We present an interactive method to restore severely damaged historical parchments. When damaged by heat in a fire, such manuscripts undergo a complex deformation and contain various geometric distortions such as wrinkling, buckling, and shrinking, rendering them nearly illegible. They cannot be physically flattened due to the risk of further damage. We propose a virtual restoration framework t...

Historical documents contain facts that family history enthusiasts are interested in extracting. In addition to fact extraction, organizing these facts into disambiguated entity records is also of interest. This paper shows how facts from an excerpt of a page in an OCRed book can be gathered automatically with some expert knowledge.

endowment and its related issues have an age-old history in the history of mashhad and have continued in various forms in different historical periods. the apex of endowment development in mashhad has been in the safavid period, which has been a unique trend in iran’s history. endowment in mashhad has continued in the pahlavi period and of course it has been the continuation of a historical tra...

In this paper, we present an automatic system for the morphosyntactic annotation and lexicographical evaluation of historical Portuguese corpora. Using rule-based orthographical normalization, we were able to apply a standard parser (PALAVRAS) to historical data (Colonia corpus) and to achieve accurate annotation for both POS and syntax. By aligning original and standardized word forms, our met...

Here it is shown that chaotic oscillations can appear after a series of period doublings in radiating diffusion flames when the activation temperature is high enough. It is also shown that period doubling cascades appear typically in very small regions and that they may not be observable if one starts with small perturbations of a steady flame.

We prove that the period doubling operator has an expanding di rection at the xed point We use the induced operator a Perron Frobenius type operator to study the linearization of the period dou bling operator at its xed point We then use a sequence of linear operators with nite ranks to study this induced operator The proof is constructive One can calculate the expanding direction and the rate ...
