Constructing an Index of Difficulty for Air Traffic Control Using Proximity Parameters

Procedia Engineering, 2015
In this paper, we propose an approach to constructing an index of air traffic control difficulty based on exponential functions of proximity parameters of aircraft pairs, i.e. the time to closest point of approach and miss distance. The index is given by

Proximity Expansion Index: An improved approach to characterize evolution process of urban expansion

Computers, Environment and Urban Systems, 2018
The spatial relationship of newly grown urban patches to existing urban areas lies at the core of understanding the properties of urban expansion dynamics. Some existing landscape metrics have been used to identify patch expansion types, i.e., infilling,

Indexed fast network proximity querying

Proceedings of the VLDB Endowment, 2018
Node proximity queries are among the most common operations on network databases. A common measure of node proximity is random walk based proximity, which has been shown to be less susceptible to noise and missing data. Real-time processing of random-walk based proximity queries poses significant computational challenges for larger graphs with over ...

Index for evaluation of public parks and gardens proximity based on the mobility network: A case study of Braga, Braganza and Viana do Castelo (Portugal) and Lugo and Pontevedra (Spain)

Urban Forestry and Urban Greening, 2018
Urban green space (UGS) indices are increasingly used and are mentioned by many authors. However, while indices relating to the amount of green space are widespread, other important information about UGSs (including proximity) is somehow disregarded ...

Indexing OODB instances based on access proximity

Proceedings 13th International Conference on Data Engineering, 2002
Queries in object-oriented databases (OODBs) may be asked with respect to different class scopes: a query may either request for object-instances which belong exclusively to a given class c, or those which belong to any class in the hierarchy rooted at c.

Distance based indexing for string proximity search

Proceedings 19th International Conference on Data Engineering (Cat. No.03CH37405), 2004
In many database applications involving string data, it is common to have near neighbor queries (asking for strings that are similar to a query string) or nearest neighbor queries (asking for strings that are most similar to a query string). The similarity between strings is defined in terms of a distance function determined by the application domain ...
