The Studies During the Engagement Organizations
Čížková, Šárka ; Prášil, Jiří (referee) ; Jurová, Marie (advisor)
This diploma thesis is named The Optimization of the During Contract Chosen Through Company. It deals with an order management in ABC company which is focused on construction and service of telecommunication networks. The thesis is consist of theoretical background and analysis of current situation of the company. The first part is focused on theoretical background which are crucial for understanding to bussines process management. The analysis of current situation describes how the ordes is managed nowday. The thesis also contains suggestions how to solve determinated problems. This may lead to obtaining of new orders, increasing of satisfaction of customers, and increasing of competititvness of the company.

Techniques solving the fiber optic dispersion on current optical links
Prášil, Jiří ; Pfeifer, Václav (referee) ; Reichert, Pavel (advisor)
This diploma thesis deals with analysis of current diagnostic methods of optical networks, and it is focused on optical fiber dispersion in singlemode fibers. The work starts with a describtion chromatic dispersion and polarization mode dispersion, causes of and thein influence on the transmitted signal at the beginning. There are set out principles and their appropriate use in the list of measuring methods. Furthermore, the work are given the current possibilities for compensation above dispersions. The sixth chapter deals with the measurements and simulations of real routes in the OptiSystem. There are given appropriate compensation methods for the selected route speeds in the last chapter. The simulation is performed for the bit rate 2.5 Gbit / s, 10 Gbit / s and 40 Gbit / s.

Stress and strength analysis of the bike frame and compliance assessment at selected construction places.
Prášil, Jiří ; Horníková, Jana (referee) ; Vrbka, Jan (advisor)
Purpose of this work was the realization of stress and strenght analysis of the bike frame with the help of the basic elasticity approach. At first I had to transfer this task from three-dimensional to two-dimensional and also to simplify to fulfill the beam conditions. I also focused on static safety of the construction. This static safety was solved for two loading modes. First one was define as the load, which cyclist can induce, when he is going on the direct road. Second one was defined as the load, which he can induce, when he is going up to the hill. I used for these calculations mathematical software such as Mathcad 14 or Maple 12, but also modeling software especially Autocad for establishing correct dimensions. At the end I checked the stress and strain analysis obtained by the basic elasticity approach with the solution performed making use of the ANSYS software code.
