Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

Stability and autopilot system for airplane RC model
Čamaj, Peter ; Republic), (SAAB Technologies Czech (referee) ; Šebesta, Jiří (advisor)
The master thesis deals with design and realization of stabilizing and autopilot system, which is used in radio controlled model planes. The thesis contains a proposal of hardware platform, which is able to control the plane model based on data measured from a sensor system. Moreover, this thesis describes a software implementation of individual modules, which is measured the onboard values. The basic principles of stabilization and autonomous flight control are also summarized. In conclusion, the system is subjected to flight tests.

Measurement of velocity and frequency in synthetic jet
Flídr, E. ; Šafařík, P. ; Trávníček, Zdeněk ; Broučková, Z.
The aim of this paper is to evaluate resonance frequency of pulsation in synthetic jets of air. Resonance frequency was determined by theoretical calculation. This frequency was compared with experimental results. To obtain frequency characteristics three experimental methods were used. Velocity was measured by Pitot tube and hot wire anemometry in CTA regime. Last method was based on calculation of reaction force from relative weight changes.

Measuring the performance of human capital in the company
PIKHARTOVÁ, Aneta
The main point of my thesis is a complete analysis of the performance of human capital, which can be found in the practical part of the thesis. Synthesis of results and recommendations are summarized in the penultimate chapter. The company innovated the measurement of the performance of its employees in 2010 through the introduction of a new monitoring system Citect SCADA which gives the employee evaluation new dimension, which enabled to increase productivity and reduce labor expenses.
