In several problems considered in the Antenna Laboratory, Cambridge, Mass., the functions fi(x) = x tan * and/2(ac) = x tanh x have arisen. Tables of these functions with the required range, interval of argument, and number of significant figures apparently do not exist; consequently, such tables were computed specifically to satisfy these needs. They were prepared in the form of reports with t...

Scientific documents contain tables that list important information in a concise fashion. Structure and content extraction from embedded within PDF research is very challenging task due to the existence of visual features like spanning cells mathematical symbols equations. Most existing table structure identification methods tend ignore these academic writing features. In this paper, we adapt t...
