Epigraphic Survey Giza

Since 1988 we have been excavating at Giza, 350 m south of the Great Sphinx and south of the gigantic stone Heit el-Ghurob ("Wall of the Crow"). The concession, 650 m north-south and 250 m east-west (16 ha), extends from the bottom of the slope where Zahi Hawass has excavated the "workers' cemetery" in recent years, to the modern paved road and houses of Nazlet es-Semman and Kafr Gebel. A subst...

New discoveries at the interface of boron and carbon chemistries*

The continued growth of polyhedral borane chemistry is illustrated by the successful synthesis of [closo-B12(OH)12] 2– by the H2O2 oxidation of [closo-B12H12] 2–. The hydroxylated species reacts with common organic reagents to produce 12-fold degenerately substituted carboxylate esters, ethers, and carbamate esters. The ether derivatives undergo facile and reversible redox reactions in which th...

MAAYA: Multimedia Methods to Support Maya Epigraphic Analysis

This paper present an overview of a research project integrating epigraphy and computer science, which has developed a number of visual analysis methods for segmentation, classification, indexing, and retrieval of Maya glyphs in ancient codices. The paper summarizes the technical aspects of the methods developed for these tasks, including preparation of source materials, creation of a data repo...
