New gel electrolytes
Sumka, Martin ; Jahn, Michal (referee) ; Sedlaříková, Marie (advisor)
This master´s thesis deals with the properties of gel polymer electrolytes, brief characteristics of other types of electrolytes and materials that are used for preparing polymer electrolytes. The thesis explains the use of the gel electrolytes in practice, the current conduction in the electrolytes and the properties of ionic liquids, and flame retardants. This thesis also focuses on methods of measurement of mechanical properties of gel polymer electrolytes. The practical part is focused on preparation of methacrylate gel electrolytes and their modifications with the use of flame retardant - triethyl phosphate (TEP) and ionic liquid - 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (Emim TFSI). In this part there are evaluations of their potential funcionality (potential window) and specific conductance conductivity using the method LSV (linear sweep voltammetry) and impedance spectroscopy. The practical part also includes a thermal analysis of selected samples by TGA, DTA and EGA methods.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Effect of Dust on Properties of Collagen Materials.
Součková, M. ; Mašková, Ludmila ; Smolík, Jiří
Samples of collagen materials were exposed to dust for two years in depositories, but the total deposition of particles was very small (approx. 0.1 weight percent). For this reason to another samples of collagen materials were dust particles applied using a bag from nonwoven textile. After the artificial ageing of samples the dust was removed mechanically and properties of collagen materials were investigated.\n\n

The effect of moisture in building - causes, consequences, possible solutions
STUDENÁ, Sandra
This bachelor's thesis deals with the issue of humidity in building constructions in terms of modern and historical architecture and its impact on building constructions. In a theoretical part, there are described all symptoms, causes and sources of moisture in buildings, negative effects of moisture for building construction and the most frequent possibilities of research and moisture diagnosis. Next, there are described safeguards against water, dehumidification methods of construction and the possibility of protection of the building against moisture in historic buildings. The second (practical) part of this thesis deals with the exploration of a selected building object. Here is investigated the cause of moisture masonry, on the base of the sampling masonry examines the degree of wall humidity, proposes measures to prevent access of moisture into the building and construction method of building dehumidification.

Palynologie vzorků z vrtu Střeleč (V-800)
Svobodová, Marcela
Borehole V-800 Střeleč was drilled in the area of sand-dominated delta sequences of the UNESCO Geopark “Bohemian Paradise” across the Coniacian/Turonian boundary and reached the lithostratigraphic boundary of the Teplice and Jizera Formations.(Čech, 2009). A relatively well preserved and diversified palynomorph assemblage was ascertained in grey claystones. Marine elements prevailed in all 23 studied samples. The composition of dinoflagellate cysts of Late Turonian age was partly comparable to that found in deposits of the Úpohlavy quarry (Svobodová et al., 2002, Uličný et al., 1996). The preservation of dinocysts and pollen grains in the upper part of the borehole (Coniacian age) was better than the preservation of palynomorphs from the lower part of the borehole (Turonian age). Chitinous linings of microforaminifers were abundant as well as amorphous organic matter. Biostratigraphically important angiosperm pollen of the Normapolles group were more common in sediments of the Coniacian age – Emscheripollis sp., Trudopollis sp., Plicapollis sp., Minorpollis sp.. Oculopollis sp. a.o. Tricolpate reticulate pollen appear rarely in lower part of the borehole.
