An overview and comparative analysis of Recurrent Neural Networks for Short Term Load Forecasting

open access: yes, 2017
The key component in forecasting demand and consumption of resources in a supply network is an accurate prediction of real-valued time series. Indeed, both service interruptions and resource waste can be reduced with the implementation of an effective ...

Failure mechanics in low-velocity impacts on thin composite plates [PDF]

open access: yes
Eight-ply quasi-isotropic composite plates of Thornel 300 graphite in Narmco 5208 epoxy resin (T300/5208) were tested to establish the degree of equivalence between low-velocity impact and static testing.
