Checking the accuracy of bending of the material in sheet metal bending machines VanMark
Fara, Michael ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
This diploma thesis deals with surface forming methods, especially accuracy and measurement of sheet metal bending on Van Mark brakes. The aim of the work was to make bends of samples in the range of 30 °, 60 °, 90 ° and 120 °. The size of the bend of the examined samples is influenced by the suspension of the sheet, which is not taken into account in the currently used type of protractor. The samples were then analyzed on two types of measuring devices - tactile and optical. After measuring, results were evaluated and plotted in the appropriate graphs. Based on the measurement results, a new type of protractor was designed, which will make the user's work easier and more efficient.

Accreditation audit in a testing laboratory according to ČSN EN ISO/IEC 17025: 2018
Kallerová, Barbora ; Maradová, Karla (referee) ; Šrámek, Jan (advisor)
This diploma thesis deals with the elaboration of a comprehensive internal audit proposal in testing laboratories for the needs of a Czech company engaged in the production of cleaning products. The aim of the work is to describe the current state in the selected testing laboratory in comparison with the standard ČSN EN ISO / IEC 17025: 2018, including complete documentation determining the scope of the testing laboratory. Subsequently, an internal audit was prepared and carried out, including the preparation of internal audit reports, evaluation and implementation of the conclusions of the testing laboratory. the resulting overview can serve testing laboratories as assistance in preparing for the accreditation audit according to the standard ČSN EN ISO / IEC 17025: 2018.

Measurement and evaluation of the inserts using an optical scanner
Vanek, Richard ; Šrámek, Jan (referee) ; Marek, Tomáš (advisor)
This bachelor thesis focuses on problematics of scanning damaged press dies by an optical 3D scanner. The bachelor thesis starts with a description of 3D scanning, its use in various branches of industry as well as defects that can occur during scanning. This work provides an overview of the methods of 3D scanning and 3D scanners. Another part of the bachelor thesis deals with the procedure of scanning a damaged press die using the optical scanner STEINBICHLER COMET LED 5M followed by processing the acquired data and creating a 3D CAD model. In the final part, the bachelor thesis focuses on comparing and evaluating the obtained data.

Digital Climate II.
Sidlárová, Kristýna ; Jansa, Jakub (referee) ; Šrámek, Jan (advisor)
In the diploma thesis Digital Climate II. I'm dealing with the representation of the relationship between physical and virtual matter. The final presentation will take place via video installation in a non-gallery environment. In the work process, I record my own experience of gradual work with the processes of influencing the physical mass of ceramic clay and virtual mass software interfaces. The subject of the work is a remediation of physical ceramic material, whose raw materiality is supported by its absence of glaze or any other noble surface treatment, which could be considered a certain metaphor of today, beautifying AR face filters on social media, Photoshop and unattainable standards of beauty and falsely promoted products.

Uncertainties of Accurate Length Measurement
Šrámek, Jan ; Brno), Václav Duchoň (ČMI (referee) ; Vdoleček, František (advisor)
This diploma thesis is supposed to inform readers interested in the distance measurements un-certainty on practical issues connected with the solving of these troubles when utilising a frequently used calibration method - the SIP distance meter. This measuring was implemented by the Czech Metrologic Institute, where the author works; therefore he could take advantage of his rich experience as well as experience of his superiors and colleagues. The author regards the national metrological institute (ČMI) as a sufficient guarantee for the hereinafter presented materials, both regarding the professional qualification and from the perspective of formal rightness of this thesis.

Statistical evaluation of dimensional setting the car for 3D measurement
Čada, Michal ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
This bachelor´s thesis proposes a dimensional calibration improvement concept for a newly produced car. Before the dimensional calibration itself, a car must be fit in place – aligned into the main graphical coordinate system. Prevalent method of geometric levelling (3-2-1) upon reference points of the chassis does not meet requirements of the contemporary cars, whose support frames blocks accessibility of these points. Proposed alignment method uses advanced laser measuring systems and software capable of 3D scan processing. Statistical evaluation of measured control variables on the car body this bachelor´s thesis proposes minimal allowance limit, for which this method is possible to viable.

The Gliese First Art High School Series
Delong, Marek ; Šrámek, Jan (referee) ; Zet, Martin (advisor)
This is the pilot episode of secondary art school series. Characters move in a specific environment rather refers to my visual creation, than to create backdrops real environment. The series consists of a network of links to popular music and serial culture, artistic subculture, the world of high school and internet underground visual and fashion scene. I'm not trying to capture the objective state of the art community or high school, this is a subjective view based on my own sources of inspiration that I have described above. It is about 5 minutes. Format pilot episode. This is an animation software created three-dimensional environment.

From sea to summit
Staniczek, Jan ; Solčáni, Ján (referee) ; Šrámek, Jan (advisor)
In my thesis I try to convey strange feelings that are inherently connected with post-anthropocentric, ecological thinking of inter-object coexistence, through an installation of a series of clay speakers. From a theoretical point of view, I rely upon Fisher's conception of weird and Morton's conception of dark ecology, in which I found a surprisingly apt articulation of my own feelings, as well as inspiration for further thinking and imagination. The main points in the otherwise difficult to define direction of my work are the planes of blurring borders, ephemerality of experience and intimate contact with otherness.
