Design of steering control system maintaining ship's rotation in strong wind (Servo type generalized minimum variance control with adjusting wind effect)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
A ship is turned by steering. Then the ship is turned with constant angular velocity against the steering angle. However, the turning angular velocity is varied by blowing strong wind.

‘Whip from the hip’: thigh angular motion, ground contact mechanics, and running speed

open access: yesBiology Open, 2020
During high-speed running, lower limb vertical velocity at touchdown has been cited as a critical factor needed to generate large vertical forces. Additionally, greater leg angular velocity has also been correlated with increased running speeds. However,

Analysis and Correction of the Rolling Shutter Effect for a Star Tracker Based on Particle Swarm Optimization

open access: yesRemote Sensing, 2022
The rolling shutter effect decreases the accuracy of the attitude measurement of star trackers when they work in rolling shutter exposure mode, especially under dynamic conditions.

Attitude control of on-orbit capture spacecraft with angular velocity constraint

open access: yesXibei Gongye Daxue Xuebao, 2022
Aiming at the attitude control problem of spacecraft in the capturing non-cooperative target process, a dual tracking robust adaptive attitude controller is designed. Firstly, a bounded virtual angular velocity is designed for the kinematics equations to

Defining the Consistent Velocity of Omnidirectional Mobile Platforms

open access: yesMachines
The maximum linear (or translational) velocity achievable by an omnidirectional platform is not uniform as it depends on the angular orientation of the motion.

AMRTA-X: Grasp Kinematic Analysis during Myoelectric Prehension Orthosis and Body Powered Prehension Orthosis's Usage on Brachial Plexus Injury Patients

open access: yesFolia Medica Indonesiana, 2021
Brachial Plexus Injury (BPI) results in decreased motor function in upper extremity and leads to reduced hand grasping movement. Orthotic prehension is designed to create artificial grasp movements in paralyzed hand.

Animal behavior: Timing escape on angular size or angular velocity?

open access: yesCurrent Biology, 2023
Animals avoid rapidly approaching objects. In many arthropods, angular size is a common visual cue used to decide the time of avoidance. A new study shows that fiddler crabs decide when to escape based on object angular expansion velocity.

India plate angular velocity and contemporary deformation rates from continuous GPS measurements from 1996 to 2015

open access: yesScientific Reports, 2017
We estimate a new angular velocity for the India plate and contemporary deformation rates in the plate interior and along its seismically active margins from Global Positioning System (GPS) measurements from 1996 to 2015 at 70 continuous and 3 episodic ...

On Centroidal Dynamics and Integrability of Average Angular Velocity [PDF]

open access: yesIEEE Robotics and Automation Letters, 2017
In the literature on robotics and multibody dynamics, the concept of average angular velocity has received considerable attention in recent years. We address the question of whether the average angular velocity defines an orientation frame that depends ...
