A 22n March Test for Realistic Static Linked Faults in SRAMs [PDF]
, 2006 Linked faults are considered an interesting class of memory faults. Their capability of influencing the behavior of other faults causes the hiding of the fault effect and makes test algorithm design a very complex task.

Self healing control method against unmanned helicopter actuator stuck faults
, 2014 A self healing (SH) control framework is proposed in this paper against actuator stuck faults. For unmanned helicopters (UHs), the framework is composed by an active fault-tolerant control (FTC) system and reference redesign.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Fault detection and isolation of actuator failures for a large transport aircraft [PDF]
, 2007 - We consider the problem of designing residual generators with least dynamical orders to solve actuator fault detection and isolation problems for a Boeing 747-100/200 aircraft. The main result of our analysis is the proof of feasibility of the complete
