Global Economic Outlook - February 2017
Česká národní banka
The February issue of Global Economic Outlook presents the regular monthly overview of recent and expected developments in selected territories, focusing on key economic variables: inflation, GDP growth, leading indicators, interest rates, exchange rates and commodity prices. In this issue, we tend to explore analytically the effect of (un)conventional monetary policy measures on shadow interest rates in the euro area and the USA. Based on our estimates, we show in this article that the effect of monetary policy measures on shadow rates differs depending on whether they were aimed at stabilising financial markets or further easing monetary conditions. We also indicate how the effects of measures taken by central banks can change depending on the current level of financial stress.

Calculations of nanocrystalline diamond-covered waveguides based on amorphous silicon
Jirásek, Vít ; Prajzler, Václav ; Remeš, Zdeněk
Nanocrystalline diamond (NCD) coatings on planar waveguides (WG) in the IR region allow to design optical sensors sensitive to absorbers like proteins or other biomolecules. In this contribution, we present a 2D model of a multi-layer WG developed under FEM (finite element method) simulation software Comsol Multiphysics. The model is based on the modified wave equation solved in the frequency domain and includes optical absorption. It was found that for the single-mode WG working in the narrow region of 1550-2000 nm the silicon thickness must be 150-320 nm. It was found that in order to keep a reasonable signal attenuation, the NCD film must be prepared with the optical absorption coefficient lower than 10 cm-1, being a rather challenging task. Dependencies of the signal attenuation on the NCD film thickness, absorbing layer height, its absorption coefficient and exciting wavelengths are presented.\n

The Fruit Beers Popularity in the Czech Republic
Balaštík, Milan ; Maier, Tomáš (advisor) ; Lukáš, Lukáš (referee)
The main topic of this thesis is the popularity of fruit beers in the Czech Republic. It describes a generic distribution of fruit beers, both abroad and in our country. Shows an overview of large and small manufacturers in this category in the domestic market. It focuses on the current situation flavored beer on domestic and foreign markets, according to the latest data. Based on the survey are analyzed consumer preferences in the domestic market. They are then formulated breweries general recommendations arising from the outcomes of the survey. Subsequently, using basic statistical methods detected significant correlation between the consumption of flavored beers and gender and between consumption and age of respondents. If so, then it determines the strength of this dependence. It was found that while significant correlation was demonstrated in sex exists between consumption and age of the respondents. The strength of this dependence was assessed as moderate. It was finally drafted forecast consumption of mixed drinks based on beer in the Czech Republic. The analyzed time series contained the actual annual data maintained by the Czech Beer and Malt Association from 2012 to 2015. The forecast was calculated for the next two years. It was found that consumption of mixed drinks based on beer in the future will continue to decline.

Statistical analysis of resocialization care after prison release
Dlouhá, Šárka ; Hlavsa, Tomáš (advisor) ; Michal, Michal (referee)
The level of crime has to be regulated in order to prevent the crime to cause major damage to society. Therefore it is profitable to address criminal recidivism as well. Recidivism is caused by a complicated process of reintegration of people with criminal records back to society. The main goal of this thesis was to find the main factors affecting reintegration process of people after incarceration. The thesis is trying to reach the results by quantitative research, specifically examining the frequencies and dependence of categorical variables. The main factors which influence the reintegration process of people with criminal past are unemployment and indebtedness. These elements are affected by certain demographic factors. These factors also influence the type of criminal activity and the probability of criminal recidivism.

Improving Services for End Users Using System Center
Toman, Martin ; Havránek, Martin (advisor) ; Ladislav, Ladislav (referee)
The weakest part of the process of preparing the new computer for users in the company Linet is long and hard installation of the operating system using tool Clonezilla, and then manual installation of required software. In addition, if the software update comes out, it needs to be installed on all computers manually. It is therefore necessary to find better and automated way of installing updates and preparing computers for users who will get the device earlier, software will be always up-to-date and IT staff will have extra time to solve other tasks.
The company uses only the Windows operating systems from Microsoft, therefore was chosen a tool from the same company: Microsoft System Center Configuration Manager. For testing was used virtual environment Hyper-V, in which there were created two servers: one for a functioning domain infrastructure and the other for tool Microsoft System Center Configuration Manager. Functionality was tested on Virtual stations Client#. After verifying the functionality of the tool it will be deployed into infrastructure of the company Linet.

Vliv odvodnění a vegetace na množství a diverzitu metanogenů v rašeliništích
LÍSALOVÁ, Olga
This work deals with attribute of microbial communities, especially methanogenic Archaea in pristine and drained peatlands. Methanogens are strictly anaerobic microorganism thus they live in deeper anoxic layers of peatlands. Therefore, the aim of this study was to determine how the drainage affects the amount and diversity of methanogens depending on different depths, types of peatlands and litter type.

Is import of goods from european countries to Czech republic more or less influenced by changes in nominal and real exchange rates than in non european countries?
Vereš, Jan ; Stroukal, Dominik (advisor) ; Slaný, Martin (referee)
This bachelor thesis analyses the connection between import of goods from foreign countries to Czech Republic and the exchange rate changes. The initial hypothesis of this paper is to prove that the depreciation of domestic currency has positive influence on balance of trade balance. For this purpose there is eight econometric models which were created by using time series from years 2003 to 2016. These models are divided in pairs among four chosen countries. For each country two models were created that follow the development of trade balance between Czech Republic and one of the countries in two different time frames. All the models always use the real effective exchange rate, growth rate of GDP for Czech Republic and growth rate of GDP for one of the countries as explanatory variable. It is connected with the second task of this thesis, which is the analysis of the differences in the behaviour of the models that belong to the countries which are members of the EU and these that are not. The aim is to find out whether the existence of tariffs on imported goods from countries out of the EU causes visible differences in the behaviour of the variables that were included in the models. Based on the outcomes of all eight models the main hypothesis has been proved right for three out of four countries. In the models for Germany, China and France the relation of real exchange rate and trade balance came out as positive in long term, in short term the outcome was ambiguous. The second question of this thesis has been answered, but its added value is questionable. The final models for each state do show some noticeable differences and they can be used to determine if the influence of the change of exchange rates on trade balance is smaller or bigger in the countries where tariffs are used. On the other hand, from the results we can learn that the sample of only four countries is insufficient for the deduction of any conclusions.

Běťák, Petr ; Sládek,, Petr (referee) ; Bartoň,, Zdeněk (referee) ; Musil, Vladislav (advisor)
The thesis introduces new semiconductor structures that are used as protections against Electrostatic Discharge occuring in integrated circuits. The fundamental structure for modeling and simulation has been lateral Silicon Controlled Rectifier. This SCR structure has been modificated to enable tuning of the triggering and holding voltages by changing geometrical mask dimensions. On the base of modeling and simulation the new proposed structures have been published. Also several protection structures have been designed to be manufactured and measured on a testchip. The final electrical behavior has been verified by measurement. Finally, the focus has been aided to protection circuit with bipolar transistor. This approach has been also simulated and verified by measurement. Advantages and disadvantages of the proposed protection structures are commented in the thesis.
