Analysis of the mechanical properties of plastic materials for 3D printing
Jelínek, Jan ; Bártková, Denisa (referee) ; Koutný, Daniel (advisor)
This work will solve the mechanical properties of materials used in the FDM technology.Thetensile and flexuralmechanical properties depending on theprintingparameterswillbetested. Fortestingare used three types of sampleswithdifferentrastersforeachof the tests. The first type of raster is characterized by a fundamentalparameter, whichisoffered by themanufacturer. The second type of raster is characterized by a high number of thin-fiber material and a higherconcentrationof air gaps. The third type of rasterischaracterized by minimalnumberof air gaps and a minimum number of thick-fibers in thecross-sectionalofsample. These typesofsamples will be tested on selected materials. The results of individual tests willbecomparedamongselectedmaterials and types of samples. The aim of this work is to show the dependence of mechanical properties on the type ofprintingstrategy.

Proposals for Improving Economic Performance
Červenka, Vlastislav ; Jelínek, Jan (referee) ; Luňáček, Jiří (advisor)
This bachelor’s thesis aims at evaluation and improvement of the performance of the company Zlínprofi, s.r.o. using both financial and nonfinancial analysis. This work is divided into theoretical part and practical part. The theoretical part describes methods which the subsequent analysis uses. After that the company is introduced and its financial and strategic analysis is conducted. The results are then compared with the recommended values and competing company. In the conclusion the overall situation is evaluated and based on these resulting facts suggestions for improving the financial performance of the company are proposed.

Nonlinear buckling analysis of a flue gas pipe
Jelínek, Jan ; Vincour, Dušan (referee) ; Létal, Tomáš (advisor)
This thesis deals with the nonlinear analysis of stability loss of flue gas pipe. This pipe is a part of desulphurization line. The thesis describes the creating of a simplified FEM model. It also describes the setting of the boundary conditions of the model for few loading cases. These cases differ by preference for one of the load as dominant. There are proposed several variants of stiffening by light ring stiffener. The work is finished by comparing the resistance to the stability loss of the reinforced variants and unreinforced model of flue gas pipe.

Kidsgarden
Jelínek, Jan ; Blažková, Vendula (referee) ; Daněk, Lukáš (advisor)
The goal of this thesis is to create a design documentation for a kindergarten. This building is situated in the city called Brtnice – more specifically in its newly established location Nová Čtvrť. The kindergarten has two floors. Walls of the first one are partly sunken under the surface level. Each floor is divided into an operating section and part for a preschool education. The building has a foundation made of plain concrete bands, built from an aerated concrete and has a flat roof. Following building project puts an emphasis on a spatial and architectonical layout, energy savings and overall safety.

Internationalization of Company EPRIN, spol. s r. o. on Slovak Market
Bártek, Ondřej ; Jelínek, Jan (referee) ; Zich, Robert (advisor)
This diploma thesis is focused on the possible forms of internationalization. The aim is to propose possible strategies of internationalization of EPRIN, spol. s r. o. company on Slovak market. Theoretical resources deal with the explanation of different approaches to internationalization and possible forms of entry into foreign markets. After the theoretical resources follow analysis of the current state, where company is described, are made analyses and is summarized its competitiveness. On the base of finding is suggested a possible strategy to reach foreign market, which should bring new customers, to help raise the profile and reach out to other markets.

Between the cross and the cup. The press of the Czechoslovak People's Party at the time of the Marmaggi affair
Jelínek, Jan ; Randák, Jan (advisor) ; Čechurová, Jana (referee)
Presented thesis deals with content of press connected to Czechoslovak People's Party by the time of so called Marmaggi affair and the campaign in 1925 elections to the National assembly. It stands on a premise, that followed texts mirrored positions of czech political catholics, whose main representative was the People's Party. Party leadership set from a start course of conciliation and loyalty toward Czechoslovakia. This direction had gone difficult by several factors, among them anti-catholic wave following formation of new state and first months of its existence. Even after it's decline anti-clerical and anti-catholic tendencies didn't disappear, as we can find their bearers among the leading figures of the republic, including the president Tomáš Garrigue Masaryk. This research raises the question of the process of the political-catholic press receiving policy of the party leadership policy of loyalty toward state, in time of rupture between the republic and catholic church, which strenghtened the tension between loyalty toward the state and the patriotism on one side and catholicism on the other. How did the catholic journals comment the course of the party? Did they try evaluate, defend or criticise? Did they suggest an alternative to it? Was expressed any attitude towards the state even by...

Working conditions of employees in the selected home for the elderly
Jelínek, Jan ; Dobiášová, Karolína (advisor) ; Tůmová, Kateřina (referee)
This bachelor's thesis investigates working environment of employees of one particular retirement home. The jobs being looked at are as follows - social worker, activation worker and certified nursing assistant. These spots are divided into two groups, the more professional and creative one and the social one. I define the working environments through qualitative semi-structured interviews. To discover the environment in question, it is important to describe the content of the job and the tasks that one doing it is obliged to fulfil, the well-being of the ones doing it and the personal relationships in the workplace. I discover the characteristics of the jobs taking internal regulations, legal definition of the job and interviews into account. Using the workplace wellbeing theory, which consists of five basic dimensions, I describe the working conditions of the jobs in question. Those dimensions are used to examine the aspects that have major influence on the workers' wellbeing. Those are the ones that concern the employees' career ambitions, physical demands on them and the influence they have on their physical state, how the job is socially, how much the workers make for a living and how they fit in their communities. I will study personal ties between employees through the theory of positive...

Suitable methods of data prepration for mutistream compression
Jelínek, Jan ; Žemlička, Michal (advisor) ; Falt, Zbyněk (referee)
This work focuses on compression algorithm called multistream compression. We have tried to improve this algorithm to be competitive with other commonly used compression algorithms. We have also tried to combine it with well-known transformations like BWT or MTF to efficiently handle text files. Another part of the research was compose characters into bigger parts and transform the result by multistream compression. We have tried blocks of constant length like bigrams and blocks of variable length like syllables or words. Last experiments was with small changes of MSC algorithm and compare them with the original algorithm.
