Proceedings of multidisciplinary conference LASER56
Růžička, Bohdan
Conference LASER56 is a multidisciplinary and intersectoral event where different kind of specialist can meet each other. They come from various environments (private company, university, public research organization etc.). Their common denominators are laser, optics and its applications.\n\n
Technology of monofilamentous fibers based on oxidized hyaluronic acid
Běťák, Jiří ; Mráček, Aleš (referee) ; Burgert, Ladislav (referee) ; Klučáková, Martina (advisor)
Předkládaná dizertační práce se zabývá vývojem technologie výroby nového typu biodegradabilních vláken na bázi oxidované kyseliny hyaluronové. V rámci práce je postupně představován vývoj jednotlivých jednotkových operací výroby, jejichž správné porozumění a schopnost jejich řízení jsou klíčové pro žádaný chod celé vícestupňové technologie. V rámci práce je představen nezbytný vývoj technologického zařízení, průběžně konstruovaného pro účely laboratorního testování a následně až po samotnou linku pro finální výrobu vláken, která byla realizována v roce 2015. V rámci dizertační práce jsou dále navrhovány možnosti dodatečné chemické úpravy vláken s ohledem na zvyšování jejich stability ve vlhkém prostředí. S ohledem na cílené aplikace vláken pro vnitřní chirurgické implantace, jsou v práci vlákna též hodnocena z hlediska jejich materiálové biokomaptibility (toxicity).

Mashrooms and their importance in nutrition.
SOUČKOVÁ, Jana
The thesis is focused on the theme of mushrooms and their importance in nutrition. The theoretical part deals with the chemical composition of higher mushrooms in general and describes their significance for human health. It focuses mainly on the positive effects of mushrooms on the human body. The practical part consists of questionnaires on the subject and their evaluation. The aim of my work was to find out what knowledge about mushrooms people have and how often they consume them.
Solving problems of CD and PMD in optical networks
Motúz, Rastislav ; Šifta, Radim (referee) ; Filka, Miloslav (advisor)
The aim of this bachelor’s thesis is to analyse dispersions which are affecting a high-speed transfer in optical systems. It is focused on chromatic – CD and polarisation mode – PMD dispersion. It is devoted to definitions, limit values, methods of measurements and compensation methods against disturbance to the final quality of transmission. The thesis is divided into the three-chapter long theoretical part and the practical part which contains two chapters. The results of the extensive experimental measurements done by CD/PMD tester – modular platform EXFO FTB-200 are stated in the practical part and partly in the Appendix too. The output of the measurement confirms the theoretical assumptions stated in the theoretical part and thus proves the aim of the thesis to be achieved.
Design of laminate handlebars for mountain bikes
Hanák, Jiří ; Ševeček, Oldřich (referee) ; Polzer, Stanislav (advisor)
This bachelor’s thesis describes design of laminate handlebars for mountain bikes. The first part describes the mechanical properties of composite materials, with the emphasis on fiber composites. The algorithm for acquiring material characteristics of fiber composite by analytical method is presented. In the next part, it is shown how to control the direction of fibers in lam-inate in the finite element calculations and its impact to resulting stresses in the material. The aim of the last part is design geometry model of laminate handlebars for mountain bikes with following stress – strain analysis by FEM and software ANSYS. The analysis is performed for static loading.
Basic characterization of selected samples of animal feeds
Svoboda, Ilona ; Hrstka, Miroslav (referee) ; Vítová, Eva (advisor)
The aim of the diploma thesis was to choose poper parameters for a quick and simple characterization of animal feed, to verify working procedures and to apply these on chosen samples. Within the scope of this work, samples of animal dog feed produced in a private company „Adamkovy tlacenky“ were analyzed. The feed is in the form of brawn, stored in artificial casing; it consists of up to 80% of animal components and up to 20% of vegetable components, while the rest of the weight is the pork gelatine. The feed does not contain preservatives, colourings as well as any other chemically produced additives. For the analysis three formulas were chosen: "Hovězinka", "Kuřátko" and "Srdcovka", the composition of which is protected by the patent. The choice was made to include samples of different composition. The content of raw crude protein, fat, fibre, dry basis, and ash was determined. The obtained values were compared with the standards for feed normally utilized by the feed industry. The results will be used to improve the formulas and to develop new types of feed.
Filament Winding Machine
Dorňák, Michal ; Hampl,, Štěpán (referee) ; Foller, Bronislav (advisor)
The aim of this diploma thesis is the proposal of solution of three-axial winding machine for winding technology of rotary profile. Winding materials are continual springs of carbon, aramid or glass fibre impregnated by resin. The main construction change of the machine compared to commercial available solutions is the use of linear motor as a frame element instead of roller screws or toothed chain. Linear motors have higher dynamics of the movement and they can reach higher speed compared to other solutions, which guarantee increase of the machine productivity. The main importance is put not only on the functionality but also on the low price of this solution. The 3D model of the mechanism is created in the program Inventor 2009.
Study of the properties of concrete with reinforcement, intended for the production of concrete egg-shaped tubes
Šťastný, Antonín ; Hela,, Vlastimil (referee) ; Hubáček, Adam (advisor)
This diploma thesis examines the properties of concrete with reinforcement, designed for the production of a concrete egg-shaped tubes . The stress is put on using various types of fiber reinforcements. Theoretical part is divided into 4 subsections. The topic of the first subsection is a concrete in general. Second subsection deals with various technology of production of concrete pipes. The third subsection is focused on description and summary of basic properties of concrete and reinforced concrete tubes. The last subsection deals with standardized procedures for testing concrete. Experimental part of this thesis is divided into two subsection. First subsection deals with design of a reference sample. Six different samples of a concrete were designed and their rheological properties were tested. Second subsection deals with the additi-on of various types of fiber reinforcement to the reference sample. Eight different admixtures of a concrete were added to the reference sample. Properties of these admixtures were tested in fresh and hardened state.
