Open AccessA strategy for out-of-roundness damage wheels identification in railway vehicles based on sparse autoencoders
Wayside monitoring is a promising cost-effective alternative to predict damage in the rolling stock. The main goal of this work is to present an unsupervised methodology to identify out-of-roundness (OOR) dama...

Phenolics extraction from sweet potato peels: modelling and optimization by response surface modelling and artificial neural network
Sweet potato peels (SPP) are a major waste generated during root processing and currently have little commercial value. Phenolics with free radical scavenging activity from SPP may represent a possible added-v...
