Blood pressure monitor
Kučera, Michal ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This thesis deals with the design and realization of a prototype of non-invasive blood pressure monitor based on the principle of Korotkoff sound detection. The design compares this method of measuring blood pressure with other methods. This design of an automated measuring system, which is controlled by a microprocessor, utilizes the scanning of Korotkoff sounds with an electret microphone placed in the cuff. The microphone signal is then amplified, filtered and adjusted for evaluation. The prototype uses processor-controlled inflation by the compressor and deflation of the cuff by a valve that is open without applied voltage.

Stochastic discrete modeling of progressive damage in concrete structures
Kučera, Michal ; Sadílek, Václav (referee) ; Vořechovský, Miroslav (advisor)
The work focuses on the statistical strength of structures made of quasi-brittle ma- terials, specifically concrete. Special attention is paid to the influence of the size of the structure on strength and on the entire process of material failure during loading. The mechanics of these processes are modeled using discrete models, and these models are also considered in a probabilistic variant with spatially variable material parameters. Spatial variability is then modeled using random fields. The work clarifies the effect of diffuse damage in the volume of the structure before reaching the maximum load on the further course of dissipative processes, especially on the shape of the fracture process zone and subsequently on its interaction with the random variability of material parame- ters in eccentrically drawn dogbone-shaped bodies. In addition to the tools of stochastic computer fracture mechanics, an analytical model based on averaging and subsequent analysis of the minimum of the random field is presented

Proposal for Project of Map Portal in Voluntary Association of Municipalities
Kučera, Michal ; Doskočil, Radek (referee) ; Smolíková, Lenka (advisor)
The diploma thesis is focused on the design of a map portal project for a voluntary association municipalities „Severovýchod“, which associates 43 municipalities, mainly from the Kyjov region. The map portal is commonly used by the municipality to administer the municipality. However, it also contains a number of data that are interesting to the general public. Due to the display of data directly in the map and the possibility of changing the underlying maps, this is an interesting form of data sharing.

Analysis of 110 kV distribution network in the Otrokovice nodal area
Vachutka, Ondřej ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
Master's thesis deals with analysis of distribution network 110 kV in south Moravia area. Therefore it makes basic description of the scope EG.D, a.s. company, current state of the 110 kV electricity network and their development. The practical part of the master's thesis is focused on the transmission capacity of the 110 kV wiring and the voltage monitoring in the substation during winter network load. Simulations were constructed for analysis of network load for the years 2020, 2025, 2030 and 2035. Steady state was calculated for the normal state as well as for the emergency state (N-1). The analysis was created to ensure 110 kV distribution network in the nodal area Otrokovice during the failure of the entire 400/110 kV Otrokovice transformation station for the years 2025, 2030 and the design of a new 400/110 kV substation.

Stochastic discrete modeling of progressive damage of concrete structures
Kučera, Michal ; Sadílek, Václav (referee) ; Vořechovský, Miroslav (advisor)
The work focuses on the use of deterministic discrete modeling with representation of spatial randomness in material parameters to simulate a series of experimental tests of concrete specimens in the shape of a dog bone, loaded in excentric uniaxial tension. The main focus is on the influence of the size of the structure on its mechanical properties, especially nominal strength (Size effect). The specimens are modeled as a plane stress problem using available discrete computational methods.

Proposal of measures in the low voltage network for the implementation of renewable sources and electromobility according to scenarios NAP SG
Vojtěch, Jan ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
The thesis analyzes legislative and strategic documents of the European Union and the Czech Republic which set targets in environment and energy area in 2030, alternatively in 2040. The individual chapter is dedicated to national action plans, where the most important is National Action Plan for Smart Grids setting specific requirements for future development of smart grids. The thesis contains analysis of distribution network in the municipality of Následovice and simplifying assumptions for the implementation of calculation. There are also introduced scenarios which have been used for the calculation of the distribution network with its results. Potential defects of the distribution network are commented with suggested solutions. The calculations were repeated to verify the solutions. Results are recapitulated in an individual chapter. Graphical outputs of the calculations can be found in the attachement.

Cartographic and geoinformatic evaluation of current bathymetric maps.
Kučera, Michal ; Jaroš, Jakub (advisor) ; Žáková, Zuzana (referee)
Cartographic and geoinformatic evaluation of current bathymetric maps Abstract This thesis is focusing on methods used in the process of creating bathymetric maps of lakes. In the first part of the thesis are described methods used for shoreline mapping and possibilities of depth measurements. In the theoretical part are also described interpolation methods which could be applied on point datasets. At first is given general description of these methods and after that follows also the detailed description of these methods in ArcGIS. Next part of the thesis describes cartographic methods used in bathymetry and in this part are also evaluated current bathymetric maps. The main discussion in this part is regarding cartographic and geoinformatic methods used in the process of creation these maps. In the last part is suggested a new attitude in this process and there are also created bathymetric maps using new combination of cartographic methods. These maps are enclosed at the end of the thesis. Key words: bathymetry, map, gis, cartography, interpolation
