This article examines a rediscovered work by the thirteenth-century physician Benvenutus Grapheus de Iherusalem. Surviving only in a late medieval German translation, it contains select recipes and medical procedures. The study of this compilation offers new insight into two important aspects of Benvenutus's life: It provides a more precise dating for his activities, and clarifies at least one facet of his connection to the Levant. An analysis of Benvenutus's sources, most notably the Antidotarium Nicolai but also the Circa instans, confirms the assumption of previous scholars that he had studied at the Salernitan school of medicine. This article also shows that, at least in this particular case, practitioners trained within the Arabic medical tradition did not view Western medicine as a priori inferior. 相似文献

本文全面分析了Pal.King模糊边缘检测算法存在的缺陷,提出了一种新的改进型Pal.King模糊边缘检测算法,并将其应用到AVI视频边缘检测。该算法针对Pal.King算法中对隶属度阈值的设置存在的不足,通过重新定义模糊隶属度函数,反复实验,确定了各参数的最佳值。仿真结果比较显示,改进后的算子复杂度得到降低,效率得以显著提高,边缘检测效果更佳。 相似文献
