A novel multidimensional uncalibration method applied to six-axis manipulators
This study proposes a multidimensional uncalibrated technique for tracking and grasping dynamic targets by a robotic arm in the eye-in-hand mode. This method avoids complex and cumbersome calibration processes, enabling machine vision tasks to be ...

Unscented Particle Filter for Online Total Image Jacobian Matrix Estimation in Robot Visual Servoing
The main purpose of visual servoing is to control the motion of a robot system based on visual information provided by one or more cameras. It is an important research topic in the robotics community.

Iterative Solutions to the Inverse Geometric Problem for Manipulators with no Closed Form Solution [PDF]
A set of new iterative solutions to the inverse geometric problem is presented. The approach is general and does not depend on intersecting axes or calculation of the Jacobian.

The jacobian problem for singular surfaces
We consider normal affine surfaces $X$ with étale endomorphisms. It is proved that if $X$ has at least one singular point which is not a quotient singular point then such an endomorphism is an isomorphism.

A numerical solution of parabolic quasi-variational inequality nonlinear using Newton-multigrid method [PDF]
In this article, we apply three numerical methods to study the L∞-convergence of the Newton-multigrid method for parabolic quasi-variational inequalities with a nonlinear right-hand side.

Retrieving 3D distributions of atmospheric particles using Atmospheric Tomography with 3D Radiative Transfer – Part 1: Model description and Jacobian calculation [PDF]
Our global understanding of clouds and aerosols relies on the remote sensing of their optical, microphysical, and macrophysical properties using, in part, scattered solar radiation.

Long step homogeneous interior point algorithm for the p* nonlinear complementarity problems [PDF]
A P*-Nonlinear Complementarity Problem as a generalization of the P*-Linear Complementarity Problem is considered. We show that the long-step version of the homogeneous self-dual interior-point algorithm could be used to solve such a problem.
