Energy Harvesting Power Supply for MEMS Applications
Smilek, Jan ; Leuchter, Jan (oponent) ; Ondrůšek, Čestmír (oponent) ; Hadaš, Zdeněk (vedoucí práce)
This thesis deals with the development of an independent power source for modern low-power electronic applications. Since the traditional approach of powering small applications by means of primary or secondary batteries lowers the user comfort of using such a device due to the necessary periodical maintenance, the novel power source is using the energy harvesting approach. This approach means that the energy is scavenged from the ambience of the powered application and converted into electricity in order to satisfy the power requirements of the newest MEMS electrical devices. The target applications for the new energy harvesting device are seen in wearable and biomedical electronic devices. That places challenging requirements on the energy harvester, as it has to harvest sufficient energy from the ambience of human body, while fulfilling practical size and weight constraints. After the preliminary requirements setting and analyses of possible sources of energy a kinetic energy harvesting principle is selected to be employed. A series of measurements is then conducted to obtain and generalize the kinetic energy levels available in the human body during various activities. A novel design of kinetic energy harvester is then introduced and developed into the form of a functional prototype, on which the actual performance is evaluated. Aside from the actual new harvester design, the thesis introduces an original way of improving the power output of the inertial energy harvesters and provides statistical data and models for the human energy harvesting usability prediction.

Cost Benefit Analysis of Wind Power in Germany
Labunets, Nazariy ; Zajíček, Miroslav (vedoucí práce) ; Benčík, Daniel (oponent)
The objective of this thesis is to perform a cost benefits analysis of the wind power sector in Germany, with the horizon of 2030. Various costs and benefits stemming from the expansion of wind power are inferred from literature review and studying the peculiarities of the German case. The magnitude of governmental support is calculated by applying the Weibull distribution of wind at different zones across Germany and power curves of 5 modern wind turbines, as specified by the law. A number of sensitivity analyses is performed on the main inputs for onshore installations. Under the baseline assumptions, the onshore sector is found as non-beneficial to the society, without a visible improving trend for the future. While the offshore sector does not reach a point where the benefits would start overweighing the cost until 2030, the overall trend look much more promising. Powered by TCPDF (www.tcpdf.org)
