Localization acoustic near-field sources
Šuránek, David ; Sysel, Petr (referee) ; Míča, Ivan (advisor)
This thesis is focused on acoustic source localization in near field situation. First part of this thesis is dedicated to examining the fundamental issues of acoustic source localization. After that are some of acoustic source localization methods described. Next part is focused on implementation, verification of functionality, comparing of the successfulness and results of the localization. In conclusion are summarized the outcomes of the thesis.

3D shape from camera pair
Bastl, Jiří ; Horák, Karel (referee) ; Richter, Miloslav (advisor)
The aim of this bachelor thesis is to create methods for obtaining 3D data from 2D images. This data will be used as an input data for algorithms which will process them into data formats creating 3D perception. In this work problem of rectification when we compare one image according to the other is solved as well as the problem of calculation of the model of a scene scanned with two cameras.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.

IR thermometer with automatic emissivity correction
Dobesch, Aleš ; Tannenberg, Milan (referee) ; Poliak, Juraj (advisor)
Diploma thesis deals with basic physical quantities and laws relating to non-contact temperature measurement and emissivity determination of solids. It describes the design and implementation of the IR (Infra-Red) thermometer often missed with automatic emissivity correction. The first chapter explains the concept of temperature and basic principles of temperature measuring . The second chapter focuses on the history and theory of non-contact temperature measurement. Gradually are explained the concepts related to non-contact temperature measurement and the problem of determining the emissivity of the body. Next third chapter describes the proposed hardware solution of IR thermometer. The fourth chapter describes a software written for the IR thermometer. The fifth and last chapter summarizes the findings and knowledge from the implementation of non-contact thermometer and measuring emissivity.

Wireless Sensor Network Simulation Model in J-Sim Tool
Vrzal, Tomáš ; Morávek, Patrik (referee) ; Šimek, Milan (advisor)
This thesis deals with the issue of wireless sensor networks and communication protocols. Is explained of what the network is composed, what standards are used and in what sectors are most often used. The main scope of work is to introduce with the localization algorithms using in WSN. Algorithms are clearly divided into groups according to the methods used. In work is describes the structure used simulation tools J-Sim, for creating a wireless sensor network. To create network will be then applied different localization algorithms, which must first be implemented in a simulator using Java code. All generated classes and the algorithms are detailed described in the work. Results from simulations are detailed and graphically displays for individual localization algorithms.

Research of Localization Algorithms in Wireless Sensor Networks
Holešinský, Pavel ; Morávek, Patrik (referee) ; Šimek, Milan (advisor)
This diploma thesis is focused on research of localization algorithms. Each developed localization algorithms are generally application specific. Because of application requirements diversity, many variants of localization algorithms exist. In case of finding appropriate localization algorithm for concrete application usability, existence of real condition simulation environment is useful. Development of this simulation environment was made simultaneously with both localization algorithms. At first, survey of available localization technic was performed and their summary was listed. Further work was aimed on research of two localization algorithms. Both of them use triangulation mechanism to determine unknown node position. This mechanism is based on measurement of distance to three reference points with known position. It would seem that both algorithms are similar, but simulation shows their difference and presents their suitability for diverse conditions.

2D triangulation of heat radiation sources
Zsemle, Radek ; Zuth, Daniel (referee) ; Matoušek, Radomil (advisor)
The aim of this thesis is the creation of intelligent sensor units (Intelligent Sensor Unit ISU) able to identify the source of heat radiation can be distinguished from background. Single System (slave) will communicate via the I2C bus to the central processing unit (Master), which will serve as the setting ISU (slave), so for their own heat source position calculation and communication with staff. The whole system is based on the ISU uP ATmega128. Sensory part will be able to scan the perimeter of the plane 0 ° to 180 °, and distinguished theoretical temperature gradient object-background 2 ° C. A given application can be used for the monitoring of technology and living objects.

The use of the discourse marker 'che' in Rioplatense Spanish: a sociolinguistic approach.
ŠMÍDOVÁ, Markéta
The core of the present master's thesis is a sociolinguistic analysis of the conversational marker 'che' in Rioplatense Spanish. Initially, the history and concept of conversation analysis are presented. The process of grammaticalization and the classification of pragmatic markers are also described. Secondly, the author defines sociolinguistics and, on the basis of William Labov's work, explains methodological problems related to collecting real language data. The terms Rioplatense Spanish and 'porte?o' are widely described as well. Further, 'che' is investigated theoretically as a case of interjection that resulted in a conversational particle. The proper sociolinguistic investigation is based on three methods: introspection, qualitative and quantitative analysis. Functions of 'che', as well as its occurence according to different social factores are studied in this work.
