Reconstruction of a cinema building
Uhrinec, Marek ; Procházka, Martin (referee) ; Sobotka, Jindřich (advisor)
The diploma thesis is focused on a reconstruction of a cinema building in the town Gbely. It’s complete reconstruction of exterior and interior too. Original function, cinema, is change to sport and cultural centrum now. Object is consist of cafe, squash hall, climbing wall and sauna with rest room. Several thermal insulations are used to isolate object and satisfy a norm terms. The foundations are post insulated too. The interior is divided into functional spaces with Heluz system. New finishes in the object is created by brick paving, klinker, ceramic tiles and tiling. All windows and doors are replaced by new ones in the object. Sliding doors are used in interior for save space. The windows and doors are plastic between interior and exterior. All sanitations are replaced by new ones too. The reinforced concrete floor is used instead of lead bearing lintels. The wheelchair conditions are satisfied on ground floor.

Software support of education in cryptography area based on elliptic curves
Szturc, Jakub ; Sobotka, Jiří (referee) ; Burda, Karel (advisor)
The master‘s thesis is focusing on cryptography based on elliptical curves consists of four main parts. The first part provides an overview of the basic cryptographic and mathematical concepts. A key element of this work is the second part which are described in detail the mechanisms of counting two points on elliptic curve and counting point to themselves over the various fields. On this mechanism is based almost the entire issue. In the third section provides the best-known algorithms and protocols for key exchange, encryption and digital signature. The goal of this paper is to devise software to support teaching. This material is created as a web presentation, which described the theoretical foundations and the main characteristics of cryptosystems based on elliptical curves. The whole issue is supported by practical examples of calculations examples, there are also examples for independent work. Additionally, java applets are prepared that allow an interactive opportunity to try the basic parameters of curves, or verify the calculations.

Apartment building
Karafiát, Filip ; Ladomirjáková, Jitka (referee) ; Sobotka, Jindřich (advisor)
The subject matter of this bachelor thesis is a project documentation for an apartment building’s construction in locality of Sadova, Mensikova street in Brno. The building has a basement with 13 parking spaces, a cellar and an utility room. There are four floors with 13 residential units above the basement. Part of the roof of a garage is made as a vegetation and second part is made as a terrace for flats. Main roof of the building is designed as a flat roof with a classic order of layers. The object is designed as monolithical. Garage is solved using columns and gutters, te residential part is solved with monolithic walls. Monolithic reinforced concrete slabs serve as a ceiling. The facade of the building is solved in the ETICS system, in some places, a ventilated facade with PREFA cladding is used.

Security analysis of network protocols
Bednařík, Jan ; Sobotka, Jiří (referee) ; Hajný, Jan (advisor)
The aim of my bachalor’s thesis is security of net protocols analysis. Because of the huge number of net protocols, I’ve decided to choose only a few of them to describe. My task is to describe the TCP/IP model structure in term of security, so I have chosen to devide my thesis into two separate parts. The first part contains describtions of particular TCP/IP layers and adumbration of possibilities of securing. The second part contains more accurate describtions of some chosen protocols, mostly the case of their security. At the close of my work it is my task to describe some utilities and methods which can be used to accomplish an successful attack on chosen net protocols. I have chosen protocols HTTP, FTP and SSL. As the utilities I have chosen programs Wireshark, Brutus and SSLSTRIP.

Conversion of nursery school
Piškulová, Veronika ; Procházka, Jiří (referee) ; Sobotka, Jindřich (advisor)
The diploma thesis deals with project documentation of new kindergartens in the cadastral area Rohatec. The building is self-standing, two-storey with a partial basement. It is a building designed for the upbringing and education of pre-school children. The capacity of kindergarten is 48 children divided into two classes. Part of the operation is a food preparation zone. The building is designed as a brick made of porous concrete blocks with mineral insulation, based on basic concrete passages. The roofing of the kindergarten is using warm flat roofs.

Apartment house
Ladomirjáková, Jitka ; Janda, Lukáš (referee) ; Sobotka, Jindřich (advisor)
The aim of the bachelor thesis is a project documentation for the construction of an apartment building with four aboveground floors and one underground floor. In the aboveground part of the building are 10 accommodation units with generous living spaces. Loggia is included in some of these apartments. The highest floor is designed as a receding one, so there is enough space for terraces. In the underground part are basement cubicles, utility room, room for bicycles, room for strollers, elevator machine room and storage room. Parking is provided outside the building on the paved land. In total there are 17 parking spaces, one for the disabled. The main roof is designed as a flat with a classic layer order with the final layer of TPO foil. The brick building is transverse, built from the Porotherm system, the ceiling structure and staircase are designed monolithic from reinforced concrete. The foundation of the building are CFA piles. There is an elevator in the building. The facade of the buildings is partly contact insulated by ETICS mineral wool system and parts of the facade are ventilated by Prefa mineral wool aluminium sheets.

Controlling of programmable analogue circuit
Sobotka, Josef ; Hanák, Pavel (referee) ; Vrba, Kamil (advisor)
This work deals with the design of the control software for the programmable analog circuit adjustable by means of a computer via the serial interface for the computer, as well as for programming the microcontroller. In addition, analyses the internal structure of programmable analog circuit on which it is proposed to further control, design of printed circuit boards for final programming and test equipment and measurement of the basic parameters of the circuit (transmission and phase frequency characteristics of parts and units).

Current security trends in mobile networks
Jirkovská, Šárka ; Sobotka, Jiří (referee) ; Doležel, Radek (advisor)
This master's thesis deals with the issue of the security of GSM and UMTS mobile communication systems. In the thesis the principles of the authentication and encryption of both the mobile systems are described. Further, the constituent algorithms used for identity verification, key generation and encryption are mentioned. The commonly used algorithms are described along with their weaknesses. In the following part of this thesis, well-known attacks on GSM system are mentioned. In the part where UMTS system is dealt with one can find the algorithms used in this system to increase the security of transmitted data and authentication in comparison with GSM system. Therefore the whole process of authentication and encryption is described separately. In the last part the creation of programming models of authentication and encryption in GSM and encryption in UMTS is described. These models are created in the environment of Matlab version 2009b.
