This diploma thesis deals with issue of maritime piracy, which is nowadays one of the significant international problems. Maritime piracy has substantial economic and other consequences, which increasingly motivate the international community to solve the maritime piracy problem. This thesis primarily focuses on these consequences and on ways of solving the maritime piracy problem.

This diploma thesis explains nonverbal physical tasks in the teaching of physics. The first chapter focuses on the teaching of physics at primary school, marginally educational programs, teaching methods and physical tasks. One chapter also explains creativity and its use in teaching the subject. This thesis includes a set of processed nonverbal physical tasks together with their didactic analysis and solution of some exercised. Some of the mentioned tasks were processed into worksheets, verified by practice and evaluated. The results of verified nonverbal physical tasks are also attached in the diploma thesis.

The main aim of diploma thesis is to create a collection of tests which helps the students to prepare for the admission exam to eight - year grammar school. The theoretical part of diploma thesis focuses on the admission exam in school year 2016/2017 and the analysis of mathematical didactic test. The practical part contains a processing of seven tests. Each test includes a task, a solution and an answer key. Furthermore, the research is processed here for which the second test from diploma thesis has been used. Even children participating in mathematical Olympiad can use the tests from diploma thesis for practising. The teachers can also make mathematics lesson more varied by the right choice of exercises.

1 Title Helical symmetry and the non-existence of asymptotically flat periodic solutions in general relativity Author Martin Scholtz Department Institute of theoretical physics Faculty of Mathematics and Physics Charles University in Prague Supervisor Prof. RNDr. Jiří Bičák, DrSc., dr. h.c. Abstract. No exact helically symmetric solution in general relativity is known today. There are reasons, however, to expect that such solutions, if they exist, cannot be asymptotically flat. In the thesis presented we investigate a more general question whether there exist periodic asymptotically flat solutions of Einstein's equations. We follow the work of Gibbons and Stewart [3] who have shown that there are no periodic vacuum asymptotically flat solutions an- alytic near null infinity I. We discuss necessary corrections of Gibbons and Stewart proof and generalize their results for the system of Einstein-Maxwell, Einstein-Klein-Gordon and Einstein-conformal-scalar field equations. Thus, we show that there are no asymptotically flat periodic space-times analytic near I if as the source of gravity we take electromagnetic, Klein-Gordon or conformally invariant scalar field. The auxilliary results consist of corresponding confor- mal field equations, the Bondi mass and the Bondi massloss formula for scalar fields. We also...

In this work we study inhomogeneous cosmological models. After a brief review of applications of inhomogeneous solutions to Einstein equations in cosmology, we give a short description of the most widely used inhomogeneous cosmological models. In the second chapter we study in detail geometrical prop- erties of the Szekeres spacetime and we are concerned with the interpretation of the metric functions in different types of geometries. In the last chapter we model inhomogeneity in Szekeres spacetime. We derive formula for the density contrast and investigate its behaviour. We also derive conditions for the density extremes that are necessary for avoiding the shell crossing singularity in Szekeres spacetime. 1

The topic of my master's thesis is the musical Cabaret, written by the original writer of the book Berlin Stories by Christopher Isherwood. The Cabaret musical has been created through collaboration of John Kander (music), Fredd Ebb (lyrics) and Joe Masteroff (libretto). At the beginning of my thesis I mention history of the cabaret and its development. Then I try to explore the origin of the cabaret in Paris, its birthplace, and also in Germany and in Bohemia. Another topic is the history of the musical, its principles and operations. In the next part of my thesis I analyze theatrical terminology which is closely associated with the Cabaret. In the practical part, I solve questions of the musical's storyline; this part also includes solutions to every piece of the story-pictures and also my own custom concept of set design and a space. The thesis also includes inspirational materials that assisted me to find the final solution.

This thesis is focused on scenographical treatment and conception of Shakespeare's play Titus Andronicus. Beside the historical and theoretical outline of the time of the play's creation, the thesis analyzes selected Czech and foreign productions of this play, with regard to its conceptional and graphic aspect. Furthermore, the thesis focuses on a complex analysis of the scenographic concept itself, and the graphic procedure as well. Thesis also marginally examines the central characters and the treatment of costumes. The goal of this thesis is to approximate the graphic treatment of a specific play and to describe processes of searching for own and personal graphic procedure used. This thesis is not only a historical analysis; it is also a subjective view of the issue given, that is supposed to approximate the specific scenographic adaptation of the play to the reader.

This work deals with the complex by treatment staging all the necessary components of the hand of the performance. Copy and analysis of already existing staging in America, the issue of homosexuality and transferring it into the artistic components of a dramatic situation, overhead construction and the creation of specific images and historical sources relevant to the concrete subject. The last section is devoted to the complete concept of staging the stage design and the costume design perception of music, moods and specific images.

The thesis is based on scene designs for the play Lady from the sea. I focused on the concept of the game from the perspective of the actual playwright, Henrik Ibsen. To get a wider range of designs I decided to choose a modern staging by Robert Wilson and Luboš Hrůza. My goal was to accommodate the production as a source of inspiration and guidance on how to dispose the scene in my own design.

This thesis is focused on creating and using the nonverbal physical tasks for teaching Physics. Firstly the general look at Physics education at elementary schools is taken as well as examining of the possibilities of the motivating in teaching. Physical tasks typology, its importance and inclusion in the teaching process are described. This paper introduces with nonverbal physical tasks, with their creation and their possible solutions. The main part of this paper is to create nonverbal tasks including didactic analysis. Some of these tasks are tested in practice and evaluated for their applicability in physics teaching. Result of this testing is included in the thesis.
