Automotive fuels and their future in green transport
Mrázková, Kristýna ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor thesis deals with the problematic of currently most used automotive fuels and their impact on the environment. It briefly describes the development of combustion engines and provides an overview of most common automotive propulsions and their alternatives. The final chapter of the thesis deals with the problematics from socially political perspective.

Thermodynamic 1-D model of the turbocharger of an internal combustion engine
Mrázková, Kristýna ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
The thesis deals with 1D heat transfer simulation of turbine housing laying emphasis on temperature of exhaust gas leaving the turbine. The thesis covers construction and thermodynamics of turbochargers, SCR catalysts and 1D simulation software. Then the thesis focuses on exploring turbine housing 3D model discretization, building physical turbocharger model for 1D simulation of heat transfer through turbine housing with time dependent input values and predicting temperature of exhaust gas flowing through turbine outlet in compliance with NEDC cycle. Result analysis and a suggestion of subsequent actions follow.

Thermodynamic 1-D model of the turbocharger of an internal combustion engine
Mrázková, Kristýna ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
Master thesis deals with 1D heat transfer simulation of turbine housing laying emphasis on temperature of exhaust gas leaving the turbine. The thesis covers construction and thermodynamics of turbochargers, exhaust gas aftertreatment and heat transfer simulation software. Then the thesis focuses on exploring turbine housing 3D model discretization, building physical turbocharger model for 1D simulation of exhaust gas output temperature and heat transfer through turbine housing. Heat transfer coefficients were calibrated for transient simulation predicting temperature of output exhaust gas in compliance with NEDC cycle. Results analysis and optimization follow, a suggestion on model integration into the virtual turbocharger system is also included.

Analysis of mutual relations between the Czech Republic and China focused on the import position of a company M.A.T. Group, s.r.o.
Mrázková, Kristýna ; Zamykalová, Miroslava (advisor) ; Maxa, Jaroslav (referee)
The master thesis "Analysis of mutual relations between the Czech Republic and China focused on the import position of a company M.A.T. Group, s.r.o." describes the whole import process from China on an example of a concrete Czech company. The thesis is divided into five chapters. The first chapter is focused on mutual business and investment relations between the Czech Republic and China. The company itself is introduced in the second chapter of the thesis. The third chapter deals with the whole import process and describes all its parts. Following fourth chapter analyses selected problems related to the import process. Confirms or refutes the rightness of the solution, in case of need suggests a new one. The first part of the fifth chapter is focused on Chinese business conventions including culture specifics of Chinese businessmen. In the second part of the fifth chapter a SWOT analysis of the import position of the company is created, that summarizes all the information gathered during elaboration of the thesis, and proposes the import strategy of the company in business relations with China.

Strategy of a chosen Chinese company when entering the Czech market and building up a position on this market
Mrázková, Kristýna ; Zamykalová, Miroslava (advisor) ; Paleček, Martin (referee)
This bachelor thesis is divided into four parts. The first part is focused on mutual business and investment relations between the Czech Republic and China, further it presents the Chinese province Sichuan in more details and its relations with the Czech Republic. At the end of the first part it is mentioned an establishment of a company called Changhong Europe Electric s.r.o. The company itself is described in the second part of the thesis. This part deals with a parent company in Sichuan, company activities and offered products. An interesting section is the passage about cultural differences of Chinese employees. The third part is focused on marketing strategy of the company on the Czech market. It describes all parts of a marketing mix and a whole SWOT analysis of the company. The last part of this thesis deals with a company expansion to other European countries.

Ecological education in nursery school
MRÁZKOVÁ, Kristýna
Mrázková, K.: Ecological education in nursery school Insects and spiders as model taxon within ecological education in nursery school An educational proposal for work with pre-school children aimed at closer familiarization with life of insects and spiders has been elaborated. The submitted proposal has been developed into eleven incorporated sections connected through a motivational fairy-tale "Little George among beetles". Six of these sections have been tried out and in terms of field-test results and gained experience the implementation of remaining five is now being arranged. Work and grapho-motive sheets for children of pre-chool age have been also designed and presented with each topic.
