Affine Body Dynamics: Fast, Stable & Intersection-free Simulation of Stiff Materials
Lei Lan, Danny M. Kaufman, Minchen Li +2
Simulating stiff materials in applications where deformations are either not significant or can safely be ignored is a pivotal task across fields. Rigid body modeling has thus long…
High-order Differentiable Autoencoder for Nonlinear Model Reduction
Siyuan Shen, Yang Yin, Tianjia Shao +4
This paper provides a new avenue for exploiting deep neural networks to improve physics-based simulation. Specifically, we integrate the classic Lagrangian mechanics with a deep au…
Neptune's resonances in the Scattered Disk
Lei Lan, Renu Malhotra
The Scattered Disk Objects (SDOs) are thought to be a small fraction of the ancient population of leftover planetesimals in the outer solar system that were gravitationally scatter…
Neptune's 5:2 Resonance in the Kuiper Belt
Renu Malhotra, Lei Lan, Kathryn Volk +1
Observations of Kuiper belt objects (KBOs) in Neptune's 5:2 resonance present two puzzles: this third order resonance hosts a surprisingly large population, comparable to the promi…
Debris Engine: A Potential Thruster for Space Debris Removal
Lei Lan, Jingyang Li, Hexi Baoyin
We present a design concept for a space engine that can continuously remove the orbit debris by using the debris as a propellant. Space robotic cleaner is adopted to capture the ta…
