On top of machine learning (ML) models, uncertainty quantification (UQ) functions as an essential layer of safety assurance that could lead to more principled decision making by enabling sound risk assessment and management. The safety and reliability improvement of ML models empowered by UQ has the potential to significantly facilitate the broad adoption of Read more…
The use of unmanned aerial vehicles (UAVs) for structural health inspection has become a promising technique to perform labor-intensive, accessibility-challenged, and sometimes dangerous inspection tasks. This paper presents a novel physics-informed UAV inspection planning framework for infrastructure structural health assessment based on model-based diagnostics and prognostics enabled by physics-based probabilistic analysis. It Read more…
Path planning plays a vital role in ensuring the efficient and safe operation of off-road autonomous ground vehicles (AGVs). Current methods mostly focus on minimizing the travel time or path length of AGVs and often overlook the fact that the AGVs could fail in many ways during the operation due Read more…
Likelihood-free inference methods have been widely adopted, but they face significant challenges in updating multi-level computational models that have hierarchically embedded sub-models. This difficulty arises from the lack of direct observations of the quantities of interest of the sub-models. In addition, recent advancements in sensing and image processing technologies allow Read more…
Dr. Zhen Hu has been awarded the ASME Design Automation Young Investigator Award. The award was presented during ASME’s 2023 International Design Engineering Technical Conference (IDETC). The Design Automation Young Investigator Award is given from time to time, but never more than once each year, to recognize an outstanding young investigator who is making noteworthy contributions in Read more…
Reliability-based global path planning incorporates reliability constraints into path planning to ensure that off-road autonomous ground vehicles can operate reliably in uncertain off-road environments. Current two-stage reliability-based path planning methods involve separate stages for surrogate modeling of mobility prediction and global path planning, resulting in a large number of unnecessary Read more…
