On the Compressibility of Tensors [PDF]
SIAM Journal on Matrix Analysis and Applications, 2021 Tensors are often compressed by expressing them in low rank tensor formats. In this paper, we develop three methodologies that bound the compressibility of a tensor: (1) Algebraic structure, (2) Smoothness, and (3) Displacement structure. For each methodology, we derive bounds on storage costs that partially explain the abundance of compressible ...

Analytical and numerical analysis of nonisothermal compressible rarefied gas flow between parallel plates [PDF]
Theoretical and Applied Mechanics, 2023 When dimensions of the flow domain become small, such as in the micro-electro-mechanical systems (MEMS) and nano-electro-mechanical systems (NEMS), rarefaction effects become more prominent.

Graphene meta-aerogels: When sculpture aesthetic meets 1D/2D composite materials
Nano Research Energy, 2022 The engraving technique has grown in parallel with our human civilization, along with the targeted materials evolving from stone and metals to wood. Benefiting from the blossom of nanotechnology, the bulky nicking tools have downsized themselves to a ...

Sonic Eddy Model of the Turbulent Boundary Layer
Fluids, 2022 The effects of Mach number on the skin friction and velocity fluctuations of the turbulent boundary layer are considered through a sonic eddy model. Originally proposed for free shear flows, the model assumes that the eddies responsible for momentum ...

A Compressible Turbulence Model for Pressure—Strain
Fluids, 2022 This work focuses on the performance and validation of compressible turbulence models for the pressure-strain correlation. Considering the Launder Reece and Rodi (LRR) incompressible model for the pressure-strain correlation, Adumitroaie et al., Huang et

Compressible two-dimensional turbulence: cascade reversal and sensitivity to imposed magnetic field
New Journal of Physics, 2023 We study the impact of compressibility on two-dimensional turbulent flows, such as those modeling astrophysical disks. We demonstrate that the direction of cascade undergoes continuous transition as the Mach number Ma increases, from inverse at Ma = 0 ...

Compression-Based Compressed Sensing [PDF]
IEEE Transactions on Information Theory, 2017 Modern compression algorithms exploit complex structures that are present in signals to describe them very efficiently. On the other hand, the field of compressed sensing is built upon the observation that "structured" signals can be recovered from their under-determined set of linear projections.

Uniform regularity for the isentropic compressible magneto-micropolar system
Mathematical Modelling and Analysis, 2021 In this paper, we are concerned with the uniform regularity estimates of smooth solutions to the isentropic compressible magneto-micropolar system in . Under the assumption that , and by applying the classic bilinear commutator and product estimates, the

From compression to compressed sensing [PDF]
2013 IEEE International Symposium on Information Theory, 2013 Can compression algorithms be employed for recovering signals from their underdetermined set of linear measurements? Addressing this question is the first step towards applying compression algorithms for compressed sensing (CS). In this paper, we consider a family of compression algorithms $\mathcal{C}_r$, parametrized by rate $r$, for a compact class ...
