Determining the plasticity of mannitolum
Votava, Jakub ; Špaček, Vladimír (referee) ; Řehula, Milan (advisor)
The visco-elastic characteristics and knowledge of them are the important factors that influence pressability of materials. These characteristics differ for every material and it is possible to determine them by variety of methods. In our thesis (chapter Experiments) we evaluated the relationship "force - travel" and determined elasticity and plasticity of materials. The test of relaxation of tense is another way to determine plasticity of materials. The results are parameters of FminA, FminB, FPL and parameters of single-parametric equation that describes decrease of preassure in a tablet during the relaxation period. These parameters and their evaluation are the goal of this thesis. We determined the Young's modulus of elasticity from the tablet dilatation measure restults. The value of Young's modulus of elasticity for mannitol is 413,36 MPa. The value of total plasticity Pc is 91,34177 MPa.s. Generally: increasing value of total plasticity determines increase of tablet material pressability.

Conditions of failures generation when bending profiled tubes
Fišar, Luboš ; Peterková, Eva (referee) ; Samek, Radko (advisor)
The thesis describes the knowledge from a round tube bending technology, as a description of conventional and unconventional devices. There are technological parameters in relation to the creation of defects, and equations for determining the bending moment. These knowledge has been generalized and applied to solution the changes of cross-section shape and thickness in the bending of square cross-section. The solution was implemented to specific component (20x2 mm steel tube with two successive radii R57,2 and R131,5). The results of experiments shows that the material is almost rigid-perfectly plastic, in the most stressed areas has a sufficient supply of material formability. Thickness measurement was applied to calculate the approximate center of gravity changes. This shows a shift of 1.4 mm, which is negligible value for the pure bending. The end of the thesis summarizes the deficiencies of current manufacturing technology, which used mandrel is inadequate, wrong located and poor lubrication.

Osteoporosis - radiologic aspects
DAŠEK, Oldřich
OSTEOPOROSIS is a serious generalised bone disease which results in their increased fragility. It appears in the highest rate at older age. Goal Getting familiar with osteoporosis and comparing radiation doses of patients in case of kyphoplastics and vertebroplastics. Comparison of doses on different equipment and among different methods. Effort to cut down doses for both a patient and attending staff on the performance. Methodology In 2007, care was given to 46 patients in our station using percutaneous vertebroplastics and kyphoplastics. An angiographic set (Siemens - axiom artis) and a mobile C-arm (Ziehm - exposcope 8000) were used to navigate the action for 30 and 16 patients, respectively. The measured doses were assessed for the patients, average doses for vertebroplastics and for kyphoplastics were calculated, and these were compared one against the other. We also assessed the dose in relation to the number of treated vertebra for a single patient and anatomical zones of position of these vertebrae. And finally, we determined the average doses for the instruments and compared them one against the other. Results The lowest doses have been achieved in treating vertebral bodies of TH spine, and the highest value appeared in the performance when three vertebrae have been treated together. The results from comparison of the average dose on both instruments show that the average dose of a patient navigated with the angiographic set is by some 55 % lower against patients with the C-arm used. The value measured for kyphoplastics is by some 50 % lower than for vertebroplastics. Conclusion The results of the study show that kyphoplastics is more desirable concerning the dose, but the economic view is against, as well that it suits rather to acute fractures. The benefit of this work is the comparison of the doses for the surgeries on two types of instruments. We have shown that the selection of the suitable instrument can have impact of the resulting dose for the patient, as well the dose for attending staff. In our case, the effect was up to 55%. The outcome will be the effort to perform the maximum of these actions using the angiographic set and to minimise the total dose.

Vztah mezi rizikovou prémií a ratingovým hodnocením
Závojko, Tomáš
This bachelor thesis deals with the determination of risk premium in foreign direct investment. If investors decide to invest, they need to know how much risk they take. To be a profitable investment, its value should correspond to the premium that investors expect for risk-taking. Through the adjusted net present value of an investment that includes discount rate can be detected risk premium. This work is deals with two methods of calculating the discount rate. In the first method we can determine the risk premium of the real interest rate, in the second method is contained the risk premium in model CAPM. Both approaches use the sovereign rating, whereby I can obtain general results for each rating group. In conclusion I deal with the relation between the risk premium and rating, where I find, if with declining sovereign rating is growing the risk premium and what type of growth it is. Should also be compared these two methods of calculating the discount rate and it will be found, how sovereign rating reflects the risk incurred of investing in the context of foreign direct investment.

Reference functions and values
Marek, Pavel
The current structural reliability assessment criteria (corresponding to the prescriptive Limit States Design concept such as Eurocode and AISC-LRFD) are expressed by comparing the specified maximum load effects and minimum specified resistance. In the qualitatively different gradually developed probabilistic reliability assessment procedures(applicable in codes) clear definitions of the „reference“ functions and values applied in the calculation of the probability of failure must be specified and adequate target probabilities must be given considering tolerable risk, economical requirements and some other measures.

Influence hematological and biochemical parameters by different dogs.
Pechová, Eva ; Fučíková, Alena (advisor) ; Václav, Václav (referee)
The topic of this diploma work was to evaluate the hematological and biochemical indicators of various breeds of dogs. The aim of this work was to evaluate the blood samples taken
from 10 dogs and 10 bitches of various breeds and find out the dependency of values
in relation to their age, nutrition and sex. The samples were processed and evaluated from May to October 2015. The following was examined from the hematological indicators: RBC, HGB, HCT, MCV, WBC and a blood smear was made, from which a differential count
of leucocytes was made. Furthermore, the following biochemical indicators were examined: TP, GLU, CHOL and ATP. The literature research first focused on the basic components
of dog feed. Moreover, the hematological and biochemical indicators of blood as well as the methodology of the whole experiment were described. The results were processed with the aid of the RStudio program and the following basic statistical characteristics were counted: median, minimum, maximum and standard deviation. The ANOVA statistical method was used, in which the dependency of values among sex, age category and the type of feed fed
to the animals was determined. Furthermore, the values among the breeds were compared. From the differences observed among the breeds, there was an increase in red blood cells
in German Shepherds and Dobermans. Dobermans, Labrador Retrievers and German shepherd crossbreeds had increased values of ALT. Significant findings showed that there was an increase in the number of red blood cells and hematocrits in subjects fed with granulated feed as opposed to subjects with a combined diet. The difference was also observed for MCV between the genders.
Differences between the genders were found for ALT values. More data would be needed
to confirm the relationship to age. ALT values are dependent on the type of feed, where the values are higher in subjects fed with a completely granulated diet. The values of total protein increased in dogs with age. This trend is likely to be observed in bitches. For subjects fed a combined diet (granulated feed + home diet) an increase in the value of total protein was observed with age. For subjects fed granulated feed, this increase was not as significant.

Possibilities of Deepening the Theory and Practice of Investment Decisions with an Emphasis on Real Options
Oceláková, Petra ; Valach, Josef (advisor) ; Hrdý, Milan (referee) ; Choulík, Petr (referee)
This dissertation deals with selected areas within capital budgeting theory and practice. The first part is focused on possibilities how to improve traditional financial metrics as net present value and internal rate of return by using graphical tools for their interpretation. The main practical problem can be considered not the methodology itself, but the inability to predict future cash flows correctly. The special attention is paid to depreciation in connection with Czech accounting and tax legislation and its influence on capital decisions. The second part of the dissertation concentrates on real option analysis. The crucial difference between net present value and real options analysis is in how these methods deal with the risk. Mathematical approach is used to derive how the volatility and other parameters affect the theoretical value of an investment determined by real option. The more volatile the future cash flows are the higher theoretical value of the real option should be. Nevertheless, there are some exceptions that are analysed in this paper. In final chapter, total cost of ownership and real option analysis are used to evaluate option to switch from on-premise IT solution to cloud computing.

An Effective System of Remuneration In the Public Sector
Picka, Jakub ; Kubátová, Květa (advisor) ; Izák, Vratislav (referee) ; Malý, Ivan (referee)
Expenditures on the salaries of public sector employees constitute a very important component of public expenditures, currently around CZK 200 billion annually in the Czech Republic. Adjusting the remuneration of employees in public administration (sector) is therefore an important option for increasing the efficiency of use of public funds. The assessment of the current system of public sector employee remuneration and a proposal for some specific changes to be made to it is the focus of this dissertation. The primary aim of my dissertation is to analyze the system of remuneration of employees of public and private sectors, both qualitatively and quantitatively. Within the primary target there is also a decomposition analysis, which indicates whether the employees are discriminated against in any of the sectors. The secondary objective is to make recommendations for the system of remunerating public sector employees of the in order to increase its efficiency in terms of public spending while maintaining its incentive function. The work is divided into five chapters. The first chapter, entitled "Theoretical Foundations," provides an overview of the relevant literature, the fundamental basis in economic theory, and issues of the Mincer wage equation, which is then later used as the basis for regression and decomposition analyses, and mainly describes in detail the decomposition method that is used to explain the difference in the salary level in the private and the public sector. These decomposition methods represent, together with quantile regression, the main tool used to meet the objectives of this work. The second chapter, entitled "The Remuneration of Public Sector Employees," describes the structure of the remuneration of employees of the public sector. The data shows that the current system produces results in the form of salaries that do not correspond to the market. The third chapter, called "Regression Model," builds on the analysis performed on data from QSAE, which was discussed in the second part of the previous chapter, and its purpose is to prepare the documents for verification and deepen their conclusions. The fourth chapter, called "Regression and Decomposition Analysis," is based on the regression model assembled in the previous chapter, and describes the results of the regression decomposition analysis performed on the described sample data. This chapter verifies the hypotheses set out in the introduction and answers research questions. The fifth and final chapter, entitled "Interpretation of the Results and Recommendations," focuses on the interpretation of the results, the proposed regulation of remuneration, and recommendations for further research. The main finding of this work is that the system of remuneration of public sector workers is set so that, while the overall average brings quite comparable results in terms of the salary as the entire labor market, it is not throughout the distribution. The performed regression analysis showed that both the public and private sectors evaluate the same things differently (different values of the regression coefficients of variables), and both at the average and along the entire distribution. We can say that the mechanism of the remuneration of employees of the public sector is different from that of the market. This fact is confirmed by the significantly higher coefficient of determination of the regression model of the public sector. Regarding possible discrimination in wages, the analysis showed that employees in the public sector may in contrary to the preposition of positive discrimination be positively discriminated against only up to approximately fifteenth percentile. From fifteenth percentile they are discriminated against negatively. This was confirmed by the decomposition analysis performed on the average salaries, which indicates that public sector employees are, at this level, negatively discriminated against (if the public sector employees have the same regression coefficients as private sector employees, their earnings increase). Finally, this conclusion is confirmed by the dummy variable, which represents belonging to the private sector when the value of its corresponding regression coefficients, in quantile regression analysis along the distribution, evolves from negative to positive and is significantly increasing. The thesis also shows how the system of remunerating public sector employees can be adjusted to reward employees in a way that is comparable with the market.
