Air-conditioning of offices
Trávníček, Tomáš ; Pavelek, Milan (referee) ; Janotková, Eva (advisor)
The aim of a master thesis is the proposal of the air conditioning system for one floor of offices in the administrative building. Propsal of the air conditioning system is based on the calculated ventilation air, further on thermal looses, thermal gains and then psychrometric calculation for summer and winter operation. Obtained values are the basis of the proposal of the air ducts with ending parts like a diffusers. It also obtains the proposal of the air conditioning unit with design of machina room. The proposal and all calculations are supplemented with drawing documentation and list of items.

Fossil fuels use in Czech Republic
Trávníček, Tomáš ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The aim of the bachelor thesis is to collect facts about fossil fuels and their utilization in the Czech Republic. Firstly, the thesis discusses the fossil fuels and their division in general. The main part of the thesis is focused on mining and utilization of different kinds of fossil fuels in the Czech Republic with the emphasis being put on the brown coal, black coal and the natural gas. The oil and the lignite are briefly dealt with as well. The thesis includes the statistics of the fossil fuels‘ production of the mining companies, the summary of the big energy facilities in the Czech Republic and the mapping of their fuel bases.

Monitoring of GSM network
Trávníček, Tomáš ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
This master’s thesis is focused on problems of monitoring GSM network using a mobile phone. Problems are analyzed on a theoretic basis with a description of available network parameters. Then the thesis offers a description of existing application environments providing a user with given data about the network. The main part of this work describes a development of application compiling queue data from mobile network and GPS, and creates output data illustrating signal strength in selected areas. The work also includes extensive measuring in select areas together with an evaluation of the processed data.

Trajectory planning for vehicle with four steering and driven wheels
Trávníček, Tomáš ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis deals with trajectory planning and driving for two-wheel steering (2WS) and four-wheel steering (4WS) vehicle in environment with static obstacles. Algorithms, mentioned in the search, are used for planning the path for vehicles with front wheel steering. The kinematic model is ana-lyzed and simplified. The problem of trajectory planning is solved in Matlab using trajectory dis-cretization and searching within the state space. The implemented algorithm deals with obstacle collisions as long as the map is obtained, therefore the planning does not take so much computa-tional time. Finally, the algorithm is tested on a two-wheel minibike. The solution is applicable for variety of vehicles with additional movement possibilities, even when adapted it can deal with planning in the three dimensional workspace. The results of this thesis are applicable for planning for 2WS and 4WS vehicles.

Steam Turbine for Solar Power Station
Trávníček, Tomáš ; Žižka, Václav (referee) ; Fiedler, Jan (advisor)
The aim of the master’s thesis is a design of double casing condensing steam turbine with gearbox, reheat and with power output 110 MW for solar power station. The steam turbine has an axial output to the air cooled condenser. The design of the turbine is developed on the basis of concept of Doosan Skoda Power company. It is the main reason this turbine has the impulse blading. There are heat calculation and calculation of heat balance diagram in the first part of the thesis. The system of regeneration consist of three Low Pressure Feedwater Heaters (L.P. FWH), deaerator, and two High Pressure Feedwater Heaters (H.P. FWH). The next part of the thesis is focused on a flow path section of turbine. There is a selection of profile of turbine blades at this part, too. The basic design and strength calculation are available only for high-speed high pressure (HP) part of turbine, as an assignment of the thesis says. There is heat balance diagram for 75 % of nominal power output at the end of thesis. The drawing of longitudinal section of HP part of turbine is the main appendix of this thesis.

Constrained Modeling of Induction Motor Using Physical Modeling and FEM
Trávníček, Tomáš ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
Tato práce řeší návrh komplexního modelu asynchronního stroje, pomocí něhož se dá stroj analyzovat. Model se skládá z dílčích modelů, které popisují asynchronní stroj z hlediska elektro-magnetického, elektrického a tepelného. Elektromagnetický model je řešen pomocí metody koneč-ných prvků v programu zvaném FEMM. Další výpočty jsou provedeny pomocí Matlabu. Tepelný model počítá s ustáleným stavem stroje v požadovaném pracovním bodě. Elektrický model je řešen pomocí náhradního schématu, ze kterého jsou odvozeny vztahy pro elektrické veličiny. Výsledný propojený model je naprogramován v Matlabu a slouží jako nástroj pro analyzování asynchronního stroje.

Analysis of infection therapy in paediatric department I.
Trávníček, Tomáš ; Malý, Josef (advisor) ; Doseděl, Martin (referee)
Analysis of infection therapy in paediatric department I Author: Tomáš Trávníček Tutor: doc. PharmDr. Josef Malý, Ph.D. Consultant: MUDr. Magdalena Rohanová, Mgr. Petr Domecký Department of Social and Clinical Pharmacy, Faculty of Pharmacy in Hradec Králové, Charles University Introduction and aims: Infections in newborns are one of the most frequent causes of death. The aim of this work was the retrospective analysis of bacterial infection in newborns with a birth weight ≤ 1500 g hospitalized in Paediatric Intensive Care Unit (ICU) and compare it with the latest findings published in the expect literature. Methods: The retrospective cross-sectional study took place in Paediatric ICU. The data were gathered between 07/29 and 08/10 2020. The study included patients in neonatal age with a birth weight ≤ 1500 g hospitalized in the Paediatric ICU in 2018 and 2019 with bacterial infection. The infection was proved by a positive cultivation, increased C-reactive protein and increased or reduced number of white blood cells. Information on the patient, infectious agent, laboratory tests, occurrence of risk factors for sepsis, selection of antibiotics, its susceptibility, dose, dosing interval and duration of administration, as well as the result of therapy were collected to a prepared form. The data were...
