Application possibilities of LNVGA programmable amplifier
Sobotka, Josef ; Hanák, Pavel (referee) ; Jeřábek, Jan (advisor)
This thesis deals with the theoretical description of the qualitative characteristics and parameters of some modern active elements, also discusses the theory of signal flow graphs at the level applicable for the following frequency filter design methods. The thesis is also generally discussed the issue with the circuit simulator PSpice modeling theory and voltage amplifiers on the basic 6-levels. The practical part of the work is divided into two parts. The first practical part is dedicated to design four levels of simulation model of components LNVGA element. The second practical part contains detailed theoretical proposals for three circuit structures implementing the frequency filters 2nd order (based on the basic structure of the OTA-C) using signal flow graphs with configuration options of Q and fm based on the parameters of active elements in the peripheral structure and their verification with prepared LNVGA model layers.

Methods for Segmented Image Processing
Štěrba, Radek ; Číka, Petr (referee) ; Zukal, Martin (advisor)
This work deals with the representation of segmented images using graphs. Different segmentation methods used in processing visual information are described here. Today is mathematics increasingly needed. This fact is not omitted, basic information of graph theory are described in this paper. The second part of this work is practical. It contains a survey of libraries processing graphs. Further the data structures for describing the segmented image are described. Last but not least, there is also described the formation and properties of the operators designed for environment RapidMiner that fill these structures.

Systems for remote measurement in power engineering
Hudec, Lukáš ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
The work deals with the measurement and management in power. Provides an introduction to the problems of remote meter reading, management, and describes the current situation in the field of modern technologies Smart metering and Smart grids. It also analyzed the issue of collection of networks and data collection from a large number of meters over a wide area. For the purpose of data transmission are described GPRS, PLC, DSL, ... Further, there are given options to streamline communication. This area is used hierarchical aggregation. Using k-means algorithm is a program designed to calculate the number of concentrators and their location in the group of meters. The finished program is written in Java. It has a graphical interface and shows how the calculation is conducted. To verify the results of the optimization program is given simulation model in OPNET Modeler tool. Audited results are described in the conclusion and can deduce that using the optimization program is to streamline communications.

Application of graph theory to the design and optimization data network architectures
Římský, Adam ; Trzos, Michal (referee) ; Novotný, Vít (advisor)
This masters'sthesis deals with graph theory and utilization of this theory for design and optimization of data network structures. Introduction chapter describes graph theory in general view, i.e. fundamental terms used for graph description, graph distinguishing, etc. Next part describes graph algorithms, for example a shortest path finding. After this I write about actual routing protocols where the graph algorithms are used. Last but one part deals with queuing theory and final part describes practical presentation of using graph theory for design and optimization of data network structure in Matlab programme environment.

Visualization of the MBI data
Syrovátka, Adam ; Novotný, Ota (advisor) ; Pour, Jan (referee)
The topic of this master's thesis is to design and implement a web application for visualization of relationships between the MBI objects in order to deliver additional functionality to the web portal of MBI - Management of Business Informatics. The first part introduces the concept of MBI and ranks the functionality of the MBI web portal from the view of user queries and visualization capabilities. The queries which are identified as the most difficult are set as the primary functional request for the new web application. The second part contains the design and implementation of the web application. Both functional and non-functional requirements are specified, including the design of user interface and visual graph searching. Based on these requirements, a suitable application architecture is selected together with a graph database and suitable query library and visualization library. The application is implemented with the selected technologies and tested against the initial requirements. The last part includes a service manual and a user documentation which describes the complete application functionality and provides a use case scenario.

Statistical methods in R
Jiráň, Robin ; Löster, Tomáš (advisor) ; Bílková, Diana (referee)
This thesis deals with the most important statistic methods, ways of calculating and syntax in the environment of R statistic programme. The initial parts of the bachelor thesis content a brief theoretical basis for the main chapters of the practical part. In the following chapters the use of R programme itself for calculating statistic tasks is explained. The particular parts of recording functions in R programme are presented, important arguments are described and both text and graphical inputs are displayed.

Modelling functions of two variables
SAMCOVÁ, Soňa
In this bachelor thesis we are working with programs Wolfram Alpha, wxMaxima and Google. These programmes are accessible without any licences. We are trying to process basic summary of function of two variables and at the same time provide some information about these functions. In the end of the thesis programmes are compared and evaluated. The thesis is focused on helping the students for better orientation during the study of function of two variables.

Social networks and social bullying
KUBÍČEK, Petr
In my thesis I have focused on the issue of social networks and (social) bullying at elementary schools. In the first part of my paper I summarize the theoretical background and provide an overview of findings and opinions published by experts in relation to the issue of bullying and cyber-bullying, while in the second part of my paper I analyze the results of a research performed with the use of an anonymous questionnaire at four (4) elementary schools in the South Bohemia Region (Jihočeský kraj). The schools involved in the research were: two (2) schools with less than 270 pupils in the Prachatice region, one school with more than 270 pupils in the town of Prachatice and one school with more than 270 pupils in the city of České Budějovice. The purpose of the questionnaire investigation was to collect information on the extent in which aggressive behavior and cyber-bullying appear among pupils attending the 5th through 9th grades of the elementary school (age range 11-15). In the final part of the thesis I provide an overview of the results obtained through the research with the use of a BPAQ questionnaire (BussPerry Aggression Questionnaire and aggressive acts).

Extremes of two-variable functions --- a digest of solved examples
SEKAL, Tomáš
The topic of this bachelor work is to create a collection of exercises on the extremes of functions of two variables. It focuses mainly on local extremes. Exercises are ordered from easiest to more difficult. For each example there is solution procedure presented and illustrated with 3D graphs of functions, created using the mathematical program Maple. In the very beginning is provided "first aid" in the form of instructions for solving this kind of examples. At the end are included in "nontraditional" examples from mathematics and physics.
