Web Application for Intuitive Composition of Text Filters
Sadílek, Jakub ; Kolář, Martin (referee) ; Herout, Adam (advisor)
The aim of this thesis is to provide intuitive and easy to use tool for advanced text filtration with the option of easy prototyping and tuning, without the necessity to know programming techniques. The basic principle is the choice of text tools and their inserting into the sequence, so called pipeline, which is typical for shell, from which the application draws inspiration. Tools can be also additionally edited or swapped. The application is aimed primarily at users unfamiliar with this principle or at programmers, for whom it is time-efficient to have their text modified this way and afterwards generate equivalent shell expression. Another way of tuning is realized using so called breakpoints, through which it is easy to quickly focus on chosen lines of the text. This way, the application offers functionality in two separated modes, between which the users can switch anytime according to their needs.

Fabrication of well defined nanoporous structures with application in membrane sensing
Fabianová, Kateřina ; Édes, Zoltán (referee) ; Sadílek, Jakub (advisor)
Theme of this bachelor thesis is focused on preparation of the metal nanomenhir structures situated in highly oriented matrix of silicon nitride nanopores based plasmonic biosensor. Porous structures were prepared by reactive ion etching of silicon nitride film using electron beam lithography prepared temporary mask as a template. Deposition of metals was handled by evaporation and magnetron sputtering and results was compared. Finally, this work assumes reached results including successful approach of sensor preparation without contamination of surrounding surface by heavy metal ions.

Plasma-enhanced chemical vapor deposition using TVS/Ar and TVS/O2 mixtures
Sadílek, Jakub ; Salyk, Ota (referee) ; Čech, Vladimír (advisor)
Tato studie je zaměřena na základní výzkum přípravy a-SiC:H a a-SiCO:H slitin plazmových polymerů pomocí metody plazmochemické depozice z plynné fáze (PE-CVD). Tyto slitiny byly připravovány depozicí z monomeru tetravinylsilanu (TVS) a jeho směsí s kyslíkem a argonem při různých efektivních výkonech pulzního plazmatu. Připravené tenké vrstvy byly za účelem získání závislostí optických, mechanických a chemických vlastností na depozičních podmínkách zkoumány pomocí metod spektros-kopické elipsometrie (ELL), nanoindentace (NI), fotoelektronové spektrometrie (XPS) a Fourierovy transformované infračervené spektrometrie

Modern Inorganic Building Materials Free of Portland Cement
Sadílek, Jakub ; Opravil, Tomáš (referee) ; Zmrzlý, Martin (advisor)
This bachelor’s thesis is focused on properties of modern construction inorganic ma-terials – geopolymeric concretes. In introductional part of work it is described basic theoretical background, as properties of binders, principles of setting and hardening. For preparation of geopolymer matrix was used secondary or waste materials of energetic and metallurgical industry – fly ashes and slags. In laboratory were prepared four com-positions of geopolymeric concretes combined from geopolymeric matrix with constant compostition and variable composition of aggregates. As aggregates these materials were used: three fractions of quartz sand, steel furnace slag and in one composition also crystals of mineral wollastonit. It was discovered that the use of steel furnace slag as aggregate in geopolymeric concrete has positive influence mainly to compressive strength, but the addition of wollastonite mineral do not evocate expectable increase of mechanical properties of samples.
