On numerical approximation schemes for expectation propagation

CoRR, 2016
Several numerical approximation strategies for the expectation-propagation algorithm are studied in the context of large-scale learning: the Laplace method, a faster variant of it, Gaussian quadrature, and a deterministic version of variational sampling (i.e., combining quadrature with variational approximation).

Dynamic contact of two Gao beams

Electronic Journal of Differential Equations, 2012
The dynamic contact of two nonlinear Gao beams that are connected with a joint is modeled, analyzed, and numerically simulated. Contact is modeled with either (i) the normal compliance condition, or (ii) the unilateral Signorini condition.

Dynamic contact of viscoelastic bodies with two obstacles: mathematical and numerical approaches

Electronic Journal of Differential Equations, 2013
The motion of viscoelastic (Kelvin-Voigt model) bodies between an upper and a lower obstacle is studied both mathematically and numerically. The two obstacles are assumed to be stationary perfect rigid, therefore, Signorini contact conditions are ...

Semi-Implicit Numerical Models of Flood Hydraulic Routing (A Case Study: Lighvan-Hervi Reach of Lighvan-Chai, Tabriz)

علوم آب و خاک, 2018
River flow routing has been a significant issue in hydraulic engineering. The main goal of this research work was solving Saint-Venant equations by using the semi-implicit finite difference scheme and considering energy conservation principle at the ...
