Normalised Fourier Coefficients for Cursive Arabic Script Recognition

The article is devoted to the study of inscriptions on the gravestones of Haji Ibrahim al-Uradi, his father, brothers and other relatives. The information revealed during the translation of these inscriptions allows one to date important events from the history of Highland Dagestan. Also we can reconsider the look at some important events from the past of Hidatl. Epitaphs are interesting in and of themselves, as historical and cultural monuments that needed to be studied and attributed. Research of epigraphy data monuments clarifies periodization medieval epitaphs mountain Dagestan using record templates and features of the Arabic script. We see the study of medieval epigraphy as one of the important tasks of contemporary Caucasian studies facing Dagestani researchers. Given the relatively weak illumination of the picture of events of that period in historical sources, comprehensive work in this direction can fill gaps in our knowledge of the medieval history of Dagestan. In addition, these epigraphs are of great importance for researchers of onomastics, linguistics, the history of culture and religion of Dagestan. The authors managed to clarify the date of death of Ibrahim-Haji al-Uradi, as well as his two sons. These data, the attraction of written sources and legends allowed the reconstruction of the events of the second half of the 18th century. For example, because of the epidemic of plague and the death of most of the population of Hidatl, this society noticeably weakened and could no longer maintain its influence on Akhvakh. The attraction of memorable records allowed us to specify the dates of the Ibrahim-Haji pilgrimage to Mecca and Medina, as well as the route through which he traveled to these cities.

Late Nineteenth

Focusing on the lithographic print revolution in North India, this article analyses the role played by scribes working in Perso-Arabic script in the consolidation of late nineteenth-century vernacular literary cultures. In South Asia, the rise of lithographic printing for Perso-Arabic script languages and the slow shift from classical Persian to vernacular Urdu as a literary register took place roughly contemporaneously. This article interrogates the positionality of scribes within these transitions. Because print in North India relied on lithography, not movable type, scribes remained an important part of book production on the Indian subcontinent through the early twentieth century. It analyses the education and models of employment of late nineteenth-century scribes. New scribal classes emerged during the transition to print and vernacular literary culture, in part due to the intervention of lithographic publishers into scribal education. The patronage of Urdu-language scribal manuals by lithographic printers reveals that scribal education in Urdu was directly informed by the demands of the print economy. Ultimately, using an analysis of scribal manuals, the article contributes to our knowledge of the social positioning of book producers in South Asia and demonstrates the vitality of certain practices associated with manuscript culture in the era of print.

Arabic Script

The Malay people made Arabic as the medium of instruction in the form of writing by the Malay community. The use of this script is known as Malay Arabic script by adding some Arabic letters by adjusting the sound with Malay language. The first stage of this writing as a communication in trade between the people of Indonesia with Arab traders, then the writers use it as script writing in Malay language. This writing continues to use it as the medium of instruction in Islamic education and teaching to the public. Then the scientists and scholars use it as well as writing characters in writing religious books such as fiqh, tafseer, hadith and tarekat and other writings. After that Malay Arabic script has become a national script of Malay society, including in Indonesia. The Malay Arabic script was used as a newspaper and magazine literature until the arrival of Europeans to the archipelago. Slowly after that Malay Arabic script is no longer used as a national writing script by Malays society including Indonesia.

Magnetic Induction Tomography

Background: Image reconstruction of magnetic induction tomography (MIT) is a typical ill-posed inverse problem, which means that the measurements are always far from enough. Thus, MIT image reconstruction results using conventional algorithms such as linear back projection and Landweber often suffer from limitations such as low resolution and blurred edges. Methods: In this paper, based on the recent finite rate of innovation (FRI) framework, a novel image reconstruction method with MIT system is presented. Results: This is achieved through modeling and sampling the MIT signals in FRI framework, resulting in a few new measurements, namely, fourier coefficients. Because each new measurement contains all the pixel position and conductivity information of the dense phase medium, the illposed inverse problem can be improved, by rebuilding the MIT measurement equation with the measurement voltage and the new measurements. Finally, a sparsity-based signal reconstruction algorithm is presented to reconstruct the original MIT image signal, by solving this new measurement equation. Conclusion: Experiments show that the proposed method has better indicators such as image error and correlation coefficient. Therefore, it is a kind of MIT image reconstruction method with high accuracy.
