Analysis the safety mechanism of the trailers
Pantůček, Michal ; Kubín, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis is engaged in the analysis of a safety mechanism, which is a part of a truck trailer. This mechanism provides a safe and firm connection of a container to the trailer. Primarily abroll containers according to German standard DIN 30 722 are being transported. The introductory part of the thesis deals with the current traffic condition and the accident rate in the Czech Republic. Legislative requirements for safety elements of trailer technology for road transportation are further defined. They are followed by a recherche of industrial solutions for securing mechanisms. Consequently calculations to obtain necessary securing force were performed. An analysis of the mechanism kinematics was carried out then. A structural check of selected mechanism elements was carried out following the kinematics check. Further, an optimalization of a transom design was carried out followed by another structural check. The structural checks were carried out using both the analytical method and the finite element method. In conclusion design documentation was elaborated. This diploma thesis was elaborated in cooperation with the SVAN Chrudim s.r.o.

Physics Simulator for SandBox Type Games
Kotulič, Patrik ; Peringer, Petr (referee) ; Hrubý, Martin (advisor)
This thesis focuses on the creation of a physics simulator of rigid body mechanics. The reader is familiarized with the principles used in current simulators of rigid body mechanics. The thesis then deals with numerical integration of the equations of motion, collision detection and collision resolution. The simulator is presented on a series of experiments. The resulting application can be used as a video game or as a tool for experimentation.

The MEMS sensors usability for position detection
Bobalík, Lukáš ; Sedláček, Jiří (referee) ; Žák, Jaromír (advisor)
Within this Master’s thesis, design and construction of a strapdown inertial navigation system based on MEMS sensors is described. The thesis includes theoretic analysis of physics behind determining the position of an object based on the object’s aceleration and changes in the object’s orientation in space. Included is also an overview of mathematical methods related to the position calculation.

Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.

Measuring unit for race swimmers motion analysis
Kumpán, Pavel ; Hrbáček, Jan (referee) ; Krejsa, Jiří (advisor)
The master’s thesis deals with a design of the computational method for the analysis of swimmers training with the use of an inertial measurement unit. The developed algorithm uses quaternion-based Unscented Kalman filter and merges accelerometer and gyroscope measurements. The proposed method enables analysis of velocity, acceleration and inclination of a swimmer. Verification of the method was based on an underwater video camera capturing and a tethered velocity meter.

Running Motion Analysis
Eliáš, Radoslav ; Kolářová, Jana (referee) ; Goldmann, Tomáš (advisor)
Cieľom tejto práce je analyzovať pohyb a držanie tela pri behu. Systém pracuje so záznamom z dvoch kamier, zboku a zozadu. Využíva nástroj na detekciu postoja ľudského tela založenú na konvolučnej metóde. Práca porovnáva niekoľko detektorov. Výsledný systém používa detektor OpenPose a implementuje knižnicu s výpočtami pre rôzne metriky používane na ohodnotenie formy behu. Výsledky sú zobrazené v multiplatformnej aplikácii. Ohodnotená bola niekoľkými experimentmi na osobnej dátovej sade videí behu.

Point particle kinematics and light propagation in de Sitter spacetime
Michalík, Tomáš ; Hinterleitner,, Franz (referee) ; Larsen, Klaus Bering (advisor)
V této práci se zabýváme de Sitterovou speciální relativiou, která se odehrává v de Sitterově časoprostoru namísto Minkowského časoprostoru. Začínáme studií grupy symetrie de Sitterova časoprostoru. Snažíme se použít tyto poznatky k rozvinutí kinematiky v de Sitterově časoprostoru. Dále přezkoumáváme spojení mezi elektrodynamikou na pevně zvoleném časoprostoru a elektrodynamikou v makroskopickém médiu v plochém časoprostoru. Toto aplikujeme na de Sitterův časoprostor a hledáme index lomu sdruženého média.

Design of dynamic models for traction control of experimental vehicle
Jasanský, Michal ; Porteš, Petr (referee) ; Grepl, Robert (advisor)
The Master's thesis deals with the simulations kinematics and dynamics of experimental four-wheeled vehicle with all-wheel steering and all-wheel drive. Suggestion of vehicle stability systems ABS/ASR for traction control is included. There are several dynamics models with their comparison. The estimation of important vehicle parameters is implemented. Based on knowledge the simple vehicle stability system ABS/ASR is created.
