnm.uni‐hannover.de © Emerald Group Publishing Limited 2008 Computational geometry Motion Contact detection of moving rigid bodies is an important problem in various fields like discrete element methods (DEMs), computer vision, robotics, etc. When dealing with numerous bodies...

... a complete mesh cycle. Toothed gears/wheels can be classified, for example, according to the position of shafts (spur and bevel gears), to the number of steps (one and multistep gears), to the relative motion of shafts (row and planetary gears), to the position of the teeth on the wheel rim (straight...

.... Consequently, an important direction to extend this work is to consider more general classes of optical flows. Originality/value The main contribution of the present study is the use of multigrid methods and a projection scheme to relate the state equation to the apparent image motion. It should be also...

... nodal values of the gravitational acceleration gˆ _em leads to negligible errors, but to a large reduction of the computational effort. The goal is to simulate the motion of a satellite with a rectangular shape on a circular orbit within the gravitation field of the earth...

... the rotational motion. This factor has commonly been neglected in discrete element modelling although it will significantly influence the dynamic behaviour of non‐spherical particles. In this paper two methods, vector transformation and tensor transformation, for calculation of the rotational motion of particles...
