Incubator with adjustable temperature and humidity
Hikaník, Matúš ; Král, Bohumil (referee) ; Steinbauer, Miloslav (advisor)
This project deals with comparing types and properties of commercial produced incubators for exotic birds. It searches the best solution from these area. In this project are compars individual components and their choice for realization in this project. Then in this project is solution of regulation temperature and humidity in engineered mechanism and discovered parameters of specifically space. Then is developed solution of thermostat and hydrosatat for this prototype. Temperature is changed by Peltier module, who is involved in correct system. Humidity is regulated by resistor humidifier. Complex system is managed by microcontroler. System communicates with PC via USB interface and Ethernet. Solution of this project is maked functional prototyp.

Wireless transfer of energy
Varga, David ; Koňas, Petr (referee) ; Steinbauer, Miloslav (advisor)
ork tie together on first project, in which the was designed apparatus for tests wireless transmission energy. Antenna was synthesized and theoretically optimized for experimental operation, in which the will performed series measuring. In first part is practical description of realization proposal. It consists of circuital solution, proposal measuring workplace and mechanical construction with illustration photographs of arrangement. Second part includes results of performed measuring. These measuring will divided by three basic groups: in first group will by testing feature one’s antennae, in second group will series transmission measuring power gain, and in third group will photographed shape of field, and comparison with simple simulation finite difference method. Third part summarises results from measuring, and prepares consecutive balancing visualisation project, which is of thematic bent on chosen aspects theoretical hypothesis and effected experiments.

Thermal conductive plate with controlled thermal field
Masár, Pavol ; Král, Bohumil (referee) ; Steinbauer, Miloslav (advisor)
This work deals with design of thermal source of panel shape for scientific biological application. Panel has adjustable surface temperature and thermal gradient. The first part of this work concern with design and numerical modeling of the thermal system, application of materials and arrangement of thermal and cooling devices – Peltier elements. Second part of this work is about construction of the panel and experimental measurement.

Programmable Thermoregulator Design
Kollár, Tomáš ; Steinbauer, Miloslav (referee) ; Hermany, Jiří (advisor)
The aim of the study was to design, build and experimentally verify a programmable thermostat. The main control unit of the thermostat is an ATmega168 microcontroller which communicates via I2C bus with remote MAX6615 chips. They are used to measure temperature with a set of thermistors and control the flow of the hot water in the heating system. This work deals with issues of remote control through the I2C bus, servomotor steering, precision temperature measurement and describes the inner workings of the system. The next chapter includes a proposal for possible extension of the system. The last part contains the manual of the control menu structure and a brief description of the software.

Meterology of air ions
Škvor, Martin ; Steinbauer, Miloslav (referee) ; Bartušek, Karel (advisor)
This thesis is focus on measuring of air ions concentration, which produce home ionizers. Aspiration condenser has been used for it, because it is able to measure small currents in the order to pA. Spectrum charakteristic has been employed for comparison of measurement results and has been obtained by grafic method from measured saturation charakteristic. Subjects, which the most affect accuracy of measurment air ions concentration and also having impact of air ions concentration at all, are the result of my thesis.

Ion fields measurement
Svozil, Radek ; Szabó, Zoltán (referee) ; Steinbauer, Miloslav (advisor)
The aim of this semester project is the introduction to the problematic of ion fields, where and under what circumstances they originate and extinct and the techniques of measurement. The project will deal with the atmosphere and the electrical field of the Earth. I will consider the composition of the atmosphere and the principles of origin and extinction of ions. I am going to mention the division of ions and their influence on the living organisms. Another topic to be dealt with is the methods for measuring the air ions and the small currents. Gradually we are going to learn the known methods of the measuring of air ions. We are going to get a closer look at the method of measuring with the cylindrical aspiration capacitor. We are also going to deal with the problem of measuring very low currents, where they originate and how it is possible to compensate them. The outcome of the project should be the concept and later the creation of the sonde for the measuring of the ion fields itself.

Impact of conductive material on RF magnetic field deformation
Vondra, Petr ; Steinbauer, Miloslav (referee) ; Dědková, Jarmila (advisor)
The work analyses formation of deformations of RF magnetic field within the environment of electrically and magnetically conductive materials. An analytic solution of the problem is created and the problems of numerical modeling are solved. In theoretical way, the work also familiarize with the use of magnetic resonance imaging method - the spin echo method (SE), with its features and possibilities of its use within the aim of the project. This method is used for experimental measurements of electrically conductive materials in the NMR laboratory in ISI AV Czech Republic. Results of the simulation are compared with results of the experimental measurement.

Low-level measurement methods
Müller, Tomáš ; Steinbauer, Miloslav (referee) ; Fiala, Pavel (advisor)
This bachelor thesis discuss about low-level measurement methods. Also is outline the method, how to proceed in lay-out of measurement system and in selection of measurement device and its accessories. Thereinafter is stated the calculation of mistakes and in recent time also the calculation of often use mazes. Without them would be not the result total. Next part of this bachelor theses pointed to practical measurement in the area of low level current and voltage, where are shown and described wiring types used for these measurements. Next chapters discuss about measurement principles low level electric current and voltage. Than try to point to appearance, which indisposed participace on measurement accuracy and try to introduce with steps, which helps to reduce this effects. These voltages and currenties are in normal measurement insignificant, but in the low-levels influence they the result too much. Thereinafter is described the principle of measuring amplifier and closer mentioned parameters and usage of instrumentation amplifier with ultra low input bias current INA 116. Next to last point of this bachelor thesis is an example of usage this network in measurement with gerdien condenser. Therein is clarify its physical principle and proposal parameters. In the last part is described the air ions concentration measurement with gerdien condenser. Also are described the results of measurement and results of this.
