Detached family house, Trnava
Svoboda, Jan ; Vlach, František (referee) ; Müller, Jan (advisor)
The present Bachelor’s thesis deals with the design of a house in the municipality of Trnava near Zlín. It is a two-storey house with a built-in garage on the first above-ground floor. The house was designed for a four-member family. On the first above-ground floor there is a north-facing hall that adjoins a garage and a staircase area. The open-concept kitchen-living room faces south. The basement of the house represents the living area and it locates a west-facing bathroom of the children, a boiler room, and an east-facing bathroom of the parents. Three bedrooms, two for the children and one for the parents, face south. The peripheral wall constructions are made of surface-ground ceramic brick with external thermal insulation composite system. The horizontal structure is made of reinforced concrete monolithic plate. The building has a pent roof with the slope of 5°. The Bachelor’s thesis is made in the form of detail design documentation.

System for Recognition of 3D Hand Geometry
Svoboda, Jan ; Mráček, Štěpán (referee) ; Drahanský, Martin (advisor)
V posledním desetiletí došlo ke zvýšení zájmu o užití 3D dat k biometrické identifikaci osob. Možná vůbec největší výzkum proběhl v oblasti 3D rozpoznávání podle obličeje, přičemž je v současné době dostupných vícero komerčních zařízení. V oblastni rozpoznávání podle 3D geometrie ruky byl v minulých letech proveden určitý výzkum jehož výsledkem však nebylo žádné komerční zařízení. Nezávisle na tomto výzkumu se v posledních letech velmi rozšířil trh s cenově dostupnými 3D sensory, což potenciálně umožňuje jejich nasazení v mnoha typech biometrických systémů. Hlavním cílem této práce je vytvořit funkční vzorek bezdotykového systému pro rozpoznávání osob podle 3D geometrie ruky, který bude používat novou levnou kameru RealSense 3D vyvíjenou v současné době firmou Intel. Jedním z problémů při použití RealSense kamery je její velmi malý form factor, který je příčinou nižší kvality výsledných snímků v porovnání s velmi drahými alternativami, které byly použity v již dříve zmíněném výzkumu 3D biometrických systémů. Práce se snaží analyzovat robustnost různých 2D a 3D příznaků a vyzkoušet několik různých přístupů k jejich fúzi. Rovněž je vyhodnocena výkonnost výsledného systému, kde je ukázáno, že navržené řešení dosahuje výsledků porovnatelných se state-of-the-art.

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.

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.

Architecture Information for LLVM Compiler Optimizations
Svoboda, Jan ; Dolíhal, Luděk (referee) ; Hruška, Tomáš (advisor)
Tato práce se zabývá automatickou extrakcí informací o architektuře procesoru z jazyka CodAL. Získané informace jsou využity jako základ pro cenový model optimalizátoru překladače LLVM. V rámci práce vznikl nový systém, který vytváří cenový model, převádí jej do C++ kódu a sestavuje do dynamické knihovny. Tato knihovna je za běhu načtena překladačem a využita pro přesnější rozhodování o přínosech jednotlivých optimalizací. Výsledkem práce je průměrné 14% snížení velikosti strojového kódu programů a až 68% zlepšení výkonu generovaného kódu.

Technical viscous curve for injection molding
Hejkalová, Anna ; Svoboda, Jan (referee) ; Kandus, Bohumil (advisor)
Injection molding is highly dependent on flow qualities of plastics. The bachelor thesis compares the conventional measurement of their rheological attributes with the method of injection molding to the technical viscous curve. This method enables to determine the optimum injection rate at which injection resistance does not allow significant improvement of the melt’s flow attributes, on the contrary increases the energy consumption of the process. At the same time, the thesis tries to prove the advantage of this method.

Sensorless velocity control and positions of d.c. low-power brush motor
Svoboda, Jan ; Hanák, Pavel (referee) ; Prajzner, Václav (advisor)
This bachelor's thesis focuses on sensorless control of low load brushed DC motor that is used in the actuators made by the Honeywell company. The first part provides an introduction into motor control and common used methods of speed and position sensing of brushed DC motor. Sensorless method of sensing described in this work is the detection of commutation pulses from the signal of motor current. These pulses are caused by brushes leaping over the commutator bars. Correct evaluation of commutation pulses can provide the information about velocity and position of the motor. This relatively new method of detection of commutation pulses is investigated and arising problems are demonstrated on measured samples of signal. Suitable methods of signal processing are then proposed. Infallibility of these signal processing methods is then proved on the set of signals measured under circumstances of supply voltage and abrasion. Then it is decided which signal processing method that sensorless control system can use is the best.

Wireless connections for metropolitan networks
Svoboda, Jan ; Tejkal, Vladimír (referee) ; Šporik, Jan (advisor)
This Master’s thesis analizes technologies suitable for metropolitan area networks. In this thesis there are mentioned technologies used for wireless transfer with speeds above 1 Gbps. There are described basic features and parameters of microwave radio relay links in 70/80GHz range and free space optic links. These technologies are compared with classic optical networks. Practical part of thesis was focused on development of application which calculates signal attenuation caused by the passage of the atmosphere for both technologies. Results gained from this application are mentioned in this Master’s thesis.
