We previously showed that, when observers watch an actor performing a predictable block-stacking task, the coordination between the observer's gaze and the actor's hand is similar to the coordination between the actor's gaze and hand. Both the observer and the actor direct gaze to forthcoming grasp and block landing sites and shift their gaze to the next grasp or landing site at around the time...

We hypothesize that application of an unopposed quadriceps force coupled with an impulsive ground reaction force may induce anterior cruciate ligament (ACL) injury. This situation is similar to landing from a jump if only the quadriceps muscle is active; an unlikely but presumably dangerous circumstance. The purpose of this study was to test our hypothesis using in vitro simulation of jump land...

Introduction: To search for subsurface interfaces and characterize surface roughness, the Shallow Radar (SHARAD) instrument on the Mars Reconnaissance Orbiter is observing past, present, and proposed future Martian landing sites. Orbital and landed imagery and altimetry data show that most sites are located atop layered sequences that extend over tens to hundreds of kilometers and are hundreds ...

INTRODUCTION: Landing is a common manoeuvre in sporting activities that can often lead to anterior cruciate ligament (ACL) injury with greater risk found in females [1]. Single-leg landing increases the risk of injury compared to double-leg landing because it is performed with less knee flexion and provides less stability. Although there has shown to be significant differences in maximum valgus...

Coordinated landing requires anticipating the timing and magnitude of impact, which in turn requires sensory input. To better understand how cane toads, well known for coordinated landing, prioritize visual versus vestibular feedback during hopping, we recorded forelimb joint angle patterns and electromyographic data from five animals hopping under two conditions that were designed to force ani...

This paper focuses on the aircraft landing optimization problem where both the landing routes and the landing order of aircrafts should be optimized to minimize an occupancy time of airport, and proposes its optimization method which is robust to dynamical situations such as weather condition change and other aircrafts’ landing routes change. As a difficulty of this optimization problem, approp...

Autonomous landing is a challenging but important task for Unmanned Aerial Vehicles (UAV) to achieve high level of autonomy. The fundamental requirement for landing is the knowledge of the height above the ground, and a properly designed controller to govern the process. This paper presents our research results in the study of landing an autonomous helicopter. The above‐the‐ground hei...
