Simulation of solar cells using
Frydrych, Michal ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
This thesis deals with problems of production of an electric energy by the help of photovoltaic panels. There is mentioned an analysis of problems at calculation of solar system for “island” operation of house, description of all partial segments needed for photovoltaic system and analysis of final costs on purchase of this system. A point of this thesis was making a model of house which used the photovoltaic panels for its function. On this created model was made a measuration during a common day at laboratory conditions and determination the important parameters of solar panel.

Measuring the power of IC-engines
Adamec, Vojtěch ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with topic measuring the power and the torque of internal combustion engines on chassis dynamometer. The aim of the thesis was to show advantages and disadvantages of different types of dynamometers, to make review of standards for measuring power on chassis dynamometer, effect of atmospheric conditions, resistances and slippage. Thesis also describes evolution, different designs of chassis dynamometers, effect of roller diameter to rolling resistance and deformation of tire, suitable types of dynamometers for chassis dynamometer, equipment of testing room, modes of operating and differences between static and dynamic power testing. In the end I have made prediction of incoming development devices of this type with regard to evolution of intelligent chassis control systems and electric vehicles.

Microbial biomass phosphorus measured by extraction-fumigation method
ČAPEK, Petr
The aim of this study was to assess posible sources of unacuracy in measurement of soil microbial phosphorus by extraction-fumigation method. The biggest one is the correction for sorption in two forest soils of watershed Plešné lake and Čertovo lake and one waterlodged soil. We also tried to assess the correction factor (Kp) for these soils, but we were unsuccesful. We would like to assess extractability of phosphorus sorbed during fumigation and assess Kp factor in future. Therefore we set up an appropriate methodology.
