Changes in sexual disgust sensitivity during women's reproductive period
Šeda, Jan ; Kaňková, Šárka (advisor) ; Landová, Eva (referee)
Disgust is one of the basic human emotions with an adaptive function, which is primarily to avoid potential transmission of pathogens. One of its components is also sexual disgust, which should serve as a protection against suboptimal sexual behaviour and help in choosing the right sexual partner. The female reproductive period is accompanied by many physiological and psychological changes, which may result in changes in the level of disgust sensitivity. The aim of this study was to track these changes in the still understudied domain of sexual disgust, particularly during pregnancy and postpartum period, but also in non-pregnant women in relation to changes during the menstrual cycle. In line with the proposed hypotheses, higher levels of sexual disgust were observed in women in the first trimester of pregnancy compared to non-pregnant, childless women, which may be related both to the protection of mother and child against possible harm, especially due to infections, or to protection against unpleasant experiences during sex, which may be caused by physical and psychological changes during pregnancy. No statistically significant differences were observed in the degree of sexual disgust in relation to the phases of the menstrual cycle. The results of the longitudinal study showed significant...
Sexual disgust in an evolutionary perspective
Šeda, Jan ; Kaňková, Šárka (advisor) ; Kuncová, Lucie (referee)
Disgust is one of the basic human emotions, its purpose being protection of individuals from situations that could potentially harm them. Disgust can also play a part in many mental disorders. One of the domains of disgust is sexual disgust, which allows an individual to choose the optimal sexual partner and to distance themselves from other individuals who exhibit inappropriate sexual behavior. The sexual disgust sensitivity is influenced by a range of individual factors, such as political orientation, religion, culture and social norms, personality differences, preferred reproductive strategies and gender. Higher average rate of sexual disgust has been observed in women than in men, which is related to their different sexual and social lives. Disgust also plays an important role in prejudice against homosexuals. Keywords: sexual disgust, mating strategies, homosexuality, basic emotions, adaptive behavior
Algorithmic Trading Using Artificial Neural Networks
Šeda, Jan ; Pešán, Jan (referee) ; Szőke, Igor (advisor)
The capability to be able to determine the future progression on the worlds stock exchange is an important issue, which has become discernible in the last decades. An important role of this progression lies within the fast advancements in computerized technology.Aforementioned document describes a mechanism used for prediction of the future price of a certain stock. The strategy of trading is build upon this mechanism, and the core of this prediction system is an artificial neural network. Inputs used in this network are indicators derived from technical analysis. This trading system was implemented into historical trades and successfully tested.

Road Recognition for Visual Navigation of Mobile Robot
Šeda, Jan ; Orság, Filip (referee) ; Marvan, Aleš (advisor)
In recent years, a significant amount of attention has been given to the development of robust road detection algorithms using color monocular vision. Artificial neural networks are often used in order to deal with this complex issue because of their ability to find complex relationships between inputs and outputs. However, the essential task is to choose suitable features extracted from input visual data. In this thesis, the proposed combination of extracted features aims at the problem of robust road detection. The adaptation ability of neural network is also utilized to overcome the difficulties with variable road texture and shadows. Several experiments have been conducted to verify the presented approach.
Heart rate meter
Šeda, Jan ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The aim of the Bachelor thesis is summary of pulse measurement facilities. Heart pulse has been one of the basic measurable quantity in medical science for thousands of years. The basic quality of the given value is accuracy. The analyse of necessity of accuracy in methods for medical practice and diagnostic is the second point of the thesis. The third and most crucial point is heart pulse meter itself – it will be described in terms of mechanics, electrics and software. System based on optical measurement has been chosen in semestral project. Furthermore, accuracy of designed meter will be tested.
Extracting of the optic disc in optical coherence tomography images
Šeda, Jan ; Harabiš, Vratislav (referee) ; Kolář, Radim (advisor)
The main target of this work is a design of the program for border localization of the optic disc in OCT data. Part of this program is also localization of the „optic cup“ and calculation of several values that characterize optic disc. The work is also dealing with a description of the optical coherence tomography principle which is used in ophthalmology. One chapter describes some published methods of optic cup localization. Success of the program and its comparison with OCT Zeiss Stratus 3000 is evaluated at the end of the work.
