Dynamic analysis of an in-line arranged cylindrical chimney
Harazim, Petr ; Kanický, Viktor (referee) ; Salajka, Vlastislav (advisor)
The diploma thesis deals with the response of a steel smokestack structure to wind loads. A detailed computational model implementing the finite element method was created in accordance with the available drawing documentation. The new smokestack was placed next to an existing one, thus it can be assumed that these two structures will affect each other. The thesis also elaborates on the problems of aerodynamic and aeroelastic stability of the earlier smokestack; in particular, the occurrence of vortex shedding in resonance with eigenfrequency of the structure, with the use of the program ANSYS CFX. The evaluation of the structure includes survey of the strength and deflections of the structure. The calculations are in accordance with valid ČSN EN norms.

Sport Centre Brno
Zaplatil, David ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
It is an object of sports equipment, which will be mainly used for ice hockey, as well as for the organization of other sporting and social events. The main objective in the design of architectural buildings were to meet modern requirements for the operation and use of the sports hall. Mass solution hall is designed as part of a hyperbolic curve, which rotates around a central axis. This substance is added next curve and along the perimeter. It is a sine wave, which is twice reflected on the mass of the object. This curve separates the roofing structure from the construction and glazing adds mass element dynamics, which is in my opinion the sporting character of the buildings needed. Construction is due to this curve seems to be constantly moving. This curve has another purpose and that the highest point of the curve are a total of two, is the main entrances to the building and the curve that creates a kind of "entry portal".

Dynamic analysis of structure loaded seismic loads
Janošková, Lenka ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
In this diploma thesis the seismic load on two different models is solved – the first model is a beam hall and the second model is a multistory building. The calculation of seismic load was performed according to standard ČSN EN 1998-1 (Eurocode 8) using the response spectrum analysis and the method of equivalent static forces (substi-tute load). For the combination of seismic responses in different directions are used SRSS and CQC rules. Models and calculations were solved in a student’s version of program RFEM 4.10 (Ing. Software Dlubal, s.r.o.). The comparison of mentioned methods in each models, also the comparison of combinative rules in calculation and the final evaluation of seismic responses on both of models are the subject of this thesis.

The spectral and directional analysis of xylophone, vibraphone and glockenspiel
Hoffman, Pavel ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
Bacherlor‘s thesis deals with spectral analysis and directional characteristics of idiophonic instruments, xylophone, vibraphone and glockenspiel. It analyzes various details during spectral analysis, that could have an effect on the spectrum of a given instrument, and especially on its inharmonicity, thus analyzing its effect on the hardness of mallet, dynamics and the location of the mallet striking the bars (stones, wooden plates). It examines the changes in the harmonic range and the formant areas of instruments. The thesis further describes the mallets, the instruments themselves, theoretical base and the means by which the sound samples were acquired and processed.

Increasing the thermal, electrical and mechanical properties of emergency brakes
Zermegh, Tomáš ; Krejčí, Petr (referee) ; Ondrůšek, Čestmír (advisor)
This thesis is dealing with a detailed analysis of electromechanical brake used in emergency situations to stop the electric motor. Environmental influences, bad material proposal or bad design parameters can significantly limit the behaviour of a brake. The thesis presents several approaches to avoid these limitations, to limit the reaction time and achieve better results. The attached programs can be used either for innovation, or for the new brake design based on the entry requirements.

Revitalization Program of Floral Garden in Kromeriz
Kudlička, Jan ; Matoušková, Petra (referee) ; Mléčka, Jan (advisor)
This project elaborate the foreground of Kvetna garden in Kromeriz.Everything is solucionated like a fluid connection with an old garden.It isssues from the old concept but however has got a new modern and dynamic form.The main idea is to make a pleasure visit for the people who will arrive and give them more knowings about culture ,history and art.

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.

Verification of nonlinear material models
Holada, Jiří ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
The thesis deals with the verification of nonlinear materials during a dynamic test. The reinforced concrete beam is subjected to an impact load. The deterministic finite element model will be developed using several nonlinear material models. The last part describes the sensitivity analysis with MOP (Metamodel Optimal Prognosis).
