Comparison of the Strength of the Ankle Evertor, Invertor, and Ratio at Different Ankle and Toe Positions Between Sides With and Without Chronic Ankle Instability in Taekwondo Athletes

Physical Therapy Korea
Background: In Taekwondo athletes, ankle sprain is the most common risk factor for injury. Repeated ankle injuries lead to weakness and imbalance of the ankle muscles, resulting in chronic ankle instability (CAI).

Feature Learning With a Divergence-Encouraging Autoencoder for Imbalanced Data Classification

IEEE Access, 2018
Imbalanced data exists commonly in machine learning classification applications. Popular classification algorithms are based on the assumption that data in different classes are roughly equally distributed; however, extremely skewed data, with instances ...

A Unified Method for Online Detection of Phase Variables and Symmetrical Components of Unbalanced Three-Phase Systems with Harmonic Distortion

Energies, 2019
This paper presents a method for online detection of symmetrical components of arbitrarily distorted and biased three-phase input signals. This method is based on Second-Order Generalized Integrators (SOGIs), for which a new tuning based on a gradient ...
