Calculation of DC electromagnet and its experimental verification
Steidl, Adam ; Vetiška, Vojtěch (referee) ; Valenta, Jiří (advisor)
Content of this thesis deals with electromagnets as operating elements in electric machines. Thesis is divided in two main parts, theoretical and practical. The theoretical part describes electromagnets as electric machine , usage of electromagnets in electrical devices as operating element. Electromagnets are further divided in groups on basis of different criteria. Next, the theory of electromagnetic fields and methods of assesment of static pull and dynamic characteristics is described. Construction and function analysis of researched electromagnet with permanent magnets, which serves as trigger in compact circuit breaker, is also included in this part. Practical part includes measurement of force quantities of researched electromagnet in different operating states an its evaluation. For analysis of dynamic quantities with finite element method were created two-dimensional and three-dimensional models. Evaluation of analysis follows. After that is described simplified design of electromagnet, based onoperating states of researched electromagnet. This part is closed with comparation between results of analysis and designed values of electromagnets.

The theoretical part describes electromagnets as an electric machine, usage of electromagnets in electrical devices as operating element. Electromagnets are further divided in groups on the basis of different criteria. Next, the theory of electromagnetic fields and methods of assesment of static pull and dynamic characteristics are described. Construction and function analysis of researched type of electromagnet from OEZ company with permanent magnets, which serves as trigger in compact circuit breaker, is also included in this part. Practical part includes measurement of force quantities of an electromagnet in different operating states and its evaluation. For analysis of dynamic quantities with finite element method was created suitable three-dimensional model of electromgnet. Model is used for simulation ofdifferent operating states.The last part describes measurement of dynamic characteristics of the electromganetic system. This part is closed with comparation of results.

Optimizing the Manufacturing Process in a Company
Vrána, Jakub ; Novák, Viktor (referee) ; Videcká, Zdeňka (advisor)
This thesis deals with the management of the production process, focusing on unproductive activities. It comprises analysis of the current situation in the company Teva Czech Industries s.r.o. (the TCI) and suggestions for improvement measures. The first chapter presents theoretical basis for processing work. PMT methods, namely MTM and MOST, lean production with a focus on 5S, TPM and Kaizen are described. The second chapter is focused on the company TCI, core business, organization structure and analyzes the current status. It’s focused primarily on the process of critical non-manufacturing operations and the changeover cleaning process. The third chapter, following the analytical part consists of the proposed recommendations. The fourth chapter deals with the final evaluation.

Optimization of Production Processes
Adamovič, Michal ; Žilínek, Patrik (referee) ; Videcká, Zdeňka (advisor)
The Bachelo’s Thesis is focused on the analysis of production line of Schaeffler Skalica spol. s r.o. and following proposition of optimalization, using MTM method. In the first part the goals of this work are established. Next part is focused on theoretical basics where I describe the methods that were used to achieve goals mentioned previously. Following part starts with introducing the company and its basic information and proceeds to analysis of current situation. Follow-up section is made of my own solutions for improving the situation. Conclusion of this work is intended for evaluation of the proposed soultions and possibilities of implementation.

A Comparison of migration crises of the European Union in 2015 and 2022 in terms of "push" and "pull" effects - A Comparative case study of migration trends
Fiala, Tomáš ; Kučerová, Irah (advisor) ; Földes, Kristián (referee)
in English The waves of migration from Syria in 2015 and from Ukraine in 2022 significantly affected the number of people who applied for asylum or temporary protection in the EU. In this work, these migration waves are compared through a pre-selected framework of the so- called "neoclassical theory" which operates on the basis of rational decision-making about migration as an "economic" calculation of risks, advantages and disadvantages (so-called "push" and "pull" factors and "intervening obstacles"). Through comparison, the work tries to answer the questions of the similarity of the two migration waves and, through their analysis, at the same time, the question of whether these waves influenced the Migration and Asylum Policy of the EU as such. Despite certain similarities in the political aspects of the comparison, the similarity of the two waves was not confirmed, however, a shift in the creation of the EU migration policy framework after the migration wave in 2015 was also confirmed.

Recruitment through social networks
Koštůr, Adam ; Legnerová, Kateřina (advisor) ; Němec, Otakar (referee)
This bachelor thesis focuses on topical issues of the possible use of social networks for recruitment. In the introduction, the theoretical basis for securing human resources in the organization and activities linked with this topic is described. Furthermore, the theoretical section of the work is focused mainly on the well-known social networks both in the Czech Republic and in the global environment. Also the methods of reaching candidates that can be used through these networks are described. In the practical section of this work, the main focus is given on the survey regarding to the usage of social networks for recruitment. The survey was carried out through questionnaires which were addressed to representatives of companies operating on the Czech market. Besides the description of the research and its methodology, this part includes the results of the survey, which are then examined depending on the companys size and the sector in which the company operates. In the conclusion the main findings of this research are summarized, together with the possibilities of usage of this thesis in practice and the potential direction of further research.
