Hydromorphological survey and identification of reference status of the Jizera River
Tomšová, Zuzana ; Matoušková, Milada (advisor) ; Ferbar, Petr (referee)
Long-term and intensive human use of watercourses has led to their considerable degradation. Recently, there has been an effort to improve the ecological status of aquatic ecosystems, based on studies of hydromorphological characteristics of natural watercourses and identification of reference conditions. The aim of this thesis was the hydromorphological survey and an identification of reference conditions of the Jizera River. The selection of sites suitable for identification of reference status was based on pre-set criteria determined on remote sensing data, which eliminated significant anthropogenic impacts on the channel and floodplain. The survey using River Habitat Survey (Environmental Agency, 2003), Hydroecological Monitoring (Langhammer et al., 2014) and REFCON (Šmerousová a Matoušková, 2014a) methods was conducted in selected sites. Sites where hydromorphological conditions correspond with very good class, according to Hydroecological Monitoring, were used for identification of the type-specific reference conditions. Physico-chemical characteristics according to ČSN 757221 (1998) and Rosendorf et al. (2011) and the biological quality element macroinvertebrates according to Opatřilová et al. (2011) were also evaluated. Physico-chemical characteristics reached class I - II (ČSN, 1998) and...

These conversions are transformation of regular expressions to finite automata (FA), remove epsilon rules from FA and determinization FA. The goal was implement demonstration of these transformations in an application. In this thesis I document development of this application. This application was programmed in language C++ using graphic library Qt 5. The application was developed in an operating system (OS) Linux and tested in OS Microsoft Windows 7. All these conversions are implemented. The application is user-friendly, intuitive and functional. The application was not tested on a wider sample of students. As the main benefit, the application can help students of formal languages and finite automata better understand this theory using didactical examples. Source codes of this project (regularConvertor) are available online on Github server.

In this technical report theoretical knowledge related to this topic is described as well as the implementation process of a server system and client side application. Part of this thesis is dedicated to testing of the system and in the final part the potential for future development is drafted.
