To realize the harmonious cooperation with the operator, the man-machine cooperative system must be designed so as to accommodate with the characteristics of the operator’s skill. One of the important considerations in the skill analysis is to investigate the switching mechanism underlying the skill dynamics. On the other hand, the combination of the feedforward and feedback schemes has been pr...
W eightlifting is a sport in which athletes compete for the total weight of 2 lifts: the snatch and the clean and jerk. The training methods used in this sport are also used as a method of strength training for a wide range of other sports. Weightlifting exercises can be effective for enhancing athletic performance that requires high-load speed strength such as football, basketball, volleyball,...
– 2 – We analyze the Galactic bulge microlensing event MOA 2003-BLG-37. Although the Einstein timescale is relatively short, t E = 43 days, the lightcurve displays deviations consistent with parallax effects due to the Earth's accelerated motion. We show that the χ 2 surface has four distinct local minima that are induced by the " jerk-parallax " degeneracy, with pairs of solutions having proje...

Step response is widely used as the performance index of controlled systems. Thus, the ideal system would be one that has an output which approaches to the step signal quickly without error or over-shoot. However, if the output of an actual plant converges to the reference signal in a very short period, it can be dangerous to the surrounding environment as well as the operators. Furthermore, th...
This paper presents a method to determine trajectory for robot that involves a close interaction between robotic systems and human beings.The proposed method considers robot trajectory as path in operational space and time rhythm distinct problems verifying the natural smoothness of voluntary human movement. Operational space path is determined experimentally as individual movement pattern. The...
In this work, we propose a convenient method for evaluating levels of angular jerk in augmented reality (AR) and virtual (VR). Jerk is rarely analyzed metric usability studies, although it can be measured calculated easily with most head-worn displays yield highly relevant information to designers. Here, developed implemented system capable calculating analyzing real-time based on orientation d...
This work deals with jerk–continuous trajectory planning for robotic manipulators by means of the fourth-order S-curve to ensure motion smoothness. The algorithm presented in this can cause acceleration and jerk stay a saturated state order improve efficiency robot’s programming operation. Moreover, multi-axis synchronization is proposed integrated enhanced stability terms generated synchronize...
An analysis of the results of an algorithm for optimal trajectory planning of robot manipulators is described in this paper. The objective function to be minimized is a weighted sum of the integral squared jerk and the execution time. Two possible primitives for building the trajectory are considered: cubic splines or fifth-order B-splines. The proposed technique allows to set constraints on th...
Sensory signals undergo substantial recoding when neural activity is relayed from sensors through pre-thalamic and thalamic nuclei to cortex. To explore how temporal dynamics and directional tuning are sculpted in hierarchical vestibular circuits, we compared responses of macaque otolith afferents with neurons in the vestibular and cerebellar nuclei, as well as five cortical areas, to identical...
