Validation of the Spinal Instability Neoplastic Score: A Retrospective Analysis

open access: yesGlobal Spine Journal, 2015
Introduction With improved survival rates of cancer patients, the incidence of spinal metastases is increasing. Spinal metastases increase the risk for pathological fractures that subsequently increase the risk of spinal instability, spinal cord ...

Research on the Strategy of Motion Constraint-Aided ZUPT for the SINS Positioning System of a Shearer

open access: yesMicromachines, 2017
The accurate measurement of position and orientation for shearers is a key technology in realizing an automated, fully-mechanized, coal mining face. Since Global Positioning System (GPS) signal cannot arrive at the coal mine underground, wireless sensor ...

An Innovative High-Precision Scheme for a GPS/MEMS-SINS Ultra-Tight Integrated System

open access: yesSensors, 2019
The Doppler-assisted error provided by a low-precision microelectromechanical system (MEMS) strapdown inertial navigation system (SINS) increases rapidly. Therefore, the bandwidth of the tracking loop for a global positioning system (GPS)/MEMS-SINS ultra-

A Novel SINS/IUSBL Integration Navigation Strategy for Underwater Vehicles

open access: yes, 2019
This paper presents a novel SINS/IUSBL integration navigation strategy for underwater vehicles. Based on the principle of inverted USBL (IUSBL), a SINS/IUSBL integration navigation system is established, where the USBL device and the SINS are both ...

A Fault-Tolerant Polar Grid SINS/DVL/USBL Integrated Navigation Algorithm Based on the Centralized Filter and Relative Position Measurement

open access: yesSensors, 2019
Navigation is a precondition for ocean space vehicles to work safely in polar regions. The traditional polar algorithms employ the grid strapdown inertial navigation system (SINS) as the backbone and Doppler velocity log (DVL) output velocity as ...
