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.

A framework for wheel profile wear prediction of high-speed trains considering tread modification

Friction
Tread modification has gained significant attention in recent years as a means to address the issue of wheel hollow wear. The wear resulting from tread modification can alter the wheel profile, thereby impacting the wheel–rail contact relationship and ...

Quantification of human‐caused mortality in an imperiled turtle

Wildlife Biology, EarlyView.
For many threatened and endangered species, the importance of human‐caused mortality relative to other sources has not been quantified, making it difficult to assess the effectiveness of mortality‐reduction strategies. We used radio telemetry data, pooled across studies at protected sites in the US states of Illinois and Wisconsin, to estimate natural ...

A nonlinear vehicle-structure interaction methodology with wheel-rail detachment and reattachment

, 2013
. A vehicle-structure interaction methodology with a nonlinear contact formulation based on contact and target elements has been developed. To solve the dynamic equations of motion, an incremental formulation has been used due to the nonlinear nature ...

Probabilistic simulation for the certification of railway vehicles [PDF]

, 2015
The present dynamic certification process that is based on experiments has been essentially built on the basis of experience. The introduction of simulation techniques into this process would be of great interest.
