Design of Centrifugal Pump Using Differential Geometry Methods
Sloupenský, Zdeněk ; Varchola, Michal (referee) ; Melichar, Jan (referee) ; Drábková, Sylva (referee) ; Pochylý, František (advisor)
This thesis deals with a new approach to the design of impeller, blade and spiral of centrifugal pump. The mathematic model of flow inside meridional section of impeller and spiral is based on the instruments of differential geometry applied to Bezier surfaces. This formerly introduced theory is more deeply developed in this thesis and the conclusions are applied to the design of centrifugal pump parts working with fluid. The main thesis output is the mathematic model and on its principles created software determined for the design of impeller, blade and spiral. The received results are exportable into one of the commonly used 3D modeling programs.

Possibilities of clay plasters shrinkage elimination
Melichar, Jindřich ; Koplík, Jan (referee) ; Opravil, Tomáš (advisor)
Earth plasters which are applicated in interiers don´t have just an estetic, but mainly heat storage function. To accomplish better storage properties the plaster has to be laid on the wall in sufficient thick ply. But this use to be accompained by creating of cracks during dehydration of the plaster. This bachelor work will be considering possibilities of elliminating this negative event by additing suitable components to suppress shrinkage and cracks by creating ettringite.

The influence of telecommunication transmitters on the aesthetic value of landscape
Binderová, Vanda ; Melichar, Jan (advisor) ; Kaprová, Kateřina (referee)
The thesis deals with the influence of telecommunication transmitters on the aesthetic value of landscape. It uses both environmental and sociological approach. Subject of investigation is the relationship between the aesthetic stimulus (landscape) and the recipient (man). For the analysis, Scenic Beauty Estimation Method is used as a psychological procedure which measures aesthetic preferences and allows adequately assess how society perceives the presence of various types of telecommunication transmitters in the landscape, including the so-called camouflage. Analysis also includes a comparison of affected and unaffected groups. The aim of the thesis is to assess whether the perception of the presence of telecommunication transmitters in the landscape is negative. The thesis deals with hypothesis that "camouflages" reduce the negative perception of telecommunication transmitters in the landscape.
