Spread spectrum modulator
Lejsková, Alena ; Kováč, Michal (referee) ; Maršálek, Roman (advisor)
This thesis deals with a method of spectrum-spreading of the data signals transmitted in the radio channel. There exist three different ways of spreading application, they uses pseudorandom sequences and also orthogonal sequences. In these systems we can find various kinds of modulations, one of them (Quadrature Phase Shift Keying) is shown at the end of the thesis. Spectrum spreading orthogonal multiplex OFDM is based on this method. The thesis wants to present the principle of the spectrum spreading method and the description of systems, transmitters and receivers that are using this method.

Scene Analysis Based on the 2D Images
Hejtmánek, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis deals with an object surface analysis in a simple scene represented by two-dimensional raster image. It summarizes the most common methods used within this branch of information technology and explains both their advantages and drawbacks. It introduces the design of an surface profile analysis algorithm based on the lighting analysis using knowledge and experiences from previous work. It contains a detailed description of the implemented algorithm and discusses the experimental results. It also brings up options for the possible enhancement of the projected algorithm.

Bioinformatics of human genome
Kupková, Karolína ; Provazník, Ivo (referee) ; Maděránková, Denisa (advisor)
Bachelor thesis deals with DNA segments containing only adenine and guanine. The theoretical part describes the structure and composition of deoxyribonucleic acid, chromosomes and genes. There are basic informations about chimpanzees and the human genome and conformations of the chains containing adenine with guanine. The practical part consists of a program that searches for the required sections in sequence, it displays and saves it. The thesis includes analysis of genes which are common for humans and chimpanzees, which were analyzed to determine randomness, functionality a preserving of these sections.

Algorithmic Generation of Esthetical Rhytmical Sequences
Mahnert, Jakub ; Klepárník, Petr (referee) ; Beran, Vítězslav (advisor)
The goal of this project is to design and implement a system, suited for proving or disproving the claim that it is possible to generate unique rhythmical sequences, which a human will perceive as aesthetical. In the project, a framework, aiding the design of such algorithms that create rhythmical sequences using composition was implemented. On top of it, several such algorithms were implemented with the notion to test their performance using a custom testing front end solution. From the gained data, the project tries to find correlations between the aspects of the algorithms with the resulting perceived aesthetical value as well as attempt to answer the initial conundrum.

The Shortest Graph's Pahts Finding
Jágr, Petr ; Ohlídal, Miloš (referee) ; Jaroš, Jiří (advisor)
The aim of this thesis is finding, comparing and implementation of algorithms for finding the shortest paths between each of pairs of nodes in a graph. For this task I use modifications of existing algorithms to achive the lowest time consumption of the computation. Modifications are established on Dijkstra's and Floyd-Warshall's algorithm. We also familiarize with Bellman-Ford algorithm.

Measuring of Vehicle Instant Velocity
Štencel, Jakub ; Petyovský, Petr (referee) ; Horák, Karel (advisor)
The theoretical part of this paper summarizes the methods for motion analysis in an image. Inspected in detail are the methods used for motion detection in the image sequences. The practical part is focused on finding the significant points in the image (the targeting reticles on the body of the vehicle) which are then used to calculate the speed of the vehicle.

DNA Fragmnent Assembly
Paulenda, Ján ; Jaša, Petr (referee) ; Burgetová, Ivana (advisor)
The main subject of this Bachelor's thesis is the DNA fragment assembly. The problem is transposed to finding a shortest superstring problem. Different assembly techniques and string aligning methods are introduced in the theoretical part. Programming language Perl, which was used to implement the assembly, is also widely mentioned, along with its features. Last part of the thesis involves tests' statistics of the final implemented solution.

Software for retinal image processing
Magula, Filip ; Fiala, Jiří (referee) ; Kolář, Radim (advisor)
This thesis deals with practical solutions of software for retinal images digital processing. The theoretic part describes human eye and retinal anatomy and also glaucoma disease. It is also focused on description of method for retinal nerve fiber layer enhancement and analysis. These enhancement are then used for designing of automated image processing. One chapter is devoted to detection and analysis of retinal nerve fibers layer. The practical part includes the user manual for application Image Blockz, which was established within this thesis. Further practical part contains the programmer's manual describing the basic structure of the program and its possible extensions.
