Dielectric Elastomers
Fiala, Vojtěch ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The thesis contains extensive theoretical information and consist of several parts, where in the first part of the text are specified mainly general knowledges about electroactive polymers (EAP) and their different types. In this part, the reader should get a basic view of the issues and realize sense of these materials. The following text is more specifically addressed on one group of electrical EAPs called dielectric elastomers (DE). Introduction to DE is conceived comprehensively, that means from general information and principles of function to specific and deeper information. For example in the text are included information about individual materials and differences between them, particular application areas, etc. Above all, the text focuses on the fields of sensorics and energy generation.

Analysis of Business Performance Factors
Janková, Ivana ; Fiala, Vojtěch (referee) ; Režňáková, Mária (advisor)
This graduation theses analyses intercompany comparisons using one-dimensional and multi-dimensional methods. It focuses on enterprises actuating in terms of a subsegment of national economy – building industry. Factors that influence the performance of companies most in this field will be selected by using correlation coefficient. Its economic development during the years and also characteristics of the industry will be described in details.

Database of Czechoslovakian Television Broadcasting
Fiala, Vojtěch ; Firc, Anton (referee) ; Rozman, Jaroslav (advisor)
This thesis describes the process of creating a Czechoslovak Television broadcasting database using optical character recognition technology. The aim of the work is to create a database that can be accessed through a simple web interface, in which it will be possible to browse individual shows, their descriptions and to search among the shows. Searching will also be possible by people involved in the shows. Tesseract was used as the optical character recognition engine, obtained shows were entered into a SQLite database and Flask was used for the web interface. Scanned pages of Týdeník Československé televize were used as source materials and the years from 1966 to 1992 were processed. The results of the work give users an insight into the history of television broadcasting in Czechoslovakia and can be used, for example, for the purposes of historians.

Back-bone deformation analysis using modern sensors
Fiala, Vojtěch ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This bachelor thesis summarizes the knowledge of the medical and technical field related to the project. In the medical section, there are mainly described areas of kinesiology and medicine related to the causes and risk factors leading to problems and diseases of the spine. In addition to the description of the disease, there are also presented the diagnostic solutions and treatment. The content of the medical part of the thesis is also a look at some commercially available products dealing also with postural problems. Part of the technical part is acquaintance with the Arduino platform and the components that are included in the practical part of the bachelor thesis. In the technical part, the area of motion sensors such as accelerometers, IMU sensors and gyroscopes are also described in more detail. Especially there is described IMU MPU-6050, which is used in this project. Further, the thesis describes the procedure in the practical part of the project, including the design of the positioning of the sensors with the positions in which the data are measured, as well as the design of the assembly and its optimization. Subsequently, the final appearance of the device, including the method of attachment on the body, and the measurement results are shown. Results are later commented and discussed. The final part of the thesis is the final summary of the results achieved and the reflections on the possibilities of further work or further adjustments and modifications of the existing equipment.

Preferences for markers of health status in humans
Jíchová, Františka ; Havlíček, Jan (advisor) ; Fiala, Vojtěch (referee)
Several evolutionary hypotheses suggest that different organisms have evolved systematic preferences for markers of mate health. These markers may provide clues to an individual's immunocompetence, current health status, and health history. Correct recognition of good health helps to select a quality partner who can offer advantages such as good genetic qualities that can be passed on to offspring, can participate more effectively in the care of offspring, and thus does not put the individual at risk of infection. Awareness of these markers may be important not only in mate choice but also in other social interactions in which it is important mainly to correctly estimate current health and possibly avoid interaction with an infectious individual. Preference for markers of health in humans may be based, for example, on visual cues in the face, such as color, sexual dimorphism, skin texture, or an assessment of overall stature. Markers may also be olfactory, where an unattractive odor may indicate the presence of a potential disease. Last but not least, there are acoustic markers. However, the interaction of the manifestations of each modality may also be important. The aim of my bachelor thesis is to provide a theoretical overview of the association of current health, immunocompetence and health...

Cross-cultural perception of sexual dimorphism in human face
Fiala, Vojtěch ; Kleisner, Karel (advisor) ; Králík, Miroslav (referee) ; Lobmaier, Janek Simon (referee)
Evolutionary psychology supposes that human behaviour consists of adaptive tools, functional and mutually intertwined, that help an individual to survive and reproduce. Human proneness to ascribe psychological characteristics, based on an individual's facial features, may present such an adaptive tool. Facial sex-typicality, the individual representation of facial features regarding a given sex (male/female), affects other ascribed characteristics. Potential functional associations between sexually dimorphic facial structure, perceived sex-typicality, and physiological and behavioural correlates are the very topic of this thesis. Following theoretical background, there are three studies listed as 'Published studies' (Study 1-3). Study 4, the submitted manuscript, has not been peer-reviewed yet. Study 5, already published, is listed as 'Appendix'. Study 1 (Fiala et al., 2021) compares the effects of perceived 'sex-typicality' and measured sexual shape dimorphism on ratings of attractiveness across five distant countries. Rating participants and stimuli faces were always from the same country. Whilst perceived female femininity is preferred across cultures, analysis of preference of perceived male masculinity and both-sex measured sex-typicality reveals cross-cultural discrepancies. Study 2 (Fiala et...

Cross-cultural perception of attractiveness and its correlates: the role of visual modalities
Fiala, Vojtěch ; Kleisner, Karel (advisor) ; Třebický, Vít (referee)
This work reviews the literature on the topic of intercultural perception of human attractiveness with special focus on recent videostimuli-using research. The first section introduces several basic perspectives on ecological-evolutionary view of attractiveness. The next section deals with intercultural differences in attractiveness perception dicussing possible explanations of these differences. The third chapter focuses on faces of people of cross-culture origin and usage of composite stimuli and artificially manipulated stimuli in inter-cultural research. The fourth chapter examines the usage of videostimuli in attractiveness research. I also add information about intercultural usage of videostimuli as far as these are available. Finally, I discuss a possible source of result ambiguity and highlight the potential use of videostimuli in intercultural research of attractiveness perception. Keywords Attractiveness, intercultural perception, videostimuli, cross-culture origin, composite images, averageness, masculinity, feminity
