A 500-million-year-old enigma concerning ancient squid-like creatures has at last been deciphered.
Researchers from the University of Bristol in England have solved this puzzle, thanks to fossils excavated in North Greenland.
For a long…

Effect of friction stir processing parameters on mechanical properties of different aluminum alloy plates
Signal-to-noise ratio
The SN ratio is evaluated based on the quality of the intended responses. The objective function in this search is maximization of the responses (UTS, YS, El%, HV), so the larger the response, the better the SN ratio is to be…

Data-driven EV charging infrastructure with uncertainty based on a spatial–temporal flow-driven (STFD) models considering batteries
EV charging facility allocation
we employ a sophisticated model called the ST-FCLM that was created to situate various EV charging stations on the transportation network15.
The ST-FCLM plans three facility types—OWCs, FCS, and PL—addressing the…
