Jedličková, Marie ; Zahradníček, Pavel (referee) ; Koch, Miloš (advisor)
The existence of an information strategy in a company helps to manage the information system and thereby positively affect the achievement of global strategic goals of the company and its overall market success. This thesis focuses on the creation of an information strategy in a company based on the Czech market, in the sector of small and medium-sized companies. The first part presents theoretical basis of the topic. The second part is devoted to a detailed analysis of the current condition of the company and its potential, which makes it possible in the third part, to identify appropriate amendments, which will be implemented within the enterprise information strategy. The proposed changes will be consistent with the overall strategy of the company and lead to better support of the future development of the company in the market.

Structural integrity analysis of storage tank using FEM
Zahradníček, Pavel ; Nováček, Filip (referee) ; Stuchlík, Viktor (advisor)
This diploma thesis deals with the storage tanks for petroleum products. The introductory part is devoted to the distribution of the storage tanks, associated standards and maintenance of tanks. Another part goes about the analysis of real case of a tank collapse. There was created a 3D model of the collapsed tank according to the measured values in the tank. It was created a tank shell model by drawing documentation and analysis of the results of the accident investigation using the finite element method (FEM) by program ANSYS. Calculation was performed on the buckling resistance of the structure according to ČSN EN 1993-1-6 and its comparison with the results of FEM analysis in ANSYS. The aim of the study was to find the critical condition of the structure and determination of the critical internal underpressure and overpressure. At the end there were determined measures for safe operation and settings of the valve members.

Stochastic Weather Generators and Regional Climate Models: Rivals or Allies?
Dubrovský, Martin ; Štěpánek, Petr ; Meitner, Jan ; Zahradníček, Pavel
The paper demonstrates 'collaboration' between the stochastic weather generator SPAGETTA (WG) and Regional Climate Models (RCM) in analysing impacts of Climate Change (CC). In the first part of the paper, the generator is compared with the ensemble of 19 RCMs in terms of their ability to reproduce 11 spatial temperature and precipitation indices in eight European regions: the indices are based on registering days and spells exhibiting spatially significant occurrence of dry, wet, hot or cold weather, or possible combination of dryor-wet and hot-or-cold conditions. The obtained results indicate that both methodologies provide weather series of comparable quality. In the second part of the paper (which was done only for the Central Europe region), the WG parameters are modified using the RCM-based CC scenarios and the synthetic weather series representing the future climate are produced. This experiment is based on a set of CC scenarios, which consist of changes in selected combinations of following characteristics: (1) mean temperature, (2) temperature variability, (3) daily average precipitation (considering only wet days), (4) probability of wet day occurrence, (5) spatial lag-0 and lag-1day correlations of temperature and precipitation series. The synthetic series generated for each version of the CC scenario are analysed in terms the above mentioned spatial validation indices, the stress was put on effect of each of the five component of the CC scenario on individual validation indices. The results of the experiment indicate that the changes in temperature means is the main contributor to the changes in the validation obviously, except for the purely precipitation-based indices. Positive changes in the lag-0 and lag-1day correlations of both temperature and precipitation are the second most significant contributor to the changes in the validation indices.

Modeling the impacts of combined climatic events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in the decision support system in the field of agrotechnology transfer - DSSAT
Potopová, Vera ; Muntean, N. ; Chawdhery, M. ; Trifan, T. ; Zehnálek, P. ; Soukup, J. ; Potop, I. ; Zahradníček, Pavel ; Možný, Martin
Modeling the impacts of combined climate events on the growth, development and yield parameters of field thermophilic vegetables and oilseed rape in a decision support system in the field of agrotechnology transfer - DSSAT. This book will introduce you to the latest information technologies and their applications in agriculture, including decision support systems, crop simulation models and other computer tools. It should also help you to solve problems at the regional level on issues related to crop production and other issues related to agriculture, natural resource management and cropping systems and food security, as well as issues related to climate change and variability. This professional book offers users the appropriate supplementary material to enable them to continuously meet the demands of a changing climate. The book is divided into two parts, theoretical and practical. The theoretical part summarizes basic information about simulations of crop production, water and nutrient management, climate risks and environmental sustainability. In the practical part, the procedures for working in the DSSAT program (Decision Support System for Agrotechnology Transfer) are presented.

Trnka, Miroslav ; Kudláčková, Lucie ; Čermák, P. ; Balek, Jan ; Novotný, Jan ; Homolová, Lucie ; Semerádová, Daniela ; Brovkina, Olga ; Štěpánek, Petr ; Zahradníček, Pavel ; Skalák, Petr ; Bláhová, Monika ; Benáček, Patrik ; Fischer, Milan ; Sedlák, Pavel ; Janouš, Dalibor ; Žalud, Zdeněk ; Marek, Michal V. ; Možný, M. ; Hájková, L. ; Chuchma, F. ; Knozová, G. ; Beranová, J. ; Zatloukal, V. ; Albert, J. ; Mašková, R. ; Cienciala, E. ; Vizina, A. ; Nesládková, M. ; Melišová, E. ; Hanel, M.
The methodology formulates a procedure for assessing the risks of the occurrence and spread of natural fires in the immediate vicinity of surface sources of drinking water. The methodology\nproposes methods for estimating the consequences of natural fires on surface water quality, forecasting the change in the risk of fires due to climate change and the procedure for determining the risk of secondary pollution of reservoirs due to changes in run off after a natural fire. On this basis, the methodology proposes and diversifies preventíve and operational measures.The measures were designed in connection to modeling results for the Hadce pilot síte near the Švihov reservoir and the experience with the adverse effects of extensive deforestation on the water quality in the Vranov and Vír reservoirs.

Study of Thermal Comfort in the Urban Environment
Šubík, Štěpán ; Holtanová, Eva (advisor) ; Zahradníček, Pavel (referee)
This thesis is written to compare indices, which describe the perceived temperature of human body in thermal environment and apply them to study the thermal comfort of city inhabitants. The thesis is divided into five parts. In the first part, many thermal indices are presented and classified into empirical, commercially used or analytical indices by their definition. The practical usage of thermal indices is mentioned in the next chapter. In the third chapter, the most suitable thermal indices for describing the urban ther- mal comfort are found. Those are UTCI, PET, PT, SET* and mPET. Thermal index mPET .has been chosen to be used further in this study. The fourth chapter includes the application of mPET on meteorological data from Prague, Berlin, Hamburg, Nürnberg, Köln and Frankfurt. The frequencies and long- term behaviour are studied as well as the effect of the street canyon for Prague's streets Dělnická, Rohanské nábřeží, Legerova and Vinohradská. The last part discusses the results. The thermal comfort in Prague and Berlin, to- gether with the effects of the street canyon in Prague are studied more closely. It was found that in Prague, Berlin, Hamburg, Nürnberg and Frankfurt, the frequencies of evening thermal discomfort, in terms of heat stress, are higher in the cities than in sur- rounding areas...
