Domain decomposition for multiscale PDEs [PDF]

Numerische Mathematik, 2007
The authors consider additive Schwarz domain decomposition preconditioners for piecewise linear finite element approximations of elliptic partial differential equations with highly variable coefficients. These preconditioners combine local solvers on general overlapping subdomains together with a global solver on a general coarse space of functions on ...

Efficient 3D Frequency Semi-Airborne Electromagnetic Modeling Based on Domain Decomposition

Remote Sensing, 2023
Landslides are common geological hazards that often result in significant casualties and economic losses. Due to their occurrence in complex terrain areas, conventional geophysical techniques face challenges in early detection and warning of landslides ...

Orthogonal series approximation for boundary layers [PDF]

Theoretical and Applied Mechanics, 2004
In this paper we shall consider a class of singularly perturbed problems described by the ordinary differential equation of second order with small parameter multiplying the highest derivative and the appropriate boundary conditions, which describes ...

Thrust Prediction of Aircraft Engine Enabled by Fusing Domain Knowledge and Neural Network Model

Aerospace, 2023
Accurate prediction of aircraft engine thrust is crucial for engine health management (EHM), which seeks to improve the safety and reliability of aircraft propulsion. Thrust prediction is implemented using an on-board adaptive model for EHM. However, the

An Approximate Schur Decomposition-Based Spatial Domain Color Image Watermarking Method

IEEE Access, 2019
In this paper, an approximate Schur decomposition-based spatial domain blind color image watermarking method is proposed to protect the copyright of color images, which has low computation complexity similiar to the watermarking technique in the spatial ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A class of alternate strip-based domain decomposition methods for elliptic partial differential Equations [PDF]

, 2005
The domain decomposition strategies proposed in this thesis are efficient preconditioning techniques with good parallelism properties for the discrete systems which arise from the finite element approximation of symmetric elliptic boundary value problems
