A Hybrid Wired/Wireless Deterministic Network for Smart Grid

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
With the rapid growth of time-critical applications in smart grid, robotics, autonomous vehicles, and industrial automation, demand for high reliability, low latency and strictly bounded jitter is sharply increasing. High-precision time synchronization

Real-Time Low-Frequency Oscillations Monitoring

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
A major concern for interconnected power grid systems is low frequency oscillation, which limits the scalability and transmission capacity of power systems. Un-damped, or poorly-damped oscillations will lead to undesirable conditions or even a catastrophic

Programmable System on Chip for controlling an atomic physics experiment

July 23, 2021
Author(s)
Ananya Sitaram, Gretchen K. Campbell, Alessandro Restelli
Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted the barriers to using
