Quantifying Compressibility and Slip in Multiparticle Collision (MPC) Flow Through a Local Constriction

open access: yesEntropy, 2014
The flow of a compressible fluid with slip through a cylinder with an asymmetric local constriction has been considered both numerically, as well as analytically.

An approximate formula for the H/V ratio of Rayleigh waves in compressible pre-stressed elastic half-spaces coated with a thin layer

open access: yesVietnam Journal of Mechanics, 2018
This paper is concerned with the propagation of Rayleigh waves in a compressible pre-stressed elastic half-space coated with a thin compressible pre-stressed elastic layer. The main purpose of the paper is to establish an approximate formula for the H/V

Compression2: compressed sensing with compressed coil arrays [PDF]

open access: yesJournal of Cardiovascular Magnetic Resonance, 2012
Summary Compressed sensing with PCA based coil compression is a promising way to obtain high quality radial perfusion images without incurring the high computation cost and memory requirements associated with large multi-coil arrays Background Imaging with large coil arrays is desirable for rapid imaging and high signal to noise ratio.

Remote Multilinear Compressive Learning With Adaptive Compression [PDF]

open access: yesIEEE Internet of Things Journal, 2022
Multilinear Compressive Learning (MCL) is an efficient signal acquisition and learning paradigm for multidimensional signals. The level of signal compression affects the detection or classification performance of a MCL model, with higher compression rates often associated with lower inference accuracy.

On large bending deformations of transversely isotropic rectangular elastic blocks [PDF]

open access: yes, 2007
In this paper we examine the classical problem of finite bending of a rectangular block of elastic material into a sector of a circular cylindrical tube in respect of compressible transversely isotropic elastic materials.
