Architectural database refactoring
Nguyen Trung, Hoa ; Palovská, Helena (advisor) ; Krch, David (referee)
This bachelor thesis deals with database architectural refactorings. Its purpose is to describe each and every architectural refactoring method in detail on theoretical level with following author's own examples. These examples contain schema update mechanics and an outline of application code update. First of all, there will be an explanation of what refactoring stands for and what are the main differences between database refactoring and code refactoring. Following is detailed description of each and every architectural refactoring method with its principle, benefits and potential tradeoffs. The next part consists of author's own examples where update mechanics from theory are applied. Final chapter evaluates achievement of objectives, contribution of thesis and proposals on how can this thesis be extended.

Creation of the Enterprise Architecture model according to the TOGAF framework
Čapek, Jan ; Doucek, Petr (advisor) ; Zeman, Petr (referee)
The present diploma thesis aims at introducing the Enterprise Architecture and creating an abstract model of a company. The primary focus is on application and process layers as defined in the architecture framework TOGAF. The thesis is divided into theoretical and practical part. The theoretical chapter starts with a business model analysis which means to describe mission vision and companys values as a part of the strategy framework. Furthermore the business processes are described in the latter part of this section. This chapter attempts to explain how to map a business process and to categorize it by nature and maturity level. Penultimate chapter introduces the Enterprise Architecture in general. This section includes arguments as to why the companies should be concerned with the Enterprise Architecture advantages of the Enterprise Architecture implementation into the companys documentation relationship of companys core business and IT and examples of the Enterprise Architecture frameworks. The last chapter deals with the TOGAF framework where Architecture Development Method is described. This means how Enterprise Architecture model is created and how to implement changes into the layers according to the TOGAF framework. Simultaneously the last section of this chapter describes the reference models which provide graphical overview of all abstractions layers. The practical part of the thesis elaborates on the theoretical part using the Architecture Development Method process in order to create the Enterprise Architecture model according to TOGAF framework. Same as the theoretical part it only focuses on the application and process layer. Firstly the business model is decomposed into vision mission and companys values to the companys strategy and business goals in order to grasp further understanding of business processes detailed description. Subsequently the abovementioned aspects are recomposed to create process map which provides the management overview. The application layer undergoes the same process; nonetheless the process map is replaced by information system description and reference model creation. Once the models are created the thesis compares them with the business and strategic goals. The benefit brought by this thesis is critical evaluation of current status to propose changes to achieve target architacture according business and strategic goals established by management.

Marketing strategy of the company 3M in social media
Němec, Tomáš ; Halík, Jaroslav (advisor) ; Luňáčková, Michaela (referee)
Diploma thesis focus on social media as a phenomenon of modern times and their use in a marketing. I will introduce four most frequently used social media - Facebook, Instagram, Twitter and YouTube as well as an outline the possibility of their use in marketing. Marketing strategy in social media I decided to introduce through a concrete example - an international company 3M. This company I chose mainly because it operates in the market of industrial products, where online marketing is not as much used and also because it cooperates with University of Economics. After introducing the basic marketing theories and explanations of basic terms I will analyze an existing 3M marketing strategy in social media and on the basis of the analysis and obtained data I will suggest my own possible marketing strategy for the company 3M, which connects all the aforementioned social media.

Demonstrate the principles of application development for Android on the example of a simple game
Tatoušek, Petr ; Pecinovský, Rudolf (advisor) ; Oraný, Vladimír (referee)
Demonstration of the Android application development principles explained on a simple game is a thesis describing in it's theoretical part Android OS. It also briefly describes it's history and especially it's architecture emphasizing on my thesis' part relevant to the practi-cal part of my dissertation. It also focuses on the general applications' architecture princi-ples for this operating system. In the practical part of the thesis I tend to describe the application development principles for Android OS. This is achieved on an sample application. This sample application is an implementation of a text-based adventure game in the Java language. It uses SQLite data-base for storing the game data. There is a game framework which enables entering diffe-rent game data to the database and thus playing different games with divergent game plays.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

Specifics of social work with clients with drug addiction
HANZALOVÁ, Vendula
The number of people in the population who use addictive substances and develop adverse life situations is still growing. This issue is also connected with social, health and legal problems with which the drug user must deal. In this case, those addicted can look for help to institutions such as a contact centre. The theoretical part is focused on three topics. The first describes the terms of drug addiction, its origin, consequences and forms of support. The work deals with theories that are significant to the work. The last topic concerns the specifics of social work in a contact centre. There are selected core activities and techniques specific to this institution. I set the aim for this paper, which was to answer the question of which theoretical approach is best applied by social workers working with drug addicts. Furthermore I was finding out which are the best examples of good practical training. The results after evaluation showed that social workers cannot tell whether they work according to particular theories. Usually there is eclecticism, which means that they collect different experiences and then apply them to the work. The basis for these is a bio-psycho-socio-spiritual model that takes into account the integral concept of personality and the philosophy of Harm Reduction which is the main point of contact work. The research brought the views of social workers, their recommendations, and techniques that are proven by them, and also describe the pitfalls of their work. In my opinion, this work could serve as a good summary of techniques for new workers who would like to work with drug addicts. My results can also be the basis for further studies and research in this area.

The GIS support to measures on the ground in case of leakage of liquid pollutant on the road
Kolejka, Jaromír ; Rapant, P. ; Zapletalová, Jana
Accidents on roads associated with the leakage of hazardous substances are one of the major challenges encountered by disaster management. Because of the impossibility of predicting the place and time of the event, then it is necessary in the event of such an accident to proceed in quick succession of steps. They are designed primarily to protect human life and health, and then to minimize to property and environment damage. The paper describes the response to this event using GIS tools and generally available geodata. The simulated accident on the D1 highway near Ostrava is applied as a demonstration example.
