The Official Website of the Research Group
Horáček, Miloslav ; Kobliha, Miloš (referee) ; Jaroš, Jiří (advisor)
My bachelor's thesis deals with creating of a suitable Internet portal of the research group according to the specified requirements of the proposer. This portal will be used in Faculty of Mechanical Engineering and includes specified portal functions e.g. administration of news, publications and animations, diary of events, creating own animations, and collaboration with MathCad. This bachelor's thesis describes all tools which are used for implementation of the web application (PHP, MySQL, CSS, JavaScript, Apache). As an enclosure, an electronic medium with the source codes of the whole application including user's manual is provided.

Fuel Injection Analysis
Schnabl, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The ignition and injection system in any form are an integral part of each car. The development of these systems goes hand in hand with the development of the automobile and his growing industry. Since the nineteenth century to the present occurred in this sector signifcant progress. This thesis is focused primarily on the description of the two systems and their partiton. The development has been recorded from the oldest systems to the newest systems.

Optical Characterization of Thin Films Using Evolutionary Techniques
Horáček, Miloslav ; Bidlo, Michal (referee) ; Jaroš, Jiří (advisor)
My master's thesis deals with creating of a suitable evaluation technique that optimizes the optical parameters of the thin films according to the specified requirements of the proposer. This technique will be used at the Faculty of Mechanical Engineering and it should facilitate the evaluation of measurement results of the The Institute of Physical Engineering workers. Research workers use a digital imaging spectrophotometer for some measurements of optical properties of thin films at the institute. My most important task is to process the output data of the spectrophotometer concerning selected thin film. Construed master's thesis describes all the tools and techniques that have been used for the implementation of the program including evolutionary techniques and basics of the thin films optics (within the framework of the electromagnetic optics). As an enclosure, an electronic medium with the source codes of the whole application is provided.

Analysis of pulse wave propagation in aorta
Holubář, Oldřich ; Janíček, Přemysl (referee) ; Burša, Jiří (advisor)
This master thesis is focused on usage of monitoring pulse wave propagation in aortic system in a field of diagnostic abdominal aortic aneurysm (AAA). There is a description of cardio-vascular system and its pathology in a form of AAA. A summarization of temporary diagnostic method was created and some new methods were proposed. This new methods presume monitoring of pulse wave propagation. Fluid structure interaction (FSI) analyses of pulse wave propagation were performed on simplified models of geometry which representing specific sections of aorta. The goal of these analyses was to prove usage of FSI method in a future development of proposed diagnostic methods.

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.

Numerický model akustických vlastnosti dělící konstrukce dřevostavby
Štěpánek, Samo
The Master's thesis deals with the creation of the numerical model that serves to analysis of the acoustic properties of separating construction of a wooden structure. The work includes theoretical basis for solving the subject, it discusses the airborne sound insulation of separating structures, focuses on wooden buildings, describes a computing environment ANSYS and model creation in it. More variants of model were compiled, CLT panel and frame construction. Model itself is using scripting language APDL and each step of creation is described. The results of numerical simulations describe the distribution of pressure in front and behind the separation construction. Results are compiled into graphs and single value of weighted airborne sound insulation is evaluated. In conclusion individual results of model variants are compared, model accuracy improvements are discussed.
