Journal ArticleDOI
Fast iterative method in solving eikonal equations : A multi-level parallel approach
Florian Dang,Nahid Emad +1 more
TL;DR: This paper investigates a multi-level parallel approach for the fast iterative method which is well fitted for today heterogenous and hierarchical architectures and gives a performance analysis.
Journal ArticleDOI
The Lanczos algorithm and Hankel matrix factorization
TL;DR: The connections between the Lanczos algorithm for matrix tridiagonalization and two fast algorithms for Hankel matrix factorization are explored and how the asymmetric Lanczos process is related to the Berlekamp-Massey algorithm is shown.
Journal ArticleDOI
On the Stability of Gravitating Nonabelian Monopoles
TL;DR: In this article, the behavior of magnetic monopole solutions of the Higgs equations subject to linear spherically symmetric perturbations is studied using Jacobi's criterion and some of the monopoles are shown to be unstable.
Journal ArticleDOI
GuideME: slice-guided semiautomatic multivariate exploration of volumes
Liang Zhou,Charles Hansen +1 more
TL;DR: The proposed GuideME is a novel slice‐guided semiautomatic multivariate volume exploration approach that comprises four stages: attribute inspection, guided uncertainty‐aware lasso creation, automated feature extraction and optional spatial fine tuning and visualization.
Journal ArticleDOI
Novel Pipelined Architecture for Efficient Evaluation of the Square Root Using a Modified Non-Restoring Algorithm
TL;DR: It is demonstrated that the proposed architecture is approximately four times faster than its popular counterparts and at the same time it consumes 50% less energy for envelope detection at 268 MHz sampling rate.
