Spin 1/2 one‐ and two‐particle systems in physical space without eigen‐algebra or tensor product [PDF]

open access: yesMathematical methods in the applied sciences, 2021
Under the spin–position decoupling approximation, a vector with a phase in 3D orientation space endowed with geometric algebra substitutes the vector–matrix spin model built on the Pauli spin operator.

Design and Implementation of a 3-Dimensional Attitudes Estimator Device using Low Cost Accelerometer & Gyroscope with Microcontroller IDE [PDF]

open access: yesINCAS Bulletin, 2020
Navigation and guidance systems for most automobile as well as aerospace applications require a coupled chip setup known as Inertial Measurement Units (IMU) which, depending on the degree of freedoms, contains a Gyroscope (for maintaining orientation and

An Algorithm for Calculating Apple Picking Direction Based on 3D Vision

open access: yesAgriculture, 2022
Research into autonomous (robotic) apple picking has not yet resolved the problem of finding the optimal picking orientation. Robotic picking efficiency, in terms of picking all available apples without loss or damage, remains low.

A fault monitoring method for wind power generation system based on sliding mode observer

open access: yesArchives of Electrical Engineering, 2020
In this paper, a rotor current fault monitoring method is proposed based on a sliding mode observer. Firstly, the state-space model of the Double-Fed Induction Generator (DFIG) is constructed by vector transformation.

The paradigm shift in intercultural communication in digital space [PDF]

open access: yesE3S Web of Conferences, 2021
The paradigm of intercultural communication has changed its vector orientation in a period of digital space expansion. Previously existing behavioral patterns, which included basic components, have led to the emergence of new behavioral patterns through ...

On the Merits of Joint Space and Orientation Representations in Learning the Forward Kinematics in SE(3)

open access: yesRobotics: Science and Systems, 2019
This paper investigates the influence of different joint space and orientation representations on the approximation of the forward kinematics. We consider all degrees of freedom in three dimensional space SE(3) and in the robot’s joint space Q.

Algebra of Complex Vectors and Applications in Electromagnetic Theory and Quantum Mechanics

open access: yesMathematics, 2015
A complex vector is a sum of a vector and a bivector and forms a natural extension of a vector. The complex vectors have certain special geometric properties and considered as algebraic entities. These represent rotations along with specified orientation

Determinig of an object orientation in 3D space using direction cosine matrix and non-stationary Kalman filter

open access: yesArchives of Control Sciences, 2016
This paper describes a method which determines the parameters of an object orientation in 3D space. The rotation angles calculation bases on the signals fusion obtained from the inertial measurement unit (IMU).
