The article introduced the method of the roller pass virtual design by computer simulation technology. It discussed that based on the virtual roller classification, the constructed roll pass design virtual manufacture system components model, the vertical roll three dimensional virtual charts and the engineering plat. It discussed distortion process in the straight seam welded pipe production and...
The research presented in this paper aims at developing and validating a predictive tool of individual exposure to solar Ultra-Violet (UV). UV exposure depends on ambient irradiation level and individual factors related to activity (position to the sun, clothing, duration of exposure, and other forms of sun protection). We predict exposure levels of body parts on basis of ambient irradiation levels...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
