Prerequisites for building magnetometer out of carbon nanotubes for geological applications
Mazanec, Martin ; Kletetschka, Günther (advisor) ; Kohout, Tomáš (referee)
This thesis is the first step in a long-therm project with object to built magnetometer from carbon nanotubes. At the beginning of the thesis is introduction to magnetism and its basic physical characteristics, brief description of the Earth's magnetic field, some magnetic minerals and material behavior in a magnetic filed. All this in a geological context. In the second part I focus on the measurment of the magnetic field, especially on some specific device. The third part deals with the allotrope of carbon - graphene structures. It offers a brief overview of thein properties, one chapter about the productiona and possible use. In discussion I try to combine these parts with a specific purpose, which is the uso of carbon nanotubes in measuring the rock magnetism. We present a simplified funcion principle of the discussed device, the first steps of construction and inicial measurment.

Modeling of meteorite impact
Takáč, Marian ; Kletetschka, Günther (advisor) ; Kohout, Tomáš (referee)
In Febuary 2013, in spectacular light and sound accompaintmen a meteorite hit the Russian Federation. Small fragment which landed in populated areas caused together with blust wave damage. The largest part broke the ice crust on the lake in outskirts of Chebarkul. The circular shaped hole gave rise to various conspiracy theories. About half of the year after impact the meteorite was lifted and conspiracy theories boken. The event immediately raised interest in the issue of the impacts of meteorites and phenomena associated with them. Processes when the meteor is passing trough atmosphere, impact craters, their origin and characteristics, computer models, types of meteorites and their origin. Or just a mystery of the hole in the ice crust of the lake Chebarkul. Science has got answers for such toppics. This paper is just trying to summarize them.

Possibilities of SinuTrain software in programming of CNC machine tools
Kohout, Tomáš ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis illustrates the potential use of software SinuTrain for programming CNC machine tools on the component Sugar Bowl. First of all, Sinumerik 840D control system - ShopTurn is briefly positioned among other control systems. Subsequently, the technological preparation of production is processed for the two alternatives. The first one is production version from the rod blank 160 mm and the second one is production variant from a pre-cast. NC programs are created for the production of components of both technological options of Sugar Bowl in the software SinuTrain 6.3 - 6.4 V Open ShopTurn. The variants of technological solutions are compared with each other in the technical-economic evaluation. The pre-cast variant is better for manufacturing more than 50 pieces of the Sugar Bowls.

Development of aplications in Ruby language
KOHOUT, Tomáš
This work is engaged in a script language Ruby and its enlargement Ruby on Rails for developing web aplications. It is attended to features of Ruby language in different examples. It illustrates bindings between Ruby and Ruby on Rails framework. It describes techniques and procedures for developing aplications in this language. Furthermore it is focused on development tools and suitable environments for a production in Ruby (Ruby on Rails). It tries to compare Ruby with the other programming languages and it sums up the facilities of programmers in Ruby. Part of this work is a project of concrete aplication in Ruby language {--} web server of sudoku with complete documentation, developing schemes (UML) and complete source codes.
