Kinematic Comparisons of Hybrid Mechanisms for Bone Surgery: 3-PRP-3-RPS and 3-RPS-3-PRP

Machines, 2022
This paper proposes an approach to derive the Jacobian matrix of a hybrid mechanism by applying a velocity operator to the transformation matrix. This Jacobian matrix is capable of deducing hybrid singularities, which cannot be identified by using the ...

Per-unit Scheme for Integrated Solution of Hybrid Power-water Flow Problem

Journal of Modern Power Systems and Clean Energy, 2023
When applying the widely-used Newton-Raphson (N-R) method to the integrated solution of the hybrid power-water flow problem of the power-water integrated energy system (PW-IES), it is found that there are numerical differences among Jacobian elements ...

The monodromy pairing and discrete logarithm on the Jacobian of finite graphs

Journal of Mathematical Cryptology, 2010
Every graph has a canonical finite abelian group attached to it. This group has appeared in the literature under a variety of names including the sandpile group, critical group, Jacobian group, and Picard group.

Study of the Jacobian of an extended Kalman filter for soil analysis in SURFEXv5 [PDF]

Geoscientific Model Development, 2015
An externalised surface scheme like SURFEX allows computationally cheap offline runs. This is a major advantage for surface assimilation techniques such as the extended Kalman filter (EKF), where the offline runs allow a cheaper numerical ...

On the Jacobian Conjecture [PDF]

Proceedings of the American Mathematical Society, 1993
We show that the Jacobian conjecture can be reduced to a weaker conjecture in which all fibers of coordinate functions are irreducible.

On the Kinematics of Robotic-assisted Minimally Invasive Surgery [PDF]

Modeling, Identification and Control, 2013
Minimally invasive surgery is characterized by the insertion of the surgical instruments into the human body through small insertion points called trocars, as opposed to open surgery which requires substantial cutting of skin and tissue to give the ...
