Finite-Time Tracking Controller Design of Perturbed Robotic Manipulator Based on Adaptive Second-Order Sliding Mode Control Method

IEEE Access, 2021
This article presents an adaptive finite time second-order sliding mode tracking control scheme for robotic manipulators. A new control law is suggested to force the trajectories of the robot manipulator to move from all initial conditions to ...

Educational manipulation robot

AUTOBUSY – Technika, Eksploatacja, Systemy Transportowe, 2019
The article presents a project of the small articulated, educational robot with five degrees of freedom. There were described elements of the mechanical part of the structure and the control system based on LabVIEW and the Arduino platform. Apart of steerage and simple programming of manipulators movements, a measuring system was created using the ...

Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Parallel Robot Translational Performance Evaluation through Direction-Selective Index (DSI)

Journal of Robotics, 2011
Performance indexes usually provide global evaluations of robot performances mixing their translational and/or rotational capabilities. This paper proposes a definition of performance index, called direction-selective index (DSI), which has been ...

The Application of ZFD Formula to Kinematic Control of Redundant Robot Manipulators With Guaranteed Motion Precision

IEEE Access, 2018
Zhang et al. recently design a special difference formula called the Zhang finite-difference (ZFD) formula. This paper applies the ZFD formula for the kinematic control of redundant robot manipulators, due to its good performance in approximating first ...
