Real world data is not stationary and thus models must be monitored in production. One way to be sure in a model’s performance is regular testing. If the labels are not available, the task of minimizing the labeling ...
An important limitation of existing adversarial attacks on real-world object detectors lies in their threat model: adversarial patch-based methods often produce suspicious images while image generation approaches do n...

This paper considers local scour around a pipeline under turbulent *** Navier-Stokes equations are solved with a shear stress turbulence *** original bed deformation equation based on an analytical sediment transport model is used to describe the changes in the bottom *** proposed sediment transport equation is based on Coulomb’s friction law for granular flow,Prandtl’s friction law for turbulent flow,and agrees with a large number of phenomenological formulas by other authors.A numerical algorithm for solving the mathematical model of bed surface erosion is implemented in *** simulations of the problem show that under the influence of turbulent flow generated at the pipeline streamline,a characteristic bottom wave of low steepness appears,the parameters of which asymptotically agree with the experimental *** on the analysis of experimental and numerical studies of the considered case,an assumption about the self-similar behavior of the bed surface evolution is *** on this assumption,a new method of constructing the self-similar dependence of the bed surface on time and space coordinates is *** the proposed approach,the average values of tangential bottom stresses are determined for a number of self-similar bottom surface shapes,and then the rates of change of bottom wave lengths and amplitudes are calculated using the proposed analytical model.A comparison with experimental data and numerical calculations shows that the solution error does not exceed a few percent and the computational time is reduced by up to 30 times.
One of the principle conditions of a wave attractor appearance is a periodic external forcing. Real forcing in natural basins caused by tidal interaction is more complex than a monochromatic which is usually used in i...
