Water supply without a residual disinfectant
Rajnochová, Markéta ; Pikal, Martin (referee) ; Ručka, Jan (advisor)
The diploma thesis focuses on the water distribution system functioning without chlorine-based disinfectant. This thesis contains research of documented cases of examples of drinking water distribution systems both abroad and in the Czech Republic, which do not use disinfectants. Moreover, the thesis pay attention to chlorine and its effects on bacteria. The thesis deals with the first assessment of water supply structure, which determines whether the water supply structure is suitable for operating without disinfectant. The thesis describes the process of transition to the disinfectant-free operation and determines the undesired events, which may occur with the ending of the use of disinfectant. As a part of the research, the thesis examines the water supply system in village Kateřinice, to determine if it is suitable for operation without disinfectant.

The study of selected sewer network in an urbanized catchment
Korytář, Ivo ; Habr,, Vladimír (referee) ; Raclavský, Jaroslav (advisor)
This paper deals the case study of the chosen sewer system in the village Starý Mateřov. The study solves passportization of sewer, what is the base for creating technical condition mainly for three selected sections. According to the results from the technical conditions of the three selected sections were suggested suitable options of redevelopment. The options are compared in financial way. The last chapter suggests two possibilities how to deal with the sewage. The first option consists of the transferring waste water to the waste water treatment plant in Pardubice - Semtín. The second option suggests building a new waste water treatment plant in Starý Mateřov. The options are compared in financial way.

Managing Mobile IP enabled networks with SNMP protocol
Závodný, Ondřej ; Vajsar, Pavel (referee) ; Skořepa, Michal (advisor)
The content of this thesis is to research possibilities of using SNMP for management of Mobile IP activated entities. The first two chapters deal with theoretical analysis of Mobile IP protocol, and Simple Network Management Protocol. The Mobile IP protocol analysis focuses especially on the elements Home agent and Foreign agent. In the SNMP chapter the analysis focuses mainly on ways to exchange messages. Another part of the document is devoted to a description of laboratory networks com- posed of routers Cisco 1841 and the configuration of them. Finally is described the programmed application to manager these devices in JAVA, which is included in Annex. The program periodically sends SNMP queries and finds relationships between the Home agent and the mobile nodes, and between the foreign agent and the mobile nodes. The application has a user-friendly interface that is shown on the attached flash animation. Finally, the thesis summarizes the concepts described in previous chapters and the goals to achieve.

Algorithmic Trading Using Twitter Data
Kříž, Jakub ; Plchot, Oldřich (referee) ; Szőke, Igor (advisor)
This master's thesis describes creation of prediction system. This system predicts future market development based on stock exchange data and twitter messages analysis. Tweets from two different sources are analysed by mood dictionaries or via recurrent neural networks. This analysis results and technical analysis of stock exchange data results are used in multilayer neural network for prediction. A business strategy is created and tested based on results of this prediction. Design and implementation of prediction system is described in this thesis. This system achieved revenue increase more than 25 % of some business strategies by tweets analysis. However this improvement applies for certain data and timeframe.

Gradient Boosting Machine and Artificial Neural Networks in R and H2O
Sabo, Juraj ; Bašta, Milan (advisor) ; Plašil, Miroslav (referee)
Artificial neural networks are fascinating machine learning algorithms. They used to be considered unreliable and computationally very expensive. Now it is known that modern neural networks can be quite useful, but their computational expensiveness unfortunately remains. Statistical boosting is considered to be one of the most important machine learning ideas. It is based on an ensemble of weak models that together create a powerful learning system. The goal of this thesis is the comparison of these machine learning models on three use cases. The first use case deals with modeling the probability of burglary in the city of Chicago. The second use case is the typical example of customer churn prediction in telecommunication industry and the last use case is related to the problematic of the computer vision. The second goal of this thesis is to introduce an open-source machine learning platform called H2O. It includes, among other things, an interface for R and it is designed to run in standalone mode or on Hadoop. The thesis also includes the introduction into an open-source software library Apache Hadoop that allows for distributed processing of big data. Concretely into its open-source distribution Hortonworks Data Platform.

Application of DSSAT model to simulated thermophilic crops in central and southern Europe
Potop, V. ; Mateescu, C.D. ; Türkott, L. ; Zahradníček, Pavel ; Boroneant, C. ; Constantinescu, F. ; Iamandei, M.
This study presents applications of DSSAT version 4.5 software package to simulate thermophilic crops. The results are used to identified adaptation options to reduce impacts of climate changes, pest and diseases in thermophilic crops in the central and southeastern Europe, specifically in Elbe River lowland and Romania. For the Czech Republic, experimental research at farm level includes: (1) testing thermophilic assortment of vegetables in Elbe lowland conditions; (2) monitoring the meteorological data, phenological phases, soil characteristics, leaf area and the amount of aboveground biomass on farmer vegetable fields. For Romania, the focus is put on crop water use efficiency under current and future climate scenarios for thermophilic species (maize) in different agricultural sites from south and south-eastern regions. CERES Maize and CROPGRO-vegetables modules embedded in DSSAT were used.

Proposal of river training of a small watercourse in the basin of the Morava
Mlčochová, Zuzana ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with an appraisal of capacity of channel and design of suitable measures for environmental protection. Solved segment is located in the channel of Český potok in RK 0,000 – 6,366. The channel is flowing through villages of Čelechovice na Hané, Smržice a Držovice in solved segment. Within own solution the locality was divided into three partial sections, which is enabling clearer description of the proposed measures. Flood measures are proposed in several variants for each partial section. Calculations of flow capacity and water surface for the selected N-year flows were performed by using the program of HEC - RAS 4.1.0. Proposed solutions to flood measures are processed in the drawings documentation.

Energy security of China focusing on natural gas
Andrsová, Nicola ; Čajka, Radek (advisor) ; Müller, Štěpán (referee)
The diploma thesis deals with the energy security of China, mainly with the question considering energy mix, consumption, infrastructure network and diversification of importers in natural gas field. The analysis of research question is done mainly from the data of international energy organizations, from the Chinese government data and other sources, which enable to describe mentioned problems. From the People's Republic of China perspective, it focuses on the detailed description of gas pipeline infrastructure, importers and subjects, which are involved in energy sector. Risks and threats, which should occur from signed partnerships or projects, were taken into consideration too. The aim of this work is to define and evaluate the energy security of PRC, its energy policy mainly in natural gas field when considering present situation as well as possibilities for the future. Than the diploma thesis outlines the role of natural gas in Chinese energy mix, state of the gas sector in China and evaluation of projects, which take place in China's gas sector or will occur in the future.
