Multi-criteria decision in a choice of white electronics
Slabochová, Eliška ; Brožová, Helena (advisor) ; Andrea, Andrea (referee)
This bachelor thesis deals with multi-criteria decision in a choice of white electronics and is divided into two main parts. The first part is a literature review and the second part is an analytical part named White electronics for students household.
The first, theoretical part is dealing with basic issues, in which are explained fundamental terms of decisions, multicriteria decision and multicriteria analysis of options. The greatest attention is given to chapter of multicriteria evaluation of alternatives. In this chapter are described terms like variant, criterion or weight. This chapter included clasification of multicriteria analysis of options, methods of determining the weights of criteria and methods, which deal with multicriteria analysis of options. The biggest part of these methods is about the method of weighted sum. This method was used for calculations in the analytical part. In the last part of the literature review is described program MCAKOSA. This programme was used for the second part of bachelor thesis.
In the analytical part are explaned results of questionnare survey. This survey is named White electronics for students household. Parametres of selected types of appliances and choice of the most appropriate variants of this appliances are described in the analytical part. The choice had two steps. The first step was assessment of weights for each criterion by scoring method. The second step was choice of variants by method of weighted sum.

Student accounts evaluation
BEDNÁŘOVÁ, Michaela
The goal of this work was to evaluate the order of student accounts in terms of advantegousness, which are offered by banks on the domestic banking market. Not only theoretically, but also using quantitative methods. Firstly, the current offer of students products on the domestic market was explored, then a survey among some students was made in order to determine which student accounts are the most favourite ones, most commonly used and why. By using methods multiple-criteria evaluation of alternatives clients can make an easier decision when choosing from a large number of specified criteria. Afterwards, an appropriate evaluation criteria were fixed and evaluated in terms of profitability of individual alternatives by using methods of multiple criteria evaluation. For all analysed students, the account called - U konto pro mladé from UniCredit Bank was clearly selected as the best one. On the contrary account FRESH from Česká spořitelna appeared to be the mist disadvantageous one. According to the questionnaire, this account is owned by the majority of young respondents.

The use of numerical representations in processing of nucleotide sequences
Košíček, Adam ; Maděránková, Denisa (referee) ; Kubicová, Vladimíra (advisor)
Conversion of DNA sequences for appropriate representation is important task before initiation of analyzes and further processing. The main goal of this work was to get familiar with types of numerical and graphical representations and their application for DNA analyzes. In consideration of great volume of methods and procedures, only a few were chosen for this work. Some methods can not be classified only as numerical or graphical representations, because of option allowing them to be converted into both of these representations. These methods were classified as graphical representations. Phylogenetic trees were programmed for chosen methods to compare its precision. Outcome of this work is summing up the results.

Extending Access Control List in Dokuwiki
Macháč, Ondřej ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The goal of this bachelor thesis is to introduce the Wiki systems, especially DokuWiki. It deals with history, legal aspects and possibility to create pluggable modules (alias plugins). Plugins are also main theme of this work. At first, a simple plugin for user access rights is designed. Afterwards is extended plugin's functionality with advanced settings of permissions and is also created the ability of automatic user login based on specific entry informations.

Use of value engineering elements for realization of building in the municipality
Chytková, Markéta ; Hanák,, Tomáš (referee) ; Puchýř, Bohumil (advisor)
The aim of my thesis Use of value engineering elements for the realization of buildings in the municipality is to compare the evaluation methods of procurement in municipality and evaluation methods using elements of value engineering. A tender for reconstruction Šubertovo square was realized in the city Dobruška. In the thesis is shown way of evaluation of competing offers of the city Dobruška itself in sublimit simplified procedure and evaluation of competing offers by selecting more evaluation criteria and selecting the best offer with the highest degree of effectiveness.

Using wavelet packet transformation for image compression
Kučera, Michal ; Rajmic, Pavel (referee) ; Kyselý, František (advisor)
The need for storing and transferring digital image data is still growing nowadays. The Compression is necessary to achieve effective usage of transfer and storage capacity. This Bachelor’s Thesis is concerned with compression method based on wavelet packet transform, which is derived from wavelet transform. It is focused especially on best basis search algorithms from whole wavelet packet tree. There is a comparison between 6 best basis and near-best basis search criterions by R. R. Coifman, M. V. Wickerhauser and C. Taswell in this thesis, which is achieved by using Matlab environment based program. The program was created for testing and demonstrative purpose only and that’s why it contains certain limitation such as only black and white image processing and its limited resolution. There is applied constant threshold on testing image after the several best basis criterions application. The Mean Squared Error is used for comparing outcome quality of compressed and original image. The function that acquires minimal Mean Squared Error is considered the best best-basis search criterion in term of visual quality. The results show that some of the Taswell’s functions significantly improve the visual quality of the image at the price of worse compression ratio against common Shannon entropy.

Control of non-stable Systems
Heczko, Lukáš ; Findura, Milan (referee) ; Vavřín, Petr (advisor)
This master´s thesis deals with control of unstable processes with two unstable complex poles using algebraic control with emphasis in value of the controller output. Thesis consists of theoretical introduction, including initial conditions with analysis of basic approaches to the control design with one or two degrees of freedom regulators by solving polynomial equations. Constrained control is studied more detailed. Optimization problem of „lowest fuel consumption“ is used for design of controller and is used for both degrees of freedom regulators with additional condition of zero variance control. Thesis includes some examples of control design by described method. Small library of MatLab functions were developed also to make the design more easier. Conclusions are made at the end and achieved goals are reviewed.

Analysis and comparison of biometric methods
Zatloukal, Filip ; Šedivá, Zuzana (advisor) ; Husa, Martin (referee)
The thesis deals with biometrics and biometric systems and the possibility to use these systems in the enterprise. Aim of this study is an analysis and description of selected types of biometric identification methods and their advantages and shortcomings. The work is divided into two parts. The first part is theoretical, describes the basic concepts of biometrics, biometric identification criteria, currently used identification systems, the ways of biometric systems use, performance measurements of selected biometric devices and biometric methods. These methods include fingerprints, hand geometry, iris, retina and facial scanning. The second part is practical and describes the implementation of security-biometric attendance system in an enterprise. In this section I test, based on selected measures and criteria, the biometric systems for the use in an enterprise. The cost of the biometric system implementation, as well as the process of its deployment, factors related to implementation and the benefits of the system are also described.
