Description for Multiple Media Generators
To generate multimedia explanations, a system must be able to coordinate the use of different media in a single explanation. In this paper, we present an architecture that we have developed for COMET (COordinated Multimedia Explanation Testbed), a system that generates directions for equipment maintenance and repair, and we show how it addresses the coordination problem. In particular, we focus...
متن کاملTrue Random Number Generators
Random numbers are needed in many areas: cryptography, Monte Carlo computation and simulation, industrial testing and labeling, hazard games, gambling, etc. Our assumption has been that random numbers cannot be computed; because digital computers operate deterministically, they cannot produce random numbers. Instead, random numbers are best obtained using physical (true) random number generator...
متن کاملMultiple attenuation in the image space
Multiples can be suppressed in the angle-domain image space after migration. For a given velocity model, primaries and multiples have different angle-domain moveout and, therefore, can be separated using techniques similar to the ones employed in the data space prior to migration. We use Radon transforms in the image space to discriminate between primaries and multiples and employ accurate func...
متن کاملInverse scattering internal multiple attenuation algorithm: an analysis of the pseudo-depth and time monotonicity requirements
Pseudo-depth monotonicity condition is an important assumption of the inverse scattering internal multiple attenuation algorithm. Analysis reveals that this condition is equivalent to a vertical-time monotonicity condition which is different than the total traveltime monotonicity suggested in recent literature/discussions. For certain complex media, the monotonicity condition can be too restric...
متن کاملMultiple attenuation in VSP multiple imaging and primary imaging
Imaging of downgoing first-order free-surface multiples (ghosts) with VSP data can provide a subsurface image with wider coverage, better vertical resolution, and higher-fold than conventional imaging of VSP primary reflections. A problem with VSP downgoing first-order multiple (ghost) imaging is the interference from downgoing high-order multiples, similar to the interference from multiples wh...
