Feature Pyramid and Hierarchical Boosting Network for Pavement Crack Detection [PDF]

open access: yesIEEE transactions on intelligent transportation systems (Print), 2019
Pavement crack detection is a critical task for insuring road safety. Manual crack detection is extremely time-consuming. Therefore, an automatic road crack detection method is required to boost this progress.

Automatic crack classification and segmentation on masonry surfaces using convolutional neural networks and transfer learning

open access: yesAutomation in Construction, 2021
Masonry structures represent the highest proportion of building stock worldwide. Currently, the structural condition of such structures is predominantly manually inspected which is a laborious, costly and subjective process. With developments in computer

Road Crack Detection Using Deep Convolutional Neural Network and Adaptive Thresholding [PDF]

open access: yes2019 IEEE Intelligent Vehicles Symposium (IV), 2019
Crack is one of the most common road distresses which may pose road safety hazards. Generally, crack detection is performed by either certified inspectors or structural engineers. This task is, however, time-consuming, subjective and labor-intensive.

An Evolutionary Strategy for Spawning Habitat Selection by Pseudopungtungia tenuicorpa

open access: yesAnimals, 2023
In this study, we hypothesized that the limited geographical distribution of Pseudopungtungia tenuicorpa in South Korea is closely related to the local abundance of their preferred spawning habitats. Eggs of P. tenuicorpa were most frequently observed in

Crack-Growth Behavior in Thermal Barrier Coatings with Cyclic Thermal Exposure [PDF]

open access: yes, 2019
Crack-growth behavior in yttria-stabilized zirconia-based thermal barrier coatings (TBCs) is investigated through a cyclic thermal fatigue (CTF) test to understand TBCs’ failure mechanisms.
