The goal of this thesis is to improve graphical user interface of Tone Mapping Studio(TMS) program. This program is being developed on the Faculty of Information Technology(FIT), Brno University of Technology (BUT) by doc. Ing. Martin Čadík, PhD. The current program is using framework Qt3 , which is old and not compatible with modern libraries. This program has to be rewritten to support current version Qt5. I will analyze other programs in the area of working with High Dynamic Range (HDR) images and video. Changes for improving the interface will be proposed and UX tests will be done. Second part will consist of comparing plug-ins for converting images to grayscale that already exists in TMS.

The ability of an individual to withstand elevated head-to-toe gravitoinertial (+Gz) forces is determined by the capacity of their body to maintain sufficient head-level arterial pressure. Recent studies have shown a relationship between resting blood-vessel stiffness and an individual’s +Gz-tolerance, although the mechanisms behind this relationship are unclear. The aim of this project is to determine whether or not +Gz-tolerance is affected by a change inresting vasomotor tone. To evaluate this relationship, seven participants were asked to complete a +Gz-tolerance protocol using a human-use centrifugeon two different occasions. On both visits, gradual onset rate (0.1 G.s−1)and rapid onset rate (3.5 G.s−1) tests were done to evaluate the participants+Gz-tolerance. On one of the two visits, prior to the +Gz-tolerance testing,participants performed a 20-min cycle intervention to induce postexercisehypotension, with the aim of temporarily reducing participants’ resting bloodpressure and vasomotor tone. The cycling intervention was successful atinducing postexercise hypotension, as mean arterial pressure was significantlylower on the cycling visit (P<0.05). +Gz-tolerance was significantly lower(P<0.05) on the cycling visit compared with the non-cycling visit for both theGOR and ROR tests (absolute difference of 0.5 G and 0.25 G, respectively).The effect of the type of test on +Gz-tolerance was not influenced by the effectof the cycling intervention (P>0.05). Being the most documented mechanismlinked to postexercise hypotension, sustained vasodilation was assumed tohave occurred. This would have increased distensibility of the affected vessels,explaining the decrease in +Gz-tolerance. The decrease in +Gz-tolerance wassimilar for both tests, indicating that the baroreflex was not affected by thecycling intervention. Assuming that vasodilation occurred, this study showedthat a decrease in resting vasomotor tone decreased +Gz-tolerance, indicatingthe importance of this variable in the relationship between resting blood-vesselstiffness and an individual’s +Gz-tolerance.

This study examined the linkages between marital harmony and conflict and infants' emotional and physiological regulation abilities and developmental status at six- and nine-months of age. Participants included 93 first-time mothers and their infants (43 males, 50 females) from a Mountain West community. Mothers were asked to complete a battery of questionnaires, including a demographic measure and Braiker and Kelly's (1979) marital quality questionnaire. The revised Bayley Scales of Infant Development (BSID II) and Behavior Rating Scales (BRS) 2nd Edition were administered at six- and nine-months to measure infants' mental and motor development status and emotional regulation abilities. Infants' heart rate was also measured at six- and nine-months to measure their physiological regulation abilities. While correlations were found between high levels of marital conflict and infants' emotional regulation abilities at six-months, these correlations were not found at nine-months. However, this study was able to tease apart the direction of affect between marital conflict and infants' emotional and physiological regulation. Based on previous literature, it was hypothesized that marital conflict at six-months would predict infants' regulatory abilities at nine-months. However, the results from this study suggest that infant variables at six-months predict marital quality at nine-months. Specifically, infants' low emotional and physiological regulation abilities at six-months predicts higher levels of marital conflict at nine-months. Overall, these findings present a new perspective and offer new insights into the relationship between marital conflict and infants' regulation abilities. These findings have important implications for understanding the impact that infants' poorer regulation abilities can have on a marriage. Additional research is needed to further investigate the long-term consequences of infants' regulatory abilities on marital functioning and vice versa.

In this study, the Anton Webern's music is considered in two groups: that which was written before Webern adopted the twelve-tone technique, Opp 1-16, and that written in the twelve-tone technique, Opp. 17-31. This division is not intended to represent an attempt at periodization of Webern's music, for the changes of style in Op. 17 are not that significant. But the fact that Webern employed the twelve-tone technique in all the works he wrote after Op. 16 makes this a natural point of division for a study of this sort. Besides the music of Webern, two peripheral areas are included in this study. No attempt has been made at an exhaustive biography of Webern, but facts relative to his life, and impressions about the person are presented. Also, to create a proper perspective for the study of Webern's which existed during the time that Webern lived and composed, is presented.

High dynamic range (HDR) imaging is a rapidly growing field in computer graphics and image processing. It allows capture, storage, processing, and display of photographic information within a scene-referred framework. The HDR imaging pipeline consists of the major steps an HDR image is expected to go through from capture to display. It involves various techniques to create HDR images, pixel encodings and file formats for storage, tone mapping for display on conventional display devices and direct display on HDR capable screens. Each of these stages have important open problems, which need to be addressed for a smoother transition to an HDR imaging pipeline. We addressed some of these important problems such as noise reduction in HDR imagery, preservation of color appearance, validation of tone mapping operators, and image display on HDR monitors. The aim of this thesis is thus, to present our findings and describe the research we have conducted within the framework of optimizing the HDR imaging pipeline.
