X-ray Unit Parameters Optimisation Based on the Laboratory Type
RADMACHER, Erich
Despite the rapid development of modern imaging methods, the radiography has remained the basic tool in radiodiagnostics. Individual radiography laboratories need adequate instrumentation for their flawless operation. The parameters of an X-ray unit must correspond to the type and quantity of its output required. The first part of the dissertation describes an X-ray unit and its individual structural units, including their principle of function. The necessary X-ray equipment and tools are also described, as well as the generation of a radiographic image in film and digital radiography. The next part of the dissertation presents the questionnaire inquiry performed. The objective of the inquiry was to obtain data on the specifics of various types of radiographic laboratories and the X-ray units used. The qualitative and quantitative statistical data obtained are presented, and the effects of the unit{\crq}s various parameters on the laboratory{\crq}s workflow are evaluated, taking the users{\crq} judgement of the instruments into account. On the basis of the number of exposures and other data, the basic types of radiography laboratories are specified. In conclusion, the optimum configuration of the parameters of an X-ray unit for individual types of laboratories is proposed. The work could serve as an aid for the orientation of the selection committee when purchasing a new unit.

Title: Electrostatic generators Author: Michal Hnyk Department: Department of Physics Education Supervisor: doc. RNDr. Leoš Dvořák, CSc., Department of Physics Education Abstract: This bachelor thesis named Electrostatic generators is divided into four main parts. The first part deals with the role of experiment in physics teaching on primary and high schools and brings some important arguments why the experiment plays irreplaceable role in teaching physics. Second part deals with the explanation of principles of operation of some particular types of real electrostatic generators. Third part describes the concept of construction, its' improvements and experience with building of the Bonetti electrostatic machine, which can become a desirable instrument in schools thanks to its' properties and affordable cost. There are also results of measurements of some parameters of available generators mentioned. Fourth part consists of gathered school demonstrative experiments from electrostatics, which are chosen to match teachers' needs by their simplicity of performing and their applicability to demonstration of electrostatics for students. Keywords: electrostatics, generator, experiment

Europeanisation of Criminal Law
Oravcová, Martina ; Herczeg, Jiří (advisor) ; Gřivna, Tomáš (referee)
Europeanisation of Criminal Law Summary Throught the use of common adaptation of the basic principles of criminal law in the european dimension there is a possibility to remove an opacity and inefficiency of individual national and international instruments of criminal law so far. This effort can be the best observed in the procedures of the European Community or European Union. It should all happen by harmonizing laws and strengthening cooperation between the European Union member states. Integration of criminal law is pointed to be done in three main directions. First, it affects substantive criminal law by harmonizing particular merits of criminal offences. Second, it already affected criminal procedure by achieving mutual recognition of judicial decisions. The third way of integration is the institutional framework for judicial cooperation in criminal matters, followed-up by institutions of criminal cooperation. Criminal law as a public law is closely related to the state sovereignty. This fact, even today, suspends the opportunity to create sort of unified system of transnational criminal law within the European Union. Moreover, the very concept of criminal law is not clearly established in European law as it is in Czech law. For example, it includes even different illegal dealings than regular...

Orff's Schulwerk in the Preparation Process of Children's Choirs
Kopřivová, Jitka ; Pecháček, Stanislav (advisor) ; Váňová, Hana (referee)
In der Arbeit versuchte ich, die Prinzipien des Orff-Schulwerks in die Kinderchorarbeit zu übertragen. Obwohl wir einige Gedanken des Orff-Schulwerks schon bei Jan Arnos Comenius finden würden, über seinen Anfang und seine Entstehung können wir erst seit den Dreißiger Jahren des 20. Jahrhunderts in der Günther-Schule in München sprechen. Über die Zielsetzungen der Schule sagte ihre Gründerin Dorothee Günther folgendes: "Als ich 1924 die Günther-Schule gründete, war es meine Absicht, einen Weg zur Wiederherstellung der naturgegebenen Einheit von Musik und Bewegung - Musik und Tanz - zu finden. Ein Weg, der nicht nur für einige intuitive Künstler gangbar sein, sondern der eine pädagogische Lösung bringen sollte, die es ermöglichte, allgemein im Menschen wieder rhythmische Schwingung, Aufnahme- und Gebefähigkeit, Tanz und Musizierlust zu erwecken. Carl Orff, der Leiter der Musikabteilung, suchte passende Instrumente, die dem Charakter des Tanzes am Besten entsprechen würden und die nicht zu schwer zu spielen sein würden. Für diesen Zweck übernahm er einige klassische Schlaginstrumente und nach dem afrikanischen Vorbild konstruierte neue Xylofone, Glockenspiele und Metallofone, die wir heute unter dem Begriff "Orff-Instrumente" kennen. Die Spieltechnik darauf ist sehr einfach und sie sind für alle ohne...

Capital adequacy and its calculation based on the principles of Basel II
Petrák, Lukáš ; Dobrovolný, Marek (advisor)
This bachelor thesis deals with the New Basel Capital Accord, so-called Basel II, with a focus on the calculation of capital requirements for credit, market and operational risk. The work briefly examines the reasons for the regulation of the banking sector and the various instruments of regulation. The thesis addresses the development of rules for the calculation of capital adequacy as well as the various methods for calculation of capital requirements -- i.e., the basic and advanced methods. Furthermore the comparison of basic and advanced approaches for calculation of capital requirements within each risk is involved. Advanced approaches within each risk, i.e. approach based on internal ratings (IRB), the method of value at risk (VaR) and the approach AMA can be used by banks after previous agreement of the Czech National Bank provided many quantitative and qualitative requirements have been met. As a matter of fact, the Czech banks have not much employed the advanced approaches yet, but their utilisation is expected to increase year by year.

Kubičková, Alena ; Halámek, Josef (referee) ; Lhotská, Lenka (referee) ; Kozumplík, Jiří (advisor)
This dissertation thesis is dedicated to the heart rate variability and methods of its evaluation. It mainly focuses on nonlinear methods and especially on the Poincaré plot. First it deals with the principle and nature of the heart rate variability, then the ways of its representation, linear and also nonlinear methods of its analysis and physiological and pathophysiological influence on heart rate variability changes. In particular, there is emphasis on the metabolic syndrome. In the next section of the thesis there are compared and evaluated different ways of representation of the heart rate variability and further are tested selected methods of heart rate variability analysis on unique data from patients with the metabolic syndrome and healthy subjects provided by the Institute of Scientific Instruments, Academy of Sciences of Czech Republic. In particular, they are used the Poincaré plot and its parameters SD1 and SD2, commonly used time domain and frequency domain parameters, parameters evaluating signal entropy and the Lyapunov exponent. SD1 and SD2 combining the advantages of time and frequency domain methods of heart rate variability analysis distinguish successfully between patients with the metabolic syndrome and healthy subjects.
