Energy Harvesting for Industry 4.0 Applications
Gajdošík, Róbert ; Šimek, Václav (referee) ; Smrž, Pavel (advisor)
Cieľom tejto práce je demoštrácia možností využitia energy harvestingu v priemysle 4.0, so zameraním na prototyp samonapájacieho vibračného senzoru. Vrámci práce bol vykonaný výskum techník pre zhromažďovanie a spracovanie dát ako aj výskum ohľadom senzorového vybavenie budúceho prototypu. V ďalšom kroku bol vykonaný výskum a získaný prehľad ohľadom energy harvesterov, metód presunu a manipulácie vyťaženej elektrickej energie, a spôsobu jej uchovania. Ďalej bol vybraný vhodný mikroprocesor s vhodnou výbavou ohľadom vstupu a výstupu napájania, energie a konektivity. Nakoniec implementácie boli vyriešené rozhrania medzi jednotlivými komponentami prototypu. Po vyhodnotení ďalšieho postupu bolo rozhodnuté vyvinúť software pre plánované rozhrania medzi senzorom a procesorom, ako aj spracovávanie dát za použitia vzorkovania a rekonštrukcie analógového signálu za použitia analógovo-digitálneho meniča. Ďalej bola vyvinutá jednoduchá časť software pre detekciu anomálií v očakávaných frekvenčných pásmach daného objektu, a otestovaný jednoduchý kód pre využite subsystému BLE. Nakoniec tejto časti projektu boli preskúmané možnosti vylepšenia účinnosti využitia energie použitej pre napájanie mikroprocesora. V poslednom kroku práce boli otestované všetky komponenty navrhnutého prototypu. V prvej časti bola otestovaná funkcionalita komponentov bez integrácie s ostatnými časťami systému. Bola testovaná presnosť vibračného senzoru, funkcionalita harvesteru, a otestované jednotlivé subsystémy mikroprocesoru. V druhej časti testovania boli testované interakcie jednotlivých komponentov, napríklad rozhranie medzi mikroprocesorom a vibračným senzorom, a testovanie korektnosti softvérových metód pre vypočítanie frekvencie monitorovaného objektu. V poslednom kroku testovania boli otestované množstvá enegie vyťažené piezoelektrickým efektom a porovnané s experimentálne overeným odberom energie kompletného obvodu. Následne boli tieto informácie využité k aproximácií ceny prototypu a jeho realizovateľnosti v praktickom priemyselnom prostredí. Výsledkom práce je funčný prototyp obvodu samonapájacieho vibračného senzoru a teoretický návrh efektívnejšej verzie založenej na experimentálnych metódach prenosu energie medzi harvesterom a úložistom energie, ako aj aproximácia jednotkovej ceny obvodu a vyhodnotenia jeho použiteľnosti v modernom priemysle.

Multifunctional modular FDM 3D printer
Indra, Zdeněk ; Vyroubal, Petr (referee) ; Jaššo, Kamil (advisor)
This work deals with problems of 3D printers, their types according to function principle and their design. In addition to print materials, FDM printers chapter includes the types of motion systems available for FDM 3D printing, and the possibility of converting 3D printers to other CNC devices is discussed. This theory is then evaluated and the most suitable parts are used to build modular CNC machine wich is then tested in configuration of FDM 3D printer.

Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno
Sudolský, Filip ; Hrabec, Josef (referee) ; Šindlar, Jiljí (advisor)
The main subject of the diploma project was to create architecture study for new building of a Gallery for sport aircrafts and their traditions and other equipment that cooperate with this topic. The Gallery is designed in Brno´s Medlanky municipality and it is incorporated on current local sport airport. This project was preceded by studio project on the same area, which included reconstruction and development of this airport area. In this diploma project I was trying to continue with this development and establish a design which would react to my earlier design. The site has a sloped character and it separated from a dense city area. Starting point for the design was to gently touch the landscape and also trying to find certain references directly in the closest surrounding. From the views to surrounding was created the idea to preserve the horizontal lines and with a landscape and constructions demands was created the main idea to continue with the landscape over the spatial structure. The need to cover large-scale exhibit items like aircrafts and other items from this topic led to a starting point of my design. The structure is formed as a spatial truss structure and dominates the exhibition space. Building is connected by program and structure to services and other areas like conference hall, coffee, study room, work room and administration. As a one building it teems mainly from arrival at the airport area when the roofing is an organic, monolithic surface disappearing in surrounding. But gallery itself emerges from the ground and opens towards the aircraft take off and departure area where it is also direction of a main view to the surrounding. The building is also unique for its entering, such as the main entrance through narrow staircase gap in the roof. This entrance should evoke to people an aircraft landing, where while descent plane dive in to the clouds and appear underneath above a whole new landscape. Thus a person sore in to the roof surface a

Prototype part and made by method rapid prototyping
Kočárek, Karel ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is dealing with prototype stage during development of reduction part for gas flow control, which is positioned in gas boiler downstream of the valve. Thesis is focused on additive manufacturing. Basic technologies, their attributes and procedures which are necessary to be followed are described here. Practical part is composed of 3D model creation in CAD software, export of model to STL format and its inspection for compactness. After that 3D model is sent to printer and functional components are made, that can be used for application verification and for detection of possible design deficiencies before the mold assembly is made.
