Generalization of anomaly detection in bridge structures using a vibration‐based Siamese convolutional neural network

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 18, Page 2751-2768, 18 July 2025.
Abstract Corrosion is one of the main damages in steel bridges, which appears as a loss of material and sectional area and causes member failure over time. A reliable bridge management system not only should help in preventing catastrophic structural failure by employing an in‐time anomaly detection approach for all the bridges within a network but ...

Probiotic‐Based Approaches for Sustainable Control of Infectious Risk in Mass Transport: Current Data and Future Perspectives

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
High‐traffic areas, such as mass transportation environments, can have a significant impact on infection transmission, and chemical disinfection may favour the selection of drug‐resistant microbes. Probiotic‐based approaches have the potential to be a novel and ecologically sustainable option for controlling bioburden and preventing infections ...

Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]

, 2015
Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

A direct method for analyzing the vertical vehicle-structure interaction [PDF]

, 2011
A new method for the dynamic analysis of the vertical vehicle-structure interaction is presented. The vehicle and structure systems can be discretized with various types of finite elements and may have any degree of complexity.

Classification of direct threats to the conservation of ecosystems and species 4.0

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Identifying and assessing the magnitude of direct threats to ecosystems and species are critical steps to prioritizing, planning, implementing, and assessing conservation actions. Just as medical clinicians and researchers need a standard way to talk about human diseases, conservation practitioners and scientists need a common and ...

A multilevel track defects assessment framework based on vehicle body vibration

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 12, Page 1688-1720, 9 May 2025.
Abstract High‐frequency detection of track defects is crucial for accurate track condition assessment and system safety. Onboard vibration data collection devices can significantly increase detection density without additional costs. However, defect assessment based on this is significantly challenging, including the spatial heterogeneity of track ...

Case study: The downside of using a worst‐case approach in occupational safety policy as an interpretation of the precautionary principle: Putting the uncertain UXO occupational safety risk into probabilistic perspective

Risk Analysis, Volume 45, Issue 5, Page 973-980, May 2025.
Abstract Unexploded ordnance (UXO) from the World Wars on the North Sea floor pose an uncertain occupational safety risk for dredging and cable installation. At present mitigation strategies are based on an interpretation of the precautionary principle that uses a worst‐case approach, that is, assuming that UXO will be encountered, will explode, and ...
