Construction of laboratory model "Ball on Spool"
Pohludka, Jan ; Appel, Martin (referee) ; Dobossy, Barnabás (advisor)
This thesis is primarily about designing laboratory model Ball on Spool. The first part of this thesis describes modelling of the system, calculation of parameters, design of the control and simulation, based on which the requirements for the actuator are determined. Secondly, this thesis outlines the design of physical model based on simulation results. All of the components used are described, together with the electrical circuit. Parameters of the physical model are estimated using measured data from experiments. The last part is about designing a control of physical model and its demonstration. This thesis also includes a user manual.

Construction of educational model "Ball on Stick"
Coufal, Ondřej ; Formánek, Martin (referee) ; Dobossy, Barnabás (advisor)
The goal of this thesis was to create an educational model, which could be used as a demonstration of dynamic model and its regulation for future students of mechatronics. The construction was inspired by a similar construction but with much smaller dimensions where most of components were printed by a 3D printer. Afterwards there was created an electrical scheme and implemented on a printed circuit board. For the whole system was designed a caskade regulation, that makes sure the ball will reach the desired position, which is adjustable.

Modeling and control of rear driven axle for Formula Student
Kavec, Matúš ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on design of controll structure of Formula Student monopost. Part of the thesis is a design and subsequent debgging ofthe model so it has the best possible response compared to reality. A PID controller with two degrees of freedom was used to create the control structure. Created controll structure has the task of regulating the system to the required value. By reducing skid, which is often unwanted in race cars, we can achieve better response while accelerating.

Parametrization of PID controller on Mitsubishi PLC
Koláčný, Michal ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
The aim of this thesis is to create a demo application for a brief introduction with the components of the PID regulator. The PID regulator is realized by a function block, which is implemented in a Mitsubishi PLC series iQ-F. The controlled variable is the height of the ping pong ball. The ball is kept at the desired height by changing the air flow rate. The change of the air flow is achieved by changing the motor speed. A propeller is mounted on the motor shaft which blows air into the tube. A SHARP GP2Y0A41SK0F optical distance sensor is built into the tube to sense the actual height of the ball. A model of this system is created and simulated in MATLAB program.The current information about the system is displayed on the Mitsubishi GT-2104RTBD operator panel, where it is also possible to change the sizes of individual parameters of the regulator.

Kvazieuklidovské obory integrity
Čoupek, Pavel ; Šaroch, Jan (advisor) ; Glivický, Petr (referee)
In this thesis, we present an overview of some of the known facts about k-stage Euclidean and quasi-Euclidean rings and domains, certain generalisations of the concept of Euclidean ring, as well as some new results. Among the new results, the norm-free characterization of k-stage Euclidean rings based on a transfinite construction of k-stage Euclidean ring is fundamental and has many applications. Statements providing a way to construct new k-stage Euclidean rings from other k-stage Euclidean rings recieve special attention (with the integral domain case in mind). Also, we present an example of a 3-stage Euclidean integral domain which we believe is a good candidate for not being 2-stage Euclidean. 1

Cell signaling aberrations in primary immunodeficiencies
Fejtková, Martina ; Kanderová, Veronika (advisor) ; Vlková, Marcela (referee)
Primary immunodeficiencies (PID) are genetic disorders characterized by increased susceptibility to infections and various degrees of immune dysregulation. With the expansion of massive parallel sequencing, an increasing number of defects in immune-related genes is being identified in PID. However, the biological impact of the found mutations is often unknown. It is necessary to devise methods to clarify their causality for disease development, which may also aid therapeutic decisions. One of the novel discoveries are gain-of-function mutations in STAT1 gene, resulting in chronic mucocutaneous candidiasis. Candidiasis may be ameliorated with antimycotics or with targeted JAK-STAT inhibitor, ruxolitinib. For our patient with a novel mutation in STAT1, we developed a simple test for the detection of phospho-STAT molecules in peripheral blood lymphocytes. The test confirmed the gain-of-function character of the identified mutation and was used to monitor ruxolitinib treatment efficacy. In the second patient, who presented with lymphadenopathy and immunodeficiency, the as yet undescribed mutation in CASP8 was found. We proved its loss-of-function property expressed as reduced caspase-8 and caspase-3 cleavage, impaired cellular apoptosis, and decreased NFB-related signaling. The third patient who...

Comparison of PID controllers
Prosecký, Jan ; Veselý, Libor (referee) ; Dokoupil, Jakub (advisor)
The work deals with the issue of selecting a suitable discrete PSD controller. The basic types of continuous PID controllers and discrete PSD controllers are shown here. Next, the solution of system identification using Matlab/Ident is described. The tested PSD controllers were a position PSD controller, a PSD controller with differential component filtering and a Beta PSD controller, which was in the settings of the S-PD controller and the PS-D controller. The following methods were used to set the controllers: Ziegler-Nichols, Quadratic integral criterion, experimental settings using the distribution of poles and zeros in the Bode diagram through the Matlab program and the optimal modulus method. Individual controllers are compared by the Matlab/Simulink program in the Automation studio.

Educating model for mechatronics: model development and fast USB communication
Formánek, Martin ; Vejlupek, Josef (referee) ; Appel, Martin (advisor)
Táto diplomová práca sa zaoberá návrhom a realizáciou výukového modelu pre študentov mechatroniky na vysokej škole. Úvod práce sa zaoberá krátkym uvedením do problematiky používania univerzálnej sériovej zbernice a jej implementáciou pre komunikáciu s mikrokontrolérom. Druhá časť je venovaná hardwaru zariadenia, medzi čo patrí voľba vhodného motoru, návrh vhodných elektronických komponentov, návrh dosiek plošných spojov a taktiež mechanickej konštrukcie celého zariadenia. Nasleduje softwarová časť, popisujúca praktickú realizáciu komunikácie, program v mikrokontroléry, a Toolbox, ktorý umožňuje užívateľovi jednoduchú interakciu s hardwarom a to jak z Matlabu. tak zo Simulinku. Kombinácia navrhnutých hardwarových a softwarových prvkov umožňuje jednoduchú cestu k zlepšeniu vedomostí študentov v oblastiach programovania, riadenia a modelovaní sústav. Pre tieto účely je práca rozšírená o pracovný list, ktorý dopĺňa navrhnuté zariadenie o sadu experimentálnych úloh, zameraných na vybrané mechatronické problémy.
