Technologies of reuse of wastewater in place of need
Podhrázský, Martin ; Ševčík, Jan (referee) ; Hlavínek, Petr (advisor)
Final thesis is focusing on possibilities hidden in the potential of wastewaters in sewers. The goal of this thesis is to present technologies and experiences with water reclamation and with heat recovery systems using wastewaters as a source of heat energy. The theoretical part is divided in two main topics. The first topic is focused on bringing important knowledge and experiences with designing and operating decentralized sewer mining systems, which are, due to less favourable environmental conditions, largely applicated and developed in countries such as Australia, California, etc. The second topic is focusing on heat recovery from sewage water and possibilities of heating and cooling buildings. A possibility of using heat energy from sewage for heating and cooling a swimming pool building located in Brno, Czech Republic was assessed in the last part of this thesis. As a source of wastewater was considered a sewer main located near the pool building. Payback periods and economical effectivity of investing into wastewater heat recovery system was compared with centralized heat supply system, which is a very common source of heat energy in Czech Republic.

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.

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.

Design and manufacture of bending fixture
Ševčík, Jan ; Trčka, Tomáš (referee) ; Zemčík, Oskar (advisor)
The work deals with the design and manufacture of bending fixture. It contains a comparsion with current bending fixtures on the market and a justification for the production of a given type. Then the work contains a proposal of the constuction of individual parts with the selection and description of technologies of their production and the process of their production. The work also contains complete drawing ducumentation of all parts of the bending fixture. The conclusion of the work contains the possibilities of design modifications and economic and technological evaluation.

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.

Back to the Future: Developing an On-Board System for a Vintage Motorcycle
Sevcik, Jan ; Juran, Radovan
This paper describes complex design of a prototypeof an on-board system for older motorcycle for measuring itsoperational characteristics. The birth of the idea is described,followed by explanation of characteristics measured by thesystem, principles of their measurement, and processing the datafor visualization on a display. The system is designed with theaim of the most minimal intervention into the construction ofthe motorcycle, but being easy to reproduce and durable enoughfor a real deployment and use while riding the motorcycle.
