Flood monitoring using satellite radar data for different land cover categories
Rauch, Tomáš ; Kolář, Jan (advisor) ; Brodský, Lukáš (referee)
The aim of this thesis is to find method for flood monitoring from radar images. The thesis deals with flood in general and with organization of flood protection. There are described principles of radar sensors. There is also summary of satellites with their parameters. Next part of the thesis describes interaction between radar beam and different types of surface. Theoretical part is closed by overview of the existing methods for flood monitoring. In the practical part there is method for flood monitoring applied to areas affected by flood. The process is based on the classification of the radar image. Using classification and digital elevation model is drawn boundary of flooded area. The result boundaries are compared with the existing maximal flooded areas.

Fenomen of the Culture Shock in Internet Communities
Rauch, Tomáš ; Řehořová, Irena (advisor) ; Brejcha, Jan (referee)
The diploma thesis deals with questions of the culture shock in the internet environment. The aim of the work is to speci fy the problems of the on-l ine culture shock and to create the general view on it. In the fi rst part of my thesis the cyberspace, culture shock and communi ty in the on-line envi ronment are defined. The possibilities and particulari ties of the cyberspace functioning are described from di fferent points of views. The cul ture shock and its form in the on-l ine environment are characterized from anthropological and psychological aspects. At the end of the first part of my thesis the behavior of participants in the on-line communities is described and explained. The second part of my thesis is dedicated to impacts of the culture shock on the internet envi ronment . The standard participant of the Czech internet was defined and therefore certain phenomena were possible to generalize. Possibilities for of the culture shock valuation by di fferent measurements were presented and general standards for its identi fication in the on-line environment were determined. The cont ribution of my thesis is the synthesis of di fferent points of view on the so far unmapped culture shock phenomenon in the internet envi ronment.

Jašek, Pavel ; Novotný, Ota (advisor) ; Rauch, Tomáš (referee)
This topic of this work is web analytics and customer knowledge methods that help small and medium sized businesses for decision support and are intended to yield higher e-commerce results. The main purpose of this thesis is to design and verify possible uses of advanced web analytics methods in a customer-oriented small business. The theoretical part conducts research into the current state of the web analytics industry. The conditions of small and medium enterprises are described and suitable web analytics tools are compared. Several web analytics maturity models are discussed. The practical part of the thesis states specific recommendations obtained from the pilot project for the company Baushop s.r.o. The project consists of a business analysis and use of analytics tools for optimizing internet campaigns and improving customer service. Specific data analysis methods are discussed and all supportive data are provided.
