Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.

Spain as a tourist destination
Zbořilová, Kristýna ; Abrhám, Josef (advisor) ; Havlíčková, Blanka (referee)
This Bachelor's Thesis deals with tourism in Spain. The topic is quite broad so the main aim of the thesis is to evaluate tourism in two significantly different regions - Andalusia and Basque Country. The first chapter defines terms related to tourism that are essential to coherently understand this thesis. For example, this part defines the term tourism and its typology. The second chapter focuses on tourism in all of Spain. In particular, Spain is described in terms of history and how tourism is evaluated. In addition, Spain's most attractive places are presented. The second to last, and final chapter are similar in structure in order to perform a comparison of the chapters. The first part of both chapters describes the regions. Then, tourism is evaluated by using statistics from incoming tourists. Finally, SWOT analysis is used to comprehensively evaluate the previously mentioned information.

Podnikatelský plán vybrané firmy (model lean canvas)
Strupplová, Lucie ; Filipová, Alena (advisor) ; Zeman, Jiří (referee)
The well arranged and instructivee business plan is the basic part of every business project.. Currently is very often used the lean canvas model of the business plan. This model shows us very istructively all the factors influencing the project realisation. The dissertation is divided into the two basic parts. In the thoretical were compared the essential forms of the business plan with their differences. The practical part consists of creating the lean canvas model for the progressive company using the UAV and the MAIA application, monitoring the flight of the UAV. The economic data were analyzed and the structured scheme of the project, with the prediction was realized. The lean canvas model was very useful and optimal for this company and it´s project.

Výběr a implementace open source nástroje pro řízení portfolia projektů
Marek, Jan ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
Methods and ways of implementation of changes and innovations in companies through project management are in today's society very well established. There exists methodologies, techniques and tools for the management of individual projects. However in a role of project manager, I very often faced the fact that companies are performing the project portfolio management in very intuitive way. This in itself leads to failed and prematurely terminated projects, initiation of the wrong projects or realisation of correct projects, but at the wrong time. Very often I have also recognized, that there is lack of awareness of fact, that there are also Open Source applications that can help with the organization's portfolio. This thesis deals with the definition of requirements, search and selection of proper OSS application and subsequent implementation. In the first part of this thesis I prepare a theoretical framework about PPM, and on that basis then identify and verify a set of requirements for selection of right OSS PPM application. The next section of thesis describes searching for suitable applications from a variety of sources, assessment against the requirements and the final selection. In the last part the implementation project is drafted, which aims to serve other colleagues in project management as one of the possible implementation paths. The outputs are then continuously confronted with experts in matter of projects and project management in the field of IT in order to maximize symbiosis between theory and real life experiences. Virtually every project management methodology defines the collection of already-proven techniques, best practices or lessons learned from the previous similar implementations. The main contribution of this thesis I see in fact that it contains not only the design of the project implementation, but also describes a logical path, what leads to the result. Therefore this thesis could be used as a base or discussed best practice, when a project of implementation of PPM application in place.

Access to Information and Access to Justice in Environmental Matters in the Republic of Irealand and the Czech Republic
Vítková, Martina ; Stejskal, Vojtěch (advisor) ; Sobotka, Michal (referee)
This diploma thesis deals with access to environmental information and access to justice in environmental matters introduced by Aarhus Convention in the specific conditions of Czech Republic and Ireland. These rights are considered to be very important tools for environmental protection. At a time when people threaten their own existence by negative interference with the environment it is necessary that effective means for its protection exist. These means are access to environmental information and access to justice in environmental matters, which together can be called as environmental procedural rights. The first chapter of this thesis presents the sources of environmental procedural law and observes the development of law at international, European and national level. The most important international document in this field is the Aarhus Convention that was adopted in 1998 by most of the European countries and that provides for access to environmental information, access to justice and public participation in environmental decision-making. This convention has largely affected the law of the European Union, where several directives has been adopted, including most importantly the Directive 2003/4/EC on access to environmental information and the Directive 2003/35/EC on public participation in...

Introduction to bio art
Šperanda, Nina ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
Bio art is a contemporary art practice that works with living organisms (except humans) or is created in cooperation with living organisms. It is relatively new art movement that is rooted deeply inside the history of evolution, domestication of animals and plants, technological discoveries, their development and science. Never before was art questioning its ethics and aesthetics in such profound, molecular and sub-molecular way.
In this work I will consider the historical influences and conditions that led to current developments in the field. I will also try to explain the problematics of defining what bio art is and try to clarify the associated terminology. Most relevant and ground breaking works in the field will be mentioned as some new recent developments.
Aesthetics of bio art is also an important subject often set aside by the ado around ethics of it. It is an extremely important subject to be considered when talking about bio art and I will try to sketch out a brief outline of it with references to philosophy and contemporary bio art theory.

Vegetation succession and soil development on heaps from brown coal mining
Veselý, Martin ; Chuman, Tomáš (advisor) ; Šefrna, Luděk (referee)
Plant diversity and selected soil parameters from 36 sites placed on brown coal mining spoil heaps were analyzed and compared. Spontaneously revegetated or technically reclaimed spoil heaps of different age were situated in brown coal mining district of eastern Most basin in north western part of the Czech republic. Samples were sorted in groups according to vegetation growth and type. Plant diversity increases during succession development and is higher on non-reclaimed sites than reclaimed sites, where diversity decreases with time. Soil bulk density decreases during succession on all sites. Soil pH is decreasing too and this process is faster on spontaneously revegetated sites. Old successional forest type sites have very acid soils probably due to properties of original mineral matrix. Thickness of organic horizon and A horizon is increasing during succession and they appear in mid-aged sites first. Content of soil organic carbon is increasing continuously. Non-reclaimed sites reach higher contents, mainly because of higher content of fossil organic matter in spoil mineral matrix. Keywords: vegetation succession, soil development, reclamation, brown coal mining heaps

Political Economy of European Security: A Role of Industrialists in forming the ESDP
Vacík, Lukáš ; Střítecký, Vít (advisor) ; Bureš, Oldřich (referee)
The thesis aims to determine the scope and extent of the European defence industrial sector influence on the process of European defence formation, or more precisely in the field of defence and security cooperation (ESDP/CSDP). The question of the European defence sector's role in shaping the defence and security cooperation in Europe has not been properly explored, thereby it provides an ideal topic of choice for my thesis, The thesis is divided into three main parts: the introduction, the analysis consisting of five sections and finally the conclusion. The thesis analyzes an industrial sector itself, while exploring the process of creation of internal market within the framework of the Roundtable of European Industrialist initiative. It then moves on to discuss the European military industrial complex and it argues for the need to introduce a new term "European Defence Industrialists" in order to improve our understanding of defence cooperation in the EU. As for the thesis theoretical approach, a classical IR theoretical approach in general and classical theoretical take on European integration have proved insufficient. Therefore, the thesis explores the specific environment of European industrial sector with the aid of the liberal economics approaches. In so doing, it establishes that liberal...

Influence of meadow management on the migration behavior of selected species of butterflies
Bubová, Terezie ; Langrová, Iva (advisor) ; Farkač, Jan (referee)
Migrations are the key process and one of the basic biological features, which allow survival of endangered species in fragmented landscape. In the last decades, agriculture intensification, industry and urbanization caused that number of natural butterfly habitats has significantly decreased. The localities originally suitable for butterflies are currnetly converted to farmland or building plots. This PhD thesis aimed to find a compromise solution of meadow management, which should allow a commercial use and concurrently do not jeopardize the continued existence of endangered or threatened species. The main idea of this study was in the intentional emigration causing in the middle of flight period, which should lead into resettlement of the population to another (potentially more suitable) locality. Possibility of aimed manipulation with butterfly emigrations would be considered as a major breakthrough in their protection.
The investigated species Phengaris nausithous (Bergsträsser, 1779) and Phengaris teleius (Bergsträsser, 1779) are both considered to be flagship species for protection of European butterflies at open meadows. This study is based on research, which was carried out in 2013-2015 at 17 patch in localities Dolní Labe, Czech Republic. In above mentioned years, one selected meadow was mowed in the middle of flight season and the emigrations were then monitored using mark-release-recapture method. Results of population and migration characteristics were calculated in MARK 8.1 software. Subsequently, the effect of mowing on emigration (comparison of emigrations from the meadow before and after mowing) was evaluated using Statistica 13.
The hypotheses of this study were based on the assumption, that the loss of resources after well-timed mowing should increase the activity of adult butterflies. During the monitoring, number of emigrations was increased only in flight season 2015. Unfortunately, the statistical evaluation did not show significant effect of mowing on migrations. On the other hand, the hypothesis dealing with colonization of nearest meadows was confirmed.
Effect of intentional emigration caused by management interventions was unfortunately not proved. However, we found out, that even though the population at one mowed meadow decreased clearly, the metapopulation size at the locality remained more or less stable.
At investigated (mowed) meadow, there was observed a sharp decline of P. nausithous abundance. On the other hand, P. teleius population was only slightly reduced. It is therefore conceivable, that P. teleius are not as susceptible to innapropriate term of mowing. The results obtained in our research conclusively displayed no possible positive effect of mowing in the middle of flight season and a necessity of suitable management maintenance at localities inhabited by Phengaris butterflies.
