Minimum isolated failure immune networks are shown to be 2–trees. Further, subgraphs of 2‐trees
are shown to be exactly those graphs which contain no subgraph homeomorphic to …

The query inference problem is to translate a sentence of a query language into an unambiguous
representation of a query. A query is represented as an expression over a set of query …

Various network reliability problems are #P-complete, however, certain classes of networks
such as series-parallel networks, admit polynomial time algorithms. We extend these efficient …

The problem of generating reasonable natural language-like responses to queries formulated
in nonnavigational query languages with logical data independence is addressed. An …

In this paper we present a method for variable resolution terrain modeling. This methodology
depends strongly on the concepts of self-similarity and minimum desired resolution. Among …

A characterization of an end user and a discussion of an end-user facility are presented. A
language for aiding the data-base administrator in designing forms for user's of an end-user …

In the computer simulation of combat over a specific geographical area, the terrain is typically
represented using sets of isolated, measured terrain altitudes. The inverse problem is to …

Digitized terrain data corresponding to a given geographical area are generally available in
a rectangular grid at some fixed resolution. In the modeling and simulation of processes that …

This paper describes a system for generating attributed translators. The translator is based
on an LL(1) parser generator which has been augmented with error detection and recovery …
