Signal processing and receiving in UMTS system
Hron, Michal ; Hanus, Stanislav (referee) ; Kejík, Petr (advisor)
This semestral thesis be concerned with datailed analysis of receiving and processing signals in UMTS network system. Insistence of this work is setting to principals of RAKE receiver and processing signals in CDMA networks downlink channel. Through development system MATLAB simulates real function of RAKE receiver. This project is giving fundamental knowledges about receiving and processing of multipath signals to readers.

A Draft of a Corporate Financial Plan
Hron, Michal ; Ludvíková, Lenka (referee) ; Karas, Michal (advisor)
Master’s thesis is focused on draft of a corporate financial plan for agricultural cooperative Sněžné. Financial plan is created for period 2020 to 2023. In the first part, a literary research is performed theoretical knowledge related to financial planning, financial and strategic analysis. In the next part, the agricultural cooperative is introduced and analyzed on the basis of individual methods of strategic and financial analysis. The summary of these analyzes is performed by SWOT analysis. In the last part of this master‘s thesis, a financial plan is created in an optimistic and pessimistic variant with 4 years outlook. In the end, the financial plan is one more analyzed and assessmented.

Experimentální studium centrální a okrajové oblasti prstence plazmatu na tokamaku Compass
Štefániková, Estera ; Tichý, Milan (advisor) ; Hron, Martin (referee)
High-resolution Thomson scattering system on the COMPASS tokamak provides electron temperature and density profiles in the central and edge plasma region. The spatial resolution in the edge plasma region is optimized for edge transport barrier studies. Formation of characteristic edge profiles (pedestals) is observed during high-confinement mode, i.e. the core electron temperature and density are raised up by the value of pedestal height. Both the electron and density pedestals are well-fitted by a modified hyperbolic tangent (mtanh) function, a five parameter model giving important parameters such as pedestal height and width, necessary for further analysis of the physics behind the transport barrier formation. A fitting technique of the full radial profiles of electron temperature, density and pressure during H-mode is also described. Using the fitting, electron temperature and density on top of pedestal are statistically processed to find a possible threshold for various H-mode regimes.

Unconditional basic income as a solution to unemployment
Hron, Matouš ; Mazák, Jaromír (advisor) ; Vlček, Josef (referee)
In this bachelor thesis I seek an answer to a question whether universal basic income can serve as a solution to mass unemployment. I use theories that explain the causes of reduced well-being of the unemployed. According to restricted agency model, the reduced well-being can be explained by material deprivation. Latent deprivation model seeks the answer in non-material needs that are not fulfilled in unemployment. In the first part of the thesis, I make use of empirical studies of unemployment, whereas in the second part I seek the answer by analyzing European Social Survey data from Czech Republic using multiple linear regression method. In case of evidence supporting the restricted agency model, universal basic income might be a viable solution to unemployment. The results show mixed evidence for both models.

Fluctuations in the scrape-off layer and edge plasma of the COMPASS tokamak
Seidl, Jakub ; Jiráková, Kateřina ; Adámek, Jiří ; Grover, Ondřej ; Horáček, Jan ; Hron, Martin ; Vondráček, Petr
We have identified two distinct types of turbulent fluctuations in COMPASS plasmas, the high-frequency edge oscillations and low-frequency SOL blobs. The transition region is localized in the near SOL, where both types spatially overlap and interact and the radial particle transport gradually transfers from high to low frequencies. Even though skewness of isat fluctuations is positive even inside LCFS, distinguishable Gamma-distributed PDF, formed by the low-frequency fluctuations, arises in the near SOL. This supports, together with turbulence spreading rate being positive in the near SOL but negative in the edge, the picture presented in [3] that most of the fluctuations that form a positive skewness in the edge region disappear around LCFS and new blobs are formed in the near SOL. Further, we cannot confirm the assumption that the blobs are generated randomly according to a Poisson process. Oscillations of all measured quantities, incl. radial particle flux, in the near SOL are peaked around ∼13 kHz. This seems to correspond to a poloidally rotating structure with a rather large poloidal wave-length ∼ 15 − 20 cm, that at least partly modulates blob generation. Nevertheless, we note that time separation of blobs becomes more random further in the SOL, possibly due to differences in their individual propagation. These observations hold for diverted plasmas, but the situation may be different in limited low-elongation plasmas where the radius of zero skewness was observed to be shifted significantly (several cm) inwards, compared to diverted configuration, and Gamma-like PDF is detected even inside the LCFS. Study of these plasmas is ongoing.

Fluctuations in the scrape-off layer and edge plasma of the COMPASS tokamak
Seidl, Jakub ; Jiráková, Kateřina ; Adámek, Jiří ; Grover, Ondřej ; Horáček, Jan ; Hron, Martin ; Vondráček, Petr
In this work we study properties of turbulent structures in the scrape-off layer (SOL) and edge plasma of the COMPASS tokamak. Two distinct types of coherent oscillations are observed: a) broadband high frequency branch rotating in the electron diamagnetic direction, appearing mainly in the confined region but protruding also to the SOL b) low-frequency blobs rotating in an opposite poloidal direction, formed in the vicinity of the radius of zero electric field. The transition region is localized in the near SOL, where both types spatially overlap and interact and the radial particle transport gradually transfers from high to low frequencies. Even though skewness of fluctuations of the ion saturation current is positive even inside LCFS, distinguishable Gamma-distributed PDF, formed by the low-frequency fluctuations, arises in the near SOL and most of the fluctuations that form a positive skewness in the edge region disappear around LCFS.
