A new implementation for online calculation of manipulator Jacobian.
PLoS ONE, 2019 This paper describes a new implementation for calculating Jacobian and its time derivative for robot manipulators in real-time. The estimation of Jacobian is the key in the real-time implementation of kinematics and dynamics of complex planar or spatial ...

A note on analyzing the stability of oscillator Ising machines
Electronics Letters, 2023 The rich non‐linear dynamics of the coupled oscillators (under second harmonic injection) can be leveraged to solve computationally hard problems in combinatorial optimization such as finding the ground state of the Ising Hamiltonian. While prior work on

Jacobian matrices of Y-seed mutations [PDF]
Advances in Applied Mathematics, 2020 For any quiver mutation sequence, we define a pair of matrices that describe a fixed point equation of a cluster transformation determined from the mutation sequence. We give an explicit relationship between this pair of matrices and the Jacobian matrix of the cluster transformation. Furthermore, we show that this relationship reduces to a relationship

Development of derivation of inverse Jacobian matrices for 195 6-DOF GSP mechanisms [PDF]
, 2016 One of the key issues in robotics is finding high-performance manipulator structures. To evaluate the performance of a parallel manipulator, researchers mostly use kinematic performance indices (such as condition number, minimum singular value, dexterity,

Type Synthesis of Fully-Decoupled Three-Rotational and One-Translational Parallel Mechanisms
International Journal of Advanced Robotic Systems, 2016 Based on screw theory and the principle of one- leg driving by an independent motor, a methodology for the structural synthesis of fully-decoupled three-rotational and one-translational (3R1T) parallel mechanisms is proposed by analysing the ...

Fibers of rational maps and Jacobian matrices
Journal of Algebra, 2021 A rational map $ϕ: \mathbb{P}_k^m \dashrightarrow \mathbb{P}_k^n$ is defined by homogeneous polynomials of a common degree $d$. We establish a linear bound in terms of $d$ for the number of $(m-1)$-dimensional fibers of $ϕ$, by using ideals of minors of the Jacobian matrix. In particular, we answer affirmatively Question~11 in arXiv:1511.02933v2.
