Revealing Invisible Photonic Inscriptions: Images from Strain
Photonic structural materials have received intensive interest and have been strongly developed over the past few years for image displays, sensing, and anticounterfeit materials. Their "smartness" arises from their color responsivity to changes of environment, strain, or external fields. Here, we introduce a novel invisible photonic system that reveals encrypted images or characters by simply ...

متن کاملHidden Inscriptions in the Laurentian Library
Following the discovery of a series of geometric designs on the floor of the Biblioteca Laurenziana in Florence we analyse the “Medici panel”, which consists of a circular rosette containing a set of inscribed elliptical disks, with a view to regenerating the pattern. The geometry is shown to be surprisingly complex. We were able to determine a numerical solution for synthesising the pattern. A...
متن کاملInscriptions, Mathematical Ideas and Reasoning in VMT
In this chapter, we trace collaborative problem solving as an interactive, layered building of meaning among learners working as a small group. Our analytic aim is to investigate how students through their inscriptive signs collaboratively build mathematical ideas, heuristics and lines of reasoning in the VMT environment.
متن کاملA Method for Extracting Text from Stone Inscriptions Using Character Spotting
A novel interactive technique for extraction of text characters from the images of stone inscriptions is introduced in this paper. It is designed particularly for on-site processing of inscription images acquired at various historic palaces, monuments, and temples. Its underlying principle is made of several robust character-analytic elements like HoG features, vowel diacritics, and location-bo...
