Numerical Comparative Study of Compressible and Incompressible Models for Predicting Combined Natural Convection and Radiation in Participating Medium [PDF]

open access: yesJournal of Applied Fluid Mechanics
Natural convection coupled with volumetric radiation governs heat transfer in high-temperature systems, yet modeling relies heavily on the Boussinesq approximation, limited to weak density variations.

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.

Time to Compress the Time to First Compression [PDF]

open access: yesJournal of the American Heart Association, 2018
Out‐of‐hospital cardiac arrest (OHCA), often described as the most time‐sensitive and life‐threatening medical condition, remains a major public health problem.[1][1] Survival remains low in most settings, with enormous variation in community outcomes.[2][2] Although several ...

A Dilating Vortex Particle Method for Compressible Flow with Applications to Aeroacoustics [PDF]

open access: yes, 2002
Vortex methods have become useful tools for the computation of incompressible fluid flow. In the present work, a vortex particle method for the simulation of unsteady two-dimensional compressible flow is developed and applied to several problems.

DNABIT Compress-Genome Compression Algorithm [PDF]

open access: yesBioinformation, 2011
Data compression is concerned with how information is organized in data. Efficient storage means removal of redundancy from the data being stored in the DNA molecule. Data compression algorithms remove redundancy and are used to understand biologically important molecules. We present a compression algorithm, "DNABIT Compress" for DNA sequences based on
