in natural gas treatment, the removal of co2 and h2s in acid gases is a critical concern. there are various purification technologies that can be used for the removal of acid gas impurities. absorption of acid gas into amines is one preferred method in gas industries. in the past, single amines was used, but recently in order to improve absorption performance, mixed amines with different solubi...

We used Mayer sampling technique—a method based on free energy perturbation, to calculate virial coefficients B2–B6 for hard-core Yukawa fluids with interaction range parameter, =1.8, 3.0, 4.0, 5.0, 8.0, 9.0, and 10. We used these coefficients in the virial equation of state (VEOS) to obtain compressibility vailable online 28 June 2009

We study the critical phenomena of the hard-sphere lattice gas on the simple cubic lattice with nearest neighbour exclusion by the Monte Carlo method. We get the critical exponents, β/ν = 0.313(9) and γ/ν = 2.37(2), where β is the critical exponent for the staggered density, γ for the staggered compressibility, and ν for the correlation length.

the dependence of some thermodynamic properties of spin-polarized liquid 3he such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. the lennard-jones potential has been used in our calculations. it has been found that for higher values of entropy, the spin polarization has greater ef...

the dried fruit of terminalia chebula is widely used for its laxative properties. the objective of the present study was to examine the flowability and compressibility of terminalia chebula fruit powder, subsequently developing its tablet formulations by utilizing wet granulation and direct compression technology. initial studies on flowability and compressibility revealed that the fruit powder...

• Sparse coding. • Structured sparsity (e.g., disjunct groups, trees): increased performance in several applications. • Our goal: develop a dictionary learning method, which – enables general overlapping group structures, – is online: fast, memory efficient, adaptive, – applies non-convex sparsity inducing regularization: ∗ fewer measurements, ∗ weaker conditions on the dictionary, ∗ robust (w....
