Economic aspects use of energy of photovoltaic plant
Cerman, Marek ; Procházka, Jiří (referee) ; Macháček, Jan (advisor)
The major topic of this master‘s thesis is to create a complex model of general photovoltaic power plant (PVP). First chapters are engaged in research of photovoltaic. Growth of globally installed power and analysis of situation in Czech Republic are described in this section. The spectrum of conditions is introduced, from current legislative framework up to local Sun radiation. The actual technologies and their advantages are depicted, especially rate of utilization of energy. Expected trends of future development of conversion efficiency are mentioned, with prediction of production costs of photovoltaic. In context with those aspects, the question of grid parity achievement arises. The own assembled model of photovoltaic power plant has been created in Microsoft Excel. The mathematical apparatus is described in a separate chapter, individually solving technical part, which main result – the amount of yearly generated electricity, is applied for economical calculation. Final results are the usual economic indicators, mainly: Net Present Value (NPV), Internal Rate of Return (IRR), Levelized Cost of Electricity (LCOE). There is series of aspects defined by user in the model which may impact the amount of produced electricity and economics of user’s project, such as use of loan, replacement of converters, operational costs etc. These aspects are frequently neglected by project sellers. In the end, intended photovoltaic power plants of 2.75 kWp and 28.98 kWp are simulated by the model in real conditions of 2013. Sensitivity of impact of both proposals to the aspects mentioned above has been analyzed. In the conclusion the achieved results are summarized and the key factors which determine the PVP’s economic efficiency are assessed.

Representation of women in parliamentary political parties in the Czech Republic and in France since 2017
Součková, Alžběta ; Perottino, Michel (advisor) ; Guasti, Petra (referee)
This thesis focuses on parliamentary political parties in the Czech Republic and in France in the period since the 2017 legislative elections in both countries. It looks at the different attitudes and approaches of political parties towards women's representation. In addition to the historical context of the two countries and each political party, it also presents the long-term factors that influence the representation of women in political parties. Such factors include a country's political culture, the existence of women's party organizations, or the intra-party setting of quotas for women's representation. Institutional arrangements set from outside are also an important factor, with the parity law having impact on French political parties. The following analysis of different political environments attempts to capture these and other factors affecting women's representation and their practical manifestations. First, the party positions in the period under study are analyzed, followed by the candidate lists for the 2017 legislative elections and the results of these elections, i.e. the ratio of male and female occupancy of parliamentary seats and senior positions. Next, the elections to the upper chambers and women running for the office of the President of the Republic are approached. The...

Úhlové korelace v rozpadech Higgsova bosonu
Pleskot, Vojtěch ; Davídek, Tomáš (advisor) ; Dolejší, Jiří (referee)
The Standard Model predicts existence of one Higgs boson with combined parity CP = +1. In MSSM there exist Higgs boson with CP = −1 in addition. The work develops one method of Higgs boson CP determination on the basis of angular correlations of pions and ρ-mesons born in cascade decay H/A → τ− τ+ → ρ− /π− ντ ρ+ /π+ ¯ντ . The calculations are done in the leading order of perturbation theory. Further, the possibility of signal (Higgs boson decay) and background (Z boson decay) differentiation is studied. The processes in question are simulated using Monte Carlo generators Pythia and Tauola. Simulation outputs are compared with calculated theoretical results. 1

Úroveň reprodukčních ukazatelů prasnic v užitkovém chovu
Lujka, Jan
The aim of the final thesis was to perform analysis focused on the quality of reproduction parameters of the sows in the utility farming. The observation was focused on the influence of the sow on the reproduction yield and the losses of the piglets, it also observed the influence in the order of the litter and the losses of the piglets, following with the influence of the boar on the reproduction yield and the losses of the piglets and the influence of the boar on the birth weight of the piglets. During the analysis of the influence of the sow on reproduction parameters and the losses of the piglets, three types of sows were compared amongst which no statistically provable differences were found out. During the observation of the influence in the turning of the litter, a statistically provable difference ((P ≤ 0,05) was proved in the number of all the born piglets, that is among the sows in the first litter (14,31 pc/litter) and in the third litter (15,57 pc/litter). Also during the observation of the number of live born piglets in the litter between the sows in the first (13,39 pc/litter) and the second litter (14,47 pc/litter), as well as between the sows in the first (13,39 pc/litter) and the third litter (14,70 pc/litter). Another statistically provable difference (P ≤ 0,05) was noticed during the observation of the number of the weaned piglets between the sows in the first (12,13 pc/litter) and the fourth litter (12,69 pc/litter). During the observation of the piglets´ losses in pieces there was a statistically provable difference (P ≤ 0,05) between the sows in the first litter (1,26 pc/litter) and the third litter (1,71 pc/litter). During the observation of the influence of the boar on the reproduction yield and the losses of the piglets, three boars of various combinations were compared among which no statistically provable differences within the observed parameters were found. In the analysis focused on the influence of the boar on the birth weight of the piglets, the piglets taken after three boars, named A, B and C, were observed. During the evaluation a statistically provable difference was found out (P ≤ 0,05) among the average birth weight of the piglets by the boar A (1,33 kg) and the average birth weight of the piglets by the boar B (1,28 kg), and the average birth weight of the female piglets by the boar A (1,39 kg) and the average birth weight of the female piglets by the boar B (1,23 kg). Another statistically provable difference (P ≤ 0,05) was found out between the birth weight of the female piglets by the boar B (1,23 kg) and the birth weight of the female piglets by the boar C (1,42 kg). Between the values of the average birth weight of the piglets by the boar B (1,28 kg) and the average birth weight of the piglets by the boar C (1,45 kg) a statistically highly provable difference (P ≤ 0,01) was found out. Another statistically highly provable difference (P ≤ 0,01) was also found out between the birth weight of the female piglets by the boar B (1,23 kg) and the birth weight of the male piglets by the boar C (1,48 kg).

Fertility tables and application of the method in the analysis of regional differentiation of fertility in Spain
Ukolova, Elizaveta ; Šídlo, Luděk (advisor) ; Šťastná, Anna (referee)
The aim of the thesis is to construct period fertility tables according to Human Fertility Database methodology and different kinds of fertility indices, which are possible to derive from fertility table's functions. The method is then used when analysing regional differences in fertility behaviour among Spanish regions in 1981, 1991, 1999 and 2011. The study begins with a general overview of fertility trends in Spain. Then, the data part follows. Next, the methodology is discussed and some table's indices, which Human Fertility Database does not provide, are constructed. Following chapters focus on application of the method to real data. It was found out, that with the help of period fertility tables one can calculate not only the age and parity adjusted total fertility rate and the table mean age at birth, but also various transition probabilities between parity states and as well as other measures. All this could be done due to the possibility of deeper disaggregation of the table population. The main results obtained by applying the method brought several interesting findings. Most importantly, differences across regions in Spain have been disappearing over the years, but they still persist in some form, as regions with a higher fertility rate were concentrated in the southern part of the country in...

Representation of women in the French parliamentary elections in 2012 and 2017
Součková, Alžběta ; Perottino, Michel (advisor) ; Kubátová, Hana (referee)
This bachelor's thesis deals with a comparative analysis of the elections to the French National Assembly in 2012 and 2017 in terms of the representation of women among candidates and among elected deputies. The representation of women in the National Assembly is presented in the historical context of women in the political space from the French Revolution, through the gain of women's suffrage after World War II, to the Parity Act in 2000, which introduces legal quotas for women's representation in political institutions and functions. The thesis deals with factors that affects women's entry into politics and their number, such as the French Fifth Republic's electoral system in elections to the National Assembly or setting quotas for women's representation, as well as indicators that determine the real power and importance of women in politics. The comparison of the legislative elections in 2012, when the Socialist Party won, and the legislative elections in 2017, when the new political group En Marche won the majority, deals mainly with different approches of political parties to the law of parity and gender equality and then also with differences in filling key positions in the National Assembly. The conclusion of the thesis presents the results of the analysis, which will either confirm or...

Biting midges and their patogens
Mračková, Marie ; Votýpka, Jan (advisor) ; Modrý, David (referee)
This thesis deals with biting midges of the genus Culicoides, which are tiny nematoceran insects belonging to the Diptera, and their parasites. Biting midges partake in transmissions of several parasitical organisms of various groups. Most notably, they are the vectors of several pathogenic viruses which might have a serious impact on livestock. However, the thesis deals with detection of parasites belonging to Trypanosomatids and Filarioids related to two independent biting midges collections - from the Czech Republic and from the Central African region. Apart from testing biting midges, there were carried out the tests on the occurrence of the same group of parasites within ruminant hoofed games in the Czech Republic. Our goal was to find out whether the same parasites occur with biting midges and their hosts (hoofed games) and whether biting midges could play a role as vectors. Biting midges are relatively overlooked group of haematophagous insects. Until recently, they had not been paid much attention, which changed with the spread of Bluetongue virus over Europe. This stimulated a widespread monitoring of biting midges in several European countries, including the Czech Republic. This helped to gain a large amount of data about the occurrence of biting midges near livestock. Nevertheless, there is no...
