A Learning Variable Neighborhood Search Approach for Induction Machines Bearing Failures Detection and Diagnosis

open access: yesEnergies, 2020
This paper proposes a three-phase metaheuristic-based approach for induction machine bearing failure detection and diagnosis. It consists of extracting and processing different failure types features to set up a knowledge base, which contains different ...

Influence of Timing of Postoperative Weight-Bearing on Implant Failure Rate Among Older Patients With Intertrochanteric Hip Fractures: A Propensity Score Matching Cohort Study

open access: yesFrontiers in Medicine, 2021
Introduction: The purpose of this study was to determine whether immediate weight-bearing as tolerated increased the risk of implant failure and decreased functional outcomes compared with restricted weight-bearing.Methods: From January 2010 to December ...
