Problems in Theories of Low Stress Creep Mechanisms
Kloc, Luboš ; Sklenička, Václav ; Fiala, J.
Viscous creep behaviour of many materials including creep resistant steels was observed at temperatures close to one half of absolute melting point and at very low stresses. The experimental results were interpreted as Coble diffusional creep and/or Harper-Dorn dislocation creep. Some of the results are in a very good agreement with the Coble theory of diffusional creep and support an idea that the diffusional creep is an important deformation mechanism under certain loading conditions. Nevertheless, another results are not fully compatible with the theoretical predictions. Some authors dispute the role or even the very existence of the diffusional creep and offer the Harper-Dorn creep mechanisms instead. In fact, there are many theories trying to deescribe Harper-Dorn creep mechanism, but none of them is capable to explain all observed properties. Transition (or primary) stage observed at low stress creep regime exhibits also some properties which contradict all existing theories. The observed effects which cannot be explained by the current theories are: i) a large scatter of creep rates observed for coarse grain materials, ii) creep rates much higher than those predicted by the diffusional creep theory while the creep rate dependence on grain size is maintained, iii) transition stage duration is independent of stress, iv) transition strain is dependent on temperature. Despite the problems in theoretical description, the experiments show that the viscous creep regime in structural materials must be considered as an important behaviour of the structural materials.

Is import of goods from european countries to Czech republic more or less influenced by changes in nominal and real exchange rates than in non european countries?
Vereš, Jan ; Stroukal, Dominik (advisor) ; Slaný, Martin (referee)
This bachelor thesis analyses the connection between import of goods from foreign countries to Czech Republic and the exchange rate changes. The initial hypothesis of this paper is to prove that the depreciation of domestic currency has positive influence on balance of trade balance. For this purpose there is eight econometric models which were created by using time series from years 2003 to 2016. These models are divided in pairs among four chosen countries. For each country two models were created that follow the development of trade balance between Czech Republic and one of the countries in two different time frames. All the models always use the real effective exchange rate, growth rate of GDP for Czech Republic and growth rate of GDP for one of the countries as explanatory variable. It is connected with the second task of this thesis, which is the analysis of the differences in the behaviour of the models that belong to the countries which are members of the EU and these that are not. The aim is to find out whether the existence of tariffs on imported goods from countries out of the EU causes visible differences in the behaviour of the variables that were included in the models. Based on the outcomes of all eight models the main hypothesis has been proved right for three out of four countries. In the models for Germany, China and France the relation of real exchange rate and trade balance came out as positive in long term, in short term the outcome was ambiguous. The second question of this thesis has been answered, but its added value is questionable. The final models for each state do show some noticeable differences and they can be used to determine if the influence of the change of exchange rates on trade balance is smaller or bigger in the countries where tariffs are used. On the other hand, from the results we can learn that the sample of only four countries is insufficient for the deduction of any conclusions.

Do women with children have lower wage rate than childless women?
Lukášová, Nikola ; Brožová, Dagmar (advisor) ; Čermáková, Klára (referee)
The aim of the thesis is to demonstrate if women with children in the Czech Republic have a lower wage rate than childless women. The data from WageIndicator Foundation was processed by using the the least squares method. The conclusion is that motherhood has a negative impact on salaries. I also found that the depreciation of human capital influences only women with two or more children. It can be caused by the lenght of maternity leave. The main finding is that the wage penalty for motherhood actually exists. And the society and politicians should give the motherhood penalty more attention in the future.

Orienteering club support system
Buk, Jindřich ; Vojíř, Stanislav (advisor) ; Sklenák, Vilém (referee)
Nowadays, an increasing number of processes and life situations is getting IT support. Often the use of the Internet aims to accelerate and simplify existing processes. In addition, there is a big area of social networking that can be complementary. This thesis deals with the possibilities of using web technologies to support the running of a club and its subsequent development. Indeed, the club has the potential to simplify and automate many processes which previously have been carried out by someone in person. It has also a potential to use social networks for its publicity and development. The aim is to first determine what areas of the clubs operations are the most appropriate to be supported by any information system. Another objective is to find out how other clubs already integrate any information systems. The final objective is to design and create a specific application. The first two objectives are addressed through a survey among the leaders of the biggest Czech clubs. Indeed in these clubs, the use of automation and simplification of existing processes could have a great potential. The proposal for a specific application is then based on the previous survey and the field experience of the author. While serving many existing processes in running the club, the proposed application adds many elements of social networking.

Social housing - comparison of Concept of Social Housing in the Czech Republic 2015-2025 and Austrian social model
Hejduk, Radim ; Krebs, Vojtěch (advisor) ; Barák, Vladimír (referee)
The thesis is focused on social housing - public policy, that is applied in many countries of the EU. Czech Republic is currently trying its implementation. Due to rising household's costs of housing, rising expenses on demand-oriented housing policy in form of housing benefits and difficult to solve social exclusion, social housing appears to be one of the more accessible ways of solution. The goal of the thesis is at first to analyze and evaluate known forms of social housing and its application from the economic perspective, then to form reccomendations for the Conception of Social Housing for the Czech Republic in the period 2015-2025 using comparison to already-existing Austrian model. This text answers the main research question how does functioning model of social housing look like and what are the economic impacts of it on households.

Chytrá a udržitelná města v kontextu vědecké a inovační strategie EU
Horniecká, Marie ; Žamberský, Pavel (advisor) ; Procházková Ilinitchi, Cristina (referee)
The thesis explores how the EU support to research and innovation towards urban sustainability is designed, what the existing EU intiatives striving for achieving smart and sustainable cities are. The analysis of theoretical approaches forms the basis for developing the definition of smart and sustainable city for the purpose of this thesis. An overview of the principal EU strategic documents which address urban sustainability together with European networks is provided in order to demonstrate the linkage to the research Framework Programmes. A separate chapter is devoted to the analysis of the most pressing challenges European cities face nowadays. Database of EU funded research and innovation calls and projects is examined (E-CORDA). Calls and projects related to urban areas are identified and juxtaposed with the urban problems. Final recommendations concern with social aspects of sustainability which should be, in the author's opinion, addressed in future EU research Framework Programmes with a particular attention.

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.

Řízení IS/ICT se zaměřením na sourcing služeb informačního systému
Šebesta, Michal ; Voříšek, Jiří (advisor) ; Havlíček, Zdeněk (referee) ; Příklenk, Oldřich (referee) ; Král, Jaroslav (referee)
Research on outsourcing has been around for several decades, while recent evolution in the information systems discipline towards ICT service commoditization significantly changes the context of decision-making. Services that are available on-demand via the Internet allow organizations implementing functions they demand in a fraction of time. This trend represents a chance for organizations seeking to use advanced ICT services without a need of major investments. Problem is the current lack of guidelines and tools for managing ICT services and their outsourcing. Given the trends on the ICT service market, it is expected that much of the IT management in the future will encompass the ICT services and utilize service-level structures. Methods currently available are either too broad or encompass only small part of the whole problem. Ad-hoc or unsound decisions in this area might cause major complications in terms of quality, usability, integration, and consequently influence total cost of organizational IT. Organizations need to either revise existing models or propose and implement completely new models to manage their IS/ICT. This thesis deals with the management of IS/ICT with focus on the ICT services outsourcing. It discusses available sourcing models in the literature and links them to the various interconnected areas. Based on these areas, it presents an integrated view on IT outsourcing strategies. Most importantly the thesis proposes an original concept for decision-making about outsourcing of ICT services named the SOURCER framework. This approach utilizes the presented outsourcing strategies, and introduces a complex methodology and decision-making criteria that will assist organizations with selection of ICT services in order to maintain and manage a most suitable ICT service portfolio. The decision-making is based on four essential viewpoints: function, costs, time, and quality. These viewpoints are discussed, individually analyzed, and serve as a basis for further research. The whole framework is developed and validated according to Design Science Research Methodology (DSRM). Individual components are evaluated using a survey among a group of selected IT managers. Proof of concept is then established by a case study on framework use in a real organization. This case study covers strategy specification, business--IT alignment, specifying service architecture and its interconnections, outsourcing, and management of the ICT service portfolio.
