Parametric testing plasma welding on the root of weld
Záškoda, David ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
The subject of this thesis is to assess the suitability of the new process of welding roots of welds by the rotors of steam turbines plasma jet. The new proposed method uses a combination of welding the weld root plasma with the method of submerged-arc welding, however the submerged-arc welding is not subjekt of this work. The tests performed were verified by the possibility of welding the weld root of the plasma jet – Keyhole method without filler material. The aim was to find the optimum welding parameters to achieve the required weld quality, particularly with regard to geometry of weld. Turbine rotors are made of heat resistant steels, which have high strength at high temperatures. In all described tests have been used steel 30CrMoNiV 5-11....Mat. No. 1.6946.

Irrationality in the decision- making of an individual as an economic entity in the territory of the Czech Republic
Böhm, Tomáš ; Zeman, Martin (advisor) ; Babin, Jan (referee)
The main objective of this thesis is an in-depth analysis of the decision-making process on issues of economic nature for individuals in the Czech Republic. The degree of rationality occurring in consumer behavior is evaluated based on lessons learned. The theoretical section is concerned with the economic aspect of the decision-making process, which mainly includes knowledge of neoclassical theory, whose basis is the cardinal and ordinal concept of utility maximization. Subsequently there are introduced the alternative approaches to decision making, focusing on the subjective aspects of human reasoning. Using the mutual synthesis of these approaches, the author draws a term behavioral economics, specific elements of which constitute a substantive content of the whole work. The practical section verifies the hypothesis that the decision-making contradicts the theory of rational individual conduct. Data collected through the questionnaire is subjected to analytical procedures by which the stated hypothesis was verified.

The value of life from macroenomic point of view in United States of America, Czech republic and Russia between years 2007-2014
Antoš, Michal ; Zeman, Martin (advisor) ; Brabec, Petr (referee)
The subject of this bachelor thesis is the research of the value of life calculation in the Czech republic, United states of America and Russia in 2007-2014.The main purpose is to analyze and compare values of life and major factors influencing them. The hypothesis is that value of life differs in selected countries due to distinctions of sections influencing them. The theoretical part is devoted to sections directly or indirectly influencing values of life, and then analyzing and comparing them together within the selected countries. The selected sections are education, health care, labor market, inequality and living standards. The practical thesis approach is to calculate the values of life for the individual states. The values of life are calculated for so called, representative individual, who is 40-years old citizen of selected country. In the period, in which is the value of life calculated, the retirement age and life expectancy are also considered in formula. Calculated values are examined and the economic and political measures are offered to the states, which can turn into significant increases in the value of life in future.

Fiscal rules in selected EU countries between 2004-2015: sensible method for consolidation of public finances or fad of politicians?
Veselý, Lukáš ; Strejček, Ivo (advisor) ; Chmelová, Pavla (referee)
The subject of fiscal rules is very topical issue. The rise of public debt in certain developed countries resulted in what is sometimes called "debt crisis". Debt of those countries which is higher than their annual gross domestic product is viewed as unpayable by some economists. The main objective of this thesis has been to prove or disprove hypothesis that the fiscal rules studied in this paper are an effective solution for public finance consolidation. This verification was based on the analysis of fiscal rules functioning in selected countries between 2004 and 2015. As per results of analysis the paper aims to give recommendations for the Czech financial constitution proposal. The actual results of inquiry proved the hypothesis. Well-chosen fiscal rules are the right way towards fiscal consolidation, provided they are observed. Fiscal rules making thus requires an emphasis to be placed on the well-formulated exit clauses altogether with prospective sanctions. The current Czech financial constitution proposal is built on the correctly picked fiscal rule type, although the reference value lacks economic sense and it would not lead, with a high degree of probability, towards fiscal consolidation.

Ježová, Jana ; Svobodová, Ivana (advisor) ; Srpová, Jitka (referee)
The aim of this thesis is to create a business plan for the newly established business subject in the health food industry and evaluate the viability of the plan. The plan also includes the choice of the appropriate form of potential expansion into the foreign market. This thesis is divided into theoretical and practical parts. To create this business plan, firstly it was necessary to write down the complex theoretical framework of the basic aspects which are crucial for small and medium businesses. Secondly, it was needed to sum up the general principles of creating a business plan, characterise its structure and mention the most common mistakes and problems that entrepreneurs may encounter. The theoretical part is concluded by a description of the appropriate forms of expansion for small and medium businesses. Based on this theoretical framework the business plan for the company SnackBag was created with the emphasis on the project´s financial calculation. The calculations confirm the business plan as viable. Analysis of the main advantages and disadvantages of particular forms of expansion to foreign markets concludes that the franchise was evaluated as the most suitable for SnackBag.

"European Identity" of a Teacher
Gröschlová, Andrea ; Walterová, Eliška (advisor) ; Chvál, Martin (referee) ; Janík, Tomáš (referee)
This work attempts to identify and analyse factors that have an effect on the identification of teachers with Europe: "European identity" of a teacher is being argued. We widely discuss actual meaning of the term "Europe" and seek an empirical approach to the "European identity" research. Correctness of the "European identity" of a teacher is not put to test; actual issue of the teacher's profession is being discussed instead. The structure of this work consists of three chapters. First of all some basic assumptions for the work need to be posted: we discuss such terms as "globalisation", "knowledge society", "educational aims" and context of "European dimension of education". The second chapter presents three interrelated parts. They are focused on the meaning of theme "teacher as a subject of research", "identity as a subject of research" and "Europe as a subject of research" . We conclude with the own meaning of the "European identity" of a teacher in the end of the second chapter. Empirical approach throughout the rest of the work is based on this conclusion. The methodological approach is derived from the character of the postulated hypothesis. We compare two independent samples. Two samples being a) teachers (teachers of basic and secondary schools in Prague) and b) random population. Based on the...

The language and the world. Literary and art work of Jiří Kolář
Gemrothová, Adéla ; Špirit, Michael (advisor) ; Vojvodík, Josef (referee)
The literary and art work of Jiří Kolář make one integral entirety. Built up by one author's concept, specific artistic intention, which manifest itself as coherent in operation with different meidums of expression at the sphere of naturallanguage as well as at the sphere of visual images. There is in a same way apllied a princip of paraphrase and variacy, a multiplication of perspective, exploitation of authentic, assumed material, citation, aleathoric princip etc. Kolář is aimed at evident character of a reality and at the matter, how we experience it by understanding a world, particularly through the mediation of language. This effort motivate a permanent searching for a divers constructives methods. So the subject of author (a speaker), instead of own artistic representation ofworld, constitute a pluralistic, multilateraů work, which inquire possibilities of an attitude between a work of art and a real world, his participation on it.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.
