Small axial magnetic flux motor for pump
Lacina, David ; Ondrůšek, Čestmír (referee) ; Huzlík, Rostislav (advisor)
This thesis aims to design a motor with axial magnetic flux, which could be used as a direct propeller of heart replacement pump. It is divided into several parts, first of which deals with describing possible axial motors construction design. Next follows up the description of possible motor designs, from which the non-ferrous one was chosen. After that, an analytic calculation of motor’s properties is conducted. Calculated parameters are thereafter verified by software tools using finite element method. Finally, the whole motor was manufactured and had its parameters tested and verified.

Axial magnetic flux electric machine
Lacina, David ; Bárta, Jan (referee) ; Huzlík, Rostislav (advisor)
This thesis deals with axial flux permanent magnet machines. It is divided into four parts. The first one describes how axial-flux machines can be categorized. It also explains basic construction designs and their properties. Second part focuses on designing axial-flux machine. The analytical calculation of the machine is then checked using finite element method in software Ansys Maxwell. In the last part the calculations are also checked by measurement of an actual axial flux machine. In the summary is a comparison of analytical calculation, simulation and measuring.

Návrh zavedení systému managementu jakosti
Lacina, David
The thesis deals with the proposal to introduce a quality management system. In the first part of the thesis is done a literature search in the field of quality management systems (QMS). In the second part is described possibility of implementation of QMS in company DIEFFENBACHER. In the third part is done SWOT analysis for company DIEFFENBACHER. There are defined strengths, weaknesses, opportunities and threats. Based on this analysis is elaborated a strategy. In the fourth part is described process of implementation of QMS. In the last part of the thesis is a feedback and overall efficiency of implementation of the entire QMS for company DIEFFENBACHER DCZ.

Analysis, testing and proposal to improve selected business applications
Lacina, David ; Benáčanová, Helena (advisor) ; Štryncl, Luboš (referee)
Thesis is about analysis of two applications, which is used or will be used in selected company. First of these applications is E-PROD. By the application is solved possibility of automate ability of data entry. These data are used by the application for counting of productivity. The second application is ABC TOOL. This application is not used in company, because it isn't testing its functionality on Czech platform. The application is in the thesis tested and analyzed. Based on tests it will be decided whether the application is applicable for Czech branch. The thesis also deals with proposals about optimization of using applications and with suggestions for their modifications and extension. Outputs should be information about how to improve the software support of selected process.

Zajištění kvality při zavádění nového výrobku do sériové výroby
Lacina, David
The bachelor thesis deals with the retrieval process, introducing a new product into production. In the case of this study, I chose a plastic lever to open the hood on a car. The starting material for the production was selected GF30 Polyamide 6.6. The annual estimated production run will be 250,000 copies. Plastic lever will be produced on the injection press DEMAG 100/420-310.

Information and communication channels that are used by students of University of Economics
Lacina, David ; Benáčanová, Helena (advisor) ; Vondra, Zdeněk (referee)
This written work is about the information and communication channels that are used by students of University of Economics. The word "channels" can be replaced by the word "sources". Primary goal is to identify important information and communication sources and then describe them, evaluate them and find their deficiencies. Secondary goal is to examine the sources that are designed for students of the first year, for example the day of the open doors or the familiarization tour. Work is divided into two parts according to type of the sources. The aim of work is to find a solution to deal with the revealed shortcomings and introduce recommendation how to repair overall conception of giving the information to the first year students and how to repair channels that are used by all the students. For evaluation of the channel there was made a questionnaire which was send to the students of University of Economics.
