FROM EAST TO WEST: RELATIONS, COLLISIONS, AND DIVERGENCE OF CZECH AND JAPANESE CULTURE
Vaculík, David ; Čapková, Helena (referee) ; Mitášová, Monika (advisor)
The diploma thesis follows up the pre-diploma research dealing with the investigation of selected literature on Japanese traditional and modern architecture and gardens, archival research of extant 20th century buildings in Czech republic influenced by Czech-Japanese relations and the contemporary perception of Japan in the eyes of the Czech professional and uninitiated audience. It also includes a selective glossary of Japanese words and terms, containing study translations from English of selected architectural literature related to the topic. The output took the form of a Discovery Book with a short glossary, pictorial data and an anthology of translated texts. The thesis follows this preliminary "introductory research" with two main parts. The first part (A) explores concepts of space-making and spatial elements deeply rooted in Japanese traditional buildings as they were rediscovered and rethought, particularly by 20th century Japanese architects – who continued to use and revive these concepts in their own work. The text traces their understanding of Japanese traditional architecture. Then, using the example of three Japanese traditional spatial "icons", four works by 20th century Japanese architects, and three works by Czech architects in different phases of the 20th century, the thesis probes the relationship between these two architectural cultures in a European context. The second part (B) consists of texts on the architectural designing of model, utopian housing. The whole design follows a narrative – a scenario that shapes a temporal and spatial sequence that is not in line with the classical perception of time and space but spirals upwards. The next subsection interprets this story into spatio-temporal gradients and elements. Parts C and D contain conclusions and literature used. Model buildings are proposed on a range of scales: the smallest dwelling (a capsule), minimal dwelling, community dwelling, house, villa, city, and a coffin. The composition of the different scenarios and structures respects the movement along a spiral, where we can also observe the cyclical nature of life itself, which ends with the last terminal phase that escapes the gradient of scales – the coffin. These individual proposals are inspired by the studied phenomena and elements, texts and buildings of Japanese and European architecture with their interrelationships. The aim of this thesis is first to study the spatial, temporal, but also light and colour possibilities of Japanese traditional and modern architecture in the context of European, especially Czech, ones. Another aim is to propose a model-based, utopian housing project with a gradient layering of spaces, structures, materials, views and lighting based on various game strategies as well as the maxims of “Form follows fiction”.

Application Database Layer Generator
Kuboš, Jaroslav ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This diploma thesis deals with the design and implementation of a framework for the database persistence layer development. This framework is easy to use while keeping the code elegance. It supports object oriented programming features such as inheritance and collections. Other features include versioning of objects and lazy loading. The object metadata are obtained through reflection provided by the .NET framework. The framework is not using any literal for identification (classes, attributes) even in object queries. Most of checks are done by compiler.

Alternative Methods for the Analysis of Structural Changes in Muscle Tissue
Kaspar, Pavel ; Hrabovský, Miroslav (referee) ; Adam, Vojtěch (referee) ; Grmela, Lubomír (advisor)
Tato disertační práce se zabývá tématikou analýzy strukturálních změn ve svalové tkáni a metodikou optického měření. I přesto, že existuje nezanedbatelné množství metod pro detekci konkrétních změn ve svalovině, především pak v konzumním mase, drtivá většina z nich se zaměřuje na jeden konkrétní proces a vyžaduje komplikované postupy a drahé přístroje. Předmětem prezentovaného výzkumu není tedy nalézt metody přesnější a specifičtější, než jsou ty již exitující, ale raději zvolit alternativní přístup k problematice. Součástí je pak i snaha najít možnosti jak obejít technologické nároky moderních postupů a přitom se přiblížit co nejvíce jejich informačnímu přínosu. Za tímto účelem je potřeba mít dostatečné teoretické znalosti a experimentální zkušenosti především v oboru fyziky, optiky a postupů měření, ale také široké povědomí o problematice biologických tkání a procesů v nich probíhajících. Na základě získaných informací a pochopení pochodů ve svalové tkáni jsou navrhnuty a testovány tři rozdílné přístupy. Vytvořené metody pracují s fotony v transmisním i reflexním uspořádání. Pomocí pozorování změn absorpce, rozptylu a polarizace světla po interakci se vzorkem svalové tkáně jsou posouzeny jeho další optické vlastnosti především index lomu a optická anizotropie. Identifikace změn optických vlastností vzorků za různých podmínek umožňuje společně se simulací Monte Carlo posoudit rozdíly mezi vzorky čerstvými, starými, sušenými a jednou či dvakrát zmraženými a rozmraženými.

Looking Back
Ivanová, Karolína ; Hládeková, Katarína (referee) ; Smetana, Matěj (advisor)
In my bachelor thesis I will deal with the connection between observation and photography process. I watch how the process of photography is born in its simplest and most basic form and in the initial idea. The first part of my bachelor thesis consists of audio recordings where I capture the everyday moments of interest that I was interested in. I am interested in the relationship between photos by word / language, how the language enters the photo, and vice versa. It is enough to look at the picture and associations and memories and ideas are reflected in words and images. It's about raising "mental" photos in my mind. The second part of my bachelor's thesis consists of a mirror object, which is activated only when the viewer is involved in the observation process.

Analysis of an Electromagnetic Wave on the Boundary between Electromagnetic Materials
Kadlec, Radim ; Lazar, Josef (referee) ; Macháč, Jan (referee) ; Kroutilová, Eva (advisor)
The proposed dissertation thesis contains an analysis of conditions on the boundary between layers having varied electromagnetic properties. The research is performed using consistent theoretical derivation of analytical formulas, and the underlying problem is considered also in view of multiple boundaries including the effect of the propagation of electromagnetic waves having different instantaneous speed. The author presents a survey and formulation of the basic characteristics of methods used for electromagnetic wave propagation analysis; in this respect, special emphasis is placed on radial models. The processing of the topic involved the designing and verification (using a set of different, layered planar materials) of algorithms to analyze the electromagnetic field components. The algorithm was assembled to enable simple evaluation of all components of the electromagnetic field in relation to the speed of the wave propagation in a heterogeneous environment. The proposed algorithms are compared by means of different numerical methods for the modelling of electromagnetic waves on the boundary between materials; moreover, electromagnetic field components in common points of the model were also subject to comparison. When in conjunction with tools facilitating the analysis of material response to the source of a continuous signal, the algorithms constitute a supplementary instrument for the design of a layered material. Such design enables the realization of, for example, recoilless plane, recoilless transition between different types of environment, and filters for both optical and radio frequencies.

Thermal baths Yverdon, five senses in architecture
Lišková, Nela ; Uřídilová, Marcela (referee) ; Koleček, Ivan (advisor)
The spa area is located in western Switzerland in Yverdon-les-Bains, which extends along the southern shores of Lake Neuchâtel. The aim was to replace the current Spa complex which capacity and operationally not meet today's requirements and also to increase capacity accommodation in the form of hotel. New spa complex is placed as solitaire in the area between the spa parks which creates fluent transition between them. Spa function is divided into multiple objects that have their own character, but which in their complexity creates one house. These objects "float" on the surface of the water, unites them and divides its operations at the same time.
