Software support for cryptography system training based on discrete logarithm
Kříž, Jiří ; Zeman, Václav (referee) ; Burda, Karel (advisor)
Current needs of human communication came to status, when most of transferred messages are considered as private and transition over non-secured communication lines in open form is not possible. That originated a lot of different methods for securing of messages and transfers in ciphered form. Two mainstreams were established, symmetric cryptography and asymmetric cryptography. Second of mentioned groups is based on usage of two information – keys, when one of then is broadly known and is public and second, well protected and private. Using a public key it is possible to establish a cryptogram of message, but for deciphering it is necessary to know private key. Asymmetric methods are based on mathematical problems, for which there is not an effective computing algorithm. This thesis are focused for asymmetric cryptosystems based on discrete logarithm problem, where ciphering of message using public key is very easy and quick, but deciphering without knowledge of private key is extremely time consuming process. Work describes a mathematical base of discrete logarithm problem, its’ properties and methods developed for solving of this problem. Descriptions of particular cryptosystems are given, i.e. ElGamal cryptosystem, Diffie-Hellman protocol and DSA. Second part of thesis is focused for web application developed as study support of discrete logarithm problem and of cryptosystems using this problem. It describes functional and graphical interface, work with it and options given to user working with application. Mentions also lessons for user which should help with understanding of described problems and practicing.

Technological stage of the kindergarten building gross supersturcture in Slavkov u Brna
Kříž, Jiří ; Štěrba, Martin (referee) ; Motyčka, Vít (advisor)
The bachelor thesis deals with several parts of the technological stage of the gross superstructure realisation. The thesis primarily focuses on the technological implementation of the roof deck. Several other topics are also covered, namely the design concept of the building site, construction machinery and the technological process schedule. The roof deck is designed as a single-roof construction consisting of three differently composed parts. The material list, broken down to each phase of the work schedule, is included as a part of the technological prescription. Furthermore, the thesis proposes a roof drainage solution based on a concept of catchments wedges. Additionally, detailed sequences of operations for each of the work phases along with detailed solutions of the vegetative roof and waterproofing also are integral parts of the thesis.

Sound in feature films without speech
Klusák, Martin ; ČENĚK, Jan (advisor) ; KŘÍŽ, Jiří (referee)
The main goal of this thesis is to describe the unofficial genre of films without speech and to analyze principles of the use of sound and film language in such films.
Initial chapters speak generally about the phenomenon of feature nonverbal cinema with the focus on its historical development and general film language.
The middle part presents, and briefly describes chosen films without speech, and suggests their sorting into sub-genres.
The last, vastest part of the work, is an analytic study of various approaches to reduce speech generally throughout film. This part leads into the final theoretical description of soundtrack in films without speech.

Sound Dramaturgy in Films of Alfred Hitchcock
Patríková, Michaela ; Bláha, Ivo (advisor) ; Kříž, Jiří (referee)
The thesis deals with sound in the work of director Hitchcock. The first part is concerned with A.H.´s relationship towards sound film. It focuses on his film style, his opinion on the birth of sound film and his approach to working with sound. The aim of the second part of the thesis is to analyze sound dramaturgy in selected nine films of Hitchcock. The analysis is accompanied by a DVD with clips of crucial scenes.

Evolution of Sound Making in Czech Cinematography
Pavlovská, Kateřina ; Němec, Daniel (advisor) ; Kříž, Jiří (referee)
This dissertation describes the recording and postproduction of audiovisual pictures´ sound track in the territory of today´s Czech republic between the years 1930 and 2005. Above all, it reports its technological and methodological progress. Barrandov film studio is in the focus, having provided film pruduction of czech films for more than 30 years. Soundtracks for the first talking pictures were made on the 35mm film negativ. 20 years later the analogue magnetical recording of sound came to use and stayed as the main technology for about 35 years. After the analogue period the possibility of digital sound recording appeared. The dissertation analyses the specifics of each era and shows short samples from various czech films on the attached DVDs. The dissertation compares the situation of technological equipment and production processes in the particular periods with the general technological progress. Also the economical and political fatcors/elements are important in the overall history, because they influence the production of the films in a very specific way.
