The (Social) Construction of Scientific Fact
Jedlička, Petr ; Balon, Jan (advisor) ; Kandert, Josef (referee)
The thesis draws from the examples of the knowledge of two time periods - the Middle Ages and the Early Modern Era - to discuss the claims of the constructivist school of the sociology of knowledge. The first part provides a detailed account of the views of the key constructivist figures Ludwik Fleck, David Bloor, and the anthropologist of knowledge Yehuda Elkana. The following chapter examines the main characteristics and dynamics of the medieval religious discourse with the use of Elkana's concept of images of knowledge. The next chapter provides an account of the key period of Early Modern science and shows the rise of the empirical and rational paradigm and the introduction of scientific methods, as well as the broader social context of this process. The changes in the hierarchy of knowledge are primarily demonstrated with the examples of the English natural philosophers and society during the Age of Restoration. Special attention is devoted to sources of knowledge and the methods of their legitimization and verification during both periods, in addition to an examination, based on the Strong program, of the societal roots and factors determining or influencing that knowledge. Are the tenets of the Bloor's thesis, which put forward the idea of a strong social component of knowledge, valid? Is...

Solvency Internal models
Mertl, Jakub ; Cipra, Tomáš (advisor) ; Mazurová, Lucie (referee) ; Jedlička, Petr (referee)
Title: Solvency Internal models Author: Mgr. Ing. Jakub Mertl Abstract: The subject of thesis is assessment of calculation methods on capital adequacy of currently implemented regulation in insurance industry called Solvency II. The aim of the thesis is to build up a partial internal model fulfilling the condition of Solvency II. The thesis deals with the premium and reserve risks that are essential part of non-life business. Different approaches of risk assessment are described and aggregation of those risks as well. An important part of the thesis is a numerical example illustrating presented methods.

Noise meter and sound detector
Jedlička, Petr ; Novák, Marek (referee) ; Povalač, Aleš (advisor)
This work deals with design and construction of a noise meter, which measures sound pressure level. The device can be set either for weighting filter A or for weighting filter C considering the characteristics of human hearing, the device also allows two modes, fast and slow, depending on the rate of changes of sound pressure level. It tis possible to send measured data to a PC through a measuring application. The noise meter can be powered either by three AA batteries or by a PC through USB interface. The noise meter can be controlled by voice commands.

RF analog fiber optic link
Kelbler, Petr ; Jedlička, Petr (referee) ; Drexler, Petr (advisor)
This thesis analyzes the problem of design analog fiber optic link for transmission high frequency signals. Analog fiber optic link will be used in system for detection and localization a partial discharge activity MOSAD-PD-UHF, where will replace existing solution with coaxial cables, which is not appropriate for highly noise environment. MOSAD-PD-UHF system is developed in department of theoretical and experimental electrical engineering. At the first, MOSAD-PD-UHF system and individual parts of optical chain are theoretical described. In following part are compared a few commercially available analog fiber optic link and design of chosen transmit and receive module are described. . The thesis final part deals with construction of optical link and measured parameters are discussed.

Munich chain ladder method
Janáková, Veronika ; Pleška, Martin (advisor) ; Jedlička, Petr (referee)
Title: Munich chain ladder method Author: Bc. Veronika Janáková Department: Department of probability and mathematical statistic Supervisor: Mgr. Martin Pleška Supervisor's e-mail address: martin.pleska@cz.pwc.com Abstract: The insurance company is obliged to create technical reserves to cover the risk from insurance activities. One of the main reserves in non-life insurance is the IBNR reserve - the reserve to cover the damages that already exist, but that have not been reported to the insurance company yet. The content and the general aim of this thesis is to provide a better orientation in the method used in the estimation of the reserve IBNR - the Munich Chain Ladder Method. Munich Chain Ladder Method was created as a modification of the standard Chain Ladder calculation - one of the most used methods in the estimation of the IBNR reserve. The thesis focuses on the reasons that led to the modification of standard Chain Ladder calculation and explains the calculation of the modified method. It presents the application ot the method on the real data as well as the comparison with the results of the classical and less complicated Chain Ladder method. Keywords: IBNR reserve, chain ladder, Munich chain ladder 1

Statistical Properties of the Estimate of Non-Life Insurance Technical Reserves
Pechanec, Jan ; Cipra, Tomáš (referee) ; Jedlička, Petr (advisor)
In the presented work we study two different statistical methods for estimating IBNR reserve that is a part of the reserve for outstanding claims reserves. The first method is stochastic version of the Chain ladder method and the second one is a PTF model. We describe theories of the methods and show their different properties. The Chain ladder method does not assume any distribution of claims amount, on the other hand PTF models assume normal distribution of logarithms of incremental data. In practical part of this work we apply both methods on illustrative data and then we compare the results. We inspect especially probabilistic distribution of estimate of reserves and their statistical characteristics. An important part of this work is statistical testing of assumptions of both methods.

Radio frequency resonator for feeding ion trap
Jedlička, Petr ; Pham, Minh Tuan ; Čížek, Martin ; Pavelka, Jan ; Lešundák, Adam ; Hucl, Václav ; Hrabina, Jan ; Řeřucha, Šimon ; Lazar, Josef ; Číp, Ondřej
Two versions of resonators were designed and manufactured - asymmetric and symmetric.\nThe resonator consists of a coil and capacity of ion trap which makes parallel resonant circuit.\nEnergy is supplied to the resonator through the coupling inductance. Resonator assembly was equipped with outputs for monitoring high-frequency voltage. Both versions have been tuned and tested.\n\n
