Study on dependency of the weld geometry on process parameters in laser hybrid welding of aluminum alloy
Wojnar, Michal ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
A study carried out in the bachelor 's degree in engineering technology deals with changes the geometry of the weld technologies created laserTIG . The theoretical part provides an overview of the basic characteristics and advantages of welding technology laserTIG a summary of the issues welding of aluminum alloys. The experimental part consists in the execution of fifteen test welds on a sheet of Al alloy 2024 tl . 3 mm. From the measured values of individual welds were prepared according to the depth and width of the seam TIG welding current at a constant laser power and dependence on a specific area of the weld heat input Qs. By comparing the dependencies have been demonstrated theoretical advantages of laser hybrid technology , which consist mainly of increasing the welding speed and lower heat load of the welded material. Using the laser hybrid welding for welding of aluminum alloys proven advantageous.

Economical and trade aspects of defense industry
Wojnar, Michal ; Černá, Iveta (advisor) ; Bolotov, Ilya (referee)
The master thesis "Economical and trade aspects of defense industry" is aimed at analyzing the relationship between defense suppliers and a government. The thesis describes the conditions under which the market is inefficient and causes of government failures. The important principle is the one of Pareto efficiency, which serves as a efficiency benchmark of economic allocation. The thesis has utilized theoretical methods to analyze individual aspects of international arms industry - both economic and non-economic.

Marketing Strategy of a Chosen Product on The Example of DuPont
Wojnar, Michal ; Zamykalová, Miroslava (advisor) ; Vacín, Otakar (referee)
The bachelor thesis "Marketing Strategy of a Chosen Product on The Example of DuPont" is aimed at analyzing the marketing strategy and marketing mix of the Elvaloy material which is used in paving segment. The main applied methodology is called situation analysis through which the author compares individual key markets, reviews internal and external conditions of the company and studies the competition. The main objective of the thesis is also to present diminishing differences between industrial and consumer marketing and creation of new hybrid marketing concepts. As a main motive force of this step change is in this case considered globalization and its associated effects.
