Principles of Creation and Set of Demo Applications Running over AndroidOS
Sztefek, Lukáš ; Bidlo, Michal (referee) ; Strnadel, Josef (advisor)
The aim of this thesis is to describe the basic principles of creating applications for Android operating system. The reader gradually gets familiar with the basic building elements of applications, including the creation of a graphical user interface. A great emphasis is placed on the description of sensors interface, which precedes chapter describing implementation of several applications. These applications use sensors for their activity. This thesis gives a basic understanding of developing applications for Android OS.

Development of a sensing platform for the study of physiological functions of living cells
Marková, Aneta ; Víteček, Jan (referee) ; Vala, Martin (advisor)
The aim was to develop a sensing platform on the base of organic electrochemical transistor (OECT). The focus was on the preparation of proper electrode system and on optimalization of properties of thin layer of organic semiconductor. As a base, commercial glass substrates with integrated indium-tin oxide electrodes were chosen. Thin layers were prepared from organic semiconductor poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) by spin-coating. Four formulations of material were studied. Layers with different thickness were prepared and the dependence of transconductance on the thickness of the layer and ratio of width and length was observed. The degradation of electrode system was solved by galvanic plating with gold. Attention was also paid to modifications to PEDOT: PSS. It has been found that the optimal layer thickness for use in sensors is approximately 150 nm. By reducing the series resistance by using a silver paste, the transconductance of 23 mS was obtained for the Ink 2, for the Ink 3 the transconductance was 44 mS. Sensoric platforms with these transconductances can be used for detection of physiological functions of electrogenic cells, e.g. cardiomyocytes.

Wireless sensor network
Šťáva, Radek ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The main theme of this work is to design and make a modern network of wireless sensors, when the main used circuit in the sensor module and the receiver module is microcontroller Texas Instruments CC430F513x. Care is taken primarily at very low power of sensor module for long battery life when on battery power. It is also emphasis is on reliability involvement of miniature size, expandability and high precision modules of basic sensors.

Light Airplane Flight Parameters Estimation
Dittrich, Petr ; Pačes, Pavel (referee) ; Fiľakovský, Karol (referee) ; Chudý, Peter (advisor)
Tato práce je zaměřena na odhad letových parametrů malého letounu, konkrétně letounu Evektor SportStar RTC. Pro odhad letových parametrů jsou použity metody "Equation Error Method", "Output Error Method" a metody rekurzivních nejmenších čtverců. Práce je zaměřena na zkoumání charakteristik aerodynamických parametrů podélného pohybu a ověření, zda takto odhadnuté letové parametry odpovídají naměřeným datům a tudíž vytvářejí předpoklad pro realizaci dostatečně přesného modelu letadla. Odhadnuté letové parametry jsou dále porovnávány s a-priorními hodnotami získanými s využitím programů Tornado, AVL a softwarovéverze sbírky Datcom. Rozdíly mezi a-priorními hodnotami a odhadnutými letovými paramatery jsou porovnány s korekcemi publikovanými pro subsonické letové podmínky modelu letounu F-18 Hornet.

Robot Controlled by PIC Microprocessor Unit
Heřman, Petr ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design of a cheap robot. It includes implementation of firmware of low level control unit based on microcontroller PIC. The firmware drives motors, gains sensors data and communicates with the high level control unit. Furthermore the thesis presents realisation of connection to the robotic operation system ROS and its standard structures allowing usage of existing packages for the robot teleoperation and displaying sensor data on the remote computer. The thesis finally reports experiments with the robot. The constructed prototype is the model of the robotic lawn mower, however the whole solution has universal usage.

Wireless meteostation
Marčišovský, Peter ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
This bachelor thesis deals with design of weather station, which is able to measure temperature, humidity, barometric pressure, direction and speed of wind and intensity of solar radiation. Whole device is divided into two parts. The sensor part situated in exterior and display part situated in interior. Wireless communication is used to communicate between this two parts. Measured data are displayed on display situated in interior in regular intervals. In addition, measured data are displayed in GUI application and stored to file, after connecting weather station to PC using Bluetooth module.
