Simulating Extreme Storms over the Alabama-Coosa-Tallapoosa River Basin

May 8, 2017

A numerical weather forecasting model (WRF) was used to simulate 120 storms over the Alabama-Coosa-Tallapoosa (ACT) river basin to explore the effect of climate change on probable maximum precipitation (PMP).  

PMP is defined as the largest rainfall depth that could physically...

Cryogenic Memory Cell Design Based on Small Coupled Arrays of Josephson Junctions

February 27, 2017

Researchers proposed a cryogenic memory cell design that has a potential to substantially outperform the existing memory cells, achieve much faster access times and lower access and dissipation energies, and reduce the size of the memory cell. Designing fast, energy efficient and small...
