In this paper, the skew control of the load (container) in the quay crane used in the dockside of a container terminal is investigated. The mathematical model of the 3-dimensional (3D) motions of the load is first derived. The container hooked to a spreader is suspended by four ropes in air. When the container is accelerated by the trolley or is disturbed by winds, it will make a rotational mot...

In this paper, we investigate the translational and rotational motion of the end-effector of a robot under visual feedback from a Þxed camera. We achieve an exponential stability result for the regulation of the end-effector to a desired location and orientation. SpeciÞcally, by utilizing visual information from one Þxed camera, we capture the motion of 4 points located in a Þctitious plane att...

There is accumulating evidence that the brain's neural coding strategies are constrained by natural stimulus statistics. Here we investigated the statistics of the time varying envelope (i.e. a second-order stimulus attribute that is related to variance) of rotational and translational self-motion signals experienced by human subjects during everyday activities. We found that envelopes can reac...

Rotational motion of heated 72Ge is studied within the microscopic shell-model Monte Carlo approach. We investigate the angular momentum alignment and nuclear pairing correlations associated with J^{π} Cooper pairs as a function of the rotational frequency and temperature. The reentrance of pairing correlations with temperature is predicted at high rotational frequencies. It manifests itself th...

A new nonrigid motion illusion is presented based on patterns of aligned nonparallel line segments undergoing apparent motion. The illusory effect can be explained by the mismatch in local orientation segments that signals local rotational motion contradictory to the global translational motion.

Thrips fly at a chord-based Reynolds number of approximately 10 using bristled rather than solid wings. We tested two dynamically scaled mechanical models of a thrips forewing. In the bristled design, cylindrical rods model the bristles of the forewing; the solid design was identical to the bristled one in shape, but the spaces between the 'bristles' were filled in by membrane. We studied four ...

The method we propose simpli es the practical procedure for hand eye calibration Indeed no more calibration jig is needed and small calibration motions can be used Without calibration jig camera motions are computed up to an unknown scale factor through structure from motion algorithms rather than pose estimation This work was supported by the European Community through the Esprit IV reactive L...

the focus of studies in the field of passive walking has often been on straight walking, while less attention has been paid to the field of turning motions. in this paper, the passive motions of a finite width rimless wheel as the simplest 3d model of passive biped walkers was investigated with a focus on turning motions. for this purpose, the hybrid model of the system consisting of continuous...

The linear Doppler effect has been widely used to detect the translational motion of objects. However, it suffers difficulties in measuring angular a rotating target. In recent years, rotational based on vortex beam helpful solve problem measurement and attracted extensive attention remote sensing. This paper expounds theoretical experimental basis briefly summarizes its development for detecti...

Pure rotational lines are important for monitoring water concentrations in many environments both in space and on earth. A list of line intensities of rotational transitions for H2 O is calculated using variational nuclear-motion wave functions and an ab initio dipole moment surface. This methodology should be equally reliable for both allowed and forbidden rotational transitions. Extensive com...
