The technology of ceramic filters as a problem of their shaping
Dobrovolná, Martina ; Janíček, Martin (referee) ; Sokolář, Radomír (advisor)
The aim of this bachelor thesis is to evaluate possible production of ceramic filters made by dry pressing and to choose suitable granulate and its optimal moisture proper for this way of production. The theoretical part of the thesis explains the meaning of the usage of ceramic filters in a foundry industry. Further more, the technology of ceramic mixtures production and the technology of ceramic filters production made by wet pressing and dry pressing is drawn near in this thesis. The practical part describes the production process and the testing of experimental samples. The influence of different kinds of ceramic mixtures, their moisture and different modes of burning is compared to physical-mechanical features of ceramic potsherd. The output is to design a material with a set of typical features which would by suitable for dry pressing production.

Advanced features of traffic shaping for 802.3 and 802.11 networks under OS Linux
Pánek, Michal ; Endrle, Pavel (referee) ; Szőcs, Juraj (advisor)
This bachelor work deals with possibilities of traffic shaping and control in OS Linux. First part of the work examines indiviual tools needed for working with data stream. The second part consideres methods intended for traffic shaping. From these methods intended for use in standarts 802.3 and 802.11 were selected and described. The second part of paper focused on Hierarchical Token Bucket and Class-based queueing method. The third part is the practical application of methods on the hardware, the measurement of the individual standards and processing into charts.

Catalytic behaviour of ceramic catalytic materials
Schlosser, Radek ; Cihlář, Jaroslav (referee) ; Cihlář, Jaroslav (advisor)
In this bachelor’s thesis the methods of preparation of ceramic perovskite-like membranes for heterogenous catalysis and reformation reactions of carbohydrates were studied. The syntetic La-Ca-Fe-Ti-O type and commercial La-Ca-Fe-Co-O type powders were used. The properties such as phase purity, specific surface area and morphology of used powders were determined. Technology of processing included powder uniaxial pressing, membrane sintering and polishing their surface. Conditions for uniaxial pressing were optimized. The dependence of grain size and amount of titanium was determined.

Quality of Services in WAN
Koblížek, Michal ; Heriban, Pavel (referee) ; Šťastný, Jiří (advisor)
This bachelor thesis is inquire into direct traffic in computer network based on TCP/IP protocol. In the finish we can direct packets, that network traffic will behave by our rules. We will use only free software for this solution – this solution is based on FreeBSD system, PF packet firewall and queue framework ALTQ. Part of this thesis make examples queuing include fullversion scripts that are in elektronic appendix. The thesis was developed in research project MSM 0021630529 Intelligent Systems in Automation.
