New electricity grids possible with computer simulations

Detail of a simulation of a pulsed positive discharge near a dielectric rod, made by Anna Dubinova. Credit: CWI Renewable energy requires new electricity grids, sometimes over entire continents, because ‘green energy’ is often generated in remote locations. A general problem in such networks is that, although electrically conductive parts are separated from their environment…

Researchers plumb the secrets of tissue paper

UBC mechanical engineering researchers Srikanth Phani, Kui Pan and Sheldon Green Credit: UBC Canada’s tissue manufacturers are now much closer to producing the perfect paper, thanks to new UBC research. A team working with UBC mechanical engineering professors Sheldon Green and Srikanth Phani have created what is likely the first complete mathematical model of creping,…
