A study on fault diagnosis in nonlinear dynamic systems with uncertainties
Steven X. Ding, Linlin Li
In this draft, fault diagnosis in nonlinear dynamic systems is addressed. The objective of this work is to establish a framework, in which not only model-based but also data-driven…
PINN-based viscosity solution of HJB equation
Tianyu Liu, Steven Ding, Jiarui Zhang +1
This paper proposed a novel PINN-based viscosity solution for HJB equations. Although there exists work using PINN to solve HJB, but none of them gives the solution in viscosity se…
Replay Attack Detection Based on Parity Space Method for Cyber-Physical Systems
Dong Zhao, Yang Shi, Steven X. Ding +2
The replay attack detection problem is studied from a new perspective based on parity space method in this paper. The proposed detection methods have the ability to distinguish sys…
Understanding the Time to First Response In GitHub Pull Requests
Kazi Amit Hasan, Marcos Macedo, Yuan Tian +2
The pull-based development is widely adopted in modern open-source software (OSS) projects, where developers propose changes to the codebase by submitting a pull request (PR). Howe…
