Effect of Dynamic Loads on the Long-Term Efficiency of Liner Layers

open access: yesBuildings, 2023
The liner layers of natural sand-clay mixtures are extensively used in a range of geotechnical and geoenvironmental projects. In many of these projects, these layers are exposed to dynamic loads or waves due to natural seismic earthquakes or due to human

Mechanistic–Empirical Analysis of Pavement Performance Considering Dynamic Axle Load Spectra Due to Longitudinal Unevenness

open access: yesApplied Sciences, 2022
Pavement distresses are induced by mechanistic responses in pavement structure subjected to dynamic loads of moving vehicles. Pavement surface evenness deteriorates as pavement distresses propagate, which results in dynamic axle loads and faster pavement

Analytical solution to approximate equations of the launch vehicle motion under the gust action for the dynamic loading calculation

open access: yesAdvanced Engineering Research, 2022
Introduction. The launch vehicle (LV) in flight and the dynamic components of loads from the impact of a trapezoidal wind gust are considered. It is proposed to determine the dynamic components of the force factors using analytical solutions for the ...

Dynamic Diffusion Load Balancing [PDF]

open access: yes, 2005
We consider the problem of dynamic load balancing in arbitrary (connected) networks on n nodes. Our load generation model is such that during each round, n tasks are generated on arbitrary nodes, and then (possibly after some balancing) one task is deleted from every non-empty node. Notice that this model fully saturates the resources of the network in
