Oxidation of Volatile Organic Compounds in a Multifunctional High Temperature and High-Pressure Cassette Microreactor
Vajglová, Zuzana ; Stavárek, Petr ; Křišťál, Jiří ; Jirátová, Květa ; Ludvíková, Jana ; Jiřičný, Vladimír
Analysis of the total oxidation of ethanol including reaction intermediates data obtained in the examined reactors on the temperature showed that differentmaterial applied in the construction of reactors and their arrangement give slightly different results of catalyst testing, the ones obtained from microreactor being more precise. More precise control of reaction temperature due to higher heat transfer capabilities and limited backmixing of reaction mixture in a packed bed microreactor is advantageous and leads to the more accurate results of oxidation catalysts testing. However, it is necessary to ensure in order the material used for the reactor construction did not affect the catalytic reaction. The results accomplished confirm that microreactors are not only suitable for performing of catalytic reactions in a laboratory scale but also promising way for creation of new, safer and cleaner production processes.

Výběr a implementace open source nástroje pro řízení portfolia projektů
Marek, Jan ; Chlapek, Dušan (advisor) ; Kučera, Jan (referee)
Methods and ways of implementation of changes and innovations in companies through project management are in today's society very well established. There exists methodologies, techniques and tools for the management of individual projects. However in a role of project manager, I very often faced the fact that companies are performing the project portfolio management in very intuitive way. This in itself leads to failed and prematurely terminated projects, initiation of the wrong projects or realisation of correct projects, but at the wrong time. Very often I have also recognized, that there is lack of awareness of fact, that there are also Open Source applications that can help with the organization's portfolio. This thesis deals with the definition of requirements, search and selection of proper OSS application and subsequent implementation. In the first part of this thesis I prepare a theoretical framework about PPM, and on that basis then identify and verify a set of requirements for selection of right OSS PPM application. The next section of thesis describes searching for suitable applications from a variety of sources, assessment against the requirements and the final selection. In the last part the implementation project is drafted, which aims to serve other colleagues in project management as one of the possible implementation paths. The outputs are then continuously confronted with experts in matter of projects and project management in the field of IT in order to maximize symbiosis between theory and real life experiences. Virtually every project management methodology defines the collection of already-proven techniques, best practices or lessons learned from the previous similar implementations. The main contribution of this thesis I see in fact that it contains not only the design of the project implementation, but also describes a logical path, what leads to the result. Therefore this thesis could be used as a base or discussed best practice, when a project of implementation of PPM application in place.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.

Common features of movies integrating the theater phenomenon into their narrative and stylistic structure
Merková, Hana ; JAŘAB, David (advisor) ; Havas, David (referee)
The subject of this bachelor thesis is the common features of foreign and czech movies integrating theater phenomenon into their narrative and stylistic structure. For better explanation, firstly, the forms, which are not included in the area of interest are described- the audiovisual record of theater performance, film adaptation of dramatic play, or insertion of theater performance into the movie content. In following chapters, three different movie examples working with theater in their structure are being described and analysed. Then, thesis is trying to find the reasoning for the usage of two different mediums and their mutual comunication as a principle of autorship. Finally, thesis is trying to summarize common thematic and formal characteristics of chosen movies.

Global Economy Outlook - December 2016
Česká národní banka
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 also focus on a major phenomenon of the day: the migration of people into Europe, and Germany in particular. In this context, we present an analysis of the effect of the increased number of refugees on the German labour market. We show, among other things, that the incoming migrants will be far from enough to cover the demand for labour in Germany and also that they will compete more with workers arriving in search of jobs in Germany from Central and Eastern European countries than with German citizens.

Global Economy Outlook - November 2016
Česká národní banka
The November 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 also focus on the relationship between the Brent crude oil price and the US dollar exchange rate over the last ten years. The results show that the inverse relationship between the Brent price and the nominal effective exchange rate of the dollar still applies, helping dampen fluctuations in the dollar price of oil in “non-dollar” economies.

Bystander effect from paramedic point of view
TOMAN, Antonín
This bachelor thesis named "bystander effect from paramedic point of view" is focused on professional rescue workers view on the presence of bystanders by an individual, occurring in an emergent situation. Similarly, this work takes into consideration the problems of influence that bystanders have on the professional activities of paramedics. Onlookers watching the accident are an integral part of the daily activities by rescue workers, equally as bystander effect individuals. The work is divided into theoretical and practical part. The first chapter of the theoretical part deals with the history of emergency medical services and its function, medical operations centre of first aid function and legislation, the second chapter introduces the problems of communication in the pre-hospital emergency care, along with issues relating to stressful situations in the pre-hospital emergency care. The third chapter deals with the issue of prosocial behaviour. It discusses the factors that affect the ability to provide first aid, and it also deals with the problems of prosocial behaviour by individuals and dilemmas, which according to the literature affect each individual, who occurs in the situation when he must provide help to someone else. i also discuss norms of social behaviour. Chapter also takes into account the problems of social boundaries that lead individual behaviour to the benefit of society. a different view of single individuals on social norms is also taken into consideration. In the fourth chapter of the theoretical there is provided a comprehensive insight into the psychological phenomenon, that was first described in the USA. Dispersal of responsibility is a basic prerequisite for the origin of bystander effect. Dispersal of responsibility arises from the large number of individuals at one place, among which is the responsibility equally divided and does not lie to anyone truly full weight of responsibility for the situation. Another aspect is pluralistic ignorance, which arises from the assumption, that people do, that nothing is happening and act absently. An integral part of the bystander effect is an inhibitory influence of audiences, when is the individual, thinking about the help, paralyzed by the presence of bystanding witnesses. i also discuss personality factors and the willingness of individuals to help. The aim is to map the experience of paramedics, whose work is during intervention influenced by dilettante bystanders, and map the awareness of paramedics on bystander effect. There were selected two research questions. The first one determines whether bystanders lay persons affect paramedic work and the second one examines what kind of information about bystander effect paramedics have. To achieve these objectives, the practical part uses a qualitative research strategy. Data collection was accomplished using a semi-structured interview. The interview was compiled from pre-prepared questions focused on the impact of bystanders dilettantes in the work of medical paramedics and also on awareness about the bystander effect. The sample consisted of 8 paramedics with at least five years of experience in the medical rescue service. Data recording was realized using audio recordings, while transcription evidence was subsequently obtained. Evaluation of the data was carried out in the form of content analysis of transcribed interviews. Except the issue of bystander effect there was also discussed real case interpretation of this problem. The research showed that lay bystanders affect the work of paramedics. It was also found out, that rescuers do not have general awareness of the bystander effect. Results and personal statements of the respondents in the research generally agree with the opinions released by the literature. After any adjustment this bachelor thesis it could be used as educational material.
