In Framingham, MA, a pioneering “Networked Geothermal” project is underway to explore the potential of shallow geothermal for district heating and cooling, aiming to lower carbon emissions. During 2022 and 2023, SRG carried out four distributed thermal response tests to… Read More »Learning from the Ground Up (LeGUp)
During construction, continuous monitoring of underground tunnels can mitigate potential hazards and facilitate an in-depth understanding of the ground-tunnel interaction behavior. Traditional vision-based monitoring can directly capture an extensive range of motion but cannot separate the tunnel’s vibration and deformation… Read More »Deformation Monitoring of Tunnel using Phase-based Motion Magnification and Optical Flow
