The Centre of Image and Material Analysis in Cultural Heritage (CIMA) in Vienna and its Current Activities. Part III: Material Analysis

Author(s): Manfred Schreiner,Wilfried Vetter,Bernadette Frühmann,Federica Cappa / Language(s): English Issue: 1/2015

The CIMA-team uses various analytical techniques for the material analysis of pigments and inks as well as the characterization of the parchment: X-ray fluorescence analysis (XRF) for the identification of the elements present and Fourier transform infrared (FTIR) as well as Raman spectroscopy as complementary methods for the determination of the various compounds. The high advantage of these analytical methods is their applicability in air. In most cases the analysis is non-destructive (without taking original sample material) or even non-invasive, which means that no changes or alterations occur before, during or after the investigation at a manuscript. Furthermore, the miniaturization in the field of electronics yielded instruments, which can be easily transported into museums, libraries or galleries. In the publication a short overview of the techniques is presented and some results obtained so far on Glagolitic, Greek and Latin manuscripts is discussed, where different pigments but also ink materials could be identified depending on the origin and period of their production.

Od lokalnego katalogu do globalnej bazy danych. 20 lat komputeryzacji Biblioteki Jagiellońskiej

Author(s): Małgorzata Wielek-Konopka / Language(s): Polish Issue: 65/2015

The presentation of the image of the evolution of the Computer Catalogue of the JU Libraries Collections against the background of twenty years of digitalization of the Jagiellonian Library, included in this article, is an attempt to sum up all the undeniable benefits from applying new technologies and improving digital tools, which concern both the users and the staff of libraries. The gradual elimination of manual procedures in favour of the automatic ones has definitelyimproved the not only the comfort and opportunities of creating information, but also those of searching for it. The interlibrary cooperation in the field of creating and exchanging information, together with the current system of links between digital catalogues, databases, digital repositories, and multibrowsers, have allowed the contemporary library to go far beyond its physical boundaries. Modern technologies and new methods of data presentation constitute a new dimension of access to information. The continuously blurring borders of the form and contents of library materials as well as the geographic boundaries within which information is searched for, provoke thought regarding not only the historical transformations which have already taken place, but also future prospects. What direction should the changes take so that the new philosophy of building library databases meets both the needs of their users as well as the interests of various institutions, and, that the improvements result in the establishment of complete, coherent and factual sources?

The article is about the European Space Agency Satellite Data Dissemination System and the laboratory of the European Space Agency in Burgas Free University. The ENVISAT MERIS instrument (spectrometer with medium resolution) is also considered. The Program fragment, developed in the MATLAB environment, for reading and processing the spectral images with full resolution (MER_FR_1P) and which contains 15 spectral bands is presented. The proposed methodology can be used in many scientific experiments by using the real satellite spectral data distributed by ESA until the end of the ENVISAT satellite mission in 2013. This is realized in realtime, with a delay of 3 hours after the images acquisition
