Interactive Design Coordination for the Building Industry
(1970-06)The problem of effective communication in the process of building design and construction is widely recognized. The involvement of several design disciplines combined with the tendency for designers to work in distinct ... -
Description and Flow Chart of the PDP-7/9 Communications Package
(1970-07)The PDP-7/9 Communications Package was written to provide data transfers between the buffer controller (PDP-7 or PDP-9) of an ESL Display Console and a host computer via a 50-kilobit serial Dataphone link. Initially, only ... -
File Management and Related Topics, June 12, 1970
(1970-09)The subject of these notes is file management. We will develop the problems of file management within the environment of a large information and computing service, often called a computer utility or general purpose ... -
Use of High Level Languages for Sytems Programming
(1970-09)(This paper is a slightly edited version of a transcript so that it still contains the colloquial flavor of the oral presentation.) I'm going to talk about languages for systems programming what they can do for us, and ... -
A New List-tracing Algorithm
(1970-10)List-processing systems have each allowed use of only a single size and configuration of list cell. This paper describes a system which allows use of arbitrarily many different sizes and configurations of list cell, ... -
Pseudo-random Sequences
(1970-10)The purpose of this paper is to study some notions of randomnes for infinite sequences of 0's and 1's. -
Automatic Code-generation from an Object-machine Description
(1970-10)This memo outlines the basic elements of a macro code-generating system, and develops an informal machine-independent model of a code generator. Then the memo discusses how an implementation of this model could be set up ... -
A Computer Model of Simple Forms of Learning
(1971-01) -
Helping People Think
(1971-04)Everyone, today, is familiar with the use of machines to ease physical burdens. Since the dawn of civilization, man's progress in gaining control over his environment has been largely determined by the power and sophistication ... -
The Relational Approach to the Management of Data Bases
(1971-04)The ultimate goal of Project MacAIMS (MAC Advanced Interactive Management System) is to build a computer facility which will be able to support non-trivial decision making processes. (See reference 4). In the early stages ... -
The Macaims Data Management System
(1971-04)MacAIMS (MAC Advanced Interactive Management System) is a relatively small research project that was initiated in the summer of 1968 to investigate the feasibility of using some of the then existing computer facilities at ... -
Complexity Measures for Programming Languages
(1971-09)A theory of complexity is developed for algorithms implemented in typical programming languages. The complexity of a measuring a specific type of complexity is a complexity measure -- some function of the amount of a ... -
Economy of Descriptions and Minimal Indices
(1972-01) -
SIM360: A S/360 Simulator
(1972-05)Modern, large-scale computer systems typically operate under the control of an operating system or executive program, and reserve for the exclusive use of the operating system a set of privileged instructions, which the ... -
The Emptiness Problem for Automata on Infinite Trees
(1972-06)The purpose of this paper is to give an alternative proof to the decidability of the emptiness problem for tree automata, as shown in Rabin [4]. The proof reduces the emptiness problem for automata on infinite trees to ... -
Construction Heuristics for Geometry and a Vector Algebra Representation of Geometry
(1972-06)Heuristics for generating constructions to help solve high school geometry problems are given. Many examples of the use of these heuristics are given. A method of translating geometry problems into vector algebra problems ...
