Abstract:

Analysis and modeling of the large-scale high-dimensional streaming data is a very important and challenging problem. This talk focuses on modeling the high-dimensional data obtained from sensors for assessment of system performance, early detection of system anomalies, intelligent sampling and sensing for data collection and decision making to achieve optimal system performance. The developed methodology is efficient and scalable and can be applied for data with complex heterogeneous data structure to extract information or useful features. The talk will discuss six interrelated topics: (i) detect anomalies from high-dimensional image data by using smooth sparse decomposition (SSD), which exploits regularized high-dimensional regression to decompose an image and separate anomalous regions by solving a large-scale optimization problem; (ii) introduce spatial-temporal smooth sparse decomposition (ST-SSD) method for dimension reduction, denoising, and anomaly detection of high dimensional streaming video data; (iii) adaptive sampling for high-dimensional functional data to speed up the inspection and anomaly detection through an intelligent sequential sampling scheme integrated with fast estimation and detection. (iv) dynamic multivariate functional data modeling via sparse subspace learning to achieve automatic data segmentation and grouping for high-dimensional functional data with complex cross-correlation structure. (v) Engineering-driven data analytics for monitoring of multiple functional data, where in-situ Roman sensing data are used to monitoring nanomanufactuirng processes. (vi) A data-level fusion model for developing composite health indices for degradation modeling and prognostic analysis. All those topics presented involve new methodologies development motivated with real engineering problems and validated with real industrial data sets.

Recent Development and Challenges in Real-Time Machinery Health Condition Monitoring

Dr. Wilson Wang, Fellow of International Society of Engineering Asset Management
Professor, Lakehead University, Canada

 

Abstract:

Reliable online machinery health condition monitoring has become a critical issue in both academic research and industrial applications. Diagnostic information can be used to recognize machinery defect at its earliest stage, so as to prevent machinery performance degradation and malfunction, and improve its operation accuracy and safety. Prognostic information can be applied to estimate the remaining useful life of the faulty component/unit, to properly schedule predictive maintenance operations without unnecessary downtimes so as to reduce costs. In this speech, the related new development and remaining challenges will be discussed in the main areas of real-time machinery health condition monitoring, such as smart sensor networks for data acquisition, signal processing for robust representative feature extraction, and AI-based automatic diagnostics and prognostics. Some issues in implementing a smart monitor for real-time industrial applications in common machinery systems such as pumps, induction motors and gearboxes will also be discussed.

Abstract:

With the change of the modern war pattern and innovation of technology, the missile weapon system develops towards the direction of high performance, high reliability and strong survivability. The demands for the optimal overall performance of the missile is ever-increasing. This talk focuses on the application of the uncertainty-based design optimization methodology to the missile overall design in order to solve the difficulties in the new missile development. The talk will discuss four interrelated topics: (i) identify the significant uncertainty parameters greatly impacting on the system response by the max-min distance sequential sampling method, which is combined with the characteristics of missile overall parameter uncertainties on the basis of the Latin hypersonic sample pool; (ii) introduce the improved active learning Kriging reliability analysis method and threshold reliability analysis method to deal with the nonlinear reliability problem and inverse reliability problem respectively, which can significantly enhance the efficiency of the uncertainty analysis in the missile overall design; (iii) present a new uncertainty-based design optimization method based on the margin quantification decoupling strategy, which can improve the efficiency of the missile overall design optimization; (iv) introduce the study of a boost-glide missile overall design, in which the disciplinary models and the corresponding uncertainty models are constructed. The proposed uncertainty-based design optimization method is also employed in this study to achieve the optimal missile overall design. Above topics involving new approaches are demonstrated by the engineering practice.

A Sampled-Data Approach to Analysing Complex Networks

Dr. Zidong Wang, Fellow of IEEE
Professor, Brunel University London, UK
 

 

Abstract:

In this talk, we will address the sampled-data synchronization control problem for a class of general complex networks, and then deal with the sampled-data filtering problems for two special classes of complex networks – wireless sensor networks and genetic regulatory networks. The sampling period considered here is time-varying that is allowed to switch between two different values in a random way. The main purpose is to deliver the message that sampled-data issue is vitally important for the applications of complex network theory and the sampled-data filtering/control problems are interesting yet challenging. Both the theoretical research and engineering applications will be discussed, and a series of recently published results will be reported.
