Materials for Production of Chords for Musical Instruments
Krhut, Štěpán ; Němec, Karel (referee) ; Molliková, Eva (advisor)
My bachelor’s work is about materials used for making the musical strings and its protection against its wear off. The introduction deals with evolution and history of the musical strings and the next chapters explain physical basics of the vibrations and how to make the musical string. There are also highlighted and many times mentioned guitar strings in my work due to the string manufacturers are made to develop and implement various high level demands into the strings because of the many various guitar playing techniques.

My diploma work is an installation, made from multiple instances of a device iniciating string resonance via electromagnetic field. These devices along with strings are placed on the wall in geometrical shape. Installation creates loop on multiple levels. Except the fact that installation have a circular shape, position of each string starts at the end of another string. Second, more inconspicious loops takes place in the electromagnetic device resonating the strings, that do that with feedback loop. Strings consist every step of chromatic scale, that repeats itself, just an octave higher. Amplification of the final sound of strings is done purely acoustically, with help of the wall on wich the piece is installed. This piece is in its nature concerned with spirituality in music, not necessarily in sense of evoking a spiritual experience, but rather demonstrating metaphors and parallels, that exists between physical aspects of tonal music and different religious ideas. The symmetrical shape of installation refer to religious and occult visuality, built f.e. in cabal on Fibonacci numbers, that is present not only in nature ( for example, the veins of the leaves grow by these numbers), but also in tonal music system (ancient philosophers were working with this concept, see Plato's Music of the Spheres). Strings in this piece produce drone sound, that is naturally evoking spirituality (most visible in buddhist monk meditation). This sound in the piece demonstrates immutability and constancy, the fact that all the chromatic tones are playing demonstrates wholeness (this fact may produce interesting resonances emerging between chromatic steps), so to speak, the unchangeable laws of physics, or to put it in religious lingo, the god law. The symbol of loop also refers to religion, like the eternal return of the same, the periodicity of history. Strings can be viewed as astrophysical symbol. Everything stated is nothing but my recourse, that should not ultimately determine the perception of the piece by viewer. The goal of the work is to offer experience without need to be put into context

Record Linkage in Genealogical Data
Šorm, Jan ; Rozman, Jaroslav (referee) ; Zbořil, František (advisor)
The main aim of this thesis is to study genealogical data, to find out possible problems in their merging and to implement methods for this data merging. In this thesis, it will be studied the problem of classifying similar names into common classes. This problem will be studied mainly because people's names and surnames play the most important role in every registry entry. In this thesis, it will be analyzed several metrics for calculating the distance between two strings. In addition, several experiments will be done for these metrics to classify names into classes with as few errors as possible. Based on these results, experiments for record linkage will be performed.

Spacetimes with accelerating sources
Vrátný, Adam ; Podolský, Jiří (advisor) ; Krtouš, Pavel (referee)
The core of this thesis is the analysis of accelerating black hole solution with the NUT parameter, which was found by Chng, Mann and Stelea in 2006, and related spacetimes. The original work consists of three interconnected parts. In the first chapter we study the Taub-NUT solution, in particular the nature of its pathological axes, and we include a number of visualizations. In the second chapter we investigate the accelerating Taub-NUT solution, we present it in a new form, and we discuss its "deviation" from the Pleba'nski-Demia'nski class of solutions. To see the differences more clearly, in the final chapter we put also the Pleba'nski-Demia'nski metric into a completely new factorized form. The work is concluded by discussion of special subcases, from which it is clearly seen that the Pleba'nski-Demia'nski class does not contain the accelerating Taub-NUT solution.

String Analysis for Code Contracts
Dort, Vlastimil ; Parízek, Pavel (advisor) ; Kofroň, Jan (referee)
Using contracts such as method preconditions, postconditions, and class invariants in code is an approach to preventing bugs in object-oriented programs. In the .NET Framework, this is possible due to the framework of Code Contracts, which includes Clousot, a tool for static program analysis based on abstract interpretation. Although string is a fundamental type in .NET programs, Clousot does not have a usable support for analysis of string values. In this thesis, we explore the specifics of string manipulation in the C# language and in the .NET Framework, and show how they can be covered by static analysis. Our approach is to use the methods of the String class and a subset of regular expressions to specify string properties in code, and to use abstract interpretation with non-relational abstract domains to reason about those properties. We chose a small number of already published abstract domains for strings, which vary in their complexity and ability to represent different properties. We adapted those domains to our setting, including definitions of abstract semantics for the supported string methods. We implemented the abstract domains in Clousot in a way that cooperates with numerical analysis and allows adding more string abstract domains in the future. Powered by TCPDF (www.tcpdf.org)
