Application of modern cluster analysis in a market segmentation
JOANIDIS, Filip
This thesis aims to describe the theoretical principles of customer segmentation using modern methods of cluster analysis and their practical verification in a commercial environment of utility company. The theoretical part of the thesis describes the principles of clustering analysis using K-means algorithm and hierarchical clustering algorithms. The SW support chapter deals with the possibilities of R, Rapid Miner and KXEN software tools. For the purpose of data processing the theoretical part describes SEMMA, 5A and CRISP methodologies. The practical part is focused on the analysis of homogeneity/heterogeneity of the energy market in the household segment in the utility company EON. Using data from company´s customer system, available external data and programming language R a hierarchical cluster analysis is processed. Through the analysis of gained clusters there are identified the main characteristics of particular clusters which are consequently examined from marketing usage perspectives.

Who is buying luxury Czech fashion?
Hříchová, Monika ; Špecián, Petr (advisor) ; Máslo, Lukáš (referee)
This bachelor thesis is looking for the determinants of buying luxury fashion by Czech designers. The main conclusions of worldwide studies are examined based on data provided by the designers. Customer information were provided by companies Veršatyl and One Life. Qualitative data from the Veršatyl brand are examined using descriptive statistics. Data resulting from the purchase statistics from the One Life brand are converted into numerical values and investigated using regression analysis. The most important determinants when buying luxury Czech fashion include the quality of the product and its manufacturing.

Implementation methodology of open source ERP in SME
Polák, Tomáš ; Gála, Libor (advisor) ; Lieb, Dušan (referee)
This paper deals with the implementation of open source ERP systems in the area of small and medium-sized enterprises. The main objective of this work is to define an open source ERP implementation methodology, suitable for small and medium enterprises. This objec-tive is fulfilled partially by defining of manifesto, as way of thinking about this area and analysis of current state of available implementation methodologies. Newly described met-hodology is then verified by a case study. The main contribution of this work is the defini-tion of implementation methodology for open source ERP systems in area of SME focusing on frequently occurring insufficiencies and leading to successful deployment of company IS.

Quality assurance IMRT plans
LOŠKOVÁ, Michaela
We may regard the Intensity-Modulated Radiation Therapy (IMRT) as a break-through and progress concerning the treatment of oncogenous diseases. In practice, this new method experienced an extensive development as early as at the end of 1990s. At the present time, the IMRT is a medical treatment used in an increasingly frequent manner. It concerns predominantly such oncogenous diseases, the treatment of which based on the above-mentioned method is applicable due to the localization of the disease. The IMRT enables a more effective distribution of a dose in the target volume than in case of the conventional radiotherapy. It is also possible to realize maximum treatment of the surrounding healthy tissues. For the purpose of clinical use of the IMRT, however, it is necessary to verify the correspondence between the dose planned and the dose actually realized in the target volume. From the large quantity of correspondence verification methods available, I decided to select the three following ones to be covered in this paper: - portal dosimetry method - measurement using special phantom - measurement using 2D filed of the Seven29 detectors. The goal of my work was to compare these three methods of verification of the IMRT plans and in addition, to verify the applicability of the 3% tolerance criterion for all the above-mentioned methods of verification. The portal dosimetry method is applicable for verification of fluency; it is fully sufficient and not time-consuming for the purpose of clinical use. The measurement using 2D field provides for sufficiently accurate information on a dose{\crq}s distribution in the modulated field, however, it is more time-consuming and the measuring device is not integrated in the system of the radiation apparatus. Verification using special phantom is considerably time-consuming and it provides for information on a dose{\crq}s distribution in a small quantity of points. The DD=3% criterion I selected is applicable to all three methods with the exception of areas with extensive modulation of the dose and areas on the verge of the field.

Volatility of Euro: Trends and Modelling
Böhm, Petr ; Hanousek, Jan (referee) ; Kočenda, Evžen (advisor)
The main objective of this work is to model volatility of Euro to Czech Koruna exchange rate between 1.1.1999 and 30.12.2005 and investigate changes in its behaviour. In order to achieve this we search for structural breaks in exchange rate time series. We model the conditional variance with ARCH model (autoregressive conditional heteroscedasticity) between particular break points. Our findings are that since year 2002 volatility of Euro to Koruna exchange rate has been decreasing. This conclusion is confirmed by measuring historic volatility by using month average and daily observations. This may has been caused by changing monetary policy, more precisely by adopting new regime of maintaining monetary stability - implicit inflation targeting.
