Design and Development of Novel Airway Device for Transoral Respiratory Monitoring During Sedation
The Laryngoscope, EarlyView.This article describes iterative design factors and results of clinical testing for a novel medical device that promotes transoral respiratory gas exchange for patients during sedation. A minimally viable prototype was 3D printed from thermoplastic polyurethane and demonstrated high levels of oral retention, gas exchange, and satisfaction among ...

Land Degradation &Development, EarlyView.ABSTRACT Territorial spatial optimization is a key strategy to promote long‐term regional sustainable development. Although ant colony optimization (ACO) is widely used in territorial spatial optimization, it is prone to local optima and offers limited integration of spatial suitability and regional heterogeneity. To address these problems, an adaptive

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,
