Large-scale wave-front reconstruction for adaptive optics systems by use of a recursive filtering algorithm [PDF]
, 2005 We propose a new recursive filtering algorithm for wave-front reconstruction in a large-scale adaptive optics system. An embedding step is used in this recursive filtering algorithm to permit fast methods to be used for wave-front reconstruction on an ...

Algebraic Domain Decomposition Methods for Highly Heterogeneous Problems [PDF]
, 2013 International audienceWe consider the solving of linear systems arising from porous media flow simulations with high heterogeneities. Using a Newton algorithm to handle the non-linearity leads to the solving of a sequence of linear systems with different

Asynchronous Iterations of Parareal Algorithm for Option Pricing Models
Mathematics, 2018 Spatial domain decomposition methods have been largely investigated in the last decades, while time domain decomposition seems to be contrary to intuition and so is not as popular as the former.

Isogeometric Simulation and Shape Optimization with Applications to Electrical Machines [PDF]
, 2018 Future e-mobility calls for efficient electrical machines. For different areas of operation, these machines have to satisfy certain desired properties that often depend on their design. Here we investigate the use of multipatch Isogeometric Analysis (IgA)

A Fault Feature Extraction Method of Motor Bearing Using Improved LCD
IEEE Access, 2020 Local characteristic-scale decomposition (LCD) is an adaptive decomposition method for non-stationary and nonlinear time-varying signals. In this paper, kernel mapping is used to replace random mapping in LCD, and a fault feature extraction method based ...

The Analytical Methods Of Volterra Integral Equations of The Second Kind
Wasit Journal of Computer and Mathematics Science, 2023 This paper discussed the analytic methods to solve Second order Volterra integral equations form using different methods. The domain decomposition method is the first technique. Depending on the hypothesis, the solution is by sequence. The second method
