Smart Materials for Medical Applications
Kaplán, Martin ; Hájek, Petr (referee) ; Florian, Zdeněk (advisor)
This thesis describes materials which react to external stimuli. These materials are know as Smart materials. The thesis provides an overview of these materials and their use in the field of medicine. A lot of attentions is paid to Nitinol as the most significant representative of Smart materials. The thesis brings a simulation of using shape memory effect of Nitinol staple for bone fracture fixation. This simulation use the method of finite elements for solving and it is done in ANSYS modeling software. The simulation has only demonstrational purpose.

Hybrid turbulence models for strongly swirling flows
Kaplán, Martin ; Štefan, David (referee) ; Rudolf, Pavel (advisor)
The aim of this paper is to investigate using of hybrid turbulence models for strongly swirling flows. The work is focused on the possibility of applying a hybrid SBES model to simulate flow around a hydrofoil. The work further describes the creation of a mesh for the solved domain, the setting of boundary conditions and the setting of the solution for the software FLUENT. The simulation results are compared with experimentally measured values. The work also uses and evaluates data from PIV measurements. The knowledge that the paper brings as part of the results of a research project can be applied in the future in the design of blades of water turbines.

Studies of the K-shell double vacancy production in the electron capture decays of 55Fe, 54Mn and 65Zn using hybrid pixel detectors
Kaplan, Martin ; Bergmann, Benedikt (advisor) ; Valenta, Stanislav (referee)
The presented thesis provides an experimental study of the K-shell double vacancy production in the electron capture decays of 55 Fe, 54 Mn, 65 Zn using a pair of Timepix3 detectors. Measured data are preprocessed and explored. The methodology for the cal- culation of the probability of K-shell double vacancy production in 55 Fe and 54 Mn is developed. Therefore, an extensive amount of signal and background processes were con- sidered during the development of the methodology. The measurement setup is defined and optimized in the Allpix2 framework for a simulation of detection efficiencies of par- ticles participating in the signal and background processes. The probability of K-shell double vacancy creation in the electron capture decay of 55 Fe was measured to be PKK = (1.406 ± 0.05) × 10−4 with a systematic error of ∆sys(PKK) =+0.030 −0.034 ×10−4 . The value of PKK for the electron capture decay of 54 Mn found to be PKK = (3.93 ± 0.44) × 10−4 with a systematic error of ∆sys(PKK) =+0.25 −1.11 ×10−4 . Resulting probabilities for K-shell double vacancy production in 55 Fe and 54 Mn are in agreement with the latest results. 1

Genetically modified organisms and legal regulation of their use
Kaplán, Martin ; Žákovská, Karolina (advisor) ; Franková, Martina (referee)
The purpose of this paper is to analyse legal regulation of genetically modified organisms ("GMO"). This work consists of seven chapters and focuses especially on differences in regulations of the United States of America ("USA") and European Union ("EU"). While the USA consider GMO equal to other products and have no GMO specific legal norms, the EU regulates GMOs with directives and regulations which set GMO apart from other products. Conclusions are being drawn in last chapter. It is suggested, that the protective and economic approach to the GMOs should be ballanced out on the international law scene, so that the development of biotechnology is not slowed down too much, while safety to human health and environment is guaranteed.

Use of kinematic-constrained decays in the alignment of the Belle II detector.
Kaplan, Martin ; Kodyš, Peter (advisor) ; Kvasnička, Peter (referee)
This thesis is a Monte Carlo study of several distinct samples and some of their combinations for track-based alignment of tracking detectors at the Belle II experiment. Simultaneous alignment of drift chamber layers, vertex detector sensors including their deformation parameters and vertex detector half-shells is performed using a set of linear constraints. Samples of muon tracks from cosmic rays, muon pairs from the e+ e− → µ+ µ− process with and without the inter- action point vertex constraint and muon pairs from the kinematic-constrained J/Ψ → µ+ µ− decay are studied. Performance of certain combinations of sam- ples in the alignment procedure of the tracking detectors is analyzed. One combination of samples is identified as a suitable sample for the alignment of the real detector, which started its operation in spring 2019 and thus the results of this thesis present a first comprehensive analysis of systematic and statistical errors associated with a realistic scenario of the Belle II detector. 1
