Recently, our research group's paper titled "BIM-based integrated delivery technologies for intelligent MEP management in the operation and maintenance phase," published in the journal Advances in Engineering Software, has reached 300 citations on Google Scholar.

The sustained attention this work has received from both domestic and international peers can be attributed to its effective response to critical challenges in the operation and maintenance (O&M) phase of building lifecycle. In response to the common difficulties caused by inconvenient access to traditional completion documents and incomplete information delivery, which hinder intelligent management, our research focused on the urgent task of "information digitalization." We explored ways to enable the as-built model to truly embed the key information required for intelligent O&M management, striving to establish a complete research loop from "data integration" to "system implementation."

Validation through real-world engineering cases demonstrated that the proposed solutions effectively support intelligent MEP management and ensure the operational safety of the systems. The cumulative citation count, to some extent, reflects the practical value of this research in advancing the digital transformation of the construction industry. Looking ahead, we will continue to deepen our research and further explore the integration and application of BIM technology across the full building lifecycle, providing more solid technical support for the intelligent and digital development of China's construction industry.

The paper entitled “Precise longitudinal crack detection via continuous texture reconstruction and deep segmentation” has been published in Advanced Engineering Informatics.

Pavement cracks are a major form of road infrastructure degradation, necessitating efficient and accurate detection for timely maintenance. Existing inspection methods rely either on labor-intensive manual surveys or automated systems constrained by high hardware costs and GPS dependency, which limits their flexibility for continuous surface assessment. To address these limitations, this paper introduces a dual-channel crack detection model that integrates continuous pavement texture reconstruction with deep segmentation and high-precision boundary refinement algorithms, enabling on-site implementation and accuracy enhancement for longitudinal crack detection. A feature-based image stitching algorithm is developed to reconstruct continuous pavement textures from high-resolution images, enabling GPS-free crack localization. The proposed method further combines the YOLOv8-seg model with adaptive morphological operations to achieve pixel-level crack reconstruction. Comparative experiments reveal that the hybrid approach achieves superior segmentation performance, with finer boundary delineation and improved branch recovery compared to the baseline model. This paper provides a practical solution for automated inspection and high-fidelity reconstruction of longitudinal cracks, effectively supporting pavement maintenance planning.

The paper entitled “Numerical investigation of elliptical ribbed manifold microchannel heat sink and multi-objective optimization utilizing machine learning” has been published in Thermal Science and Engineering Progress.

This study addresses the thermal management challenges associated with high-heat-flux chips by focusing on the flow and heat transfer characteristics, as well as structural optimization, of an elliptical ribbed manifold microchannel heat sink (MMCHS). In response to the insufficient understanding of how microchannel height, microchannel width, elliptical rib dimensions, and coolant volumetric flow rate affect pressure drop and heat dissipation performance, extensive numerical simulations were conducted. The study systematically investigated the effects of different channel geometries, rib configurations, and volumetric flow rates on the coupled flow and heat transfer behavior within the elliptical ribbed MMCHS. The results revealed the variation patterns of cooling performance, pressure drop, Nusselt number, friction factor, and thermal enhancement efficiency under different design parameters, and further clarified the underlying mechanisms governing these performance metrics and the associated thermal irreversibility. On this basis, a high-accuracy artificial neural network model was developed to predict the substrate bottom temperature and pressure drop. By integrating the artificial neural network with a genetic algorithm, multi-objective optimization was performed to obtain a Pareto front that simultaneously minimizes substrate bottom temperature and pressure drop. The results show that the optimized design can achieve a 1.36%–3.75% improvement in thermal enhancement efficiency within a lower Reynolds number range, providing valuable engineering guidance for chip thermal management under pumping-power-limited conditions.
