Diagnostics and Maintenance Design
Černoch, Adam ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
In the text is given entry of visual inspection about implementation of the selected section in city of Luhačovice. Into forms were plotted failures of the road, determinated their lenght and surfaces. The following describes the evaluation and the cause of failure. After that is given the design and repair of the road. In the theoretical part is written the classification of failures according to TP 82 „Catalogue of flexible pavement failures“. From the cataloque I chose and mentioned important failures that are manifested in diagnosis section. Finally, describes the principles of planning and design of maintenance or repair.

Hydrostatic, deformation and piston pressure gauges
Gregor, Kamil ; Turygin, Andrei (referee) ; Hammer, Miloš (advisor)
This bachelor thesis deals with barometers, especially the principle of their function. The topic of this thesis is hydrostatic barometers, which work on the principle of hydrostatic power; deformation barometers, which measure pressure on the basis of elastic deformation; and finally force barometers, which measure force derived from the pressure applied on a specific area inside the barometer. The first part of the thesis focuses on diagnostics using barometers. An example of practical application of diagnostics is presented, too. In the second part of the thesis there is a practical example of using barometers in diagnostics.

Construction of the station for the diagnosis of damage and leaks from pneumatic systems
Kojš, Denis ; Mazůrek, Ivan (referee) ; Mazal, Pavel (advisor)
Thesis deals with the design, implementation and verification of functionality of station designed for measuring of acoustic emissions from pneumatic cylinders for the purpose of fault diagnosis. The first part of this thesis includes an overview of previous work dealing with the diagnosis of pneumatic systems, also works dealing with the diagnosis of various machine parts using acoustic emission. Further work contains a description of the proposed conceptual design and final draft is described in detail, including occurred complications and their solutions. The last part describes the results of measurements of acoustic emissions from damaged and undamaged cylinders. Functionality of the station is verified by comparing the frequency spectra and envelopes of measured acoustic emission signal.

Artificial Intelligence and Industry 4.0
Kotas, Filip ; Kroupa, Jiří (referee) ; Kovář, Jiří (advisor)
This bachelor thesis deals with search for artificial intelligence methods used in the diagnostics of technical systems. The first part of the work is devoted to the search of used methods in the field of diagnostics of technical systems. The second part summarizes the characteristics and applications of these methods. The conclusion of the thesis deals with the application of the artifical neural network method and the hybrid method „adaptive neuro-fuzzy inference systém“, which is based on the neural network. This part deals with a detailed description and use of these methods in real technical systems.

Diagnostics of Reinforced Concrete Bridge
Rozbroj, Lukáš ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This thesis contains diagnostics of a reinforced concrete girder bridge in the municipality of Újezd u Brna. The aim is to conduct an inspection of the bridge, gather quality photo-documentation of defects and failures and design and conduct a diagnostic examination of such extent that would be necessary for judging the load bearing capacity of the bridge. The result of this thesis is the determined load bearing capacity and a proposal of measures required to keep the bridge functional.

Study of acoustic properties of enclosed rooms
Kovařík, Filip ; Fišarová, Zuzana (referee) ; Šťastník, Stanislav (advisor)
The bachelor thesis deals with the acoustics of enclosed spaces, its behaviour and impact on the clarity and quality of presentation. Here is written transmission of acoustic energy, behaviour of spatial and building acoustics, which builds their diagnostic methods. The work also includes legislative requirements stipulated by the acoustics of enclosed spaces and the achievement of these requirements using different types of acoustic absorption capacity of materials, applications, and more specifically their basic properties. In the experimental part, the measurement of reverberation time in a selected room and the adaptation of acoustic properties so that attained legislative requirements

Assessment of historical building before modernization
Marušák, Lubomír ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This study deals with the evaluation of historic structures, especially historic masonry buildings. It provides information about the current topic of modernization and renovation of historic listed buildings. In the theoretical part are explained specifics of historic buildings in regard to new buildings, materials, which were used previously, types of constructions and all above are described principles of rating existing buildings according to applicable standarts and description of the most common and the most appropriate diagnostic methods. In the practical part are mentioned theoretical knowledge practiced for example the evaluation of historic building of a former court in Zlín. The examination also includes a preliminary probe on selected parts of the structure. The output of my thesis is a documentation of status and failures of court building, preliminary rating of building and a detailed design of diagnostic survey.

Specifics of assessment of old concrete structures
Mička, Michal ; Žítt, Petr (referee) ; Cikrle, Petr (advisor)
The bachelor thesis deals with evaluation of properties materials concrete structures of former textile factory Vlněna from the 19th century in Brno. The content of this work is divided into the theoretical and practical part. The theoretical part deals with the description of the methods used in the research of reinforced concrete structures, comparison of the types of beams used in the past with used today and unlike the principles of the design of reinforced concrete structures in the 1920s and 30s of the 20th century compared to the present time. There are also described components, properties and technologies of concrete production in the period between the war and the comparison with the present time. The practical part consists of on-site examinations and sampling. A large part consists of the evaluation of laboratory tests on the test samples taken from the solved part. A total of 24 test samples were performed. It also compares the strength of the concrete reinforcement with the reinforcement used today.
