The dose from heavy ion beams has been calculated using a one-dimensional transport theory and evaluated for 670 MeV/ amu 20Ne beams in water. The result is presented so as to be applicable to… (More)
In ray tracing a surface of revolution, the problem of finding the point of intersection of an arbitrary ray with the surface of revolution can be reduced to that of finding a point of intersection… (More)
We present a method for modeling and rendering various surface textures by actually defining them over the entire three-dimensional space. Once this is done any surface representable by an implicit… (More)
Visualization of scalar and vector fields in the immersive environment (CAVE - Cave Automated Virtual Environment) is very important for its application to radiation shielding research at NASA… (More)
A method for the almost exact matching of the histograms between two digitized images. with noise level comparable to the separation between two consecutive discrete gray levels, is presented. The… (More)
A new technique for dimensionality reduction for a most general pattern recognition problem is presented. The method consists of identi fyinig and eliminating the least desirable feature out of the… (More)
Generalized cylinders with straight line trajectories are discussed for modeling objects of various kinds. For these kinds of generalized cylinders the sweeping cross-section is allowed to change… (More)
