At some stage in the process of a sensorimotor transformation for a reaching movement, information about the current position of the hand and information about the location of the target must be encoded in the same frame of reference in order to compute the hand-to-target difference vector. Two main hypotheses have been proposed regarding this reference frame: an eye-centered frame and a body-c...

To contribute appropriately to voluntary reaching during body motion, vestibular signals must be transformed from a head-centered to a body-centered reference frame. We quantitatively investigated the evidence for this transformation during online reach execution by using galvanic vestibular stimulation (GVS) to simulate rotation about a head-fixed, roughly naso-occipital axis as human subjects...

36 To contribute appropriately to voluntary reaching during body motion, vestibular signals must be 37 transformed from a headto a body-centered reference frame. We quantitatively investigated the 38 evidence for this transformation during online reach execution by using galvanic vestibular 39 stimulation (GVS) to simulate rotation about a head-fixed, roughly naso-occipital axis as human 40 sub...

We review some of the few available nonadiabatic calculations of dipole moments. We show that those carried out in a laboratory–fixed set of coordinate axes are bound to fail and discuss the more reasonable ones in a molecule–fixed reference frame. For completeness we also describe the standard Born–Oppenheimer calculations of dipole moments. We briefly address the experimental estimation of di...

This paper presents a human-robot interface system that enables a user to move a robot by moving his hand. It adopts the technique of the 3D measurement based on the affine invariants from multiple views. In this system, we can choose a reference frame to obtain the 3D hand motion between the user-centered frame and the world-fixed frame. With the former frame, the system interprets the user's ...

Key Frame Selection The middle pane in Fig. 1 shows the three rectangular regions of fixed size around the eyes and mouth, selected on an example frame after aligning it with the reference frame f t0 (a neutral rest pose). These regions are used to build the LBP descriptors which are used to automatically find key frames depicting a similar expression as the reference frame. The right pane show...

"We consider the motion of a viscous imcompressible fluid past rotating rigid body in three-dimensional, where translational and angular velocities are prescribed but time-dependent. In reference frame attached to body, we have non-autonomous Oseen-Navier-Stokes equations fixed exterior domains. We prove existence stability bounded mild solutions time t ONSE three-dimensional domains when coeff...

-A technique to numerically obtain the static equilibrium s ta te of a conventional dragline excavation system is reported, including static pose of the bucket as well as internal loads acting on elements of the excavation system. Equilibrium conditions are generated by numerically integrat ing the dynamic equations of motion with the hoist and drag rope lengths fixed. It is shown tha t this me...

The frontal eye field (FEF), in the prefrontal cortex, participates in the transformation of visual signals into saccade motor commands and in eye-head gaze control. The FEF is thought to show eye-fixed visual codes in head-restrained monkeys, but it is not known how it transforms these inputs into spatial codes for head-unrestrained gaze commands. Here, we tested if the FEF influences desired ...

Analysis of mechanical systems is based on Newton’s laws of motion. Usually, ideal (or point) masses are considered in the analysis, as shown in the Figure 1. Motion is considered with respect to a non-accelerating reference frame, usually a fixed point on earth or another non-accelerating object. The equation of motion for a mass m(t) is based on Newton’s second law which expresses the conserv...
