Measurements of small flow in water service connections
Stehlíková, Veronika ; Ševčík, jiří (referee) ; Tuhovčák, Ladislav (advisor)
In the first part of this thesis the basic information about the losses of water and their reporting are described. There are presented the means and methods of reducing water losses and their suitability for use. Finally, general information about water meters are presented and the UFR device is briefly described. The second part of the thesis is devoted to testing water meter and UFR device on specific water connection in a family house. The thesis resulted in the author's general recommendations for owners and operators of water supply networks.

Study of mechanism and kinetics of hexa-1,5-diene polymerisation catalyzed by phenoxy-imine titanium complex and MAO
Ševčík, Jan ; Cihlář, Jaroslav (referee) ; Hermanová, Soňa (advisor)
This diploma thesis is focused on study of polymerization of hexa-1,5-diene catalyzed by phenoxy-imine titanium dichloride (FI Ti) and methylaluminoxane (MAO) as cocatalyst. Effect of monomer concentration, polymerization temperature and cocatalyst/catalyst ratio on catalytic activity, molecular weights, polydispersities and particularly microstructure of prepared poly(hexa-1,5-diene) was studied. 1H NMR spectroscopy revealed that the poly(hexa-1,5-diene) microstructure contained methylene-1,3-cyclopentane (MCP) as well as vinyl tetramethylene (VTM) units. Kinetics of this polymerization was studied. Finally, copolymer of ethene and hexa-1,5-diene possessing incorporated pendant vinyl group was prepared.

Study population of bacteria by image analysis methods
Ševčík, Jan ; Veselá, Mária (referee) ; Zmeškal, Oldřich (advisor)
This bachelor thesis is focused on monitoring and application of image analysis methods on Bacillus megaterium and Cupriavidus necator bacteria. The introduction describes a general knowledge about bacteria, microscopic and image analysis methods. At first it was necessary to prepare suitable microscopic specimens using Gram staining for the observation of a bacteria cell. Every picture of bacteria was taken using a CCD camera and a microscope. Box–Counting method was used to identify the optimal threshold value, corresponding to their fractal measure (or surface areas covered with bacteria) and fractal dimension (or entropy of their arrangement on the surface area). After thresholding, the images were further processed using the Mass–Radius method, which defines a distribution of bacteria relative to the centroid of a cluster.

Suspensions of passenger and race cars
Ševčík, Jan ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
Bachelor thesis focuses on comparing different types of axles between them with emphasis on changing the geometry during propružení.In student version of Autodesk Inventor Professional was created virtual models of axles and virtual test polygon. The output of the program are a series of images showing the axle during springing. Changes in geometry are quoted, described and analyzed. In conclusion there are compared to civil rights and race suspension.

The offer price of building
Ševčík, Jaroslav ; Comorek, Martin (referee) ; Marková, Leonora (advisor)
The aim of this bachelor thesis is to evaluate the building for which a tender for a contractor. The theoretical part deals with pricing during the life cycle of a construction project. In the practical part I have also given an alternative material solutions specified project documentation and I set the final offer price to the investor. The Offer Price is set to the original specifications, and my proposed alternative solutions.

Crime and Religion
Ševčík, Jan ; Kovanda, Lukáš (advisor) ; Svoboda, Miroslav (referee)
This bachelor thesis analyzes relationship between number of Christians and criminality. It tests a hypothesis that there is a negative effect of number of religious people on number of crimes. This effect is tested on 7 categories of crime: murder, rape, assault, burglary, larceny, robbery and total crime. Data used in model are from 2011, when there was a census in Czech Republic. 14 regions of Czech Republic are analyzed with OLS method. Negative effect of religion was found statistically significant on burglary and total crime.
