The modified Borg cycle strength test (mBCST): Feasibility and physiological response in people with COPD and healthy older adults

Experimental Physiology, EarlyView.
Abstract Accurate prescription of supramaximal exercise requires exercise tests covering the intensity domain between maximal aerobic and peak power output. All‐out tests are commonly used for this objective but are considered challenging for people with chronic obstructive pulmonary disease (COPD) due to the extreme physiological demand.

Convolutional LSTM-based Frequency Nadir Prediction

2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE), 2021
The frequency nadir of post-disturbance power system is crucial to system stability. To predict this value fast and accurately provides a valuable reference for online security and stability control strategies. As methods based on physical models and shallow learning are getting harder and harder to improve prediction performance, this paper proposes a

Nadir Frequency Estimation in Low-Inertia Power Systems

2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020
Increasing amounts of non-synchronous generation in power grids are bringing reductions in system inertia. In a grid with extremely low inertia, the estimation of frequency indicators such as the frequency nadir can be used to feed into predictive system controls that would avoid nuisances such as triggering system protection systems, avoiding needless

An Analytical Model for Frequency Nadir Prediction Following a Major Disturbance

IEEE Transactions on Power Systems, 2020
The frequency nadir is a significant indicator for the primary frequency response monitoring and control. It is imperative to predict the maximum frequency deviation and the time at which the maximum occurs with high efficiency and accuracy following a major disturbance. To develop an analytical model for the frequency nadir prediction, the closed-loop
