Hydraulic losses during unsteady flow of liquid in a pipe
Svoboda, Jakub ; Pochylý, František (referee) ; Habán, Vladimír (advisor)
This thesis is focused on solving hydraulic losses during unsteady flow of liquid in pipe for both laminar and turbulent flow in smooth pipes. Radial viscosity distribution is assumed to be the same as for steady flow. Viscosity distribution is derived from velocity profile, which is mathematically described with suitably chosen function. Laplace images of unsteady velocity profile and mean velocity in cross-section are derived depending on pressure difference. Loss coefficient is derived and on base of transfer matrix method, self-numbers are calculated. Self-numbers represent attenuation and own frequency. Self-numbers are compared to values from software called “F-ACHAR” and loss coefficient is compared to the one for quasi-steady method.

Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.

Design of Process Management Elements in the International Consulting Company
Svoboda, Jakub ; Špetla, Ondřej (referee) ; Videcká, Zdeňka (advisor)
The thesis is focused on the identification of service and administrative processes and sub processes inside the chosen company and proposal of their possible separation and outsourcing using the Business Process Management methods. Potential changes should be aimed to release capacity of the monitored team of the company and optimize their processes and related capacity during busy season and also from the long term perspective. The company set the conditions for potential changes by keeping current standards about quality of products and services and keeping current rules for client communication. Additionally company expects decreasing of personal costs related to inquired services.

Possibilities of thorium utilization in current NPPs
Svoboda, Josef ; Praze, Jan Prehradný, ÚE FS ČVUT v (referee) ; Katovský, Karel (advisor)
Nuclear power plants provide about 11 percent of the world's electricity production. For fission process is uranium fuels used with varying percentage of enrichment 235U for most of nuclear reactors. Uranium reserves are reducing and their mining cost increases. Therefore, the thorium fuel is discussed as revolution fuel for current and future nuclear power plants. This diploma thesis deals with possibility of thorium fuel utilization at various types of nuclear reactors with a focus on light water reactors. The practical part of the thesis is focused on simulation and calculations of various uranium dioxide and thorium dioxide layers at the fuel rods. Model of WWER 440 reactor was developed for the calculations with the addition of thorium fuel. The model simulates burning out of fuel for 5 years, with monitoring of fuel behavior and tracking changes of each material. The thesis tries to define the suitable ratio and parameters of layers combination of uranium and thorium fuel. For these ratios and parameters the thesis tries to give sufficient amount of computational analyzes.
