Faster 3D finite element time domain : Floquet absorbing boundary condition modelling using recursive convolution and vector fitting [PDF]
, 2009 A recursive convolution (RC) based on the vector fitting (VF) method and triangular temporal basis functions is employed to compute the Floquet absorbing boundary condition (FABC) formulation in the vector 3D finite element time-domain (FETD) modelling ...

Wave input method for saturated soil-structure dynamic interaction analysis
Yantu gongcheng xuebao, 2018 In the process of establishing the numerical model to study the soil-structure dynamic interaction problem, the wave input method and the simulation of wave propagation behavior within the semi-infinite medium are critical.

Space–time proper generalized decompositions for the resolution of transient elastodynamic models [PDF]
, 2013 In this paper, we investigate ability of proper generalized decomposition (PGD) to solve transient elastodynamic models in space–time domain. Classical methods use time integration schemes and an incremental resolution process.

Domain Reduction for Valued Constraints by Generalising Methods from CSP [PDF]
, 2018 For classical CSPs, the absence of broken triangles on a pair of values allows the merging of these values without changing the satisfiability of the instance, giving experimentally verified reduction in search time. We generalise the notion of broken triangles to VCSPs to obtain a tractable value-merging rule which preserves the cost of a solution.

A reduced domain pool based on DCT for a fast fractal image encoding
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2011 Fractal image compression is time consuming due to the search of the matching between range and domain blocks. In order to improve this compression method, we propose firstly, in this paper, a fast method for reducing the computational complexity of ...

Fast Full-Search Algorithm of Fractal Image Compression for Acceleration Image Processing
Science Journal of University of Zakho, 2023 A new processing algorithm based on fractal image compression is proposed for image processing efficiency. An image will partition into non-overlapping blocks called range blocks and overlapping blocks called domain blocks, with the domain blocks ...
