Colloquia

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Matthew Weingarten, San Diego State University, Earth and Environmental Sciences ABSTRACT: Large-scale enhanced geothermal system (EGS) energy production is rapidly advancing through the use of multi-stage stimulation of horizontal wells. We analyze the first two years of continuous circulation at EGS Project Red, Nevada, drawing on publicly reported […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Damian Rouson, Lawrence Berkeley National Laboratory ABSTRACT: The advent of AI-generated code offers an opportunity to shift research software engineers’ activity away from fine-grained algorithm implementations and towards high-level problem specifications, code review, and software verification. This talk will demonstrate how Berkeley Lab’s Formal open-source the software framework […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Perry Johnson, UC, Irvine ABSTRACT: Direct numerical simulation (DNS) of turbulence is often prohibitively expensive for high Reynolds number flows involving turbulent boundary layers. Therefore, computer simulation of these flows inevitably encounters a trade-off between physical fidelity and computational cost. Reynolds-averaged Navier-Stokes (RANS) has long been the predominant […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Jonah Miller, Los Alamos National Laboratory ABSTRACT: In the extreme environments achievable in the core of a dying or dead star, nuclear reactions are of fundamental importance. Fusion of elements lighter than iron and the fission of unstable heavy isotopes are both deep reservoirs of energy. Moreover, understanding […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Samuel Shen, San Diego State University, Mathematics and Statistics ABSTRACT: iCHARM (Cyber Hub for Analytics, Research and Monitoring) is an interactive, AI-enabled data science system for visualizing, delivering, analyzing, and interpreting space-time data. It makes NOAA data in various space-time scales, from hourly to monthly and from grid […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Miguel Dumett, San Diego State University, Computational Science Research Center ABSTRACT: Given an Earth model and a macro velocity model, a subsurface reflectivity image is acquired through a migration process. Typical migration algorithms exhibit structures that are not well defined and/or with some artifacts due to a series […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Jianshu Liu, San Diego State University, Computer Science ABSTRACT: Scalability is an important feature of cloud computing, allowing web service providers to dynamically add or remove computing resources for their applications according to their needs. Efficiently scaling a cloud application to match workload is critical because the application […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Qi Wang, San Diego State University, Aerospace Engineering ABSTRACT: Turbulence governs fluid motion across a wide range of spatial and temporal scales, posing fundamental challenges for modeling, estimation, and control. Accurate reconstruction of turbulent flow states from limited observations is essential for both scientific understanding and engineering applications. […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Kathryn Maupin, Sandia National Laboratories ABSTRACT: As the third pillar of science, computational simulation has allowed scientists to explore, observe, and test physical regimes previously thought to be unattainable. High-fidelity models are derived from physical principles and calibrated to experimental data. However, missing or unknown physics and measurement, […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Gerhard Engel, Materials Design, Inc. ABSTRACT: Highly efficient software programs, unprecedented compute power, and intuitive multiscale modeling environments have made computational materials science an integral part of research and development. This talk will focus on how these powerful tools can be applied to industrially relevant problems in diverse […]
