Joint errors are inevitable in robot manipulation. These uncertainties propagate to give rise to translational and orientational errors in the position and orientation of the robot end-effector. The displacement of the active vision head mounted on the robot endeffector produces distortion of the projected object on the image. Upon active visual inspection, the observed dimension of a mechanica...

Many sensorimotor neurons in the CNS encode global parameters of limb movement and posture rather than specific muscle or joint parameters. Our investigations of spinocerebellar activity have demonstrated that these second-order spinal neurons also may encode proprioceptive information in a limb-based rather than joint-based reference frame. However, our finding that each foot position was dete...

The interpretation of joint kinematics data in terms of displacements is a product of the type of movement, the measurement technique and the underlying model of the joint implemented in optimization procedures. Kinematic constraints reducing the number of degrees of freedom (DOFs) are expected to compensate for measurement errors and noise, thus, increasing the reproducibility of joint angles....

In this paper, we introduce our algorithms for simulating humanoid robots, in particular the parallel linear-time forward dynamics algorithm and constraint-based contact model. Using a small humanoid robot as an example, we also demonstrate that our simulator provides results qualitatively similar to experiments even with high-gain joint servo model, which can be simulated without precise joint...

In Vehicle-to-Everything (V2X) communication, the high mobility of vehicles generates Doppler shift which leads to channel uncertainties. Moreover, reasons for uncertainties also include finite feedback, state information (CSI) loss and latency. With this concern, we formulate a joint spectrum power allocation problem V2X communication with imperfect CSI. Specifically, sum capacity cellular use...

In this study, experimental and numerical investigations were carried out to achieve a comprehensive understanding of the impact surface conditions on self-piercing riveting (SPR) joint quality. Oil lubrication sandpaper grinding employed in tests change at rivet/top sheet, top/bottom sheets bottom sheet/die interfaces. A finite element (FE) model for SPR process was also adopted numerically as...

Purpose – The present experiment aimed to test the impact of a self-regulatory strategy of goal pursuit – called mental contrasting with implementation intentions (MCII) – on an integrative bargaining task. Design/methodology/approach – Participants were randomly assigned to dyads and negotiated over the sale of a car. Before negotiating, participants were prompted to engage in MCII, or one or ...

PURPOSE It has been suggested that during running proper coordination between subtalar joint pronation/supination and knee joint flexion/extension via tibial rotation is important to attenuate ground reaction impact forces (GRIF). Lack of coordination may produce over time a wide range of injuries. The goal of this study was to investigate the relationship between subtalar pronation/supination ...
