This manual provides a brief description of the primitives in the computer language PDP 11 LOGO. It is intended to provide a quick reference for users who are familiar with the basics of the LOGO language. (Author/SD)

An analog/hybrid simulation of a Digital Volt Meter (DVM) and an incremental analog-to-digital (A-D) converter are presented. An analog simulation of planar frames is also presented. (MLH)

During the past decade, the scope of information science has been evolving into a broader but better defined area of specialization. In this paper several of the definitions of information science which have been suggested by various professional groups are discussed. The educational objectives of information science are identified, and the…

The Postdoctoral Fellowship Program in Educational Research at the University of Pittsburgh afforded the opportunity for two selected participants to engage in intensive study which expanded their capabilities in the area of research methodology. In addition, the program provided them with extensive research experience. A plan for individual study…

The four papers presented at this weekend school are: (1) "The Effect of the Computer on Libraries" by J. D. Dews; (2) "Machines in a Rural Library Service" by O. S. Newman; (3) "The Education of Libraries in an Age of Mechanization" by D. E. Davidson and (4) "People, Programmes and Problems" by B. J. Perry.…

Ten units in higher education employing computer techniques which used a key measure relecting the relative degree of flexibility available to an institution for scheduling its instructional program are reported upon. Other measures which have been employed are described in the form of a short history of space utilization in higher education and…

This booklet was written to help the mathematics teacher introduce computers through an easy, problem-oriented language. In Section I, a problem is selected and solved in a manner that builds up the use of the language. In Section II, the language is applied to three sample problems to illustrate further the programming techniques presented in…

A comprehensive general reference on computer use, this volume contains reports on the state of the art, data communications, computer techniques, industrial applications, and general data processing. It provides several directories and source lists, including book publishers, professional organizations, and equipment manufacturers. It lists…

Rooted binary trees with weighted nodes are structures encountered in many areas, such as coding theory, searching and sorting, information storage and retrieval. The path length is a meaningful quantity which gives indications about the expected time of a search or the length of a code, for example. In this paper, two sharp bounds for the total…

Written for secondary students, this booklet provides an introduction to several computer-related concepts through a set of six classroom games, most of which can be played with little more than a sheet of paper and a pencil. The games are: 1) SECRET CODES--introduction to binary coding, punched cards, and paper tape; 2) GUESS--efficient methods…

An introduction to the problems of variable-length message transmission in distributed loop computer networks, with a summary of previous accomplishments in the area, begins this technically-oriented document. An improved technique, overcoming some of the inadequacies in presently used techniques, is proposed together with a conceptual model of…

A summary of the initial planning meeting for the Pacific Educational Computer Network (PECN) is presented. Representatives from the United Nations, Australia, Japan, and the United States met to inquire into the feasibility of the proposed PECN. Topics discussed were the status of computing in the Pacific, the technology of a Pacific network, the…

Some of the major results of future goals of an automatic program synthesis project are described in the two papers that comprise this document. The first paper gives a detailed algorithm for synthesizing a computer program from a trace of its behavior. Since the algorithm involves a search, the length of time required to do the synthesis of…

Nine job control language (JCL) procedures for the Rapidly Extensible Language (REL) batch system are presented. The REL system itself is a total software system designed to facilitate communication with the computer in very high level languages. Its goal is an interactive time-shared system, but for a variety of reasons it has been desirable to…

A study was made of several dialects of the Beginner's All-purpose Symbolic Instruction Code (BASIC). The purpose was to determine if it was possible to identify a set of interactive BASIC dialects in which translatability between different members of the set would be high, if reasonable programing restrictions were imposed. It was first…
