Knee Ankle Foot Orthosis with Hydraulic Knee
Vávra, Jan ; Robenek, Dětřich (referee) ; Koutný, Daniel (advisor)
This master thesis deals with the engineering design of a knee-ankle orthosis and subsequent implementation of a functional sample. The subject of the first part of the thesis is the design of internal shape of the shell on the basis of the patient's leg using CAD software. The second part deals with the design of the hydraulic knee. The knee joint with hydraulic controlled bending enables easier movement for patients who are not able to bring up stairs and uneven surfaces than existing joints. In the implementation was used SolidWorks 2012 and Geomagic Studio 12.

The bra in a culturological perspective
Reichelová, Kateřina ; Czumalo, Vladimír (advisor) ; Hubáček, Ondřej (referee)
This thesis is a presentation of the bra in a culturological perspective. It gives an overview of the historical, technological and current socio-cultural context of the garment and suggests an empirical study that would help to answer the question why women wear bras. The bra is a cultural element that is perceived by most people living in current western society as an integral part of everyday life. For many women it is an essential component of their wardrobe. However, it plays more roles than that of a practical "gadget". The brassiere is, in its own way, a social phenomenon; a multidimensional entity that can be viewed from many different angles and in different contexts. The thesis compiles basic information on the origins, evolution and functions of the bra. The first part presents the most important milestones in the history and development of clothing of the shaping of the female bust before invention of the bra. The second part of the paper presents the evolution of the bra as an element of the material part of current western culture. Section three considers the changes in attitude toward the brassiere and its symbolism during the 100 or so years of its existence; namely in the framework of the women's emancipation movement and the feminist/gender discourse. It focuses on three periods: the end...

Structure and dynamics of shell sources in general relativity
Turnovec, Aleš ; Žofka, Martin (advisor) ; Langer, Jiří (referee)
Cylindrically symmetric shell sources are studied and a general form of induced energy-momentum tensor of a collapsing shell is presented. The actual movement of the shell is numerically solved for a case when dynamics of the system is determined by energy conservation per unit length. It is then shown that additional assumptions can prevent the collapse, e. g. induced energy-momentum tensor as perfect fluid or null dust of counter-rotating particles. Collapse can be prevented also by introducing Thorne's C-energy into the system.

Coherence-controlled holographic microscope in cell's life cycle research
Křížová, Aneta ; Kozubek,, Michal (referee) ; Uhlířová, Hana (advisor)
The goal of this diploma thesis was using of a coherence-controlled holographic microscope in cell’s life research. A brief history of interference microscopy and it’s applications in biology is described. Also other microscopy techniques routinely used for transparent objects imaging are mentioned and the biology of cell’s life cycle briefly explained. Characteristics describing the shape of a cell were proposed and tested with respect to identification of particular phases of its life cycle. The method of dynamic phase differences was modified in order to distinguish the internal motion of cell’s mass from the movement of the whole cell. Selected characteristics were used to evaluate observations carried out with the holographic microscope and the possibilities of their further applications were depicted. In conclusion, obtained findings were summarized and modifications of microscope construction as well as data-processing software were suggested.

CIRCULATION
Bartošová, Zuzana ; Vlasák, Robert (referee) ; Ambrůz, Jan (advisor)
The diploma project Circulation tries to solve the problem of repeating cycles. It is an object with organic shape, created from a tube with light circulation on it. This object is based on idea of human constantly repeating actions and processes, whether they refer to the human body and mind, nature or society. The object is created site-specifically in to the gallery (Brno Gallery OFF/FORMAT) and tries to fill the space. The line passing through the gallery space can be seen as a route or path, but it can also remind a movement without a clear goal, or go around in circles. The omnipresent cycle, is then an individual contribution to the whole and it can be presented as a irregular curve full of dramatic twists and turns, ups and downs. The light (made by digital LED strip), which constantly copies the organic shape of the tube, represents an endless flow of information. The object tries to point out the never ending circulations in our lives; the object does not solve the problem, it is rather a statement.

The role of beauty in Plato's philosophy
Gál, Ota ; Hlobil, Tomáš (referee) ; Špinka, Štěpán (advisor)
The final thesis aims to develop the question of beauty in Plato. To do so, it tries to gain a proper interpretative access to Plato`s dialogues in the first chapter, and concludes that as they are principally unified on the basis of the likeness of the cave, they can be separated into three structurally different groups with distinct purposes - elenctic, anabatic and katabatic. The second chapter analyzes the dialogue Hippias Major, and traces the ontological implications of its negative outcome, as well as suggestions in relation to which other notions Plato tried to develop his conception. It then analyzes the dialogue Phaedo and tries to reconstruct the basics of Plato's theory of forms, beauty being one of them. The third chapter analyzes the question of beauty in the dialogues Symposium and Phaedrus in more detail, i.e in relation to love, good, happiness, begetting, soul and speech. Beauty is said to be shining both as form and in body, and eros can thus be mistaken in the source of its excitement. Most importantly the erotic movement of the soul is described as partner. It unifies the tripartite soul, different souls, including divine ones and, to a certain extent, even the soul and corrporeality. These analyses unravel in the fourth chapter beauty as, at the same time, cause and purpose of a...

Post-synthesis synthesis: Czech kinetic art of the 60's and the following creative techniques of its protagonists
Sloupová, Andrea ; Havránek, Vít (referee) ; Klimešová, Marie (advisor)
The study analyses situation on Czech, formerly Czechoslovak, art scene during 70's and 80's of the twentieth century in context of the progress of kinetism. It addresses the question whether and how the kinetism as a synthesis of visual arts, architecture, theater, film and music but also science and technology has been promoted after the demise of the group of the same name. The study is divided into the three basic parts. After introducing the problem by attempt to delimit the kinetism on conceptual and temporal basis the first part follows the initial, rather sporadic, attempts of capturing the motion in the visual arts in a period of the first half of twentieth century. The substantial focus of this part is on the work of Zdenek Pesanek. The second part provides a brief insight by comparison and references into the aggradizement period of international kinetism that occurred in the 50s and through to 70s. In parallel with movement in the West it follows two particular groupments of kinetists in the Eastern block - the Muscovite group called Dvizhenie and the Prague's group Synthesis. The last, essential part of the study concentrates on several Czech personalities from 70s and 80s whose approaches of handling the topic represent various types of kinetism - luminodynamism and luminodynamic environment,...

Ant Colony Simulation
Henek, Štěpán ; Brom, Cyril (referee) ; Bojar, Ondřej (advisor)
The aim of the paper is to design and implement simulation environment, which will imitate the foraging behaviour of the ants. The environment itself is variable. The changes of environment can be purely random, with random element or purely deterministic. Ants should be able to react to these changes and adapt to new conditions. An ant's movement is nondeterministic influenced by its current surroundings and genetic information. Finally, our model is compared to the behaviour of real ants in artifitial settings.

Computational modelling of interaction between oscillating vocal folds and air flow
Pavlica, Ondřej ; Matug, Michal (referee) ; Švancara, Pavel (advisor)
Master thesis deals with creating numerical model of the human vocal folds. Calculation algorithm includes interaction between vocal chords and the air flow. Modal analysis of structural and acoustic environment, backround research of vocal folds function and summary of some published overviews of numerical models are parts of this work. Analysis of the results achieved by the numerical simulations and calculations are focused on the pressure and velocity conditions in the areas under vocal folds, between vocal folds and above vocal folds. Movement and stress analysis of individual layers of vocal folds has been made. Impact of tissue thickness on resulting behaviour has been assessed.

Several utilities for comfortable control of interactive graphical interface
Kolář, Petr
Standard MATLAB libraries do not include some tools for interactive figure processing, even if such functions are common in other graphical programs. Therefore we developed following graphical utilities: i, precise interactive selection of a figure area, ii repetition of a press-button function, iii movement of zoomed figure by slides and iv interactive graphical editor of cursor and button icons.
