Changing international environment and the new threat. A chance for European strategic culture?
Bartík, Lukáš ; Martinková, Viera (advisor) ; Földes, Kristián (referee)
Changing international environment and new threats. Opportunity for a European strategic culture? The international environment is going through a period of major upheaval. Terrorism, the growing influence of emerging powers and authoritarian regimes, and the weakening of multilateralism contribute to the gradual deterioration of the world order and simultaneously represent a serious challenge to Europe. In the aftermath of the Russian annexation of Crimea in 2014, the vulnerability of the European security architecture became especially apparent. This thesis aims to unfold how these changes were perceived and responded to by two major countries of the European Union: France and Germany. The main focus is on the perception of these changes, the security challenges and the relationship with Russia and its confrontational policy towards Europe and the surrounding areas. Furthermore, it deals with their perception of the changing foreign-policy priorities of the United States and the deepening of European cooperation in the field of security and defense policy. The analysis of the German and French discourse depicts their attitude and then compares their approach to the changing international landscape, thus answering the question of the compatibility of their respective strategic thinking.

Study of tropospheric chemistry using regional climate model RegCM4 and chemistry transport model CAMx
Bartík, Lukáš ; Huszár, Peter (advisor) ; Bednář, Jan (referee)
The subject of this diploma thesis is study of the impacts of different implementations of turbulence and convection in the Regional Climate Model (RegCM, version 4.6) on the ability to predict the chemical pollution of the troposphere in Europe, which was simulated by the chemical transport model CAMx (Comprehensive Air quality Model with extensions, version 6.50) driven by RegCM meteorology using offline coupling of theese two models. Thesis also includes a brief description of the tropospheric chemistry, a discussion of the influence of meteorological conditions on changes in pollutant concentrations in the troposphere, a brief introduction to the regional climate modeling, a description of both models and method of their coupling. The main focus of the thesis is the analysis of the impacts of different parameterizations in RegCM model simulations on some climatic elements, validation of air temperature and precipitation, analysis of the impacts of changes in driving meteorology on ozone, nitrogen dioxide, sulfur dioxide and fine aerosol, validation of model concentrations of these pollutants with measurements at rural monitoring stations and comparison of column concentrations of nitrogen dioxide with satellite measurements.
