Temperature-dependent compressibility in graphene and two-dimensional systems

open access: yes, 2011
We calculate the finite temperature compressibility for two-dimensional semiconductor systems, monolayer graphene, and bilayer graphene within the Hartree-Fock approximation.

Compressional behavior of knitted fabrics exposed to repeated wash and wear cycles [PDF]

open access: yesHemijska Industrija, 2006
The quality requirements of knitted fabrics nowadays have become highly demanding in terms of appearance and comfort properties. It is well known that yarns are subjected to tension, bending, torsion and compression during the wear and care of apparels ...

Compressibility of a two-dimensional extended Hubbard model

open access: yes, 2005
The compressibility of an extended $d-p$ Hubbard model is investigated by the Roth's two-pole approximation. Using the factorization procedure proposed by Beenen and Edwards, superconductivity with singlet $d_{x^2-y^2}$-wave pairing is also considered ...

In situ measurements of density fluctuations and compressibility in silica glass as a function of temperature and thermal history

open access: yes, 2005
In this paper, small-angle X-ray scattering measurements are used to determine the different compressibility contributions, as well as the isothermal compressibility, in thermal equilibrium in silica glasses having different thermal histories.

Compression with actions

open access: yes2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
We consider the setting where actions can be used to modify a state sequence before compression. The minimum rate needed to losslessly describe the optimal modified sequence is characterized when the state sequence is either non-causally or causally available at the action encoder.

Soil Structure under Forest and Pasture Land-Uses Affecting Compressive Behavior and Air Permeability in a Subtropical Soil

open access: yesSoil Systems, 2022
Machinery traffic and animal trampling can deform the soil and, consequently, impair soil pore functioning. This study aimed to evaluate how soil structure affects the compressibility, physical properties and air permeability of a Typic Paleudalf under ...

Compressibility in turbulent MHD and passive scalar transport: mean-field theory

open access: yes, 2018
We develop a mean-field theory of compressibility effects in turbulent magnetohydrodynamics and passive scalar transport using the quasi-linear approximation and the spectral $\tau$-approach. We find that compressibility decreases the $\alpha$ effect and

Compressibility of rotating black holes [PDF]

open access: yes, 2011
Interpreting the cosmological constant as a pressure, whose thermodynamically conjugate variable is a volume, modifies the first law of black hole thermodynamics.

A Comparison of Data Reduction Methods for Average Friction Factor Calculation of Adiabatic Gas Flows in Microchannels

open access: yesMicromachines, 2019
In this paper, a combined numerical and experimental approach for the estimation of the average friction factor along adiabatic microchannels with compressible gas flows is presented. Pressure-drop experiments are performed for a rectangular microchannel
