Topological Sorting is a standard computation performed on finite partial order relations, for which efficient algorithms are well known.
This work is a study of using a depth-first search of a directed graph to implement topological sorting algorithms. A new algorithm is presented, along with a discussion of how it...
Information derived from a Landsat Multispectral Scanner CMSS) scene can be used to assign individual pixels, each representing about one acre on the Earth's surface, to natural resource classes, A lineprinter can be used to generate a 1:24,000 scale map of the scene in which each symbol corresponds to a...
Over the past few years Qualitative Reasoning about physical systems has emerged strongly as an important area in Artificial Intelligence. Many qualitative reasoning formalisms have been developed and applied to varied domains, namely, hydraulic systems, electrical systems, industrial control etc.
This paper examines Qualitative Process Theory [Forbus 84] formalism in...
This paper describes a mathematical formulation and a computer program
in basic language for analyzing the load carrying capacity of skyline
systems using the effects of log drag. The actual log and ground geometry
are used in the analysis of the payload capacities for standing, live and
running skylines. The...
The language G is an expression based language designed around the concept of the stream; where a stream is a sequence of values, perhaps infinite in length. There are no statements in G, only expressions. All expressions are evaluated on a demand driven basis, no computation takes place that does...
This paper presents equations developed to predict the height to live crown base of six species in the central western Willamette Valley of Oregon. Weighted nonlinear regression was used to fit a separate logistic equation for each species. The predictor variables are total tree height, crown competition factor in trees...
Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...
