[Title] Engineering-Driven Data Analytics for System Informatics

Engineering-driven data analytics focuses on developing new methodologies for system-level fusion of data-driven models and physical models in order to realize real-time monitoring of system operations, accurate detection of system faults, quick diagnosis of root causes, predictive control and process optimization. In this presentation, three research examples will be covered: (1) High-dimension nonlinear data are commonly encountered in many complex engineering systems. A penalized mixed-effects decomposition (PMD) method was proposed to decompose high-dimensional functional data into different components. The extracted features can represent corresponding quality characteristics in the scalable nanomanufacturing process. (2) Dimensional shape control of composite parts is vital for large-scale production and integration of composite structures. An automated shape control system was proposed to adjust composite parts to an optimal configuration in an effective and efficient manner. (3) A physics-driven deep learning architecture, “StressNet” was developed to predict the maximum stress in fracture propagation of brittle materials. The proposed methods are formulated into a systematic data decomposition framework and it will be briefly discussed.
