The new concept of maintenance and operation of manufacturing technologies
Klus, Jakub ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis deals with a new concept of maintenance and operation of production technologies, where spare parts are manufactured using rapid prototyping methods. The options are compared with currently used methods. Furthermore, methodological recommendations are written on how to proceed with the application. The aim of the work is to evaluate the concept and confirm the theoretical assumptions on a case study.

Comparison of certified and lowcost material for stereolithography 3D print
Sobota, Matej ; Zatočilová, Aneta (referee) ; Koutecký, Tomáš (advisor)
The aim of the bachelor’s thesis is to define basic quality parameters and compare material impact on quality of printed products. This is a comparison certified material with low-cost material using SLA-DLP method of 3D printing to reduce production costs. The thesis is focused on the comparison of two different materials based on the results of tensile and hardness tests. The effect of the color of photopolymer on material properties is also observed.

Project of Client-based VPN Remote Access Solution for the worldwide Retail Business Company in the region of Central Europe
Ondrák, Richard ; Havlín, Petr (referee) ; Kříž, Jiří (advisor)
The aim of this Thesis is to project and describe new Client-based Remote Access Solution for the Tesco Stores retail company in the region of Central Europe. Based on facts that the all present Tesco’s Remote Access Systems have not any longer met the increasing requirements and needs of corporate users and suppliers it is clear that the main scope is to find and implement such Solution that will meet and exceed all requirements. The main Project Aspects are to be the ease of use, security of the solution, unexacting administration of the system and user groups, and one unified Solution for the all Countries from the region of Central Europe that is suitably integrated in the Tesco IT infrastructure.

The influence of the parameters of stereolithographic 3D printing on the printing time
Kůst, Martin ; Škaroupka, David (referee) ; Zatočilová, Aneta (advisor)
This paper deals with stereolithographic 3D printing (SLA). It describes both upper and lower lighting design and shows the differences between laser light and DLP (Digital Light Processing) projector. Another part is to find the dependence between the time of exposure and the thickness of the layer also known as material profile on the DETAX, gray. So another work and further experiments can be done using this material. These experiments are performed on Way2production's SolFlex650 SLA printer. For ease of use with this printer, parameters affecting print time have been identified and a model is then found to calculate the total print time.

Use of 3D printers for prototyping in a network environment
Svoboda, Daniel ; Jan,, Suchý (referee) ; Sedlák, Petr (advisor)
The bachelor thesis deals with the use of 3D printing in the process of prototyping and production. It compares 3D printing with classic production methods. Describes various 3D printing methods and various printer designs. It also compares open systems with systems that are locked. Describes the procedure by which it is possible to create prototypes and then final products.

Backup power supply with solar panel charging
Křepela, Pavel ; Götthans, Tomáš (referee) ; Kubíček, Michal (advisor)
This project aims to create a backup power source with solar charging for small mobile devices (through USB connector). The charger should store power in a battery that is charged either from external power source or the solar panel. In the introduction, the work deals with the theory of solar cells and batteries. Furthermore, it described the selection of suitable components and design diagram.

Application for early detection of transmission parameters degradation of microwave units
Bubniak, Milan ; Benedikt, Jan (referee) ; Musil, Petr (advisor)
Radio equipment of microwave links operating in an outdoor environment under the influence of weather conditions is at risk of a link failure or device defect occurrence, as well as their indoor units. This bachelor thesis aims to present the creation of a~network monitoring application capable of timely detection of potential failures, based on analyzing trends in monitored device parameters. The theory section deals with basic characteristics of microwave links and the structure of Simple Network Management Protocol. The practical section describes an application design, including core architecture, as well as a graphical user interface. Several failure detection methods are designed and described. In the next section, practice monitoring results are presended. Furthermore, network traffic and data storage requirements are measured. The conclusion summarizes the results of the application development and outlines it's future with new possible features.

Information System Assessment and Proposal for ICT Modification
Lapuníková, Eva ; PhD, Lucie Ciencialová, (referee) ; Koch, Miloš (advisor)
Assessing the company’s information system, this thesis deals with an analysis and proposal to changes, that lead to improvement of a company‘s current situation. In the introductory part there is a theoretic explanation regarding the issue of information systems and also a description of some analytical tools. In the next part there is an acquaintance with a company and an analysis of a current state of IS/ICT using several methods. The results of this analytical part then serve as proposal to changes including benefits evaluation, which the company can use and therefore improve its current position on the market.
