Analysis of cracking of aluminium profiles during bending process
Kalivoda, Ondřej ; Šebek, František (referee) ; Vosynek, Petr (advisor)
The presented thesis was created in cooperation with Siemens, s.r.o. and deals with the analysis of the bending of aluminium sheets. These products are used as conductors of electrical energy. The problem happened when the bending angle was 90 ° when there was a violation outside of the bend. The aim of the thesis is to verify whether the bend is correctly designed using analytical and empirical relations and the finite element method. Because of the requirement for running numerical simulation on one of the freely available software the Salome Meca program environment was used. The results of numerical simulation did not confirm that the violation should occur. In deeper analysis appeared doubts whether it is possible to correctly evaluated result only by data from tensile test. In the final part, there are recommended some experiments which would be necessary for the correct calibration of the ductil fracture criteria.

Protection against Discrimination under the European Convention on Human Rights
Konoplia, Oleksandra ; Lipovský, Milan (advisor) ; Pulgret, Miroslav (referee)
The thesis is focused on the examination of the scope of Article 14 of the European Convention of Human Rights, theoretical framework, and legal basis of the concept of discrimination. The paper presents an analysis of the caselaw of the European Court on Human Rights, how the latter operationalises the issue of inequality, and which inaccuracies of interpretation it leaves. The primary aim is to challenge the system of protection against discrimination under the Article 14 as well as the role of the national actors in its development. The thesis examines the level of compliance among signatories of the Convention with its anti- discriminatory provisions and focuses on the individual capacities of the states to satisfy judgements of the European Court on Human Rights. The usage of the comparative approach also helps to analyse the role of local non-governmental organisations in the process of compliance with human rights obligations under the Convention among signatories. The thesis aims to show why the level of protection against discrimination differs from the one country to another and which obstacles they face on the path towards the respect for human rights.

Hodnocení barvy medu
Černá, Eva
The aim of the thesis on "Evaluation of the color of honey" was to determine why the instrument can not Lovibond Honey Colorpod 440110 to evaluate color of all types of honey and compare results of with spectrophotometric measurement methods. The work is divided into theoretical and practical part. The theoretical part is dedicated to honey, its composition and methods of evaluating color. The practical part describes the results obtained instrument Lovibond Honey Colorpod -- 440110, spectrophotometers Konica Minolta -- 3500d a FT -- NIR Antaris. In UV/VIS region not been demonstrated reason of errors of photometer. Maximum lightness had a very light honeys and the largest share of yellow had light honey. The highest values of absorbance attain dark honeys. In color space CIE L* a* b* had the largest share of red. Evaluation of the color of honey in the UV/VIS can not prove adulteration of honey always unambiguously, but there are signs by which honey can be described as suspicious. By analyzing the NIR spectrum is falsification of honey demonstrated using discriminant analysis.

Mikroskopie medu a ověření jejího potenciálního významu pro zkoušení medu
Ležatka, Michal
This thesis deals with the microscopic analysis of honey and its use in the evaluation and testing of honey. The work is divided into theoretical and practical parts. The theoretical part is devoted to the analysis of pollen and physical and chemical methods of determining the type of honey. The practical part describes the results and compares them. 22 honey samples originating from beekeepers has been shown 17 beekeepers false claims about their type of honey. Of the 7 aldulterated honeys, 4 samples were violated by foreign particles from the environment. Further honeys from the market containing suspicious particles and very critically low pollen grains in 1 g of honey, which points to a adulteration of honey. Unifloral honeys from Olomouc were found honey from satureja (S/2) and lavandula (F/1) containing neither one pollen grain of these plants.
