Biometric fingerprint identification
Dašek, Filip ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
In biometrics we use distinctive physical features for identification and verification of identity. The most famous technique is identification by fingerprints. This technique use unique structure created by papillary lines for unambiguous identification. Thesis contains methods which were created throughout the years for analysis and adjustments of fingerprint. The algorithm is based on compairng two pairs of minitua and calculating transform matrix for correct alignment

Production Comparison of High Voltage Winding of Dry Transformers
Mrajca, Miroslav ; Bulín, Tomáš (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor thesis deals with the history, importance, usage, construction and principle of the operation of transformers. The thesis also focuses on the detailed description of the parts which the dry power transformer is composed from, as well as the description of their manufactory and following assembly into one unit. The thesis contains the comparison of different technologies of manufactory of higher voltage winding and magnetic circuit. The thesis contains a process of design of the dry transformer with an example of calculation. The output is a comparison of different high voltage winding technologies in terms of production costs and winding factor.

History of Materials for Production of Cross-country skis
Ptáček, Ondřej ; Němec, Karel (referee) ; Molliková, Eva (advisor)
The present bachelor thesis is of a retrieval type. The first part deals with the development of cross-country skiing and the development of materials and technologies used in the production of cross-country skis from the mid-20th century to the present. It also explains important concepts in terms of design, shape and types of cross-country skis. Additionally, materials for cross-country ski poles are outlined and their differences are discussed. The second part refers to some of the materials used in the manufacture of cross-country skis, or cross-country ski poles. The emphasis is mainly laid on composite materials and matrices. The matrix in composites is reinforced using fibre or other type of filler.

Static solution of parking house
Tvrzník, Jakub ; Přikryl, Václav (referee) ; Zich, Miloš (advisor)
The diploma thesis is focused on the design of the supporting structure of a multi-storey parking house. Part of the work is also a search of three parking houses in our country and in Slovakia. The content of the work is a preliminary design of 3 variants of a typical ceiling structure. Subsequently, one variant is selected and processed in detail. A flexurally supported slab-wall model was created in Scia Engineer for the analysis of the structure. Selected structural elements were modeled separately. Additional assessment is performed in GEO, FINE, IDEA Statica, JORDAHL and MS Excel software.

Polygonal Mesh Segmentation
Minařík, Vojtěch ; Havel, Jiří (referee) ; Španěl, Michal (advisor)
Bachelor's thesis deals with 3D model segmentation into particular meaningful segments. Method is based on algorithm described in article Protrusion-oriented 3D mesh segmentation The realized solution is based on assumption, that 3D models consist of a core and core attached protrusions. The segmentation algorithm consists of three main steps: core approximation, selection of salient points which indicate end of protrusion and assignment of points to appropriate segments. Implementation uses library CGAL which is useful for loading and manipulating 3D meshes.

Design of oil distribution transformer
Mrajca, Miroslav ; Mach, Martin (referee) ; Ondrůšek, Čestmír (advisor)
This master thesis deals with the manufacturing process of oil distribution transformers. Firstly, the thesis devotes to the design arrangement of the magnetic circuit and its manufacturing technology. The procedure of cutting laminations for core and their building into the core. Subsequently, the thesis describes technologies used for manufacturing primary and secondary windings including procedures on winding machines. Then it deals with the production of the tank and the final assembly of the transformer into one unit. The next part of the thesis discusses the design procedure of the assigned distribution oil transformer with a numerical calculation while respecting the requirements of the standards. Finally, the costs of the material of the designed transformer are determined.

Coalition Theory for Cournot's Oligopoly Model
Eryganov, Ivan ; Osička, Ondřej (referee) ; Hrdina, Jaroslav (advisor)
This bachelor thesis is devoted to the basic theoretical aspects of game theory, to the behavior of firms in oligopoly conditions and to the building of theory which describe behaviour in cooperative oligopoly games for Cournot's oligopoly. At this work are explained important definitions and they properties are demonstrated in the examples. Further work is focused on cooperative oligopoly games, describing their properties and defining a -characteristic function. Procedure of computing it and the description of some properties of cooperative oligopoly games are demonstrated on two examples.

Making sand moulds and cores for casting
Katrňák, Jiří ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
Bachelor thesis describes various methods for the production of sand molds and cores in foundry and basic concepts associated with this issue. Due to the large number of production methods are described only basic and most widespread methods. The work includes the design and manufacture of cast-iron grate for the stove, made into a mixture of bentonite and self-hardening mixture AlpHasetTM.
