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.

Uncovering of rootkits and detection of spyware
Juras, Stanislav ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
Bachelor’s thesis is about uncovering of rootkit and detection of spyware. It describes the basic types of known spyware and rootkits. Section dealing with spyware is especially about a description of each species. In case of rootkit the thesis is mainly about description of modes and the manner of their infection. There are also outlined attempts to use legal rootkit. In other case there are summarized the basic methods of rootkit and spyware detection, which are commonly used in various detection programs. The second part of thesis is practical implementation (the program) of one of the methods of spyware detection. The program is designed to be able to detect a simple pattern of spyware, which is stored in its database. The program uses the file signature detection. It contains also the graphical user interface, where is possible to choose a unit that user want to test.

Měření neformálního sektoru v transformačních ekonomikách použitím makroekonomických metod: nové důkazy
Hanousek, Jan ; Palda, F.
An easy and popular method for measuring the size of the underground economy is to use macro-data such as money demand or electricity demand to infer what the legitimate economy needs, an then to attribute the remaining consumption to the underground economy. Such inferences rely on the stability of parameters of the money demand and electricity demand equations, or at the very least on knowledge of how these parameters are changing. We argue that the pace of change of these parameters (such as velocity) is too variable in transition economies for the above methods of estimating the size of the underground economy to be applicable.

Nursing care of the patients with chronic pancreatitis
SKOŘEPOVÁ, Jana
Chronic pancreatitis is a serious disease, which despite the rapid development of diagnostics and treatment is often diagnosed in late stages. The disease cannot actually be cured, but change of lifestyle and adherence to diet regimen can influence not only the disease course and progression, but also occurrence of complications. This thesis deals with the problems of nursing care of patients with chronic pancreatitis, with the level of awareness of the disease and the regimen measures among patients. It also monitors willingness and ability of respondents to accept the change of lifestyle and diet habits. The goal of the thesis is to find out the specifics of nursing care of clients with chronic pancreatitis. Qualitative research methods were applied in the empiric part of the thesis to achieve the goal.The research was performed in clients with chronic pancreatitis visiting the gastroenterology outpatient department of Tábor Hospital and a group of ten respondents at different stages of the disease were subject to the research. Their selection was conditioned by their willingness to participate in the research and to cooperate. A semi-structured interview was conducted with each respondent. Thorough study of these problems and the results of the research led to a brief and clear information brochure for people suffering from chronic pancreatitis as the output of the activities. This manual should serve as a summary and specification of information, which the patient can read at home without fuss after being educated orally. With regard to the achievements of our work we would like to make this work and its results available to the nursing care public as much as possible. We hope that the results of our work will increase interest in this issue among professionals and will address further workers willing to participate in its solution

Influence of social politics on fertility rate in specific regions of Czech republic
Dvořák, Josef ; Melzochová, Jitka (advisor) ; Babin, Jan (referee)
Thesis is focused on relationship between fertility rate and tools of state support. The goal is to reveal relationship between these two factors. Partial goal is to discover specific effects of tools of state support in specific regions of Czech republic. I have aimed on research at national level and also specific regions between years 1993-2014. In order to find these relationships I used method that compares differences in development of the fertility rate. After that, I set up regression model solved by method called fixed effects. For specific regions analysis was used OLS method. Model was able to explain more than 80 % of variability. This results can be used for predicting of citizens behavior, when some changes in family allowances occurs. Main finding is, that most motivating tools are parenting allowances and child benefits.

Design of heat exchangers for high temperature applications
Jonák, Martin ; Kilkovský, Bohuslav (referee) ; Kermes, Vít (advisor)
This thesis is devoted to thermal-hydraulic design and rating of heat exchangers with the specialized commercial software HTRI. These heat exchangers are solved for real high-temperature applications, where the hot fluid is a flue gas with high temperature (above 500 °C). In the thesis is made a brief analysis of the conventional design of heat exchangers usable for high-temperature aplications, description of the basic relations, description and brief user manual of software HTRI. Further, work includes a comparative study of methods for calculation of pressure drop of the fluid at 180° elbows, as support analysis for solution of required applications characterized by low pressure drop of process fluids.

Human Factor Reliability Evaluation
Richter, Marek ; Tabas, Marek (referee) ; Kotek, Luboš (advisor)
This thesis is focused on evaluation human factor reliability of assembly line, which is in company Hella Autotechnik, s.r.o. from Mohelnice. This analysis will be made with several methods. At first will be estimated operator errors with method TESEO, then will be used method Fault Tree Analysis (FTA) for detection hazard factors, which are influenced by production on the assembly line. In the end will be identified hazard precaution with HAZOP study.

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.
