Use of acoustic emission technology to assess corrosion of materials
Procházka, Adam ; Vašíková, Simona (referee) ; Binar, Tomáš (advisor)
The thesis deals with the description of acoustic emission as a non-destructive testing method and its use in the detection of material corrosion. The first part describes the theoretical principles dealing with the explanation of what acoustic emission is, how it is defined according to the standard, what are the types of acoustic emission and how it is tested. It then discusses corrosion, the types of corrosive environments where corrosion occurs and the types of corrosion tests. It also describes where acoustic emission has been used in practice and what experiments it has been used for in terms of material monitoring. The next part of the paper describes the experiment of acoustic emission measurement on grey cast iron samples, describes the fabrication of the samples, the use of corrosion protectors, and the placement of the samples in a condensation chamber for continuous testing. The last part is the evaluation of the results .

Determination of anodizing parameters for surface properties of aluminum alloys
Paclík, Eduard ; Vaverka, Ondřej (referee) ; Košťál, David (advisor)
The bachelor's thesis deals with the determination of basic parameters for anodizing aluminum alloys. The introductory passages include an overview of aluminum alloys suitable for anodization, theoretical and practical assumptions of anodic oxidation. The main experimental part discusses the laboratory anodic oxidation of aluminum alloy samples under different parameters of surface roughness, current density, and voltage. Anodically oxidized samples were tested on special UMT tribometer and Contour GT-X profilometer devices for friction coefficient measurement and surface inspection. The measurement results were used to determine the dependence between surface roughness of aluminum alloys and the quality of the anodized layer, the dependence between current density of the anodic process and the quality of the anodized layer, and the dependence between voltage and the quality of the anodized layer. The problem was solved within the possibilities of FSI laboratory conditions. The thesis serves as a basic orientation in this field.

Compensation of distortions caused by movements of objects scanned by a line scan camera
Szabó, Michal ; Shehadeh, Mhd Ali (referee) ; Škrabánek, Pavel (advisor)
Tato diplomová práce se zaměřuje na kompenzaci zkreslení v datech ještěrek získaných pomocí řádkové skenovací kamery (LSC), která snímá ultrafialové (UV) vlnové délky. Dýchací pohyby během skenování způsobují zkreslení šířky trupu ještěrky, což ovlivňuje konečný snímek LSC. Práce navrhuje metody zpracování obrazu pro úpravu těchto zkreslení, včetně extrakce kontur, interpolace a vyhodnocení pomocí referenčního snímku. Metodika má za cíl minimalizovat rozdíl mezi upraveným LSC snímkem a referenčním snímkem.

Industrial data logger
Matula, Ondřej ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
This thesis deals with the design of an ON-LINE diagnostic system named as "industrial data concentrator". The thesis looks at the design itself in a comprehensive way and brings together parts such as defining useful diagnostic variables, a competitive comparison with already available commercial products and the actual design of the industrial data concentrator both in terms of hardware and software.

Universal audio interface for autonomous use
Trojak, Ondřej ; Šťáva, Martin (referee) ; Levek, Vladimír (advisor)
This text analyses the current situation within the audio signal work field and the appropriate ways of connecting electronic networks for processing blocks. The thesis deals with circuit design, firmware programming and physical realization of a subsequently measured autonomous battery-powered interface which provides volume control of input signals and conversion of different types of connectors and signal lines, consuming low power and adding low noise. The device is also equipped with a phantom power supply for condenser microphones. The control consists of a set of buttons, a rotary encoder and a display unit.

Production of extracellular polysaccharides by extremophilic prokaryotes
Bystrická, Klaudia ; Smilek, Jiří (referee) ; Obruča, Stanislav (advisor)
Predložená diplomová práca sa zaoberá štúdiom biotechnologickej produkcie extracelulárnych polysacharidov (EPS) vybraných termofilných a halofilných mikroorganizmov. Po primárnom screeningu vybraných kultúr bola experimentálna časť tejto práce ďalej venovaná halofilnému archea Haloferax mediterranei. Cieľom tejto práce bola produkcia a charakterizácia polymérov a posúdenie biotechnologického potenciálu použitých extremofilných kultúr ako producentov EPS. Počas kultivácie H. mediterranei boli použité 3 základné média, ktoré boli následne optimalizované v prospech produkcie EPS. Získané precipitáty boli podrobené analýze pomocou GPC, FTIR a UHPLC-UV-ESI-MS/MS, na základe čoho bolo možné bližšie charakterizovať získaný produkt. Tieto experimenty dokázali, že so stúpajúcou koncentráciou NaCl v médiu, klesá výťažok polysacharidov a ich produkciu nepodporujú ani vysoké koncentrácie MgSO4 a KCl v médiu. Hlavnou komponentou polysacharidov vyprodukovaných H. mediterranei, je manóza, no v závislosti od použitého média môže obsahovať aj glukózu, galaktózu, ribózu alebo N-acetylglukosamin.
