The effect of both surface coupling Js and surface magnetic field Hs on the dependency of the layering temperature TL as a function of the thickness N , of a spin−1/2 Ising film is studied using mean field theory. It is found that for Js greater than a critical value (Jsc = 1.30), the layering temperature decreases when the film thickness N increases for any values of Hs. While, for Js < Jsc, t...

In this note we deene a layering intended to structure the many concepts which arise in the development of an Engineering Information System. The industrial beneets to be gained by such a layering are enumerated. An Engineering Information System (EIS) is a collection of facilities and services that provide support for the design, testing, manufacture, and maintenance of engineering artifacts, ...

We review various simplified models that have been advanced to describe layering (complexion) transitions at grain boundaries in multicomponent solids. In particular, we first outline lattice-gas, off-lattice atomistic and thermodynamic models that have been employed to investigate phase-like behavior at segregated grain boundaries. The results of these investigations are summarized in the form...

The classical definition of Steiner symmetrizations functions are defined according to the function level sets and layered representation functions. In this paper, is not only transformed into one-dimensional parabolic functions, but also depends on log-concave To end we prove Steiner’s inequality layering in space
