IMS technology testing
Kuběna, Pavel ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
This thesis is about the IMS technology, which is a standard defining the architecture for providing multimedia services. The theoretical part is a general description of the technology, architecture, a brief description of segments and used protocols. The practical part is a description of the environment of Open IMS Core and testing network designed according to theoretical knowledge. This is essentially a description and analysis of the registration process, voice transmission(it means a call between two users), text relay and video. A laboratory task was created on the basis of obtained knowledge.

Vegetable oil as a fuel for a diesel engine
Kuběna, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis offers an opportunity to get closely acquainted with ignition engines running on alternative fuels. At the beginning of this work the reader is offered a wide variety of alternative fuels since born automotive industry, their basic information, features, use, and technical issues of each fuel. In the following part of this thesis, the author deals only with vegetable oil and its potential use as a fuel in an ignition internal combustion engine. It focuses on the specific conversion vehicles, their complexity, advantages and disadvantages, the overall economy of operation and risks of using vegetable oil instead of conventional diesel fuel. There is also documented performance characteristics and ecological balance of a particular target vehicle.
