Evaluation of suburbanization in Prague's hinterland - influence on landuse and on territory function.
Bromová, Petra ; Kupková, Lucie (advisor) ; Potůčková, Markéta (referee)
Evaluation of suburbanization in Prague's hinterland - influence on landuse and on territory function The main goals of this thesis are to describe land use changes in three time periods in cadastral units Dobřejovice, Modletice and Jažlovice situated in Prague's hinterland, to evaluate their influence on the territory function and to create a database of commercial objects in this area. There is a theme introduction in the first part. Furthermore, the thesis describes methods used for the data processing. The main part of the thesis is focused on the characteristic of the area of interest and describes the detected land use and territory function changes based on spatial overlays of time series of very high- resolution image data. The outputs of this work are maps of land use in 1994, 2004 a 2007, maps of land use changes in the particular time periods and the database of the commercial objects with their utilization purpose.

Analysis of forest canopy density based on textural features of hight resolution imagery and airborne laser scanning data
Bromová, Petra ; Potůčková, Markéta (advisor) ; Hájek, Filip (referee)
Analysis of forest canopy density based on textural features of high resolution imagery and airborne laser scanning data Abstract The objective of this thesis is to assess the forest canopy density in the Šumava Mountains, Czech Republic. The spruce forests in this area have been suffering from the bark beetle outbreak for almost 20 years resulting in a mixture of dead and young trees, mature forest stands and peat bogs. The canopy density was evaluated using a very high spatial resolution panchromatic imagery and low point density LiDAR, combined with an object oriented approach. The classification based on three GLCM texture measures (contrast, entropy and correlation), which were derived from the image objects, resulted in a kappa index of accuracy of 0.45. Adding the information from the LiDAR data, the accuracy of the classification improved up to 0.95.

Cross-border cooperation in the Czech - Bavarian border area on the concrete example of the Šumava National Park/Bavarian Forest
BROMOVÁ, Pavlína
The subject of the final thesis is to introduce Czech and German cooperation, especially between regions Bavaria and South Bohemia. The unions and organizations that support this cooperation are also introduced there. The thesis deals with legal normatives, which regulate this interaction. The next chapter is a summary of all euroregions in Czech and German borders. Important part of thesis is the chapter about Euroregion Šumava Bavarian forest Mühlviertel, where is solved Czech-Bavaria part of region, mainly. No less important chapter deals with partnership and financing of National park Šumava and Bavarian forest. The thesis presents concrete projects of this cooperation as well. Common plans and aims by 2020 are mentioned there. The final chapter provides an overview of development of projects focus as well as future progression of these two national parks, through Pavel Bečka, coordinator of Czech-German cooperation in National park Šumava.

Wavelet Based Feature Extraction for Clustering of Be Stars
Bromová, P. ; Škoda, Petr ; Zendulka, J.
The goal of our work is to create a feature extraction method for classification of Be stars. Be stars are characterized by prominent emission lines in their spectrum. We focus on the automated classification of Be stars based on typical shapes of their emission lines. We aim to design a reduced, specific set of features characterizing and discriminating the shapes of Be lines. In this paper, we present a feature extraction method based on the wavelet transform and its power spectrum. Both the discrete and continuous wavelet transform are used. Different feature vectors are created and compared on clustering of Be stars spectra from the archive of the Astronomical Institute of the Academy of Sciences of the Czech Republic. The clustering is performed using the kmeans algorithm. The results of our method are promising and encouraging to more detailed analysis.

Beta-lactamase positive Haemophilus influenzae in children
BROMOVÁ, Pavla
This Bachelor thesis, called {\crqq}Beta-lactamase Positive Haemophilus influenzae in Children`` deals with the basic properties and current occurrence of the bacteria Haemophilus influenzae, and also with the occurrence or other hemofils (Haemophilus species) in children, which occurred in the biological material sent to the microbiological laboratory- Laboma s.r.o. in České Budějovice, where some of them were producers of {$\beta$}-lactamase. The occurrence of these enzymes might be a serious problem for the right choice of antibiotics for the treatment of diseases caused by these hemofils. The essential objective was to collect and assess all data about {$\beta$}-lactamase positive hemofils in the material from airways of children from birth to 15 years of age and with a certain numbers of diagnoses in the aforementioned microbiological laboratory. The data for my thesis was collected in the second half of 2008 and first half of 2009 and was later statistically processed into graphic figures and charts in the form of results. I have also learned to use an easy and used diagnostic method for the verification of {$\beta$}-lactamase ({$\beta$}-LACTAstrip test), during which the color was changed in the zone of the indicator paper if {$\beta$}-lactamase was present. I have also visited pediatricians, who co-operate with this laboratory. They were willing to reply to four questions in my questionnaire. The main objective of these questions was to focus on the treatment of ill children whose biological material from upper airways shows present {$\beta$}-lactamase positive hemofils. From the collected data I managed to reject hypothesis No. 1 by calculating the average relative quantity from the total occurrence of hemofils producing {$\beta$}-lactamase, and I have found that the production of these enzymes is lower by 50 %. Then, I confirmed hypothesis No. 2 that more common producers of {$\beta$}-lactamase are other hemofils (H. species) than H. influenzae. From replies provided by pediatricians, I found out that all of these pediatricians take the presence of {$\beta$}-lactamase into consideration when they chose antibiotics and this confirmed hypothesis No. 3. This Bachelor thesis can be used as an argument for pediatricians to take into consideration the presence of {$\beta$}-lactamase in the biological material of producers, when they choose antibiotics.
