Women behavior in road traffic
Gajdůšková, Vendula ; Belák, Michal (referee) ; Bucsuházy, Kateřina (advisor)
This thesis is focused on women's behavior in road traffic, specifically the visual perception of the situation behind the vehicle before initiating, during, and after completing the selected driving maneuvers. Based on the analysis of the current state, experimental measurements were proposed to be conducted in real traffic conditions in Zlín and its surrounding area. The visual perception during the analysis of the situation behind the vehicle, eye movement strategies, and their durations were analyzed. The average fixation durations ranged from 0.28 seconds to 0.47 seconds. The results showed that the longest fixation durations were recorded when stopping before an intersection and the shortest when turning right. The study also revealed differences in eye movement strategies and behavior between men and women. It was shown that women focus more on the situation in front of the vehicle than on the situation behind it. The results of this work can be utilized in the analysis of road crashes and contribute to the improvement of driving school training.

Optimization of preparations for pressing the FRL product
Štrejbar, Vojtěch ; Vetiška, Jan (referee) ; Tůma, Zdeněk (advisor)
The bachelor's thesis deals with optimization of pressing preparations for the production of fuel return line (FRL) in the company Bosch Powertrain s. r. o. The optimization means mainly reducing the risk of damage to FRL components and hoses. An analysis of the pressing preparations used in the production was carried out. Based on the analysis, modifications to existing preparations of semi-automatic stations were recommended. The thesis further focused on new design of preparations on automatic station. The aim of the design was to improve clamping of a FRL component, namely a specific connector. This connector has shape, which makes it difficult to ensure correct clamping. For clamping, it is problematic to meet two requirements, namely preventing change of the connector position during pressing and preventing damage to the edges of the connector. Considering the limiting conditions, several solution variants were designed, and the best variant was selected using evaluation criteria. This variant is further developed, including a 3D model and drawing documentation. The main modification is the new design of the clamping jaws.

Cognitive Biases in Legal Thinking
Zaklaiová, Vanda ; Ondřejek, Pavel (referee)
Cognitive Biases in Legal Thinking Abstract This diploma thesis addresses the phenomenon of cognitive biases in legal thinking, i.e., it connects the latest findings in psychology and behavioural economics with various areas of law. It aims to introduce selected illusions of mind to the reader, especially those most significantly affecting not only judges, forensic experts or attorneys, but also legislators and policy-makers, as well as general public when they come into contact with law. The thesis also presents ways of eliminating the negative influence of biases on law and justice (to the extent possible), and even suggests appropriate use of them for the benefit of the society as a whole. The thesis is therefore a review study, mostly based on the analysis of dozens of empirical studies, which on one hand informs the readers about the errors resulting from the cognitive biases, and on the other hand encourages application of the proposed methods of eliminating the negative impact of errors in readers' own legal practice - or at least encourages them to take the analysed biases into account. The introduction briefly explains why lawyers should take the latest findings in the field of cognitive and behavioural sciences into account. Furthermore, it explains what heuristics and cognitive biases are, and...

Boundary layer transition visualization in aerodynamic tunnel
Holík, Denis ; Trusík, Vojtěch (referee) ; Popela, Robert (advisor)
The purpose of the thesis was to propose and test an imaging method that allows visualization of the transition of a laminar boundary layer to a turbulent one and visualization of laminar boundary layer separation on the side mirror of a car. The beginning of the paper discusses the theoretical foundations associated with boundary layer formation and its evolution under various conditions. Afterwards, a survey of existing imaging methods that allow the display of flow on the surface of bodies was carried out. Of these methods, imaging using a thermal imaging camera was selected on the basis of the specified characteristics. The method using oil film (oilflow) was chosen as a control. Using both methods, experiments were conducted to confirm the suitability of the thermal imaging method for visualizing the transition of a laminar boundary layer to a turbulent boundary layer. The final test revealed the presence of laminar boundary layer separation on the upper cover of the car side mirror. At the end of the thesis, possible errors associated with the two chosen visualization methods were summarized, and ways to incorporate the thermal imaging method into automotive testing were proposed.

Essays in Experimental Economics: Labor Market Discrimination
Jibuti, Daviti ; Filer, Randall (advisor) ; Hamermesh, Daniel S. (referee) ; Deb, Partha (referee)
i Abstract The three chapters in this dissertation use field experiments to examine discrimination in various settings. Chapters I and II use a correspondence testing approach to study discrimination against applicants with visible tattoos in the German labor market. Previous empirical research has documented unfavorable treatment of tattooed applicants on the labor market. This may be because negative stereotypes are still associated with tattooed people, despite the increasing popularity of tattoos. However, the impact of tattoos on employment chances may be different across different occupations. Fictitious applications are sent to online job postings in the banking and IT sector. Otherwise identical applications differ only in the picture attached: in the treatment group the applicants have a visible tattoo. The extent of discrimination is measured by the difference in callback rates. The data indicates that the candidates without visible tattoos have, on average, a 13-percentage point higher callback rate in the banking sector, and in the IT sector applicants with visible tattoos are about 25% less likely to get a callback. In the third chapter we conduct a study of hiring bias on an online platform where we ask participants to make hiring decisions for a mathematically intensive task. Our findings...

Tomeš, Matěj ; Seidl, Jakub (advisor) ; De Bock, Maarten (referee) ; Den Hartog, Daniel J. (referee)
Title: Forward and Backward Modelling of Spectroscopic Diagnostics in Fusion Plasmas Author: Matěj Tomeš Department: Department of Surface and Plasma Science Supervisor: Mgr. Jakub Seidl, Ph.D., Institute of Plasma Physics of the Czech Academy of Sciences Abstract: The thesis primarily focuses on developing forward and backward models for fusion diagnostics. It encompasses the development and application of these models for Thomson scattering, the inference of neon concentrations in JET's divertor and for synchrotron radiation. In the first chapter, the forward model of Thomson scattering designed for Cherab is detailed. This includes the development of a laser module intended for a wide range of applications, primarily to facilitate Thomson scattering simulations. An application example is provided by a comprehensive model of the Thomson scattering diagnostic used at the COMPASS tokamak. The model of the diagnostic is combined with experimentally obtained electron profiles to assess its performance. The second half of the chapter focuses on the development of a backward model for Bayesian inference of temperature profiles from measured Thomson scattering data. The effectiveness of this model is compared to the conventional approach based on least square error optimization, revealing clear advantages of...
