Protection of Buildings Utilizing Components of I&HAS
KANDL, Jiří
In this work I have analyzed possibilities of protection of buildings utilizing components of "Intrusion and Hold-up Alarm System". (Hereinafter: "I&HAS"). The first part of this work deals with description of basic terminologies and definitions from the area of protection of buildings, as well as description of elements utilized by I&HAS systems; electrical fire alarm systems and camera systems - the aim of the work is not to encompass full details of the above systems but to create a general overview of terminology. The practical part of my work focuses on a proposed intrusion protection of a family home, exploring three different degrees of its protection, with a different degree of ensuing risks. Furthermore, measurements of realistic intrusion system components were carried out - sensor characteristics of motion detectors, audibility of sirens and, qualities of video outputs of different types of cameras were also investigated.

The Developement of Art Creativity through Project Method
MACHÝČKOVÁ, Veronika
The thesis deals with general creativity and creativity development of adolescent children by the means of project method. Theoretical part describes creativity as a term, its factors and levels. It further characterizes these terms: creative activity, creation, creative thinking, brainware, and creative experience. Further it analyses creativity importance for an individual person and society as a whole. It also characterises creative type of personality, describes pedagogical creativity and offers ways and means of creativity support. Next part draws up creative thinking development possibilities and development possibilities of qualities important for creative personality development. Next chapter pursues project method character. It describes case-history, then it targets the project-problem relation, highlights project education effects and basic principles. It focuses on phases of the project process and project pattern overview. In following chapters school subject art education, its characteristic, its main goals, and art education pedagogy methods and forms are described. Artistic expression development and crises of artistic expression are described, too. The thesis further concerns leisure time, extracurricular education and its institutions, relations of leisure time, lifestyle and focus on social values. Last chapter considers adolescence. Practical part contains description of an art project, which is divided into several creative activities. This part is focused particularly on spontaneous expression of a group supporting.

Propagation of inclined cracks to the interface of ceramic laminates
Novotná, Lenka ; Trunec, Martin (referee) ; Chlup, Zdeněk (advisor)
Composite materials with laminated structure provide advantages which are utilised during component design. Low density, temperature and chemical stability are the profitable properties predetermining application of ceramic laminates. The main obstacle for wide spread of ceramic materials is their inherent brittleness. Therefore, in this thesis, the crack propagation in ceramics laminates has been extensively studied. Laminated structures with various volume fractions of components (alumina and zirconia) were prepared by electrophoretic deposition. Evaluation of crack propagation through the interface and determination of basic mechanical properties was conducted on the basis of extensive literature search. Crack deflection originated in both presence of internal stresses and differences in elastic modulus during the crack interface passing was monitored. A special type of specimen geometry was employed with the aim to set arbitrary angle between crack and interface. It was experimentally found that the degree of crack deflection is dependent on entering angle and volume fraction of components. Higher crack deflection was already found in the bulk of the test piece comparing to the test piece surface. The 3D fracture surface reconstruction generated using laser confocal microscopy was used in this detailed crack propagation study. Further basic elastic and strength characteristics of laminates were determined and compared to those obtained from monolithic materials. The validity of the mix rule for elastic characteristics was confirmed by comparing of elastics modulus. The most reliable method for elastic modulus determination was marked the dynamic resonance method due to low scatter and consistency in measurement. The flexural strength of all laminates tends to be close to the flexural strength of the weakest component. Therefore the mix rule is not applicable for flexural strength estimation on the contrary of elastic characteristics. The change of component volume fraction leads only to change of flexural strength scatter. Thanks to gained knowledge about crack propagation and basic characteristic determination will be possible to design ceramic laminates more efficiently for given needs of application.

Legal status of civil servants in the Czech Republic
Blažek, Jaroslav ; Matula, Miloš (advisor) ; Rys, Rudolf (referee)
The Master's thesis is dealing with the issues of the civil service, which development and current situation show considerable heterogeneity of opinions and related political dispute. A closer look on current condition, is preceded by the outline of the characteristics of civil services' basic characteristics distinguished by current legal theory. A historical excursion since 1918 with respect to chronological and semantic order, has also been made. The crucial part of the thesis is devoted to the content analysis of the service pragmatics, the bill of The state officials and Service Act and its amendments. In the conclusion, the author defines four variants of possible solution to the current state of the civil service, which, among others, indicate, that it is desirable to revise effective Service Act by the Bill no. 71/9, with respect mostly to career elements and current situation of the civil service.
