Large-scale alignment of lamellae in thin films of diblock copolymers containing polyacrylonitrile and poly(n-butyl acrylate) was achieved by casting copolymer solution on a silicon substrate moved away at a constant speed from the casting nozzle (zone-casting). Grazing incidence small-angle X-ray scattering revealed that the lamellae, which were perpendicular to the substrate, were also aligne...

Riser sleeves are an effective tool in the steel foundry industry for minimizing riser size and increasing casting yield. Reliable simulation of the performance of riser sleeves requires accurate temperature dependent thermophysical properties. Unfortunately there is little or no such property data available in the open literature. A limited number of sleeve manufacturers provide advice and pro...

We propose a simple modi cation to the classical polygon rasterization pipeline that enables exact, e cient raycasting of bounded implicit surfaces without the use of a global spatial data structure or bounding hierarchy. Our algorithm requires two descriptions for each object: a (possibly non-convex) polyhedral bounding volume, and an implicit equation (including, optionally, a number of clipp...

The rate of solidification affects the microstructure, quality and mechanical properties of the castings. The analysis of heat transfer in centrifugal casting is very complex due to rapid solidification, rotating mould, opaque mould and high temperature. As the grain size is directly depending on the rate of solidification of the casting, based on grain size the rate of solidification of the ce...
