Logging from an application written in the Java programming language
Hanzel, Matej ; Pavlíčková, Jarmila (advisor) ; Černý, Michael (referee)
This bachelor's thesis explores problems of logging from an application written in the Java programming language. The introduction expressed the idea of the necessity of obtaining relevant data directly from an entity which represents the originator of a problematic situation solved later through various thinking operations. The thesis describes not only the inclusion of the concept of term logging in the general context of term process, but is particularly devoted to the logging architecture in object-oriented programming languages. The greatest attention is paid to the description of logging facades Simple Logging Facade for Java and Apache Commons Logging, and the logging libraries Java Util Logging, Log4J and LOGBack, further complemented by the practical implementation of their use in Java applications. The author of this thesis holds the view that it is not possible to express a clear and generalized opinion on using one specific logging library exclusively despite the absence of significant differences between them. It is important to carefully consider the requirements demanded and select the most appropriate solution that best suits each situation.

The methodology of the removal of layers of corrosion products from the surface of the metal objects by using low-pressure plasma
Krčma, František ; Řádková, Lucie ; Grossmannová, Hana ; Miková, Petra ; Černý, Martin
Metodika řeší aplikaci nízkotlakého plazmatu pro šetrnější odstraňování vrstev korozních produktů z kovových archeologických nálezů. Jedná se o tzv. „suchou metodu“, to znamená, že samotný předmět není ovlivněn vodou ani rozpouštědly. Aplikace vede k částečné až úplné desalinaci povrchu předmětu
a zejména výrazné snížení koncentrace chloridů. Výhodou je aplikovatelnost současně na větší počty předmětů. Aplikací postupu lze dosáhnout i výrazného zrychlení procesu odstraňování korozních vrstev za aplikace nižší síly. Metodu je možné použít i na ošetření předmětů zhotovených z mědi a jejích slitin, kdy je třeba zachovat
i vrstvu ušlechtilé patiny. V tomto případě je ale nezbytné pečlivé zvážení aplikace zkušeným konzervátorem, protože je obtížné jasně odlišit neušlechtilou a ušlechtilou patinovou vrstvu.

Henrik Ibsen: An Enemy of the People - Complex Scenic Design
Dvořák, Pavel ; ČERNÝ, Martin (advisor) ; GLOGR, Karel (referee)
Theoretical part of this work is concerned about historical roots of the theatre play Enemy of the People by Henrik Ibsen. It is also concerned about history of Estate Theater in Pra-gue, where the play should take place. I am also concerned about the background of the author Henrik Ibsen's life. And also part of the work is about other previews authors, that have been working on the play before. In Practical part I offer new solution for visual part of the drama in context of present time and space.

Identity management in the bank
Gustab, Tomáš ; Svatá, Vlasta (advisor) ; Černý, Miroslav (referee)
The main focus of this thesis is to analyse the identity management of Czech bank. The author deals with the authentication and authorization of bank employees, the lifecycle of identities and also suggests the operational improvement of systems that relate to identity management. The aim is to show the view from every angle on identity management, highlight the problems and propose countermeasures, respectively measures to improve the identity management running.The main methods of research are analysis of documents, unstructured interview with employees and observation of systems operation. The benefit of this work is in providing author's opinion and recommendations, which can lead to an overall better running identity management in the bank.

Algorithms for various geometric problems over zonotopes and their applications in optimization and data analysis
Rada, Miroslav ; Černý, Michal (advisor) ; Vlach, Milan (referee) ; Kopa, Miloš (referee)
The thesis unifies the most important author's results in the field of algorithms concerning zonotopes and their applications in optimization and statistics. The computational-geometric results consist of a new compact output-sensitive algorithm for enumerating vertices of a zonotope, which outperforms the rival algorithm with the same complexity-theoretic properties both theoretically and empirically, and a polynomial algorithm for arbitrarily precise approximation of a zonotope with the Löwner-John ellipsoid. In the application area, the thesis presents a result, which connects linear regression model with interval outputs with the zonotope matters. The usage of presented geometric algorithms for solving a nonconvex optimisation problem is also discussed.

Odhad zajišťovacího poměru (Hedge Ratio) v řízení zásob
Máková, Barbora ; Černý, Michal (advisor) ; Cahlík, Tomáš (referee)
Companies dependent on commodities for their production have to deal with volatile commodity prices and should employ measures for risk reduction as unfavourable spot price development may cause significant losses. A useful tool for diminishing the risk is hedging on futures market; however, this approach faces a crucial question of optimal hedge ratio determination (ratio between spot and futures units). Our thesis examines nine different ways of optimal hedge ratio estimation (naive, Sharpe, mean extended Gini coefficient, generalized semivariance, value at risk, and minimum variance through OLS, error correction, GARCH, and bivariate GARCH models) and evaluates their efficiency using the data on eight different commodities. The results differ across the respective commodities and cannot be generalized. Two conclusions resulting from the analysis refer to performance of naive and OLS hedge ratios and constant vs time varying hedge ratios. We find that complex hedge ratios, such as bivariate GARCH or VaR hedge ratios, do not outperform naive and OLS hedge ratios and that the results of constant hedge ratios are mostly as good as results of time-varying hedge ratios.

Web application containing the information about exchange rates on the Slovak and Czech market
Stríž, Oliver ; Pavlíčková, Jarmila (advisor) ; Černý, Michael (referee)
The aim of this bachelor thesis is to make the market analysis and to test my theorem. I work with hypothesis that people who are visiting web portals containing the information about exchange rates can use the application for finding exchange rates from multiple banks in different countries simultaneously. The users consider this application very useful and also very beneficial because of the tool what shows them which bank is more favorable to change the money - either in the home country or in the foreign one. In the thesis, the reader will find information about a draft of application for catching the exchange rates and also about its programming. There is also draft of database generated by framework Hibernate in the thesis. In the thesis is described my way of thinking during creating the PHP scripts.

Analysis of Czech Constroction Industry from 2004 to 2013 with Regard to Phases of Bussines Cycle
Černý, Martin ; Chmelová, Pavla (advisor) ; Sunega, Petr (referee)
Presented thesis brings forward a complex insight on Czech construction industry in years 2004-2013 with regard to the economic crisis in years 2009 - 2013. The theoretical part of the thesis present us with certain varieties of construction techniques, the importance of construction industry for Czech economy and selected parts of economic crisis theory. The introduction to the applicative part of the thesis is drawn as a contrast in various performance indicators in construction industry in between an era of Czech construction development (2004 - 2008) and an era of decline of construction industry (2009 - 2013). Author of the thesis, using the international comparative method, comes to the conclusion, that the Czech construction industry was affected by the economic crisis the most, among other factors also thanks to the public sector failure in times of crisis. The conclusive part of the thesis talks about the future of the sector, author predicts that thanks to the public investment and overall economic resurgence, future of the sector is quite bright but also points out that the long term deficiencies in public sector are still present.
