Features
A multiprogramming environment for online data acquistion and analysis
An experimental system for acquisition and analysis of large bodies of data derived from scientific experiments is described. Its architecture and implementation is…
The LACONIQ monitor: time sharing for online dialogues
The LACONIQ (Laboratory Computer Online Inquiry) Monitor was developed primarily to support non-numerical applications such as retrieval from very large files by means of…
A system organization for resource allocation
This paper introduces a system for resource management using the concepts of “process,” “facility,” and “event.” Except for the…
Algorithms for finding a fundamental set of cycles for an undirected linear graph
Given the adjacency matrix of the graph, the algorithm presented in this paper finds a spanning tree and then constructs the set of fundamental cycles. Our algorithm is…
A SIMSCRIPT-FORTRAN case study
Two programs for a vehicle dispatching model, one written in 7040 SIMSCRIPT and the other in 7040 FORTRAN IV are compared. The comparison is made in terms of basic…
An online, interactive system for text editing is described in detail, with remarks on the theoretical and experimental justification for its form. Emphasis throughout…
Eigenvectors of a 2n × 2n matrix
It has been known that the eigenvalues of a certain 2n × 2n matrix can be obtained by use of two smaller matrices of order n which can be easily constructed. An…
The ALCOR Illinois 7090/7094 post mortem dump
A dump technique for programs written in ALGOL 60 is described. This technique provides an intelligible analysis of an unsuccessful computation process in terms of the…
On the normalization requirement of divisor in divide-and-correct methods
This paper presents an analysis on the normalization requirement of the divisor in a divide-and-correct method. This analysis is made subject to the condition that not…
