This thesis presents a research on the foundation of the "Tenth five-year" National Science and Technology Project—Research on Internet-based NC (numeric control) Machine Tools Form Design and Humanized Interface Technologies and Implementations Based on the Knowledge of Design an Knowledge of User. It focuses on the human posture and the human modeling of the Ergonomics of the NC machine tools and the frameworks in ICAID system.
At first, hand's grasp trajectory is utilized to detect collisions between a dexterous hand and virtual objects and then the corresponding grasp posture is estimated through measuring fingers' automatic contact conditions.
Second, for removing the influence, we develop the least squares method based on thestereographic projection implemented on a three-dimensional plane. It is described bythe expressions:(4.35挆4.39). This method resolves some problem in Multi-sensoralignment on the same platform when the attitude errors are relatively small.
The Artificial Livestock has 12 degrees of freedom, using slide-follower mechanisms as its joints and servo-motors as power sources of the joints. The feeling system consists of sensors responding to body attitude and foot force, and rotary encoders connected with servomotors.
This paper analyses the motion energy of the four-foot walking robot while statically and steadily striding over standing obstacle, the model of energy, deduction of joint driving power and analysis of the gait of striding over standing obstacle, finally studies foe relation between driving energy and motion attitude of body, parameter of gait and equipment of structure.
Recently, there is a renewed interest in wonderful varieties of rank two since they were shown to hold a keystone position in the theory of spherical varieties, see [L], [BP], and [K].
We investigate the eigenvalue problem for such systems and the correspondingD-module when the eigenvalues are in generic position.
A characterization of the complexity of a homogeneous space of a reductive groupG is given in terms of the mutual position of the tangent Lie algebra of the stabilizer of a generic point of and the (-1)-eigenspace of a Weyl involution of.
The results demonstrated that the number and position of methoxy groups in ring A enhanced cytotoxicity of the chalcones.
Substituents at the 4th and 5th positions of the target thiazoles were introduced by a Hantzsch reaction, and the chain at the second position was extended through a Sandmeyer reaction, formylation, and Wittig olefination.
The ultrastructure of the muscle spindles adequately reflected the functional status of the postural m.
Postural stability data make it possible to estimate changes taking place in the function of analyzers involved in the maintenance of the upright posture.
The vertical posture stability was assessed in healthy children and children with spastic diplegic cerebral palsy from their postural responses to the presentation of single optokinetic or somatosensory stimuli.
Relative Roles of the Ankle and Hip Muscles in Human Postural Control in the Frontal Plane during Standing
The main goal was to evaluate the relative roles of the ankle and hip muscles in human postural control in the frontal plane during normal upright standing.
