Speaker: Dr. Tianzhen Hong, Lawrence Berkeley National Laboratory
Talk Title: Modeling Urban Buildings for Improvement of Efficiency and Resiliency
Abstract: U.S. cities consume 70% of primary energy, produces 80% of GDP, and are facing challenges of aging infrastructure, impact of climate change and extreme weather events. Urban systems are interconnected systems of buildings, microclimate, transportation, power and water supply. This talk will introduce urban systems research at the Building Technology and Urban Systems Division, focusing on modeling and simulation of urban buildings to improve their energy efficiency and resiliency, leveraging emerging opportunities in big data, artificial intelligence, and exascale computing.
Biography: Dr. Tianzhen Hong is a Staff Scientist and Deputy Head of the Building Technologies Department of Lawrence Berkeley National Laboratory. He leads the Urban Systems Group and a research team working on data analytics, modeling, simulation, and policy for design and operation of low energy buildings and sustainable urban systems. He is an IBPSA Fellow and an editor of the Energy and Buildings journal. He has more than 200 publications. He received B.Eng. and Ph.D. from Tsinghua University, China.

Talk Title: Machine Learning Enhanced Computational Mechanics: Reduced-Order Modeling and Physics-Informed Data-Driven Computing
Abstract:
Advances in the field of machine learning and the increasing availability of data from laboratory/field observations and high-fidelity simulation are quickly changing how the world solves important scientific problems. In this talk, I will present our research on developing integrative computational methods that leverage both physics-based models and data-centric techniques to address various challenges in computational mechanics related to civil, mechanical, and biological applications.
First, I will introduce physics-preserving reduced order schemes that employ simulation data and subspace projection to reduce computational cost while preserving critical physical properties in modeling fracture mechanics and thermal fatigue of electronic packages. Second, I will describe a manifold learning-based data-driven computing approach for modeling complex materials, where physics-based simulation proceeds interactively with the local data manifold reconstructed from experimental data,circumventing the limitations of using phenomenological constitutive models.
Finally, I will discuss our recent work in PNNL on developing machine learning framework based on deep neural networks for discovering hidden physics and modeling subsurface flow and transport in heterogenous porous media. The proposed approach allows the seamless fusion and integration of measurements from multiphysics systems and the information provided by the physical conservation laws, which regularize the neural networks as informative priors. The effectiveness of meshfree methods for these data-driven computing will also be demonstrated.
This work is supported by NSF, US Army Engineer Research, and the DOE ASCR.
Biography: Dr. Qizhi He is currently a Postdoctoral Research Associate in the Advanced Computing, Mathematics and Data Division at Pacific Northwest National Laboratory (PNNL). He obtained his B.S. in Engineering Mechanics from Wuhan University, M.S. in Computational Mechanics from Dalian University of Technology, and M.A. in Applied Mathematics and Ph.D. in Structural Engineering from the University of California, San Diego (UCSD). His research mainly focuses on the development of machine learning enhanced computational methods to model complex biological and civil systems and provide solutions to protect real-life structures from extreme hazardous events. His work combines the concepts from physics-based modeling, machine learning, and meshfree type approximation and discretization

Speaker: Dr. Shamin Pazkad, Lehigh University
Talk Title: Mobile Sensing Platform for Structural Monitoring
Abstract:
The rapid revolution in sensing, computation, and communication
technology in the past twenty years has provided exciting opportunities for the integration of sensing systems to contribute in addressing one of the key questions of the engineering community in realizing resilient systems. It is hard to imagine a future for resilient civil structures and
infrastructure without embedded interactive sensory networks that can provide comprehensive feedback about the condition of structures, and produce information that can be used in operation, maintenance,rehabilitation and functionality of structures and infrastructure. One of the new sources of data is through mobile sensing. The application of these sensing mechanisms in structural systems is the focus of this presentation.
