WebSummary Imaging the subsurface attenuation models using wave equation based tomography methods is an important and challenging task. The forward modeling of wave propagation in anelastic media can be considered as solved based on superposition of rheological bodies with the generalized standard linear solid model. However, in … The standard linear solid (SLS), also known as the Zener model, is a method of modeling the behavior of a viscoelastic material using a linear combination of springs and dashpots to represent elastic and viscous components, respectively. Often, the simpler Maxwell model and the Kelvin–Voigt model are used. These models often prove insufficient, however; the Maxwell model does not describe creep or recovery, and the Kelvin–Voigt model does not describe stress relax… Webincluding generalized linear and generalized mixed-effect models, as well as models allowing for mixtures, spatial or phylogenetic correlations, missing or censored data, and observational data; implemented in R and set within a contemporary research framework.
