	Design of the test rig for the observations of the lubricant distribution in the rolling bearing Okál, Michal ; Hartl, Martin (referee) ; Košťál, David (advisor) Given diploma thesis deals with the design and realization of a device whose purpose is to simulate real condition in the contact area of deep groove ball bearings. Direct observation of such area was then carried out. Initial part of the thesis addresses principles occurring in ball bearings, such as friction and lubrication and wear mechanisms. Several devices which are commonly used for bearing lubrication studies are then described at the work. Subsequently, author’s solution was introduced with the output of Ball-on-ring device. Ball-on-ring configuration is key feature due to its geometry since it enables to create identical conditions as those which occur in ball bearings such as contact pressure and velocities. Lubricant distribution by the contact area is analysed with fluorescent microscopy. Part of this thesis is a validation experiment and drawing documentation of the device. Detailed record
	Modification of the test rig for the testing the bearings for the space applications Okál, Michal ; Křupka, Jiří (referee) ; Košťál, David (advisor) This bachelor thesis deals with the design of a device, which allows exploration of rolling bearings properties in space conditions. The adjustment is necessary for testing of a new rolling bearing with different dimensions. Preload of the bearing must be centered and adapted for rapid heat exchange with the surroundings. The effort is made to use maximum number of existing components and torsion stiffness of the device. The thesis outputs are the accompanying report and the technical documentation allowing the production of new components. Detailed record
	Identification of Leadership Competencies in a Global Organization Kuric, Matej ; Okál, Michal (referee) ; Konečný, Štěpán (advisor) The aim of this diploma thesis is to identify a key competencies for a leader in global corporation respecting the regional differencies. In the theoretical part we define leader, point out the differences between leader and manager and analyze the required competencies of a modern leader. In the practical part, he analyzes the leadership settings in the selected company and compares the acquired knowledge with the theoretical definitions. On the basis of the results obtained, it suggests specific ways of developing selected personality traits while accepting regional differences. Detailed record
