Schema-based representations for visual knowledge are integrated with constraint satisfaction techniques. This integration is discussed in a progression of three sketch map interpretation programs: Mapsee-1, Mapsee-2, and Mapsee-3. The programs are evaluated by the criteria of descriptive and procedural adequacy. The evaluation indicates that a schema-based representation used in combination wi...

(1.1) M' is complete and its sectional curvatures are non-positive. In terms of local coordinates x = (x, . . . , x) on M and y = (y, . . . , y) on M', let the respective Riemann elements of arc-length be ds = gij dx dx\ ds' = g'a$ dy a dy& and r^-fc, T'Vy be the corresponding Christoffel symbols. When there is no danger of confusion, x (or y) will represent a point of M (or M') or its coordina...

This study addresses the design issues of an intelligent system for image understanding applied to remote sensing minefield area reduction. We propose a system using a combination of image processing techniques and a knowledge-based intelligent scheme that interactively cooperate together to produce a danger map of the surveyed area. This contribution suggests a semantic knowledge-based scene i...

Upper Indus Basin (UIB) is critical for Pakistan’s economy as it glacial incomposition and snow melt that provides 80% of the fresh water to River. Decadal fluctuationsin precipitation in UIB during 1980-2010, using interpolation technique Arc Map were exploredin present study. The results provided a positive correlation between winter andsummer runoff middle elevation basins UIB. map decadal d...

In the first two volumes of Fundamenta Mathematica, Knaster and Kuratowski raised the following two questions [15], [16]: (1) If a nondegenerate, bounded plane continuum is homogeneous, is it necessarily a simple closed curve? (2) Does there exist a continuum each subcontinuum of which is indecomposable? Although Knaster settled the second question in 1922 [14], it was to remain until 1948 for ...

We report sub-arcsecond X-ray imaging spectroscopy of M87 and the core of the Virgo cluster with the Chandra X-ray Observatory. The X-ray morphology shows structure on arcsecond (∼ 100 pc) to ten arcminute (∼ 50 kpc) scales, the most prominent feature being an “arc” running from the east, across the central region of M87 and off to the southwest. A ridge in the radio map, ending in an “ear”-sha...

Homeomorphisms between curves and between surfaces are fundamental to many applications of 3D modeling, graphics, and animation. They define how to map a texture from one object to another, how to morph between two shapes, and how to measure the discrepancy between shapes or the variability in a class of shapes. Previously proposed maps between two surfaces, S and S ′, suffer from two drawbacks...
