1 |  | Hansen, Charles D. | Accelerated isosurface extraction in time-varying fields | For large time-varying data sets, memory and disk limitations can lower the performance of visualization applications. Algorithms and data structures must be explicitly designed to handle these data sets in order to achieve more interactive rates.

3 |  | Stringfellow, Gerald B.; Shurtleff, James Kevin | Adsorption and desorption of the surfactant Sb on GaInP grown by organometallic vapor phase epitaxy | It has been determined that ordering has a profound effect on the bandgap energy of many compound semiconductor alloys. Therefore, ordering must be controlled for devices such as solar cells, light emitting diodes and diode lasers. Since ordering depends on the surface properties during organomet... | Time dependent surface photoabsorption (SPA); Compound semiconductor alloys | 2000 |

5 |  | Gooch, Bruce; Reinhard, Erik; Moulding, Chris; Shirley, Peter S. | Artistic composition for image creation | Altering the viewing parameters of a 3D object results in computer graphics images of varying quality.

6 |  | Shirley, Peter S.; Gooch, Bruce | Artistic vision: painterly rendering using computer vision techniques | We present a method that takes a raster image as input and produces a painting-like image composed of strokes rather than pixels. Unlike previous automatic painting methods, we attempt to keep the number of brush-stroke small. This is accomplished by first segmenting the image into features, finding... | Painting-like image; Raster image; Painterly rendering | 2000 |
7 |  | Myers, Chris J. | Automatic abstraction for synthesis and verification of deterministic timed systems | This paper presents a new approach for synthesis and verification of asynchronous circuits by using abstraction.
