Ablation chamber for a combination of LIBS and LA-ICP-MS techniques
Sovadina, Petr ; Kuchynka, Michaela (referee) ; Novotný, Jan (advisor)
Laser-induced breakdown spectroscopy (LIBS) and laser ablation inductively coupled plasma mass spectroscopy (LA-ICP-MS) are spectroscopic techniques that use a pulsed laser to ablate the material in their analysis. Although LA-ICP-MS can reach a much lower detection limit than LIBS, it is not able to detect elements of organic compounds, halogens, and noble gases. By combining these two spectroscopic techniques, it is possible to overcome these shortcomings, to analyze all elements with LIBS, and also to analyze with a lower detection limit with LA-ICP-MS. To perform this combination of spectroscopic techniques, it was necessary to design an ablation chamber that would simultaneously support both LIBS and LA-ICP-MS measurements. The design of the ablation chamber consists of the mechanical design, the simulation of the gas flow inside the chamber, and finally its fabrication and assembly.

VUV spectrometer for vacuum interaction chamber
Drobil, Tomáš ; Šerý, Mojmír (referee) ; Novotný, Jan (advisor)
This thesis deals with the design of a VUV spectrometer for the Laser-induced breakdown spectroscopy (LIBS) method. A prototype using commercially available components was designed and tested. In addition to the actual development of the optical and mechanical design and the selection of the detector, a thorough research of elements emitting in the VUV region was carried out.

Energy balance in wastewater treatment plants
Novotný, Jan ; Raclavský, Jaroslav (referee) ; Hluštík, Petr (advisor)
This masters thesis is dealing with energetic evaluation of selected municipal WWTP – WWTP Polička. First chapter, introduction explains basic terms and goals of thesis. Second chapter explains energy audit, energy audit process its scope and contents. Third chapter deals with assesing life cycle using LCA (life cycle assesment). Fourth chapter deal with energy consumption at WWTP in Czech Republic as well as in the world. Fifth chapter describes technology of WWTP Polička and its fundamental objects. Sixth chapter is assesment of WWTP Polička from hydraulic point of view and assesment of selected machinery. Further there is summation of capital and operational costs followed by capital investment return.

Testing of the experimental model of the distribution system 22 kV
Musil, Milan ; Topolánek, David (referee) ; Novotný, Jan (advisor)
The aim of this project is practical verification and finding of the main parameters of model elements (lines, transformer, suppresion coil). This supresion is needed for eventual model testing of faults that might occur in the configured distribution network. The measurement was done using the equivalent model and computing zero-sequence impedance or admittance and their parts. Also it was necessary to find out the parameters of transformer, which consisted of a force measurement. Another part of thesis deals with the proposal of the new model elements. The most important of them is the model of switch, witch needed to protect model and the surroundings during nonstandart network conditions (faults).

The proposal of a special measuring device to check the chamfer
Novotný, Jan ; Zahálka, Jiří (referee) ; Pernikář, Jiří (advisor)
This diploma thesis consist of basic overview of contact and non-contact measuring methods used at present days across industrial Applications. On the base of given specification for designing of measuring station for measuring chamfer of rotary components The choice and evaluation of theoretical applicability for our application is performed. In the practical part of this diploma thesis The applicability is verified. Performance of these a few exemplary measuring shows possible way of design of constructional solution. All this in a close cooperation with company MESING.

Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.

Influence of electricity generation on the environment
Žák, Jiří ; Novotný, Jan (referee) ; Matoušek, Antonín (advisor)
The concern of this Bachelor Thesis is current structure of electric energy sources in Czech Republic and their influence on the environment. The theoretical part maps the current state of energetics, structure of sources, consumption and installable output in ES CR. In the thesis, there is shown evolution of balance of electricity since 1988 and netto production of electricity in CR. There is also decribed export and import of electricity in the year 2008 and determination of the influence of different energetic equipments on the environment. The practical part deals with the emission of individual types of power stations, their manufacturing, calculation and possibilities of decreasing amount of carbon dioxide emission from the electric energy manufactories. Next point considers predicted development of equipments in relation to the environment. In the end, there is the overall evaluation of achieved information and results with influence on the environment.
