Stabilized operation of a 400 kV power line
Girga, Eduard ; Špaček, Jaroslav (referee) ; Blažek, Vladimír (advisor)
Electrical wiring 400 kV is the most used transfer wiring in the Czech Republic with length over three thousand kilometers. It is frequently used for running out significant output from the big power plants and for its significance in electrical engineering. Theoretical part of this thesis deals with the cross-section of mainly used methods for high and extra high stable wiring voltage solution. These methods can be generally dividend into precise and rough. Both of these methods will be analyzed in next chapters. Exact solution comes out from the presumption of equally spaced parameters. The rough solution uses substitution of double gates wiring, this method is accurate enough and accelerates the calculation. Former mentioned reasons explains it’s often use in technical practice. The electric line is substituted by T-cell, II-cell or Steinmetz cell according to length and required precision. Special method of rough solution is the broad method which enables to solve randomly knotted network by using II-cell to replace electric wiring between single knots. This method is mentioned in thesis for completeness; the network solved by me is not knotted. Part of the theoretical thesis is the analysis of specific transfer cases. In computing part will be mentioned not only the computation of stable wiring state with precise an rough method - with all former mentioned cell but the computation of specific transfer cases as well. In the end will be concluded all the counts from computing part and from precision view evaluated used methods of the stable wiring solution.

Methods for measuring the bit rate on the Internet
Pilčík, Jan ; Mišurec, Jiří (referee) ; Zeman, Václav (advisor)
Due to a signifikant development of computer networks in the last few years the demands for measurement of network metrics increased. This master´s thesis is dealing with standards for testing and test techniques used for the measurement of network metrics. Further it compares the existing free accessible measurement tools and metrics measures them. Finaly the thesis draws up a web application for measurement of the basic network metrics.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

Analysis of traffic lanes joining processes
Mikolášek, Igor ; Všetečka, Martin (referee) ; Holcner, Petr (advisor)
The aim of this paper is to analyse the behaviour of the traffic flow at an area of merging traffic lanes where an application of the zip rule is expected, accoding to the law no. 361/2000 Sb. “o provozu na pozemních komunikacích”. Žabovřeská street, part of the VMO Brno, in the direction from Královopolské tunely to Hlinky interchange was chosen for observation and measuring. Observation, first-hand measurement, radars, and other available means were used for data collection. On the basis of data analysis, several suggestions for improvements are made. These are aimed at increasing the bottleneck capacity. One of the suggestions is tested in a simulation program Aimsun.

Application of LEAN and TOC to solve the problem of low capacity of fabric cutting machine.
Šimon, Jan ; Martínez, Felipe (advisor) ; Hykš, Ondřej (referee)
This thesis deals with the application of the methodology LEAN and TOC to solve the problem of low capacity of fabric cutting machine. The aim of the thesis is to apply LEAN and TOC methodology to propose solutions for continuous improvement of cutting process. To solve the problem itself is used mainly principle of five focusing steps, which is based on the theory of constraints and which is described in the theoretical part of the thesis. The theoretical part also introduces some methods and tools of lean management, which are already in place in the company BOS Automotive Products CZ, s.r.o, also their specific applications are demonstrated. During research was identified a potential source of continuous improvement. This source are data that constantly sends cutter during operation. In conclusion are summarized results and suggestions for improvement based on the used principles and recommendations for further improvement.

Callcentrum System Management in a chosen Firm
Guzi, Jan ; Černý, Jan (advisor) ; Novák, Michal (referee)
This thesis deals with operational management of an inbound call center and planning necessary work capacities. Company BEZREKLAMKY Ltd. established its own inbound call center, as a reaction to the dissatisfaction with the services of an external service provider and it is necessary to properly optimize operational capacities and human resources necessary to serve 5 to 7 thousand customer callers per month. Practical part of the thesis - planning of the workforce capacity, scheduling the shifts and planning the opening hours of the inbound call center - works with a rather extensive theoretical platform, which brings new views of operations management inbound call centre and also works with the internal and external surveys related to the functionality of newly established inbound call centre. Conclusions made on the basis of the theoretical part were applied directly to the planning and operational management of the inbound customer call centre. This thesis helped applied over 25 conclusions for the studied inbound call centers. The goals, which the company set out to fulfill, while planning the new department, are then partly validated via models of system dynamics and in the last section of the thesis reflects on the extent to which these goals are feasible.
