From Brief to Solution - Commercial Communication in Sociological Perspective
Novák, Michal ; Tuček, Milan (advisor) ; Hendl, Jan (referee)
The aim of the diploma thesis is to describe the issue of transfer of information in commercial communication and advertising. Using the essential sociological theories it tries to describe the process of designing meaningful and successful commercial communication and points out all the complications which can appear. The increased emphasis is put on the importance of understanding the participant's (sender, receiver) behavior and motivations - in commercial communication represented by the knowledge of target group and the brand itself. Based on the theoretical approaches to the communication process - mainly Stuart's Hall reception theory, Cacioppo's Elaboration Likelihood model and Petty's Laswell formula - the thesis describes how to design the advertising campaign properly. It is always helpful to analyze the current situation you are in, analyze your customer's interests and when you finally decide which message you want to use in communication, the keystone of the successful transmission is to code it correctly. You also have to take into consideration the definition of target group, market analysis, media-mix etc., as condition of proper encoding/decoding, minimizing external interferences, therefore maximize effectiveness of message transferring - achieve preferable reading.

Demonstration of Cryptographic Problems through an Interactive Educational Game
Fišarová, Anežka ; Mezina, Anzhelika (referee) ; Mikulec, Marek (advisor)
The bachelor thesis is focused on the design and implementation of a cryptographic interactive educational game. It focuses on various cryptographic ciphers specifically selected so that people outside the field can be introduced to the subject in a demonstrative and entertaining way. Java and JavaFX were used as the programming language. The thesis consists of four parts, the first two are oriented towards the theoretical part of cryptography and the second two are more focused on the practical application and code development. As motivation for the players, a score for correctly cracked ciphers was used. Furthermore, the work includes a choice of difficulty, which influences which ciphers will be presented to the players. At the end of the thesis, the author reflects on the results and explores ways to further improve the methods presented.

Remote wireless control with encoded transmission
Polách, Matěj ; Hanák, Pavel (referee) ; Szabó, Zoltán (advisor)
This thesis deals with a wireless transmissions issues. It describes the device designing which communicate bidirectionally in free frequency band of 2.4 GHz. It deals with the modulation methods, coding and other wireless transmissions necessities and about prefabricated RF modules properties. It solves voltage level shifting which is essential for SPI communication between microcontroler and module.

Memory Reduction of Stateful Network Traffic Processing
Hlaváček, Martin ; Puš, Viktor (referee) ; Kořenek, Jan (advisor)
This master thesis deals with the problems of memory reduction in the stateful network traffic processing. Its goal is to explore new possibilities of memory reduction during network processing. As an introduction this thesis provides motivation and reasons for need to search new method for the memory reduction. In the following part there are theoretical analyses of NetFlow technology and two basic methods which can in principle reduce memory demands of stateful processing. Later on, there is described the design and implementation of solution which contains the application of these two methods to NetFlow architecture. The final part of this work summarizes the main properties of this solution during interaction with real data.

LPC Speech Coding
Zapletal, Ondřej ; Kyselý, František (referee) ; Rajmic, Pavel (advisor)
The contents of the thesis "LPC speech coding" are studies of this method of a parametric source coding, explanation of mathematical procedures that are used in it (linear prediction, autocorrelation, Levinson-Durbin algorithm, transfer to a form suitable for transmission, Chebyshev root searching polynomial method) and acquaintance with the signification and application of that method in real speech encoders. The task of the original project of this thesis is a description and simulation of a simple speech encoder based on LPC, which transforms a real speech signal into a bit flow, which contains all of the significant parameters for its backward reconstruction (LSF coefficients, pitch period, excitation level, voice detection - AMDF method). One part of this thesis is a discussion about currently used speech encoders.

Smart modul integrated in power plug
Rusz, Martin ; Musil, Petr (referee) ; Mlýnek, Petr (advisor)
The aim of this work is focus on Powerline Communication technology and select a suitable type of broadband integrated circuit for the integration of a broadband communication module into an electrical installation box. In the introduction of this work, the Powerline Communication technology, the principle of communication, individual types of technology, factors influencing the quality of transmission, current possibilities and setting goals necessary for the design of the module are analyzed in detail. The result is a miniaturized functional prototype of a fully integrated broadband PLC modem in a wiring box.

Image codecs based on the wavelet transform
Kiska, Tomáš ; Říha, Kamil (referee) ; Rajmic, Pavel (advisor)
This bachelor´s thesis describes issues of wavelet compression, which is today already in common use mainly at work with digital photographs or other pictures. Using these algorithm you can copy informations and save efficiently. There are main image formats and types of compression suitable for editing pictures desribed in this thesis. So the focus is on discrete wavelet transform, which uses so-called wavelets, the Haar´s and Daubechies wavelet are the best known of all. Next chapter of this work explores colour spaces, in which can be a picture displayed. In case of coding and encoding it is model RGB and YCbCr. Not least there is mentioned term of picture decomposition. At the end, there are image codecs EZW, SPITH and EBCOT which are describe in detail.
