The protection of personality and CCTV systems.
Orság, Oldřich ; Cvik, Eva Daniela (advisor) ; Jan, Jan (referee)
This thesis is dedicated to the protection of personal details in the Czech Republic because it permeates the entire legal order and infringing on privacy is a fundamental right in the Charter of Fundamental Rights and Freedoms. The aim is to analyze the development and current state of protection of personality and the right to confront with the city camera supervision system indulging city police in the Carlsbad region. In the Czech Republic there is a collision of two components of fundamental rights and freedoms, the right to privacy and the right to safe living in society. Clash of these two components law is being compared under different regulations. The work is based on the decomposition of laws in force in the Czech Republic and subsequent research by municipal police Karlovy Vary region.

Influence of texture of briquettes from biomass to their mechanical properties
Černá, Iva ; Pecen, Josef (advisor) ; Jan, Jan (referee)
With the rising amount of AD technology utilizers, the issue how to storage, such liquid material, which digestate is. In recent time, there are some other ways to utilize it, except fertilizing with liquor, liquid part of digestate. Digestate can be dried and pressed into briquette or pelleted form. In briquette form is important to understand relations between properties of individual components because one property can influence another one, which constituting texture of the material and its reprocessing into the final form of the product. Thus this study was conducted, to find and/or quantify the relation between the texture of biomass briquettes and their durability and strength of shape during manipulation, storage and use. Basic hypothesis of this work is based on open presumption that briquette texture is dependent on many parameters. Some of those parameters were tested. Namely, composition of matter, physical properties of digestate briquettes, durability and hardness, size analysis and other. Digestate has approved as good material for compression with high content of nutrients. The rate of abrasion varied 7-12% at the beginning decreasing to 3-5%. Shore testing showed results predicating relation between particle size and hardness. Sieve and image analysis then showed range of particles ranging size 0.01 mm from 99.5% and 10 mm from 99.7%, most of them with needle-like shapes. This study suggested the method that allows analysing particle size distribution in sample and describes other briquette properties, which can be useful for next research and commercial purposes.

Effect of linoleic and α-linolenic acidis in pig nutrition on quantity and quality of intramuscular fat of pork with emphasis on the n-6/n-3 PUFA-spectrum
Vehovský, Karel ; Stupka, Roman (advisor)
Human nutrition is a function of nutrients' intake from food. The essential nutrients needed by the human body to produce energy, growth and repair of cells, tissues and organs and which accepts in the human diet, are fats. They are obtained from plant or animal sources. Especially animal fats are often ranged among the unpopular food components. Czech Republic is a country with traditionally high consumption of pork. Recently, about healthy foods greatly increase the interest. These include some animal products having an altered composition of fatty acids in fats. The content and composition of saturated and unsaturated fatty acids in human nutrition are important for protecting of human health. The high content of saturated fatty acids in foods and unfavorable ratio between the n-6 and n-3 fatty acids may be the cause of many diseases, especially cardiovascular diseases. Fats in the diet should contain saturated, monounsaturated and polyunsaturated fatty acids, in a ratio of about 1: 1.4: 0,6. From a health perspective, the most important are the n-3 polyunsaturated fatty acids. Animal fats, however, contain sufficient n-6 polyunsaturated fatty acids, n-3, however, a little. Pork meat quality from the viewpoint of fatty acids composition is currently not very favorable. Significant effects on the fatty acids profile of animal fats have the fats in the feed. It is thus the possibility of by using the diet to influence the composition of fatty acids in the fat in pig. The work is focused on the possibility of influencing the fatty acids composition of pork intramuscular fat using supplementation of different sources and different feeding techniques of unsaturated fatty acids in the feed in pigs. In the experiment, as a source of unsaturated fatty acids the supplement of the rapeseed or soybean oil was used. The results demonstrate that the above unsaturated fatty acid sources significantly changes the fatty acid composition of intramuscular fat.

Strategy of the Innovations of Vehicle Inspection Emission Stations
Marušková, Helena ; Růžička, Miroslav (advisor) ; Tichá, Ivana (referee)
The doctoral thesis Strategy of the Innovations of Vehicle Inspection Emission Stations is engaged in marketing strategies and innovations of the vehicle inspection emission stations in the Czech Republic. The theoretical part is dedicated to the references and describes marketing environment, SWOT analysis, marketing strategies, marketing mix and several "P". It also focuses on the innovation and innovation strategies, the different types of marketing research, the exhaust emissions of combustion engines, the homologation regulations and the periodic emission measurements at the vehicle inspections emission stations in the Czech Republic and in the world. The aim of this thesis is to describe and analyze the current situation and work up a strategy of the innovations of vehicle inspection emission stations. The practical part is devoted to analysis of the marketing environment (PEST analysis and the microenvironment), from which a SWOT analysis of vehicle inspection emission stations and further describes the individual components of the marketing mix SME. The chapter Marketing research SME is divided into quantitative and qualitative marketing research, which lists the various questions, charts and answers resulting from marketing research. Quantitative research is conducted through a questionnaire survey and qualitative marketing research obtains answers based on structured interviews. The paper concludes with several suggestions of the innovation, evaluation of research questions and a summary of the individual chapters, which shows that too stringent emission limits will not lead to their real reductions. Regular tests for SMEs are set up properly and does not need to be changed. Creating a central information system (one for both STK and SME) and the implementation of video surveillance - these changes are needed not only for technical inspections stations, but also emission inspection stations. Due to the increasing number and age of vehicles and especially the fact that the current emission tests of vehicles in no-load mode engines are not able to detect all faults, the new methodology of measure emissions is needed.

Evaluation of the effect of radiation on evapotranspiration estimates and drought indices
Mairich, Pavel ; Matula, Svatopluk (advisor)
Abstract Evaluation of the effect of radiation on evapotranspiration estimates and drought indices The severity of drought can be inferred from water balance, of which evapotranspiration is a component. The evapotranspiration estimates are often based on the FAO 56 methodology with the net radiation as the main input. Usually, however, the latter is not directly measured. This study investigates to which extent can the direct solar radiation and the long-wave net radiation measurements be replaced by calculation according to FAO 56 with constant or locally optimised radiation coefficients or, for the long-wave net radiation, the coefficients according to Penman (1948). The problem is demonstrated on data from the Solar and Ozone Observatory in Hradec Králové for 2011 and 2012. On average, the estimates of solar radiation are satisfactory even with the standard coefficients and can be improved by local optimisation of the coefficients. The estimates for particular days may considerably differ from reality. The long-wave net radiation estimate according to FAO 56 is, on average, by about 30 % lower than the measured long-wave net radiation or an estimate thereof based on locally optimised or Penman's coefficients, with the average differences between any two of the last three methods much smaller (less than 9 %). The inaccuracy of estimates for particular days is considerable, too. The average reference crop evapotranspiration according to FAO 56 with standard coefficients is therefore considerably higher (by about 15 %) than analogous evapotranspiration obtained from the measured radiation or according to FAO 56 with optimised or Penman's radiation coefficients. The cause is that grass in the observatory was not irrigated. It therefore occasionally suffered from water stress and got overheated. The use of FAO 56 with the radiation inputs measured or calculated using other than the standard radiation coefficients may underestimate the evapotranspiration and the need for irrigation.

Analysis of water requirements of the field crops in areas with frequent occurrence of drought.
Zábranský, Petr ; Soukup, Josef (advisor) ; Jan, Jan (referee)
Summary Water resources are an important part of ecosystems. In the water balance of the landscape, the variability of climate, soil factors, as well as high diversity of vegetation play an important role. Evapotranspiration represents a major passive component in the water balance of the basin. Unlike forests, where the water balance is particularly predictable due to the long-term development of the stands, regular crop rotation in agricultural systems and agricultural practices may cause rapid changes in water balance during much shorter time. It may sometimes result in irreversible changes in ecosystems with impact on landscape biodiversity. An understanding of the limiting environmental factors and exact determination of the water demands of plants makepossible not only an improvement of yield parameters, but it is also condition for understanding of the agroecosystems sustainability in the cultural landscape. Field measurements of actual evapotranspiration were carried out in the period 2007 to 2015 in Velvary (Budihostice) in the Central Bohemia region, 210 m above sea level in the rain shadow area around Slaný territory. In terms of the average annual water balance (CHMI, 2014), the locality is regarded as the area with the difference between the average annual precipitation and annual potential evapotranspiration totals in amount of -200 mm, so the potential evapotranspiration slightly exceeds precipitation. Field measurements were conducted on commonly managed areas with a minimum size of the experimental plots of 1 ha. The measurements confirmed differences between the crop water demands during the growing season. Different values of the actual evapotranspiration as well as the Bowen ratio values were estimated for the observed crops depending on the growth stage of crops. The lowest values of actual evapotranspiration were detected for Zea mays and Sorghum bicolor. Higher water demands were shown by Triticum aestivum and Hordeum vulgare. On the contrary, the highest values of actual evapotranspiration were found in stands of Beta vulgaris and Medicago sativa. According to the values obtained for crop coefficients (Kc), the crops of Z. mays, S. bicolor and T. aestivum had about a quarter lower values of Kc compared with M. sativa and B. vulgaris crops in the main growing season. In this work, the daily values of Kc, which are the basic characteristics of moisture requirements for individual crop were determined and can be used modelling of hydrological processes in agro-phytocoenoses. The evaluation of moisture requirement of crops by the water flow in plants (determined by the sap flow method) showed the expected differences between S. bicolor and Z. mays plants. Water use efficiency (WUE) was significantly higher in plants of C4 type (Z. mays and S. bicolor) compared with the rest of observed plants of C3 type (T. aestivum and H. vulgare).

This dissertation thesis is focused on bulk unsolicited messages which are present in current time in all sectors of electronic communications. It is not only e-mail communication, but also in online forums, discussion contributions, social networking and more. Analyze spam messages is therefore an essential element in preventing flooding user mailboxes. Antispam countermeasures is a set of processes, software tools and methods. It is necessary to harmonize all these components into one cooperating piece of service. Administrators of email servers are trying to keep their servers optimally configured. The problem is that spammers trying continuously these defense mechanisms and filter bypass to enhance spam processes. Their work is very sophisticated and this fight does not yet have a clear winner. After enhancement techniques either processes takes place after a certain time to balance the advantages and disadvantages. For these reasons it is necessary to have a tool which can be analyzed in depth junk messages with dynamic data views. This tool can be Online Analytical Processing (OLAP below), which is very suitable for this purpose. Presented a method of data extraction and transformation and preparation for storage in a warehouse DT-MEZ (Data Pump - metadata email messages). This method is part of the methodology ASOLAP (Antispam - OLAP).

Agricultural in terms of Sustainable Development of Agrarian Sector
Frýdlová, Monika ; Boháčková, Ivana (advisor) ; Smutka, Luboš (referee)
The sustainability discourse clearly gives priority to the so-called "three-pillar model", according to which sustainable development should equally try to reach ecological, economic, and social goals. An increasing variety of methods is being proposed to address the question of the measurement of sustainable development. The concept of sustainable development can be interpreted in many different ways, but at its core is an approach to development that looks to balance different, and often competing, needs against an awareness of the environmental, social and economic limitations we face as asociety. Submitting theses deal with measuring sustainable agriculture and introduces a practical methodology for evaluating the sustainability of agriculture system by means of composite indicators. This methodology was based on calculating seven sustainability indicators that cover the three components of the sustainability concept (economic, social and environmental). The methodological proposal implemented in theses allowed an integrated vision of agricultural sustainability and careful selection of sustainability indicators, carried out on the basis of reliability criteria and applicability. The evaluation of agricultural sustainability/production system sustainability using the methods suggested is a potentially useful tool for public decision-makers who are tasked with designing and implementing agricultural policy. The results demonstrated the usefulness of analyzing several sustainability indicators in conjunction, in order to obtain more robust results. Such information can help to improve current agricultural policies, such as income policy, agricultural structure policy and rural development policy, with the aim of improving the sustainability of the agricultural sector.
