Development of a 3D Relative Motion Method for Human–Robot Interaction Assessment [PDF]
Sensors, 2022 Exoskeletons have been assessed by qualitative and quantitative features known as performance indicators. Within these, the ergonomic indicators have been isolated, creating a lack of methodologies to analyze and assess physical interfaces. In this sense,

The relative motion of membranes [PDF]
Open Physics, 2010 AbstractThe relative classical motion of membranes is governed by the equation (w β cα c r βa)a = R δγβα r gb x δa p aγ, where w is the hessian. This is a generalization of the geodesic deviation equation and can be derived from the lagrangian p · ṙ. Quantum mechanically the picture is less clear.

On-Orbit Geometric Calibration from the Relative Motion of Stars for Geostationary Cameras [PDF]
Sensors, 2021 Affected by the vibrations and thermal shocks during launch and the orbit penetration process, the geometric positioning model of the remote sensing cameras measured on the ground will generate a displacement, affecting the geometric accuracy of imagery ...

Axes of self-motion and object motion shape how we perceive world-relative motion [PDF]
Scientific ReportsWhen we move through the environment, the direction of objects in the optic array changes, producing an optic flow. To perceive world-relative object motion during self-motion, complex flow vectors are decomposed during a process called flow parsing. The

A paradoxical misperception of relative motion. [PDF]
Proc Natl Acad Sci U S ADetecting the motion of an object relative to a world-fixed frame of reference is an exquisite human capability [G. E. Legge, F. Campbell, Vis. Res. 21 , 205–213 (1981)].

Dynamic illusory waves generated by relative motion in periodic displays [PDF]
i-PerceptionWe describe a new display involving what we are calling ‘dynamic illusory waves’. The display brings together a number of previously documented illusory effects and perceptual mechanisms to generate non-rigidly deforming phantom surfaces that take even ...

Analysis of close approach and collision probability between operational satellites and/ or space debris [PDF]
INCAS Bulletin, 2020 In recent years, the number of space debris has increased significantly, which can threaten the safety of operational satellites. In this paper we developed an accurate model for active satellite protection from collision in order to determine close ...

Simplified Maneuvering Strategies for Rendezvous in Near-Circular Earth Orbits
Aerospace, 2023 The development of autonomous guidance control and navigation systems for spacecraft would greatly benefit applications such as debris removals or on-orbit servicing, where human intervention is not practical.
