Apodization of the fibre Bragg gratings by use of phase mask UV exposition
Burian, Tomáš ; Hejátková, Edita (referee) ; Urban, František (advisor)
This thesis describes the problem of fiber gratings, focusing primarily on the use of Bragg's grids in the sensor. It describes the types of fiber mesh production, especially the method of writing with a phase mask. The next part deals with the possibilities of using apodization in fiber optic systems. It deals with the various functions that can be used to describe apodization. The following part describes the moire principle, especially the method of overlapping two phase masks with a different period.

Agent-Based Monitoring of Wireless Sensor Networks
Houšť, Marek ; Kočí, Radek (referee) ; Zbořil, František (advisor)
The reader is first introduced with history and possible applications for wireless sensor networks. The thesis then describes the problems of wireless sensor networks and implementation tools for wireless sensor networks. The thesis also presents the system WSageNt and its client web interface. Practical part is based on the design of agent elements. Describes gradual implementation, testing and practical realization of these agent elements in the system WSageNt. The final part discusses the advantages and disadvantages of the project and identifies possible future expansion of the system.

Control unit of four - legged robot based on microcontroller PIC
Youssef, Daniel ; Lamberský, Vojtěch (referee) ; Grepl, Robert (advisor)
This Bachelor thesis develops “Jaromir“, a four legged robot by adding appropriate sensors to it and designing a new control unit that is able to receive and process the acquired data by the sensors. The functionality of the control unit is tested by implementing a number of simple movements. This testing demonstrates the possibility of using this unit for the developing and testing of complex movement algorithms.

Evaluation of pressure conditions in the quenching chamber of low-voltage device
Nevrzal, Filip ; Vávra, Daniel (referee) ; Valenta, Jiří (advisor)
In this master’s thesis there is firstly conducted research about pressure measurement. Next there is mathematical description of thermodynamic conditions in used testing chamber by using magnetohydrodynamic and Maxwell equations. Next chapter deals with testing chamber itself, more precisely with function, model and changes done to it. In practical part there are data measured by used sensors, which are also closer described in this chapter. In next chapter there is comparison of reaction times of used sensors and their frequency specters, obtaining using fast Fourier transformation. Second to last chapter introduces very measurement on the real device and in the last chapter these data are analyzed and more closely described.

Platform for Mobile Agents in Wireless Sensor Networks
Horáček, Jan ; Kočí, Radek (referee) ; Zbořil, František (advisor)
This work deals with implementation of an agent platform, which is able to run agent code in wireless sensor networks. Implementation has been done for MICAz platform, which uses TinyOS operating system for developing applications. This work contains list of chosen TinyOS parts and illustrates, how such a platform can be used for our purposes. We will describe main features of ALLL language and we will also demonstrate some examples of agents.

Structures in optical fiber
Polreich, Štěpán ; Čučka, Milan (referee) ; Urban, František (advisor)
This thesis describes the basic concepts, principles and basic characteristics od optical fibers. There are some particular types of structures of optical fibers and their use in practice. The work is also presented technology of these structures. For each of the structures is also described in which field are used, if is area of sensor technology or telecommunication technology. Considerable part is dedicated to special structures that are used especially in sensor technology thanks to its high sensitivity. The thesis describes the design of structures which have been machined by using a femtosecond laser and then states in which area thus treated fibers are used.

Local Navigation for Outdoor Robot
Skácel, Martin ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
This diploma thesis deals with complete designing and implementation of local navigation of a robot which travels according to set GPS. This work contains a study of contemporary used principles of the sensors which can be used as the components of the robot. There are sensors for measuring the surroundings of the robot and orientation of the robot in the environs. The equipment includes an instructing control unit with the ATmega8 microcontroller. This equipment collects data from the sensors and transfers them to the other systems of the robot. The following part of the thesis deals with the draft of the buses and communication protocols, which are necessary for connection between the sensors and the control unit. The I2C and RS232 buses were chosen as the most suitable. The communication protocol was borrowed from the semester project written by Bc. Michal Sitta. The main task of this control unit is reading out the data which have been measured from connected sensors. The realization of interface between the sensor bus and the major system is another core goal of the control unit. The system for a local navigation is designed with the approach which allows the widest range of extensibility. During the designing of the control unit the future possibility of insertion other sensors was taken into consideration.
