Signal processing and receiving in UMTS system
Hron, Michal ; Hanus, Stanislav (referee) ; Kejík, Petr (advisor)
This semestral thesis be concerned with datailed analysis of receiving and processing signals in UMTS network system. Insistence of this work is setting to principals of RAKE receiver and processing signals in CDMA networks downlink channel. Through development system MATLAB simulates real function of RAKE receiver. This project is giving fundamental knowledges about receiving and processing of multipath signals to readers.

Creation and processing of signal database
Glett, Jiří ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The work become acquainted with history and rise databases globally. Construes philosophy structuralization, sorting and purpose using. Work further deal with concrete databases softwares intended directly to processing audio signals. Further treat of programmes that the make possible generation personal database structures. Work deal about SUSAS database and analysing its content. It is created self database of music signals, which includes several musical groups always similar in certain aspect. Speech database contains records from the SUSAS database and records from television programs, reality-shows, sports broadcasts, reports and documents, when speakers are subjected to stress and emotions. The work is a database program that can effectively classify all records and processes. The database can be freely extended. The resulting program was realized into Czech and English version.

Electronic Circuits for Biomedical Applications
Pisarenko, Tatiana ; Langerová, Petra (referee) ; Zmrzlá, Petra (advisor)
Tato bakalářská práce obsahuje úvod do biomedicínských signálů a možnosti zpracování těchto signálů elektronickými obvody. Významná část práce se zaměřuje především na popis EMG signálu. Součástí práce jsou take schemata elektrických obvodů, které se používají především pro zpracování EMG signálů. Dále má práce praktickou část, v níž byly v simulátoru OrCAD Capture ověřovány funkce a parametry navrženého obvodu.

Methods of multiple access for terrestrial radio networks
Žák, Josef ; Novotný, Vít (referee) ; Havelka, Dušan (advisor)
The content of this work is focused on the methods of multiple access for terrestrial radio network. These methods are exploited by the systems second and third generation of mobile networks. Specification the basic characteristics these methods is responsible part for inquest the correspondent specificities. Reason is that, that the wireless mobile communication it is possible split by three generation. First is NMT, with analog frequency modulation, which dont make use already, because has considerable disavantages . Analysis second generation mobile systems GSM leads to determination to many advanta- ges hereof system, who be based on methods FDMA, TDMA, CDMA. Description these methods is specialized on their spreading properties. Third generation of mobile systems UMTS is characterized wideband technology WCDMA, making use two duplex methods (FDD, TDD). Both methods provide higher efficiency of recovery frequency spectrum . All the theoretical approaches are examined in the last part of this work.it´s then possible after complete analysis these methods, make a design and a realization. In this event was used the computer programme Matlab–Simulink for simula- tion of duplex method WCDMA-FDD. Evaluation of this technology provides confrontation with second generation GSM .

Optical Method to Evaluate the Contractile Function of Isolated Cardiac Myocytes
Kopečný, Josef ; Harabiš, Vratislav (referee) ; Čmiel, Vratislav (advisor)
In this master´s thesis we will firstly focused on the description of a cyte in terms of structure as well as in terms of electrical and chemical processes. We will examine a processes, which make a contraction and the processes on cyte membrane. We will also analyse image processing methods and methods for measuring the contraction. The block diagram will be designed and requirements for the measuring platform will be specified. The programme will be realized in LabWIEV programming language.

Unconventional methods of processing materials for knives
Bražina, Jakub ; Němec, Karel (referee) ; Doležal, Pavel (advisor)
This thesis focuses on the issue of unconvetional cutlery materials, their application for production, and the processing of a hunting knife. The readers are aquainted with cutlery issues in the search section, where the basic characteristics and properities are written. The next part describes the various metallic and non-metallic materials and their possible properities of processing and production. This thesis also deals with the surface protection of these cutlery materials. The second main part describes construction design, material selection, heat treatment, and with surface treatment of the hunting knife.

Network traffic processing at very high speed
Cabal, Jakub ; Dvořák, Vojtěch (referee) ; Fujcik, Lukáš (advisor)
Different network devices require processing of the network traffic. To process the network traffic, it is necessary to parse headers of particular protocols packed in incoming ethernet frames. The processed headers can be repackaged to ethernet frames and sent back to the network. The goal of this thesis is to design and implement a circuit for analysis and parsing of ethernet frames, together with circuit for deparsing ethernet frames. The circuits are designed for throughputs of up to 400 Gb/s. The circuits are implemented for the FPGA technology.

Energy use of biomass
Zátopek, Zdeněk ; Šnajdárek, Ladislav (referee) ; Baláš, Marek (advisor)
The main goal of this thesis is the assessment of possible use of biomass for producing heat energy. For solving this task is necessary to make research about individual types of biomass suitable for processing. In next it must be done a research about technologies used for producing heat energy from biomass. These information have to aim at creation of overview of industrial apllications of those technologies.
