Introduction to the Works of Rodney C. Wingrove: Engineering Approaches to Macroeconomic Modeling

A continuous-time control model was formulated and fitted to macroeconomic data by an expert control engineer who worked at NASA-AMES in the 1980s, Rodney C. Wingrove. Two articles were prepared and made available to the aerospace industry at that time, however the authors feel that wider distribution of his study posthumously is warranted at this time. This introduction to the two Wingrove articles that follow provides background information on the technologies Wingrove was working with, as well as subsequent developments in both macroeconomic and engineering modeling and analysis technology. Our purpose is to stimulate further research along the same lines which can potentially lead to structural and/or policy rule improvements that can prevent the extremely turbulent abberations that have been seen in recent years, and promote steady growth with low inflation and low unemployment in a sustainable way. Of particular concern is the exploding national debt problem.     

Comments, with reply, on `A noninvasive architecture to monitorreal-time distributed systems', by J. Tsai et al

The commenter maintains that the above-titled article (see ibid., vol.23, no.3, p.22-3, 1990) on unobtrusive real-time system monitoring fails to demonstrate much appreciation for the software side and as a result provides a somewhat misleading view of the state of the art in real-time system monitoring. He states that the article fails to mention that modern real-time application software written in a high-level programming language rarely conforms to the static structure assumed by the monitor. The authors reply that their article clearly states that the principal objective is to develop a hardware-based noninvasive real-time monitoring system to ensure minimal interference in the execution of a target real-time distributed computing system. They point out that the monitor does not assume that the application software has to be a static structure and present an argument in support of this claim
