Enhanced mathematical library for C++
Temel, Aleš ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
I create a library for storing matrices and working with matrices in this bachelor’s thesis. In this case, the issues concern mainly so-called sparse matrices. C++ do not provide among the standard libraries tools for easy working with sparse matrices. The most frequent alternative is the application of two-dimensional array (2D array). 2D array may be realized as a double pointer representing the rows and the columns of the matrix. The basic problem is that behavior of 2D array is identical both to the sparse, and to the full non-zero matrix. 2D array ignores the possibility to store matrices more favorable. The library for storing matrices designed by me takes into account the storing of sparse matrices by several different ways. It offers the sparse format CSR (Compressed sparse rows), as well as alternatives to save the specially structured matrices. In the course of creating library the main emphasis first of all I put on the amount of memory that is necessary for storing matrices. Because it is a mathematical library, it contains different functions suitable for working with matrices, such as determinant calculation, inverse matrix calculation and so. When calculate these functions it is necessary to take into account used memory size as well. Intermediate results are stored also in sparse format, and removed as soon as possible after their use. I created also the second library that deals with the floating point numbers stored with greater precision than standard data types like float and double. The size of occupied memory increases according to precision of floating point number.

Medical image segmentation based on graph cut with shape prior
Kozlová, Dominika ; Jan, Jiří (referee) ; Jakubíček, Roman (advisor)
This thesis deals with a graph-based image segmentation and its improvement by using the information about the shape of the object for creating specific graph architecture (template). There are described basics of the graph theory, which is the basis of the graph segmentation methods. Designed segmentation algorithm was realized in 2D with graphical user interface in MATLAB. For segmentation of volume data, the method was extended into 3D. Implemented method was tested on simulated data and on real CT and MRI images of vertebra and brain. Obtained results were evaluated and compared with the original method without using the template.

Optical Character Recognition
Bílek, Jan ; Žák, Pavel (referee) ; Zuzaňák, Jiří (advisor)
This work describes problems of optical character recognition and methods which are used to improve its results. It specializes in problems of image spam and its adjustment for its recognition. This work describes methods of processing an image which leads to better results of text recognition and also some methods used to the character recognition. There is also described a scheme and an implementation of a system which processes an image spam and detects a text within it.

Procedural Building Generation
Húsenica, Ján ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This thesis deals with procedural building generation. The method which was chosen for implementation of the tool created during this study is based on generative grammars. In this document are introduced some of the advisable methods for solving given problem. It deals with predesign, implementation and evaluation of the results of the application for procedural building generation created in this work. The final tool also allows export of the generated models to Wavefront .obj format.

Ontology-Based Content Management System
Čekan, Ondřej ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This thesis deals with the analysis, design and implementation of a system based on semantic technologies and ontology languages. There is described the semantic web and its concept, technology of semantic web especially RDF and OWL and the ability to view on the Web. Another part of this work treats with the specification, analysis, design actual implementation of the system, which processes the ontology and allows users to create individual depending on the definition of the ontology. The created content is presented on the Web annotated. The result of this work is the demonstration application.

PHP Web Application Components with a Transparent Data Binding
Loukota, Petr ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This Masters thesis deals with the design of implementation of the extension of given framework for making web applications in PHP language by a definition of website templates in XML with the possibility of implementing own additional tags in PHP. Frameworks are tools used for simple creation of web applications, and this thesis also describes systems of definitions and the utilization of templates in existing frameworks. The part of the design is also a possibility of definition of relation between state of the element of user interface and web application data. Further, the creation of sample libraries of components demonstrating functionality of the solution is described. In the conclusion, the thesis summarizes achieved results and deals with possibilities of further development.

Complex System for Web Page Creating and Editing
Jablonský, Viktor ; Vrážel, Dušan (referee) ; Kunc, Michael (advisor)
This thesis describes a system which offers customer registration and user administration-related tasks. It also facilitates an apparatus for supervising service fees. Above all, it provides users with tools with which they can create their own web site with ease and also change its content and appearance. This is achieved by using templates and modules. The Document also analyses specifications for this type of application, describes phases of design and implementation and draws out possible continuation of this project.

Electrochemical preparation of fluorescence sensor with highly ordered nanostructured surface
Bedlek, Marek ; Kolíbal, Miroslav (referee) ; Drbohlavová, Jana (advisor)
This work deals with fabrication and examination of optical properties of self-ordered TiO2 and Au quantum dots array and its potential usage in medicine as optical sensor for biomolecules detection. Controlled anodization of Ti through Al2O3 template was chosen as a fabrication method for TiO2 QDs, in case of Au galvanic deposition through Al2O3 template onto beforehand prepared TiO2 QDs or substrate with dimple structure. The influence of anodization and deposition conditions on the final structure of QDs and their emission spectrum is also examined.

Problems in Solder Paste Stencil Printing for Fine Pitch Components
Šimeček, Ondřej ; Polsterová, Helena (referee) ; Starý, Jiří (advisor)
Despote the indisputable advantages of fine-pitch components, is need to calculate with a few trouble during production, especially increased requirements for accuracy of mounting and solder printing. In this work I’m concerned with problems of solder printing for these components and evaluation using SPC. For the evaluation I used 3D paste inspection based on laser scanning of the surface. The output of this work is to describe the principles of solder printing and elaborating of GR&R, SPC analysis and histograms of solder printing for some outputs. I focused in my master thesis on motive design change of problematic components and economic evaluation of the adjustments.
