Spectral method for motor parameters identification
Sedláček, Filip ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This project deals with the problem of spectral method for system identification. Introductory part acquaints reader with basic concept of identification and explains its application in practice. It describes and mathematically derives two non-parametric methods for identification – correlation method and spectral analysis. The main aim of this final project is testing and implementation of spectral analysis in system parameters identification, which is specifically described in remaining sections of this project. These sections discuss a fundamental rules, procedures and principles in order to prepare a reader as much as possible for its final application in REAL-TIME system identification.

Measurement of wind oscilatory waves on reservoir
Kotaška, Stanislav ; Pelikán,, Petr (referee) ; Špano, Miroslav (advisor)
This diploma thesis deals with the measurement of wind oscillation waves on reservoirs, especially with regard to the determination of wave properties with a focus on the spectral density. The thesis presents the basics of the theory of creation and propagation of wind oscillation waves, the recherche of measuring devices and a description of the pilot measurement with the processing of measured data in the MATLAB environment using the software tool WAFO. Attached to the CD are sample scripts for data processing from the resistance sensor.

Spectral impuls signal analyzis
Měcháček, Radek ; Kubásek, Radek (referee) ; Fiala, Pavel (advisor)
Analysis signals, especially then pulsed signals and their next processing, today alreadyquaere to many different technological line. From communication engineering over telecommunication and acoustics, after as much as field - club application or multimedia. This work is introduction to the problems methods processing pulsed signals. Is distributive how from the standpoint of theory, so from look future application usage, by the help of programmatic analyses basic signals. Work bears basic description, notions, routes and method for work and analysis with widthspectral and ultraswidthspectral signals. Further be created tool for generation, filtration and near processing of several basic pseudo - random signals.

Hydrological Time Series Analysis for Chosen Sub Catchment in Morava River Basin
Černý, Vojtěch ; Benáčková, Kateřina (referee) ; Marton, Daniel (advisor)
Current climate conditions raise questions about how climate change should affect the hydrological regime of the Czech Republic. The main questions are: I) Is climate change serious and is it already tangible in hydrological series? II) Are there significant changes in the climatic conditions, or in the flow of the river network? III) How does climate change affect hydrological conditions in the catchment? IV) Are there non-stationary tendencies in the hydrological series caused by climate change? The aim of this work was to perform a basic analysis of hydrological time series and estimated its possible changes. The analysis was done with using autocorrelation function, spectral density, moving averages methods, statistical characteristics, empirical line of probability of exceeding and last but not least by decomposing the time series. The practical application was applied on time series of average monthly flows determined in the hydrometric profile of Dalečín in the Svratka river basin.

Water Management Analysis of Storage Capacity of the Vranov Reservoir
Vítková, Lucie ; Havlík, Martin (referee) ; Marton, Daniel (advisor)
The current persistent drought and changes in the climate system have raised water managers expert questions about how to manage water resources in the future. The manifestation of climate change in hydrological series and their influence on the magnitude of threats to the storage functions of reservoirs are more often investigated. Already today, long-term shortages of storage capacity in reservoirs lead to the introduction of special manipulations on water structures. The aim of the thesis is to perform the analysis of time series, respectively decomposition of hydrological series average annual and monthly discharges. Create extended hydrological bases using synthetic discharge series generators and develop a comprehensive analysis of storage volume without considering losses even with the introduction of losses from the water surface vapor in the UNCE RESERVOIR program. The created discharge series are compared and evaluated on the basis of statistical characteristics and reservoir storages results with the real discharge series. The practical app is conducted on the Vranov reservoir in the Dyje River Basin.
