Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Structural Concrete, EarlyView.Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Quantifying and Tracking Flexibility of System Elements to Support (Re)Design Decision‐Making
Systems Engineering, EarlyView.ABSTRACT Evolving objectives and requirements, risk management processes, and external disruptions frequently drive change in engineered systems. Due to these pressures, system architects must anticipate and manage change throughout a system's lifecycle. Yet, managing change is challenging due to the risk of change propagation.

Do the public take action when a severe snow warning is issued?
Weather, EarlyView.Extreme weather events pose significant risks to the population, making timely warnings essential for preparedness. The UK Met Office’s National Severe Weather Warning Service (NSWWS) has issued impact‐based alerts for over a decade, yet evaluations of their effectiveness remain limited.

The winter 2023/2024 floods in the UK: a hydrological appraisal
Weather, EarlyView.From October 2023 to March 2024, the UK saw a succession of named storms and low‐pressure weather systems, leading to widespread exceptional river flows throughout. Peak flow records were broken in several catchments, but this event was most notable for its duration and spatial footprint, which resulted in major impacts.

Ungulate substrate use in fauna passages
Wildlife Biology, EarlyView.Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Wildlife Society Bulletin, EarlyView.Autonomous recording units (ARUs) are increasingly used for passive acoustic monitoring, but deploying them in remote or inaccessible locations remains challenging. We developed and field‐tested a lightweight, low‐cost floating platform for drone‐assisted deployment and retrieval of ARUs in wetland interiors.

High Voltage, EarlyView.ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

High Voltage, EarlyView.ABSTRACT The synergistic effect of airflow on rainfall behaviour significantly impacts the flashover probability of insulators. This study combines experiments and simulations to investigate the influence of raindrop dynamic behaviour, shed structures and rainfall conditions on flashover characteristics under airflow conditions.
