DC motors for general purposes.
Randa, Daniel ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
This work deals with innovation DC permanent magnet motor for low power. The work is divided into three tasks. The first part is to survey serially produced DC motors. The second part is to choose one particular DC motor drawn from the survey and carry out its analysis and detailed description. The last part is to design innovations to selected DC motor.

The Structure of the Atypical Family House in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of master’s thesis is design and assessment of steel load-bearing construction of atypical family house in Vrchlabí. Structure is designed as multi-storey steel structure, cooperating with stiff concrete core. The design was considered in four different options which combines possibility of using steel, steel and timber with different way of stiffness for whole structure. There is also composite steel-concrete alternative floor trimmer for selected option. Design and assessment was conducted in accordance with the applicable standards and by using software Scia Engineer.

Design and analysis of electromagnet
Macek, Pavel ; Skalka, Miroslav (referee) ; Vítek, Ondřej (advisor)
This work deals with a proposal and an analysis of electromagnets. The first chapter is an introduction into solve of the problem. In the second chapter there is a general discussion about basic relations of the electromagnetic field. The third chapter is dedicated to the operation principle and construction of electromagnets and is supplemented with their common classification. The fourth chapter introduces the Finite Element Method and the FEMM programm. The fifth chapter is dedicated to the analysis of the DC electromagnet, the sixth chapter analysis single-phase AC electromagnet. In the seventh chapter there is a review of results of general analysis of both electromagnets.

Defects of insulated facades
Kalousek, Miloš
This paper describes the common defects and faults insulated facades due nepužití cetifikovaných tracks and anchoring. Spot thermal bonds are often underestimated and thus do not meet the design requirements of the Czech standard. Prediction is possible through 3D computer modeling of temperature field, which will help optimization of detail.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Static securing of Ludslavice church
Kovalíková, Mária ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
This thesis is drafting static protection church horizontal pretension, especially at the level of foundations and walls. Furthermore, the design of a new increase the stiffness of reinforced concrete towers and other prestress. The role was also producing construction drawings for the design of static security.

Diagnostic and Reconstruction Design of Brick Building in Medlice
Košárek, Jan ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
Master’s thesis deals with diagnostics and reconstruction of neo-gothic chapel in Medlice. Summary of appropriate testing methods for this chapel is compiled. Visual examination of whole structure have been performed by diagnostics. Masonry element strength was found out at specimens which had were taken out from structure (drill cores and whole bricks). Masonry elements also was tested by Schmidt hammer LB. Mortar was tested by Kucera’s drill. Masonry strength required for static calculation was computed from achieved values. After examination of all structure defects have been designed reconstruction by post-tensioning.

Design of prestressed bridge structure
Otáhal, Ondřej ; Rybák, Vít (referee) ; Klusáček, Ladislav (advisor)
Diploma thesis deals with design of a road bridge over Husí potok in Hladké Životice. The supporting structure of the bridge is designed in three variants, one of which is selected variant post-tensioned slabs. To address the internal forces is used computing software Scia Engineer. In the structural analysis of the bridge structure is assessed at the ultimate limit state and serviceability by European standards – Eurocodes. For chosen variant is prepared drawing documentation and visualization.
