In 1988 M. Fellows conjectured that if a finite, connected graph admits a finite planar emulator, then it admits a finite planar cover. We construct a finite planar emulator for K4,5 − 4K2. D. Archdeacon [2] showed that K4,5 − 4K2 does not admit a finite planar cover; thus K4,5 − 4K2 provides a counterexample to Fellows’ Conjecture. It is known that S. Negami’s Planar Cover Conjecture is true i...
متن کاملGerard Medioni and Ramakant Nevatia
Images are 2-dimensional projections of 3-dimensional scenes, therefore depth recovery is a crucial problem in image understanding, with applications in passive navigation, cartography, surveillance, and industrial robotics. Stereo analysis provides a more direct quantitative depth evaluation than techniques such as shape from shading, and its being passive makes it more applicable than active ...

متن کاملPopulation Growth in Planaria Dugesia tigrina (Gerard)
Planaria reproduce by transverse fission. Isolated worms increase in number exponentially, while social animals at the same density are inhibited in terms of numerical increase, but over a 25 day period undergo a larger increase in mass. Isolated posterior fission products reproduce faster than isolated anterior fission products. Regulation of population growth is independent of density over a ...
متن کاملGerard Debreu on the Integration of Correspondences ∗
In 1967, Gerard Debreu presented an integral of a correspondence by taking a higherdimensional point of view whereby a correspondence is seen as a function in a Banach space and thereby integrated as a consequence of the theory of Bochner integration. In this survey paper, we locate Debreu’s paper from the viewpoint of subsequent work, both in the theory of embeddings of convex-valued correspon...
