Shock tube studies of the effects of sharp-rising, long-duration overpressures on biological systems /

Shock tubes have been used successfully by a number of investigators to study the biological effects of variations in environmental pressures (1,2,3). Recently an unusually versatile laboratory pressurization source became available with the capability of consistently reproducing a wide variety of pressure-time phenomena of durations equal to and well beyond those associated with the detonation of nuclear devices (4). Thus it became possible to supplement costly full-scale field research in blast biology carried out at the Nevada Test Site (5,6) by using an economical yet realistic laboratory tool. In one exploratory study employing pressure pulses of 5 to 10 sec duration wherein the times to max overpressure and the magnitudes of the overpressures were varied, a relatively high tolerance of biological media to pressures well over 150 psi was demonstrated (7). In contrast, the present paper will describe the relatively high biological susceptibility to long duration overpressures in which the pressure rises occurred in single and double fast-rising steps.

An analysis of the distinction between deep and shallow expert systems /

This paper analyzes the relationship between the techniques used to build expert systems and the behaviors they exhibit to show that there is not sufficient evidence to link the behavioral shortcomings of first-generation expert systems to the shallow methods of representation and inference they employ. There is only evidence that the shortcomings are a consequence of a general lack of knowledge. Moreover, the paper shows that the first-generation of expert systems employ both shallow methods and most of the so-called deep methods. Lastly, we show that deeper methods augment but do not replace shallow reasoning methods; most expert systems should possess both."
