The light-curve solution of an eclipsing binary
Procházka, Ondřej ; Zasche, Petr (advisor) ; Wolf, Marek (referee)
The main aim of this work was the first detailed analysis of an eclipsing binary system V641 Aur. The complete light curve of this binary was obtained in three photometric filters, which were analyzed with the program PHOEBE. It is a double star with the orbital period of about 0.50487 day, whose both components are rather similar. Their individual spectral types are probably F6 and F8 (according to the temperatures), or F6 and F6 (as derived from masses). Both are orbiting on a circular orbit and despite their short period the system is a detached one and both components are still located on the main sequence. Moreover, thanks to the asymmetry of the light curve there was discovered a spot on the surface of the primary component, and the third light was not detected. For more detailed analysis higher accuracy of photometry and spectroscopy data are required.

New media and internet marketing via an example of social networks
Vítková, Olga ; Čurda, Pavel (referee) ; Švelch, Jaroslav (advisor)
The diploma thesis, addressing the topic of New media and internet marketing via an example of social networks, deals with the possibilities of practical marketing that these new media offer. The work deals also with the characteristics of these new meadia and this kind of a wider social context. The whole work thus stands on three pillars - the new media and technologies, the new media and social activities and, last but not least, the internet marketing and the referring case study. The characteristics of new media mark several whole new possibilities and opportunities for the marketing activities. With the dawn of new media, marketing grows with the changes of its qualitaty, the society has to learn how to adapt to these conditions and to turn them to its own profit because marketing people are developing new tools and new methods for their successful marketing communication. Marketing has been offered some huge new horizons thanks to the internet. Along with the tools of the conventional commercial communication it keeps at disposal even the interpersonal communication. Personal user data-gathering helps with addressing the customers directly. One of such tools to help the companies with direct input of the customers' needs, desires and demands of an exact brand are the social networks. Such premise is...

The Oppidum of České Lhotice and its hinterland
Danielisová, Alžběta ; Venclová, Natalie (advisor) ; Macháček, Jiří (referee) ; Čižmár, Miloš (referee)
The aim of the work is to attempt a new approach towards ones of the phenomena of the prehistoric archaeology: the late La Tne forified agglomerations - the oppida. Their economical potential was formerly tested only on the industrial or commerce base but not from the ecological point of view. Their agricultural potential has been challenged in many publications both for specific locations, that were not directly in the primary agricultural settlement zone (the fertile lowlands), and for the material collection which usually lacks the tools used for ploughing. However, the urban structure of the sites reveals the evidence of the traditional agricultural household units and together with the evidence of breeding the livestock the subsistence requirements should presuppose at least minimal human factor dedicated to agricultural work. Also the potential of the landscape possibly allows for cultivating of crops in the vicinity of sites. This work is aimed to analyze the agricultural potential of the oppida and by archaeological modelling to test both the hypotheses concerning the oppida subsistence strategies: if they were independent producers of their own foodstuff or if they were dependent on the supplying from their sites in their subordinate hinterland. The main object for this analysis is one particular...

Financial analysis of Telefónica O2 Czech Republic
Šaněk, Petr ; Kopkáně, Heřman (advisor) ; Matuštík, Ondřej (referee)
This work is analyzing the financial situation of Telefónica O2 Czech Republic, a.s. It is analyzed by most used indicator like profitability, solvency and liquidity ratios. It also uses investment valuation ratios and economic value added. The analysis is also comparing the company with its main competitors on the field of mobile communication. The assets and net profit of the company are heavily influenced by the state correction in 2003. From indicators not influenced by the correction we can tell, that financial situation was good in spite of negative net profit. The financial situation in years 2003 to 2008 is very good. Profitability ratios of the main competitor T-Mobile Czech Republic, a.s. are very similar but the researched company has been a little bit better most years. On the basis of this financial analysis I find the financial health of the company very good, with great potential.

Help Intervention Center Vysočina Region - Socio-legal Aspects of Social Service Provision
SVOBODOVÁ, Vendula
The main objective of the thesis was to map possibilities of a co-operation among the intervention centre and other entities interested in helping to people threatened by the domestic violence. The current status was taken from the professional literature. There is described an issue of the domestic violence, types and forms of the domestic violence, its characteristics and dynamics, causes, consequences, legal framework of the domestic violence, its actors, entities helping to people threatened by the domestic violence and an interdisciplinary co-operation. The qualitative research was used in the thesis. A tool for the data collection was a semi-standardized interview. Questions were based on theme ranges concerning the examined issue. The research sample consisted of 13 workers of the entities helping to people at risk of the domestic violence in the Highland (Vysočina) region. The research showed that the domestic violence is a very wide-spread and still underestimated issue. At the same time it is seen a considerable progress in the area of the help to people at risk by the domestic violence. Further the research showed that workers do not exactly know services provided by the Intervention Centre of the Highland (Vysočina) region. Thanks to this fact there can occur a disinformation of people threatened by the domestic violence. The staff can determine the most often demanded help from the side of the potential service users. They can also recognize that not always it is about the help the intervention centre is able to provide. The research does not confirm that the personnel generally would be influenced by prejudices at their work with people at risk by the domestic violence. But they were certainly also in their professional life influenced by a personal experience with the domestic violence that acquired in their neighbourhood. The research raised a possibility of a co-operation among the intervention centre and other entities, namely organizing case conferences. This thesis can be used in practice for an acquisition or addition of professional experience related to the issue of the domestic violence and available provided services.

Computational methods in single molecule localization microscopy
Ovesný, Martin ; Hagen, Guy Michael (advisor) ; Plášek, Jaromír (referee) ; Fliegel, Karel (referee)
Computational methods in single molecule localization microscopy Abstract Fluorescence microscopy is one of the chief tools used in biomedical research as it is a non invasive, non destructive, and highly specific imaging method. Unfortunately, an optical microscope is a diffraction limited system. Maximum achievable spatial resolution is approximately 250 nm laterally and 500 nm axially. Since most of the structures in cells researchers are interested in are smaller than that, increasing resolution is of prime importance. In recent years, several methods for imaging beyond the diffraction barrier have been developed. One of them is single molecule localization microscopy, a powerful method reported to resolve details as small as 5 nm. This approach to fluorescence microscopy is very computationally intensive. Developing methods to analyze single molecule data and to obtain super-resolution images are the topics of this thesis. In localization microscopy, a super-resolution image is reconstructed from a long sequence of conventional images of sparsely distributed single photoswitchable molecules that need to be sys- tematically localized with sub-diffraction precision. We designed, implemented, and experimentally verified a set of methods for automated processing, analysis and visualization of data acquired...

Ancient astrology: signs of zodiac
Látalová, Petra ; Musil, Jiří (advisor) ; Stančo, Ladislav (referee)
V dnešní době, kdy se řada lidí odvrací od exaktních věd a hledá určitou alternativu k čistě racionálnímu obrazu světa, se zvyšuje zájem o esoteriku, parapsychologii, alternativní medicínu a také astrologii. Astrologie Je obor, který se zabývá vztahy mez1 postaveními Slunce, Měsíce, planet a hvězd a děním na Zemi. Ačkoli řada odpůrců jí upírá označení vědní disciplíny, je astrologie podobně jako věda založena na empirii, pozorování a statistických metodách, ve kterých rovněž využívá poznatků astronomie. Při svých interpretacích vychází z názoru, že vesmír tvoří jeden celek a tedy všechny jeho součásti nutně musí souviset s ostatními. Právě díky mému hlubšímu zájmu o astrologii jsem se rozhodla zjistit více o tom, odkud vlastně astrologie vzešla, jak se dále šířila a rozvíjela, zdali už v antickém světě dosáhla takové úrovně a poznatků, jakými disponuje dnes a také v jakém prostředí a kým byla praktikována. Výše zmíněné otázky se pokusím zodpovědět v jednotlivých kapitolách. Celá práce bude rozdělena na dvě části, přičemž v první nastíním vývoj astrologické disciplíny a její šíření v antickém světě, ve druhé se budu věnovat jednotlivým znamením zvěrokruhu a jejich zobrazením. Také se dotknu některých astronomických otázek, neboť právě astronomie s astrologií úzce souvisí a její rozvoj byl velmi důležitý pro...
