Shielding and detection of neutrons
Černý, Tomáš ; Šťastný, Ondřej (referee) ; Katovský, Karel (advisor)
The master’s thesis provides an overview of available neutron sources in terms of neutron yields and energy spectrum of emitted neutrons. Reactions of neutrons with matter, especially neutron scattering and radiation capture, are described. The possibilities neutron neutron detection and spectrometry are also described. The following experiment deals with a design of suitable shielding materials and the analysis of the moderated energy spectrum of neutron flux. The properties of the neutron field were measured using detection by activation. Subsequently, a simulation of the problem was performer in the MCNP program. In the end, the achieved results are compared and evaluated.

Interactive methods of TV presenting (plasma,full graphics) and their usage in ČT24 news prgrammes
Gastová, Tereza ; Lokšík, Martin (advisor) ; Géla, František (referee)
In this thesis the author deals with the phenomenon of broadcast presentation with the help of graphic accompaniment, which is displayed on a large-format background during the studio performance of a news anchor. This thesis focuses on what the preparation and production of these articles entails, how they are handled and how various members of the television crew are involved in the whole process. This is achieved through interviews with several employees of the ČT24 news channel. Individual phases are represented by three selected programs produced by ČT24. Their broadcast throughout one specific day is then examined by the method of qualitative analysis of the content and describes which forms of interactive contributions were applied. The introductory part of the thesis offers basic theoretical background. It introduces the general concepts associated with the researched phenomenon and consequently deals with digitisation, the characteristics of ČT24 broadcast studios, and lastly, the role of the news presenters and news graphics.

Contractual penalty under the Commercial Code (with focus on the discretionary power of a judge to reduce a contractual penalty)
Mináčová, Michala ; Patěk, Daniel (advisor) ; Klee, Lukáš (referee)
Contractual Penalty under the Commercial Code (with focus on the discretionary power of a judge to reduce a contractual penalty) Contractual penalty is a concept frequently used by the parties to consolidate the position of the creditor as well as to motivate the debtor to fulfill the obligation as agreed. Not different from the other institutes of private law, the practical application of contractual penalty arises many questions with no uniform answers. The purpose of the thesis is to analyze selected contentious issues concerning the contractual penalty, especially discretionary power of a judge to reduce its unreasonable amount, to confront controversial theoretical opinions as well as non-conforming conclusions drawn from the juristic theory and established practice of the courts and add own opinion on the discussed matters. The paper does not include the exhaustive construction of contractual penalty, and therefore the general aspects are outlined only to the necessary extent. Greater attention is paid to the creation and existence of the right and claim to the contractual penalty. The study shifts the focus on the discretionary power of a judge to mitigate its inappropriate amount comprising different opinions on the related issues. The concept of contractual penalty has been used in private...
