Molecular biology and ecology of microbial decomposition of plant-derived biopolymers in forest ecosystems
Žifčáková, Lucia ; Baldrian, Petr (advisor) ; Uhlík, Ondřej (referee) ; Bárta, Jiří (referee)
The abilities of fungi and bacteria to degrade simple and complex carbon compounds derived from different sources, such as root exudates, litter, soil organic matter or fungal mycelium were studied in this dissertation. Knowledge of functional traits, especially degradation abilities of fungi and bacteria, are important for deciphering the black box of microbial functioning in topsoil and thus aiding in modeling and predicting future directions of microbial communities development in face of global changes. Among fungal cultures form culture collection representing strains with different taxonomy and ecophysiology, the ecophysiology of fungi was more important in manifestation of functional traits than taxonomy. Among bacterial isolates from the litter and soil of spruce forest, Acidobacteria were confirmed to express multiple decomposition enzymes in high rates in vitro and were also abundant and active degraders in acidic spruce forest soil. The expression of degradation capacities of both bacteria and fungi were further studied in situ in spruce forest topsoil, that represents an important environment due to the ubiquity of coniferous forests on the Northern hemisphere. There is an obvious gap of knowledge, when comes to our understanding of seasonal effect on microbial functioning, and this is...
Parallelisation of Ultrasound Simulations on Multi-GPU Clusters
Dujíček, Aleš ; Kula, Michal (referee) ; Jaroš, Jiří (advisor)
This work is part of the k-Wave project, which is a toolbox designed for time ultrasound simulations in complex and heterogeneous media. The simulation functions are based on the k-space pseudospectral method. The goal of this work is to compute these simulations on graphics cards using local domain decompostion. Thanks to decomposition we could compute these simulations faster, and on larger data grids. The main goal of this work is to achieve efficiency and scalability.
Odhad disparit v zacházení s cizizími statními příslušníky v trestním procesu v České Republice
Vávra, Jan ; Dušek, Libor (advisor) ; Kovanda, Lukáš (referee)
This thesis examines the effect of foreign nationality on the outcomes of criminal process in the Czech Republic. Foreign citizens are overrepresented by 2% compared to their share in population in all stages of the criminal process, suggesting possible discrimination by domestic authorities. Using rich case level datasets from 2005 to 2015 observed gaps are decomposed to part explained by a difference in the objective characteristics of the cases and unexplained part, suggesting possible inequality of treatment. Foreigner gaps in probability of charge, probability of conviction, probability of imprisonment, length of the sentence and probability of release from prison on parole are decomposed. Majority of observed disparities in the outcomes can be attributed to higher involvement of foreigners in more serious crimes compared to nationals. Unexplained disparities remain in probability of imprisonment and probability of release on parole, suggesting possible unequal treatment in these two outcomes.
Co3O4 Supported on Different Supports for N2O Decomposition.
Klyushina, A. ; Pacultová, K. ; Jirátová, Květa ; Obalová, L.
In this work Co3O4 catalysts supported on different kind of shaped supports (rings, quadrulobes) were prepared by incipient wetness impregnation method. As support materials commercial supports made of MgAl oxides, Al2O3 and TiO2 were used. The catalysts were characterized by AAS, XRD, Raman, FTIR, SEM, H2-TPR and nitrogen adsorption methods and tested for nitrous oxide decomposition.

Nguyen, Anh Khoa ; Novotná, Veronika (referee) ; Kropáč, Jiří (advisor)
This bachelor thesis is focused on analysis of indicators in e-commerce Sportobchod.cz with the time series method. The thesis is divided into parts, where the first part contains the theory associated with time series and the second part contains an analysis of real data, results, solutions suggestion and assessment of possible prognosis.
Creating Internal Database by Using SQL Server
Košinová, Kateřina ; Marek, Tom (referee) ; Kříž, Jiří (advisor)
This thesis focuses on the design and creation of internal SQL database to improve the operation of company Service Baur, s. r. o. In the first part of this work are defined the oretical foundations that are necessary for designing internal database. The second part analyzes the current state the company and the third part focuses on the design solutions and service benefits for company Servis Baur, s. r. o.
Productivity Analysis of Králík's Bakery Using Time Series
Šimková, Marcela ; Pokorný, Petr (referee) ; Kropáč, Jiří (advisor)
The purpose of this Bachelor thesis is to come up with an in-depth efficiency analysis of Kralik's bakery by means of using time series. The intput data set is entirely based on references which were obtained directly from the bakery. Main intention is therefore concentrated on drawing up an analysis that will be used for prediction of production factors in a future. This will consequently lead to better optimization of production plans.
Statistic evaluation of chosen investment funds
Mitrengová, Anna ; Odehnalová, Bohumila (referee) ; Kropáč, Jiří (advisor)
It exists a lot of ways, how to value our money. One of them is its investing to investment funds. But nowadays it is difficult for us to choose in such a big supply of the funds. That is why a lot of investors ask their financial advisors who are able to help them with the choice Everyone who is interested in coffers investing would surely appreciate some well arranged investment fund comparison which would help him/her in quick decision to which of these funds entrust the money for a time. By this bachelor thesis I try to create right such summary. I hope I will help to make the whole investment procedure effective beginning with the choice of the right investment fund.
Static image enhancement using wavelet transform
Candrák, Matúš ; Rajmic, Pavel (referee) ; Smékal, Zdeněk (advisor)
In tomography and ultrasound signal processing, there is the noise build-up into the processing. Bachelor's thesis deals with static images highlighting, with denoising using wavelet transformation and edge detection with basic operators. This work describes some types of wavelts used for denoising of image and basic operators for edge detection in the image. The last part deals with a particular application for image processing, which was created in MATLAB.
