Characteristic dynamic traffic load effects in bridges [PDF]

open access: yes, 2009
When formulating an approach to assess bridge traffic loading with allowance for Vehicle-Bridge Interaction (VBI), a trade-off is necessary between the limited accuracy and computational demands of numerical models and the limited time periods for which ...

LIDAR-Assisted Wind Turbine Structural Load Reduction by Linear Single Model Predictive Control

open access: yesIEEE Access, 2020
LIght Detection And Ranging (LIDAR) sensors provide preview measurements of wind speed in front of the device. This preview may be used to improve important aspects of the operation of wind turbines, such as structural load, while limiting the control ...

The effect of military load carriage on ground reaction forces [PDF]

open access: yes, 2007
Load carriage is an inevitable part of military life both during training and operations. Loads carried are frequently as high as 60% bodyweight, and this increases injury risk. In the military, load is carried in a backpack (also referred to as a Bergen)
