Terrain effects on bus maintenance performance
(National Academy Press, 1987)
In this paper, a methodology to classify terrain is presented. The taxonomy is devised using a terrain template based on evidence from topographic maps, and the resulting classes are characterized as steep, intermediate, ...

A linear algorithm for the cutting center of a tree
(Elsevier, 1986-11-24)
As a measure of the extent to which the removal of a node disconnects a graph, the cutting number c(v) of a node v in a connected graph G has been defined to be the number of pairs of nodes in different components of G-{v}. ...
Urban Rank-Size Hierarchy: A Mathematical Interpretation
(Institute of Mathematical Geography, 1988)
Boolean distance for graphs
(Elsevier, 1982)
The boolean distance between two points x and y of a connected graph G is defined as the set of all points on all paths joining x and y in G (O if X = y). It is determined in terms of the block-cutpoint graph of G, and ...
Digital metrics: A graph-theoretical approach
(Elsevier, 1984-03)
Consider the following two graphs M and N, both with vertex set Z x Z, where Z is the set of all integers. In M, two vertices are adjacent when their euclidean distance is 1, while in N, adjacency is obtained when the ...
Embedding and characterization of quantum chemical reaction graphs on two-dimensional orientable surfaces
(Elsevier, 1988-03)
Quantum chemical reaction graphs defined on multidimensional potential energy hypersurfaces are embedded on two-dimensional orientable surfaces. Topological invariants of these graphs and those of the embedding two-dimensional ...
Essays on Mathematical Geography--II
(Institute of Mathematical Geography, 1987)
As with Monograph #3 in this series, this volume also attempts to use pure mathematics in real-world settings. Table of Contents: The Atlantic Drainage Tree | Getting A Handel on Water-graphs | Terror In Transit: A Graph ...
