Design of Handheld Anemometer
Valentová, Radka ; Rubínová, Dana (referee) ; Sládek, Josef (advisor)
This bachelor thesis deals with the design of a handheld anemometer. The main issues addressed are the ease of operation during use, the shaping for a more secure but ergonomic grip, the coherence of the shape of the anemometer in relation to the propeller and other parts. The design should meet both ergonomic and aesthetic requirements. The overall design of the shaping of the product is simple and functional. The handheld anemometer has a wide range of applications and can be used in other sectors besides sports and recreational activities.

On the modern technologies of hole production in metal materials
Laňka, Lubomír ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis is focused on the modern technologies for the hole production in metal materials. In the first part the fundamental technologies are described including how to make the hole or to modify it. The second part deals with the modern cutting tools, and the other part includes some machines for hole production. Some non-conventional methods of hole machining are also mentioned. The last two parts deals with the experiments - the tool wear and other phenomena are evaluated when machining some selected materials. The work confirms that the titanium alloy is a material very difficult to drill up today.

Removal of burrs during production from flat semi-finished product
Máslo, Jiří ; Trčka, Tomáš (referee) ; Kalivoda, Milan (advisor)
This bachelor’s thesis explains the definition of burr formation in individual methods of machining, there are ale described mothods of deburring, both conventional and many unconvetional methods. A large part of the bachelor’s thesis is focused on the removal of burrs from drilled holes, there are a lot of special deburring tools on offer. Experiment is performed in the last part, in which several manual methods for deburring are tested on simple components.

Semigroups of lattice points
Scholle, Marek ; Kepka, Tomáš (advisor) ; Šaroch, Jan (referee)
The thesis deals with subsemigroups of (Nm 0 , +), a special discussion is later devoted to the cases m = 1, m = 2 and m = 3. We prove that a subsemigroup of Nm 0 is finitely generated if and only if its generated cone is finitely generated (equivalently polyhedral) and we describe basic topological properties of such cones. We give a few examples illustrating that conditions sufficient for finite generation in N2 0 can not be easily trans- ferred to higher dimensions. We define the Hilbert basis and the related notion of Carathéodory's rank. Besides their basic properties we prove that Carathédory's rank of a subsemigroup of Nm 0 , m = 1, 2, 3, is less than or equal to m. A particular attention is devoted to the subsemigroups containing non-trivial subsemigroups of "subtractive" elements.
