We introduce a new representation for modeling and rendering plants trees. The is multiresolution can be automatically generated rendered in an efficient way. For the trunk branches we procedurally build structure that preserves visual appearance of tree, when at different levels detail. leaves hierarchy images by pre-processing botanical tree structure. Unlike other representations, quality our does not depend on viewing position direction. Our models applied to any computer graphics area...
Nanocrystalline Sm0.5Y0.5Co5 alloys were prepared by mechanical milling, and their magnetic properties investigated using a physical property measurement system (PPMS) to observe the presence of interactions determine dipolar interaction field. Isothermal remanent magnetization curves (mr) normalized direct current demagnetization (md) measured. The field for nanocrystalline was determined, representative interactions.
Nanocrystalline Y0.5Sm0.5Co5 ribbons were obtained by melt spinning using a copper wheel surface speed of 40 m/s. X-ray diffraction patterns from the as-cast ground alloy and melt-spun indexed as CaCu5-like hexagonal structure. Crystallographic texture was observed dendritic microstructure with dendrite size between 1 5 μm noncontacting ribbon measured. In addition, finer on contacting observed. Magnetic measurements, corrected for demagnetizing field, show nonsaturated magnetization curve....
Nanocrystalline Sm0.5Y0.5Co5 powders (average crystal size d = 12 nm) were produced by arc melting pure metals followed mechanical milling and annealing. Different milling/annealing times annealing temperatures used to optimize the hard magnetic properties of these nanopowders. A noticeably enhanced coercivity remanence (coercivity 2.1 MA/m, σr/σmax 0.7 respectively) observed in samples milled for 240 minutes then annealed 1 minute at Temperatures ~1200K. Such remarkable stem from high...
