Factors affecting the price of real estate in the selected area
Olbrechtová, Zuzana ; Němcová, Lenka (referee) ; Tichá, Alena (advisor)
This thesis is focused on the factors affecting the price of real estate within the market valuation, specifically those which affect the market value of a building plots, family houses and housing units. There aren´t any publications with a comprehensive description of these factors currently. The main aim of this thesis is to define the main factors including their description and an influence on the price of real estate. Factors are divided into inner and outer factors and further into particular categories. Based on this division the analysis of the influence of the groups, categories and factors is carried out within selected types of real estate which is backed up by real examples of market valuations. Further on, the map of a preference of localities in the district Opava is worked out of the outer group of factors. There is also obvious the price level of real estate in this district which can serve as a valued basis for municipalities within urban and other planning. The result of the analysis of influence of the factors is the conclusion that on setting the market value of a real estate outweighs the group of outer factors, or else the influence of a locality in which is a real estate situated is outweighing over the particular real estate.

Study of electrolyte influence on diaphragm discharge stability and efficiency
Němcová, Lucie ; Krčma, František (referee) ; Kozáková, Zdenka (advisor)
This thesis is focused on so-called diaphragm discharge, which is one kind of electric discharges in liquid, which belongs among so-called AOP´s techniques, still more used for water cleaning in the present. One of effectiveness and stability indicators of diaphragm discharge is generation of hydrogen peroxide. In theoretical part, detail principle description of electric discharge in liquid is situated. Further, properties of electrolyte are introduced and general spectrophotometric method of obtained sample determination is described. In experimental part, a full procedure of experiment is introduced. Next part containing results and discussions introduces particular results of individual measurements and their reasons. Final chapter is the end, which forms total summary and evaluation of all results. By the application of all chosen electrolytes in solution at diaphragm discharge formation of hydrogen peroxide has appeared. Inorganic and organic electrolytes were used. As inorganic electrolytes following salts were selected – solutions of halogenides, next sodium nitrate as a representative of nitrates, potassium dihydrogenphosphate as a representative of phosphates, etc. Representative of organic electrolytes was citric acid. The value of initial conductivity of electrolytes had the main influence on hydrogen peroxide formation. Electrolytes potassium dihydrogenphosphate and sodium sulphate the great influence on effectiveness and stability of the diaphragm discharge. Their rate constants reached maximum value by the application of solution with initial conductivity of approximately 400 mikrosiemens, particularly 0.0492 mmol/l.min and 0.048 mmol/l.min. On the contrary, low values of rate constant were achieved in electrolyte ammonium chloride at around the same initial conductivity – 0.0269 mmol/l.min. During experiments stainless steel and platinum electrodes were used. It was found that kind of electrode material hadn’t influence on generation of hydrogen peroxide. Hydrogen peroxide was formed only in the cathode space.

Optimization Models in Energy Production
Němcová, Lucie ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This bachelor's thesis focuses on optimization of a boiler's size of a waste incineration plant from an economic point of view. The problem was approximated by discretization because random parameters with normal distribution occured in the incineration plant model. To evaluate the quality of such approximation there were created confidence intervals using random sample information, independent random number streams method and common random number streams method. Used methods were compared and the smallest number of scenarios that aproximates the problem "well enough" was proposed in the last part of this thesis.

Study of Plasma - Liquid Interactions
Němcová, Lucie ; Brablec, Antonín (referee) ; Obradovic, Bratislav (referee) ; Krčma, František (advisor)
Disertační práce se zabývá detailním studiem vlastností různých elektrických výbojů generovaných ve vodných roztocích. Tyto výboje se staly v posledním desetiletí velmi populárním tématem, a to zejména díky mnoha praktickým využitím jako například v biomedicíně, čištění odpadních vod, ekologii nebo nanoinženýrství. Studium je zaměřeno na generaci peroxidu vodíku, jakožto jednu z nejvýznamnějších částic generovaných právě elektrickými výboji v kapalinách. Pro první část této práce byla využita speciální výbojová komora zkonstruovaná na Fakultě chemické Vysokého Učení Technického v Brně. Komora byla rozdělena tenkou diafragmovou přepážkou na dvě poloviny, přičemž uvnitř přepážky se nacházela malá dírka. V každé části komory se nacházela jedna elektroda, a obě dvě části komory byly vyplněny kapalinou. Ze zdroje bylo do kapaliny aplikováno vysokofrekvenční napětí (1 a 2 kHz), které tak vlastně upravovalo roztok chloridu sodného (1.5 l). Bylo zjištěno, že tento druh napětí, v porovnání s DC, nezpůsobuje nežádoucí přehřívání roztoku (počáteční vodivost 100 - 800 S/cm) během jeho úpravy při zachování účinnosti produkce peroxidu. Experimentální aparatura pro druhou část práce byla sestavena na Gentské Univerzitě v Belgii. Stejnosměrný výboj byl generován v bublinách plynů (He, Ar, N2, vzduch) v prostředí vodných roztoků. Byla studována generace peroxidu vodíku a odbourávání organických barviv přítomných ve zkoumaném roztoku. Ke generaci peroxidu vodíku byl použit roztok NaH2PO4 . 2H2O (5 microS/cm, V= 750 ml), ke zkoumání rozkladu barviv byly použity roztoky organických barviv Direct Red 79 (20 mg/l) a Direct Blue 106 (20 mg/l, V= 750 ml). Minimální koncentrace peroxidu vodíku byla naměřena při aplikaci proudu 10 mA, zatímco maximální koncentrace peroxidu vodíku byla zaznamenána při použití proudu 30 mA. Rozklad organických barviv vykazoval stejné vlastnosti. Čím vyšší byla dodávaná energie, tím více barviva se odbouralo. Třetí část práce probíhala ve spolupráci s Queen's University of Belfast, Centrum for Plasma Physics, UK. K realizaci experimentů bylo využito vysokofrekvenčního plazmového skalpelu (Arthrocar). Bylo zjištěno, že hodnota koncentrace peroxidu vodíku dosahovala maxima v roztocích s nepatrným přídavkem alkoholu (0.25 %). Celkem byly studovány čtyři 0.15 M roztoky BaCl2, Na2CO3, KCl a NaCl (V= 20 ml), jejichž počáteční vodivost se pohybovala kolem 13 mS/cm. Z výsledků bylo patrné, že největší rozdíl hodnot pH byl zaznamenán u roztoků s přídavkem ethanolu. V optických emisních spektrech byly identifikovány především radikály OH, které jsou prekurzory peroxidu vodíku. Výsledky ukázaly, že plazma v takovémto roztoku je stále tvořeno, což může být považováno za první krok generace plazmatu v organických sloučeninách. Poslední část práce byla zaměřena na tzv. mikroplazmatický jet v přímém kontaktu s kapalnou fází. Tato experimentální práce byla realizována na pracovišti Nanotechnology & Integrated Bio-Engineering Centre (NIBEC), University of Ulster, UK během studijní stáže. Jako vodivé médium byl použit roztok trihydrátu kyseliny chlorozlatité s různou počáteční vodivostí. Zajímavým zjištěním je fakt, že při tomto druhu měření bylo generováno stabilní plazma i při velmi malém výbojovém proudu (0.05 a 0.2 mA), a tedy i peroxid vodíku vznikal při velmi malé vstupní energii, což může být považováno za velmi dobrý výsledek.

Market value and cost price of real estate
Olbrechtová, Zuzana ; Němcová, Lenka (referee) ; Tichá, Alena (advisor)
This thesis is focusing on market value and cost price of a real estate. The difference between the above-mentioned market value and cost price in relation to a specific real estate is emphasized. To regard and evaluate this difference a database of real estates was needed to be established. Building plots in the region of Opava with a planned construction of a detached house were chosen to establish this database. In all cases, the cost price of the structure and the future market value of the building plot with a completed building of the detached house was known. Based on the database, the main impact of each characteristic of the structure and the building plot on the difference in market value and cost price of particular real estates is evaluated in the main part of this thesis. In it’s last part this thesis comes to the application of ascertained conclusions on the problematic of municipalities management with municipal real estates in the most economical effective way.

Coolness and subcultural capital in the contemporary Prague alternative techno scene
Caha, Vilém ; Císař, Ondřej (advisor) ; Němcová, Lucie (referee)
The subject of this thesis is a qualitative sociological study that examines the contemporary Prague alternative club and rave scene as a subculture. The aim of the study is to find out how members of the subculture perceive and reflect on their subcultural identity. The theoretical part discusses several theoretical concepts related to this topic. The process by which nine informants were recruited and their interviews used as the primary source of data is described in the methodology chapter. Data for the research was collected using qualitative methods, i.e. semi-structured interviews, which were then analysed using open coding. The results suggest that several aspects influence the subcultural identity of techies - engagement in the scene and sharing of ideology are the main ones. The study could contribute to a deeper understanding of the contemporary Prague alternative techno scene and how its members shape their subcultural identity.

Framing the Cyprus Conflict in the Czech Media
Němcová, Linda ; Nečas, Vlastimil (advisor) ; Křeček, Jan (referee)
This diploma thesis focuses on the framing of the Cyprus conflict in Czech print newspapers from the perspective of peace journalism. The aim of this thesis is to examine the journalistic tendencies that are applied in the selection and processing of events related to the Cyprus conflict in the Czech media. Not only the main topics that are preferred by the media in their coverage in this context are monitored, but also the way in which the various actors in the conflict are presented and the ratio of representation of official and unofficial sources of quotations. The theoretical part of this thesis explains the concept of framing, its relation to media agenda setting theory, the framing process and the typology of frames. It also introduces the concept of peace journalism in contrast to war journalism. At the same time, this chapter offers an overview of the origins and development of the Cyprus conflict up to its current form. The last subchapter of this section is devoted to selected foreign research on framing the Cyprus conflict, especially its findings and sets of frames. These are used in a quantitative content analysis focusing on the occurrence of these predefined frames in Czech print newspapers. In the interpretation of the results, the correspondences or differences with these studies are...

Modelling of the waste flow in the Czech Republic
Němcová, Lucie ; Procházka, Vít (referee) ; Šomplák, Radovan (advisor)
Strategic planning is the basis for efficient and sustainable waste management. Data collection and its deep understanding are essential for effective planning. Waste flows are an important information to assess waste management to date. This information has so far been available only aggregated at national level in the Czech Republic. In this thesis, an approach has been developed to reconstruct the waste flows at a sub-national level from available data. The approach consists of two optimization models: partial and final. The partial model is based on expert assumptions. The reconstruction of the flows by the partial model is done sequentially in smaller groups of flows. The computation of the partial model is repeated with different composition of the groups of flows optimized at the same time. Each iteration results in a~candidate solution which is used as an input data for the final model. The solution of the final model yields the final reconstruction of the waste flows. Model development and testing was carried out on problems simulated based on the real data from the waste management of the Czech Republic.
