Pěstování vybraných druhů rostlin pro energetické využitíŠVEC, Miroslav January 2018 (has links)
This diploma thesis on the topic "Cultivation of selected plant species for energy use" in the first chapters of the theoretical part deals with Czech and world energy. The chapters on renewable energy sources and the possibilities of using biomass for plants for energy purposes follow. The research also deals with grasslands as alternative energy sources with a focus on direct burning. The last chapters of the research are focused on the cultivation of selected energy crops, such as the Elymus elongatus grass (subspecies Ponticus, Szarvasi-1) and Miscanthus × giganteus. The practical part describes the establishment, nursing and harvesting of small-scale experiments of Szarvasi-1 grass and Miscanthus × giganteus grass varieties, which were cultivated on the premises of the University of South Bohemia in České Budějovice and were grown as energy crops for direct incineration. Experiments with the Szarvas-1 cultivation took place in three types of farming. The first variation was the so-called "extensive" form where the plants were not fertilized with any fertilizer. The second form of farming was the "intensive" variant, in which the fertilizer was fertilized with mineral fertilizers. The last variant labeled "digestate" was fertilized with organic fertilizer. Maloparcelian experiments with Miscanthus × giganteus were carried out only in one variation of cultivation than Szarvasi-1, "intensive". For both varieties of energy crops harvested in spring 2013 and for all cultivation variants, the yield potentials from the last five years of vegetation of these cultures were evaluated after a six-year vegetation period. The evaluated parameters were in particular the yields of fresh matter and dry matter in t ha-1, but also the average solids content in %. These results were recorded and compared with specialist literature. The results of the work show that Miscanthus × giganteus yields on average higher yields than Szarvasi-1, which surprisingly best responds to organic fertilizer fertilization.

Informovanost obyvatelstva o ropné nouzi na území Jihočeského kraje / Public awareness about the oil shortage in the South Bohemian regionVACEK, Jan January 2018 (has links)
The diploma thesis is focused on the assessment of the level of public awareness on the issue of oil shortage in the territory of the South Bohemian Region and the comparsion of the obtained data with the results obtained in the region of Pilsen. The results of this research are linked to the second objective of proposing measures to improve the information system on the given issue. For the needs of the thesis, quantitative research was chosen as a questionnaire survey. The questionnaire itself consists of 17 semi closed questions, with 3 filtering questions in the introduction, ranking respondents by sex, age and municipality, followed by 14 specific questions. The purpose of the research is to determine the level of public awareness of possible regulatory measures related to the declaration of the state of oil shortage, focusing on fuel shortages, powers of state administration and self-government authorities and a general overview of the oil security of the Czech Republic. The data obtained suggest that the average knowledge of the correct answers averages around 65 % on average, but succes rates vary from 30 to 94 %. Questions with a low average success of the right answers are potential topics for improving awareness, for example through short TV spots, training courses, or information brochures. The diploma thesis can be used for educational purposes as a starting material for follow-up research, or it can serve as an inspiration for finding a suitable way of communicating with the public in the field of crisis management.

Blackout a jeho dopad na záchranou zdravotnickou službu / Blackout and Its Impact on the Emergency Medical ServiceBÖHM, Pavel January 2011 (has links)
At present, due to the use of different technologies, it is hard to think of any human activity that does not demand electric power. It is necessary to be prepared for of large-scale long-term blackouts. Possible scenarios of the occurrence of such a crisis situation must be analyzed and the crisis management must be prepared; primarily to minimize the impact on the lives and health of the population, their property and also natural environment. The objective of the thesis was to identify the operational readiness of regional centers of Emergency Medical Services in the Czech Republic for the possibility of blackouts and to create a survey of power supply possibilities to the operating center of the Emergency Medical Services. The questionnaire was focused on the analysis of operational readiness of regional centers for total blackout, on the framework of their technical support in alternative energy production and its time sustainability. The documents analysis included a pattern plan of the Ministry of Trade and Industry of the Czech Republic and an operational plan for the occurrence of a crisis situation - large-scale electric power supply disturbances, and other internal regional documents concerning the situation during a blackout. The outcomes of the thesis can be used as a background material for the comparison of emergency blackout preparedness in international environment. They can be used to achieve certain standards in the field of sustainable alternative energy supply of Emergency Medical Services centers.

Inovace informačního systému v energetice / IT Innovations in the energy sectorKorych, Jan January 2014 (has links)
This thesis focuses on innovation of ICT in the energetics sector, particularly in the heating sector. This topic is discussed in terms of both theory and practice. The main goal of this thesis is to show by the example of specific ICT innovations how to properly prepare them. The theoretical part deals with the comparison academic approaches and the approach of the leading Czech supplier of software solutions. It compares the principle of multidimensionality of MMDIS method and methods of Unicorn ES Powered Company.

Zhodnocení investičního záměru dostavby JETE / Evaluation of the investment project of the JETE completionKouklík, Michal January 2013 (has links)
The thesis deals with the project of the construction of the Temelin Nuclear Power Plant, as an optimal new production source of electrical energy to ensure the majority of the coverage of the growing electric consumption in the Czech Republic and to ensure the state energy independence in the future. The main part of the thesis is dedicated to the methods of strategic investments evaluation. Emphasis is placed on the dynamic methods, which are also working with the factors of time and risk, which are relevant in this case, because the project time horizon is 70 years. The investment project is evaluated from the perspective of owners, as well as from the overall perspective of owners and creditors. The Monte-Carlo method was implemented into the model to support the decision-making process and to move closer to reality. The method assigns the relevant distribution division to the model input values. The output is the set of available values, and the probability of their occurrence. The main thesis objective lies in the decision of the decision maker with a neutral attitude to risk, whether accept the investment or not.
