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.

The Tolerance Analysis of Filters with CDTA
Miksl, Jan ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
The bachelor thesis deals with the concept, design, modeling, tolerance and sensitivity analysis of the KHN filter using CDTA. The first part contains theoretical introduction about filters and their general properties. Secondly, the CDTA element, its block structure, schematic symbol as well as its circuit features are defined. Standard KHN filter structure with operational amplifiers is simulated. Results of this simulation are used for comparison with simulations results of CDTA KHN filter structure. The multifunctional CDTA KHN filter structure is simulated using ideal CDTA models, third-level models and models based on professional macromodels of attainable components (AD 844, MAX 435). Then tolerance and sensitivity analyses are explained and described. The following section discusses ways of modifying the structure and design KHN structure with CDTA models 3rd level. In the last chapter the circuit is optimized using PSpice and the attention is focused on achieving the best possible involvement of the typical characteristics of the elements of tolerance. In conclusion, the results of simulations are evaluated, compared the characteristics of circuit before and after optimization, and mention the advantages and disadvantages of filter elements with CDTA.

Analysis, features and applications of available current mode multipliers
Miksl, Jan ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
The diploma thesis deals with analysis, validation, measurement of parameters of the commercially available current multiplies (namely the EL2082 and EL4083) and their applications in practice. Control analysis are carried out in OrCAD PSpice program and compared with values from datasheets. Control analysis are focused on AC and DC characteristics of these active blocks. There are discusses the input impedance, the output impedance, the current gain and the possibility of electronic adjusting. The parameters of the elements were verified by measurements. Proposals for circuit applications (selective circuit, oscillator, frequency filter) with EL2082 and EL4083 are presented and analyzed in the program OrCAD. Three oscillator circuit designs are experimentally tested and the results are compared with the theoretical expectations and simulations in OrCAD. The possibility of electronic control for oscillators is examined. Also the sensitivity and the tolerance analysis are carried out. The constructional details of oscillators are presented at the end of this work.
