Dual Quaternion Functions and Its Applications [PDF]

open access: yesJournal of Applied Mathematics, 2013
A dual quaternion is associated with two quaternions that have basis elements e0, e1, e2, e3, and ε. Dual numbers are often written in the form z=ζ+εζ*, where ε is the dual identity and has the properties ε2=0  (ε≠0).

Robust Pose and Inertial Parameter Estimation of an Unknown Aircraft Based on Variational Bayesian Dual Vector Quaternion Extended Kalman Filter. [PDF]

open access: yesEntropy (Basel)
Accurately determining the parameters of an unmodeled spacecraft is crucial. Filtering methods that are resilient to uncertainty, employing dual quaternion frameworks to ascertain orientation and position, introduce a design for an extended Kalman filter

Adaptive pose and inertial parameters estimation of free-floating tumbling space objects using dual vector quaternions

open access: yesAdvances in Mechanical Engineering, 2017
The robust parameter estimation of unknown space objects is essential to the on-orbit servicing missions. Based on the adaptive filtering techniques along with the dual quaternions modeling methods for pose estimation, this article proposes a dual vector

Dual third-order Jacobsthal quaternions [PDF]

open access: yesProyecciones (Antofagasta), 2018
In 2016, Yüce and Torunbalcı Aydın (18) defined dual Fibonacci quaternions. In this paper, we defined the dual third-order Jacobsthal quaternions and dual third-order Jacobsthal-Lucas quaternions. Also, we investigated the relations between the dual third-order Jacobsthal quaternions and third-order Jacobsthal numbers.

Spacecraft Robot Kinematics Using Dual Quaternions

open access: yesRobotics, 2018
In recent years, there has been a growing interest in servicing orbiting satellites. In most cases, in-orbit servicing relies on the use of spacecraft-mounted robotic manipulators to carry out complicated mission objectives.

Kinematic-Model-Free Orientation Control for Robot Manipulation Using Locally Weighted Dual Quaternions

open access: yesRobotics, 2020
Conventional control of robotic manipulators requires prior knowledge of their kinematic structure. Model-learning controllers have the advantage of being able to control robots without requiring a complete kinematic model and work well in less ...

A High-Precision Hand-Eye Coordination Localization Method under Convex Relaxation Optimization. [PDF]

open access: yesSensors (Basel)
Traditional switching operations require on-site work, and the high voltage generated by arc discharges can pose a risk of injury to the operator. Therefore, a combination of visual servo and robot control is used to localize the switching operation and ...

Dual-Quaternions: Theory and Applications in Sound

open access: yesCoRR, 2023
Sound is a fundamental and rich source of information; playing a key role in many areas from humanities and social sciences through to engineering and mathematics. Sound is more than just data 'signals'. It encapsulates physical, sensorial and emotional, as well as social, cultural and environmental factors.

Dual Quaternions and Dual Quaternion Vectors

open access: yesCommunications on Applied Mathematics and Computation, 2022
We introduce a total order and the absolute value function for dual numbers. The absolute value function of dual numbers are with dual number values, and have properties similar to the properties of the absolute value function of real numbers. We define the magnitude of a dual quaternion, as a dual number.
