Electro-Hydrodynamic Shooting Phenomenon of Liquid Metal Stream [PDF]
, 2014 We reported an electro-hydrodynamic shooting phenomenon of liquid metal stream. A small voltage direct current electric field would induce ejection of liquid metal inside capillary tube and then shooting into sodium hydroxide solution to form discrete droplets.

A Rule-Based Model for Victim Prediction [PDF]
, 2020 In this paper, we proposed a novel automated model, called Vulnerability Index for Population at Risk (VIPAR) scores, to identify rare populations for their future shooting victimizations. Likewise, the focused deterrence approach identifies vulnerable individuals and offers certain types of treatments (e.g., outreach services) to prevent violence in ...

Hierarchical Reinforcement Learning for Precise Soccer Shooting Skills using a Quadrupedal Robot [PDF]
arXiv, 2022 We address the problem of enabling quadrupedal robots to perform precise shooting skills in the real world using reinforcement learning. Developing algorithms to enable a legged robot to shoot a soccer ball to a given target is a challenging problem that combines robot motion control and planning into one task.
