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.

Second Nature
Závacká, Paulína ; Zein, Lynda (referee) ; Kristek, Jan (advisor)
The issue of the environment (Umwelt) often fluctuates between two extremes: the cultural environment (architecture) and the natural environment (nature). Although the idea of the "natural environment" can (paradoxically) also be understood as a cultural construct. The project explores the ambiguity of artificial vs. natural through the design of an apartment building. The proposal uses a reinforced concrete skeleton of an abandoned shopping center built at the turn of the 1970s and 1980s, into which it inserts individual "dwellings". The design examines the tools ranging from an "artificial stone" in the form of walls made of shotcrete to dramatic views of the nearby Holedná Forest, which both figuratively and literally (eg. during a walk) becomes another room of the apartments. The landscape and human emotions associated with the natural environment are an important motive for the whole proposal. To expose the tension between two modern tendencies: escape from nature vs. return to nature, it samples the topic of apartment and nature.

BRNO – NEW SOUTH CENTRE LOCATION – POŘÍČÍ, BRIDGES TRINITY, THE AREA OF COMMUNICATION AND SOCIAL INTEGRATION, MULTIFUNCTIONAL OBJECT AND SPACE
Tasch, Daniel ; Obtulovič, Marek (referee) ; Kiszka, Josef (advisor)
The aim of my work was to create a multifunctional house, which serves as a connection between the city center of Brno and its industrial part. This building is also in direct contact with the historic viaduct that would be excavated for this project. Today, this historic viaduct serves as a railway line. However, according to the new KAM proposal, the main Brno railway station is planned to be diverted, so that the viaduct will remain unused. For this reason, it also adds character and interest to the bridge on which I decided to design this project. The houses on the bridges over the river are not something out of the ordinary. They are not built at all to the extent expected. The house on the bridge provides not only a practical connection between the two banks and the use of each place for development, but also an aesthetic pleasure. It is something that is not seen every day.

Reconstruction of overhead power lines 110 kV
Krejčí, Tomáš ; Vašíček, Martin (referee) ; Lázničková, Ilona (advisor)
The master’s thesis deals with the topic new isolation lines of 110 kV. The aim is to propose new insulator hangers. The first, theoretical part focuses on the development of insulators, cutting and possibilities of application. They are the different materials that are used for the production of insulators HV, advantages and disadvantages long rod and cap and pin insulators. There are also described insulator hangers. The theoretical work is to describe thefittings for overhead transmission lines, which are, used to construct a insulator hanger. The last part of the theoretical work is intended distribution towers for overhead lines HV. The practical part deals with the design of new insulator suspensions for specific lines of 110 kV. The results are drawings newly designed hangers and a list of materials (fittings) for individual towers and the total amount of material. The practical part is calculating the differences in the conductor sag using old and new insulators hangers.

Modal analysis of tall slender structures using software GMAST
Hračov, Stanislav ; Pospíšil, Stanislav ; Brůna, Tomáš
The paper is concerned with a verification of modal properties of tall slender structures computed by recently developed software GMAST. Software GMAST determines eigen-frequencies, eigen-modes and corresponding modal quantities of stacks, towers, guyed masts and similar civil engineering structures using slope-deflection method. A numerical model is based on an idealization of the structure as a continuous 2D beam with continuously distributed parameters on elastic supports. Shaft of structure is divided into sections which could be considered as prismatic i.e. with constant unit mass, bending stiffness and static axial force. The effect of guy ropes is introduced in a form of elastic supports with a frequency dependent stiffness. The applicability of the software in praxis is presented on an example of existing structures, for which the numerically and experimentally identified modal properties are compared.
