    "The method and system for monitoring the structural health of offshore wind turbines" has been granted an invention patent certificate (Patent Number: ZL202610248475.5). 

    The present invention discloses a method and system for structural health monitoring of offshore wind turbines. The method comprises: in the offline stage, constructing a strain snapshot matrix through finite element simulation, extracting a low-dimensional feature subspace basis matrix by using proper orthogonal decomposition, and mapping the structural grid to a graph; Simultaneously, the Fourier feature mapping of node coordinates is carried out, and after concatenating with the reconstructed strain features, a spectral graph neural network based on Chebyshev graph convolution is trained. In the online monitoring stage, based on the real-time collected sparse strain data on one side, the modal coefficients are quickly solved through the mask matrix and the pre-stored basis matrix, and the full-field strain is preliminarily reconstructed. Then, it is input into the trained network model to real-time infer the high-fidelity full-field displacement and stress fields. This invention can effectively adapt to any changes in sensor layout and achieve real-time and accurate reconstruction of the full-field physical response of complex structures under the harsh condition of sparse measurement on one side, solving the problem of traditional techniques' dependence on fixed measurement points and bilateral measurement.

    Note: The inventors of this patent also include doctoral student Jiang Chunhao and postdoctoral fellow Li Yihong.

    The paper "ST-SRNet: A deep learning framework for seismic response prediction of subsea tunnels" has been published in Tunnelling and Underground Space Technology.

    As key infrastructure in nearshore and offshore areas, subsea tunnels face extremely high risks from earthquake disasters. Conventional numerical methods are computationally intensive, making them inadequate for real-time prediction demands under complex marine environments. To address this, this study proposes a rapid prediction method integrating high-fidelity finite element (FE) simulation and deep learning technology. A two-dimensional FE model incorporating bidirectional (horizontal and vertical) ground motions and hydrodynamic pressure effects is established to construct a comprehensive seismic response database. On this basis, the Subsea Tunnel Seismic Response Network (ST-SRNet) is developed, combining one-dimensional convolution, attention mechanisms, long short-term memory (LSTM), and a Feature-wise Linear Modulation (FiLM) module to achieve efficient and accurate prediction of seismic responses at multiple monitoring points. Results show that the model achieves high prediction accuracy, with the coefficient of determination values exceeding 0.95 and peak relative errors controlled below 10%, while also exhibiting strong generalization. An engineering case study further validates the robustness and applicability of the proposed method, providing effective technical support for disaster assessment, structural monitoring, and real-time early warning of subsea tunnels.

    The paper "Typhoon-Induced Risk Evolution in Wind Farms: From Disaster-Inducing Factors Identification to Domino Effect Assessment" has been published in the journal Reliability Engineering & System Safety. 

    In response to the technical accidents caused by typhoons in the complex waters of the South China Sea, this study proposes a Disaster-Inducing and Risk Evaluation (DIRE) framework. This framework integrates two modules: the Disaster Inducing Factor Extraction Model (DIFEM), which identifies the key environmental driving factors that cause damage to wind turbines through a hybrid physical-data fusion analysis; and the Hierarchical Analytical Domino Evaluation System (HADES), which realizes systematic hazard classification, hierarchical structuring, probability assessment, and consequence assessment. Through the analysis of five typhoon-induced disaster events in the South China Sea, this study not only identified the common and specific disaster-causing factors that cause damage to wind turbines, but also quantified the cascading disaster risks. The findings of this study provide reliable data and decision-making support for disaster prevention and mitigation on wind farms.

    Note: "Reliability Engineering & System Safety" is a top journal in the field of engineering technology in the Q1 zone, with an impact factor of 11.0 in 2025.

    The paper "Digital disaster prevention for ocean engineering: Current progress and future directions" has been published in the journal Ocean Engineering. 

    The increasing frequency of typhoons and other extreme climate events has intensified the risks of natural hazard-triggered technological accidents (Natech). Traditional disaster-prevention approaches, largely dependent on static analyses, are no longer sufficient for real-time risk identification or proactive mitigation in ocean engineering. This review synthesizes recent progress in digital disaster prevention, focusing on three core areas: disaster-inducing factor identification, disaster mechanism modeling, and structural safety assessment. The paper integrates physics-based numerical modeling, data-driven simulation, and system dynamics to analyze hazard triggers and cascading failures. It highlights applications of digital twins and deep learning in scenario-based risk analysis and early-warning systems, particularly for offshore wind farms. Furthermore, it proposes a forward-looking digital technology system that integrates environmental sensing, interpretable modelling, and resilience-oriented decision support. Overall, digital disaster prevention provides a significant pathway toward more adaptive, predictive, and resilient safety management in ocean engineering.

    Note: Ocean Engineering is a top journal in the field of engineering technology, classified in Q1, with an expected impact factor of 5.5 in 2025. I am the first author and corresponding author of the paper. The research was funded by the Shenzhen Science and Technology Program and the Guangdong Basic and Applied Basic Research Foundation.

    The paper titled “Dynamics-Based Adaptive Scheduling for Large-Scale Edge Computing Networks in Smart Cities” has been published in  IEEE Internet of Things Journal.

    Addressing the critical challenge of real-time and efficient task scheduling in large-scale distributed edge computing networks caused by the exponential growth of task requests from the rapid proliferation of IoT devices in smart cities, this paper proposes a novel Dynamics-based Adaptive Scheduling (DAS) method. By innovatively transforming the complex task scheduling problem into a two-dimensional geometric model and leveraging the principles of forward dynamics simulation, DAS achieves efficient and non-iterative task assignment, successfully reducing computational complexity to O(n log n). Simulation results demonstrate that the DAS method significantly outperforms existing benchmark strategies: it reduces service response time by 9% to 15%, improves system load balance by 93% to 98%, and decreases overall energy consumption by 2% to 12%. This solution effectively resolves scheduling efficiency and reliability issues in large-scale edge computing environments.

    Note: The IEEE Internet of Things Journal is a top journal in the field of engineering and technology, ranked in the Q1 zone, with an impact factor of 8.9 in 2025.
