The Applicability of the JONSWAP Spectrum for Wave Events at Small Water Surfaces
Gřegoř, Adam
Task of the research was to determine whether the spectral density (i.e. spectrum) of wind wave events at Hulínská štěrkovna reservoir is the same as the JONSWAP spectrum, which was based at the wave events at partially developed sea. Data about the time course of the water surface elevation at reservoir were processed with use of the MATLAB and WAFO toolbox that was developed by the Lund University.

Architectural study of the sacral object Brno - Líšeň
Hrubjaková, Petra ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor)
By entering the diploma thesis is to create an architectural study of the sacral object and the Salesian community center in Brno - Líšeň. The first mention of the creating church appeared in 1987 and because of this reason Salesians came to this city, they focus on working with children and youth, according to Don Bosca. Their method od education was reflected in the overall project concept. The building will be linked to the existing object of the Salesian Youth Center, but it will also serve for a wider circle of believers. The consecration of the church will be a third divine person - the Holy Spirit. The object will be on the Horníková ulica, on the parcels no. 5037/30,32. On the plot with parc. No.5037/32 is currently a building, that is the property of the Nadácia pre radosť, and it will by removed during construction. The proposal is based on urban analyzes performed and responds to the surrounding buildings. It also affects the conditions of the building plot and uses terrain sloping. The proposal consists of one object that includes a church with a capacity for 400 seat and 100-standing persons with chorus, sacristy, adoration chapel and technical and hygienic backgrounds. Furthermore, there is a educational/multifunction room, workshop and store of religious products, farther the parish part with the apartments, office for priests and underground garage. In addition to the building, there was created paved areas for pedestrian which responding to existing communications. Due to the removal of the parking lot in the northern part of the solved territory, the existing parking lot was extended on the south side and there was also created a new communication for cars, which connects the Northern Street Horníková with Western. In this communication, it is necessary to create a suitable road signage to prevent the supply of vehicles and it must not be used as an abbreviation in the traffic jam at the 2nd grade road communication.

Brno New Train Station and its Public Spaces
Nytrová, Bohdana ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
For almost one hundred years, Brno has been deciding where the place of a new main train station should be. The works have almost started several times, but the various affairs have always postponed it. Two years ago, it was finally decided that „the River option“ would be constructed. So far, only the technological template has been written – e. g. railway bridge or platforms outline. The thesis focuses on the architectural design of the main building, the roof construction above the railways and spaces below the station bridge. In the design, the outlying urban structures are also dealt with. These include the locations of a bus station, taxi services and bike stands. Moreover, the design also mentions the station’s connection to the city networks. The main motive of the design is to put the main train station building into the centre of the city’s attractions – to make it visible. A boulevard’s view is oriented to the St. Peter’s cathedral – a famous Brno’s building. Just as the mentioned cathedral, the station is important for the city and deserves to be seen. A strong arched construction on four pillars serves as a roof over the railways and places where most visitors are expected to be most of the time. The arch also connects the public transport lines and the bus station. Part of a roof shaped like waves around the main hall connects the structure with the riverside nearby.

Oscilační procesy v magnetických strukturách sluneční koróny
EFFENBERK, Kryštof
This diploma thesis is focused on waves and oscillations in the solar corona, which takes place in a large number of phenomena that occurs here. In recent years these waves have been observed in Earth observation same like as cosmic observation.The task of this thesis is to familiarize with the problems of waves and oscillations in solar corona and subsequent interpretation into numerical simulations that are performed by FLASH code. The aim of the work will be to modify numerical simulations and thus to achieve more realistic of the observed phenomena.

Propagating star formation
Dinnbier, František ; Wünsch, Richard (advisor) ; Brož, Miroslav (referee) ; Naab, Thorsten (referee)
Massive stars are powerful energetic sources shaping their surrounding interstellar medium, which is often swept up into a cold dense shell. If the shell fragments and forms a new generation of massive stars, the stars may form new shells, and this sequence repeats recursively leading to propagating star formation. Using three dimensional hydrodynamic simulations, we investigate fragmentation of the shell in order to estimate masses of stars formed in the shell. We develop a new numerical method to calculate the gravitational potential, which enables us to approximate a part of the shell with a plane-parallel layer. Our main results are as follows. Firstly, we compare our numerical calculations to several analytical theories for shell fragmentation, constrain the parameter space of their validity, and discuss the origin of their limitations. Secondly, we report a new qualita- tively different mode of fragmentation - the coalescence driven collapse. While layers with low pressure confinement form monolithically collapsing fragments, layers with high pressure confinement firstly break into stable fragments, which subsequently coalesce. And thirdly, we study whether layers tend to self-organise and form regular patterns as was suggested in literature, and we find no evidence for this conjecture. Based on our...

City by the Ocean
Holcnerová, Lenka ; Kyselka, Igor (referee) ; Mléčka, Jan (advisor)
In between the Oceans and the Earth (The cities by Oceans) Projects in between the oceans and the earth For studies of towns on the seashores in magister studies under leadership of Ing. Arch Jan Mlecka I was impacted by two basic factors: firstly by my three years of studies and internships in Lisbon – a metropolis on the shore of Atlantic ocean, which became written into Lisbon’s DNA, into its light, tempo, priorities, historz, courage, strength, eternity, simplicity, sailing boats and elegance. And secondly I was influenced by a workshop organized by AA of London in February 2011 in Dubrovnik with lectures of Vedran Mimica and John Palmesino about towns, growth, quality of town life, policies and by studies of Southern Croatian coast under leadership of Krunoslav Ivanišin, where a floating platform was proposed to simultaneously solve several problems of this region. The more I become involved with oceans, the more I am fascinated by shorelines. This rare, dangerous, fractal line is the theatre of the biggest changes and dramas, but it also presents the greatest possibilities. (This is why I call my work not Towns by Oceans but In Between The Oceans and The Earth). When I was mapping shorelines, I have come across several findings: 1. The principles of constructions on shorelines are similar all over the world. 2. There are similar evolutionary stages in usage of shoreline – it is both physical and functional stages. 3. In many cases the potential of ocean is impaired by human interventions. Taking into account these facts, I was searching for further evolutionary stages of shorelines. In Lisbon I visited Ocean Energy Systems where 30 young engineers work on im-provements of machines designed to extract energy from oceans. In order to be effi-cient, these machines have to have giant dimensions. Immediately after seeing a generator on the island of Pico, I realized that such machines should not be put behind fences, creating an obstacle on the rare shoreline in between the sea and the land, but that they must be adopted by architecture – so that we will be able to live with them in symbiosis on the shoreline.
