Seismic barriers: theory and numerical simulations [PDF]
E3S Web of Conferences, 2019 The basic idea of a seismic barrier is to protect an area occupied by a building or a group of buildings from seismic waves. Depending on the nature of seismic waves that are the most probable in a specific region, different kinds of seismic barriers are

The Numerical Simulation in Ballistics
Nonlinear Analysis: Modelling and Control, 2001 In this paper we examine the movement of the solid body thrown with some angle to the horizon (for example the shot mine). Such movement is described by non-linear system of equations. This system is being approximated by linear system, in segments. The experiment results have been approximated and the dependence of air resistance coefficient from mean

Numerical simulation of Faraday waves [PDF]
Journal of Fluid Mechanics, 2009 We simulate numerically the full dynamics of Faraday waves in three dimensions for two incompressible and immiscible viscous fluids. The Navier–Stokes equations are solved using a finite-difference projection method coupled with a front-tracking method for the interface between the two fluids.

Numerical Simulations of Spin Glass Systems [PDF]
, 1997 We discuss the status of Monte Carlo simulations of (mainly finite dimensional) spin glass systems. After a short historical note and a brief theoretical introduction we start by discussing the (crucial) 3D case: the warm phase, the critical point and ...

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

A Review of Laboratory and Numerical Techniques to Simulate Turbulent Flows
Energies, 2022 Turbulence is still an unsolved issue with enormous implications in several fields, from the turbulent wakes on moving objects to the accumulation of heat in the built environment or the optimization of the performances of heat exchangers or mixers. This

Numerical Dynamo Simulations [PDF]
, 2007 In this chapter, we review the progress in numerical modeling of the geodynamo made since 1995. Modern geodynamo models solve the fundamental equations of convection-driven flow and magnetic induction in a rotating spherical shell filled with an electrically conducting fluid.

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...
