Study of Energy Harvesting in Aeronautic Applications
Březina, Martin ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
Motivation of this study was to clarify the possible solutions to reduce the number of general aircraft security controls with keeping the required safety of flight operations. Among the appropriate approach to solving the problem seems to be the use of energy harvesting devices to power wireless monitoring system of aircraft structures during their operation. The work deals with the various alternatives of using the ambient energy available in the general air transport and processing methods. The study also includes the selection of a particular type of processing available ambient energy and determination of parameters of selected energy-harvesting generator using simulation modeling and performance to meet the power requirements of monitoring system sensors.

Equivalent electromechanical circuits for modelling of dynamic systems
Legerský, František Jozef ; Rubeš, Ondřej (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with solving and modelling of dynamical systems using electromechanical analogy. A review of the use of electromechanical analogy of systems is made. Then a mechanical model of a piezoelectric beam is described by using differential equations and subsequently an equivalent circuit is made by using a voltage analogy, in which the power is simulated. A mechanical model and its equivalent circuit are made for the electromagnetic vibration generator using current analogy. The last part of the work is the modelling of complex piezoelectric and electromagnetic models and the influence of body weights on the vibrations.

Production of electricity from the vibration of the bicycle
Novák, Pavel ; Sobotka, Jiří (referee) ; Koutný, Martin (advisor)
The work is focused on methods of obtaining energy from the environment. In the project, there are summarized and generally described some methods of energy conversion. A more detailed description is aimed at a method on the principal of the Faraday's effect. The work involves a calculation of the electromagnetic generator with specific parameters, a simulation of the calculated generator and builds a real product on the basis of the previous theoretical calculation. The aim is to create a product that accumulates the energy obtained in the attached battery.

Electromagnetic energy harvesting resonator for train trackside
Rusková, Miroslava ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
The aim of the diploma thesis was to design an electromagnetic generator to the purpose of supplying signalling and safety devices on the rail tracks. The electromagnetic generator is a separate electrical source, which is mainly needed for safety in the case of not covered tracks by electrical installation. The thesis proposes two types of electromagnetic generator and one with non-linear stiffness, which are designed for the passage of trains with low frequency.
