This thesis deal with utilization unconventional beam technology (LASER/ water jet) in machine. The aim works is analysis technological possibility method laser and analysis technological possibility method water jet. Further aim of this work is mutual trade-off of the both methods unconventional beam technology and technical economic interpretation.

This diploma thesis deals with two spectroscopic methods - laser induced breakdown spectroscopy and Raman spectroscopy. These methods were used for analysis of alga Trachydiscus minutus, which was cultivated in copper sulfate solutions of various concentrations. First part of this thesis is dedicated to physics and measurements of laser induced breakdown spectroscopy, second part deals with Raman spectroscopy.

Unconventional technologies and their continual development brings along new possibilities in the manufacturing process. The submitted project is focused on solving problems in the procession of sheet metals in the manufacture of special parts of roller and conveyor chains. In the assessment of the technology of components, laser cutting was evaluated as the most optimal technology. With this goal, there was a public tender in terms of the purchase of a new machine designed for the manufacturing operations of the company of RETEZY Vamberk. This company ranks among the most major manufacturers of conveyor, roller and special chains in Europe.

The diploma thesis deals with the use of Laser-Induced Breakdown Spectroscopy (LIBS) for depth profiling and 3D mapping of the zinc-coated steel used in the automotive industry. Before creating depth maps and depth profiles, optimization of the experiment was performed. It was shown that the LIBS technique is suited for making depth profiles and depth maps. The theoretical part deals with the description of the LIBS instrumentation, characteristics of plasma, and assembling of scientific papers which reflect the up to date knowledge about depth profiling and mapping with the use of the LIBS technique. The experimental part describes the optimization of the experiment. Gate delay, the depth and the diameter of craters using the profilometer, the position of the focal plane relative to the sample surface, and selection of spectral lines with the smallest residual signal and small scattering of data were optimized. Depth profiles of zinc, iron, chromium and manganese with the depth map of zinc and iron were made, and also the depth resolution for both elements was calculated.

The diploma thesis deals with problems of laser welding in shielding gases. On the basis of theoretical knowledge in this thesis, was made welding an experiment of 10 samples of steel X5CrNi18-10 in two different shielding gases. Flow of shielding gases has been shown by schlieren method. On the samples of welding joints have been made mechanical tests (tensile test and hardness test). Welded joints were metallography evaluated and structure of them was confirmed by measurements on ferrite meter.

Táto práca sa zaoberá prenosom analytických modelov medzi rôznymi systémami spektroskopie laserom indukovanej plazmy (LIBS) a porovnaním LIBS výsledkov získaných na rôznych systémoch. Instrumentácia LIBS aj spracovanie LIBS spektier sú vysoko flexibilné. Bohužiaľ, kvôli týmto flexibilitám sú výsledky získané na jednom LIBS systéme zriedka priamo porovnateľné s výsledkami získanými na inom systéme. Toto je ďalej komplikované rôznymi, často neznámymi, účinkami algoritmov spracovania LIBS spektier. V dôsledku toho sú modely analýzy spravidla špecifické pre systém (a parametre). Prenos analytických modelov medzi rôznými systémami by viedol k významnému zlepšeniu analytických schopností metódy LIBS a k miernemu zníženiu nákladov v priemyselných aplikáciách LIBS. Práca skúma vplyv rôznych stratégií merania metódou LIBS. Naďalej, práca skúma transformáciu získaných LIBS spektier prostredníctvom spracovávania údajov. Práca sa napokon zaoberá prenosom analytických modelov medzi rôznymi LIBS systémami.

This dissertation deals with a development of a laser welded common rail with a radially attached RPS sensor of pressure. The new concept required by Bosch Diesel s.r.o. Jihlava should be more modifiable and it should be easily integrated with the engine compartment. In this dissertation I suggested a number of concepts that I further analysed, verified in appropriate software, developed, and finally narrowed the selection down to the most suitable solution, which is recommended and justified in the conclusion.

Tato diplomová práce obsahuje komplexní návrh systému aktivního řízení proudu instalovaného na osobním voze Škoda Roomster. Tato práce navazuje na výzkum provedený VUT a TUB na vozidle Volkswagen UP! Návrh lze rozdělit na tři základní části - návrh spoileru, návrh závěsů a návrh vyfukovacího systému. V každé z těchto částí je návrh detailně popsán a potřebná výkresová dokumentace je součástí práce v její příloze. Pro potřeby návrhu vyfukovacího systému bylo provedeno jeho testování. Výsledky testu jsou v této části uvedeny. Práce také obsahuje komplexní popis sestavení celého systému a jeho instalace na automobil.

This thesis deals with the design and manufacturing of custom-made immobilization orthosis for the upper limb. Emphasis is put on the digitization of the approach and integration of additive manufacturing in the workflow of splint production. The solution proposes automatic model construction based on a 3D scan. Such a model is further parametrized in order to provide splinting practitioners with customization abilities. Particular attention is paid to the changes of limb volume due to swell, where the use of auxetic structures is suggested.
