rainfall erosivity is the ability of rainfall to detach the soil particles. this study was conducted to evaluate spatial variability of rainfall erosivity indices in khouzestan province. the point data of indices (ei30, aim, ke>1 and onchev indices) in 74 stations were used to generate spatial erosivity maps through deterministic and geostatistical interpolation methods (radial basis functions,...

Distance to the kth nearest facility is important when facilities are closed Emergency facilities !! Hospitals !! Fire stations !! Refuges Facilities are closed because of accidents and disasters Analytical expressions for the kth nearest distance have been obtained Grid Random Grid Random For finding the relationship between the distances, we need the joint distribution Distribution of the kth...

I have designed, built, and evaluated a passive radiolocation system that uses only signals of opportunity, that is, signals that exist for purposes other than radiolocation. The system estimates the relative position vector between a base station, which is a navigation receiver at a known location, and a rover, which is like the base station but free to move about. The relative position vector...

This paper derives the distribution of the deviation distance to visit an alternative fuel station. Distance is measured as the Euclidean distance on a continuous plane. The distribution explicitly considers the vehicle range and whether the round trip between origin and destination can be made. Three cases are examined: fuel is available at both origin and destination, fuel is available at eit...

Recent work has achieved promising retrieval performance using distance between term occurrences as a primary estimator of document relevance. A major bene t of this approach is that relevance scoring does not rely on collection frequency statistics. A theoretical framework for lexical spans is now proposed which encompasses these approaches and suggests a number of important directions for fut...

Greater sage-grouse populations have decreased steadily since European settlement in western North America. Reduced availability of brood-rearing habitat has been identified as a limiting factor for many populations. We used radio-telemetry to acquire locations of sage-grouse broods from 1998 to 2012 in Strawberry Valley, Utah. Using these locations and remotely-sensed NAIP (National Agricultur...

Computing the Fréchet distance for surfaces is a surprisingly hard problem. It has been shown that it is NP-hard to compute the Fréchet distance between many nice classes of surfaces [God98], [Buc10]. On the other hand, a polynomial time algorithm exists for computing the Fréchet distance between simple polygons [Buc06]. This was the first paper to give an algorithm for computing the Fréchet di...
