Electromagnetic time reversal for online partial discharge location in power cables: Influence of interfering reflections from grid components

Marcos Rubinstein, Farhad Rachidi-Haeri

In online single-sided partial discharge (PD) location, the measured PD reflection patterns are affected by the characteristics of all the components of the associated power network. This paper analyses the performance of a PD location method based on elec ...

Pure Isotropic Proton NMR Spectra in Solids using Deep Learning

David Lyndon Emsley, Daria Torodii, Pinelopi Moutzouri, Manuel Cordova, Bruno Simões de Almeida

The resolution of proton solid-state NMR spectra is usually limited by broadening arising from dipolar interactions between spins. Magic-angle spinning alleviates this broadening by inducing coherent averaging. However, even the highest spinning rates expe ...
