Correlation between global thermodynamic functions and experimental data in multicomponent heterogeneous systems

Some phenomenological and thermodynamic aspects of diffusion in multicomponent systems

During the last twenty years diffusion coefficients have been primarily measured by light scattering and NMR techniques. Optical interferometric techniques, such as those of Gouy or Rayleigh (ref. 1). allowing direct observation of the time evolution of a diffusing boundary are not very popular at present. However, they are the only ones that give a reasonably accurate measurement of the set of...

Quantum Global Strings and Their Correlation Functions

A full quantum description of global vortex strings is presented in the framework of a pure Higgs system with a broken global U(1) symmetry in 3+1D. An explicit expression for the string creation operator is obtained, both in terms of the Higgs field and in the dual formulation where a Kalb-Ramond antisymmetric tensor gauge field is employed as the basic field. The quantum string correlation fu...

the relationship between field-related cognitive styles and global reading comprehension of hypertext

this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...

Correlation functions in disordered systems.

Recently, we found that the correlation between the eigenvalues of random hermitean matrices exhibits universal behavior. Here we study this universal behavior and develop a diagrammatic approach which enables us to extend our previous work to the case in which the random matrix evolves in time or varies as some external parameters vary. We compute the current-current correlation function, disc...
