Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.

Výcvik mladého koně se zaměřením na využití ve skokových soutěžích
Sejkorová, Michaela
The content of the bachelor‘s thesis on the topic "Training of a young horse with a focus on the use in jumping competitions" is the gradual development of a young horse to an adult individual with competition experience. It is divided into several chapters in which jumping competitions are first summarised in general, including the penalties in them. Other chapters deal with the requirements for selecting a jumping horse, what characteristics it should have, i.e. its exterior, character, temperament and origin. Then the proper longeing of the horse, its preparation for saddling, and the actual saddling of the horse itself, which is essential for any training of a young horse. The main part of the bachelor thesis is the basic training of the young horse. This part deals with the gradual gradation of training requirements, i.e. the work of the young horse on the riding arena and in the field, and also the work with cavalettes through gymnastic exercises to independent jumping. The conclusion of the thesis is devoted to the preparation of the young horse for the first competitions and the subsequent increase of the riding requirements for the young horse towards the participation of the horse in higher levels of competitions.

Delivery modes of courier and transport companies
Hradecký, Ondřej ; Fábry, Jan (advisor) ; Borovička, Adam (referee)
A great number of transport and courier companies exist in Czech Republic. Each of these companies offers their customers the opportunity to send all kinds of shipment to places located in our country or almost anywhere in the world. This thesis is divided into two main parts. In the first part, there is a theoretical description of two models of distribution tasks, which are relevant in terms of transport and courier services. After this theoretical description the approximation of the models to reality is made. Individual parts of the models are described on a particular situation in two different companies. The second part of the thesis presents a brief overview of courier and transport companies and the description of delivery modes from which customers can choose. Companies such as the international company DHL, PPL, Česká pošta and EPS are mentioned. Both parts of work focus on the description of time windows and penalizations associated with them.
