Correlation of Affinity Coefficient for Gas Adsorption by Structure-Activity Parameter.

Optimization of Extended UNIQUAC Model Parameter for Mean Activity Coefficient of Aqueous Chloride Solutions using Genetic+PSO

In the present study, in order to predict the activity coefficient of inorganic ions, 12 cases of aqueous chloride solution were considered (AClx=1,2; A=Li, Na, K, Rb, Mg, Ca, Ba, Mn, Fe, Co, Ni). For this study, the UNIQUAC thermodynamic model is desired and its adjustable parameters are optimized with the Genetic + PSO algorithm. The optimization of the UNIQUAC model with PSO+ genetic algorit...

A Correlation for the Prediction of the Adiabatic Joule-Thomson Coefficient of Pure Gases and Gas Mixtures

A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...

Correlation Coefficient Scanning to Identify Localised Activity

In this paper we suggest a method of approaching one biomagnetic modelling problem where subjective judgements are common; the identification of the number and locations of discrete regions of activity. These regions are often modelled as current dipoles. In multi-dipolar systems several different modelling approaches may be adopted. If there is a-priori evidence for a particular set of fixed l...
