Intermittent Failures in Hardware and Software
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intermittent failures and no fault found (NFF) phenomena are a concern in electronic systems because of their unpredictable nature and irregular occurrence. They can impose significant costs for companies, damage the ...
Lithium-Ion Battery Strain Gauge Monitoring and Depth of Discharge Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lithium-ion battery diagnostics and prognostics rely on measurements of electrical impedance, capacity, and voltage to infer the internal state of the battery. Mechanical changes to the cell structure represent an additional ...
Sparse Identification of Nonlinear Dynamics-Based Feature Extraction for Data Driven Model Predictive Control of a Buck Boost Switch Mode Power Supply
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents two methods of creating model predictive control (MPC) strategies for efficient real-time control algorithms for power electronics. Two novel methods of performing nonlinear modeling are presented in ...
Daily Engine Performance Trending Using Common Flight Regime Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate flight regime identification is critical for enhancing aircraft efficiency and safety. Traditionally, predictive models for aircraft operation have relied on complex, black-box machine learning techniques that ...
Balancing Interpretability and Uncertainty in Prognostic Models: A TOPSIS-Based Comparative Analysis of N-CMAPSS DS02 Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prognostic models are vital for predictive maintenance, enabling accurate prediction of remaining useful life (RUL) in complex systems. However, balancing model interpretability, accuracy, and robust uncertainty quantification ...
