Cable-supported pedestrian bridge
Knotek, Jan ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
The subject of this diploma thesis is design a cable-supported pedestrian bridge. Three different variants of the solution were created for the design. For detailed processing, variant no.2 was chosen - a suspended bridge with a pylon in the middle of the span. The main task is the static design of the supporting structure. The model for the lengthways is created in ANSYS. The SCIA engineer was used to solve crosswise. The assessment and dimensioning was done according to the limit state principles and valid standards.

Design of a prestressed slab
Juříček, Lukáš ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
Diploma thesis is focused on the design of prestressed concrete membrane from the lightweight concrete. The concrete membrane is in the interaction with the bearing steel structure, which one is supported. I did only one variant of the solution, which was optimized. The goal of the design was determined the initial state of a membrane and ensure to in the end of design working life was the membrane in the compression state and the cracks couldn’t appear. The structure is modelled in the main (longitudinal) direction as a spatial frame in program ANSYS 17.2. This tool enables to perform analysis of the construction stages. The rheology is calculated manually and supplied to the model as relative strain. The whole structure is checked for ultimate limit state and serviceability limit state according to valid Eurocodes. Transverse direction is modelled by shell elements in program RFEM 5.12. Construction stages and global behaviour of the structure were analysed. The checks have been calculated manually and control in program IDEA StatiCa. The attachments of the thesis are drawings, visualisation and schemes of construction stages.

Political Nepotism
Šebek, Jiří ; Znoj, Milan (advisor) ; Profant, Martin (referee) ; Novotný, Josef (referee)
There is circumstantial and scientific evidence of nepotism in Europe and USA, and among politicians, judges and other elites. Despite this, an access to positions of power in a liberal democracy is restricted in the sense that occupational following in the offices is subject to public scrutiny. There is a conflict between a personal obligation to promote one's kin and a public obligation to promote liberty. This public duty emerges from a duty to allow access to offices of power to those who have the misfortune of not being born as dynastic followers. It is based on John Rawls's original position which is a thought experiment establishing an impartial environment to detect chief principles adjudicating conflicts of moral doctrines, fairly. In it, the condition of impartiality is achieved by means which are found in this dissertation to be excessive. Its blanked ban on biases immolates even those biases which contribute to fairness, despite their partiality. When nepotism is partly considered an expression of altruism, it shows a capacity to increase cohesion, impede free-driving and improve economy. In order to preserve these virtues, an improved condition of impartiality is offered to enhance Rawls's theory and to classify instances of nepotism according to their effects on improving or hampering...
