Coordinating landscape protection and needs of cities: Case study Císařská louka, Prague
Skohoutilová, Sandra ; Novotný, Vojtěch (advisor) ; Franke, Daniel (referee)
The aim of this thesis is to create design of areas with different ways of using in area of Prague 5, Císařská louka and neighborhood. This design should join the requirements of nature and landscape protection and needs of city residents. The thesis is divided into three basic parts. In the first part, in the literary research is described relationship between the city and the river, the role of the river embankment in the urban environment, systems which includes area of the riverbanks and the legislative framework mentioned issues. Next, analytical part maps area of interest within the wider context as well as the concretely chosen studied area. Findings from the two previous parts are implemented in the last part of the design. This part consists of different variants of solution showing the options of area layout in the studied area. The result is a final design which joins required coordination of nature and landscape protection and the needs of city residents.

Masterplan for "Králův Dvůr - Centrum"
Macourek, Michael ; Novotný, Vojtěch (advisor) ; Macoun, Milan (referee)
The thesis is focused on verifying of functional and dimensional arrangement of "Centrum" located in Králův Dvůr. Theoretical part is concerned on conditions for the formation of cities and settlements and socially active public spaces. With the respect to the theoretical and analytical part is proposed the location.

New approaches to the use of energy of water waves
Novotný, Vojtěch ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
Bachelor´s thesis deals with topic of utilization the energy of sea waves. Mainly describes existing devices transforming this energy into electricity, their division and on what principle they work. Thesis also contains description of sea waves. In the next part, the author designs and describes his own devices converting sea wave energy into electricity. If there is a similar device that is patented and exists author process a patent search to find out.

Influence of the Francis turbine stay vane trailing edge shape on generation of Karman vortex street
Novotný, Vojtěch ; Skoták, Aleš (referee) ; Rudolf, Pavel (advisor)
In the flow past bluff bodies for a certain range of velocity a periodical vortex shedding emerges which is known as von Kármán vortex street. This phenomenon causes the periodical alteration of pressure field which affects the body. Should the vortex shedding frequency be similar to the body natural frequency, the amplitude of vibration significantly increases which can lead to fatigue cracking. In the case of water turbines, this phenomenon often affects the stay vanes. Both the vortex shedding frequency and the lift force amplitude can be influenced by the modification of the trailing edge geometry. The aim of this thesis is to use CFD computation in order to find the optimal geometry of the stay vane trailing edge for the specific Francis turbine unit.

Verification of surface roughness and recommended cutting conditions after milling using tool with inserts
Novotný, Vojtěch ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
My bachelor’s thesis aims at practical testing inserts. The first part includes a theoretical analysis of problems connected with main tested parts. Especially, there is a description of face milling, surface structure after face milling and wear of the cutting tool. Next, an experiment is designed and performed, describing the machine used, the cutting tool, inserts, cutting conditions, material for testing and basic experiment criteria. In last part results of the test are presented and optimal value for cutting speed.

Metody navádění mechanizačních prostředků po pozemku při provádění pěstebních zásahů
Novotný, Vojtěch
Bachelor thesis entitled "Methods for guidance mechanization on land in the implementation of silvicultural interventions" aims to describe GNSS systems, the principle of their function and distribution. The first section describes the functions of GNSS and its products and related systems that are involved in signal transduction. The next section is technical settings menu and set the method for the movement of the land. The next section describes growing operations spreading fertilizer, chemical treatment of crops and crop establishment methods for using GPS. The last section shows the possible future development of satellite navigation technology in agriculture.
