Improving Efficiency Concept of Machining Technology of Chimney Liner
Kubů, Marek ; Kyncl, Jiří (referee) ; Sedlák, Josef (advisor)
Diploma thesis contains introduction of a company P-D Refractories CZ a. s., where the manufacture of ceramic chimney liners is. Followed by a description and analysis of the product in the entire production cycle, material and product spectrum. Based on the results of current production is created proposal to streamline the machining technology with a view to increase productivity and reduce defective products, which means determine the material of a tool and the method of machining. The work is finished by technical-economic assessment, where the summary and recommendation of the proposed solution are.

Slovene National Theatre in Ljubljana
Pivoňková, Dagmara ; Bajger, Oldřich (referee) ; Kynčl, Jakub (advisor)
The plot for a new theater is in historic centre of Ljubljana and it is defined by block of existing buildings. I designed theatre with 3 variable scenes – one for 500 spectators, two for 100 people each. In addition i propose the theatre square – big exterior arena. The proposed building is an ending of urbanictic axe, that is why it has shape of monumental gate. The gate is oriented to the south, so i covered the fasade with huge fotovoltaic sreen, that is collecting electric energy during the day and shining this energy out during the night as a big city culture screen..

Multipurpose Town House on Křížová Street, Brno
Souček, Michal ; Kynčl, Jakub (referee) ; Ruller, Ivan (advisor)
The aim of this Diploma Thesis was the design of multipurpose town house located on Křížová Street, Brno with the significant housing part, but also with areas for administration offices and commercial use. The project focuses on new attempt and concept of inner part of the block, as well as on connection into the existing historical urban structure. A new multi-storey monolithic house with seven floors and glass façade was designed. Commercial area is located in the parterre of the house, second floor is used for offices and the roof (7th floor) gives attractive place for a café. The rest of the house (3rd to 6th floor) has a dwelling purpose. Diploma Thesis copes with the function of yard and underground parking place, as well.

The Stirling Thermodynamic Cycle
Macháček, Jan ; Sokanský, Karel (referee) ; Kyncl, Jan (referee) ; Gregor, Jan (advisor)
My doctoral thesis deals with study and analyse of Stirling thermodynamical cycle. Cycle that is composed of two isochoras and two isotherms. I describe functional principle of Stirling engine and all its parts, constructional variations of pistons system and possible engine working modes. Next chapter contains analyse of engine constructional parameters. Measuring of torque and load characteristics, p - V schemes and output work for various engine inputs is part of this analyse. There is composed mathematical engine characterization by means of Schmidt theory in chapter five. Mathematical characterization is consequently applied to engine model. Theoretical analysis and practical measurement were base for concepts, realization and verification of constructional correction. One part of my thesis is attended to design of new lamella for regenerative exchanger. For optimal lamella constructional proportions were used computational algorithm and simulations. There is concept of cogeneration unit with Stirling engine and its benefits check in last chapter. General theoretical and practical analyse of workable Stirling engine is result of my thesis. Analyse in this extent was not nowhere publishing yet. Design of regenerative exchanger lamella is then practical input of my thesis.

Advanced Electronic Circuits Simulation Methods
Kocina, Filip ; Kozek, Martin (referee) ; Kyncl, Jan (referee) ; Kunovský, Jiří (advisor)
Disertační práce se zabývá simulací elektronických obvodů. Popisuje metodu kapacitorové substituce (CSM) pro převod elektronických obvodů na elektrické obvody, jež mohou být následně řešeny pomocí numerických metod, zejména Moderní metodou Taylorovy řady (MTSM). Tato metoda se odlišuje automatickým výběrem řádu, půlením kroku v případě potřeby a rozsáhlou oblastí stability podle zvoleného řádu. V rámci disertační práce bylo autorem disertace vytvořeno specializované programové vybavení pro řešení obyčejných diferenciálních rovnic pomocí MTSM, s mnoha vylepšeními v algoritmech (v porovnání s TKSL/386). Tyto algoritmy zahrnují zjednodušování obecných výrazů na polynomy, paralelizaci nezávislou na integrační metodě atp. Tento software běží na linuxovém serveru, který komunikuje pomocí protokolu TCP/IP. Toto vybavení bylo úspěšně použito pro simulaci VLSI obvodů, jejichž řešení pomocí CSM bylo značně rychlejší a spotřebovávalo méně paměti než state-of-the-art SPICE.
