Renewal of the baroque rectory in Sebranice
Bubeníková, Zuzana ; Muroň, Ivo (referee) ; Ležatka, Lukáš (advisor) ; Sobotka, Jindřich (advisor)
This bachelor's thesis is aimed at the preparation of documentation for building permits and construction, based on previous architectural study for renewal of the baroque rectory in Sebranice. The projects is focused on the application of suitable methods of the reconstruction of a cultural monument along with the proposal of a new functional utilisation of the surrounding site. The design itself is characteristic by its careful and sensitive approach towards the listed building. However, it also pursues the present methods of site creation and adds a contrasting new structure to the environment, aiming to accommodate the modern standards of comfortable utilisation. The synthetic approach of the design is prominent in the effort to recover fragments of the original state of the building, as well as using present materials and colour schemes. The final outcome of the design respects the past of the landmark, adapts it to modern requirements and prepares it for its promising future.

Meatpacking plant
Majtán, Marián ; Procházka, Martin (referee) ; Sobotka, Jindřich (advisor)
The diploma thesis is focused on project documentation of Meat packing plant. Along with meat processing the documentation solve question of accomodation for employees. Building consists of two main sections: The processing – it is structured under requierements of meat packing industry. Second one is residential part set in 2nd, 3rd and 4th floor. Main inspiration for design are meat packing plants in Scandinavian countries, where is often need to provide accomodation to employess because of disadvantageous geographic locality. Building is built of Heluz building system, perimeter walls consists of insulation filled blocks. Building is without basement and it is based on footings of plaint. The roof is flat, partially designed as extensive green roof. Isover system is used to thermal insulation. A part of object is also asphalted plain for transport goods to and from the meat packing plant.

Disposal of Biotic Pests by EMW Radiation
Sobotka, Jindřich ; Klečka,, Tomáš (referee) ; Myslín, Jiří (referee) ; Tomíček,, Oldřich (referee) ; Šuhajda, Karel (advisor)
The possibility of using high-frequency electromagnetic radiation in the construction sector is a common knowledge. Various experiments have been carried out to dry construction materials, or even to destroy biotic pests. However, the majority of these experiments have been executed in laboratory conditions. It means they have been carried out under exact limiting conditions, often very far off those conditions in real building practice. Therefore, this dissertation aims at exploring the possibility of utilizing microwave technology in drying and heating of construction materials, in disposing of biotic pests and sterilizing building materials under real conditions in building practice. The thesis will explain that microwaves are a term given to a part of electromagnetic radiation. Electromagnetic radiation is based on the principle that the radiated energy is absorbed by water molecules present in moist building material. In the mass of the irradiated material, the radiated energy is transformed into thermal energy, where a so-called “motion” of water molecules occurs with the energy then being transformed into kinetic energy. The microwave technology itself offers a very wide range of use, which can be easily achieved, thus making the technology available to use in the future. Part of the experiments and the necessary measurements, too, has been carried out on selected types of building materials in the premises of the Faculty of Civil Engineering of Brno University of Technology. They have been executed under conditions which most closely correspond to the conditions in real buildings. Part of the experiments and the necessary measurements were carried out on particular constructions, by the so-called in situ method. As stated in the conclusion of the dissertation, laboratory measurements and the in situ measurements differ considerably in some cases.

Production buildings VW Autocenter
Macholánová, Petra ; Vranová, Daniela (referee) ; Boleslavská, Yvona (advisor) ; Sobotka, Jindřich (advisor)
This Bachelor thesis deals with a new building of Carcenter VW Group located in Brno city, north-east ftom the inner city, in a city part Zábrdovice, on Cejl Street. The building site is recognized in cadastral list by the Brno City Council as Brownfield with the number 3402. It has a iregular shape with area of 1.15 hectares and it is oriented to the north-south direction. From the east it is bordered by a protective belt of the river Svitava. From the south is the site bordered by the Cejl street and from the western side is bordered by the Jana Svobody street. The land is located in an industrial zone, surrounding buildings are of mixed use. The building of carcenter is situated perpendicular to the southern boundary. The access into the area of the building is designed from the road on Cejl Street. Urban solution allows independent use of a showroom and a service warehouse. There are designated separate parking areas for the needs of individual operations of both parts. The building is designed to meet the requirements of the service carcenter VW Group. It will serve as a showcase and a selling point of cars of Volkswagen, Škoda, Audi and Seatvas well as a service and spare parts stock shop.

Network attacks by Cain & Abel
Smékal, Lukáš ; Stančík, Peter (referee) ; Sobotka, Jiří (advisor)
This Master’s thesis is dealt in the local area network security, cryptographic algorithms, particular attacks on computer networks a practical application these attacks in local area networks. To application particular attacks is used the Cain & Abel program. The detailed manual for this program is created from the results of these attacks. This manual contains the exhibits of usage particular program tools and the attack application exhibits. This manual considers consequences of particular attacks and summarises achieved results during work with tools too. Master thesis closely deals with one of the program tools called RSA SecureID Token Calculator. Authentication via hardware tokens is contained in this Master thesis. Thesis contains the way of authentication using RSA SecureID Token Calculator without physical owning of the hardware token. Cain & Abel program shows and interprets why cashed passwords in operation system are dangerous and it shows methods how attacker can reveal this passwords from the operation system memory. This Master thesis is focused on sniffing credentials and passwords in local area networks and it is focused on cryptographic algorithms cracking for username and passwords revealing.

Modern Asymmetric Cryptosystems
Walek, Vladislav ; Sobotka, Jiří (referee) ; Malina, Lukáš (advisor)
Asymmetric cryptography uses two keys for encryption public key and for decryption private key. The asymmetric cryptosystems include RSA, ElGamal, Elliptic Curves and others. Generally, asymmetric cryptography is mainly used for secure short messages and transmission encryption key for symmetric cryptography. The thesis deals with these systems and implements selected systems (RSA, ElGamal, McEliece, elliptic curves and NTRU) into the application. The application can test the features of chosen cryptosystems. These systems and their performance are compared and evaluated with the measured values. These results can predict the future usage of these systems in modern informatics systems.
