Value stream analysis and improvement
Malec, Tomáš ; Hégr, Ondřej (referee) ; Novotný, Radovan (advisor)
This thesis deals with the general analysis and value stream improvement. The theoretical part describes the difference between functional and procedural model of company management, mutual benefits and disadvantages of these systems. The thesis deals with the mapping process, subdivision maps and methodology of process maps creation. The work also includes software analysis for process mapping. Next section contains search of selected optimization tools and methods to improve production flow and description of the principles of controlled documentation. In the practical part is realized mapping process of bachelor studies at FEKT and map of production process at ABB switchgear.

Design of the high frequency tunable oscillators
Malec, Tomáš ; Vochyán, Josef (referee) ; Petržela, Jiří (advisor)
This paper deals with the simplest structure capable of generate harmonic signals of high frequency and stable amplitude. As essential elements of these oscillators have been used active blocks known as diamond transistors. The proposal was given to minimize the number of components and smooth electronic retuning. These proposed districts have been theoretically analyzed by the program PSpice and practically verified. The document contains the results of these reviews and readings focusing on the total harmonic distortion, frequency agility and range of phase noise.
