Markets and Electricity Trading from Renewable Sources in EU
Pěcha, Jiří ; Čambala, Petr (referee) ; Macháček, Jan (advisor)
The submitted diploma thesis describes particular types of European energetic exchanges, focuses in depth on principles market in Czech Republic and studies the price development on spot and futures markets. The main idea of this work is to focus on renewable energy sources (RES) and their influence on energetic markets. At first, operational and reliability properties of RES are explained and then their development support is analyzed. Last chapters focus on how the power grid is impacted by RES that are hardly predictable source with local production characteristic. There are also outlined problems originating from irregular production that are linked to a surplus of electric energy, but also on energy shortage caused by bad weather. These problems influence international commerce and reduce the capacity of cross-border profiles.

Use of meteorology and historical comparisons atmospheric conditions for yachting and water sports
Hájek, Petr ; Jindra, Matouš (advisor) ; Dvorský, Jaroslav (referee)
Title: Use of meteorology and historicalcomparisons atmospheric conditions for yachting and water. Objectives: At work I use two basic methods of research. The method of content analysis and interview. Content analysis, I get the information for the theoretical part of the work, using professional sailing and meteorological publications. Furthermore, the method of non-standardized interview, which I took while visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I have discussed his work with Dr.. Joseph Brechler, PhD. Furthermore, with top windsurfing in the Black foothills and Nechranické dam. Methods: At work I used as a basic research methods method of content analysis and interview. Content analysis, I gained information for the theoretical part, the professional sailing and meteorological publications that deal with the issue. Non-standardized interview method I used when visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I discuss my work with Dr.. Joseph Brechler, PhD., Then Ing. Ružbatský in the foothills of the Black and F.Kasík of Nechranice. For wider acquaintance with the issues I was trying to get other sources of information on various internet portals related to...

Evaluation of landscape changes in the Krkonoše Mountains national park using remote sensing and landscape metrics
Karvánek, Matouš ; Kupková, Lucie (advisor) ; Štych, Přemysl (referee)
The aim of this bachelor thesis was to analyse of land cover and landscape state in the Krkonoše Mountains National Park between 1999 and 2007, using supervised classification and landscape metrics calculation. After the classification (Maximum likelihood algorithm) based on legend with 8 categories (5 types of vegetation, arable land, water areas, other areas), overlay analysis was performed by change detection and map sof land cover state and changes were created. The changes of the landscape and landscape components state were evaluated using landscpae metrics in software Fragstats. The overall accuracy for the image from 1999 was 81,50% and for the image from 2007 83,25%. Based on results i tis possible to conclude, that the area of forests increased and as fr the species composition the share of deciduous forests increased during this time period. Shift to a less diverse landscape was recorded based on landscape metrics evaluation. Coniferous forests comprised the landscape matrix in 1999 and also in 2007. Key words: supervised classification, land cover, landscape metrics, SPOT, FRAGSTATS, The Krkonoše Mountains National Park

Application meteorology and historical comparison between weather(meteorological) conditions for yachting and water sports
Hájek, Petr ; Jindra, Matouš (advisor) ; Dvorský, Jaroslav (referee)
Title: Application meteorology and historical comparison between weather(meteorological) conditions for yachting and water sports Objectives: To be making maps about windsurfing sports within specific locations. Prove or disprove scientific research about weather conditions changing from 1980 to 2014 years. It's about yachting and water sports at the same locations. Methods: Diploma is descriptive and analytic article. There are methods like research, selections of sources, analysis of information and final synthesis everything knowledge. Results: Description four water ponds for water sports and analytic work with database about weather conditions in the studying locations. Keywords: Meteorology, wind, spot, water sport, yachting.

Assessments of forest damage using satellite and LIDAR data
Lihanová, Kristýna ; Štych, Přemysl (advisor) ; Bartaloš, Tomáš (referee)
Assessment of forest damage using satellite and lidar data Abstract The main objective of this thesis is to create a methodical procedure used for the evaluation of forest damage in the chosen area of the National Park Sumava, Czech Republic. In this work were combined the multispectral satellite data and data of airborne laser scanning. The forests in this area are heavily damaged mainly due to bark beetle outbreak. You can find here as healthy so damaged forests. Based on this methodology will be differentiated greater number of classes than I found in the literature. In this work was used pansharpened multispectral image SPOT, multispectral image Landsat and airborne laser scanning data with low density points. Another task was to get height information from ALS data in the form of grid. Forest stands were classified using object-oriented classification, which included at first segmentation and then creation of classification base. In classification entered spectral information and height information obtained from the ALS data. Forests were classified into 5 classes and accuracy of both classifications was evaluated using the error matrix and kappa coefficient. SPOT image classification reached kappa coefficient of 68,5 % and Landsat image classification reached kappa coefficient of 72,3 %. From the...
