Algebra of dual quaternions in image analysis
Hrubý, Jan ; Návrat, Aleš (referee) ; Hrdina, Jaroslav (advisor)
This work has two goals. Firstly it is to acquaint the reader with the classical use of quaternions and dual quaternions in geometry. Secondly the generalization of the Fourier transform into the set of dual quaternions. At first it goes into algebraic properties and structure of quaternions and ways of their inscriptions. Later dual numbers are introduced and consecutively with their help dual quaternions. Then the work deals with description of rotations and translations using quaternions and dual quaternions, that enable their easy description. Finally the discreet dual quaternion Fourier transform is defined, and for its effective calculation the algorithm is derived, which is then brought into effect as a code in program environment MATLAB.

Revitalization Program of Floral Garden in Kromeriz
Jaroš, Pavel ; Hrubý, Jan (referee) ; Šindlar, Jiljí (advisor)
My bachelor thesis is about architectural and urban revitalization of the garden called „Holandská“ and „Pomerančová“, which is part of „Květná Garden“ in Kroměříž (this landmark is registered on the list of the UNESCO heritage list. This project create new space for visitors of the „Květná“ garden the Info center, show rooms, cafe and the theater scene. Revitalizes the curent entry building, where is located library with lecture hall and study room. Project combines present baroque garden with covered area in the main axes, which results in the new functional units. Contens and spatial solution of the greenhouse and a few other individual objects („Králičí“ hill, Baroque aviary) this is also object of project

Intelligent beekeeping system
Hrubý, Jan ; Zeman, Václav (referee) ; Kiac, Martin (advisor)
The aim of this thesis is to design and develop an intelligent beekeeping system that can measure the frequency in the colony, the weight of the hive to monitor the loss or to inform the beekeeper if the bees are carrying honey. Furthermore, the security of the hive against theft is also being considered. Communication between multiple intelligent beekeeping systems is important for the functionality. This is why part of the work focuses on choosing the best possible communication, taking into consideration battery consumption and reliability. In this work, a many-to-one communication system of modules is used, which means that the number of hives can be freely expanded without affecting the functionality of the system. The resulting system is powered by a combination of battery and solar panels.

Sintering of Advanced Cubic Ceramic Materials
Hrubý, Jan ; Pouchlý, Václav (referee) ; Maca, Karel (advisor)
This bachelor's thesis deals with the literature search on preparation of advanced ceramic materials. It compares the sintering and properties of cubic ceramics with ceramic materials with different crystal structures. The experimental section is devoted to preparing tetragonal ZrO2 ceramic (doped with 3 mol% Y2O3) and cubic ZrO2 ceramic (doped with 8 mol% Y2O3). These ceramics were prepared using two-step sintering combining pressure-less sintering with hot isostatic pressing (HIP). The goal was to prepare dense ceramics with homogenous microstructure. Another studied material was Y2O3 with micrometer sized particles. Microstructure and optical properties of studied materials were evaluated.
