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.

Monitoring of the influence of indigenous culture of yeasts on the fermentation process of making wine
Michálek, Petr ; Molnárová,, Jana (referee) ; Vránová, Dana (advisor)
This thesis deals with the identification of wine yeasts isolated from the grape must using PCR-RFLP method. The yeasts were isolated from Pinot Noir grape variety must. Grapes were grown and produced in accordance with the requirements placed on organic and integrated farming. Samples were processed in the laboratory, where pure cultures of individual yeast were obtained. A commercial kit was used for yeast DNA isolation. Obtained DNA was used for further analysis. Using the polymerase chain reaction and the primers ITS1 and ITS4 a specific segment of 5.8S rDNA-ITS region was amplified. The PCR products were then detected by electrophoresis in an agarose gel, and after a subsequent purification, three restriction enzymes: HaeIII, HinfI and HhaI were subjected to restriction analysis. The DNA was digested to fragments specific for yeast species and they were detected by agarose electrophoresis. Similarity of these isolates was compared using BioNumerics program and the result is dendrogram of genetic similarity of isolated yeast. The basic chemical analysis of samples must was also performed.

Comparison of Instrument Transformer and Sensor Applications in Feeder Terminal REF 542plus
Hrycík, Tomáš ; Majer, Karol (referee) ; Orságová, Jaroslava (advisor)
The aim of this Master´s thesis is use of instrument transformers and sensors on field of industry protection. We will compare current and voltage transformers, current sensor – based on Rogowski coil, voltage sensor – based on voltage divider. By this measure devices, we can monitoring values of analog quantities in medium voltage switchgear. It is impossible to compare, measure and analyze without this measure devices. There is protection terminal REF542plus, which can compile this values. The REF542plus ability are measuring, monitoring, remote control and protection. First, we will discuss about theory of sensors and convential instrument transformers and analysis of analog signal. We will compare analog input channel on sensor´s analog module and transformer´s analog module. There are few differences between type of analog modules. For analog signal analysis are important frequency filters and Analog/ Digital Convertor (sigma-delta). We will describe functions and options of REF542plus. In practical part of this project, we will test protection functions of protection terminal. First, protection terminal will be connected to sensors. Second protection terminal will be connected to transformers. For testing we chose Earth-fault directional protection and differential protection. We will make only secondary tests. That´s mean, input analog quantities to REF542plus will be simulated by tester. In all we will verify quality of protection. We will focus on lower settings of protection and we will inject protection by low current. Objectives are testing of trip characteristics and measuring of trip time.

The specifics of management (leading) personnel selection within the Czech education system compared with the management personnel selection within a non-educational field
Strejcovská, Barbora ; Krutská, Dagmar (advisor) ; Hamerníková, Dana (referee)
My bachelor thesis deals with the difference between the selection and subsequent allocation of human resources to managing posts within the educational sphere and commercial sector. The thesis is based on longitudinal monitoring of the described differences and uses basic knowledge of personal psychology including modern psychological methods of personality typology. The thesis works with the results of an elementary empirical examination of persons within the educational, noneducational, public and private sector, based on the outputs of MBTI personality questionnaire ((Myers-Briggs Type Indicator). The aim of the thesis is not only to describe the basic differences of both approaches. It also tries to offer elementary or rather basal solution proposals as a part of the currently in progress changes within the Czech educational system, using inspiring material of the so called White Book of the Ministry of Education, Youth and Sports. Practical use of this paper lies above all in the field of the optimalization of the use of school management human resources and that is in direct relation to schools established by the Prague City Hall.
