Online randomized interpolative decomposition with a posteriori error estimator for temporal PDE data reduction
Angran Li, Stephen Becker, Alireza Doostan
Traditional low-rank approximation is a powerful tool to compress the huge data matrices that arise in simulations of partial differential equations (PDE), but suffers from high co…
Modeling material transport regulation and traffic jam in neurons using PDE-constrained optimization
Angran Li, Yongjie Jessica Zhang
The intracellular transport process plays an important role in delivering essential materials throughout branched geometries of neurons for their survival and function. Many neurod…
Composing Open-domain Vision with RAG for Ocean Monitoring and Conservation
Sepand Dyanatkar, Angran Li, Alexander Dungate
Climate change's destruction of marine biodiversity is threatening communities and economies around the world which rely on healthy oceans for their livelihoods. The challenge of a…
HexGen and Hex2Spline: Polycube-based Hexahedral Mesh Generation and Spline Modeling for Isogeometric Analysis Applications in LS-DYNA
Yuxuan Yu, Xiaodong Wei, Angran Li +3
In this paper, we present two software packages, HexGen and Hex2Spline, that seamlessly integrate geometry design with isogeometric analysis (IGA) in LS-DYNA. Given a boundary repr…
Deep learning of material transport in complex neurite networks
Angran Li, Amir Barati Farimani, Yongjie Jessica Zhang
Neurons exhibit complex geometry in their branched networks of neurites which is essential to the function of individual neuron but also brings challenges to transport a wide varie…
