The compressibility of graphene [PDF]
Solid State Communications, 2012 We present a review of the electronic compressibility of monolayer and bilayer graphene. We focus on describing theoretical calculations of the effects of electron--electron interactions and various types of disorder, and also give a summary of current ...

The Structure and Compression of Medical Compression Stockings [PDF]
Materials, 2022 This paper lays out standards of compression stockings and their classification into classes. The analysis of knitted fabric structure parameters, elongation and compression of moderate- and high-compression stockings was conducted. Stocking compression on specific parts of the stocking leg was measured on three sizes of a wooden leg model.

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 ...

Clustering by Compression [PDF]
IEEE Transactions on Information Theory, 2003 We present a new method for clustering based on compression. The method doesn't use subject-specific features or background knowledge, and works as follows: First, we determine a universal similarity distance, the normalized compression distance or NCD, computed from the lengths of compressed data files (singly and in pairwise concatenation).

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.

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 ...

Astronomy & Astrophysics, 2014 We introduce the concept of compressed convolution, a technique to convolve a given data set with a large number of non-orthogonal kernels. In typical applications our technique drastically reduces the effective number of computations. The new method is applicable to convolutions with symmetric and asymmetric kernels and can be easily controlled for an

Designing compression of preventive compression stockings [PDF]
Journal of Engineered Fibers and Fabrics, 2021 The paper focuses on leg diseases and the application of preventive compression stockings in people who perform their working tasks in the standing position, pregnant women and recreational athletes. Specific amounts of compression classes from several significant European standards are shown.

Investigation into the compressibility of different types of sand fractions using a oedometer
Engineering Structures and Technologies, 2011 This work presents experimental tests on typical Baltic sea-shore sand along Klaipėda. The paper looks into changes in loaded soil void ratio when using different types of sand fractions in Klaipėda region.
