โœฆ Synopsis

Starting from the definition of cohesive energy density and the solubility parameter, the latter can be estimated using equations of state. We have used the linear isotherm regularity (LIR), Ihm-Song-Mason (ISM), and Peng-Robinson (PR) equations of state to predict the solubility parameter. The solubility parameter of various liquids has been computed at different temperatures and pressures and compared with the experimental values. We have generated the experimental values of solubility parameter using the relation between internal pressure and solubility parameter, the latter is the root of former. The equation of state character of the approach permits us the computation of solubility parameters over extended ranges of temperatures and pressures.

In modal parameter identification, the damped complex exponential response methods extract modal parameters using free decay responses. Although there are several different complex exponential methods, they are based on the Prony method. The Prony method has some limitations, such as poor robustness

This paper annlJ;es the application of Laguerre polynomial expansion to linear systems. It can be applied to the solution of linear state equations by using an algebraic matri.u to determine the coejicients of the Laglrerre expansion. It also can be applied to system identification by using the expa
