However, although these models cover important characteristics of SSMDs, the influences of the guiding system on the performance of SSMDs are not systematically investigated yet.This paper gives an overview of the up-to-date research activities of SSMDs regarding to the modeling of SSMDs and summarizes important key aspects of the issue.
Typically, the contact elements are made of wear resistant material such as hardened steel or sapphire with the shape of sphere or half-sphere.
In precision mechanical engineering preloaded-guides (or free backlash guides) are used including ball bearings, air bearings, active magnet bearings as well as flexure structure.

Some of the practical applications are flow through packed beds, underground disposable of radioactive waste materials, metal spinning, exothermic and endothermic reactions, etc.
The Magneto-hydro-dynamics (MHD) was applied in many areas of science, engineering and technology, such as MHD power generators, MHD flow meters, MHD pumps, polymer industry, spinning of filaments, etc.
These effects are significantly used in geosciences and chemical engineering.
These parameters have a key role to adjust and control the convergence of the solutions.

Introduction Various kinds of silicon carbide (SiC) electronic devices have been developed using a key technology, step-controlled epitaxy, for high-quality epilayers on off-axis (0001) substrates by CVD [1].
Different bond configurations on non-standard surfaces might lead to a different removal process of C-related materials from the interface during oxidation and to the reduced number of electrically active states near the band edge.
