Modeling and fault detection of electric power system
Kluz, Jan ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
Thesis focuses on the topic of fault detection of power systems. First part presents a comprehensive review of area of reactive, preventive and predictive maintenace of power systems based on physical or AI–driven models. Important part is design and subsequent assembly of an experimental testing device. This device incorporates four faults: heightened contact resistance, low contact area, parallel load imbalance and sparking. Device contains precise current and linear Hall sensors. The device has successfully been assembled and tested with positive results. A lumped parameter thermal networks has been created on this experimental device and results were verified with measured data. Thesis also contains statistical analysis of voltage and current signals, that were captured during spark discharges with 10 – 90 voltage supply.

Modern approaches to maintenance in engineering practice
Vašíček, Martin ; Hájková, Alena (referee) ; Hammer, Miloš (advisor)
The bachelor thesis is focused on maintenance. The first part presents the current maintenance standard entitled "Maintenance-Maintenance Terminology" and the older standard with the same name, which was replaced by the current standard. The work describes the types of maintenance according to each of these standards and compares them with each other. In the second part, modern approaches to maintenance in engineering practice are presented. The third part is focused on one of these modern approaches, namely TPM. The fourth part is focused on the implementation of TMP in two companies.

Modeling and simulation of PLC-BPL communication of smart metering in Network Simulator 3
Baranyk, Matěj ; Rusz, Martin (referee) ; Benešl, Lukáš (advisor)
n recent years BPL technology is becoming more used. Despite the technology not needing any additional cable installation it's important to make sure that using the technology itself makes sense or what the needed requirements will be. Due to this reason we opt to simulate real life scenarios and compare them with outputs from network simulator ns-3. This way we're able to recognize the usefulness of our efforts even before we make any plans to instal anything, which saves time and money. Furthermore we can use the same simulator for diagnostics of already installed BPL routes. Furthermore a laboratory measurement shall be conducted in order to increase dataset sizes and to have more data that can be compared with simulation outputs.

Preparation of training materials for high voltage switchgears
Nosek, Jan ; Kozel, Tomáš (referee) ; Lázničková, Ilona (advisor)
This Bachelor thesis documents the creation of training materials for high voltage switchgear. Most of the work is devoted to introduction of products of ABB company, which the training materials are developed for. The main emphasis was on introduction of the UniGear ZS1 switchgear, which the main product of ABB's high voltage switchgear domain is. The last chapter is devoted to the analysis of the different levels of training materials.

Augmented Reality for Training and Execution of Airplane Maintenance
Košík, Michal ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
This thesis deals wtih augmented reality applied to aircraft maintenance which is widely explored here. Furthermore, a reseach is done on the previous work done in this field. A video data-set is acquired from LET - a manufacturer of LET L-410 aircraft and an application is created in order to test possibilities of using augmented reality in aircraft maintenance. The result and proposals of the future work can be found in this thesis as well

Current trends in the airline industry
Štourač, Filip ; Sedláček, Pavel (referee) ; Rujbrová, Šárka (advisor)
Cílem této bakalářské práce je popsat současné trendy v leteckém průmyslu a nastínit předpokládaný budoucí vývoj v této oblasti. Úvod práce začíná stručným shrnutím historie letectví, které je následováno krátkým popisem současného leteckého průmyslu. Další kapitola se zabývá ekologickými technologiemi a udržitelností letectví se zaměřením na 3D tisk, ekologické letecké palivo a 2 rozdílné typy proudového motoru: LEAP od společnosti CFM a Geared turbofan od Pratt&Whitney. Následuje třetí kapitolou s přehledem bezpečnostních technologií ve které je popsán systém GPWS a senzory snímající kontaminaci ranveje. Další kapitola se pak zabývá aktuálními změnami v technologiích údržby, způsobenými rostoucím trendem Internetu věcí. Poslední kapitola čtenáři odhaluje předpokládaný budoucí vývoj leteckého průmyslu.
