Marek Brabec, Ph.D. Supervisor's e-mail address: mbrabec@cs.cas.cz Abstract: In the present work there is described the method for estimation of functi- onal data from discrete values and basic methods of functional data analysis. 1

The diploma thesis deals with vibration measurement. The measurement is made by laserinterferometer ML10 GOLD in non – contact way. Different methods and two softwares are used for the measurement. The target of this diploma thesis is to describe these methods, to make the measurement, to analyze the measurement and to compare the results.

The aim of this thesis was to construct an osteobiografical profile of two individuals from the early medieval locality of Kostice-Zadní hrúd, identified, on the basis of grave inventory, as warriors. In order to obtain a clear picture of early medieval warriors and to provide a basis for comparison, we also tried to find out what characterised an average early medieval Great Moravian warrior. Individuals from the early medieval locality Pohansko-Břeclav were chosen as comparative samples of regular population and warriors. The following methods were used to construct an osteobiographical profile: tracking of entheseal changes of muscle attachments, analyses of cross-sectional geometry of long bones and a Fourier analysis of acetabular morphology. We found out that warriors from Pohansko-Břeclav were horse riders trained in close combat, they did not wear heavy armour and did not train with bow. Due to bad preservation, only one of the individuals subject to our study, the individual labelled KZH H003, could be analysed. The man was short in stature, he did not perform hard manual work, but he trained with sword and bow and rode a horse.

This master’s thesis deals with signal evaluation using Fourier transform. In the theoretical section, different methods of signal analysis with an emphasis on a Fast Fourier Transform are described. Theoretical section also contains description of common machinery faults and their diagnosis using frequency spectrum analysis. In the practical section, an algorithm for signal evaluation with an emphasis on coherence condition was designed in the Matlab environment. This algorithm was later used to evaluate submitted signals.

Master’s thesis contains the theory for realization of the researched software. Besides other, it describes Fourier transform, frequency response function, coherence, impulse response and group delay. Real life application of the software is discussed. Software is invented in the MatLab environment. Further, thesis provides testing of the software and shows its commented outcomes.

The aim of this thesis was automatic pitch detection in melodic guitar lines and subsequent transcription to guitar tablature. Final system uses comb filtering to detect pitch. Individual notes are separated by beat detection. An algorithm for transcription of notes to guitar tablature, based on minimalization of hand movement is proposed.

This thesis focuses on the measurement with the help of sampling cards and determination of the basic parameters of the measured signal. There will be described basic characteristics of the used card Alazartech ATS860- 256M and brief description of the programming languages which will control the cards. In these environments there were the created driving programs for the operation of these cards. Main measuring program was created in the language C\C++, that shall work as oscilloscope and the same time as spectral analyzer. This programme will determine basic characteristics of the measured signal. Further there will be created simple preparation for memasuring with this card. In the conclusion of this thesis will create instrutions for laboratory exercise.

This work deals with object speed measuring using image analysis method. The reader will become familiar with a mathematical theory upon which the method is based. The mathematical algorithm for obtaining the speed of a given object is illustrated. Furthermore, an original computer program has been developed and the results of real measuring are shown.
