Design of clamping device for mass production on CNC milling machine
Blahuta, Jiří ; Foltýn, Jan (referee) ; Svoboda, Petr (advisor)
This bachelor thesis deals with a design of a milling fixture and a fixture for broaching on a press. The fixtures enable progressive production on a CNC machine with a high efficiency and minimal downtime. The fixtures are designed for a serial production of a specific component in automotive industry with quantity of 250 000 units per year. The main goal and partial goals of the thesis were accomplished. The designed milling fixture uses wedge clamps and hydraulic cylinders for clamping. The broaching fixture uses springs to position the workpiece. The design of proposed fixtures was verified by production capacity calculations, which prove that the series will be produced in a required time. To further increase productivity, it was suggested based on calculations to use five milling fixtures in the milling machine. The design of the broaching fixture was verified by FEM simulation, which showed that the device is sufficiently rigid and strong. The result of the work is a design of two fixtures in the form of 3D models and drawings. The work includes, among other things, research of three-axis CNC milling machines, broaching machines, and wrought aluminium alloys.

Technical Analysis
Vetýška, Jan ; Svoboda, Filip (referee) ; Novotná, Veronika (advisor)
Aim of the thesis is the analysis and understanding of issues of technical analysis, namely Woodie CCI trading system. This trading system recognizes whether the market is at the moment oversold or overbought, which is also a draft program which calculates these values and giving us signals to trade. This trading system recognizes whether the market is oversold or overbought at the moment. It is also a draft program which calculates these values and giving us signals to trade. At the beginning it is necessary to give a theoretical viewpoint. There is also described the financial system and other important information.The next section describes the trading system, how it works and why I chose it. The following is the procedure for creating applications and basic knowledge of Visual Basic. Finally, I make a backtest where we will see how the system is in practice.

Broadband services over power lines
Svoboda, Jan ; Martinásek, Zdeněk (referee) ; Stančík, Peter (advisor)
The Bachelor´s thesis is intend on assembly of basic informations from area of PLC systems. It envisages the modern problems in area of communication on the energy supply networks. By the aim is provide compact informations about particular areas of usage PLC systems – both in a household, an automatic exercises and in a possibilities of broadband. The first part of thesis includes the theoretical informations about PLC network. The second part considers by testing of basic parameters PLC network. Of all the made measurements are draw conclusions and valorize the usability of metering devices.

Multifunctional building
Svoboda, Tomáš ; Pospíšil, Tomáš (referee) ; Pěnčík, Jan (advisor)
This is a detached multifunctional building in the construction of commercial and residential buildings. The building is located in České Budějovice. Multifunctional building has five floors, one underground floor and a partial basement. The building is covered single-surface vegetation and double skin roof rack. On the first floor is a multifunctional building with reception vestibule, hall of which are accessible to all businesses and also the staircase space. The first floor is also a cafe, spatially separated from the multifunctional building. The café includes restrooms and stairs to get to the hinterland own cafe, where there is room for staff, toilet and are relevant warehouses drinks and other amenities. On the second floor there is a fitness center with all facilities and sanitary facilities. The gym also includes a reception and a health food store. In the third to fifth floor are residential units. A total of 5 apartments, where 2 and 3 flats are always identical. The building is based on foundation strips of plain concrete and masonry made of POROTHERM building system with a contact system of the company ISOVER. The project has been prepared complete documentation of new multifunctional building at the level of documentation for construction. Design of the building emphasizes the static and layout, fire safety, energy savings and safety in use. Drawing documentation was realized in ArchiCAD.

Transparency of voice and light
Hejduk, Adam ; Tomáš,, Svoboda (referee) ; Ambrůz, Jan (advisor)
The diploma thesis entitled Transparency of Voice and Light presents an audiovisual installation, the theme of which is individual reflection of the environment through the creation of fictional stories. In his work, the author also deals with the possibility of overlaps with own previous works and with the creation of a thematic interconnection. The installation links a set of subjective fictional narratives. The installation is scenographic in nature and represents a platform for telling personal statements and ideas.

Precise segmentation of image data
Svoboda, Jan ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
The concern of this thesis is a development of an extension module for 3D Slicer platform. The core of the module is an implementation of a Support Vector Machines classifier, which is used for segmentation of the vertebral column image data provided by the University Hospital Brno. One of the goals of the thesis was resampling and registration of these image sequences. CT volumes provided solid contrast and were used as a reference for gaining properly segmented groups of vertebrae. Due to the low quality of the MRI volumes image data, segmentation of MRI images was not completely succesful. The extension module scripted in Python language can be seen as a tool and can be used in the future for different datasets.
