Methodology for supplementing interior exhibitions with technologies for digital objects visualization and content sharing
Získal, Bohuš ; Brůha, Petr ; Macek, Ivo ; Frank, Jiří ; Berka, Roman
The methodology is intended for memory institutions to help them to better understand how modern technologies for digital (especially 3D) objects presentation can be effectively used in exhibitions or expositions. In order to achieve desired presentation functions and formulate specific technical requirements, key parameters of relevant technical components are explained. The main part of the document describes steps important for design, building and running interior expositions or exhibitions. Here a standard process is recapitulated and new activities needed for effective incorporation of multimedia elements are introduced. A particular attention is paid also to the supplier selection process with respect to legal requirements and correct order of steps.

Recommendations for formats of 3D objects and corresponding metadata for the purpose of their sharing, presentation and preservation
Získal, Bohuš ; Berka, Roman ; Frank, Jiří
The methodology presents recommendations for processing, management, sharing and export of 3D digital objects together with corresponding metadata structures suited for presentation and presentation of information objects resulting from digitization processes. These recommendations reflect needs of memory institutions and aggregated databases of cultural content and take into account the relevant legislation. The suitability of existing data formats of 3D models and related metadata is discussed especially from the perspective of their sustainability. The need for development of a suitable strategy of care for digital cultural heritage is discussed together with potential impacts of corresponding decisions and compromises taken. An attention is paid also to conditions for long term preservation of cultural artifacts in digital form.

Directive on multimedia data long-term preservation
Klodner, Michal ; Antoš, David ; Berka, Roman ; Získal, Bohuš
The directive regulates processes and responsibilities during multimedia data preparation for long-term preservation, secure and effective transfer of the data to institutions responsible for long-term preservation and eventual process, how these institutions make the data accessible. The directive focuses on the coordination of processes necessary for potential risk mitigation.

The methodology of preservation and presentation of multimedia data
Získal, Bohuš ; Bohuš Získal ; Cubr, Ladislav ; Berka, Roman ; Svatoňová, Kateřina
This methodology was created within the implementation of the project "Laterna magika. History and Present, Documentation, Preservation and Accessibility ”DG16P02H005 funded by the Program to Support Applied Research and Experimental Development of National and Cultural Identity for the years 2016 to 2022 (NAKI II). The methodology is based on the need to describe the procedures for the description, storage and presentation of digital information objects created during the processing of documentation of historical performances of Laterna magika and to define these procedures in such a way that they are applicable to other works of a similar nature. The methodology responds to a situation where at the national level, and for some specifics of the content or at the global level, there are no defined standards of care for this type of cultural heritage, which would cover all the necessary activities. The above-mentioned specifics include the form of a live performance using technologies and elements, which significantly contribute to the informational and aesthetic form of the work, and the combination of which as a whole is difficult to document. The methodology is intended for memory institutions, their partner organizations or suppliers who participate in the creation, processing, presentation and storage of data generated during the digitization, reconstruction and description of documentation of multimedia performances. Best practices and data structures take into account the situation where physical (data) objects related to works are in the collections of different institutions or individuals, and it is not possible or desirable to collect all physical objects under one common administration. The methodology was verified by the researchers of the project for the Národní filmový archiv, Prague, CESNET and the Institute of Intermedia at CTU FEE on selected data created for the presentation and preservation of historical performances of Laterna magika.

Evaluation the properties of the cutting edge in fusion and flame cutting by solid state lasers
Dočekal, Miroslav ; Berka, Roman (referee) ; Mrňa, Libor (advisor)
The thesis compares oxidation and fusion laser cutting methods in the production of sheet components called Trager consoles. Individual methods of laser cutting are compared in terms of achieved quality and properties of cutting areas. Consequently, the effect of these properties on consecutive technological operations, which are mainly threading and pressing the nuts into components, are evaluated. In the experimental part of the thesis the roughness of cut surfaces was measured and the cuts were classified into quality classes according to the ČSN EN ISO 9013 standard. Metallographic samples were taken in order to measure hardness and determine its course in the direction from the cutting edge into the material. The metallographic samples were further used for capturing detailed images on the microscope and assessing the quality of nuts pressing. Afterwards, the cut moments affecting taps were measured in order to verify the impact of cutting edge properties on threading. These measurements provided sufficient data for comparing the influence of cutting edge properties in individual methods of laser cutting on consecutive operations. Finally, individual methods were compared in terms of production costs. According to all the data and the conclusions reached, fusion method was identified as the most suitable method of laser cutting for components manufacturing.
Laser welding of the abrasive steel
Berka, Roman ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
This project, elaborated within the master degree presents plates welding. Based on the literature study the problems of laser welding were designed optimal welding parameters. The material, on which were in the experimental part test and geometry analysis performed was steel Hardox 400 with thickness 5 mm. These welds were compared with welds made by MAG. Equipment used for werding was fiber laser.
