Two optimization approaches to correct the physical limitations of the Lee–Kesler–Plöcker equation of state for the application to long-ch
However, there is still some error in predicting the critical point and behavior of natural gas mixtures near the phase envelope; the (P-R) EOS typically provides more accurate results for this calculation. In addition, various software that use the same equation of state, implement the mixing...

(7.44), then obtain the state-transition matrix for the system x˙(t)=[01−2−3]x(t) Solution The state matrix is in companion form, and its characteristic equation can be directly written with the coefficient obtained by negating the last row of the matrix λ2+3λ+2=(λ+1)(λ...
In last year’s report, we did not publish our annual list of “super winners,” due to distortions and reporting gaps caused by the pandemic. This year, we return to our analysis but with an adapted approach: smoothing pandemic-induced distortions by calculating the average economic profit ov...
We describe recent three-flavor QCD lattice data for the pressure, speed of sound and interaction measure at nonzero temperature and vanishing chemical potential within a virial expansion. For the deconfined phase, we use an effective potential inspired by a phenomenological model which includes non...

The corresponding-states principle of the equation of state is here introduced as, (2.12)pVRT=F(VVc,TTc)=F(Vr,Tr) The modern theories of the equation of state investigate the virial coefficients of the series expansion in the universal form of the corresponding-states principle, (2.13)pVRT=...
