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.

Causes of Civil Wars: The Influence of Natural Resurces Extractive Technologies on the Probability of Civil War Outbreak
Klosek, Kamil ; Karásek, Tomáš (advisor) ; Plechanovová, Běla (referee)
This study aimed to provide more general knowledge about the mechanisms which link natural resources with civil war outbreaks. The theoretical point of departure was the feasibility hypothesis hypothesis of Collier et al. (2009) in which the authors state that the paramount interest of researchers of civil wars should be directed at the structural conditions within a country. One of their assertions pertained to the role of natural resources. Those provide a potential revenue source for insurgents to finance their rebellion. Hence, the higher the dependence of a state on natural resource exports, the higher should be the probability of civil war outbreak. However, this account was heavily criticized by other researchers. Some claimed that the conceptualization of the Primary Commodity Exports (PCE) variable does not cover relevant natural resources (Fearon 2005), others pointed at the problem of reversed causality and endogeneity (Gleditsch 1998) and also others stressed to differentiate between different natural resources according to their proneness to be looted by rebels (Ross 2003). In order to address these problems, a new variable was conceptualized. The "extraction feasibility" variable measures the degree of extractability of a particular resource. It is composed of two notions, namely...

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.

Feasibility štúdia projektu výroby biomasy
Karaba, Ján ; Fotr, Jiří (advisor)
The objective of this thesis is to assess the overall feasibility of a biomass production project in the current business environment in Slovakia. The project is analyzed primarily in terms of market conditions, technical and technological details and economic feasibility. An important part of the study is also the risk analysis including various scenarios and an assessment of the influence of risk factors. The thesis concludes that the project is essentially feasible and has a potential of being successful although it bears a certain level of riskiness which has to be considered and managed.
