Martin Lhota Formula Student Front Chassis Part Design DW, IAE, 2011, 75 pp, 62 pics The aim of the thesis is to suggest a suitable configuration of Formula Student Car’s front part of a frame according to current rules of SAE organization in the Formula Student competition. In this proposal low weight, manufacturability and sufficient torsion rigidity were preferred, whereas previously suggested solutions were reflected. At first there is presented a list of important SAE rules for the construction of front part followed by a short recherché of development of the constructional solution of frames and frames suitable for Formula Students car. Secondly there is described process during frame construction design and its computational model for the analysis which simulates torsion with the support of MKP system. Gained results and some parameters of the frame are compared with similar version of the frame construction which was suggested and made for the first Formula Student Car of our University. Moreover, there is also presented summary of suggested frame and also recommendation with possible alternatives for the next development.

Testing of QoS support in experimental data network
Fogl, Miroslav ; Škorpil, Vladislav (referee) ; Novotný, Vít (advisor)
This work deals with the qualitative requirements on services in IP networks based on technology Ethernet. We describe basic methods for imposing quality control mechanisms on services within networks. We elaborate on the ways, in which packets can be handled, overload controlled and transfer speed in network elements limited. Attention is given also to the Network Layer and Link Layer. Based on concrete specifications of network devices in UTKO laboratory an experimental network was designed and constructed. Network consisting of routers and switches linked several servers with client stations. Various types of data transfers (VoIP, HTTP, FTP, video) were generated. Several techniques for handling packets with different priorities were verified and compared. We observed that, in situations when connections are under full load, implementation of QoS support in the network becomes very important. This observation was confirmed by measurements. We also measured the parameters of the system during simulations of various situations, such as overload of a connection due to unsolicited operations or failure of a connection between routers. In order to guarantee the quality of services it is necessary to create a domain, in which rules are consistently observed in all network elements.

The effect of the rules change in 2010 on shooting of NBL players
SVOBODA, Václav
The aim of our diploma thesis is to identify and evaluate the impact of rules changes in 2010 on success of two-point shooting and three-point shooting between selected Czech and foreign players taking part in National Basketball League who have met with our specified conditions in examined seasons 2009/10 and 2010/11. There are following methods used in the very research in the empirical part: Student´s paired t-test, Two-sample F-test, Student´s unpaired t-test of equality of variances and Size of effect. The results of these tests has statistically confirmed our hypotheses H1 and H2 it means decreasing of two-point shooting success in season 2010/11 for all examined players and reducing of success at three-point throws between players with Czech nationality. On the contrary, it has not confirmed the hypothesis H3, thus increasing of three-point shooting success in season 2010/11 between foreign players. Substantively, I consider as a essential result the 20,1% impact of the rules changes on success of three-point shooting for players of Czech nationality.
