Estimation and Prediction of Vertical Deformations of Random Surfaces, Applying the Total Least Squares Collocation Method [PDF]
Sensors, 2020 This paper proposes a method for determining the vertical deformations treated as random fields. It is assumed that the monitored surfaces are subject not only to deterministic deformations, but also to random fluctuations.
