Covering the Working Space of Mobile Robot
Krejsa, Jiří ; Věchet, Stanislav
Equally distributed covering of working space is essential in some mobile robot applications, such as presentation robotics or security robot patrol. This paper explores a method for such covering based on rapidly exploring random trees (RRT) algorithm. RRTs can cover the working space close to completeness while uncovered areas are quickly reduced. The algorithm can be modified to emphasize certain areas of interest by appropriately generating corresponding goals. Method performance is compared to random walk in simulation experiments.

Time management
Hanus, Filip ; Franková, Emilie (advisor) ; Motlová, Veronika (referee)
It is of great necessity to know how to manage time. The theoretical part of this thesis is concerned with the definition of time management, its origin and evolution. It covers the basic rules of efficient time management and the principles of efficient work organization. It describes the usage of goals and their setting, circadian rhythms and their influence on our productivity and the most common factors that steal our time. Based on the analysis of time frames and half-structured interviews, the empirical part follows the lives of six university students for two weeks. Our goal is to find out how the respondents use their time, what is their knowledge of time management and also to cover the difference between students living in a room alone and students sharing a room with one or multiple roommates.

The migration crisis in Europe and subsequent implications for Swedish welfare state
Lacková, Dominika ; Bič, Josef (advisor) ; Němcová, Ingeborg (referee)
In general, migration is one of the most important global challenges. The topic of regulating migration flows came to the fore in relation to the current Europe's migration, or more precisely, refugee crisis. It has been described as the most massive migrant's crisis since the WW2. Unprecedented influx of immigrants and refugees in 2015 resulted in that even the best prepared European countries, such as Sweden, have reached a tipping point with regard to respect EU standards related to reception and processing of asylum applications. Master thesis covered two main analyses - the relevance of the refugee crisis in the EU in regards to the Swedish welfare state and the subsequent implications arising from the refugee crisis for the Swedish welfare state.

Potential of IoT in Smart City
Pavlíček, Tomáš ; Gála, Libor (advisor) ; Basl, Josef (referee)
The aim of this masters thesis is to identify, in which phase of adoption of Internet of Things (IoT) application areas of concept Smart City are nowadays Czech regional cities, what is their outlook to 2025 and also identify in which dimensions of concept Smart city, supported by IoT technologies, perceive Czech regional cities the greatest potential. Based on information obtained from the studied materials, the concept of Internet of Things (IoT) is described, along with a detailed description of one of its application area, namely Smart City. This area is further divided into specific dimensions, that cover specific application areas which can, through internet technology, support things in a special way. With these insights, the questionnaire (built on identified IoT application areas of smart city) was developed. Thesis should be beneficial for all towns in the Czech Republic, because it provides a comprehensive view of individual IoT application areas of concept Smart City including information on which of these IoT application areas are currently focusing regional cities, and on which they want to focus to the future. On the other hand, the survey results could also be beneficial for commercial entities, which focus on IoT implementation in cities. These entities will be able to recognise which IoT products are currently best for cities.

Analysis and design of intranet structure
Novák, Miroslav ; Pour, Jan (advisor) ; Šedivá, Zuzana (referee)
Nowadays, Intranet is an inseparable part of every company, notwithstanding of their size or field of activity. Both, in my work and personal life, I often come across different intranets that usually do not get a positive response. But they usually have the same source of the problem, which is based on their wrong structure. This is why is chose this topic for my thesis. The goal of my thesis is to perform an analysis of an existing intranet of a particular company and subsequently create a design of the intranet new structure using the card-sorting method. This thesis primarily represents a generalized method of how to proceed during such realization and which areas to look into. Theoretical part of this thesis covers the topics of information architecture and also the term intranet itself, where the most frequent issues I came across in the intranets are pointed out. Practical part covers the analysis itself, where I focus on the structure of the existing intranet, categorization of its content, connections with other systems, customization, permission management, surveys of contentment, and intranet usage. The analysis is performed manually by scanning through the existing intranet of the company, since other methods or approaches could not be applied due to technical limitations or insufficient permis-sions. Based on the outputs of the analysis, web categorizations and the card-sorting method, a design of a structure of the new intranet has been proposed. The design itself is a demonstration of the method how to approach the new intranet design.

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.

Opportunities for Young People up to 30 Years Old in the Labor Market in the District of Písek
KABÁTOVÁ, Zuzana
The Bachelor´s thesis called "Opportunities of young people up to the age of 30 on the labour market in Písek district" deals with the unemployment issue of young people target group, problems with their placement on the labour market and the structure of vacancies in comparison with qualification criteria in a set group in Písek district. Fresh graduates applying for their first job are considerably disadvantaged in competition with other applicants. They lack of job experience as well as basic working habits; what is more, they fail in being acknowledged with the labour market and employers´ requirements on their future employees. Their unreal visions often contribute to their unemployment, too. Theoretical part clarifies the phenomenon of unemployment and various types of unemployment from frictional, cyclical, seasonal to structural unemployment are confronted. The other theoretical part deals with labour market in general, supply and demand of workforce, job offers and study programmes offers so that there is an equilibrium of the number of graduates at various specialisations and demands of labour market. More attention is paid to the importance of work for a young person, which is the precondition for one´s independence and taking over the responsibility for work done. The problem of young people and unemployment has become so serious that European Union decided to deal with it. One proposal of European Parliament suggests that the state ought to guarantee young people the security for work, offers of requalification courses or work internships. These measures ought to contribute to the prevention of unemployment within this target group. One of the goals covers the field of employment and considers decreasing the unemployment rate of juvenile and young people between the ages of 15 and 24 by a third (compared with the year 2010). The aim of the practical part of the thesis was to find out what visions of young people concerning to their involvement in labour market are like, if they correspond with their conditions and capabilities, whether they look for jobs entirely in their field of study or they are interested in requalification if needed. Questionnaire survey was used for confirmation the hypothesis. The practical part states the results of field research which was carried out in the form of anonymous questionnaire. The questionnaire survey inquired about education of the target group of young people up to the age of 30, their knowledge and skills in the fields of foreign languages, computer literacy and driving vehicles. The survey inquired about the graduates´ willingness to work in shifts, in jobs involving business trips, in various working environments as well as their willingness to work aside their qualification fields. Their near-future visions were verified, i.e. the interest in early job placement, their own activity in looking for a job, the effort to enlarge their qualifications. The final part includes some recommendations aimed at prevention of unemployment particularly focused on acquiring practical skills and habits.
