Design of two-axis linear measuring device for railroad axles pressing
Mlynář, Vojtěch ; Vejlupek, Josef (referee) ; Brablc, Martin (advisor)
The main goal of this bachelor's thesis is the design of the device capable of measuring the distance between railroad wheelset elements during pressing. The research part presents the parameters of the wheelset press and the existing solutions to the problem. Additionally, distance-measuring sensors, motor sizing methods, and sensitivity analysis methods are described. The third chapter outlines the design process, beginning with early conceptions, their analysis, and leading into the final design.

Verification of nonlinear material models
Holada, Jiří ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
The thesis deals with the verification of nonlinear materials during a dynamic test. The reinforced concrete beam is subjected to an impact load. The deterministic finite element model will be developed using several nonlinear material models. The last part describes the sensitivity analysis with MOP (Metamodel Optimal Prognosis).

London Eye
Hušek, Martin ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Performance of static analysis of the London Eye structure is the subject of this diploma thesis. First chapters of the thesis analyses overview of realized structures of the Ferris wheel. The main part of the thesis analyses the London Eye structure itself. Specifically are described response analyses, sensitivity analyses, analyses of ultimate limit state and serviceability, stress analyses, analyses of fatigue stress and lifetime analyses. The thesis describes among static analysis also a design of dynamic vibration absorbers. The results of each analysis are evaluated in the final chapters.

Sensitivity analysis of stability problems of steel structures
Valeš, Jan ; Vičan,, Josef (referee) ; Kučerová,, Anna (referee) ; Melcher, Jindřich (referee) ; Kala, Zdeněk (advisor)
The doctoral thesis is focused on evaluation of global sensitivity analysis of load-carrying capacity of steel hot-rolled beams. These beams are subjected to lateral-torsional buckling, weak axis buckling and strong axis buckling. Very comprehensive computational models which were both geometrically and materially nonlinear were created in Ansys software using solid finite elements to calculate the load-carrying capacity. The computational models allowed modelling of random initial imperfections such as initial curvature, deviations of cross-section dimensions and steel properties. Sensitivity analysis quantified their influence on the load-carrying capacity. Simulation runs of random imperfections were generated using the Latin Hypercube Sampling method. Since the evaluation of sensitivity analysis of load-carrying capacity of all finite element models would cost an extreme amount of computer time, the thesis aimed at developing a meta-model (also known as surrogate model) based on approximation of FEM model. The approximation polynomial then facilitated the evaluation of sensitivity indices using a high number of simulation runs. At the end, the relationships between the slenderness and the first and second-order sensitivity indices are plotted in graphs. Those random input imperfections that influence the variability of load-carrying capacity the most are pointed out.

Economic Evaluation of Public Investment Project
Balogová, Kristina ; Vorlíčková, Petra (referee) ; Hromádka, Vít (advisor)
This thesis deals with the economic evaluation of optimalization of transport infrastructure. Aim of the thesis is to define problematics of economical evaluation of public investment projects and It’s specifics. In analytical part It describes theme of public sector, project life cycle, cost output methods and transport infrastructure evaluation. In the practical part, the project is analysed in the original variant and in case of project suspension for one year. Furthermore, there are perfomed evaluation analyses by sensitivity and quantitative analyzes for both variants.
