Workability study 3D metal printing as technology for prototype plastic parts manufacturing
Kovář, Tomáš ; Herčík, Tomáš (referee) ; Sigmund, Marian (advisor)
This bachelor thesis is focused on the feasibility of metallic 3D printing. The 90MnCrV8 tool steel die is time consuming and expensive to manufacture by conventional methods. When considering the use of a die for a maximum of 50 pieces of moldings, it is possible to choose a material other than tool steel. From the offered possibilities of metal 3D printing, 2 suitable methods were selected, namely SLM and WAAM, where the WAAM method appears to be cheaper. Available materials for steel replacement 90MnCrV8 are metal wire G4Si1 for WAAM method and stainless steel X2CrNiMo17-12-2 for the SLM method. After listing all the options and evaluations, it can be seen that the feasibility of metallic 3D printing as a replacement for conventional tool production is possible.

Reform of the United Nations Security Council
Křesinová, Dominika ; Rolenc, Jan Martin (advisor) ; Lehmannová, Zuzana (referee)
The United Nations is an international organization founded in 1945. It is obvious that the status quo from that year cannot reflect the needs of present world. Because of this fact it is necessary to approach a reform. But the question is what the reform should deal with. There are plenty of reforming efforts in discussion. These proposals do not take into consideration only the reform of the Security Council but also other bodies within United Nations. In my thesis I will focus only on reforming the Security Council as a main body of the whole organization that should be able to react on security threats flexibly. The feasibility of UN reform depends on the agreement of the permanent members that can due to their veto right block any of the proposals. And for the time being, they use their privilege to do so because they are afraid of limitations of their rights and position. We cannot come up only with a clear proposal how to reform but also it is necessary to focus on the proper arguments why the permanent members should agree with the reform. The main target of the following master thesis is to find out whether the reform is feasible based on accessible information with respect to hindrances and positions of permanent members that are currently more passive than active.

Feasibility study of a small retail enterprise
Drugda, Marek ; Střížová, Vlasta (advisor) ; Jánský, Filip (referee)
This thesis describes the individual aspects of retail entrepreneurship of a small enterprise using the knowledge of large retail entrepreneurs. It introduces the business strategy of a clothing retail shop in Prague with an innovative business model, evaluates the external environment of the enterprise and its influence on the industry, outlines the procedures for managing specific areas of the operation and evaluates the feasibility of the enterprise utilizing a break even analysis and a cash flow forecast based on predefined criteria.
