Kajzar, Vlastimil ; Waclawik, Petr ; Staš, Lubomír
In the northern area of mining areas Doubrava and Karvina mines on the border RA Detmarovice and Doubrava are implemented, the mining activities. For this reason, in order to detect possible effects of the mine to the surface and surface objects twice a year height focuses, points in this area stable. From 2014 he was a contractor for these works chosen by the Institute of Geonics, v.v.i., Ostrava. In August and November 2016 survey conducted campaigns planned this year, during which it conducted a total of 4 highrise focus of inter-related leveling routes, which are formed by these points. Highrise points are stabilized in the area of interest in several ways - usually in steel design height marks on buildings, then as an iron bolt concreted in the ground or using nails driven into the concrete foundation or other alternative means. Distribution points in the area of interest is indicative captured in the map appendix. Existing trace and focus points are highlighted in green, yellow trace inaccessible points, refocused points in red and violet points that have occurred to their long term disablement or destruction. Each zaměřovaných points in order to trace the terrain carefully documented (GPS coordinates, photos, text description) and registered. These documents are available from the contractor.

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.

Contemporary art after Late Photography.
Czanderle, Michal ; DVOŘÁK, Tomáš (advisor) ; JANOŠČÍK, Václav (referee)
In my work, I would like to close the term "Late photography". Personally, I believe that since the seventies we in the works of many artists find similar documentary strategies that relate to the concept of "Late photography". Currently, there is a certain exhaustion of this concept. For these reasons, I would like to focus on finding artists who suggest a new direction in photography while benefiting from a "photojournalist".

Global Economy Outlook - October 2016
Česká národní banka
The October 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 focus in detail on the industrial producer price index (PPI), which, alongside the consumer price index (CPI), is a key indicator of inflation on the production side of the economy. We also explain the specifics of the PPI, especially in the EU, and present a model simulation indicating the sensitivity of the PPI to a change in oil prices.

Reader's diary and ICT - a traditional teaching method in the content of modern technologies
GRÚZ, Michael
The thesis Reader´s diary and ICT a traditional teaching method in the context of modern technologies is divided into two parts. The theoretical part deals with general principles of literature, literature reception and reader´s motivation. The attention is also paid to literary and reader´s education of children at school and in their free-time, including so-called pre-reading period as well. The main focus is on the impact of modern technologies on teaching literature and the method of a reader´s diary. The exploratory part includes outcomes of two questionnaire-based researches. The first one was designed for Czech language and literature teachers at secondary and lower level grammar schools, and its aim was to describe their attitude towards assigning, checking, evaluation and further use of readers´ diaries in literature lessons. The second questionnaire was focused on the pupils´ attitude towards assigned reading in relation to so-called online literature guide-books.

Retargetable Analysis of Machine Code
Křoustek, Jakub ; Janoušek, Jan (referee) ; Návrat,, Pavol (referee) ; Kolář, Dušan (advisor)
Analýza softwaru je metodologie, jejímž účelem je analyzovat chování daného programu. Jednotlivé metody této analýzy je možné využít i v dalších oborech, jako je zpětné inženýrství, migrace kódu apod. V této práci se zaměříme na analýzu strojového kódu, na zjištění nedostatků existujících metod a na návrh metod nových, které umožní rychlou a přesnou rekonfigurovatelnou analýzu kódu (tj. budou nezávislé na konkrétní cílové platformě). Zkoumány budou dva typy analýz - dynamická (tj. analýza za běhu aplikace) a statická (tj. analýza aplikace bez jejího spuštění). Přínos této práce v rámci dynamické analýzy je realizován jako rekonfigurovatelný ladicí nástroj a dále jako dva typy tzv. rekonfigurovatelného translátovaného simulátoru. Přínos v rámci statické analýzy spočívá v navržení a implementování rekonfigurovatelného zpětného překladače, který slouží pro transformaci strojového kódu zpět do vysokoúrovňové reprezentace. Všechny tyto nástroje jsou založeny na nových metodách navržených autorem této práce. Na základě experimentálních výsledků a ohlasů od uživatelů je možné usuzovat, že tyto nástroje jsou plně srovnatelné s existujícími (komerčními) nástroji a nezřídka dosahují i lepších výsledků.

Digital circuits test optimization by multifunctional components
Stareček, Lukáš ; Gramatová, Elena (referee) ; Kubátová, Hana (referee) ; Kotásek, Zdeněk (advisor)
This thesis deals with the possibilities of digital circuit test optimization using multifunctional logic gates. The most important part of this thesis is the explanation of the optimization principle, which is also described by a formal mathematical apparatus. Based on this apparatus, the work presents several options. The optimization of testability analogous to inserting test points and simple methodology based on SCOAP is shown. The focus of work is a methodology created to optimize circuit tests. It was implemented in the form of software tools. Presented in this work are the results of using these tools to reduce the test vectors volume while maintaining fault coverage on various circuits, including circuits from the ISCAS 85 test set. Part of the work is devoted to the various principles and technology of creating multifunctional logic gates. Some selected gates of these technologies are subject to simulations of electronic properties in SPICE. Based on the principles of presented methodology and results of multifunctional gates simulations, analysis of various problems such as validity of the modified circuit test and the suitability of each multifunctional gate technology for the methodology was also made. The results of analysis and experiments confirm it is possible for the multifunctional logic gate to optimize circuit diagnostic properties in such a way that has achieved the required circuit test parameter modification with minimum impact on the quality and credibility of these tests.

Trust and Reputation in Distributed Systems
Samek, Jan ; Návrat,, Pavol (referee) ; Šafařík,, Jiří (referee) ; Hanáček, Petr (advisor)
This Ph.D. thesis deals with trust modelling for distributed systems especially to multi-context trust modelling for multi-agent distributed systems. There exists many trust and reputation models but most of them do not dealt with the multi-context property of trust or reputation. Therefore, the main focus of this thesis is on analysis of multi-context trust based models and provides main assumptions for new fully multi-contextual trust model on the bases of them. The main part of this thesis is in providing new formal multi-context trust model which are able to build, update and maintain trust value for different aspects (contexts) of the single entity in the multi-agent system. In our proposal, trust value can be built on the bases of direct interactions or on the bases on recommendations and reputation. Moreover we assume that some context of one agent is not fully independent and on the bases of trust about one of them we are able to infer trust to another's. Main contribution of this new model is increasing the efficiency in agent decision making in terms of optimal partner selection for interactions. Proposed model was verified by implementing prototype of multi-agent system when trust was used for agents' decision making and acting.

Influence of transportation on quality of delivered food (Experience of boarders)
ŽUFOVÁ, Pavlína
In this bachelor thesis I deal with the influence of transport on quality of distributed food with focus on experience of the boarders. The paper is divided into a theoretical and a practical part. The theoretical part is concerned with the HACCP system representing the preventive measures that serve for provision of health harmlessness of food in processes related to its production, treatment, storing and transport. This system is required as a part of every catering establishment. The work analyses the legislation and is concerned with duties of the operators and the persons who carry out epidemiologically serious activities while it focuses on the maintenance of their personal hygiene. In the final work I point out the potential but in fact threatening health danger of food. I classify these food risks and suggest some possibilities of elimination of such risks. The final work studies the alimentary infections that are caused mostly by wrong technological treatment or ignoring the hygienic rules. In the work I introduce and point out the hygienic requirements that should be respected, followed and fulfilled in the process and preparation of food. I further describe transport wrapping, transport of food itself and the rules of food delivery and its serving. In the practical part I use the theoretical findings from the first part of this bachelor thesis. In this part I make a brief description of the main university canteen. The K2 refectory is described in more details and I analyse the process from filling into the food containers to the process of serving the food. Simultaneously, I emphasize the temperature of particular dishes that has to be kept during the transport as well as during the process of serving. For comparison and evaluation of the results I chose a quantitative research method. This method was realised in a form of a questionnaire. I distributed the questionnaires personally to the students of the Faculty of Health and Social Studies, in building of which the K2 refectory is placed, and the students addressed near the main university canteen. The questionnaire was anonymous and contained 21 close-ended questions. Both research samples received the same questionnaires that differed only in the sequence of particular questions. In total, 220 questionnaires were handed out, 110 in each place. The percentage of questionnaires returned was 100 %. Considering the fact that I eliminated two questionnaires from the K2 refectory and five questionnaires from the main university canteen due to their wrong completing, the real percentage of questionnaires returned in the K2 refectory was 98 % and in the main university canteen 95 %. The particular data obtained in the questionnaires were further processed in Microsoft Office Excel and Microsoft Office Word. The aim of this work was to chart the experience of the boarders in the K2 refectory who consume fresh, although delivered food. The process of transportation could debase food therefore the quality of food might decrease. The experience of these students were subsequently compared with the experience of students who board in the main university canteen where the food is prepared (cooked) and consumed immediately. Based on two main goals, I determined three hypotheses: Hypothesis number 1: Transportation of food has negative influence on the sensorial qualities of food. On the basis of the statistical testing, this hypothesis was rejected. Hypothesis number 2: Students prefer fresh food. After the statistical testing, this hypothesis is valid. Hypothesis number 3: Students do not feel the difference between fresh and delivered food. This hypothesis is valid as well. The results gained and processed during my research will be presented to the university canteen staff that could use the findings in practice.

Social media influence
BAUEROVÁ, Milada
This diploma thesis deals with social media, specifically with what influence they have on an individual´s decision making while choosing a university. There are 87 universities in the Czech Republic, each of them offers unique study programmes and each one is specific, nevertheless, if they are divided according to subject-matter focus, for instance divided only into universities focused on the study of economy, it is difficult to differentiate which one will be the best choice for a possible student. For the purposes of this diploma thesis, University of South Bohemia has been chosen, and Czech University of Life Sciences Prague has been chosen for the purposes of comparison. The main goal may be specified as an analysis of social media influence during the choice of a university, and to design some useful recommendations based on the results. Other goals of this thesis are: - To find out how universities use social media, - To find out how students get involved in social media happenings. The results for this thesis will be obtained on the basis of a marketing research via a questionnaire survey among the students of the University of South Bohemia and of the Czech University of Life Sciences in Prague. Based on these results an analysis and a comparison will be carried out, finding out how strongly social media influences students when choosing a university, whether students themselves participate in social media happenings and what else may be improved by the universities.
