Book ChapterDOI
Approximating anatomical brain connectivity with diffusion tensor MRI using kernel-based diffusion simulations
TL;DR: In this article, a technique for noninvasively tracing brain white matter fiber tracts using diffusion tensor magnetic resonance imaging (DT-MRI) is presented. But it is based on performing diffusion simulations over a series of overlapping three dimensional diffusion kernels that cover only a small portion of the human brain volume and are geometrically centered upon selected starting voxels where a seed is placed.
Journal ArticleDOI
Three-dimensional model on thermal response of skin subject to laser heating.
TL;DR: A three-dimensional (3D) multilayer model based on the skin physical structure is developed to investigate the transient thermal response of human skin subject to laser heating and the expected simulation results are obtained.
Proceedings ArticleDOI
Addressing Accuracy Issues in Privacy Preserving Data Mining through Matrix Factorization
TL;DR: Experimental results demonstrate that mining accuracy on the distorted data used by matrix factorization-based data distortion schemes is almost as good as that on the original data, with added property of privacy preservation.
Journal ArticleDOI
A short survey on preconditioning techniques for large-scale dense complex linear systems in electromagnetics
Yin Wang,Jeonghwa Lee,Jun Zhang +2 more
TL;DR: A short survey of a few preconditioned Krylov subspace methods used in electromagnetics simulations in the context of multilevel fast multipole algorithms (MLFMA) and some numerical results are presented.
Journal ArticleDOI
A grid-based multilevel incomplete LU factorization preconditioning technique for general sparse matrices
TL;DR: A grid-based multilevel incomplete LU preconditioner for solving general sparse matrices that avoids some controversial issues in algebraic multigrid method such as how to construct the interlevel transfer operators and how to compute the coarse level operator.
