Talk Title: Robust Autonomous Vehicle Localization using GPS: from Tandem Drifting Cars to GPS on the Moon
Abstract: Autonomous vehicles often operate in complex environments with various sensing uncertainties. On Earth, GPS signals can be blocked or reflected by buildings; and camera measurements are susceptible to lighting conditions. While having a variety of sensors is beneficial, including more sensing information can introduce more sensing failures as well as more computational load. For space applications, such as localization on the Moon, it can be even more challenging. In this talk, I will present our recent research efforts on robust vehicle localization under sensing uncertainties. We turn sensing noise and even absence of sensing into useful navigational signals. Inspired by cognitive attention in humans, we select a subset of “attention landmarks” from sensing measurements to reduce computation load and provide robust positioning. I will also show our localization techniques that enable various applications, from autonomous tandem drifting cars to a GPS-like system for the Moon.

Talk Title: Enabling Sustainable Propulsion and Clean Energy Transitions: Reacting Flow Modeling across molecular to continuum scales
Abstract: While the global demand for air travel continues to rise, the aerospace carbon footprint is increasingly concerning. In the near term, it is highly desirable for the rational design, efficient certification, and massive production of carbon-neutral fuels to mitigate greenhouse emissions. Furthermore, future aerospace vehicles will be integrated with highly efficient and high-speed propulsion devices using clean and renewable energy sources. The design of these sustainable and high-speed propulsion systems requires a fundamental understanding of reacting flow physics across multiple scales, featuring interactions between the molecular and the continuum flow scale.
In this talk, I will present state-of-the-art approaches to multiscale reacting flow modeling of sustainable aerospace energy carriers. The modeling spans from molecular scale using GPU-enabled quantum chemistry computation to continuum scale gas dynamics and turbulence-resolved flow modeling. I will first emphasize the reacting flow modeling of bio-derived sustainable aviation fuel (SAF), which is considered a near-term alternative to conventional jet fuels. I will then discuss the study of methane and natural gas as potential transition fuels, along with hydrogen and battery technologies for the long-term future. I envision that the presented approach will help not only to enable sustainable aviation but also to advance a clean and sustainable transition in the future energy landscape.
Biography: Rui (Ray) Xu is a Postdoctoral Scholar in the Department of Chemistry at Stanford University and the PULSE Institute in the SLAC National Accelerator Laboratory. His research centers around multiscale reacting flow modeling to enable sustainable aerospace propulsion and clean energy transitions. Dr. Xu obtained his Ph.D. in Mechanical Engineering from Stanford University, his M.S. in Mechanical Engineering from Northwestern University, and his B.S. in Mechanical Engineering from Shanghai Jiao Tong University. He is the recipient of the ACS Wiley Computers in Chemistry Outstanding Postdoc Award in 2024 and the ACTC AFOSR Scholar Award in 2022.
