L(h, 1, 1)-labeling of outerplanar graphs

Calamoneri, Tiziana; Fusco, Emanuele; Tan, Richard; … - In: Computational Statistics 69 (2009) 2, pp. 307-321

An L(h, 1, 1)-labeling of a graph is an assignment of labels from the set of integers {0, . . . , λ} to the nodes of the graph such that adjacent nodes are assigned integers of at least distance h ≥ 1 apart and all nodes of distance three or less must be assigned different labels. The aim...

Freedom of access to the radio spectrum for satellite communications

Withers, David - In: Telecommunications Policy 9 (1985) 2, pp. 109-120

A conference will open on 8 August 1985 under ITU auspices to consider major procedural changes in the international regulation of the use of the radio spectrum by geostationary satellites. There has been strong pressure for the introduction of a priori orbit/ spectrum planning for, for example,...
