NAKI2-022 The analysis, description and archiving of aggregate information on the properties of cultural heritage objects and the practical use of this information for restoration, preservation and research
The project objectives include the design and development of devices and systems for the documentation and analysis of collections based on computer-aided visualization and documentation methods and the practical demonstration of their functionality on the digitization of thematic groups of cultural heritage objects. The digital models of collections that are created shall be complemented by information and findings in the form of database records; this information shall be acquired using non-destructive analytical methods (e.g. information on the internal structure, topography, external appearance and element composition of the surface) with annotations consisting of meta-information. This information, combined according to purpose, will allow not only continuous monitoring of surface degradation and detection of possible internal defects but also (in combination with other data) new findings on object development or previous preservative or renovative interventions. Information on composition will be acquired via analyses such as those commonly used in the humanities (historical/archaeological/linguistic/palaeographic, etc.). Within the proposed, purely interdisciplinary project, specialized devices are being developed and various tools are being used for the semantic, visual, spatial and compositional documentation of collections to obtain the maximum amount of information that can be used in practice in the fields of renovation, preservation and, last but not least, research.

GAČR P105/12/G059 Cumulative time-dependent processes in construction materials and structures
The project addresses the assessment of long-term monitoring of environmental influences on selected materials and structures, the consequences of moisture and salt penetration into porous materials, problems with fatigue due to climatic load, and methodology for material and structure assessment in terms of risk reliability.

Completed

NAKI001 Diagnostics of the damage and life of cultural heritage objects
The project objectives included the development of new instruments and associated non-destructive and slightly destructive methods for diagnostics of historical surfaces and the validation of their applicability to the study of the conditions of historical materials and structures as well as quality control and control of the efficiency of renovation and preservation work.

NAKI002 Defects in immovable monuments: knowledge system for analysis, intervention design and prevention
The project aimed to build a knowledge base for documentation and the analysis of defects of cultural heritage buildings, which will help determine the causal links between the defect, the external load and the materials and technology used. Based on the similarity of structures, the technologies used and the character of external influences, the software system will make it possible to identify how probable it is that a risk will occur or a defect will further develop, offering the option to compare the situation in question with similar documented cases and recommending the optimum intervention. The system will provide tools for conservationists, administrators and owners of historical buildings for the documentation of defects in their buildings. At the same time, advanced artificial intelligence methods will provide users with knowledge accumulated in the form of a comprehensive overview of resolved defects, informing them of relevant preventive and renovative intervention techniques based on the similarity to the given case.

NAKI017 Technology for the maintenance and preservation of the Last Judgment mosaic and methods of renovation/preservation of medieval and archaeological glass.
The main objective of the project was the development of a technology for the maintenance and preservation of the Last Judgment mosaic and for its generalization. Partial objectives of the project included the monitoring of mosaic protective layers, a material survey (finding suitable materials and technologies for the protection of medieval glass - mosaics, stained glass, archaeological glass) and finding technology for the application of a protective coating and the verification of its stability.

NAKI027 Unified modular system for remote online monitoring of environmental parameters in depositories and expositions
The proposed project focused on the development of an integrated and, at the same time, modular system for the remote monitoring of cultural heritage objects through the online recording and processing of environmental parameters in depositories and expositions situated in historical buildings, museums, galleries, archives and libraries. The core of the project consisted of the development of a hardware platform and unified data structure which can be combined to enable the centralized processing of telemetry data with continuous monitoring of normal values of the parameters, further complemented by the development of specialized sensors. The general objective of the project was to improve the protection of cultural heritage objects from negative factors such as inappropriate climatic parameters, the presence of volatile organic compounds (VOC) and biological pests.
