Contemporary visitors expect to interact and get more information about exhibition s that they visit by using information technologies. Therefore, in this paper we discuss a system that we developed to enable an improved presentation of some of the most famous cultural monuments in Niš using QR codes. The system allows to easily add inte ractive content for cultural and historical objects, in the form of text, images, sounds, or 3D models. These co ntents can be accessed by using QR codes. The QR codes are implemented as purposelydesigned plates, in accordance with requirements by professi onals from the heritage protection institutions. Scanning of the codes using mobile devices (smart phones, tablets, etc.) provides additional information to visitors in multiple languages and in a variety of multimedia formats. The provided data are about facilities, personalities, and events that monuments mark. The di scussed solution is, using web technologies, made to be cross platform and adaptable to any resolution.

949 941 M30 M33 In this paper we discuss the project of digitization of the Dictionary of the Serbo-Croatian Standard and Vernacular Language. Scanning and character recognition were a particular challenge, since various non-standard character set encoding was used in the course of the almost 60-year long production of the dictionary. The first aim of the project was to formalize the micro-structure of the dictionary articles in order to parse the digitized text of and transform it into structured data stored in relational lexical database. This approach is compatible with several standard structured forms and ontologies (TEI, LMF, Ontolex, LexInfo). A lexical database model was designed in compliance with these structured forms, following mostly the lemon model. Mapping of the lexical entry markers to LexInfo and TEI enabled export of the lexical data to the mentioned formats. A software solution for the dictionary text analysis, parsing and lexical database population was developed and tested on the first and the last published volumes of the dictionary (which contain 27,141 articles in total). An evaluation of the results shows that the developed model and software solution can be successfully used for the other volumes as well.

Triaxial testing of argillaceous rocks and shales is significantly more challenging than conventional rock mechanical testing. The challenges are mainly related to the very low permeability of these geomaterials, and their sensitivity to exposure of atmosphere and brines, which induces variations of water content, suction and effective stress. There are currently no international standards to guide service laboratories for robust testing procedures for shales. A benchmark study of undrained triaxial testing was therefore initiated with three leading service laboratories in shale testing, performing 13 tests and using two different methods of establishing sample saturation prior to deformation. Both methods paid particular attention to minimize volume expansion of the specimens during saturation, and the loading rate during the shear phase in all tests was selected based on intrinsic sample properties and drainage configurations to ensure pore fluid pressure equilibration across the specimen. Opalinus Clay shale core material from the Mont Terri underground research laboratory was used for testing specimens, and intervals on cores were pre-selected on the basis of computer tomography to minimize material heterogeneity. A detailed diagnostic analysis of all tests was performed, and a comparison of the testing results is presented. Good reproducibility of the effective stress paths was achieved by the different laboratories for tests at identical or near-identical initial effective stress conditions. In particular, the test results over a larger range of effective stresses indicate very similar evolution of the fluid pressure during testing and a consistent picture for the derivation of global material properties. On the example of Opalinus Clay, the study demonstrates that robust triaxial testing results can be achieved for shales if some key challenges are adequately addressed. (C) 2020 The Authors.
