This paper describes an investigation of a matrix algebraic method to determine isomorphism in pairs of undirected graphs. The method is described in some detail. The theoretical as well as the practical difficulties are given. It is shown that the method works for some cases. When the adjacency matrix of...
This study involves logic design and switching theory, in particular their practical application to the logic design and understanding of digital machines. Digital machines, of course, play an extremely important role in that large class of machines known as digital computers. But they also play an important role in many...
The material in this paper is divided into the following four chapters for convenience. Chapter 1 explains, how the idea of fault testing changed from testing the machine instructions to testing the hardware in logic circuits. Chapters 2, 3 and 4 present the different approaches considered, namely:
1. Path sensitizing...
Microprogramming has evolved since its introduction in 1951 by Maurice Wilkes. The most significant change that has taken place is the recent growth of interest in user microprogramming. However, user microprogramming is a difficult task because of various complex and intricate features of the host processors. A microprogrammer must be...
Contemporary database systems are used in a variety of business applications requiring rapid retrieval of online data. When records contain unique information indexed by a single key, the retrieval operation can be simplified. However, when added generality and flexibility is needed, inverted files and sophisticated data models result in a...
A tour of a graph (digraph, or sequential machine) is a sequence of nodes from the graph such that each node appears at least once and two nodes are adjacent in the sequence only if they are adjacent in the graph. Finding the shortest tour. of a graph is known...
A general model of interactive problem solving is described. The model views interactive problem solving to be the product of cooperating subsystems. The operative subsystem selectively attends to and manipulates problem relevant information in search of a solution. The descriptive subsystem is capable of interpreting this behavior and of discussing...
An operator calculus for transforming assignment statements, loops, and choice constructs into equation-of-state expressions is shown to be powerful enough to synthetically execute a given computer program and its test data. A demonstration of the program is equivalent to applying an operator formalism to the equation-of-state in order to reduce...
G. Spencer Brown's book Laws of Form has been enjoying a vogue among social and biological scientists. Proponents claim that the book introduces a new logic ideally suited to their fields of study, and that the new logic solves the problems of self-reference. These claims are false. We show that...
Recently several simply computed graph theoretic measures of computer program complexity, testing and unstructuredness have been proposed. Most of them are based on a static analysis of the program graph. One of the best known and most widely accepted is the cyclomatic number. Another is the number of knots, or...
This monograph presents a proof grammar for a formal language containing property symbols of every finite type. The proof grammar is thus applicable to any finite level higher-order logic.
The unique features of this system are: first, its mode of presentation as a recursive discourse grammar rigorously constructed from the...
Local stability seems to imply global stability for population models. To investigate this claim, we formally define a population model. This definition seems to include the one-dimensional discrete models now in use. We derive a necessary and sufficient condition for the global stability of our defined class of models. We...
A graph fold is the special case of a graph homomorphism where the two identified vertices are both adjacent to a common vertex. Like homomorphisms, folds are related to the chromatic number and we obtain an Interpolation Theorem for folds. If X(G) = n, then G is absolutely n-chromatic if...
Context-free grammars with graph control provide a general framework for the various types of context-free grammars with regulated rewriting. The vertices or edges of the directed graph are labeled with the productions of the grammar. The only strings in the language generated by the grammar are those whose derivations correspond...
In analyses of multivariate data, a classification of the data into related groups is frequently desired. This is generally referred to as the clustering problem. It has been studied in detail and many clustering algorithms exist. Most of these algorithms, however, require experimenting with the actual data before satisfactory results...
This paper describes a Lesson Generating System for CAI, which, by relieving the course author from the burden of programming, provides an efficient means for developing courseware to augment classroom instruction.
The paper describes research on the representation of knowledge. The goal is to develop a formalism which can be used for the testing of hypotheses on the nature of human understanding and as a foundation or artificial intelligence programs. The ideas expressed herein are implemented in a program which converses...
The information processing industry is one of the fastest growing, and most dynamic industries on the scientific as well as business scene, today. Progress in designing and applying computing systems has out raced progress in evaluating their performance. In order to circumvent this trend, there should be a simultaneous development...
A digital computer is characterized by the instruction set it executes. Each machine instruction is a bit pattern which is to be interpreted by the central processing unit CPU. The traditional way to interpret a machine instruction is to use random hardware. A contemporary approach is to install a program...

The northern Oregon coast suffers extensive loss of land as a result of landslides which constitute the primary mechanism of coastline recession. Both real property and structures along the coast have been destroyed and this destruction will continue. In certain instances, it may be feasible to protect property by engineered...

Buffer strips have been proposed as a method for controlling temperature changes in streams adjacent to clear-cuttings. Nine small mountain streams in Oregon's Coast Range and Cascade Mountains were studied to determine the influence of buffer strips on water temperature. Timber volume in the strip, strip width, and canopy density...
Dover and rex sole larvae attain an exceptionally large size and have a long pelagic life. Dover sole larvae (9-65 mm standard length) were collected in mid-water trawls and plankton nets during all months of the year. Judging from growth of larvae and occurrence in bottom trawls of recently metamorphosed...
