Simulation of the energy recovery circuit function
Kubíček, Ondřej ; Ficza, Ildikó (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis describes the design and optimization of a mathematical model for simulating the hydrostatic energy recovery systems. The mathematical model together with the experimental stand should be used to simulate the operating conditions of vehicles using the hydrostatic energy transmission. These include vehicles for collection of municipal waste, public transport vehicles, or for heavy construction machinery. The paper summarizes the current efforts in the design of analytical models, describes the program developed in MATLAB, and is devoted to analyzing the influence of individual input parameters on the output calculation.

Design of heat exchanger for feeding heat water network 5,5 MW
Kubíček, Ondřej ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
The Master thesis deals with the water-heater design for heat-exchange station with total power output 5,5 MW. The goal of the thesis is to make thermal and hydraulic calculation in the extent of the assignment and to develop a projection drawing of the heater along with a correct dimensioning of the shell and flanges. Thesis goals were met according to the assignment. The introductory part of the thesis briefly introduces to the heat-exchanger problematic and selected topics about heat-transfer. Following the basic mass and energy flows calculation inside the heater together with the thermal and hydraulic design determines the size of the heat transfer surface of pipes. After that the design calculations were made, whose results are used to determine the basic dimensions of selected parts and checking the accuracy of designed dimensions. In the last part of the work the design process is more described also with a more detailed description of selected parts.

Bridge on the II/379 road
Kubíček, Ondřej ; Šustr, Bronislav (referee) ; Panáček, Josef (advisor)
The master´s thesis deals with a new road bridge on the road II/379. There are three possible variants in preliminary design but only the option of connected girder slab beam of four fields was selected. This variant was assessed by static calculation in accordance with European standards. Other important parts of this thesis are also drawings, construction progress, visualisation and technical report.

Development of divergent-flow isoelectric focusing chip for separation of biological agents
Duša, Filip ; Šalplachta, Jiří ; Horká, Marie ; Lunerová, K. ; Rosenbergová, K. ; Kubíček, O.
Isoelectric focusing (IEF) is an efficient method for separation of different bacterium species. Divergent flow format of IEF (DF-IEF) enables continual separation of large volumes of samples and fractionation of the separated analytes for later analysis. The mentioned properties enabled development of DF-IEF chip for separation of H2O2 inactivated biological agents (B-agents). The chip was designed to perform separation in vertical alignment which solved issues connected with sedimentation of bacterial cells. The separation method was optimized using colored markers of isoelectric point and four different b-agents were separated using the DF-IEF chip. The obtained fractions were subsequently analyzed with matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS). The mass spectra proved that the developed DF-IEF chip is an effective tool for separation of inactivated B-agents.

Demographic ageing and the city: seniors in Karlín
Kubíček, Ondřej ; Matoušek, Roman (advisor) ; Galčanová, Lucie (referee)
The following thesis addresses the process of growing old in an urban environment. It concentrates on the factors, which infulence the quality of senior citizens' lives and how they do it. The main focus is put on the city disticts that are subject to dynamic changes caused by the processes of post-socialist transformations, revitalization and gentrification. The thesis explores the problems but also the benefits, which these changes can bring to elderly citizens' every day lives. Looking for the answers to these questions is based on the case study of a city district in Prague - Karlín. The qualitative research have been done by semistructured interviews with local senior citizens. It has shown possible perception of some aspects of environment of Karlin and changes of this environment.
