The IBM family of APL systems

A. D. Falkoff
1991 IBM Systems Journal  
Many of these were inherited from VS APL, with or without enhancements.  ...  Thus, the desirability of breaking out of the con- straints of rectangular arrays was recognized very early in the course of the work on APL, and some background work on the subject was steadily main-  ...

A research perspective on computer-assisted office work

A. M. Gruhn, A. C. Hohl
1979 IBM Systems Journal  
We describe tasks that have been computerized, the environment in which automated ofice applications are used, and the reactions of people who use the computer for routine ofice work.  ...  The integrated ofice system of the future that relies upon computerized applications for most routine work will have to be a friendly system that can be used by individuals with a minimum of training and  ...  We have seen hundreds of people with very different backgrounds and requirements approach computer use with a variety of initial reactions.  ...

Anisotropic interaction and motion states of locusts in a hopper band [article]

Jasper Weinburd, Jacob Landsberg, Anna Kravtsova, Shanni Lam, Tarush Sharma, Stephen J Simpson, Gregory A Sword, Jerome Buhl
2021 bioRxiv   pre-print
Using automated video tracking, we derive our data from footage of four distinct hopper bands of the Australian plague locust, Chortoicetes terminifera.  ...  Our results suggest novel interactions, namely that locusts change their motion to avoid colliding with neighbors in front of them.  ...  Letting N i be the number of angles in the i th bin, we compute the entropy index as 2 ln(2πN ) to avoid computational issues with large factorials.  ...

The re-discovery of the fast Fourier transform algorithm

James W. Cooley
1987 Mikrochimica Acta  
However, attention and wide publicity led to an unfolding of its pre-electronic computer history going back to Gauss.  ...  The discovery of the fast Fourier transform (FFT) algorithm and the subsequent development of algorithmic and numerical methods based on it have had an enormous impact on the ability of computers to process  ...  Where similarities exist, they are published here with the kind permission of the Association for Computing Machinery.  ...

Finding facts vs. browsing knowledge in hypertext systems

G. Marchionini, B. Shneiderman
1988 Computer  
Users' information retrieval depends on the cognitive representation (mental model) of a system's features, which is largely determined by the conceptual model designers provide through the human-computer  ...  In this article we present a user-centered framework for information-seeking that has been used in evaluating two hypertext systems.  ...  Results of an experiment comparing versions of Hyperties with and without embedded menus demonstrate the critical role of tasks and users' existing mental **Hyperties was first implemented in APL by Dan  ...

Mixed-initiative, goal-directed dialog in a fuzzy knowledge based consultant system

Thomas Whalen
1988 International Journal of Approximate Reasoning  
representation that have formerly been associated only with non fuzzy expert systems.  ...  EXPERT CONSULTANT SYSTEMS Every human being encounters situations in which his or her knowledge is not sufficient for confident, competent decision making.  ...  A book written by the expert is not subject to these problems, but its focus is fixed, and even the best printed index does not give anywhere near the help in locating the relevant bits of knowledge that  ...

An Alternative Curriculum for Computer Literacy Development

Stewart A. Denenberg
1980 AEDS Journal  
The computer provides (1) a Map (consisting of a Yellow Pages, a semantic network, and a Keyword Index) for searching out computer literacy knowledge and for showing the structure of that knowledge; (2  ...  The design and implementation of an alternative curriculum for computer literacy development (ACCOLADE) is described.  ...  . (2) The use of the BACK and SHIFT-BACK keys to move from notes to the index and out of the file.  ...
