Solar Energy Applications in Houses
Jankůj, Tomáš ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
This thesis is focused on photovoltaics and photothermics. Their source is solar radiation that belongs to the category of renewable sources. At present, great emphasis is placed on ecology and economics. For this reason, renewable sources are coming to the foreground. In the first part of the bachelor thesis, types of photovoltaic cells, technology and their efficiency are presented. Furthermore, the principle and construction of photovoltaic and photothermal systems are described. The second part describes the design of the energy solution of a family house using solar energy.
News Topics Tracking
Bílek, Karel ; Bojar, Ondřej (advisor) ; Holan, Tomáš (referee)
In this thesis, I try to find a definition of a news topic to make topic detec- tion implementable and its quality measurable. I describe various methods - a "simple" words counting, optionally with stopwords. I also describe TF-IDF and the text categorization problem. I touch the subject of text clustering. Then I briefly describe approaches called latent semantic indexing and la- tent Dirichlet allocation. The thesis includes my experiments with "simple" words counting, TF-IDF and text categorization on database of articles from several online news websites; I also describe the creation of this database. Precision and recall are used as a metric to text categorization approach. 1
Electronic reading-room
Korcsok, Peter ; Holan, Tomáš (advisor) ; Horký, Vojtěch (referee)
Title: Electronic reading-room Author: Peter Korcsok Department: Department of Software and Computer Science Education Supervisor: RNDr. Tomáš Holan, Ph.D. Abstract: We have created an Internet application that allows registered users to share information about scientific articles. Data necessary for standard bibli- ographic record are stored for each article; any files with the text of the article in PDF or PostScript format are saved directly on the server. Articles can be sorted into categories arranged in a treelike structure. Users may rate the artic- les using marks and commentaries and discuss them. The application provides a comfortable search in stored articles; user is able to save the search parameters for future use. Addition of new article can be done using a web form or by sending an e-mail message containing all necessary data in the correct format to address of the application. Some users are selected as administrators who manage ac- counts, categories and other application settings. The work is designed in PHP and uses MySQL database. Keywords: articles, web, database
Automatic System for Downloading of Scientific Papers
Šebela, Ondřej ; Svoboda, Pavel (referee) ; Rozman, Jaroslav (advisor)
Goal of this work is the creation of application designed for automatic downloading of scientific papers by using online databases of scientific publications. This work is studying the structure and means of retrieving information about scientific documents. It also describes the final application and rates it based on results of testing.
Proposal of Website
Caha, Lukáš ; Slatinský, Miroslav (referee) ; Řešetková, Dagmar (advisor)
This bachelor´s thesis deals with the design of suitable website for Czech ice hockey club HK Sumperk. The web presentation is designed for fans and other visitors, with all information about hockey in Sumperk. Team of editors will publish game schedule, results, game reports, interviews, press releases, statistics etc. on the website. I also focus on advertising positions for club partners and sponsors that are essential for economic survival of the club.
Scientific Web Portal Generator
Mertel, Ján ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)

As a part of the thesis there is a support for portal personalization according to various options. Project focuses on working with articles generally, whose references are kept in database, and further actualization of the portal.
Development and design of a modular battery box.
Rozinek, Josef ; Buday, Vladimír (referee) ; Porteš, Petr (advisor)
Tato práce se zabývá problematikou battery packů. V první části popisuje návrh battery packu z hlediska volby baterií, jejich tvaru, velikosti, typu a konfigurace zapojení. Dále uvádí vliv těchto charakteristik na výkonnost battery packu a jeho spolehlivost. Zabývá se problematikou termálního managementu battery packů a jeho vlivu na životní cyklus baterií. V druhé části se zabývá praktickým návrhem konceptu battery packu pro Lithium-polymerové baterie. Kalorimetricky je zde zjištěno množství produkovaného tepla při vybíjení, které je poté využito v CFD simulaci chlazení článku.
Device for measurement of electrochemical cells characteristics by the cyclic voltammetry
Kučera, Vojtěch ; Bilko, Radek (referee) ; Lábus, Radek (advisor)
The thesis deals with observation of cells parameters. One of the potential solutions for observing the characteristics of cells are utilization the electrochemical analyse called voltametry. Its fundamental consists of loading variable voltage in between two electrodes dipped in electrolytic solution and monitoring flowing current. The point of the thesis is to build up the measuring workplace, which can provide this measurement. We suggest utilization of modern laboratory technique and connection the measuring instruments with PC. The first part of the thesis deals with theoretical knowledge of used functions and describes theirs mathematics definitions. The second part deals with proceeding of workplace realization, instrument connection with PC and development application in computer’s language. Result is measuring workplace, which can provide observing cells according to entered parameters.
Bible studies on Czech universities since 1989 (the institution, personalities, research work)
The main part of the thesis is a research focused on describing research activities at Czech universities since 1989 to the present time, i.e. until the end of 2013. The thesis describes the work and publications of all personalities who participated in the research within the field of Bible Studies.
Analysis of an environmental conflict - opinions of main groups of the inhabitants in the pond water area on the subject of the presence of cormorants (fishermen and holidaymakers) and media analysis
ŠÍPOVÁ, Martina
The thesis was chosen on the basis of the continuation of the bachelor´s work. This thesis is focused on the literature search of problems of the conflicts between the protection of cormorants and the interest of fishery, further on the media analysis in the Czech Republic and finally on the processing of opinions of various groups of respondents (holidaymakers in the area called ´Třeboňsko´ and Czech fishermen). The opinions of questioned people were obtained from controlled interviews written down and processed in the questionnaires. The available information shows that a number of the protected cormorants is increasing not only in the Czech Republic but all over the world. The increase of the number of cormorant population causes problems especially to fishery, because cormorants cause the damage by catching fish stock. These conflicts in the problem area are mostly promoted in the media. In the problem area there are important opinions of the key groups of inhabitants. Groups of questioned people demonstrated their knowledge: holidaymakers in the area called ´Třeboňsko´ have basic knowledge in cormorants and problems caused by cormorants. On the contrary, fishermen are well-informed about the problem. The fishermen are more interested in the problem. Media are very important for solving conflicts and forming opinions of various groups of people. Media analysis showed that most spokesmen, who initiated writing newspaper articles were just fishermen. Therefore the articles on the cormorants are negative and without opinions on the spokesmen as member of general public or academics. Results of the sociological analysis have feed back on the results of the media analysis. It was found out that in the Czech Republic there had not been drawn up any management of fish protection againts cormorants. That is why I prefer to suggest the management in the near future. I recommend to follow the existing foreign management, forexample, in Great Britain. Further, I propose to change the Czech legislation for lower payment of the compensation for the damage caused by cormorants.
