Propagation graph estimation from individuals’ time series of observed states

Scientific Reports, 2022
Various things propagate through the medium of individuals. Some individuals follow the others and take the states similar to their states a small number of time steps later.

Research corrosion propagation time of reinforced concrete structures considering load influence [PDF]

Archives of Civil Engineering, 2022
Prediction of propagation time of corrosion is a key element in evaluating the service life of corroded reinforced concrete (RC) structures. Corroded steel products often expand in volume and thus generate tensile stress in the concrete cover.

An alternative implementation of the Lanczos algorithm for wave function propagation [PDF]

, 2006
We reformulate the Lanczos algorithm for quantum wave function propagation in terms of variational principle. By including some basis states of previous time steps into the variational subspace, the resultant accuracy increases by several orders ...

Gluon propagation in space-time dependent fields

, 2004
The propagator for gluons in a space-time dependent field is derived. This is accomplished by solving the equation of motion for the gluonic Green's functions. Subsequently a relationship between the quark and the gluon propagator is presented.

A Parametric Study on Determining the Corrosion Initiation and Propagation Times of Reinforced Concrete Structures Using Different Methods

Buildings
Reinforced concrete structures deteriorate over time when exposed to environmental effects throughout their service life, resulting in a loss of structural performance and ultimately a reduction in service life.
