Monolithic milling tools with PVD coatings and their use
Ševčík, Jan ; Sliwková, Petra (referee) ; Jaroš, Aleš (advisor)
The bachelor thesis deals with the monolithic milling tools carbide on the surface which is deposited by a thin layer of rating on. First of all, the thesis describes the method of milling, the basic division of milling operations and milling tools, power analysis tool load. Then, it is analyzed problems of cemented carbides, its production, properties and dividing into groups. After that it is described characteristic of coating methods, especially the PVD method, and its modifications. The last part is devoted to producer’s offers of coated monolithic mills. There are introduced few selected tools and described its characteristics, geometry and application suitability.

Multifunctional building - Houbalova - construction technology project
Ševčík, Jan ; Čech, Václav (referee) ; Henková, Svatava (advisor)
The subject of this thesis is the solution of building technology project poly-functional complex with a focus on execution of construction. Gross building is designed reinforced concrete skeleton combined with masonry. Technology will be developed Code for reinforced concrete monolithic frame and masonry. On the techno-logical stage it will be processed inspection and test plan and the balance of the major sources for the implementation of reinforced concrete structures 1.NP. The thesis is a proposal for construction site, which is complemented by a social facilities and offices. For an overall view of the construction of a multifunctional complex is processed time and financial plan, which will be further elaborated for building construction B. Availability of supply is verified by the design of routes. Like other task will be processed proposal formwork system for con-struction 1.NP Building B.

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.
