Luštěniny jako zdroj vybraných makro a mikronutrientů
Bernreiterová, Hana
This diploma thesis deals with the determination of amount of selected mineral elements (Ca, Mg, Fe, Zn and Cu) for eight species of pulses: Cicer arietinum L., Glycine max L., Lens culinaris Medic., Phaseolus vulgaris L., Pisum sativum L., Vigna angularis L., Vigna radiata L. a Vigna unguiculata L. The differences between species in the amount of selected mineral elements and the dependance of the amount on the method and location of growing were determined by atomic absorbtion spectroscopy. The results determined that the best source of selected mineral elements is soybean. On contrary the least useful source is pea. Consummation of common bean and Vigna species is beneficial because of high amount of calcium and magnesium. Except soybean the high amount of ferrum, zinc and copper is in lentil. There was no general difference in amount of selected mineral elements based on location and method of growing.

Feed-forward neural networks and their application in data mining
Civín, Lukáš ; Štanclová, Jana (referee) ; Mrázová, Iveta (advisor)
The goal of data mining is to solve various problems dealing with knowledge extraction from huge amounts of real-world data, the quality of which might be disputable. Neural networks can help with the solution due to their generalization capabilities. While working on data mining projects, we have essentially the following two objectives in real-world applications of feed-forward neural networks. To obtain applicable results, it is crucial to provide the networks with well-prepared data. However, it is equally important to choose the right training strategy for the networks themselves - including network architecture, parameter settings or the training algorithm. One of the most important ideas behind these steps is namely to prevent "over-training". The final network should recall unknown examples as well as possible. There are plenty of techniques with different approaches to the solution. It is possible to modify the data, these comprises modifying the range of the data or its dimension, adding noise to the data, etc. Yet another way is the modification of the neural network by structural learning with forgetting, weight decay or early stopping. These techniques are analyzes both theoretically and experimentally in this thesis. With regard to the results achieved in a number of experimental tests we have...

Kubásek, Petr ; Gardášová, Alena (referee) ; Klika, Pavel (advisor)
The objective of the thesis is to determine the economic rent amount for a family house located in Brno. The concept “economic rent” refers to the amount of payment that brings adequate profit to the landlord. First, all the factors are identified that compose cost rent, i.e. the rent of mere providing and maintaining a property. The main variable is represented by the reproduction value of a dwelling. For the purposes of this thesis, the reproduction value is determined using the cost method (in agreement with the evaluation regulation). Second, the capitalization rate is determined so that an adequate profit could be calculated. The following two methods are employed: the surcharge method and the method of comparison with the financial market. The thesis presents seven alternatives of an economic rent, depending on the interest rates. Lastly, the calculation of the rate of return is performed, along with a correctness test of the calculation of the economic rent amount.

Possibilties of the use of an automated warehouse in a chosen food processing company
ROČEJDLOVÁ, Lenka
The bachelor?s thesis topic is ?Possibilties of the use of an automated warehouse in a chosen food processing company?. It focuses on the present functioning of the automated warehouse in Budějovický Budvar, n. p. The solution of the problem of 5% rejected products into the automated warehouse due to packaging defects was proposed on the basis of discovered facts. The proposed system of the solution succeeded to eliminate the problem of 5% of rejected products into the automated warehouse. The most suitable alternative was chosen on the ground of the cost analysis of the particular solutions. It is necessary to ensure the possibly highest quality of the performed work in the phase of packaging due to increasing wage costs and the need of the company to effectively handle the costs in the future. Only adequate controlling can ensure it. Currently, the packaging quality control is set to the moment of receiving the products into the automated warehouse. In this way, the defect cannot be eliminated on time, it can only be notified. The solution informs about the possibility of a defect in time when it can be eliminated easily and without additional costs right by its origin. The shift of the control to the packaging phase depends only on time and on the amount of additional cost for the control launch compared to the costs of the repeated packaging.

Přirozená obnova a produkční potenciál borovice vejmutovky (Pinus strobus L.) v oblasti Městských lesů Hradec Králové
Vaněk, Petr
This dissertation thesis deals with two aspects of Eastern white pine. The first objective of this research was to evaluate the effect of the amount of solar radiation on the parameters of natural regenerated Eastern white pine individuals -- density, height, stem diameter, height increment and crown morphological parameters. The second objective of this work was to compare the production potential (stem volume, stock) of Eastern white pine and native Scots pine. For both purposes were selected forests stands with appropriate representation of Eastern white pine in Hradec Králové municipal forests. For the first objective study showed that the amount of light is a key factor in relation to Eastern white pine regeneration. Increasing amount of light significantly affects both density and growth parameters (height, stem diameter, height increment) of natural regenerated individuals. Effect of light on crown morphological parameters has not been proved. For the second objective evaluation of data showed that same old Eastern white pine in the same habitat reaches significantly greater stem volume than Scots pine in the order of several tens of percent, depending on the age of forests stand.

Multiple life insurance and group insurance
Broukalová, Jana ; Bílková, Diana (advisor) ; Zaderlíková, Šárka (referee)
This thesis aims to familiarize the reader with the topic of life insurance, especially insurance taken out for more people. Its focus is empirical rather as combining the use of several actuarial and statistical methods through three statistical software and applications created in MS Excel using VBA. First, thesis is focused to multiple life insurance with intention to show reader the diversity of this interesting but rarely offered product in business world, especially through the application created for the purpose of this work. Sense of mentioned application lies in the fact it is able to calculate amount of the net premium for a user-selected type of insurance. Based on this outcome insurer can determine the net price corresponding to the chosen risk coverage (regardless of the amount of the costs associated with this type of insurance and required profitability). Age of insured person isn't usually part of calculation of premium for accident insurance. One of the aims of this study is to assess whether this parameter actually has or doesn't have any effect on the price of insurance. With help of SPSS and RStudio software relationship between age of insured person and amount of indemnification from daily compensation insurance has been researched. Based on the test of variable independence were detected dependencies of these variables where all of which used measure of association suggests a weak dependence amount of indemnification on the age of the insured. It surely worth insurer should consider different insurance rates for various ages of insured person. Following by examination whether the rate used to calculate premiums in case of hospitalization extra insurance corresponds to the actual risk coverage. It has been calculated the rate could be lower than currently used due to the loss experience of insurance for the past 9 years and the assumption of certain expenses and desired profit. It would be cheaper for insurance group contracts than it is today, when the insurer has done so. It could also attract new clientele. The last stated goal in this thesis is to create prognosis of the amount of indemnity paid for injuries covered by additional daily compensation insurance. Using the software EViews is analyzed this trend in the past 32 months first. Based on its outcome there is a future level forecast created for the next four years. These resulting values indicate the insurance indemnity for group contract will grow. Therefore, based on this analysis insurer should to conclude in the contract it would be appropriate to increase the premium of the insurance coverage. With these practical tasks the reader can get idea not only of problems solved in the scope of multiple life insurance and group insurance but also to become familiar with some statistical software used for analyzes carried out not only in the insurance industry. The conclusions of this thesis can also be beneficial for insurer who may adjust premium prices of analyzed insurances.

An impact of organic farming on soil quality
Matěchová, Martina ; Jakšík, Ondřej (advisor) ; Janků, Jaroslava (referee)
This work focuses on the system of organic agriculture and its impact on soil quality. It compares organic farming system with conventional. Both these systems are briefly described. There is also a list of soil quality indicators used for the soil quality is evaluation. The results of scientific studies, which dealt with different farming systems and their effects on soil properties, were discussed and evaluated.
Quality and fertile soil is crucial for production systems, however to define what means quality soil is very difficult. Therefore the number of quality indicators were established. The indicators can be grouped by their nature of soil properties they assess, such as physical, chemical and biological. Different techniques are adopted for soil quality evaluation.
Soil quality is affected by a lot of different factors. Anthropogenic activities are often considered as one of the most influential factor. The loss of soil fertility as well as other physical, chemical or biological deterioration of soil properties is called soil degradation.
The results of this study shown that careful tillage in organic farming could have positive effect or no effect on the biological and physical properties of soils. For some experiments there was an increased amount of soil organisms.
In the most experiments, application of organic fertilizers caused increase of organic matter and other essential nutrients. We conclude that under certain conditions with respect for the principles of organic farming the soil quality can be preserved or even improved, but in a longer timeframe.
