Analysis of the use of new technologies for visual communication and their social impact
Kadlecová, Petra ; Sigmund, Tomáš (advisor) ; Truhlář, Filip (referee)
The work focuses on the analysis of new technologies, which are used in visual communication. This is especially the description, characterization and their use. Another section focuses on social trends that permeate contemporary Western society, and their relationship with new technologies in the field of visual communication. It deals therefore also examines the social changes and changes in the perception of individual development and dissemination of new technologies causes. Describes the important role of visual communication in today's world and the changes in society due to widespread use of modern technology. The aim is to make the analysis and therefore a comprehensive overview of new technologies and their use in the field of visual communication. Finally, the work seeks to estimate the next direction of new technologies in the field of visual communication and create a prediction of further development in the future.

Additive Group-Contribution Methods for Predicting Properties of Polymer Systems
Bogdanić, Grozdana
This overview presents group-contribution models for predicting properties of pure polymers, polymer/solvent and polymer/polymer mixtures. The state of art can be easily considered taking into account that polymer solutions and blends are complicated systems, with frequent occurrence of LLE in many forms (UCST, LCST, closed loop), significant effect of temperature and polymer molar mass in phase equilibrium, the free-volume effects, and other factors causing these difficulties. The choice of a suitable model depends on the actual problem and demands, especially on the following: type of mixture (solution or blend, binary or multicomponent), type of phase equilibrium (VLE, LLE, SLE), conditions (temperature, pressure, concentration), type of calculation (accuracy, speed, yes/no answer, or complete design). The performance of various models and their range of application will be discussed.

ANALYSIS OF THE COMPANY USING TIME SERIES METHODS AND FINANCIAL ANALYSIS
KÚNOVÁ, Lucie
The goal of my bachelor work was to analyze the company Profi - Service, Ltd., which I chose for it. I have divided the work into two parts. In the first part I focused on the analysis of time series development of the profit. Firstly described the behavior of this series and modeled it using different models. The first model I focused on is the small trend method. Then I created model with seasonality regression. In the end of this section I will make a spectral analysis. Based on these models, I tried to predict the future development of the profit. For the calculation of some values I used program Statistika. In the second part, I focused not only on the financial analysis of the company Profi - Service, Ltd., but for making comparison, I made financial analysis for the company Uniclean, Ltd. too. The resulting values of indicators were also compared with industry averages. I started with evaluative indicators, next I made the analysis of funds and finaly I made a pyramidal decomposition of indicator the return of equity.

Prediction of solar activity in the 24th and 25th cycles
Střeštík, Jaroslav ; Mikulecký, M.
In the half of nineties we prepared a prediction of solar activity in cycles No 23 to 26. For this prediction we used the data from 1500-1995 representing 10 significant period lengths with lowest p-values. Using the superposition of these sine waves the data of 1500-1995 were excellently fitted. The prediction for 1996-2040 was constructed as an extrapolatlon of this course. We predicted that cycles No 23 and 24 wtll be longer and the value of sunspot numbers in the maximum will be lower than that in the cycle No 22. These predictions have been so far roughly fulfilled, except only the maximum of the 23rd cycle appeared in reality a little earlier. This is why the descending part of the 23rd cycle observations found itself closely under the 957o tolerance corridor of our prediction. Using now the data since 1500 till 2010 and the same prediction method we prepared anew prediction for the cycles No 24 and 25. Both cycles should be also longer, similarly as the cycle No23 in our first predlction as well as in the reality. Values of sunspot numbers in maxima should be even lower.

Theoretical Background for Predicting the Properties of Petroleum Fluids via Group Contribution Methods
Bogdanić, Grozdana ; Pavlíček, Jan ; Wichterle, Ivan
The major problem encountered in the petroleum industry lies in the proper thermodynamic representation of rather complex fluids. In this work, the UNIFAC group contribution method for predicting the properties of such fluids has been exploited as a basis for their description in terms of model compounds. Standard thermodynamic procedures are used to estimate the critical properties, acentric factors, and molecular weights for the model compounds. In such a way, the already available generalized methods can be used for calculations of the phase equilibrium in complex petroleum mixtures.

Analysis and Modeling of Macroeconomic in the Czech Republic
Novotný, Dalibor ; Bartošová, Jitka (advisor) ; Voráček, Jan (referee)
Main goal of my dissertation was take a close look at progress of several economics indicators from 1993. I also decided to analyse key factors wich mainly influence these ecnomics indicators. This work is based on classical model IS-LM-BP which is most suitable because of its logic and siplicity. This work is constituted by three parts: first describer theoretical base, second part is dedicate to analysis economy from 1993 and third part is focused on macroeconomical model of Czech economy. Theoretical part presents main parts of national economy (e.g. Gross domestic product, Unemployment, Inflation, Balance of Payment, etc.) including detailed structure of these key indicators. Such a detailed description was importent because of recent modelling and was signiicant for better choice of variable. In second part of this work we analyse economic development from 1993 and we focused on main causes of change. Main goal of this part was exploring of global progress and better understanding to all indicators in the small-open-economy. In final part of dissertation are created several models which are based on historical data and predict progress for nearest future. Because fact that source data are mainly till 2010 we were able to test our models on real data of year 2011. In spite of economical progres in last few years we can say that large majority of results from our models are in compliance with our expectation. However in some cases ware results diferent, we identifed key resons for these results.

Funding of basic transport services
Šperňák, Filip ; Zelený, Lubomír (advisor) ; Bačák, Otakar (referee)
The aim of this thesis is to analyze the funding of basic transport services, which will be analyzed through the real business DPMO, a.s.. The report is divided into a theoretical and a practical part. The theoretical part explains the issue of providing public transport services and its compensation from the customer. It also includes a methodology for assessing the financial situation, with horizontal and vertical analysis ratios and an analysis of net working capital. To create comprehensive conclusions that are credible, the bankruptcy and creditworthy models are utilized. The practical part includes the the meticulous results from the DPMO analysis in the years 2006 to 2010, and the conclusion consists of a prepared summary. The last chapter includes a prediction for the next period using a model that predictss the time span durinch which the analyzed company is thriving if the previous trends are maintained, and if the compensation costs are not altered.

An evaluation of real GDP growth forecasts
Kačmareková, Monika ; Jablonský, Petr (advisor) ; Dobrovolný, Marek (referee)
This paper is aimed at verifying the reliability of real GDP growth forecasts for Czech Republic periodically published. Concretely the prediction of different groups of institutions have been examined. It includes analysis of forecasts for the period 2003-2011. Evaluation criteria for assessing their accuracy consist of summary statistics, directional accuracy rate and graphical illustration of avereged prediction. These evaluation methods are important for the hypothesis verification. It has been demonstrated the ability to deliver more accurate forecasts in comparison with earlier period in a specific horizon, next, a rising precision of predictions with declining time horizon, systematic underestimation of forecasts in the time of expansion and overestimation in the time of recession. At last, the conducted analysis displays that czech institutions are doing not considerably better in forecasting real GPD growth.
