Preliminary aerodynamic analysis of remotely controlled model with jet propulsion
Novák, Ondřej ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This bachelor´s thesis deals with aerodynamic analysis of unmanned aircraft and subsequent changes to design of wing, its position and wing-fuselage junction. In this work emphasis is laid on flow separation, its interaction with other flow structures and its influence on aerodynamic properties. The goal of these changes to the aircraft is ensuring sufficient stability and controllability in low as well as high angle of attack flight. AVL, XFLR5 and CFD methods were used in the thesis. In case of inaccuracy of CFD calculation, two backup wing related modifications were prepared.

Computational modeling of flow field with separation
Šamša, Petr ; Elcner, Jakub (referee) ; Jícha, Miroslav (advisor)
This diploma thesis is considering with computational modeling of flow field with separation. In the first part it contains theoretical bases of flow field computational modeling with RANS models equations and wall treatment modeling approaches included. There is also flow separation in asymmetric plane diffuser modeling described in the thesis where the most suitable turbulent model and the proper mesh parameters for the successful flow separation modeling should be chosen. Next the chosen turbulent model and parameters verification via flow separation modeling on the asymmetric 3D diffuser mesh. That analysis should ensure if the chosen turbulent model is applicable also for engineering problems. At the end of the thesis there is evaluation if the setup chosen in the thesis is suitable to apply in any practical aeroacoustics problem modeling.

Stolen generation in Australia
Valentová, Zuzana ; Armand, Louis (advisor) ; Kolinská, Klára (referee)
The main theme of this thesis is Australia's "Stolen Generation." This term refers to the Aboriginal and Torres Strait Islander children who were removed by force from their families between the years 1909 - 1969. However, these years are only unofficial numbers and it is known that the removals took place even before and after this period. The aim of this policy was to assimilate the Aboriginal people in order to educate them in the British manner. This policy was an act of cruelty and abuse since the children were brought away from their families and put into state institutions or foster care to suppress their culture. The aim of the thesis is to portray the development of the Aboriginal culture; beginning with the situation prior to British colonization and ending with the current situation in Australia. The thesis analyses the situation during the colonization and after it because the process of colonization caused further changes. It demonstrates the inability of the Indigenous people to assimilate to the new lifestyle. After the colonization, the Aborigines were deprived of their land and their traditional culture. The worst policies were the removals of so-called 'half-caste' children from their families, which were nothing less than forcible removals that were done without any permission from their...
