Scientists are working on the Archimedes Palimpsest digitally produced 700 years old Vaishnava palm-leaf manuscript again with modern imaging technologies. The project, led by PR Mukund and Roger L. Easton Jr., professors Rochester Institute of Technology in Rochester, New York, are digitally preserve the original writings known scientists Sarvamoola-granthas teachers attribute Sripad Madhvacharya (1238- 1317). The collection of 36 works contains his comments on the Sanskrit scriptures and conveys an exposition of his philosophical system (in people Dvaita Vedanta, known for his output from the previous system Sripad Sankaracharya Advaita Vedanta stress).
Mukund became involved in the project as his spiritual teacher in India, the problem of knowledge is expressed and asked him to find a solution. This has been studied for Mukund a personal goal, the Sanatana Dharma and taught and understood for the importance of the document for future researchers. The accuracy of existing printed copies Sarvamoola-granthas is unknown. Mukund sought the expertise of RIT colleague Easton, the Dead Sea Scrolls was ready, and is currently working on the Archimedes Palimpsest. Easton, Chester F. Carlson Professor of Imaging Science Center RIT brought Keith Knox, principal investigator for imaging at Boeing LTS, as a consultant. Mukund added Ajay Pasupuleti, a doctoral student in microsystems at RIT, and the team was formed.The document is difficult to handle and read the result of centuries of inappropriate storage techniques, preservation efforts failed and degradation due to improper handling. Each leaf of the manuscript is 26 inches long and two inches wide (66 cm x 5 cm) and tied together with a cord threaded through twisted two holes. Heavy wooden covers sandwich the 340 palm leaves, cracked and chipped at the edges. Time and misapplication of oil have aged palm leaves dark brown, obscuring the Sanskrit writings.
It is literally crumbling to dust, says Mukund, the Gleason Professor of Electrical Engineering of the RIT. After Mukund, 15 percent of the manuscript is not found. The book was never opened again, unless there is a compelling reason to do so, Mukund says, because every time they do, they lose. Then there is no need to open the book.
The scientists traveled to India in December 2005 in a monastery in Udupi Matha as India is stored to evaluate the document. Supported by a grant from RIT, the team at the monastery in June and spent six days imaging the document of a scientific digital camera and an infrared filter to enhance the contrast between the ink sheet and palm oil. Images of each palm leaf, back and front, were captured in eight to ten sections, then processed and digitally stitched together.
"The picture is very simple," said Easton. The leaves, or what remained of it, was placed on a movable table. As Assemblyman, Pasupuleti spent hours a day. Stitch also has the table a short distance, take a picture and then repeat the process each image a square of two inches (5 cm x 5 cm) summer leaf covers over 7900 digital output images. - Supervised work largely by Knox, several image processing algorithms using Adobe Photoshop and custom software Knox.
This is a very important application of the same types of tools that we have used in the Archimedes Palimpsest, Easton said. Not coincidentally, it was also one of the best projects in my career, since the results are of great interest to many people in India will be.
The images processed Sarvamoola-granthas be stored in a variety of media formats, including electronic media published books and on silicon wafers for long-term archiving. Etching writings on silicon wafers was the idea of Mukund Pasupuleti students. This process, called aluminum metallization for providing an image on a wafer through a negative of the image and to transmit the deposition of metal on the silicon surface. Pasupuleti After each wafer can contain the image of three leaves. More will be needed to store the entire manuscript hundreds of these units. As File, silicon wafers are both durable fire and water resistant, and can be read with a magnifying glass.
Mukund and Pasupuleti return in late November to India to give printed and electronic versions, the monastery in Udupi in a public ceremony in Bangalore, the largest city in the region of Karnataka Sarvamoola-granthas city. We think we were fortunate to have the opportunity to do so, Mukund said. It was a fantastic and profoundly spiritual experience, and all came off clean.Based on the success of this project financing image Mukund other sampradaya Vaishnava manuscripts Dvaita-in Udupi region written since the time of Sripad Madhvacharya sought. the existence of approximately 800 palm leaf manuscripts, some of which are in private collections is calculated.
