PhD Candidate, Bodhinanda Chandra, Prof. Kenichi Soga, and collaborators from Kyoto University, Hiroshima University, and MIT recently published a paper in Computer Methods in Applied Mechanics and Engineering, entitled “Stabilized mixed material point method for incompressible fluid flow analysis” (https://doi.org/10.1016/j.cma.2023.116644). In the proposed work, a stabilized mixed material point method (MPM) formulation is developed to simulate a stable and accurate simulation of incompressible fluid flows. The developed formulation… Read More »A new article in CMAME on Mixed MPM

The members of the Smart and Connected Communities Project hosted the Marin Community Workshop at the College of Marin, Kentfield Campus on October 26, 2023. In this workshop, we shared updates on the simulations related to wildfires and evacuations, findings from interviews, and initial directions for the games.

Pengshun, a Ph.D. student at the SRG, presented at the 2023 INFORMS Annual Meeting held on October 15-18, 2023, at the Phoenix Convention Center in Phoenix. His presentation was entitled “Spatial-queue Based Mesoscopic Traffic Model and its Applications in Wildfire Evacuation Simulations”. To capture highly dynamic traffic situations, efficient mesoscopic models can deliver comprehensive yet fast results. Therefore, in this work, Bingyu and Pengshun developed… Read More »Pengshun’s Presentation at the 2023 INFORMS Annual Meeting

Students of CE 170A (Infrastructure Sensing and Modeling, taught by Professor Soga, Professor Kayen, and Professor Zekkos) had a lot of fun on September 6th. Model bridge tests were conducted as part of the Infrastructure Sensing module of the course, led by Connor and Shih-Hung. Three different bridges (control, member defect, connection defect) were instrumented with distributed fiber optic sensors, linear variable differential transformers (LVDTs),… Read More »Model Bridge Tests for CE 170A: Infrastructure Sensing and Modeling (Fall 2023)

The Soga Research Group/Center for Smart Infrastructure, in partnership with Caltrans, is employing distributed fiber optic sensing and pore pressure transducers to monitor the geotechnical capacity of Cast-in-Steel-Shell (CISS) concrete piles in relation to soil plug thickness. This research seeks to analyze data across different construction phases, aiming to gain insights into this correlation and its comparison to conventional design practices. The study employs field… Read More »Using fiber optic sensing to assess cast-in-steel-shell concrete piles

The NSF-funded Smart and Connected Communities (SCC) Project team, led by Professor Kenichi Soga, CITRIS scholar Louise Comfort, and post-doc Seunghyun Lee, organized a pair of kickoff community workshops designed to promote collaboration and engagement. These workshops were held on February 15th at the East Bay Municipal Utility District’s (EBMUD) headquarters office in Oakland and on May 10th at the Marin Wildfire Prevention Authority in… Read More »NSF-Funded Project Team Hosts Community Workshops

On September 14th-15th, the SRG MPM team, John, Nanda, Joel, and Lauren, attended the MPM Workshop 2023 held at the University of Maine in Bangor, Maine, together with Saki, a visiting scholar from Kajima. At the conference, John, Nanda, Joel, and Lauren presented their research with the following title: John Murphy, “Discussion of Transition Zones in Double-Point Formulation for Erosion Problems“. Bodhinanda Chandra, “Development of… Read More »SRG attended the MPM Workshop 2023 in Bangor, Maine

Prof. Soga and the group members attended the 4th International Symposium on Machine Learning & Big Data in Geoscience (ISMLG 2023, https://www.ismlg2023.com/) at University College Cork, Ireland, from August 29 to September 1, 2023. In the symposium, Prof. Soga delivered a keynote lecture titled “Smart Geo-Infrastructure – From Sensing to Machine Learning“.  The group’s postdoc, Dayu Apoji, presented two pieces of his work, titled “Modelling Steering… Read More »SRG in ISMLG 2023, Cork, Ireland

Dayu participated in UC Berkeley’s Ph.D. commencement in the spring of 2023 on Thursday, May 18th. The memorable occasion was captured in photos, including the hooding session by Professor Soga and a moment with Berkeley Geosystems Engineering faculty and other Ph.D. graduates in front of the iconic UC Berkeley Campanile (photos by CoE). Dayu has now accepted a postdoctoral position within the same group, where… Read More »PhD Graduation Commencement 2023

To ensure the highest standards of safety and efficiency, we deploy Boston Dynamics’ Spot robot into the tunnel for inspection. SPOT is a quadruped terrestrial robot known for its agility and adaptability, and comes equipped with advanced sensors, transforming traditional tunnel inspection practices. Key to Spot’s tunnel inspection capabilities is its state-of-the-art 3D camera. This system enables the robot to do high-quality visual inspection. The… Read More »EBMUD USL Tunnel Inspection using Boston Dynamics’ Spot Robot Equipped with Advanced Sensor Technology
