Application of finite mixtures to text document classification
Novovičová, Jana ; Malík, Antonín
Finite mixture modelling of class-conditional distributions is a standard method in a statistical pattern recognition. We proposed to use the mixture of multinomial distributions as a model for class-conditional distribution for text document classification task. The vector document representations using a bag-of-words or a unigram approach are employed. Experimental comparison of the proposed model and the standard models was performed using Reuters-21578 database.

Analysis of the defects identified in the fire inspections performed within the State Fire Inspection of the Fire Rescue Department of South Bohemia for the years 2003 - 2012
KOŠŤÁL, Filip
The thesis on the topic Analysis of Faults Found in Fire Inspections Performed within Execution of State Fire Inspection by the Fire Brigade Rescue Corps of Southern Bohemia in 2003 2012 focuses on comparison of faults selected by gradual elimination from all the 700 fire inspections to final 150 complex fire inspections and classified per years in a ten-year comparison period. Follow-up inspections and thematic fire inspection were not used for the complex evaluation as they did not contain the necessary information. Six parameters were chosen from all the performed complex inspections containing 30 monitored facts of correctness and existence of documents of the inspected object and seven monitored facts from physical examination of the objects. These six parameters were subsequently compared. The aim of my thesis was to find out whether the numbers of the faults detected within execution of the state fire inspection were increasing in the individual categories. The theoretical part summarizes the basic legal norms applicable to the Fire Brigade Rescue Corps of the CR and to execution of the state fire inspection and some extensive legal norms related to the inspection activities or inspected subjects. Elaboration of the thesis topic required explanation of some terms like legal entity, private entrepreneur, fire inspection, state fire inspection and its integration in the Fire Brigade Rescue Corps of the CR. The chapter contains description of activities including graphs illustrating procedures related to execution of state fire inspection. A separate part is dedicated to fire protection history, formation of awareness of the history and to chronological arrangement of some key legal norms binding for the Fire Brigade Rescue Corps of the CR and execution of state fire inspection. It was for example necessary to present the rules governing execution of state fire inspection like professional competence of Fire Brigade Rescue Corps members and their identification at the place of inspection, to clarify the terms fire inspection plan and fire inspection programme. The final part of the theoretical base of the thesis contains the rules of behaviour of Fire Brigade Rescue Corps members performing state fire inspection at the inspected site and principles of interaction with people representing the inspected subject. The research methodology was chosen adequately to the topic dealt with. First archive materials from complex fire inspection records were studied and then the individual faults were qualitatively processed and categorized to faults in documentary part and physical defects. After that a selection of closer spectre of examined faults was performed and preparation of data for comparison. The faults of the individual years were compared in the monitored data and the danger index of the individual years was calculated. The concluding part of the thesis focused on presentation of the dependences of the detected faults of the individual years by means of tables and graphs. The results were mutually compared, classified, commented in detail in the discussion and elaborated into the overall image of the society. Dependence of the number of performed complex fire inspections on the number of detected faults was proven from the danger index and from graphic representation of its values.

Internal equity principle in the context of company strategy
Kopecký, Martin ; Nový, Ivan (advisor) ; Háša, Stanislav (referee) ; Blažek, Ladislav (referee)
The thesis deals with the scientific problem of the link between the strategic management and the compensation system using the principle of internal equity. The work is based on two pillars, namely the qualitative research and own proposed solution. The first part of the thesis describes the qualitative research and the possibilities and the synergistic effects of linking business strategy and compensation system. The qualitative research is performed as a multi-case study and investigates the phenomenon in the practice of three companies from various markets (the Czech Republic, Slovakia and Bosnia and Hercegovina) and industries (finance, IT/Telco and FMCG). The research tries to find answers to the four research questions: How does business strategy influence compensation process? How can compensation support the realization of a business strategy? How can business strategy be linked with a compensation system within the principle of internal equity? How can compensation reinforce the strategic function of the human resources management? The research is based on the study of theoretical sources as well as on practical fieldwork. The qualitative research itself uses qualitative research methods for data collection, such as observations, questionnaires, and document analysis. The population questioned was top managers, line managers and representatives of HR department. In total, 142 interviews were performed by a single person. The collected data were analyzed and the triangulation was applied. The findings were summarized and generalized into a final report that brings answers to the research questions above. The research brings valuable findings used in the second, design part of the thesis. The own proposed solution consists of two main models. The first one is a simplified scheme of the compensation system and the second one is a model of strategic segmentation of jobs. The first model could be used successfully in the business practice as well as in education. The second model of the strategic job segmentation brings answer to the question of synergistic linking of business strategy and the compensation system within the principle of internal equity. The model brings valuable findings and a foundation for further theoretical research and its further development. The model also brings practical solution to the design of related policies and processes in the strategic management of human resources. By the design of both proposed models the main objectives of the thesis were achieved.

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.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.
