The structure of supply and costs of cereal biofood in the selected region of the Czech Republic
JIŘÍKOVÁ, Martina
The aim of this bachelor thesis was to evaluate the structure of the supply of organic cereals in the town Sušice. Comparison of the supply of organic cereals was made in different types of supermarkets (Billa, Albert, Penny, Lidl, Tesco and Coop) and in one specialized shop (Meduňka). The differences between the prices of organic and conventional cereal food were evaluated. The survey was conducted during six months, from November 2011 to March 2012. In total, 82 organic cereals were found, most of them were available in Meduňka specialized shop (37). The differences between the prices of organic and conventional cereal foods were significant. For example, in the prices of muesli bars and rice sandwiches, a survey has found that organic prices were 50 to 100 % higher. If someone bought one piece of all the organic cereal food in Sušice, he would pay 1152 CZK. The purchase consisting of one piece of adequate conventional product would cost 760 CZK. It means, that to buy organic products would be more expensive (76 %). It was also concluded, that the supply of organic food in Sušice was lower than the Czech Republic?s supply.

Analysis of retail opportunities and threats in Strakonice region
BAJTOVÁ, Jitka
Principal objective of my authorized work has been to make analyse of retail´s opportunities and threat in section of quick high turnover goods in Strakonice. Information, which has been obtained, base on the analyse and observation, to write to the simulation software RetailOpportunitySim, to introduce screenplay of development and base on the results from the software to propose suitable actions for chosen retail´s subject. To calibrate the software was necessary to define the market geographically and define the real structure of the settlement. Survey was carried out and observations of the retail units on my chosen market. Scenarios were defined hypotheses were confirmed or rejected by software. The scenarios were applied to the retail unit Gastro.

Computational aeroacoustics of human phonation
Šidlof, Petr ; Zoerner, S.
The current paper presents a CFD model of flow past vibrating vocal folds coupled to an acoustic solver, which calculates the sound sources from the flow field in a hybrid approach. The CFD model is based on the numerical solution of 3D Navier-Stokes equations on a time-dependent domain, solved by cell-centered finite volume method. To capture the fine turbulent scales important for the acoustic source calculations, the equations are discretized and solved on large computational meshes up to 3.2M elements. The CFD simulations were run in parallel using domain decomposition method and OpenMPI implementation of the MPI standard. Aeroacoustic simulations are calculated in a separate step by Lighthill’s acoustic analogy, which determines the acoustic sources based on the fluid field. This is done with the research code CFS++ which employs the finite element method (FEM).

Hydraulic calculation of sewage system in Lipůvka
Balas, Jan ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
Diploma thesis is focused on hydraulic assessment of Lipůvka´s sewer system, done by dynamic rainfall-runoff simulation model. Because of this fact, chapter about mathematical models is included. Commonly used programs to this actions are listed as well. Next part of the thesis describes monitoring campaign, which was done in Lipůvka and results are used to calibrate the simulation model. Hydraulic assessment of sewer system by this calibrated model was done.

Optical amplifiers for metropolitan and access networks
Čech, Martin ; Šporik, Jan (referee) ; Tejkal, Vladimír (advisor)
Aim of this Master´s thesis is to describe and compare most common types of optical amplifiers used in today’s networks. The first section focuses on problematic of optical transmissions and phenomenon which cause degradation of transmitted signal. It is also explained in this section why there is a need to deploy optical amplifiers. Next section describes basic principles, structure and properties of individual types of optical amplifiers. Following section describes simulations which were made to compare the performance of transmission systems with each individual type of optical amplifier. The last section contains a design of optical metropolitan network with wavelength multiplex. Based on simulations from preceding part best amplifier type and optimal amplifier placement was selected. Functionality of the design was tested and simulations described in final section.

Tax audit
Amrich, Peter ; Boháč, Radim (advisor) ; Marková, Hana (referee)
The aim of my thesis is the evaluation of tax audit issues and eventually to propose changes de lege ferendae. At the same time I apply the principles of tax audit in its selected aspects. The main aim of the thesis - a complex evaluation of the tax audit - achieved through partial commentaries and evaluations, which are reflected in the titles of each chapter and by using scientific methods such as descriptive method, the method of deduction and applications, as well as the synthesis method and the method of subjective criticism. The logical structure of my thesis is accurately represented by the structure of its seven chapters and several subchapters and its names. In the first chapter I discuss the institute of tax audit in general. In the second chapter I discuss the principles that need to be applied to institute of tax audit. The third chapter deals with stages of tax audits. The fourth chapter is reserved to protection during and after tax audit. Criminal context of tax audit is discussed in fifth chapter. Statistics of tax audit and my conclusions deducted from the statistic data are focused in the sixth chapter. The case law on the tax audit is focused in the seventh chapter. Processing of each chapter is accompanied by my subjective evaluations of individual aspects of the tax audit,...

Condition monitoring of thrust ball bearings using continuous AE
Chlada, Milan ; Nohal, L. ; Převorovský, Zdeněk
Fast and reliable analysis of continuous AE recorded during endurance tests on flat washer parts reliably simulating critical rolling contact fatigue of the full-scale bearings is presented in the paper. Two channels of continuous AE signal were partially recorded within whole specimen lifetime tests and compared with other experimental parameters as vibration rate or temperature. As an alternative to classical spectrogram analysis, we proposed to use histograms of time intervals between threshold amplitudes crossings in various frequency bands represented by the wavelet decomposition. Results obtained on long-time records are discussed, illustrating advantages of proposed AE signal processing, which can be done in real time to observe the processes before the onset of the final damage on the surface of the specimen more precisely than vibrodiagnostics.

Comparative Analysis of Chemistry Education ( Czech Republic - Scotland)
Laburdová, Jiřina ; Klímová, Helena (advisor) ; Teplý, Pavel (referee)
Key words: Scotland, Czech Republic, education system, Chemistry education, Chemistry teaching, National Qualifications, Standard Grade, Intermediate, Higher, Advanced Higher Abstract: The education system in the Czech Republic is currently undergoing many changes. Education systems of foreign countries are often what inspire us to make these changes. The aim of this thesis is to describe the education system in Scotland and the way chemistry is being taught at secondary schools in this country. Further it tries to compare these to the education system and chemistry teaching in the Czech Republic and consider whether we can adopt any aspects of Scottish education. Apart from analysis of study plans and educational documents, research for this thesis included visits to chemistry lessons at three secondary schools in Scotland and interviews with teachers at these schools. In the text, cultural and historical context of Scotland related to the education system is mentioned briefly. Then the Scottish education system is explained and Chemistry teaching at secondary schools is described from the point of study plans and requirements. The following chapter contains a description of schools that have been visited, together with reports from selected chemistry lessons. Last chapter then compares various aspects of...
