Color Correction for 3D scanner and 3D printer
Kratochvíla, Michael ; Dorazil, Jan (referee) ; Říha, Kamil (advisor)
This thesis deals with color correction of a chain that starts with the 3D Artec MHT scanner, and ends with the 3D printers (CJP – Color Jet Printing technology). In principle, it is necessary to control the color interpretation of the entire chain from the scanning of real models to the 3D print model. With color properties and their color shade, including color textures. The principle of model surface scanning using a 3D scanner is in the same principle as photo camera which scans using a conventional CMOS chip. For this reason, color palettes were scanned using the photo camera and the resulting digital data were analyzed by the Darktable software. This analysis consisted of comparing the scanned color shades of the surface with the spectrofotometer measured data. The main goal of this method was to achieve color precision in the digital data during their acquirement, adjustment and interpretation. Then the same principle was applied to the data acquired by the 3D scanner to create an ICC profile of the 3D scanner. Because the 3D printer (CJP – Color Jet Printing) uses the same principle as the 2D printer, the 2D printing device calibration principle was used again to calibrate it. There have been defined procedures that adjust the color shade to the spectrophotometrically correct shades of the resulting print on a 3D printer. Color swatches were also printed for print quality verification. It has been found that with photo camera, which was used for objective measurement in the L*a*b* coordinates of independent space, any color setting and their adjustment is very sensitive to even small imprecisions. It has been found that it is not easy to obtain accurate colors within the Detla E

Quantification of Relaxation Time T1 in DCE-MRI
Vitouš, Jiří ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
This bachelor thesis deals with methods of T1 relaxation time quantification and B1 magnetic field inhomogeneities corrections. For purposes of the required measurements, the phantom was created using a 3D printer. Firstly the thesis presents information about a given theme, then it hands out the results of measurements taken using standard quantification methods. These methods are consequently analyzed and compared. Next part of the bachelor thesis deals with the fast method based on a variable flip angle (VFA), which needs a magnetic field B1 correction maps to give reasonable T1 estimates. For this purpose, two methods of B1 correction are presented. The first method is a double angle method and second is based on mapping magnetic field B1 using a reference T1 map. To decide which T1 map of which method should be used as a reference, a simple simulation is proposed, which describes the impact of unfavorable effects, such as B1 itself, on the T1 estimate of standard methods. In the end, the conclusions are made and the results of VFA methods are compared with standard methods of quantification.

Color Changing of the Ceramic brick.
Kocmánek, Tomáš ; Zach, Jiří (referee) ; Nevřivová, Lenka (advisor)
The bachelor’s thesis is focused on color correction of brick body. There are examples of pigments commonly used in various industrial fields, as well as studies on the use of waste products as additives in brickmaking industry, altering, among other things, the color of the brick body. In the experimental part of the thesis the effect of three selected ferric pigments and two selected correction clays on the color and selected physico-mechanical properties of the brick body was investigated.

Coaching in the game in football
Mička, Zdeněk ; Buzek, Mario (advisor) ; Tůma, Martin (referee)
Name: Coaching the coach in the game football The aim of the thesis: The aim of this thesis is to analyse the coaching activity of coach in two competitive matches of youth category. During the observation i would like to focus on the types of coach behaviour and his postural activity. Methodology: To achieve the goals I used the method of observation, the method of teaching interaction (ADI) and the method of audio and video recording. Results: The result of this thesis was reached and fulfilled, the research questions were answered. Thanks to this observation i can recommend some advice to another coaches. Key words: coaching, coach, instruction, feedback information, correction 69

Analysis of didactic interaction with selected handball teams
Peerová, Šárka ; Tůma, Martin (advisor) ; Süss, Vladimír (referee)
Title: Analysis of didactic interaction with selected handball teams Objectives: The aim is to analyze the behavior and speech of coaches from various clubs in the female junior category during three matches at a tournament, record the results and then compare their average values per match with each other and with the theory. The final assessment will show values from a truncated system of analysis didactic interaction (ADI) and in particular the ratio of the average values from selected subcategories among the coaches. Methods: We received the data from coaches in the form of a voice recording. The evaluation of the obtained data is numerical forms - tables and graph. Results: According to the theory, coaches should praise their charges and correct their mistakes. This corresponds with the obtained results. During practices, information is relayed using a dominant form of expression and praise is minimal. Also, the rate of correction in comparison to the rate of observation was low. Key words: Coach, match, correction, children, handball, ADI

The behaviour of youth football coach
Maurer, Tomáš ; Buzek, Mario (advisor) ; Süss, Vladimír (referee)
Title: The behaviour of youth football coach Objectives: The objective of this thesis is to present didactic activity of youth football coach, coaching methods that treat the players differently than the training material, define these forms of coach behaviour - feedback information, correction, instruction, question and present examples of effective and ineffective use. Methods: In this thesis I use the method of narrative overview and the modified analysis of didactic interaction. Results: Coaching unlike the style of command breaks down internal barriers and develops independence and responsibility, increases self-confidence and creates a higher level of skills. The coach must be aware of the function and effectiveness of the content and timing of individual forms his behaviour to the training process as efficient as possible. Key words: feedback information, correction, instruction, question, coaching.
