Situated cognition motivates a review of knowledge maintenance. If knowledge is situated, then a symbolic knowledge base will require modi-cation as the situation changes. We examine the AI and software engineering literature which relates to acquiring and changing programs. Based 5 on a reverse engineering of that literature, we see that strategies have been ooered to maintain diierent types o...

Nonrobustness refers to qualitative or catastrophic failures in geometric algorithms arising from numerical errors. Section 35.1 provides background on these problems. Although nonrobustness is already an issue in “purely numerical” computation, the problem is compounded in “geometric computation.” In Section 35.2 we characterize such computations. Researchers trying to create robust geometric ...

Although from the time of Koch onwards there had been desultory experiments with a variety of gold preparations in the management of pulmonary tuberculosis, gold as a recognised and accepted treatment did not emerge until 1925. In that year Holger Mollgaard of Copenhagen introduced sanocrysin, a double thiosulphate of gold and sodium, with which he had conducted an extensive series of animal ex...
