Variable Step-size Implicit-explicit Linear Multistep Methods for Time-dependent Partial Differential Equations
Implicit-explicit (IMEX) linear multistep methods are popular techniques for solving partial differential equations (PDEs) with terms of different types. While fixed timestep versions of such schemes have been developed and studied, implicit-explicit schemes also naturally arise in general situations where the temporal smoothness of the solution changes. In this paper we consider easily impleme...
متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
متن کاملVariable time step integration
Symplectic methods for Hamiltonian systems are known to have favourable properties concerning long-time integrations (no secular terms in the error of the energy integral, linear error growth in the angle variables instead of quadratic growth, correct qualitative behaviour) if they are applied with constant step sizes, while all of these properties are lost in a standard variable step size impl...
متن کاملVariable step search algorithm for feedforward networks
A new class of search-based training algorithms for feedforward networks is introduced. These algorithms do not calculate analytical gradients and do not use stochastic or genetic search techniques. The forward step is performed to calculate error in response to localized weight changes using systematic search techniques. One of the simplest variants of this type of algorithms, the Variable Ste...
