Deploying expert systems in Ada

As the Department of Defense Ada mandate begins to be enforced actively, interest in deploying expert systems in Ada has increased. A prototype Ada based expert system tool is introduced called ART/Ada. This prototype was built to support research into the language and operational issues of expert systems in Ada. ART/Ada allows applications of a conventional expert system tool called ART-IM (Automated Reasoning Tool for Information Management) to be deployed in various Ada environments with efficient use of time and space. ART-IM, a C-based expert system tool, is used to generate Ada source code which is compiled and linked with an Ada base inference engine to produce an Ada executable image. ART/Ada will be used to implement several prototype expert systems for the Space Station Freedom Program testbeds

ART-Ada: An Ada-based expert system tool

The Department of Defense mandate to standardize on Ada as the language for software systems development has resulted in increased interest in making expert systems technology readily available in Ada environments. NASA's Space Station Freedom is an example of the large Ada software development projects that will require expert systems in the 1990's. Another large scale application that can benefit from Ada based expert system tool technology is the Pilot's Associate (PA) expert system project for military combat aircraft. Automated Reasoning Tool (ART) Ada, an Ada Expert system tool is described. ART-Ada allow applications of a C-based expert system tool called ART-IM to be deployed in various Ada environments. ART-Ada is being used to implement several prototype expert systems for NASA's Space Station Freedom Program and the U.S. Air Force

ART-Ada design project, phase 2

Interest in deploying expert systems in Ada has increased. An Ada based expert system tool is described called ART-Ada, which was built to support research into the language and methodological issues of expert systems in Ada. ART-Ada allows applications of an existing expert system tool called ART-IM (Automated Reasoning Tool for Information Management) to be deployed in various Ada environments. ART-IM, a C-based expert system tool, is used to generate Ada source code which is compiled and linked with an Ada based inference engine to produce an Ada executable image. ART-Ada is being used to implement several expert systems for NASA's Space Station Freedom Program and the U.S. Air Force

When humans using the IT artifact becomes IT using the human artifact

Following Demetis & Lee (2016) who showed how systems theorizing can be conducted on the basis of a few systems principles, in this conceptual paper, we apply these principles to theorize about the systemic character of technology and investigate the role reversal in the relationship between humans and technology. By applying systems-theoretical requirements outlined by Demetis & Lee, we examine conditions for the systemic character of technology and, based on our theoretical discussion, we argue that humans can now be considered artifacts shaped and used by the (system of) technology rather than vice versa. We argue that the role reversal has considerable implications for the field of information systems that has thus far focused only on the use of the IT artifact by humans. We illustrate these ideas with empirical material from a well-known case from the financial markets: the collapse (“Flash Crash”) of the Dow Jones Industrial Average

Crafting a Paper for Publication

The relationship between doing good research and getting the research published is not a causal one. At best, there is a correlation between the quality of a research paper and its being accepted for publication. A research paper\u27s becoming accepted for publication is ultimately a social process, which exists in addition to and is no less important than the content of the paper itself. In this article, I examine how the social process can influence the crafting of a paper for submission to a journal, and re-crafting it in the event that the journal\u27s editor asks for a revision

Invited Paper: Bridging the Gap between IS Education and IS Research: What Can be done to Help?

This article is a written version of the remarks delivered in a keynote address given at the 2018 joint conference of EDSIGCON and CONISAR. The article examines the problem of the gap between information systems education and information systems research. I cover what the problem looks like, three causes of the gap, three ways to bridge the gap, and three long-term strategies

Commentary on “Demystifying the Influential IS Legends of Positivism”

This commentary questions the argument made in the article, “Demystifying the Influential IS Legends of Positivism” (Siponen & Tsohou, 2018). Contrary to the article, this commentary fully accepts that logical positivism as a school of thought in the philosophy of science has fallen into disrepute, points out that the IS researchers who have characterized positivism in their own ways never said that they were following logical positivism, interprets what these researchers had in mind when characterizing positivism in the ways that they did, and ponders what difference Siponen and Tsohou’s discussion on logical positivism actually makes to the future of IS research

ELECTRONIC MAIL AS A MEDIUM FOR RICH COMMUNICATION: AN EMPIRICAL INVESTIGATION USING HERMENEUTIC INTERPRETATION

Recent studies on electronic mail have uncovered evidence of richness in communications using e-mail. This evidence contradicts information richness theory, which has provided the predominant research perspective on e-mail. This paper demonstrates the merits of hermeneutics as a perspective with which to account for the observed richness. The demonstration involves a hermeneutic interpretation of an episode of e-mail communication in an organization

Micro-Structured Ferromagnetic Tubes for Spin Wave Excitation

Micron scale ferromagnetic tubes placed on the ends of ferromagnetic CoTaZr spin waveguides are explored in order to enhance the excitation of Backward Volume Magnetostatic Spin Waves. The tubes produce a closed magnetic circuit about the signal line of the coplanar waveguide and are, at the same time, magnetically contiguous with the spin waveguide. This results in a 10 fold increase in spin wave amplitude. However, the tube geometry distorts the magnetic field near the spin waveguide and relatively high biasing magnetic fields are required to establish well defined spin waves. Only the lowest (uniform) spin wave mode is excited.Comment: 3 pages, 3 figure
