Replacement of human bones by synthetic materials using 3D printing
Svoboda, Štěpán ; Sedlák, Josef (referee) ; Zemčík, Oskar (advisor)
The thesis is divided into three main parts. The first section summarizes the theory of the issue. Here we are unified theoretical information about the various possibilities of different approaches. The result of this part is therefore a general summary of theoretical possible procedures of creation bone implant, where each are listed the advantages and disadvantages. The theoretical part also contains information that ultimately, in practice, the author did not use. But his idea was to create a comprehensive look at the issue from several angles. The second part uses theoretical knowledge from the previous set of information as a basis for defining the steps required to successfully manage the issues of bone 3D printing. The third part will follow the guidelines of both previous and focuses on practical making bones and subsequent evaluation method chosen. There are discussed various steps that led to the final conclusion, making bones and work is then focused on the evaluation of the success of selected procedures and recommendations for future action.

Parameters for 1D Single Cylinder Engine Simulation
Stryja, Štěpán ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The relationship between the 1D simulation and the corresponding input parameters is addressed in the paper. The one-dimensional simulation is demonstrated in the GT-Power environment. The work deals with both experimental and computational analysis of the input parameters. Additive methods of 3D printing of fixtures and subsequent measurement of volumetric flow rates on a Superflow Flowbench SF-260E purge station were used. This procedure led to the final calculation of discharge coefficients. The 3D scanning method, using ATOS 2M equipment, together with subsequent data processing, using the appropriate software, led to the analysis of the valvetrain mechanism and the construction of its kinematics. The practical part was demonstrated on two-cylinder heads of a four-stroke single cylinder engine with a displacement of 125 cm3, with natural aspiration. One of the heads was modified, resulting in volumetric flow increase of 29 % in case of the intake and 15 % in case of the exhaust, compared to the stock head. The work led to the acquisition of key input data for the 1D simulation of the aforementioned engine.

Scanning and evaluation of a patient's hand with Dupuytren's contracture
Dalecký, Jan ; Vosynek, Petr (referee) ; Návrat, Tomáš (advisor)
This bachelor’s thesis deals with development of methodology for determining the angles between joints of the fingers of a patient with Dupyutren’s disease. The methodology works with 3D scan of the hand created with the help of a smartphone and rotating mechanism. Nowadays, the measurement is carried out with the help of a goniometer. However, this measurement is often inaccurate and may not be very pleasant for the patient. The main reason for the research is to improve the quality of the measurement results and evaluate the patient’s condition outside of the time spent in the clinic. An electronic database with the possibility of visual comparison of the patient’s conditions is also an advantage. The angle measurement process takes place on the computer in Fusion 360 and Blender software. Both measurement software and mobile scanning applications are selected to make this methodology as accessible as possible. All applications are freely accessible and user-friendly. The digitally measured values significantly match the real values and even give more relevant results for the evaluation of the severity of the patient’s condition.

Strengthened by Sirens
Nikitina, Pavla ; Horáková, Jana (referee) ; Medek, Tomáš (advisor)
The diploma thesis "Hardened by Sirens" focuses on telling stories through sculptural realisation. These stories are taken from the new phase of the Russian-Ukrainian war that started in 2022. I created the sculptures based on 3D scans as a reportage of events caused by the war. In my work, I followed up on an earlier sculptural project-study entitled "5 Minutes", which was created in 2019 in the context of my bachelor’s studies at FFA BUT. The sub-heading to the study read "3D war reportage ". In the textual part of the master’s thesis, I also focus on the concept of 3D reportage and the various possibilities it offers me as an artist working on the border of the genre of reportage and social documentary.

Approximation surfaces for 3D data
Valachová, Alžbeta ; Novák, Jiří (referee) ; Procházková, Jana (advisor)
This bachelor thesis is dealing with approximation surfaces for 3D data using methods such as RANSAC, least square method and B-spline surface. Its goal is to study and program these methods. First, the methods are described and then the actual programs are analysed. In the end of the thesis, we compare all three methods using data from 3D scanning. Through this effort we can assess their positives and negatives.

Replica of a historical machine gun mount
Doležal, Jakub ; Suchý, Jan (referee) ; Maňas, Pavel (advisor)
This bachelor's thesis deals with the analysis and construction of the Královopolská gun mount replica, which were equipped in selected objects of Czechoslovak border fortifications before the World War II. This work is devoted to the analysis of the original documents for the gun mount, CAD model creation, 3D scanning and modification of scanned polygonal mesh of the heavy machine gun vz.24, which was selected as an example of machine guns mounted in the Královopolská gun mount. This is followed by a virtual compatibility check of the gun mount model with the machine gun model. The production model creation is introduced in next part, using technology with the lowest possible production costs. Complete drawing documentation for the replica production is also part of this bachelor thesis.

Meshes
Pec, Jiří ; Moješčík, David (referee) ; Gabriel, Michal (advisor)
The bachelor thesis deals with the artistic processing of the 3D mesh topology. The object is based on a self-portrait 3D scan and its polygon mesh topology. The realization is made in a steel polygon mesh of the developed body surface, in a way that the individual polygons are loosely connected so that the mesh is flexible as well as human hide.

My Private Collection - "Tetraptych"
Nikitina, Pavla ; Skalický, Martin (referee) ; Gabriel, Michal (advisor)
The bachelor thesis deals with increasing and transfering texture details of abstract paintings into sculptural monochrome reliefs. My collection of 3D detail scans of abstract paintings from world-famous museums served as the basis for my work. The result is four sculptural reliefs created by robotic machining into polyurethane blocks based on the 3D scans.

Anthropometry and 3D scan differences of upper body in resistance trained athletes and soccer players
Čečelský, Jakub ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
The name of this dissertation: Differences between comparison using anthropometry and 3D scanning of the upper body with a power-trained athletes and football players. The aim of this dissertation: Compare the outputs of anthropometric measurements and measurements using 3D scanning for upper body power-trained athletes and football players. Method: The contents of this work was measured antropometri (height, weight, length arm width skinfold, measurement epicondyle, physical circuits) scanning both arms chest. Somatotype was measured using a method of Heath-Carter. Correlation analysis was used to search the potential of the relationship between variables. The sample consisted of 24 subjects in two groups. ST group (power-trained) = 15 probands FB group (playing football) = 9 probands. Results: I summarized the findings of anthropometry and 3D scanning with using literature. Statistical and real significance has shown differences between study groups, and therefore we can conclude that despite similar somatic composition are frictionally trained demonstrably more active muscle on the contrary, we found that the total mass We clearly does not affect the age, size, or percentage of fat that had little effect on intergroup comparison. This means that despite the diversity of sporting focus of the two...
