Parametric computational model of non-food bulk materials silo
Červený, Vojtěch ; Kvarda, Daniel (referee) ; Maňas, Pavel (advisor)
This bachelor thesis deals with the creation of a parametric computational model of a bulk material silo. The work includes acquaintance with the issue of bulk materials, the theory of calculation of pressure conditions in silo, introduction of the proposed structure, creation of a parametric geometric model in the CAD system and the calculation model in the FEM system. The thesis includes a brief introduction to the software used and the principle of working with the created models.

Improving material flow by using a logistics train
Grepl, Radovan ; Urbanovský, Jan (referee) ; Zeizinger, Lukáš (advisor)
The main content of this master´s thesis is the analysis of the current state and the proposal an internal supply of assembly lines in the company Koyo Bearings s. r. o. This company specializes in the production of bearings mainly for the automotive industry. The supply of the lines operates on the principle of Mikl-run. The practical part focuses on creating a simulation model using the Plant Simulation simulation software from Siemens PLM Software. Based on the created model, several variants were proposed to optimize the loading of the packaging material. These variants were analyzed and evaluated.

Fairy tale as an inspiration for physical activities
VÁVROVSKÁ, Gabriela
The bachelor tesis is focused on movement activities of preschool aged children who are motivated by fairytale's stories. The main goal was to create a set of movement activities and also to highlight the possible connection between movement activities and fairy tales. The thesis consists of two parts. The theory part deals with a brief description of prechool age. It defines child's movement, their movement skills and abilities. If focused on the actual understanding of physical education with regard to the requirements of the Framework prechool education programme. It i salso directed on the importance of fairy tales stories in the child's life. The practical part consists of motoric activities and movement games suitable for a group of preschool aged children, that were included in the set. These activities are related to a specific fairy tale. The pilot programme has been teste dat the nursery school setting. Self reflection on the children as well as the teacher after each acitivity has been used for the evaluation of the project.

Low-temperature heat storage
Kavunov, Dmytro ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with a low-temperature heat storage used for heating buildings. The theoretical part deals with a brief research on the issue of a low-temperature heat storage. Furthermore, the work presents implemented projects using a low-temperature heat storage. In the practical part, a suitable low-temperature storage is designed, related balance calculations of its capacity and temperature profiles are performed. This part includes the creation of a model which describes the charging and discharging of the storage over time and the use of its results to test operating parameters.

New Parallel and Regulated Automata and Grammars
Kučera, Jiří ; Průša, Daniel (referee) ; Sawa, Zdeněk (referee) ; Meduna, Alexandr (advisor)
Tato práce zkoumá a zavádí čtyři nové jazykové modely se zaměřením na regulované a paralelní verze automatů a gramatik. První z modelů, stavově synchronizované systémy automatů , zavádí systémy složené z konečného počtu zásobníkových automatů jejichž činnost je řízena slovy z řídícího jazyka nad množinou stavů. Druhý model, neomezené hluboké zásobníkové automaty , je variantou hlubokých zásobníkových automatů z nichž bylo sejmuto omezení kladené na hloubku expanze na zásobníku. Třetí model, skákající čisté gramatiky , zavádí skákající gramatiky bez neterminálních symbolů. Poslední model, k#$-přepisující systémy , rozšiřuje #-přepisující systémy o přídavnou zásobníkovou paměť. Text této práce je členěn do tří částí. První část uvádí motivaci k zavedení studovaných jazykových modelů a zasazuje je do kontextu souvisejících oblastí teorie formálních jazyků. Je zde také uveden přehled o celkové organizaci práce, základních pojmů teorie formálních jazyků a současných poznatků souvisejících s předmětem výzkumu. Druhá část tvoří jádro této práce. Jsou v ní formálně definovány všechny nově zavedené jazykové modely a studována jejich vyjadřovací síla. Poslední část uzavírá tuto práci souhrnem získaných teoretických výsledků společně se souvisejícími otevřenými problémy a nastiňuje cesty dalšího výzkumu spolu s výhledy na možná využití.

Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.
