Large-scale motions from a direct numerical simulation of a turbulent boundary layer [PDF]
, 2018 A study of large-scale motions from a new direct numerical simulation database of the turbulent boundary layer up to Re{\theta} ~ 2500 is presented. The statistics of large-scale streamwise structures have been investigated using two-dimensional and ...

A fast semi-direct least squares algorithm for hierarchically block separable matrices [PDF]
, 2014 We present a fast algorithm for linear least squares problems governed by hierarchically block separable (HBS) matrices. Such matrices are generally dense but data-sparse and can describe many important operators including those derived from ...

Brain Tissue Evaluation Based on Skeleton Shape and Similarity Analysis between Hemispheres
Computation, 2020 Background: The purpose of this article is to provide a new evaluation tool based on skeleton maps to assess the tumoral and non-tumoral regions of the 2D MRI in PD-weighted (proton density) and T2w (T2-weighted type) brain images.
